[0002] At present, in the existing technology, in the frequency conversion heat pump air conditioner unit, the heat dissipation of the power module is solved by the fan. The defect of this method is that the module cannot dissipate heat when the unit needs to stop the fan; it is also cooled by the return air of the compressor. The defects of these solutions It is impossible to control the surface temperature of the module, which leads to the condensation on the surface of the module and the failure of the module

Abstract
A heat dissipation device of a power module comprises a recoverer, a fluorine pipeline, a first expansion valve, a second expansion valve, a fluorine pipeline expansion valve, a first one-way valve, a second one-way valve and a module heat exchanger. A frequency conversion air conditioner comprises a compressor, a four-way valve, the recoverer, a heat exchanger, an outdoor unit and the fluorine pipeline expansion valve arranged on the fluorine pipeline between the heat exchanger and the outdoor unit. The frequency conversion air conditioner is characterized by further comprising the first expansion valve, the second expansion valve, the fluorine pipeline expansion valve, the first one-way valve, the second one-way valve and the module heat exchanger. The heat dissipation device of the power module can keep the work environment, such as high temperature preventing and moisture condensation preventing, of the power module during air conditioner refrigerating or heating. According to the frequency conversion air conditioner, the power module is located at the environment suitable for working of the frequency conversion air conditioner in winter or summer; and normal work of the compressor is ensured, and control effectiveness is ensured.
Description
