The function and function of the compressor back cover
Jan 08,2026
Sealing and Protection:
The back cover is tightly fitted with the compressor cylinder or shell, forming a sealed space to prevent gas leakage and external impurities from entering.
Protect the internal components of the compressor from external environmental influences such as dust, moisture, etc.
Heat dissipation and cooling:
In some compressors, the back cover is designed with a heat dissipation structure, such as heat dissipation fins, cooling channels, etc., to help the compressor dissipate heat and maintain normal operating temperature.
Such as the thermal rods and heat dissipation fins in the back cover of car air conditioning compressors, as well as the cooling fans and exhaust fans in the protective plate structure of refrigerator compressor back covers.
Installation and fixation:
The back cover may serve as the installation foundation for other components of the compressor, such as fixing compressor coils, control circuit boards, etc.
Secure the compressor to the equipment using bolts or other connection methods to ensure its stable operation.
