The frequency converter further comprises an environment temperature sensor led out of the frequency converter body, a temperature sensor arranged on the radiator and a fan controller connected with the fan. A control circuit, an inverter, a rectifier and a chopper are arranged in the frequency converter body. With a chip CPU as the control circuit, the environment temperature sensor, the radiator temperature sensor and the fan controller are respectively connected with the control circuit. An outgoing line power circuit breaker is connected with a connected load end of the inverter, and the front end of the rectifier is connected with an incoming line power circuit breaker. According to the frequency converter, the temperature around the radiator and the environment temperature outside the frequency converter are detected, and fan delivery is adjusted and starting and stopping are controlled according to temperature difference values of the temperature around the radiator and the environment temperature outside the frequency converter. On the premise that reliable operation of power devices is ensured, the heat dissipation effect of a heat dissipation system can be effectively improved, noise can be reduced, efficiency of the frequency converter can be improved, and the service life of the fan can be prolonged.
