AI Technical Summary
Technical Problem
The double-layer muffler of the existing compressor has poor noise elimination effect in the medium and low frequency bands, and the muffler has poor noise elimination effect.
Method used
A resonance cavity is set in the muffler, which is composed of multiple unit cavities with different heights and/or widths. Multiple resonance cavities are formed between the inner and outer silencers, and grooves are set in the inner layer of the muffler to expand the volume of the resonance cavity and increase the resistance to airflow.
Benefits of technology
By increasing the volume of the resonance cavity and increasing the resistance of the airflow, the aerodynamic noise of the high-pressure refrigerant is significantly reduced and the silencing effect of the muffler is improved.

Abstract
The application provides a silencer and a compressor comprising the same, relates to the technical field of compressors, and solves the technical problem of poor silencing effect of the silencer. The silencer comprises a silencing body arranged on a flange, the silencing body has a resonance cavity, the resonance cavity is communicated with an exhaust port of the flange; the resonance cavity is formed by at least two unit cavities in series, all the unit cavities comprise at least two unit cavities with different heights and / or widths; the compressor comprises the flange and the silencer arranged on the flange. The application forms a plurality of resonance cavities with different volumes by arranging the resonance cavity into a plurality of unit cavities with different heights and / or widths. When the airflow enters the resonance cavity, the resonance cavity will vibrate, so that the airflow consumes sound energy by overcoming frictional resistance. Since the resonance cavities with different widths and / or heights are arranged in series, the resistance of the airflow is further increased, the aerodynamic noise of the high-pressure refrigerant is reduced, and the silencing effect of the silencer is improved.
