Compressor rotors and compressors

Abstract

The invention relates to a compressor rotor and a compressor. The compressor rotor comprises an inner rotor and an outer rotor, wherein first toothed parts are arranged on the outer ring of the inner rotor in the circumferential direction; second toothed parts are arranged on the inner ring of the outer rotor in the circumferential direction; the inner rotor is assembled in the outer rotor; the first toothed parts and the second toothed parts are axially aligned, so that refrigerant channels are formed between first concave parts that are positioned between the first toothed parts and second concave parts that are positioned between the second toothed parts; and noise reduction cavities are formed in the refrigerant channels. According to the compressor rotor, the first toothed parts are arranged on the outer ring of the inner rotor in the circumferential direction; the second toothed parts are arranged on the inner ring of the outer rotor in the circumferential direction; the first toothed parts and the second toothed parts are axially aligned, so that the first concave parts between the first toothed parts and the second concave parts between the second toothed parts are axially aligned to correspondingly form the refrigerant channels with the noise reduction cavities; due to the noise reduction cavities, the refrigerant pneumatic noise is lowered, so that the pulsation noise of the compressor refrigerant is weakened; and in addition, the compressor rotor is compact in structure and easy to implement.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a compressor rotor and a compressor. Background technique [0002] For DC inverter compressors, the rotor has an iron core and built-in permanent magnet structure, and the stator has an iron core and winding structure. When the compressor is running, there is a magnetic field between the stator and the rotor. The tangential electromagnetic force and the axial electromagnetic force on the compressor rotor are relatively large. The electromagnetic force will cause the compressor rotor and pump body to vibrate, thereby driving the compressor shell, Vibration of the dispenser, radiated noise. Moreover, when the refrigerant is discharged from the pump body, aerodynamic noise will be generated. Contents of the invention [0003] In order to overcome the above technical defects, the technical problem to be solved by the present invention is to provide a compressor rotor and...
