Abstract

PROBLEM TO BE SOLVED: To solve the problem in an exhaust heat recovery heat exchanger 1 of a conventional boiler 10 or turbine 32, of the cost increasing because a space is required for that part and the capacity of extra piping or pump 15 must be increased, in order to circulate the heating medium, i.e., boiler water, and it has been difficult to keep the temperature at a constant level, because the thermal conductivity is not controlled appropriately in a two-phase type heat pipe. SOLUTION: The thermal conduction apparatus comprises an opposed oscillation flow type heat pipe 2, a control box 5, and a thermosensor 6. The opposed oscillation flow type heat pipe 2 causes thermal conductivity to vary, by varying oscillation of liquid 2c by a shaker 2d. The thermosensor 6 transmits temperature information of a thermal storage tank 20 to the control box 5. Based on the temperature information, the control box 5 controls the oscillation of the shaker 2d. Thus the temperature of the thermal storage tank 20 can be controlled to be at a constant level, if the thermal conduction apparatus is used.

2. Description of the Related Art Conventionally, for example, as shown in FIG. 8, a can body 13 for storing hot water is provided for hot water supply and heating in a factory or the like, and exhaust heat recovery for recovering exhaust heat. There is a boiler 10 provided with a heat exchanger 1. The boiler 10
Is a burner 11 (heating unit) as a main power of the boiler 10.
A heat exchange unit 12 (heat exchange unit) through which exhaust gas generated by combustion of the burner 11 passes is provided in a can body 13 storing canned water, and heats the canned water in the can body 13. I have. Further, a flue 14 (exhaust system) for discharging the exhaust gas after passing through the heat exchange unit 12 and the exhaust heat recovery heat exchanger 1 to the outside, and the can water in the can 13 to the can body Pump 15 for circulating inside 13 and exhaust heat recovery heat exchanger 1, piping 1
6 and an external heat exchange unit 17 for supplying the heat energy of the boiler 10 to the outside. Normally, the exhaust heat generated by the burner 11 of the boiler 10 is discarded as it is through the flue 14, but the exhaust heat recovery heat exchanger 1 is provided at the flue 14 which is the outlet of the heat exchange unit 12. As a result, the heat energy of the discarded exhaust heat is heated by the waste heat recovery heat exchanger 1 and reused.

[0003]

In the boiler 10, the space (volume) of the boiler increases because the exhaust heat recovery heat exchanger 1 is provided between the outlet of the heat exchange section 12 and the flue. In addition, a pipe for circulating canned water is provided in the waste heat recovery heat exchanger 1, and a pressure loss of water passing through the waste heat recovery heat exchanger 1 is added. Was hanging. Further, as a heat conducting device, for example, a heat pipe or the like based on a phase change between two-phase evaporation and condensation is known, and it is conceivable to use this heat conducting device to conduct exhaust heat to the can water side. . However, a heat transfer device using a phase change such as a heat pipe mainly raises the heat conductivity, but the heat in the high-temperature portion is unilaterally transferred to the low-temperature portion without being controlled. It was only used in

[0004] That is, in a heat conduction device based on a phase change between two-phase evaporation and condensation, there is no function of controlling the amount of heat flowing. Therefore, the heat absorbed by the heat receiving portion is automatically carried, and the heat must be radiated by the heat radiating portion. . Therefore, in the case of using the exhaust heat of the boiler described above, in the conventional heat conducting device,
The heat transfer of the exhaust heat to the can water cannot be controlled, and when there is no heat consumption load, there is a possibility that the heat transfer device may overheat at the heat radiating portion to the can water. Further, it was not possible to control the backflow of heat when the boiler was shut down and the temperature of the flue 14 dropped below the can water. On the other hand, in a boiler provided with a heat storage tank for storing the amount of heat of exhaust heat, the conventional heat transfer device cannot control the heat conductivity as appropriate, so that it is used in the heat storage tank to balance the heat consumed. It was difficult to keep the temperature of the heat medium in the heat storage tank constant. However, in actual daily life, heating and hot water supply using heat require an absolute amount of heat, but it is more important to always maintain a comfortable and usable temperature level.

[0005] Further, when an attempt is made to construct, for example, a cooling and heating system for a building such as a building by using a conventional two-phase heat pipe, that is, a heat transfer between an outdoor unit and an indoor unit is performed. When a pipe is used and the outdoor unit is installed on the roof, the following problems occur. That is, at the time of heating, if a conventional two-phase heat pipe is used for heat transport, the heat radiating portion is located below the heat receiving portion, and if the distance between them becomes long, even if the liquid sealed in the heat pipe evaporates. Since it does not descend, the function of the heat pipe is extremely reduced. An object of the present invention is to provide a heat conduction device, a boiler, a power generation device, and a heating / cooling device which are provided with controllability of a heat transport amount and use a liquid one-phase oscillating flow type heat pipe as a heat conduction member. It is.

[0006]

According to a first aspect of the present invention, as shown in FIGS. 1 and 3, a plurality of flow passages extending in parallel between a high temperature portion and a low temperature portion are provided. A flow path including a portion (2e), a liquid (2c) sealed in a state substantially filled in the flow path, and the liquid coming and going in the flow path along the extending direction of the flow path portion. (Vibrator 2d) for vibrating the liquid in such a manner that the liquids in the flow path portions adjacent to the flow path are arranged adjacent to each other across a wall (flow path wall 2b), and In a state where the liquids in the adjacent flow paths are vibrated so that the liquids in the adjacent flow paths have the opposite phases, the liquids in the adjacent flow paths exchange heat through the wall. A heat conduction device using a heat conduction member (opposing oscillating flow heat pipe 2) capable of increasing the heat conductivity, Signal output means for outputting the connected signal equipment, such as a seed sensor device (thermosensor 6)
And controlling at least one of the start and stop of the vibration applied to the liquid by the vibrating means, the amplitude of the vibration, and the frequency of the vibration based on the signal output from the signal output means. And a control means (control box 5) for controlling the operation and stop of the vibration means.

According to the above arrangement, for example, the signal output means is a temperature measurement means having a sensor for measuring temperature and outputting a signal indicating the measured temperature, and the temperature measurement means is provided in the low-temperature section. When the temperature is measured, the temperature measuring unit senses the temperature of the low-temperature part and sends a signal to the control unit, and the control unit uses the signal to control the amplitude and frequency of the vibration of the vibration unit inside the heat conducting member and the vibration. The activation and deactivation of the means can be controlled. Further, since the heat conductive member has a function of changing the thermal conductivity of the heat conductive member when the vibration of the liquid inside the heat conductive member changes, the heat is transmitted from the high temperature part to the low temperature part. The amount of heat, that is, the amount of heat transport, can be appropriately controlled by the temperature of the low temperature section. Therefore, the heat conduction device can perform control for keeping the temperature of the low-temperature portion substantially constant.

Further, when the temperature measuring means is provided in the high temperature section, the temperature measuring means senses the temperature of the high temperature section and sends a signal to the control means. It is possible to control at least one of the amplitude and the frequency of the vibration of the vibration means inside the heat conducting member, and to control the operation and stop of the vibration means. At this time, when the temperature of the high-temperature section exceeds a predetermined temperature, the vibrating means is stopped, and when the temperature is equal to or lower than the predetermined temperature, the vibrating means is controlled to operate. If the temperature is set near the temperature below the limit at which the heat conducting member can conduct heat, the life of the heat conducting member can be extended. Further, when the temperature of the high-temperature portion exceeds a predetermined temperature, the vibrating means is operated, and when the temperature is equal to or lower than a predetermined temperature, the vibrating means is controlled to stop. If the temperature is set to the low-temperature part, it is possible to prevent the backflow phenomenon of the heat transport amount from the low-temperature part to the high-temperature part caused by the temperature of the low-temperature part being higher than the temperature of the high-temperature part. . The signal output means is not limited to the above-described temperature measurement means. For example, the signal output means outputs a signal in response to the on / off of the heat source on the high temperature part side, and heat is transmitted by the heat conduction device of the present invention. A signal may be output in response to the start and stop of the supply of the heated medium.

According to a second aspect of the present invention, there is provided a flow path having a plurality of flow paths extending in parallel between the high temperature section and the low temperature section, and the flow path is sealed in a substantially filled state. A liquid, and vibrating means for vibrating the liquid so as to move back and forth in the flow path along the extending direction of the flow path, wherein the liquids in the flow path adjacent to the flow path are separated by a wall. Are arranged adjacent to each other, and in a state where the liquid in the adjacent flow path portion is vibrated such that the vibrations by the vibrating means have opposite phases between the liquids in the adjacent flow path portions, A heat conducting device using a heat conducting member in which liquids exchange heat through a wall, wherein at least one of a high-temperature portion heat-receiving portion and a low-temperature portion-side heat radiating portion of the heat conducting member receives heat or radiates heat. The heat pipe or metal member is connected so that the heat transfer surface is widened. .

According to the above construction, the heat conducting device according to the second aspect is effective when conducting heat from a heat source having a high temperature exceeding the boiling point of the liquid sealed in the heat conducting member. It will be. That is, for example, when the heat source is a heat medium having a temperature higher than the boiling point of the liquid to be sealed in the heat conductive member (for example, a gas such as exhaust gas from a boiler or a gas turbine), the heat receiving portion of the heat conductive member is directly contacted with the heat medium. When you do
The sealed liquid may evaporate and the internal pressure may increase.Use a liquid with a high boiling point as the liquid to be sealed in the heat conducting member, or withstand the pressure of the heat conducting member to prevent the sealed liquid from evaporating. It is necessary to take measures such as raising

Therefore, if the heat radiating portion of the heat pipe is joined to the heat receiving portion of the heat conducting member by the two-phase change of evaporation and condensation, the following effects can be obtained. In other words, in the conventional heat pipe, the medium is sealed in a two-phase state of gas and liquid,
It has a structure in which gas that has evaporated originally exists in the flow path of the conventional heat pipe. Therefore, for example, even if the temperature of the exhaust gas of the heat source recovered by the heat receiving portion of the conventional heat pipe significantly exceeds the boiling point of the sealed liquid, and reaches 300 ° C. if the sealed liquid is water, there is no problem. Rarely occurs. Then, when the temperature of the heat-conducting member of the heat-conducting device of the present invention is reduced to about the boiling point of the liquid sealed in the heat-conducting member at the joint where the heat-dissipating portion of the conventional heat pipe is connected to the heat-receiving member of the heat-conducting member. The heat transfer device functions normally.

Further, simply contacting the heat receiving portion of the heat conducting member with, for example, a heat medium (fluid) as a heat source limits the area of a heat transfer surface used for heat exchange with the heat medium. By connecting a conventional heat pipe to the heat receiving portion, the heat transfer surface can be increased, and the heat received by the heat pipe with high heat conductivity can be transmitted to the heat conductive member. In order to widen the heat transfer surface of the heat pipe with the heat medium, it is preferable that the heat pipe has a meandering flow path and that the number of reciprocating meanders is increased.

Also, in the heat radiating portion of the heat conducting member, the heat can be efficiently radiated by connecting the heat pipe and expanding the heat transfer surface. Further, in expanding the heat transfer surface, it is not always necessary to use a heat pipe, and a metal having a high heat conductivity may be connected to the heat receiving portion or the heat radiating portion of the heat conductive member. It is preferable to use a heat pipe in consideration of the heat transport amount.

A boiler according to a third aspect of the present invention is a boiler (10) as shown in FIG. 2 using the heat conducting device according to the first aspect, comprising: a can body (13) having water; A heating section (burner 11) for heating the can water, a heat exchange section (12) for transferring heat from the heating section to the can water, and an exhaust system (flue 14) for discharging exhaust gas from the heating section; The heat conducting member that conducts heat from the exhaust system to the can water, and a temperature measuring unit that includes a sensor that measures the temperature of the can water and serves as the signal unit that outputs a signal indicating the measured temperature; and The control means for controlling the vibration means of the heat conduction member, the control means, the heat conduction member has a high heat conductivity of the exhaust system until the temperature of the water reaches near a predetermined temperature The vibrating means is controlled so as to conduct heat to the water, and the temperature of the water is adjusted to a predetermined temperature. When reaching the is characterized in that the thermal conductivity of the heat conductive member controls the vibrating means so as the temperature of the boiler water to maintain a substantially predetermined temperature.

According to the above configuration, when the temperature of the can water is equal to or lower than the predetermined temperature, the can water is rapidly heated by the heat exchange section and the heat conductive member having a high thermal conductivity. Is done. Then, when the temperature of the water reaches a predetermined temperature, the temperature measuring means installed in the water detects the temperature of the water and outputs a signal indicating the temperature, and the signal indicates the temperature. Input to the control means. The control means appropriately controls the vibrating means so as to lower the thermal conductivity of the heat conductive member and maintain the temperature of the canned water at a substantially predetermined temperature. From the above, the heating of the can water can be assisted by the heat conducting member that conducts heat from the exhaust system to the can water. Further, the temperature measuring means senses the temperature of the canned water and sends a signal indicating the temperature to the control means, and the control means controls the amplitude and the frequency of the vibration means by the signal. By doing so, it is possible to control the thermal conductivity of the heat conductive member and control to keep the temperature of the canned water constant.

A boiler as used herein is defined as a device that generates water or steam by heating water in a can (container) with heat from a heat source. It is not limited to "water heaters" and "water heaters" used in product names. Therefore, as the boiler, one using a container opened to the atmosphere as a can body for storing hot water,
There are those using a pressure vessel, those using a vacuum vessel to maintain the inside of the vessel at a negative pressure, and any of those belonging to general boilers, water heaters and water heaters.

A boiler according to a fourth aspect of the present invention is a boiler using the heat conduction device according to the first aspect, as shown in FIG. A heating unit, a heat exchange unit that transfers heat from the heating unit to the can water, an exhaust system that discharges exhaust gas from the heating unit, and a heat storage unit (heat storage tank 20) that stores heat released from the exhaust system. ) And the heat conducting member that conducts heat from the exhaust system to the heat storage unit;
A temperature measurement unit that includes a sensor that measures the temperature of the heat storage unit and serves as the signal unit that outputs a signal indicating the measured temperature, and the control unit that controls a vibration unit of the heat conduction member, The control means controls the vibrating means so that the heat conducting member conducts the heat of the exhaust system to the heat accumulating section with a high thermal conductivity until the temperature of the heat accumulating section approaches a predetermined temperature. When the temperature of the water reaches the vicinity of the predetermined temperature, the vibrating means is controlled so that the thermal conductivity of the heat conduction member keeps the temperature of the heat storage section substantially at the predetermined temperature. I do.

According to the above construction, the heat storage section can be heated by the heat conducting member that conducts heat from the exhaust system to the heat storage section, and the temperature measuring means can control the temperature of the heat storage section. Sensing and sending a signal to the control means,
The control means controls the thermal conductivity of the heat conducting member by controlling the amplitude and frequency of the vibration means by the signal, and controls the temperature of the heat storage unit to be constant. It can be performed.

According to a fifth aspect of the present invention, in the boiler according to the third or fourth aspect, the signal output means indicates the start / stop of heating when starting / stopping the heating of the can water by the heating unit. A heating signal output unit for outputting a signal is provided, and the control unit controls the start / stop of the vibration of the vibration unit in conjunction with the start / stop of the heating unit.

According to the above arrangement, a signal is sent to the control means indicating that heating by the boiler has been stopped, so that the control means stops the vibration of the vibrating means. Further, when the vibration means stops, the heat conductivity of the heat conducting member extremely decreases. Therefore, the control means stops the vibration of the vibration means when there is no need for heat conduction, thereby increasing the overall efficiency, and when the boiler normally stops, the temperature of the exhaust system is reduced to the canned water or water. Although the temperature of the heat storage unit is lowered, and the calorie of the can water and the like is released to the exhaust system, the heat conduction of the heat conducting member is cut off by stopping the vibrating means. Loss can be prevented.

A boiler according to a sixth aspect of the present invention is, for example, as shown in FIG. 5, a boiler for supplying hot water using the heat conducting device according to the first aspect. A heating section for heating the can water, a heat exchange section for transferring heat from the heating section to the can water, an exhaust system for discharging exhaust gas from the heating section, and a hot water supply / heating system using the can water. Circuit (external heat exchange unit 17) for generating hot water used for

According to the above configuration, in a boiler (water heater) provided with a circuit for generating hot water using heated can water (which may be vaporized into steam), a circuit for generating hot water Is preheated by the exhaust heat conducted by the heat conducting member. As a result, the amount of heat required in the circuit is reduced, and the efficiency of the boiler can be increased. In such a boiler,
Water supply is performed while hot water is being used, and water supply is stopped when hot water is not being used. On the other hand, the heating section side of the boiler basically operates such that the water in the can body is maintained at a predetermined temperature. Therefore, the start and stop of heating of the heating unit and the start and stop of water supply by the water supply unit do not always match. Therefore, when the exhaust heat is transmitted to the water supply side pipe without control, the pipe is heated even while the water supply is stopped, and the water stopped inside the pipe may be overheated. Therefore, in the case of such a configuration, it is necessary to change the control of the heating unit, for example, by considering the temperature of the water supply pipe side.However, while the water supply is stopped, the heating of the heating unit is stopped. If the control is performed, there is a possibility that the temperature of the can water in the can body decreases, and a problem such as a decrease in the temperature of the hot water when the water supply is restarted may occur.
However, in the present invention, when the water supply is stopped by the control means, the vibration means of the heat conduction member is controlled, and the heat conductivity of the heat conduction member is extremely reduced. Thus, even if the heating unit is not controlled in consideration of the above, it is possible to prevent the water supply pipe from being overheated when the water supply is stopped.

A power generating device according to a seventh aspect of the present invention is a power generating device (30) using the heat conducting device according to the first aspect as shown in FIG.
A power generation unit (generator 34) for generating power by rotation of the gas turbine, an exhaust system (flue 36) for discharging exhaust gas from the gas turbine, and a heat storage unit for storing heat released from the exhaust system. The heat conducting member that conducts heat from the exhaust system to the heat storage unit, and a temperature measurement unit that includes a sensor that measures the temperature of the heat storage unit and serves as the signal unit that outputs a signal indicating the measured temperature; and The control means for controlling the vibrating means of the heat conducting member, wherein the control means keeps the heat conducting member with a high heat conductivity until the temperature of the heat storage unit reaches a predetermined temperature. The vibrating means is controlled so as to conduct the heat to the heat storage unit, and when the temperature of the canned water reaches a predetermined temperature, the heat conductivity of the heat conductive member increases the temperature of the heat storage unit to approximately the predetermined temperature. Control the vibration means so that it is maintained. The features.

According to the above configuration, the heat storage member can be heated by the heat conducting member that conducts heat from the exhaust system to the heat storage unit, and the temperature measuring means can control the temperature of the heat storage unit. Sensing and sending a signal to the control means,
The control means controls the thermal conductivity of the heat conducting member by controlling the amplitude and frequency of the vibration means by the signal, and controls the temperature of the heat storage unit to be constant. It can be performed.

According to an eighth aspect of the present invention, in the power generator according to the seventh aspect, when the operation of the gas turbine is started or stopped, a signal indicating the start or stop of the operation is output as the signal output means. Operating signal output means for controlling the start and stop of the vibration of the vibrating means in conjunction with the start and stop of the operation of the gas turbine.

According to the above arrangement, a signal is sent to the control means indicating that the heating by the gas turbine has been stopped, so that the control means stops the vibration of the vibration means. Further, when the vibrating means stops, the heat conduction member is in a state where almost no heat is transmitted. Therefore, when the control means does not need to conduct heat, the vibration of the vibrating means is stopped to increase the overall efficiency, and normally, when the gas turbine is stopped, the temperature of the exhaust system is reduced. It drops below the temperature,
Although the calorie of the heat storage section is released to the exhaust system, the heat conduction of the heat conducting member is cut off by stopping the vibrating means, so that this useless calorie loss can be prevented.

A power generator according to a ninth aspect of the present invention is a power generator using the heat conduction device according to the first aspect, comprising: a gas turbine; a power generator for generating power by rotating the gas turbine; An exhaust system that discharges exhaust gas, a circuit for generating hot water used for hot water supply, heating, and the like using residual heat of the exhaust system, a water supply side pipe of the circuit, and a circuit connected to the water supply side pipe, Water supply means for supplying water to the circuit, the heat conducting member that conducts heat from the exhaust system to the water supply side pipe, and the signal output means that is connected to the water supply means and outputs a signal indicating start / stop of water supply. Water supply signal output means, and the control means for controlling the vibration means of the heat conducting member, wherein the control means starts the vibration of the vibration means in conjunction with the start / stop of water supply by the water supply means.・ Specially controlling stop To.

According to the above configuration, in a power generator capable of supplying hot water using exhaust heat at the time of power generation by the gas turbine, the same effect as that of the boiler according to claim 6 can be obtained. That is, in this power generation device, when hot water is supplied using exhaust heat, water supplied to a circuit for generating hot water is preheated in advance by the exhaust heat conducted by the heat conducting member, and the heat in the circuit is reduced. In a configuration in which the load can be reduced, while the hot water is not consumed and the water supply is stopped, the heat conductivity of the heat conductive member can be extremely reduced to prevent the supplied water from overheating. . In addition, by reducing the load of a circuit that generates hot water by warming the supplied water, it is possible to reduce the energy used for the burner when the amount of hot water is large and a burner is additionally required. In addition, it is possible to adopt a configuration that does not require the use of an auxiliary burner.

A heating device according to a tenth aspect of the present invention is a heating / cooling device using the heat conduction device according to the first or second aspect, wherein the low-temperature side of the flow path of the heat conduction member is heated.・
It is characterized by being a heat radiating means for various kinds of heating such as snow melting, or a cooling means for various kinds of cooling such as cooling and refrigeration on the high temperature side of the flow path of the heat conducting member.

According to the above construction, the heat from the heat source is conducted by the heat conducting member, and the low-temperature side of the flow path of the heat conducting member is used as a heat radiating plate (heat radiating means) for heating and melting snow. Heating can be performed by radiation and convection, and snow melting can be performed by direct heat conduction and the like. Also,
When melting snow or heating, as a heat source, not only combustion of gas, kerosene and the like, electric heaters, but also natural energy such as hot springs and geothermal can be effectively used.

If the signal output means is connected to a temperature sensor and outputs a signal indicating, for example, the room temperature of the room to be heated, the signal output means can control the thermal conductivity of the heat conductive member. Room temperature can be controlled.
In this case, since it is not always necessary to control the temperature of the heat source to control the room temperature, heat sources such as natural energy, such as hot springs and geothermal, which cannot basically control the temperature, power generation, and incineration of garbage can be used. For example, in the case of a heat source whose temperature is controlled for a purpose other than the control of the room temperature, such as residual heat and waste heat accompanying the temperature control, the room temperature can be controlled without controlling the temperature of the heat source.

When the heat conducting member of this heating device is used for melting snow, the heat conducting member is assumed to have a wide width as described above, and is arranged on the road surface or below the road surface, and It will melt the snow. In this case, for example, in addition to the temperature control as in the case of heating, a snowfall meter, a means for detecting snowfall / rainfall, or water (ice) on the road surface may be provided with the amount of snowfall, snowfall, rainfall, and presence of water. May be connected, and only when there is snow, ice, or water on the road surface, the heat conductivity of the heat conducting member may be increased to perform snow melting or the like. In the case of snow melting, low-cost snow melting can be achieved by using natural energy such as hot springs and geothermal heat as a heat source as described above.

It is preferable to increase the area of the portion of the flow path serving as the heat radiating plate by, for example, meandering the entire flow path within the thickness of the flow path in a state where the flow paths are arranged in parallel. At this time, the meandering portions are in contact with each other, and are formed in a plate shape wider than the width of the flow path, or in a stripe shape (a portion excluding a bent or curved portion), a wavy shape, or a zigzag shape in which the meandering portions are separated from each other. Shape or comb shape.
Furthermore, the channel portion made into a wide plate shape by meandering,
The portion having an area larger than the width of the flow channel may be further meandered so as to be curved or bent in a direction perpendicular to the surface of the plate-shaped portion, and may be formed in a wavy shape, a zigzag shape, or a comb tooth shape. . Further, in the present invention, a cooling device may be used with the heat source as a cold heat source. The configuration of the cooling device can be basically the same as the configuration of the heating device except that the temperature of the heat source is different. Further, as the cold heat source, one using a compressor, one using an element that cools by applying a voltage, spring water, well water, ice, or the like can be used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a heat conduction device, a boiler, a power generation device, and a heating / cooling device according to the present invention will be described below with reference to the drawings. The counter-oscillating flow heat pipe 2 shown in FIG. 1 is used as a heat conducting member used in the heat conducting device of the present invention. The opposed oscillating flow heat pipe 2
Has a thin plate-like body 2a as a whole. The plate 2a
The interior is in a state where the flow paths meander so as to reciprocate from the high-temperature section to the low-temperature section, and the respective flow path sections 2e are arranged in parallel between the high-temperature section and the low-temperature section. In addition, the flow path portions 2e arranged in parallel are separated from each other by a flow path wall 2b, and each flow path section 2e is connected to a flow path section 2e on the right side on one end side, The flow path is a closed circuit circulation flow path by being connected to the flow path section 2e on the left side on the other end side, and further connected to the flow path sections 2 on the left and right ends. The inside of the closed circuit circulation flow path is filled with a liquid 2c serving as a medium for transmitting heat in a state where the liquid 2c is substantially filled in the flow path. The liquid 2c is moved by a vibrator 2d (vibration means) installed in the flow path.
In the flow path, the direction toward the high temperature part (Hot side) and the low temperature part (Cold
It vibrates so that it moves back and forth with the direction toward side).
In addition, since the liquid 2c vibrates in the meandering flow path,
The liquids 2c adjacent to each other across the flow path wall 2b have phases opposite to each other.

The counter-oscillating flow heat pipe 2
The mechanism for transmitting the heat of the first embodiment will be described. First, the liquid 2c whose temperature is lower than the wall temperature shaken by the vibration in the high-temperature portion,
The liquid 2c having the opposite phase adjacent thereto across the flow path wall 2b absorbs the heat carried from the high temperature portion through the flow path wall 2b.
Then, the liquid 2c that has absorbed the heat quantity carries the heat quantity to the low temperature part. Thereafter, since the temperature of the liquid 2c that has been shaken to the low-temperature portion is higher than the wall temperature, the amount of heat is radiated to the liquid 2c that has shaken to the adjacent high-temperature portion across the flow path wall 2b through the flow path wall 2b. By repeating these operations, heat is transferred from the high-temperature portion to the low-temperature portion. Therefore, as compared with the heat medium that moves along with the heat medium by moving the heat medium in the flow path, the heat medium that conducts the heat through the adjacent flow path wall 2b as in the present invention is more preferable. It can carry a large amount of heat transport. Further, when the vibration frequency of the vibrator 2d is increased, the above-described operation is performed earlier, so that the thermal conductivity is improved. On the other hand, when the vibration frequency is reduced, the above-described operation is performed later, so that the thermal conductivity is reduced. Further, by increasing the amplitude, the distance of heat transfer by one vibration is extended and the thermal conductivity is improved, and when the amplitude is reduced, the thermal conductivity is reduced. By changing the frequency and amplitude of the vibrator 2d in this manner, the thermal conductivity is between the square root of the frequency and the square (depending on the frequency range) and the square of the amplitude of the oscillating flow of the liquid. Because it is proportional, the way heat is transmitted can be varied over a wide range.

Next, a heat conduction device and a boiler as a first example of the present invention will be described below. The boiler 10 shown in FIG. 2 includes a burner 11 (heating unit) as a main power of the boiler 10, and a heat exchange unit 12 (heat exchange unit) through which exhaust gas generated by combustion of the burner 11 passes stores canned water. Is provided in the can body 13, and heats the can water in the can body 13. A flue 14 (exhaust system) for discharging the exhaust gas after passing through the heat exchange section 12 to the outside;
Pump 15 and piping 16 for circulating the water in 3
And an external heat exchange unit 17 for supplying the heat energy of the boiler 10 to the outside. The boiler 10 is provided with a heat conducting device of the present invention described below, and basically employs a well-known configuration except for a configuration for heating canned water using exhaust heat by the heat conducting device and a control method therefor. It is almost the same as a water heater using an open container. In the heat conduction device, the opposed oscillating flow heat pipe 2 is used as a heat conduction member.
A heat receiving portion 3 for absorbing heat from the exhaust gas of the burner 11 is provided at a high temperature portion of the opposed oscillating flow heat pipe 2, and a can body 13 is provided at a low temperature portion for the heat from the opposed oscillating flow heat pipe 2. A radiator 4 for radiating the transmitted heat is provided. The heat receiving unit 3 is installed in the flue 14, and the heat radiating unit 4 is installed in the can 13. A control box 5 (control means) for controlling the frequency and amplitude of the vibrator 2d by temperature is connected to the vibrator 2d provided inside the opposed vibrating flow heat pipe 2, and the control box 5 is provided on the outer wall of the can 13. In addition, a thermosensor 6 (temperature measuring means) is provided in the can 13 to sense the temperature of the water in the can 13. The temperature detected by the thermosensor 6 is output to the control box 5 as a signal indicating the temperature by a signal output unit (not shown) provided in the thermosensor 6.

Here, the opposed oscillating flow type heat pipe 2
As shown in FIG. 3, the heat receiving section 3 provided in the high temperature section of
It is composed of a conventional heat pipe 3a based on a phase change between two-phase evaporation and condensation, and a heat transfer plate 3b made of a metal material or the like. On the other hand, the heat radiating section 4 has the same configuration as the heat receiving section 3. Here, since the conventional heat pipe 3a has a meandering flow path, the opposed oscillating flow heat pipe 2a
Are not adjacent to each other across the flow path wall 2b. Therefore,
By increasing the number of reciprocating meanders, the surface area can be easily increased. Next, a mechanism for transmitting heat from the heat receiving unit 3 to the opposed oscillating flow heat pipe 2 will be described. First, the conventional heat pipe 3a is connected to the flue 1
4 receives heat. The amount of heat received by the conventional heat pipe 3a flows through the conventional heat pipe 3a and is transmitted to the heat transfer plate 3b. And the heat quantity is the heat transfer plate 3b
And flows to the opposed oscillating flow heat pipe 2.
On the other hand, in the heat radiating portion 4, the amount of heat transmitted in the reverse order to the above is radiated to the water in the can 13.

As described above, by providing the heat receiving section 3, the surface area of the conventional heat pipe 3a becomes larger than the surface area of the opposed oscillating flow heat pipe 2, so that the efficiency of receiving heat from the flue 14 increases. At the same time, the heat dissipating portion 4 also has the same operation as described above, so that the efficiency of dissipating the amount of heat into the can 13 increases, so that the overall heat transfer efficiency of the heat conduction device can be increased. Further, since the opposed oscillating flow type heat pipe 2 is sealed in a state where the liquid 2c is almost completely filled in the flow path, if the exhaust heat is directly received by the high temperature portion, the exhaust heat temperature becomes the boiling point of the liquid 2c. If the temperature becomes higher than the temperature, it may not function properly. On the other hand, the conventional heat pipe 3a
There is already evaporated gas inside. Therefore, when the exhaust heat temperature greatly exceeds the boiling point temperature of the liquid sealed in the conventional heat pipe 3a, even if the sealed liquid is water, the conventional heat pipe 3a has a temperature of about 300 ° C. It has a structure that can withstand up to. Therefore, the exhaust heat can be directly received by the conventional heat pipe 3a.
Furthermore, if the temperature of heat reaching the opposed oscillating flow heat pipe 2 is set so as not to reach the boiling point of the liquid 2c by utilizing the heat loss in the conventional heat pipe 3a and the heat transfer plate 3b, The oscillating flow heat pipe 2 can be used under appropriate conditions. The member for receiving and radiating the heat of the flue 14 and the can 13 is not limited to the conventional heat pipe 3a, and may be, for example, a multi-layered metal plate. In addition, any metal member having a large surface area and capable of conducting heat may be used. Further, the external heat exchange section 17 is for heating the water supplied to the external heat exchange section 17 with the heat of the heated canned water to generate hot water and supply hot water.

Next, the operation of the heat conduction device when the boiler 10 in the first example is operating will be described. First, when the main power of the burner 11 is turned on to heat the water in the can 13, the power of the vibrator 2 d, the power of the thermosensor 6, and the control box 5 are also turned on.
Then, the temperature of the water in the can 13 is detected by the thermo sensor 6, and the information is transmitted to the control box 5.
Here, the can water temperature in the can body 13 is still room temperature (for example, 2
0 ° C.), and if the can water temperature does not reach the lower limit (for example, 67 ° C.) of a preset can water set temperature in the can 13, the control box 5 An instruction is given to 2d to set the vibrator 2d to the Hi mode, and the vibrator 2d is vibrated at a high speed. The shaker 2d
Vibrates at a high speed, the heat conductivity of the opposed oscillating flow heat pipe 2 increases, and a large amount of heat is
Conducts to the can water in 3. Since a large amount of the heat is radiated from the radiator 4, the temperature of the water in the can 13 rises rapidly.

When the temperature of the water reaches the lower limit of the set temperature of the water, the control box 5 turns on the vibrator 2.
An instruction is given to the controller d to set the vibrator 2d to the low mode, and the vibrator 2d is vibrated at a low speed. The shaker 2d
Vibrates at a low speed, the thermal conductivity of the opposed oscillating flow heat pipe 2 becomes low, and a relatively small amount of heat is conducted to the water in the can 13. The small amount of the heat is
Since the heat is further dissipated, the temperature rise of the can water in the can 13 becomes gentler than when the vibrator 2d is in the Hi mode. When the temperature of the can water gradually rises, and eventually exceeds the upper limit of the set can water temperature (for example, 73 ° C.), the control box 5 causes the vibrator 2 d to
A command to forcibly stop the vibrator 2d is given to stop the vibrator 2d. When the vibrator 2d stops, the opposed oscillating flow heat pipe 2 substantially blocks the heat conduction from the heat receiving unit 3.

The can body 1 whose heat conduction has been cut off
The temperature of the canned water in 3 no longer rises, but slowly begins to fall. The temperature of the can water decreases rapidly, and reaches a predetermined temperature within the range of the can water set temperature (for example, 68.
5 ° C.), the control box 5
d, a command to start the vibrator 2d again in the low mode is issued, and the vibrator 2d starts vibrating at a low speed. By starting the vibrator 2d, the heat transfer function of the opposed oscillating flow heat pipe 2 is also restored, and a small amount of heat is transmitted from the heat receiving unit 3 to the heat radiating unit 4. Then, the temperature of the can water in the can 13 also starts to gradually rise again. However, when the working load is large and the water temperature further drops and falls below the lower limit of the above-mentioned water setting temperature (for example, 67 ° C.), for example, becomes 60 ° C. or less, a command to set the Hi mode is given again, and the operation is started. The same operation as that at the time of start is performed. By repeating the above operation, in the region from the upper limit to the lower limit of the preset canned water temperature in the can 13, plays an auxiliary role of the heat exchange unit 12 that supplies heat to the canned water, Fine adjustment of canned water heating between the regions can be performed.

Therefore, according to the first embodiment of the present invention, the use of the opposed oscillating flow heat pipe 2 makes it possible to reuse the heat of the exhaust gas by the burner 11 and to use the opposed oscillating flow heat pipe. When there is no need to supplementally heat the canned water, the vibrator 2d stops, so that the effect of energy saving can be improved. Further, the can water can be heated while finely adjusting the can water in the can body 13. Further, the opposed oscillating flow heat pipe 2 only needs to connect the heat receiving section and the heat radiating section, and the exhaust recovery heat exchanger 1 used as a conventional heat conducting device as shown in FIG.
Unlike large-scale equipment that circulates canned water as a heat medium to pipes inside the exhaust heat recovery heat exchanger 1 and transfers heat to the can 13, the installation space for transferring only heat is small. There is no need to make the boiler equipment compact. Further, since there is no need to circulate can water in the exhaust heat recovery exchanger 1 by the pump 15 as in the conventional exhaust heat recovery exchanger 1, the capacity of the pump 15 is increased or the number thereof is increased. This eliminates the need and reduces costs. Furthermore, as compared with a heat transfer device provided with another pump, the opposed oscillating flow type heat pipe 2 has fewer components, so that the manufacturing cost is reduced. In addition, the power for generating vibration is only about one-tenth of the power for circulating can water, and energy can be saved.

A heat conduction device and a boiler as a second example of the present invention will be described below. Boiler 10 shown in FIG.
Is provided with a heat storage tank 20 (heat storage unit) and is configured to be able to use the heat of the heat storage tank 20 separately from the water in the can body 13, and the heat conduction device of the present invention is configured as in the first example. Exhaust heat can 13
The configuration is substantially the same as that of the boiler 10 of the first example, except that the heat is not conducted to the inside, but to the heat storage tank 20. The description is omitted by attaching the reference numerals. The heat storage tank 20 is filled with a heat medium 21 such as water so that hot water or the like can be supplied.

In the heat conducting device, the above-mentioned counter-oscillating flow type heat pipe 2 is used as a heat conducting member, and heat is absorbed from the exhaust gas of the burner 11 into a high temperature portion of the counter-oscillating flow type heat pipe 2. The heat receiving section 3 and the heat storage tank 20 in the low temperature section.
A heat radiating section 4 for radiating heat transmitted from the opposed oscillating flow heat pipe 2 to a heat medium 21 in the inside is provided. The heat receiving section 3 is installed in the flue 14, and the heat radiating section 4 is installed in the heat storage tank 20. A control box 5 for controlling the frequency and amplitude of the vibrator 2d by temperature is connected to the vibrator 2d provided inside the opposed vibrating flow heat pipe 2, and the control box 5 It is provided on the outer wall of the tank 20. Further, a thermosensor 6 is provided in the heat storage tank 20 to detect the temperature of the heat medium 21 in the heat storage tank 20. Then, information detected by the thermosensor 6 is transmitted to the control box 5 as a signal.

Next, the operation of the heat conduction device when the boiler 10 in the second example is operating will be described. First, when the main power of the burner 11 is turned on to heat the water in the can 13, the power of the vibrator 2 d, the thermosensor 6, and the control box 5 is also turned on.
Then, the temperature of the heat medium 21 in the heat storage tank 20 is detected by the thermosensor 6, and information is transmitted to the control box 5. Here, the temperature of the heat medium 21 in the heat storage tank 20 is still normal temperature (for example, 20 ° C.), and the temperature of the heat medium 21 is lower than the preset heat medium set temperature in the heat storage tank 20 (for example, (67 ° C.), the control box 5 gives a command to the vibrator 2d to set the vibrator 2d to the Hi mode, and vibrates the vibrator 2d at high speed. When the vibrator 2d vibrates at a high speed, the heat conductivity of the opposed oscillating flow heat pipe 2 increases, and a large amount of heat is transmitted to the heat medium 21 in the heat storage tank 20. At this time, since a large amount of heat is radiated from the heat radiating section 4, the temperature of the heat medium 21 in the heat storage tank 20 rapidly rises. Eventually, when the temperature of the heat medium 21 reaches the lower limit of the heat medium set temperature, the control box 5 gives a command to the vibrator 2d to set the vibrator 2d to a low mode, and The vibrator 2d is vibrated at a low speed.

When the vibrator 2d vibrates at a low speed, the heat conductivity of the opposed oscillating flow heat pipe 2 decreases, and a relatively small amount of heat is transferred to the heat medium 21 in the heat storage tank 20.
To conduct. Since a small amount of heat is radiated from the radiator 4, the temperature of the heat medium 21 in the heat storage tank 20 rises more slowly than when the vibrator 2d is in the Hi mode. Thereafter, the temperature of the heat medium 21 gradually rises, and when the temperature exceeds the upper limit of the heat medium set temperature (for example, 73 ° C.), the control box 5 causes the vibrator 2d to move toward the vibrator 2d. Is forcibly stopped, and the vibrator 2d is stopped. When the vibrator 2d stops, the opposed oscillating flow heat pipe 2 substantially blocks the heat conduction from the heat receiving unit 3.

The temperature of the heat medium 21 in the heat storage tank 20 in which the heat conduction has been cut off does not rise, but gradually starts to fall. When the temperature of the heat medium 21 decreases rapidly and falls below a certain temperature (for example, 68.5 ° C.) within the range of the heat medium set temperature, the control box 5 sends the vibration to the vibrator 2d. When the vibrator 2d is Lo again
A command to start in the w mode is issued, and the vibrator 2d starts vibrating at a low speed. By starting the vibrator 2d,
The heat transfer function of the opposed oscillating flow heat pipe 2 is also restored,
A small amount of heat is transmitted from the heat receiving section 3 to the heat radiating section 4. Then, the temperature of the heat medium 21 in the heat storage tank 20 also starts to gradually rise again. However, the use load is large and the heat medium temperature further drops, and the lower limit of the heat medium set temperature (for example, 6
7 ° C), for example, when the temperature falls below 60 ° C, Hi
A command to set the mode is given again, and the same operation as when starting the operation is performed. By repeating the above operation, the temperature of the heat medium 21 in the heat storage tank 20 can be kept almost constant.

Therefore, according to the second embodiment of the present invention, by using the opposed oscillating flow type heat pipe 2, the calorie of the exhaust gas by the burner 11 can be reused, and the heat medium in the heat storage tank 20 can be reused. The temperature of 21 can be kept almost constant. Further, since the burner 11 is not directly controlled as in the related art, the temperature in the heat storage tank 20 can be controlled while the can water is continuously heated in the can 13.
Therefore, the overall efficiency is higher than before. In addition,
In the first and second examples, the control target of the control box 5 is the vibrator 2
However, for example, a thermo sensor 6 is provided in the flue 14 to detect the temperature of the exhaust gas so that the temperature of the exhaust gas of the burner 11 does not become too high, and the temperature of the exhaust gas is sensed. The burner 11 may be controlled.

The control box 5 has the boiler 1
The control box 5 may stop the vibration of the vibrator 2d by sending a signal indicating that the heating by 0 has stopped. By stopping the vibrator 2d,
The opposed oscillating flow type heat pipe 2 is in a state of hardly transmitting heat, and the control box 5 is connected to the vibrator 2d.
By stopping the vibration of the flue gas, the overall efficiency is increased, and normally, when the boiler 10 stops, the flue 1
4 is lower than the temperature of the can water or the heat storage tank 20, and the heat of the can water or the like is released to the flue 14. However, the stop of the vibrator 2d causes the counter-oscillating flow heat Since the heat conduction of the pipe 2 is cut off, this wasteful heat loss can be prevented. Further, the heat receiving unit 3
The configuration of the heat radiating section 4 may be the same as that of the first example.

Next, a heat conduction device and a boiler 10 as a third example of the present invention will be described below. In the boiler 10 shown in FIG. 5, the heat conduction device of the present invention does not conduct the exhaust heat into the can 13 as in the first example, but supplies water to the external heat exchange unit 17 for supplying hot water. The configuration is substantially the same as that of the boiler 10 of the first example except that the power is transmitted to the pipe 18b of the first example, and the same components as those of the first example are denoted by the same reference numerals and the description thereof will be omitted. Omitted. The hot water supply equipment 18 having the external heat exchange unit 17 includes a water supply pump 18a that sends water from a water supply tank (not shown) to the external heat exchange unit 17, a pipe 18b through which water sent from the water supply pump 18a passes, and an external heat source. The hot water supply pipe 18d is used to use the water warmed by the exchange unit 17, and a device (for example, including a heating device and a faucet 18c) that consumes hot water is installed at the tip thereof.

In the heat conduction device, the above-mentioned opposed oscillating flow type heat pipe 2 is used as a heat conducting member. The high temperature portion of the opposed oscillating flow type heat pipe 2 absorbs heat from the exhaust gas of the burner 11. The pipe 18 is connected to the heat receiving section 3 and the low temperature section.
A heat radiating section 4 for radiating heat to the water in b is provided. The heat receiving section 3 is installed in the flue 14, and the heat radiating section 4 is installed in the pipe 18b. A control box 5 for controlling the frequency and amplitude of the vibrator 2d by temperature is connected to the vibrator 2d provided inside the opposed vibrating flow heat pipe 2. In addition, a thermo sensor (not shown) is provided in the hot water supply pipe 18d to detect the temperature of hot water in the hot water supply pipe 18d. Then, the temperature detected by the thermo sensor is output to the control box 5 as a signal indicating the temperature by a signal output means (not shown).

The water supply pump 18a is provided with signal output means for outputting a signal indicating start / stop of water supply of the water supply pump 18a. The signal indicating the start and stop of water supply may be, for example, a signal that outputs a pulse signal at the start of water supply or at the time of water supply stop, or may be one of water supply and water supply stop. A high level signal may be continuously output, and in the other case, a low level signal may be continuously output. Control box 5
Is a well-known control having a CPU as an arithmetic processing unit, a storage device having a memory such as a RAM and a ROM connected to the CPU by a bus, and an interface for inputting and outputting signals between the CPU and an external device. The device is also
The control box 5 controls the start and stop of the vibration of the vibrator 2d of the heat conduction device in conjunction with the start and stop of the water supply in the water supply pump 18a, and also controls the heating based on the water temperature in the hot water supply pipe 18d. The frequency (amplitude) of the vibrator 2d is controlled.

Next, the operation of the heat conduction device when the boiler 10 in the third example is operating will be described. First, when hot water supply is started (for example, a valve for hot water is opened in a device that consumes hot water and a decrease in water pressure at the water supply pump 18a is detected by a sensor or the like), the water supply pump 1 is started.
8a operates. When the water supply pump 18a operates, a signal indicating the start of water supply is output from a signal output unit connected to the water supply pump 18a. The control box 5 to which this signal is input operates the vibrator 2d of the opposed oscillating flow heat pipe 2 in a high frequency Hi mode in synchronization with the start of water supply, and the opposed oscillating flow heat pipe 2 is almost From a state that does not conduct heat to a state that conducts heat with high thermal conductivity,
The water supplied to the external heat exchange unit 17 is preheated by the exhaust heat.

During the hot water supply in which the water supply pump 18a is operating, the vibrator 2d of the opposed oscillating flow heat pipe 2 is basically always operated to reuse the exhaust heat of the boiler 10. On the other hand, when the temperature of the hot water in the transfer pipe 18c does not reach a preset temperature reference value (for example, 70 ° C.), the burner 11 of the boiler 10 is set to a high combustion state, and the temperature of the hot water is previously set. If the set temperature reference value has been reached, the burner 11 of the boiler 10 is set to a low combustion state. Thus, during hot water supply, the water in the pipe 18b supplied to the external heat exchange unit 17 is always preheated by the exhaust heat, and the temperature is controlled on the burner 11 side. Accordingly, the amount of heat from the can water for maintaining the set temperature reference value can be reduced. That is, the burner 11 has a relatively low combustion state for a long time, and energy saving is realized.

Further, when the hot water supply is stopped (for example, when a valve for hot water is closed in all devices consuming hot water and an increase in water pressure is detected by a sensor or the like in the water supply pump 18a), the water supply pump 18a is stopped. Also stop. When the water supply pump 18a stops, a signal indicating water supply stop is output from the signal output means connected to the water supply pump 18a. When the temperature of the hot water in the hot water supply pipe 18d has reached the set temperature reference value, the control box 5 sends a signal from the thermo sensor in the hot water supply pipe 18d indicating that the temperature of the hot water is higher than the set temperature reference value. And water supply pump 1
When a signal indicating that the water supply pump 18a has stopped is input from the signal output means 8a, the control box 5 stops the vibrator 2d of the opposed oscillating flow heat pipe 2 in conjunction with the stop of water supply. Then, the counter-oscillating flow heat pipe 2 is hardly heat-conductive, and the preheating of the water supplied to the external heat exchange unit 17 is stopped.

On the other hand, even when a signal indicating the stop of the water supply pump 18a is output from the signal output means of the water supply pump 18a, a signal indicating that the temperature of the hot water is lower than the set temperature reference value from the thermo sensor in the hot water supply pipe 18d. Is output, the exciter 2d of the opposed oscillatory flow heat pipe 2 is not stopped, and the exciter 2d
Vibrates. Thereby, the water in the pipe 18b is heated, and the hot water supply pipe 18d connected to the pipe 18b is heated.
Is also warmed, the temperature of the hot water in the hot water supply pipe 18d gradually rises, and reaches the set temperature reference value. Then, when a signal indicating that the temperature has reached the set temperature reference value is output from the thermosensor, the control box 5 stops the vibrator 2d of the opposed oscillating flow heat pipe 2. Further, when the water pump 18a is operated in a state where the vibrator 2d of the opposed oscillating flow type heat pipe 2 is stopped or vibrates in the LOW mode as described above, the signal output unit outputs the signal. A signal indicating that the water supply pump 18a has been operated is output to the control box 5, and the control box 5 operates the vibrator 2d of the opposed oscillating flow heat pipe 2 in the Hi mode.

Therefore, according to the third embodiment of the present invention, by using the opposed oscillating flow type heat pipe 2, the calorific value of the exhaust gas by the burner 11 can be reused and the heat source of the hot water supply equipment 18 can be used. External heat exchange section 17
And a hot water supply system 18 with high overall heat transfer efficiency can be realized. While the hot water supply is stopped and the water supply to the external heat exchange unit 17 is stopped, the external heat exchange unit 1
The water supplied to the water 7 is not heated, and it is possible to prevent the water from being heated more than necessary before the external exchange unit 17 when the water supply is stopped. The heat receiving section 3 and the heat radiating section 4
May be the same as that of the first example.

Next, a heat conduction device and a power generation device as a fourth example of the present invention will be described below. The power generator 30 shown in FIG. 6 mixes fuel gas and compressed air,
A combustion chamber 31 for combustion, and a turbine 32 for obtaining a rotational force from combustion energy released from the combustion chamber 31
(Gas turbine), a compressor 33 for compressing air by a rotational force of the turbine 32, and a generator 34 (power generation unit) for generating electricity, and the air compressed by the compressor 33 is generated by heat of exhaust gas. A recuperator 35 as a heat exchanger for heating, a flue 36 (exhaust system) for inducing and discharging the exhaust gas to the outside, and a compressor 33
High-performance filter 3 for purifying air taken in
7 is provided. Further, the power generator 30 has a heat storage tank for storing heat energy of exhaust gas discharged from the combustion chamber 31 in order to recover radiation and exhaust gas loss that accounts for about one third of the entire fuel. 20 (a heat storage unit) is provided, and the heat transfer device for transmitting the heat energy of the exhaust gas to the heat storage tank 20 is provided. The electric power obtained from the generator 34 is supplied to the AC / DC converter 4.
0, the storage battery 41 is charged, or is used as a commercial power supply 44 via an AC / DC converter 40, an AC / DC inverter 42, and a transformer 43. In addition, storage battery 4
1. Circuit breaker 4 for switching to commercial power supply 44
5 is provided. Further, the heat energy of the heat storage tank 20 is used as a heat supply device 50 for supplying hot water or heating.

Next, the operation of the heat conduction device when the power generation device 30 in the fourth example is operating will be described. First, a valve of a pipe through which the fuel gas passes is opened, and the fuel gas flows into the combustion chamber 31. The fuel gas is ignited by an unillustrated ignition plug or the like in the combustion chamber 31 to start combustion and discharge exhaust gas to the outside of the combustion chamber 31. The exhaust gas turns the blades of the turbine 32 and is discharged outside through the recuperator 35 and the flue 36. Here, when the starter such as the ignition plug or the like is turned on, the power sources of the vibrator 2d, the thermosensor 6, and the control box 5 are also turned on. Then, the temperature of the heat medium 21 in the heat storage tank 20 is sensed by the thermosensor 6, and information is transmitted from a transmission unit provided in the thermosensor 6 to a reception unit of the control box 5. Here, the temperature of the heat medium 21 in the heat storage tank 20 is still normal temperature (for example, 20 ° C.), and the temperature of the heat medium 21 is lower than the preset heat medium set temperature in the heat storage tank 20 (for example, (67 ° C.), the control box 5 gives a command to the vibrator 2d to set the vibrator 2d to the Hi mode, and vibrates the vibrator 2d at high speed.

As the vibrator 2d vibrates at a high speed, the heat conductivity of the opposed oscillating flow heat pipe 2 increases, and a large amount of heat is transmitted to the heat medium 21 in the heat storage tank 20. At this time, since a large amount of heat is radiated from the heat radiating section 4, the temperature of the heat medium 21 in the heat storage tank 20 rapidly rises. Eventually, when the temperature of the heat medium 21 reaches the lower limit of the heat medium set temperature, the control box 5
An instruction is given to the controller d to set the vibrator 2d to the low mode, and the vibrator 2d is vibrated at a low speed. The shaker 2d
Vibrates at a low speed, the thermal conductivity of the opposed oscillating flow heat pipe 2 decreases, and a relatively small amount of heat is conducted to the heat medium 21 in the heat storage tank 20. Since a small amount of heat is radiated from the heat radiating section 4, the heat medium 2 in the heat storage tank 20
The temperature rise of 1 becomes gentler than when the vibrator 2d is in the Hi mode.

Thereafter, the temperature of the heat medium 21 gradually rises, and eventually the upper limit value of the heat medium set temperature (for example, 7.
When the temperature exceeds 3 ° C.), the control box 5
An instruction is given to d to forcibly stop the vibrator 2d, and the vibrator 2d is stopped. When the vibrator 2d stops, the opposed oscillating flow type heat pipe 2 becomes
The heat conduction from the heat receiving section 3 is almost cut off. The temperature of the heat medium 21 in the heat storage tank 20 in which the heat conduction has been cut off does not rise, and then gradually starts to fall.
The temperature of the heat medium 21 decreases rapidly, and reaches a predetermined temperature within the range of the heat medium set temperature (for example, 68.5).
C) or less, the control box 5
d, a command to start the vibrator 2d again in the low mode is issued, and the vibrator 2d starts vibrating at a low speed. By starting the vibrator 2d, the heat transfer function of the opposed oscillating flow heat pipe 2 is also restored, and a small amount of heat is transmitted from the heat receiving unit 3 to the heat radiating unit 4. Then, the temperature of the heat medium 21 in the heat storage tank 20 also starts to gradually rise again. However, when the operating load is large and the temperature of the heat medium further drops and falls below the lower limit value (for example, 67 ° C.) of the heat medium set temperature, for example, becomes 60 ° C. or less, a command to set the Hi mode is given again, and The same operation as that at the time of start is performed. By repeating the above operation, the temperature of the heat medium 21 in the heat storage tank 20 can be kept almost constant.

Therefore, according to the fourth embodiment of the present invention, by using the opposed oscillating flow heat pipe 2, the combustion energy released from the combustion chamber 31 of the gas turbine can be reused. The temperature of the heat medium 21 in the heat storage tank 20 can be kept almost constant. In the fourth example, the control target of the control box 5 is the vibrator 2
However, for example, a thermo sensor is provided in the flue 36 to detect the temperature of the exhaust gas so that the temperature of the exhaust gas ejected from the combustion chamber 31 does not become too high. The opening and closing of the fuel supply valve of the power generator 30 may be controlled via the power generator 30. Further, the configuration of the heat receiving unit 3 and the heat radiating unit 4 may be the same as that of the first example. Further, the place where the heat radiating unit 4 is installed is not limited to the inside of the heat storage tank 20. For example, instead of the external heat exchanging unit as in the third example, the heat radiating unit 4 may be installed in a pipe of a hot water supply facility having a heat storage layer or a hot water storage type boiler. Is also good. In this case, the water supplied by the exhaust heat of the turbine 32 is heated by using the opposed oscillating flow heat pipe 2 to generate hot water (an auxiliary burner may be used if necessary). As in the third example, the start / stop of the vibration of the vibrator of the heat conducting member may be controlled in conjunction with the start / stop of the water supply to the hot water supply equipment.

A floor heater 60 as a heating device using a heat conducting device according to a fifth embodiment of the present invention will be described below. The floor heating 60 shown in FIG.
And the counter-oscillating flow heat pipe 2 extending in a meandering manner inside the floor material 61, and a control box 5 for controlling a vibrator 2 d inside the counter-oscillating flow heat pipe 2.
And a thermo sensor (not shown) installed on the indoor side of the floor material 61 and a heat source 62 for supplying heat to the opposed oscillating flow heat pipe 2. Next, a mechanism for transmitting heat from the heat source 62 to the floor material 61 will be described. First,
When the main power of the floor heating 60 is turned on, the power of the heat source 62 and the power of the vibrator 2d, the thermosensor, and the control box 5 are also turned on in conjunction with each other. Then, the indoor temperature is sensed by the thermo sensor, and information is transmitted from a transmitting unit provided in the thermo sensor to a receiving unit of the control box 5.

Here, the room temperature is still room temperature (for example, 15
° C), and assuming that the room temperature does not reach the lower limit of the preset temperature (for example, 24 ° C), the control box 5 sends the vibrator 2d to the vibrator 2d.
A command to set d to the Hi mode is given, and the vibrator 2d is vibrated at a high speed. When the vibrator 2d vibrates at a high speed, the thermal conductivity of the counter-oscillating flow heat pipe 2 increases, and a large amount of heat is transmitted to the floor material 61. At this time, since a large amount of heat is radiated from the floor material 61, the room temperature rapidly rises. Eventually, when the room temperature reaches the lower limit of the set temperature, the control box 5 gives a command to the vibrator 2d to set the vibrator 2d to the low mode,
The vibrator 2d is vibrated at a low speed. When the vibrator 2d vibrates at a low speed, the heat conductivity of the opposed oscillating flow heat pipe 2 becomes low, and a relatively small amount of heat is released from the floor material 61.
To conduct. Since a small amount of heat is radiated from the floor material 61, the room temperature rise becomes gentler than when the vibrator 2d is in the Hi mode.

Thereafter, the room temperature gradually rises, and when the room temperature exceeds the upper limit of the set temperature (for example, 26 ° C.), the control box 5 forces the vibrator 2d to the vibrator 2d. Is given to the exciter 2
Stop d. When the vibrator 2d stops, the opposed oscillating flow heat pipe 2 substantially blocks heat conduction from the heat source 62. When the heat conduction is interrupted, the room temperature does not rise, but gradually starts to fall. When the room temperature falls and falls below a predetermined temperature (for example, 24.5 ° C.) within the set temperature range, the control box 5 instructs the vibrator 2d to lower the vibrator 2d again. Command to start in mode,
The vibrator 2d starts vibrating at a low speed. By starting the vibrator 2d, the heat transfer function of the counter-oscillating flow heat pipe 2 is also restarted, and a small amount of heat is supplied from the heat source 62 to the floor material 61.
Conducted to. Then, the room temperature also starts to rise gradually again. However, when the air temperature is considerably low, the indoor temperature further falls, and falls below the lower limit value of the indoor set temperature (for example, 24 ° C.), for example, becomes 20 ° C. or less, a command to set the Hi mode is given again, and the operation is started. The same operation as at the start is performed. By repeating the above operation, the room temperature can be kept substantially constant.

Therefore, according to the fifth embodiment of the present invention, the use of the opposed oscillating flow heat pipe 2 makes it possible to keep the room temperature substantially constant. The method of using the opposed oscillating flow type heat pipe 2 is not limited to the floor heating described above, and is used as a various heating device or a snow melting device embedded in a road such as a heavy snowfall area to melt snow accumulated on the road. You may. In cases other than floor heating, for example, the heat radiating portion of the opposed oscillating flow heat pipe 2 may be formed into a panel heater or an oil heater. Further, the configuration of the heat receiving unit 3 may be the same as that of the first example. Further, the set temperature of the room temperature in the fifth example may be freely selected manually. Even if the set temperature changes, the above operation is reproduced, so that the room temperature can be kept almost constant at the set temperature.

In FIG. 7, the temperature of the heat source 62 is
If, for example, the room temperature when temperature control is not performed is 30 ° C. and, for example, cold water or well water of about 5 ° C. is used as the cold heat source 62, the above-described floor heating system can be used for cooling. . Further, in the cooling and heating system, the opposed oscillating flow type heat pipe 2 may be used for heat transfer between the outdoor unit and the indoor unit. That is, the outdoor unit and the indoor unit are connected using the opposed oscillating flow heat pipe 2 and the outdoor unit is used as a heat source or a cold heat source,
The heat may be transported to the indoor unit by using the opposed oscillating flow heat pipe 2. In the case of such a configuration, there is no problem in heat transfer in the vertical direction as in the case where a conventional two-phase heat pipe is applied to a cooling and heating system of a building. For example, when an outdoor unit is installed on the upper side of a building using a conventional heat pipe and heating is performed on the lower floor side of the building, the heated and vaporized gas in the heat pipe must not fall down. As a result, heat transfer may be hindered, or conversely, if an outdoor unit is installed below the building and cooling is performed on the upper floor of the building, the liquid that has been cooled and condensed in the heat pipe rises upward. Not climbing may hinder heat transport. On the other hand,
In the opposed oscillating flow type heat pipe 2, since the inside thereof is almost always filled with the liquid, heat can be transported almost independently of the vertical direction. Therefore, the above-described cooling and heating system can be suitably applied to a middle-to-high-rise building. The heat source (cold heat source)
The present invention is not limited to a general outdoor unit, and various types of heat storage tanks (a type that produces ice as a cold heat source), spring water, well water, various types of exhaust heat, geothermal heat, and hot springs may be used. Then, even if the temperature cannot be controlled on the heat source side, the temperature can be controlled by controlling the amount of heat transported according to the state of vibration of the opposed oscillating flow heat pipe 2 as described above. In addition, even when a heat source capable of controlling the temperature is used, energy loss can be reduced by controlling the vibration of the opposed oscillating flow heat pipe 2 in accordance with the turning on and off of the heat source.

In the first to fifth examples, the control of the vibrator 2d is limited to the three patterns of the Hi mode, the Low mode, and the stop. However, the thermal conductivity of the opposed oscillating flow heat pipe 2 corresponds to the vibration. Therefore, it is also possible to increase the number of control steps and control according to the load of hot water supply or heating, or appropriately according to the temperature.
