[0002] The important role that electricity plays in our lives and production cannot be ignored. It brings us great convenience and becomes an important energy source in our production and life. The most critical factor that enables the normal operation and transmission of electricity in power plants is electrical equipment.

[0003] Since electrical equipment will continue to generate heat during operation, if the heat is not dissipated in time, it will cause damage to the electrical equipment, thereby reducing the service life of the electrical equipment. However, the heat dissipation structure of existing electrical equipment is relatively simple and is insufficient to dissipate the heat generated by the electrical equipment, resulting in reduced working efficiency of the electrical equipment during operation, thereby causing the electrical equipment to be damaged due to high temperature. There is currently no reliable technical solution. Utility Model Content

[0006] Preferably, a plurality of heat dissipation fins integrally connected thereto are fixedly mounted on the bottom end of the heat dissipation plate.

[0007] Preferably, the controller is a single chip microcomputer, the temperature sensor is a thermocouple, and the fan, circulation pump, condenser, temperature sensor and controller are electrically connected to an external power supply.

[0009] Preferably, the inner wall of the first heat exchange channel is coated with a first graphene coating.

[0010] Preferably, the inner wall of the second heat exchange channel is coated with a second graphene coating.

[0011] In summary, the technical effects and advantages of the utility model are:

[0012] In the utility model, the hot air inside the electrical equipment is sent into the first heat exchange channel for heat exchange through the fan, and the heat is transferred to the heat sink, and the heat is dissipated through the heat sink. When the temperature of the heat sink is too high, the temperature sensor detects the signal and transmits it to the controller. The controller controls the circulation pump to start and drives the coolant inside the second heat exchange channel to circulate. During the flow, the coolant is cooled by the condenser, thereby cooling the heat sink, achieving reliable heat dissipation of the electrical equipment and avoiding the problem of dust entering the interior due to the opening of a heat dissipation port in the electrical equipment.
