Description

Technical Field

[0001] The utility model relates to the technical field of compression refrigeration, in particular to a high-efficiency temperature reduction structure of a piston refrigeration compressor. Background Art

[0002] The piston refrigeration compressor is a mechanical device that compresses gas through the reciprocating motion of the piston in the cylinder. It is the core component of many refrigeration systems. With its mature technology and stable performance, it occupies an important position in the refrigeration industry, especially in small refrigeration equipment. Its principle is that the low-temperature and low-pressure refrigerant gas enters from the air intake port, is compressed by the piston driven by the motor, and becomes a high-temperature and high-pressure gas, which is then discharged to the exhaust port. This process provides the necessary power for the refrigeration cycle to achieve the steps of compression, condensation, expansion and evaporation.

[0003] The mature technology and stable performance of piston refrigeration compressors occupy an important position in the refrigeration industry. Since the refrigeration process requires compression, condensation, expansion and evaporation, it needs to continuously dissipate heat during operation. The internal part of the piston refrigeration compressor is not equipped with heat dissipation components. During use, it needs to be used with additional heat dissipation devices to improve its heat dissipation efficiency. Therefore, an efficient cooling structure of a piston refrigeration compressor is proposed. By setting a reasonable heat dissipation structure inside the compressor, the heat dissipation efficiency of the compressor is improved, thereby improving the operating efficiency of the compressor.
