Problems solved by technology

[0007] The purpose of the present invention is to solve the problem that in the prior art, the heat dissipation of high-voltage frequency converters is mostly operated through air cooling, but the temperature of the cooling air flow blown out in a relatively hot environment is high, and it is difficult to quickly dissipate the heat emitted by the frequency converter. Take it away, it will greatly affect the heat dissipation performance of the high-voltage inverter, and it is not convenient for practical use. A high-voltage inverter integrated water-air cooling device is proposed.
