The air duct guides the cool air output by the temperature control unit to the diversion box 62 through the air inlet 621, and the cool air in the diversion box 62 flows to the second gap 66 through each air outlet 622 and flows along the arrow shown in fig. 6, so as to take away the heat on the surface of the equipment compartment 61 and the root of the heat exchange fin 64.
The technical scheme that this embodiment provided combines the natural heat dissipation mode of using radiating fin and the outside refrigeration mode of forcing of control by temperature change unit, and the outside refrigeration mode of forcing of control by temperature change unit is with the cold wind water conservancy diversion of forcing refrigeration to equipment cabin surface and heat transfer fin's root, has increased the contact probability of cold wind and equipment cabin surface, has improved the utilization ratio of cold wind to this refrigeration mode of forcing can not weaken radiating fin's the radiating effect of the natural heat dissipation mode, has improved wireless communication module's radiating efficiency on the whole.

The cable inlets a-c can be respectively used for connecting a power line, a data line and a wind transmission pipeline; the power line, the data line and the air duct may be laid by using the same communication duct, and the laying manner is similar to that described in the corresponding embodiment of fig. 5, and is not described herein again.
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 drive 72, a second gas drive 73, an energy storage module, and a control module 75.
A cavity is formed inside the shell 71, and a first air inlet 711 and an air supply outlet 712 which are respectively communicated with the cavity are further formed in the shell 71; the first air inlet 711 communicates the cavity with the outside of the housing 71, that is, the first air inlet 711 communicates the cavity with the outside. The supply air outlet 712 is connected to a supply air duct.

On the basis of the above technical solution, optionally, the energy storage module may include: a Phase Change Material (PCM) container 741 and a heat pipe 742. The surface of the PCM container 741 is an insulating layer 7411, and the PCM741 container is provided with a PCM7412 therein. 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 pack 741 adjacent to the second gas driving device 73.

PCMs, such as Hydrated (Hydrated) PCM and waxy (Paraffin Wax) PCM, have the property of changing morphology with changes in temperature and providing latent heat. When the PCM undergoes a phase change, such as a change from solid to liquid or from liquid to solid, a large amount of latent heat is absorbed or released.
The outside temperature has temperature difference in different time periods of a day, and the temperature difference is still larger in the morning and evening in some seasons. When the outside temperature is low, the PCM can exert the heat absorption characteristic to carry out cold accumulation backup; in this case, the control module may drive the second gas driving device 73 to exchange heat with the PCM7412 through the heat pipe 742 for the external natural wind introduced into the cavity, so that the PCM7412 undergoes a first phase change to absorb heat. When the outside temperature is higher, the PCM can exert the heat release characteristic to release cold accumulation backup; in this case, the control module may drive the second gas driving device 73 to perform heat exchange between the external natural wind input into the cavity and the PCM7412 through the heat pipe 742, so that the PCM7412 undergoes the second phase change to perform refrigeration processing on the external natural wind input into the cavity, and the external natural wind input into the cavity and subjected to the refrigeration processing is sent into the wind delivery pipeline through the first gas driving device 72. Therefore, the present embodiment further achieves the technical effects of energy saving, consumption reduction and cost saving by using the natural temperature difference and the above characteristics of the PCM.
Furthermore, external resources can be used for assisting the PCM in the PCM container to perform energy storage recovery. An alternative implementation is for example: the housing 71 of the energy storage module may further have a second air inlet 713, where the second air inlet is located opposite to the portion of the heat pipe 742 exposed from the PCM container 741. External resources, such as cold air for forced cooling from the outside, can be blown in through the second air inlet 713, and the cold air exchanges heat with the PCM7412 in the PCM container 741 through the heat pipe 742, so that the stored energy of the PCM7412 is recovered.
In summary, the heat dissipation system provided by the embodiment of the invention has the advantages of compact structure, convenience in maintenance, high heat dissipation efficiency and contribution to energy conservation and consumption reduction. Specifically, the cooling system provided by the embodiment of the invention combines a natural cooling mode of the cooling fins with an external forced cooling mode of the temperature control unit, and guides the external forced cooling temperature control air source to the surface of the equipment cabin and the roots of the fins for natural cooling, so that the overall cooling efficiency and reliability of the wireless communication module are improved; the air delivery pipeline used in the external forced refrigeration mode can be arranged with the power line and the data line of the wireless communication module by using the same communication pipeline, so that the convenience of arrangement of related cables of the wireless communication module is improved; in the temperature control unit used in the external forced refrigeration mode, the natural temperature difference and the characteristic that PCM has the form changed along with the temperature change and can provide latent heat can be utilized, and the technical effects of saving energy, reducing consumption and saving cost are realized.
Furthermore, the heat dissipation system, the wireless communication module and the temperature control unit provided by the embodiment of the invention can be installed remotely through the air delivery pipeline, so that the convenience of installation operation and maintenance is reduced. The embodiment of the invention can also be applied to complex and severe environments such as remote iron towers (such as iron towers with the height less than 70 m), building rooftops, elevated platforms and the like; in the application, the wireless communication module and the temperature control unit can be remotely installed through the air delivery pipeline, if the temperature control unit is installed at a low position which is convenient for operation and maintenance, the maintenance convenience is improved, and the temperature control unit is installed at the low position and does not need to be installed at the high position, so that the safety of the heat dissipation system is also improved.
