2. Description of the Related Art As a construction technique of a solar cell module for performing photovoltaic power generation, as disclosed in Japanese Patent Application Laid-Open No. 11-159071, a vertical rail and a horizontal rail made of an extruded aluminum material are attached to a base plate. A general method is to install a solar cell module on the top and fix it to the rail with a holding bracket. The vertical rail is a rail whose longitudinal direction is the direction from the ridge to the eave, and the horizontal rail is a rail whose longitudinal direction is a direction perpendicular to the longitudinal direction of the vertical rail.

[0003] Japanese Patent Application Laid-Open No. Hei 11-3 has been devised for the purpose of generating solar power and utilizing solar thermal energy.
There is a photothermal hybrid module disclosed in Japanese Patent No. 30525. This is also referred to as a photovoltaic cogeneration module, a module that has both functions of solar power generation, which uses solar cells to generate electricity from sunlight, and solar heat collection, which collects and collects solar heat with a heat medium. It is. This module is assembled with parts and members as shown in FIG. 11, and the main part has a structure in which a heat collecting plate through which a heat medium flows is adhered to the back surface of the solar cell module using an adhesive.

A photothermal hybrid panel, which is a structural unit of a photothermal hybrid module, is disclosed in
There is one disclosed in Japanese Patent Publication No. 103087. As shown in FIG. 12, this photothermal hybrid panel includes a front glass substrate 21-an upper resin layer 22 from the front side receiving sunlight.
-Solar cell 23-lower resin layer 24-heat collecting panel 25
These members are laminated in this order. By making the thickness of the upper resin layer 22 larger than the thickness of the lower resin layer 24, the heat radiation from the solar battery cells 23 can be reduced by passing through the lower resin layer 24 more than the heat radiation passing through the upper resin layer 22. The calorific value is made larger. Thereby, the heat collecting efficiency of the heat collecting panel 25 attached to the back surface side of the solar cell 23 is improved, and the heat collecting panel 25 can be more effectively used as a heat source such as hot water supply and heating. This photothermal hybrid panel also has a main part in which a heat collecting panel through which a heat medium flows is arranged on the back of the solar cell.

Is arranged, it is necessary to replace both the solar cell and the heat collecting plate when the solar cell or the heat collecting plate becomes defective, and the maintainability is very poor. That is, in general, depending on the type of the heat medium circulating on the heat collecting plate side, the life of the heat collecting plate is often shorter than that of the solar cell module due to corrosion of the heat medium circulating pipe or the like. It is considered that the necessity of replacing the heat collecting plate and the heat medium distribution pipe often arises first, and even in the case of such a defect of only the heat collecting plate, the solar cell module part is also replaced together with the heat collecting plate. There is a need,
In this respect, maintainability is very poor. (4) In addition to the electrical connection work for the solar cell modules, it is necessary to carry out piping work to connect the inlet and outlet of the heat medium distribution pipe of each heat collecting plate, and there are many places for this piping work, which leads to construction costs. Greatly increase.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is implemented, for example, as follows. One or more heat transfer tubes are arranged inside a solar cell mounting member for fixing the solar cell module on the roof, and a heat medium flows inside the heat transfer tubes. Then, the solar cell mounting member according to the present invention is obtained. Then, in a state where the solar cell module is fixed on the roof by the solar cell mounting member, a heat medium flows into the heat transfer tube, and the heat medium collects and recovers solar heat energy. On the other hand, in the solar cell module, solar power is generated by a solar cell. In such a form, the solar cell mounting member according to the present invention is obtained and used.

Hereinafter, the operation and effect of the present invention will be mainly described.

As described above, the solar cell mounting member according to the present invention is a solar cell mounting member for fixing a solar cell module on a roof, in which one or more heat transfer tubes are disposed. It is characterized in that a heat medium is flowed in a heat pipe to collect solar thermal energy (first example).
invention).

When the solar cell module is fixed on a roof by the solar cell mounting member, and a heat medium flows through the heat transfer tube, solar heat energy can be collected and recovered by the heat medium. In addition, solar power generation by a solar cell can be performed by the solar cell module. In other words, the solar power cogeneration module has both functions of solar power generation by the solar cell and solar heat collection by the heat medium, and functions and functions as such a module. The collection of solar heat by the heat medium is performed by conducting the solar heat received by the upper surface of the solar cell mounting member and the solar cell module to the heat transfer tube and further to the heat medium inside the heat transfer tube.

Such a module has a very small number of parts and a very simple structure, and can be manufactured and constructed extremely easily, and is extremely excellent in workability. The cost is very low.

Further, since the heat transfer pipe (solar heat collecting pipe) for circulating the heat medium and collecting the solar heat is arranged inside the solar cell mounting member, the solar cell and the solar collecting pipe. (Heat-transfer tube) and the insulation is extremely high and excellent, and the insulation is hardly deteriorated.

Further, since the water pipe for heat collection (heat transfer pipe) for solar heat collection is not arranged on the back of the solar cell module but is arranged inside the solar cell mounting member for collecting heat of the solar heat, the solar system is structured such that When the battery or the solar heat collecting water pipe becomes defective, it is not necessary to replace both of them, and only the defective one has to be replaced. In other words, it is considered that the necessity of replacing the solar heat collecting water pipe (heat transfer pipe) often occurs before the solar cell. In such a case, if only the solar heat collecting water pipe is replaced, In this respect, maintainability is extremely excellent.

Therefore, according to the solar cell mounting member according to the present invention, the solar power / heat supply module having both functions of solar power generation by the solar cell and solar heat collection by the heat medium has an extremely small number of parts. The structure is very simple and extremely easy to construct, and the insulation between the solar cell and the water collection tube for heat collection (heat transfer tube) is hardly deteriorated. Will be able to In other words, the solar cell cogeneration module with extremely excellent insulation and maintainability between the solar cell and the solar heat collection water pipe as described above, with an extremely small number of parts,
In addition, it is possible to obtain remarkably good workability.

FIG. 1 shows an example of a main part of a solar / electric power supply module comprising a solar cell mounting member 2 according to the present invention and a solar cell module fixed thereby. In this example, as shown in FIG. 1, the inside (on the bottom) of the vertical rail 5, which is one component of the solar cell mounting member, is
The heat transfer tubes 4 are arranged, and the heat transfer tubes 4 are pressed and fixed by the fixing bracket 6, the solar cell module holding plate 3, and the screws via the surrounding heat transfer tube support members. The end of the solar cell module 1 is sandwiched by packing between the outer flange on the upper part of the vertical rail 5 and the solar cell module pressing plate 3 via packing, and the solar cell module 1
Has been fixed. In FIG. 1, reference numeral 7 denotes a heat insulating material.

A heat medium flows through the heat transfer tube 4. Then, the solar heat received by the solar cell module holding plate 3 and the solar cell module 1 is transmitted to the heat medium inside the heat transfer tube via the heat transfer tube 4, and is collected and recovered by the heat medium. On the other hand, the solar cell module 1 performs solar power generation using the solar cell.

Therefore, the module shown in FIG. 1 functions and functions as a solar / electric power supply module having both functions of solar power generation by a solar cell and solar heat collection by a heat medium. Further, as can be seen from FIG. 1, it is possible to obtain an extremely small number of parts and with extremely good workability, and in use, the insulation between the solar cell and the heat transfer tube 4 is hardly deteriorated. When the solar cell or the heat transfer tube 4 becomes defective, only the defective one needs to be replaced, which is extremely excellent in maintainability.

FIG. 7 shows an example of an assembling diagram of a photovoltaic / cogeneration module using the solar cell mounting member according to the present invention. In this example, SU is used as a heat transfer tube inside the vertical rail 5 which is a component of the solar cell mounting member.
An S (stainless steel) or Ti tube is provided. It can be seen from FIG. 7 that the solar power cogeneration module can be assembled with an extremely small number of parts and with extremely high workability. Further, it can be seen that when the solar cell or the heat transfer tube becomes defective, only the defective one needs to be replaced, which is extremely excellent in maintainability.

In FIG. 7, an aluminum heat collecting plate is provided as a separate component on the back surface of the solar cell module. However, as shown in FIG. Wings may be provided.

Further, a configuration in which a ventilation hole is provided on the side of the solar cell module mounting member is also effective because the heat of the air heated on the back surface of the solar cell module can be recovered. In this case, it is preferable to provide two ventilation holes on the ridge side and the eave side in the longitudinal direction of the solar cell module mounting member. With this configuration, the air warmed on the back surface of the solar cell module enters the solar cell module mounting member from the ventilation hole provided on the ridge side, and is cooled by the heat transfer tube and provided on the ridge side. The pores are discharged to the outside of the solar cell module mounting member, and the heat of the air warmed on the back surface of the solar cell module can also be recovered.

Regarding the size of the solar cell mounting member according to the present invention, the total area [S1] of the surface portion of the solar cell mounting member exposed to sunlight is the total area of the entire solar cell module that performs photovoltaic power generation. [S2] is preferably 5% or more (second invention). This is because the amount of the photovoltaic power generation and the amount of the solar heat energy recovery are well-balanced, so that a sufficient amount of electricity and a sufficient amount of heat can be obtained. That is, S
If the ratio of S1 to 2 is less than 5%, the amount of electricity obtained is large and sufficient, but the amount of heat obtained is small and tends to be insufficient or insufficient. However, S
If the ratio of S1 to S2 is too large, the amount of heat obtained is large and sufficient, but the amount of electricity obtained is small and insufficient or insufficient.
Should not be too large,
For this purpose, it is desirable that the ratio of S1 to S2 be 15% or less. In addition, the area of the surface portion of the solar cell mounting member exposed to sunlight refers to the area of the surface portion of the solar cell mounting member where the heat transfer tube is disposed, which is exposed to sunlight. In addition, the area where the heat transfer tube is not arranged is not included in the area. The total area of the entire solar cell module that performs solar power generation corresponds to the total surface area of the solar cell.

The above area will be specifically described below with reference to the drawings. FIG. 2 is a side sectional view showing an example of a main part of a solar / electric power supply module comprising a solar cell mounting member 2 according to the present invention and a solar cell module 1 fixed thereby. FIG. 3 is a top view of a main part of the module. In this example, three heat transfer tubes 4 are arranged inside a vertical rail (a rail in which the longitudinal direction of the rail is from the ridge to the eave).

The width of the solar cell module holding plate 3 above the vertical rail 5 is P2, the effective width of one of the solar cell modules 1 (effective width in the direction perpendicular to the vertical rail) is P1, and the solar cell module 1 is The length (length from the ridge to the eaves) of the solar cell module is R1, and the width of the solar cell module holding plate above the horizontal rail (the rail in which the longitudinal direction of the rail is perpendicular to the longitudinal direction of the vertical rail) is R2. I do. The number of solar cell modules 1 in the direction from the building to the eaves is M, and the number of solar cell modules 1 in the direction perpendicular to this is N.

Then, the sum S1 of the surface area of the solar cell mounting member exposed to sunlight is [(R1
× M) + (R2 × (M-1))] × P2 × (N + 1),
The total area S2 of the entire solar cell module is R1 × P1 ×
M × N. Therefore, making the total area of the surface portion of the solar cell mounting member exposed to sunlight equal to or more than 5% of the total area of the entire solar cell module is 100 × S1 / S2 = 100 × [( R1 × M) +
(R2 × (M-1))] × P2 × (N + 1) / (R1 ×
The value (%) of (P1 × M × N) is to be 5% or more. The effective width of one solar cell module 1 is the sum of the widths of the solar cells included in one solar cell module 1.

There is no obstacle in the heat transfer tube arrangement in the heat transfer tube disposition portion inside the solar cell attachment member, and the heat transfer tubes are integrally disposed inside the solar cell attachment member without being joined. Is desirable (third invention). In this case, since the heat transfer tube located inside the solar cell mounting member does not require a pipe connection using a joint, the number of man-hours required for on-site construction is reduced and the number of piping members is reduced. This is because the cost for members and construction can be reduced, and the man-hours required for maintenance can be reduced, so that the maintainability can be improved and the costs for maintenance can be reduced.

FIG. 7 shows an example of the arrangement of the heat transfer tubes as described above.
In this example, the heat transfer tube disposition portion inside the vertical rail 5, which is one component of the solar cell mounting member, has no obstacle in the heat transfer tube disposition such as a step or a bend, and is in the longitudinal direction of the rail. Be honest. Therefore, an integral straight heat transfer tube can be easily arranged inside the vertical rail 5, and therefore, such a heat transfer tube is arranged.

It is preferable that the heat transfer tube located inside the solar cell mounting member is a seamless heat transfer tube (a fourth invention). In this case, the heat transfer tube located inside the solar cell mounting member does not require a pipe connection by a joint or welding, so that the number of man-hours for on-site construction is reduced, and since there is no seam, the reliability of the piping is improved. In addition, the number of man-hours for maintenance is reduced, and the maintainability is improved. In the example shown in FIG. 7, the above-described seamless heat transfer tubes are arranged.

It is preferable that the heat transfer tube disposed inside the solar cell mounting member is pressed against the upper portion of the solar cell mounting member (fifth invention).
By doing so, the heat transfer from the solar cell mounting member to the heat transfer tube, that is, the heat transfer efficiency (the amount of heat transfer per unit time) is improved, and the solar heat recovery efficiency (the amount of heat recovered per unit time) is improved. That is because That is, since the upper surface of the upper portion of the solar cell mounting member is heated by directly receiving sunlight, the temperature increases, and accordingly, the lower surface of the upper portion of the solar cell mounting member also increases in temperature. When the heat transfer tube is pressed (contacted) to the upper part of the solar cell, heat transfer from the upper portion of the solar cell mounting member to the heat transfer tube occurs through the contact portion between the two, and the heat transfer tube transfers from the solar cell mounting member. This is because the efficiency of heat transfer to the heat pipe is improved, and the efficiency of collecting solar heat by the heat medium in the heat transfer pipe is improved. At this time, when the upper part of the solar cell mounting member is in strong contact with the heat transfer tube, the efficiency of heat transfer from the solar cell mounting member to the heat transfer tube is improved. In addition, the larger the area of the contact portion between the upper part of the solar cell mounting member and the heat transfer tube, the higher the efficiency of heat transfer from the solar cell mounting member to the heat transfer tube. The upper part of the solar cell mounting member has a function of fixing the solar cell module, a function of holding down the heat transfer tube, and a function of receiving solar heat and transmitting it to the heat transfer tube.

When the heat transfer tube is pressed on the upper part of the solar cell mounting member as described above, a thin film of silicon grease, silicon resin, polyethylene or the like may be interposed therebetween, and it is more preferable to do so. In this case, the interposed object can reduce the thermal resistance of the contact portion with respect to the heat input from the cover (the upper part of the solar cell mounting member), and improve the heat collection efficiency.

It is preferable that the upper portion of the solar cell mounting member has a concave portion on the lower surface thereof which comes into contact with the outer peripheral surface of the heat transfer tube, and the outer peripheral surface of the heat transfer tube is brought into close contact with this concave portion (sixth embodiment). invention). In this case, since the area of the contact portion between the lower surface of the upper portion of the solar cell mounting member and the outer peripheral surface of the heat transfer tube increases, the heat transfer efficiency from the solar cell mounting member to the heat transfer tube (the amount of heat transfer per unit time) This is because the degree of improvement is increased, and the solar heat recovery efficiency (the amount of heat recovered per unit time) by the heat medium in the heat transfer tube is greatly improved. At this time, a thin film of silicon grease, silicone resin, polyethylene or the like is interposed between the lower surface of the upper portion of the solar cell mounting member and the outer peripheral surface of the heat transfer tube, and the lower surface of the upper portion of the solar cell mounting member and the heat transfer tube are interposed therebetween. May be brought into close contact with the outer peripheral surface of the device, and it is rather desirable to do so. In this case, the interposed object eliminates the air layer in the gap between the heat transfer tube and the solar cell mounting member, thereby reducing the thermal resistance of the contact portion and improving the heat transfer efficiency. Further, it is possible to prevent corrosion that is likely to occur between dissimilar metals between the heat transfer tube and the solar cell mounting member.

FIGS. 15 to 24 show examples in which the outer peripheral surface of the heat transfer tube is brought into close contact with the upper concave portion of the solar cell mounting member as described above. In the example shown in FIG. 15, the heat transfer tube (heat recovery tube) is connected to the center portion (heat transfer tube) of the solar cell mounting member by using a module cover and two bolts (cover holding bolts) which are upper components of the solar cell mounting member. The module cover has a concave portion which comes into contact with the outer peripheral surface of the heat transfer tube, and the outer peripheral surface of the heat transfer tube is connected to the concave portion through a resin film having good heat conductivity. We adhere. The module cover is directly fixed to the heat transfer tube support with bolts, and the structure is reasonable.

In FIG. 16, the module cover has hooks so that the module cover can be fixed with one bolt. The hooks are used as fulcrums, and the heat transfer tubes are connected to the module cover by using the bolt fastening portion as a power point. The structure is fixed, and the structure is more rational than that shown in FIG. In addition, a space is provided inside the heat transfer tube support to reduce the mass of the heat transfer tube support. In the structure shown in FIG. 17, the hooking claw is located on the opposite side to the case of FIG. 16, that is, on the power point side, and the hooking claw is fixed as a fulcrum according to the principle of leverage.

In FIG. 18, two heat transfer tubes are arranged. Further, the heat collecting fins protrude downward from the heat transfer tube support portion into the solar cell module mounting member (inside the rail), and a plurality of ventilation holes are provided on the side of the solar cell module mounting member. In this case, when the air warmed on the back surface of the solar cell module enters the rail from the ventilation hole and flows through the rail, the heat of the air can be recovered by the heat collecting fins,
This can be transmitted to the heat transfer tube, and the solar heat recovery efficiency (heat recovery amount per unit time) can be improved. The adoption of such a structure in which the heat transfer tube is pressed against the upper part of the solar cell mounting member also has an advantage that a heat collecting fin that functions as described above can be provided.

In FIG. 19, the heat collecting fins protrude laterally into the rail from the side wall of the solar cell mounting member.

In the structure shown in FIG. 20, before the work for fixing the solar cell module on the roof, a heat transfer tube is attached to the module cover, and the module cover and the heat transfer tube are integrated. It is used at the time. In this case, the maintainability may be reduced, but there is an advantage that the number of construction parts is reduced.

In the arrangement shown in FIG. 21, two heat transfer tubes are arranged. In the structure shown in FIG. 22, the structure of the solar cell mounting member at the end of the solar cell module has a left-right asymmetric structure. FIG.
The height (thickness) of the solar cell mounting member is smaller than that shown in FIG.

In FIG. 24, the solar cell mounting member can be separated into a lower portion (a member mounted on the roof) A and an upper portion (a member for fixing the solar cell) B,
The connection between the lower part A and the upper part B is made by bolt connection. In this case, there is an advantage that the degree of freedom during construction is improved and the maintainability is improved. Such a structure can be adopted due to the adoption of the structure in which the heat transfer tube is pressed against the upper part of the solar cell mounting member.

Regarding the place where the heat transfer tube is pressed, the bottom or the side of the solar cell mounting member may be used instead of the upper part of the solar cell mounting member. When this pressed part is the bottom or side of the solar cell mounting member,
When the heat transfer tube placed inside the solar cell mounting member is pressed against the bottom or side of the solar cell mounting member, heat can be recovered by transferring heat from the solar cell mounting member to the heat transfer tube It is. However, in this case, compared to the case where the pressed part is the upper part of the solar cell mounting member, the distance from the upper part where the temperature is the highest in the solar cell mounting member is larger, and the solar heat recovery is performed. Efficiency (heat recovery per unit time) is reduced. On the other hand, when the pressing part is located at the upper part, the degree of improvement in the heat transfer efficiency (the amount of heat transfer per unit time) from the solar cell mounting member to the heat transfer tube is extremely large, and as a result, the efficiency of solar heat recovery is improved. The degree is remarkably large. From this point, it is desirable that the heat transfer tube be pressed at a location higher than the bottom or the side of the solar cell mounting member.

Further, instead of making the outer peripheral surface of the heat transfer tube adhere to the concave portion on the upper portion of the solar cell mounting member, a mold member having a concave portion in contact with the outer peripheral surface of the heat transfer tube is provided at the bottom of the solar cell mounting member. The outer peripheral surface of the heat transfer tube may be brought into close contact with the concave portion of the mold. In this case, the mold is heated by the solar heat, heat is transferred from the mold to the heat transfer tube, and the solar heat can be recovered. At this time, the larger the contact area between the mold member and the solar cell mounting member, the higher the heat transfer efficiency from the solar cell mounting member to the mold member, and the mold member and the solar cell mounting member are in strong contact. Improves the efficiency of heat transfer from the solar cell mounting member to the mold,
As a result, the efficiency of heat transfer from the solar cell mounting member to the heat transfer tube is improved.

FIG. 4 shows an example in which the above-described mold members are provided.
In this example, a mold member 8 made of aluminum or the like having a concave portion in contact with the outer peripheral surface of the heat transfer tube 4 is provided at the bottom of the vertical rail 5 which is a component of the solar cell mounting member. 4 is made to adhere closely. In FIG. 4, the heat transfer tube is pressed against the bottom of the solar cell mounting member. This pressing is performed by pressing the heat transfer tube 4 downward with the fixing metal fitting 6, the solar cell module pressing plate 3, and the screw via the surrounding die 8, whereby the die 8 is also attached to the solar cell mounting member. It is pressed against the bottom. In this case, the efficiency of heat transfer from the vertical rail 5 to the mold 8 is improved, and this mold 8
Then, heat transfer from the heat transfer tube 4 to the heat transfer tube 4 occurs, and heat transfer from the vertical rail 5 to the heat transfer tube also occurs, thereby improving the efficiency of solar heat recovery.

The above-mentioned mold may be manufactured by an extrusion method or the like separately from the solar cell mounting member, or a part in contact with the lower part of the heat transfer tube may be manufactured by the extrusion method or the like integrally with the solar cell mounting member. You may.

As described above, when the mold is provided at the bottom of the solar cell mounting member and the outer peripheral surface of the heat transfer tube is brought into close contact with the concave portion of the mold, the solar heat recovery efficiency (the amount of heat recovered per unit time) is reduced. improves. However, in this case, the contact point (pressing point) of the heat transfer tube has the highest temperature in the solar cell mounting member as compared with the case where the outer peripheral surface of the heat transfer tube is closely attached to the upper concave portion of the solar cell mounting member. The solar heat recovery efficiency is low due to the large distance from the upper part, which is higher. On the other hand, when the outer peripheral surface of the heat transfer tube is closely attached to the concave part on the upper part of the solar cell mounting member, the solar cell The degree of improvement in the efficiency of heat transfer (the amount of heat transfer per unit time) from the mounting member to the heat transfer tube is extremely large, and thus the degree of improvement in the efficiency of solar heat recovery is significantly increased, and the number of parts is reduced. From this point, it is preferable that the outer peripheral surface of the heat transfer tube be in close contact with the concave portion on the upper part of the solar cell mounting member, and it is desirable to do so.

It is preferable that an air layer formed by using a material that transmits sunlight as at least a part of the material is provided on the solar cell mounting member (seventh invention). This is because solar heat energy incident from above the solar cell mounting member can be effectively used, and the amount of heat recovered from solar heat can be increased. That is, when there is no air layer as described above and the solar cell module holding plate above the solar cell mounting member is in direct contact with the atmosphere, when wind blows on the surface of the solar cell module holding plate, the solar cell module holding plate The temperature of the plate decreases due to convective heat transfer,
As a result, the temperature difference between the heat medium in the heat transfer tube to be heated and the solar cell module holding plate is reduced, and the amount of recovered heat of solar heat is reduced. On the other hand, when the air layer as described above is provided, it is possible to prevent the temperature of the solar cell module holding plate from lowering due to the convective heat transfer as described above. The temperature of the holding plate is increased, and the amount of solar heat recovered can be increased. Therefore, it is desirable to provide an air layer as described above. Here, the use of a material that transmits sunlight as at least a part of the constituent material forming the air layer increases the effect of the greenhouse,
This is to increase the amount of recovered heat of solar heat. From this point, it is further desirable that most or all of the constituent materials forming the air layer are made of a material that transmits sunlight.

FIGS. 5 and 2 show examples in which the air layer is provided as described above.
5 to 26. In FIG. 5, the solar cell module holding plate 3 on the upper part of the solar cell mounting member 2 is shown.
An air layer 9 as shown in FIG. The air layer 9 is formed using glass as a material that transmits sunlight at the upper part, and using opaque resin at the side walls. The thickness of the air layer 9, that is, the distance between the upper glass and the solar cell module holding plate 3 is several mm. The thickness of the air layer 9 is not limited to several mm. The material that transmits sunlight is not limited to glass, but may be any material that transmits sunlight, for example, a resin that transmits sunlight.

In FIG. 25, the module cover, which is the upper component of the solar cell mounting member, has a concave portion on its lower surface that comes into contact with the outer peripheral surface of the heat transfer tube. The air layer as described above is provided for the solar cell mounting member of the type in which the surfaces are in close contact. This air layer is formed using a transparent cover that transmits sunlight on the upper part and an opaque resin on the side wall.

In the module shown in FIG. 26, the module cover has a concave portion on the lower surface thereof which comes into contact with the outer peripheral surface of the heat transfer tube, and the outer peripheral surface of the heat transfer tube is brought into close contact with this concave portion. However, an air layer as described above is provided. However, there is a concave portion as shown in the figure on the upper surface of the module cover, and a transparent cover is provided above the concave portion to form an air layer. Further, the surface of the concave portion (the upper surface of the module cover) is subjected to selective absorbing plating or painting to form a layer having selective absorbing property (hereinafter, selective absorbing layer).

The selective absorption layer has a function of reducing radiation loss due to radiation, thereby increasing the temperature of the module cover, and further improving the solar heat recovery efficiency (heat recovery amount per unit time). In addition, the temperature of the heat medium in the heat transfer tube becomes higher. Specifically, 0.1
Assuming that 5 L (liter) / minute of water is flown and the length of the heat collecting tube is 3.3 m, the temperature of the water at the outlet of the heat transfer tube is about 1 ° C. on average compared with the case where there is no selective absorption layer. Can be higher. In addition, as the selective absorption layer, there are plating and painting as those generally used at low cost. These selective absorption layers are mainly composed of nickel (Ni) or chromium (Cr), and have a fine porous structure on the surface, which makes it difficult to emit geometrically-entered light. .
The function of the selective absorption layer is to absorb light very much (absorptance: 0.9 or more), but to emit very little (emissivity: ~)
(Less than 0.1) reduces the heat radiation loss due to radiation.

It is desirable that at least a part of the upper part of the solar cell mounting member is made of a material that transmits sunlight, and that an air layer is provided between the upper part of the solar cell mounting member and the heat transfer tube (the second layer). 8 inventions). In this way, the sunlight passes through the upper part of the solar cell mounting member and heats the inside of the solar cell mounting member, and the air layer acts as a greenhouse, so that the temperature of the heat transfer tube becomes higher. This is because the amount of solar heat recovered can be increased. Here, the use of a material that transmits sunlight for at least a part of the upper part of the solar cell mounting member increases the temperature of the heat transfer tube due to the above-described effect, and thus increases the amount of recovered heat of solar heat. It is to make it. From this point, it is further desirable that most or all of the solar cell mounting member is made of a material that transmits sunlight.

FIG. 6 shows an example in which an air layer as described above is provided. In this example, a material that transmits sunlight is used for the solar cell module holding plate 3 above the solar cell mounting member 2. The material that transmits the sunlight is not particularly limited, and may be any material having a sunlight-transmitting property, and for example, glass, a sunlight-permeable resin, or the like can be used. In FIG. 6, reference numeral 10 denotes an air space.

FIG. 14 shows an example of the present invention. In order that the module holding plate 3 does not impair the function of fixing the solar cell module, a sunlight-permeable heat insulating material 7 is attached so as to completely cover the module holding plate 3. Thereby, the module holding plate 3 and the sunlight-permeable heat insulating material 7
An air layer 9 can be formed therebetween.

A further preferred form of forming the air layer is a structure in which baffle plates are provided at intervals in the longitudinal direction of the air layer so as to prevent air in the air layer from moving in the longitudinal direction. That is, the inside of the air layer has a higher temperature on the solar cell mounting member side, that is, the bottom, compared to the top that is in contact with the outside via the sunlight permeable material, and the air in the air layer is warmed at the bottom. Convection by cooling at the top. When the convection becomes severe, the solar cell mounting member is eventually cooled, which is not preferable. Therefore, as a result of intensive studies on a method for suppressing this, it was found that cooling of the solar cell mounting member due to convection can be suppressed by providing the baffle plate in the longitudinal direction. The distance between the baffle plates is not particularly limited, but it is effective to set the distance to 400 mm or less.

Setting the thickness of the air layer to 4 mm or more is effective because the heat retaining property of the solar cell module mounting member can be maintained. The thickness of the air layer referred to here is the length of the longest portion of the air layer in the vertical direction. By setting this to 4 mm or more, the heat retention can be maintained. For example, when the heat transfer coefficient of the sunlight-permeable heat insulating material 7 is in the range of 14 to 28 W / m ² K, the air layer is set at 4 m.
m or more, the heat transfer coefficient of the air layer is 6.0 W
/ M ² K or less.

In order to reduce the heat loss, it is preferable that the inflow and outflow of the external air into and out of the air layer is as small as possible. However, holes are provided so that the water condensed in the air layer can be discharged to the outside. Is good.

In the present invention, the number of heat transfer tubes arranged inside the solar cell mounting member is not particularly limited, and the dimensions of the heat transfer tubes are not particularly limited. Compared with the case where many thinner heat transfer tubes are arranged, the latter is better in that it can increase the amount of recovered heat of solar heat, while the former is better in terms of workability and maintainability.

The shape of the heat transfer tube is not particularly limited, and various shapes can be used. For example, in addition to a circular cross-section (circular tube), a square cross-section or the like (square tube) Etc. can be used.

A filling member made of resin, metal or ceramic can be arranged in the heat transfer tube. When such a filling member is disposed in the heat transfer tube, there is an advantage that heat transmitted to the heat transfer tube can be efficiently transmitted to a heat medium such as water flowing in the heat transfer tube. FIGS. 27 to 28 show examples in which such a filling member is arranged in a heat transfer tube. In the one shown in FIG. 27, a resin ball is incorporated as a filling member in a square tube-shaped heat transfer tube. In the one shown in FIG. 28, a square tube-shaped heat transfer tube is in contact with the wall, top and bottom of the solar cell mounting member, and a resin ball is built in the heat transfer tube as a filling member.

The direction of the arrangement of the heat transfer tubes in the solar cell mounting member is not particularly limited, and may be a direction from the ridge to the eaves, a direction perpendicular to this direction, or both directions. They can be mixed. That is, a heat transfer tube can be arranged inside a vertical rail (a rail in which the longitudinal direction of the rail is from the ridge to the eave), and a horizontal rail (the longitudinal direction of the rail is perpendicular to the longitudinal direction of the vertical rail). The heat transfer tubes can be arranged inside the vertical rails and also inside the horizontal rails. However, when the heat transfer tube is arranged inside the horizontal rail, there is a possibility that the drainage property is deteriorated. Therefore, it is desirable to adopt the forced circulation type. By doing so, the problem of drainage is eliminated, and the drainage operation becomes unnecessary.
The forced circulation system circulates a heat medium through a heat transfer tube with a pump,
Heat exchange with tap water in a hot water tank to obtain hot water.

The constituent material of the heat transfer tube is not particularly limited, and various materials can be used. For example, stainless steel, Ti, copper, aluminum and the like can be used, but the heat conductivity is high. The higher the rate of solar heat recovery, the greater the amount of solar heat recovered, the greater the corrosion resistance, etc., and the longer the life is.Therefore, when selecting the constituent materials in consideration of these points, Good.

The constituent material of the solar cell mounting member is not particularly limited, and various materials can be used.
For example, stainless steel, aluminum, hard plastics and the like can be used, but the higher the thermal conductivity, the faster the solar heat recovery speed, the more the amount of solar heat recovered, the better the corrosion resistance and the like. Since there are advantages such as a longer life, it is preferable to select a constituent material in consideration of these points.

The heat medium flowing in the heat transfer tube is not particularly limited. For example, a heat medium such as ethylene glycol or propylene glycol or water such as tap water is used.
