FIG. 7 is a schematic structural diagram of a temperature control unit according to an embodiment of the present invention. As shown in FIG. 7, the temperature control unit includes: a housing 71, a first gas driving device 72, a second gas driving device 73, an energy storage module, and a control module 75.

A cavity is formed in the casing 71, and the casing 71 is further provided with a first air inlet 71 1 and a air blowing port 712 which are respectively electrically connected to the cavity; the first air inlet 71 1 opens the cavity and the casing 71 The external conduction, that is, the first air inlet 71 1 conducts the cavity to the outside. The air supply port 712 is connected to the air duct.

The control module 75 is coupled to the first gas drive unit 72, the second gas drive unit 73, and the energy storage module, respectively, for controlling the operation of the first gas drive unit 72, the second gas drive unit 73, and the energy storage module.

The control module 75 can control the first gas driving device 72 to continuously operate to input external natural wind to the cavity through the first air inlet 71 1 , and output the temperature control air source to the air supply duct 712. The temperature-controlled wind source can be the outside natural wind or the external natural wind after heat exchange treatment.

In the temperature control unit provided by the embodiment, when the temperature difference between the external natural wind and the heat storage source provided by the energy storage module exceeds the preset temperature difference range, the natural wind between the control input and the heat storage source provided by the energy storage module exchange heat. The temperature of the natural wind can be fully utilized to exotherm and accumulate the heat storage source, so that the temperature control air source output to the external air supply pipe is kept within a small fluctuation range, thereby improving the temperature control at a lower cost. The cooling capacity of the unit.

Based on the above technical solution, optionally, the energy storage module may include: phase change material (Phase) Change Material, referred to as PCM) container 741 and heat pipe 742. The surface of the PCM container 741 is a heat insulating layer 7411, and a PCM 7412 is provided in the PCM 741 container. The heat pipe 742 partially protrudes into the PCM container 741 and is in contact with the PCM 7412; and the heat pipe 742 exposes a portion of the PCM container 741 adjacent to the second gas driving device 73. Optionally, a portion of the heat pipe 742 exposing the PCM container 741 may be provided with a plurality of heat exchange fins 743 at intervals to improve the heat exchange efficiency of the portion of the heat pipe 742 exposing the PCM container 741.

PCMs, such as Hydrated PCM and Paraffin Wax PCM, have properties that change shape with temperature and provide latent heat. When a phase change occurs in the PCM, such as when the PCM changes from a solid to a liquid or from a liquid to a solid, a large amount of latent heat is absorbed or released.

The outside temperature has a temperature difference at different times of the day, and the temperature difference between morning and evening is still relatively large in some seasons. When the outside air temperature is low, the PCM can perform the heat absorption function to perform the cold storage backup; in this case, the control module can drive the second gas driving device 73 to exchange heat with the external natural air passing through the heat pipe 742 and the PCM 7412 of the input cavity. The PCM7412 undergoes a first phase change for endotherm. When the outside air temperature is high, the PCM can exert the heat release characteristic to release the cold storage backup; in this case, the control module can drive the second gas driving device 73 to heat the external natural wind of the input cavity through the heat pipe 742 and the PCM 7412. In exchange, the PCM7412 undergoes a second phase change to cool the outside natural wind of the input cavity, and the first natural gas driving device 72 sends the natural wind input to the cavity and after the cooling process to the air supply duct. It can be seen that the present embodiment utilizes the natural temperature difference and the above characteristics of the PCM to further realize the technical effects of energy saving, cost saving and cost saving.

Further, external resources can be used to assist the PCM in the PCM container for energy storage recovery. An optional implementation, for example, the housing 71 of the energy storage module can also have a second air inlet 713, and the position of the second air inlet is opposite to the portion of the heat pipe 742 exposing the PCM container 741. External resources, such as cold air from external forced cooling, can be blown through the second air inlet 713, which exchanges heat with the PCM7412 in the PCM container 741 through the heat pipe 742 to cause the PCM 7412 to perform energy recovery.

In summary, the heat dissipation system provided by the embodiment of the invention has the advantages of compact structure, convenient maintenance, high heat dissipation efficiency, and favorable energy saving and consumption reduction. Specifically, the heat dissipation system provided by the embodiment of the invention combines the natural heat dissipation mode of the heat dissipation fins with the external forced cooling mode of the temperature control unit, and directs the temperature control air source of the external forced refrigeration to the surface of the equipment cabin and the fins for natural heat dissipation. Root, which raises the wireless The overall heat dissipation efficiency and reliability of the communication module; the air supply duct used in the external forced cooling mode can be deployed with the same communication pipeline of the power supply line and the data line of the wireless communication module, thereby improving the convenience of wiring the relevant cables of the wireless communication module. In the temperature control unit used in the external forced cooling mode, the natural temperature difference and the PCM have the characteristics of changing the shape with temperature and providing latent heat, thereby achieving the technical effects of energy saving, cost saving and cost saving.

Further, the heat dissipation system, the wireless communication module and the temperature control unit provided by the embodiments of the present invention can be remotely installed through the air supply duct, thereby reducing the convenience of installation operation and maintenance.
