Thus, when the cooling medium is supplied to the first cooling medium inlet and the second cooling medium inlet, the cooling medium can flow in the first spiral groove and the second spiral groove; the cooling medium can be contacted with the object to be cooled in the flowing process, and can absorb the heat on the surface of the object to be cooled; the cooling medium after absorbing heat can be discharged from the first cooling medium outlet and the second cooling medium outlet, in such a way that the object to be cooled can be cooled.
Referring to fig. 2, an embodiment of the present application provides a sensor cooling device, which includes the foregoing spiral cooler, and of course, may also include a spiral cooler obtained by combining an alternative scheme with the foregoing spiral cooler, and may also include a spiral cooler obtained by combining another alternative scheme not mentioned in the foregoing spiral cooler with the embodiment of the present application. In an embodiment of the application, the first cooling medium inlet 1031 is connected to a cooling medium supply (not shown), and the sensor 105 may be located in a first cooling medium receiving cavity, and the sensor wire 1051 may be located in a second cooling medium receiving cavity.
Therefore, by adopting the sensor cooling device provided by the embodiment of the application, the sensor in the first cooling object accommodating cavity and the sensor wire in the second cooling object accommodating cavity can be cooled.
Alternatively, the cooling medium may be water, air, or a dedicated coolant, or the like. When the cooling medium is air, the cooling medium may be supplied from an air compressor or the like, and of course, the cooling medium supply source may be a pressure air source. When the cooling medium is water or a dedicated coolant, the cooling medium may be supplied by a water pump or the like.
Alternatively, in the embodiment of the present application, a control valve or a filter valve may be provided between the first cooling medium inlet and the cooling medium supply source, and for example, the control valve may include a check valve, a pressure reducing valve, and the like, which are not described in detail herein.
Alternatively, in the embodiment of the present application, when the orifice 1072 is the second cooling medium inlet, the cooling medium may be introduced into the second spiral groove using the orifice 1072. The spiral cooler may not have a flow-distribution hole, and the second cooling medium inlet may be connected to the cooling medium supply source, so that the cooling medium may be introduced into the second spiral groove.
Alternatively, in an embodiment of the present application, the cooling medium may be air, and a pressure control valve may be connected between the first cooling medium inlet and the cooling medium supply source, the outlet pressure of the pressure control valve being 0.2 mpa.
In this way, the sensor and the sensor wires can be cooled.
Hereinafter, a method of using the spiral cooler will be briefly described by taking cooling of a vibration sensor (hereinafter referred to as vibration sensor) of a water feeding pump turbine of a thermal power plant as an example. The normal working temperature of the vibration sensor is minus 20-80 ℃, and the temperature of the vibration sensor lead wire are 140-180 ℃ after the conventional cooling scheme is used because the working environment of the vibration sensor is higher, so that the vibration sensor is difficult to work normally.
In practice, considering the cooling of the vibration sensor wire, a screw cooler having a first cooling object accommodating chamber and a second cooling object accommodating chamber is employed, and the screw cooler is provided in a bifurcated structure. It should be noted that a high temperature resistant vibration sensor wire may be used, and thus, only the sensor may be cooled.
Referring to fig. 7, the vibration sensor cooling apparatus includes: a shut-off valve 201, an isolation valve 202, a filter pressure reducing valve 203, and a screw cooler 204. The vibration sensor is placed in the first coolant receiving cavity of the screw cooler 204 and the vibration sensor wire is placed in the second coolant receiving cavity. The stop valve 201, the isolation valve 202, the filter pressure reducing valve 203 and the screw cooler 204 are connected by pipelines, and optionally, seamless instrument pipes can be selected as the pipelines. The cooling medium may be compressed air for instruments (pressure range of 0.5 to 0.7 mpa). The cooling medium enters the cooling device via a shut-off valve 201. Wherein, the outlet pressure of the filter pressure reducing valve may be set to 0.2MPa. After the cooling device is adopted, the surface temperature of the vibration sensor and the lead wire thereof can be controlled in the normal working temperature range.
In practice, the site may include various instruments to be cooled, and corresponding screw coolers may be provided for each instrument, so that each instrument may be cooled.
In addition, in a severe environment such as a thermal power plant, there are few technicians who cool a cooler dedicated to the arrangement of devices such as sensors. For more sophisticated automation systems, the automation system may generally be arranged in an air conditioning room to control the operating temperature of the respective instrument. Of course, for a precise automation system, some of the instruments which are arranged in a relatively scattered manner are difficult to be arranged in an air conditioning room, and some of the instruments which cannot be arranged in the air conditioning room can have poor heat dissipation. In addition, it is easy to understand that for high temperature occasions such as thermal power plants, it is difficult for technicians to arrange sensor sensitive elements or the like dispersed in the power generation equipment system in the air conditioning room. In the conventional cooling method of the cooling fan, since the temperature of the environment where the sensor sensitive element is located is high, it is difficult to discharge the heat of the sensor to the environment by cooling the sensor by the cooling fan, so that the temperature of the sensor is reduced.
In general, sensors and the like are typically associated with a device housing, the body of which may be exposed to the exterior of the housing. The spiral cooler provided by the embodiment of the application can be covered on a structure of the sensor and other instruments exposed to the outside of the shell, and can isolate the sensor and other instruments from an external high-temperature source by utilizing a cooling medium flowing in the spiral groove, so that the high-temperature source is prevented from transmitting heat to the sensor and other instruments; the cooling medium flowing in the spiral groove can be used for taking away heat on the surfaces of the instruments such as the sensor, and the temperature of the instruments such as the sensor can be reduced. Therefore, by adopting the spiral cooler provided by the embodiment of the application, the common sensor can be normally used in a high-temperature environment, so that the measurement accuracy of the common sensor in the high-temperature environment can be improved. In addition, by adopting the spiral cooler provided by the embodiment of the application, a common sensor can be selected in a high-temperature environment, and the purchase cost of instruments such as the sensor can be reduced.
It is noted that relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
