Compressor

Abstract

The invention discloses a compressor which comprises a housing, a compression mechanism part and a motor part, wherein the compression mechanism part comprises an air cylinder with an exhaust port and an intake port; the motor part comprises a stator and a rotor which are fixedly arranged on the inner peripheral wall of the housing; the stator comprises a stator iron core and a coil winding; the part, positioned on the upper end surface of the stator, of the coil winding is a first coil; the part, positioned on the lower end surface of the stator, of the coil winding is a second coil; the inner peripheral wall of the second coil is connected with the lower end surface of the second coil through an inclined section; the inclined section extends downwards in an inclined mode in an outward direction; length of the inclined section is L2, the inner diameter of the housing is D, and the outer diameter of the first coil is D1, wherein L2, D and D1 at least meet one of the following relationships: D1 greater than or equal to 0.92 D, and L2 greater than or equal to 10 mm. According to the compressor disclosed by the invention, oil throughput capacity of the compressor is reduced, and the problem that heat exchange of a heat exchanger is affected due to the fact that frozen machine oil forms an oil film on the heat exchanger is avoided.

Description

technical field [0001] The invention relates to the refrigeration field, in particular to a compressor. Background technique [0002] The air-conditioning rotary compressor of the related art needs refrigeration machine oil inside the compressor to play the role of cooling, sealing and lubricating during the working process. During the cycle operation of the refrigeration system, the refrigeration oil usually flows out of the compressor along with the refrigerant and flows into the heat exchanger. Refrigerator oil will stay on the inner wall of the heat exchanger to form a thick oil film. Due to the small thermal conductivity of the oil film, the heat transfer performance of the heat exchanger will decrease, thereby affecting the cooling or heating capacity of the air conditioner. At the same time, the internal parts of the compressor will also increase wear due to the lack of lubrication of the refrigerating machine oil, which will affect the performance of the compressor ...

AI Technical Summary

Problems solved by technology

Refrigerator oil will stay on the inner wall of the heat exchanger to form a thick oil film. Due to the small thermal conductivity of the oil film, the heat transfer performance of the heat exchanger will decrease, thereby affecting the cooling or heating capacity of the air conditioner.

At the same time, the internal parts of the compressor will also increase wear due to the lack of lubrication of the refrigerating machine oil, which will affect the performance of the compressor and reduce the reliability of the compressor
