[0002] With the progress of society and the development of technology, people have higher and higher requirements for the structure of home appliances on the basis of the rapid improvement of material living standards. Air conditioners are increasingly regarded as indispensable household appliances in people's lives. Inverter air conditioners have been widely promoted in the market due to their advantages such as energy saving and low noise.

[0003] The displacement and frequency of variable frequency air conditioner compressors are also constantly increasing, commonly 85-90HZ, and some exceed 110HZ. The heat generated by its drive module is also greatly increased, which can easily lead to excessive temperature of electrical components inside the air conditioner and heat accumulation. Especially in the summer, when the temperature is high and the operating time of the air conditioner is prolonged, the electrical components are continuously in a heating state. Coupled with the high temperature environment outside, the air conditioner cannot get sufficient heat dissipation, resulting in damage to the air conditioning equipment.

[0004] In view of this, the inventor conducted in-depth research on this demand, and thus the present case was produced. Utility Model Content

[0007] The refrigerant sleeve is provided with a refrigerant pipeline for supplying refrigerant, and the cooling section is arranged in the refrigerant pipeline;

[0008] A heat spreader, the evaporation section is fixedly mounted on the heat spreader.

[0009] Furthermore, the heat spreader is mounted on the electrical components that require heat dissipation by means of silicone adhesive.

[0010] Furthermore, the evaporation section is flat, the evaporation section is welded on the heat spreader, and the evaporation section and the electrical component are correspondingly arranged through the heat spreader.

[0011] Furthermore, one end of the cooling section is inserted into one end of the refrigerant sleeve, and an outer wall surface of the cooling section forms a gap with the refrigerant pipeline.

[0012] Furthermore, the outer surface of the cooling section is provided with threads.

[0013] Furthermore, a liquid inlet pipe and a liquid outlet pipe are respectively provided at the other end of the refrigerant sleeve, and the liquid inlet pipe and the liquid outlet pipe are connected to form the refrigerant pipeline. The refrigerant enters from the liquid inlet of the liquid inlet pipe, flows through the refrigerant pipeline, and flows out from the liquid outlet of the liquid outlet pipe.

[0014] Furthermore, the cooling section is welded to the refrigerant sleeve.

[0015] Furthermore, two heat pipes are provided, and the evaporation sections of the two heat pipes are sintered and fixed on the heat spreader, and the two cooling sections can be adaptively arranged in the liquid inlet pipe and the liquid outlet pipe, respectively.

[0016] Furthermore, a plurality of the heat pipes are provided, and the plurality of heat pipes are integrally arranged, and the cooling section of the heat pipe can be adaptively inserted into the liquid inlet pipe, or the cooling section can be adaptively inserted into the liquid outlet pipe.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] 1) The two ends of the heat pipe are connected to the vapor chamber and the refrigerant sleeve respectively. The heat pipe is used to transfer the heat of the small area with high heat flux density in the heating area of ​​the vapor chamber to the refrigerant sleeve. The refrigerant in the refrigerant sleeve flows, and the cooling section of the heat pipe can be fully cooled, taking away the heat brought by the evaporation section of the heat pipe to achieve effective heat dissipation.

[0019] 2) Use the refrigerant of the air conditioner for heat dissipation, and utilize a small amount of cooling capacity of the air conditioner, avoiding the need for an additional refrigeration cycle system for heat dissipation, saving costs, and improving the heat dissipation efficiency of the inverter, ensuring the operating reliability and cooling efficiency of the inverter air conditioner.
