A temperature sensor 16 is provided at the lower end of the heat dissipation body 10, and the temperature sensor 16 extends to the center position of the inverter body 6. It should be additionally explained that the temperature sensor 16 cooperates with the electronic control system to automatically detect the real-time temperature of the inverter body 6, and the temperature sensor 16 can be used to detect the high temperature warning temperature interval value set by the system. When the high temperature warning interval is reached, the system drives the heat dissipation body 10 to perform heat dissipation operations. The technical contents are all existing publicly available technical solutions and will not be repeated here.

[0024] Furthermore, the first air duct 13 is a vertical through structure, and the second air duct 14 is an inclined arc through structure.

[0025] In one embodiment, when the temperature detected by the temperature sensor 16 reaches the warning temperature, the system starts the motor 11 of the heat dissipation body 10.
