[0002] At present, frequency converters are widely used. During the normal operation of the frequency converter, the frequency converter often generates a certain amount of heat. If used for a long time, a large amount of heat will accumulate. If there is no reasonable cooling method, the temperature inside the frequency converter will rise rapidly. An overly high temperature working environment will lead to product failure and a reduction in the service life of the equipment.

However, after each processing is completed, one side of the surface of both sides of the housing will be adhered to the thermal oil. If it is not cleaned in time, a layer of oil and dirt will be adhered to the surface of the housing after long-term use, making subsequent cleaning cumbersome and affecting the subsequent thermal conductivity.
