Description

technical field

[0001] The invention relates to the technical field of air conditioning, in particular to a refrigerant heat dissipation device for an air conditioning system, an air conditioning system with the refrigerant heat dissipation device, and a refrigerant heat dissipation method for the air conditioning system. Background technique

[0002] As the functions of the air conditioner gradually increase, the power devices carried by the air conditioner, such as IGBT (Insulated Gate Bipolar Transistor, insulated gate bipolar transistor) power devices, also continue to increase, and the heat generated by the electric control box is increasing.

[0003] In related technologies, for the problem of high heat generation of the electric control box, the solutions include air cooling and refrigerant cooling. Among them, air cooling requires additional cooling fans and air ducts in the air conditioner, which takes up a lot of space. Refrigerant cooling Since the state of the r...
