Problems solved by technology

[0002] With the development of social economy and the increase of power supply load, the number of substations continues to increase. In order to save land, urban substations are mostly arranged indoors. However, due to the large heat generated during the operation of the main transformer, especially in summer, the ambient temperature is high and the load is large. , it is very easy to cause the temperature of the main transformer to be too high. If improper measures are taken, the heat cannot be discharged in time, which may cause the load reduction of the main transformer or even be forced to shut down, seriously affecting the safe operation of power.
[0003] Indoor substations mostly adopt the combination of mechanical ventilation and natural ventilation. Since the substation is in a closed space, the effect of natural ventilation is not good. The mechanical ventilation mostly uses indoor air conditioners and fresh air for cooling, and its energy consumption is relatively serious. Therefore, In the prior art, the heat pipe heat exchange system is mostly used for heat exchange
[0004] At present, the evaporator and condenser commonly used in the heat pipe heat exchange system are bare pipes, and the contact area between them and the heat transfer medium is relatively low, which affects the heat exchange efficiency of the heat pipe heat exchanger.
