Abstract

The invention provides a heat dissipation device of a frequency converter, a control method of the heat dissipation device, a control device and an electric appliance. The heat dissipation device comprises at least one of a refrigerant contact type heat dissipation piece, a water cooling type heat dissipation piece and a fin cold air type heat dissipation piece. The refrigerant contact type heat dissipation piece is used for carrying out heat dissipation on a power contact type device in the frequency converter cabinet; and the water-cooled heat dissipation piece and / or the fin cold air type heat dissipation piece are / is used for dissipating the environment temperature in the frequency converter cabinet. According to the scheme provided by the invention, good heat dissipation conditions in the cabinet can be ensured, and normal operation of the frequency converter is protected.

Description

technical field [0001] The invention relates to the field of control, in particular to a heat dissipation device of a frequency converter and a control method thereof, a control device and an electrical appliance. Background technique [0002] At present, in response to the ambient temperature problem in the air-conditioning inverter cabinet, a branch of the external refrigeration system is mainly connected to the evaporator in the cabinet, and the refrigerant is used to exchange heat with the circulating air in the cabinet to reduce the ambient temperature in the cabinet. As the inverter is getting smaller and smaller, for the compact inverter, the existing evaporator size cannot be used in the cabinet. If the evaporator is not used for heat exchange, it will not be able to meet the ambient temperature inside the inverter cabinet. It will cause the air temperature in the cabinet to rise and cause faults, which will eventually affect the normal operation of the inverter. S...
