[0002] In the refrigeration industry, there are two types of chillers: air-cooled chillers and water-cooled chillers. According to the compressor, they are divided into screw chillers, vortex chillers, and centrifugal chillers. In terms of temperature control, they are divided into low-temperature industrial chillers and normal-temperature chillers. The temperature of normal-temperature chillers is generally controlled within the range of 0 degrees to 35 degrees. The temperature control of low-temperature chillers is generally around 0 degrees to -100 degrees. Chillers are also called: freezers, refrigeration units, ice water units, cooling equipment, etc. Because they are widely used in various industries, the requirements for chillers are also different. Its working principle is a multifunctional machine that removes liquid vapor through compression or heat absorption refrigeration cycle.

[0003] Existing screw chillers generate a lot of noise when working. The usual way to reduce noise is to put a silencer on the surface of the chiller. This has a poor noise reduction effect and is difficult to disassemble. At the same time, the screw chiller generates a lot of heat when working, which needs to be dissipated. Utility Model Content
