Compressor

Abstract

The invention discloses a compressor which comprises a motor. A stator (31) of the motor comprises a stator iron core (311) and a coil winding (312). Arch coils are formed by the part, exposed out of the end face of the stator iron core, of the coil winding. The maximum axial distance between the coils and the end face of the stator iron core is L, and the minimum axial width of the coils is W, wherein W is larger than or equal to 0.5 L. By means of the compressor, the shape and size of the motor coils of the compressor are optimally designed, the size of the gap formed between the coils which are circumferentially arranged on the end face of the stator iron core is reduced, the contact area between the coils and an oil-gas mixture is enlarged, a very good oil-gas separation effect is achieved, the phenomenon that refrigerating machine oil spit out from the compressor forms an oil film, and consequently the heat exchange performance of a heat exchanger is affected is avoided, and the reliability of the compressor is greatly improved through the coil structure.

Description

technical field [0001] The invention belongs to the field of compressors, and more specifically relates to a compressor. Background technique [0002] During the operation of the air-conditioning compressor, the oil such as refrigerating machine oil in the compressor easily forms an oil-air mixture with the gaseous refrigerant. The inner wall of the air conditioner forms an oil film, which affects the heat exchange efficiency of the heat exchanger, resulting in insufficient cooling or heating capacity of the air conditioner. [0003] Therefore, in order to prevent the performance of the air-conditioning system from being affected by the excessive oil output of the compressor, it is necessary to optimize the internal structure of the compressor to reduce the oil-air mixture entering the heat exchanger. Contents of the invention [0004] In view of the above-mentioned shortcomings or defects in the prior art, the present invention provides a compressor, which can effectivel...

AI Technical Summary

Problems solved by technology

[0002] During the operation of the air-conditioning compressor, the refrigerating machine oil and other oils in the compressor are easy to form an oil-air mixture with the gaseous refrigerant, and the oil-air mixture will flow into the heat exchanger along with the exhaust pipe of the compressor and be discharged in the heat exchanger. An oil film is formed on the inner wall of the heat exchanger, which affects the heat exchange efficiency of the heat exchanger, resulting in insufficient cooling or heating capacity of the air conditioner
