Description

Technical Field

[0002] In fully enclosed refrigeration compressors, the silencer chamber is a key component for reducing airflow pulsation noise, and its structural design directly affects the equipment's operational stability and noise level. Traditional silencers often use an assembly method combining an end-plane arc-shaped opening and elastic clips. This structure uses elastic clips to secure the silencer chamber to the cylinder head.

[0003] However, this type of design suffers from complex assembly processes and the elastic retainer is prone to fatigue failure during long-term operation, leading to decreased sealing performance and abnormal noise. Furthermore, the planar contact interface is susceptible to assembly gaps due to machining errors, further weakening the noise reduction effect. Utility Model Content
