Description

Technical Field

[0001] The invention relates to the field of compressors, in particular to a cooler for a compressor. Background Art

[0002] The compressor is a driven fluid machine that boosts low-pressure gas to high-pressure gas. It is the heart of the refrigeration system. It sucks low-temperature and low-pressure refrigerant gas from the intake pipe, compresses it by driving the piston through the motor, and then discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe, providing power for the refrigeration cycle.

[0003] The compressor usually works with a tubular heat exchanger, which consists of a tube bundle, a shell, a tube sheet, an end cover, etc. When working, the hot and cold fluids flow in the tube and the shell (or vice versa), respectively, and heat is exchanged through the tube wall.

[0004] For example, a cooler for a compressor disclosed in the authorization announcement number CN217582440U includes a cooler body and a filter mechanism, the left and right sides of the cooler body are fixedly connected with end covers, the right end cover is fixedly installed with two grooves on the surface close to the cooler body, and two slots are provided in the two grooves, and the filter mechanism is provided in the recess of the right end cover, and the filter mechanism includes a ring movably connected to the recess of the end cover, a filter is fixedly installed on the surface of the recess of the ring, and two placement grooves are provided on the left side surface of the ring. After adopting the above technical solution, the beneficial effect of the utility model is as follows: by separating the right end cover from the cooler body and pulling the two pull blocks to the opposite side to pull the plug blocks out of the slots, the ring can be removed and the filter can be maintained and replaced.

[0005] Although the above patent can maintain and replace the filter, the cooler needs to be shut down during maintenance, which will cause the compressor to be unable to continue to be used. In addition, the filter assembly is arranged inside the cooler. During maintenance, the right end cover needs to be separated from the cooler body before the internal filter component can be taken out and cleaned. This maintenance method is inefficient and cumbersome. Summary of the invention
