Description

Technical Field

[0001] The utility model relates to the technical field of sound - damping copper tubes for rotary compressors, and more specifically, to an intake and exhaust copper tube with a sound - damping structure and a spring - loaded rotary compressor. Background Technique

[0002] The intake and exhaust copper tubes of a spring - loaded rotary compressor are important components in the compressor system. They are responsible for the intake and exhaust of gas respectively, and have a direct impact on the performance and efficiency of the compressor. Among them, the main function of the intake pipe is to suck in low - pressure and low - temperature gas into the compressor for compression and heating, so as to increase the temperature and pressure of the gas to meet the normal operation requirements of the machine. The main function of the exhaust pipe is to discharge the gas after operation.

[0003] However, when the spring - loaded rotary compressor is working, since the intake and exhaust copper tubes are at the intake and exhaust ends, high - pressure and high - temperature gas is quickly sucked in and discharged through the intake pipe and the exhaust pipe. To a certain extent, the gas flow will generate noise. This noise is usually related to the gas flow rate, pressure difference, and the design of the exhaust pipe.

[0004] In the prior art, for the technical problems of large noise and poor sound - damping effect of the intake and exhaust copper tubes, there is no particularly effective solution yet. Content of the Utility Model
