The invention provides a heat dissipation control method and device of a frequency converter power module, a medium and a radiator. The method comprises the steps that a chilled water loop is arranged on the radiator of the frequency converter power module; and a chilled water inlet and a chilled water outlet of the chilled water loop are respectively connected with a chilled water valve, a water pump is arranged between the chilled water outlet and the chilled water valve, and chilled water circulation can be realized by controlling the chilled water valve and the water pump. According to the scheme provided by the invention, energy efficiency can be utilized to the maximum extent, and the service life of equipment devices is prolonged.
Description
technical field [0001] The invention relates to the field of control, in particular to a heat dissipation control method, device, medium and radiator of a frequency converter power module. Background technique [0002] With the improvement of people's living standards, the use of central air conditioners in projects is becoming more and more popular, and the concepts of energy saving, comfort and environmental protection of inverter air conditioners have become the consensus of everyone. With the development of technology, inverter products are the basis for ensuring their reliability. It is developing in the direction of modularization, small size, and high integration. Since liquid cooling of modules is more suitable for the development trend than air cooling, at this stage, inverters for air conditioners mostly use refrigerants to dissipate heat for inverters. At present, shopping malls, hotels, and railways Large changes in traffic and other types of engineering loads le...
