Description

Technical Field

[0001] This utility model relates to the field of compressor technology, specifically to a compressor intake silencer. Background Technology

[0002] In the past, most compressor suction silencers used a simple combination of upper and lower silencer chambers. The refrigerant gas was directly drawn into the cylinder from bottom to top. The suction method was singular and could not effectively utilize the structure of the gas flow channel for noise reduction, resulting in loud compressor noise.

[0003] A search revealed Chinese Patent Publication No. CN215333309U, published on December 28, 2021, which discloses a compressor intake silencer. The paper states that the device is "comprising a right housing, a left housing, an intake port, an intake pipe, a rectangular connecting pipe, a long connecting pipe, and a partition. The right housing has an upper groove, and the lower part of the right housing has a half-intake port." The device is internally divided into three spaces, and the stitching plates are fixed by snap-fitting. The snap-fitted partition plates leave a certain gap, affecting the noise reduction effect of the device. In view of this, in-depth research was conducted to address the above problems, leading to this case. Utility Model Content

Multiple third sealing gaskets are installed on both sides of each locking block. The third sealing gaskets are installed on the outer walls of the first partition plate and the second partition plate. A fourth sealing gasket is provided on the outer side of each third sealing gasket. The fourth sealing gaskets are installed on the outer walls of another first partition plate and another second partition plate.

The third sealing gasket 707 and the fourth sealing gasket 709 are correspondingly fitted.

[0038] Working principle:

[0039] First, the two housings 1 are locked together and fixed. The interior of housing 1 is divided into three parts: lower silencer 9, upper silencer 10, and resonance chamber 11 by the tube 8. In use, gas flows from the intake port 5 along the inner wall of the inclined intake pipe 6 to the resonance chamber 11 and upper silencer 10. The gas expands and silences in the space of the resonance chamber 11. Then it flows through the tube 8 to the lower silencer 9. The gas continues to expand in the lower silencer 9 to reduce the pulse of the airflow. Finally, it enters the cylinder head of the compressor through the outlet of the long connecting pipe 3 at the top. The upper silencer 10 of this silencer can play a buffering role when the gas pressure in the resonance chamber 11 is high, further reducing the noise caused by the gas. When the gas pressure in the resonance chamber 11 is low, the gas can also be returned from the upper silencer 10 to the lower resonance chamber 11 to supplement the flow.
