Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange equipment, in particular to a heat exchange mechanism for an air compressor. Background Art

[0002] An air compressor is a device used to compress gas. The structure of an air compressor is similar to that of a water pump. Most air compressors are reciprocating piston type, rotary blade or rotary screw. Centrifugal compressors are very common and can be divided into three categories based on their working principles: volumetric, dynamic and thermal compressors.

[0003] When the existing heat exchange mechanism for air compressors is in use, when the hot air contacts the heat exchange tube, it will condense into condensed water on the outer surface of the heat exchange tube. The condensed water remaining on the surface of the heat exchange tube will increase the heat exchange thermal resistance between the air and the heat exchanger, making it difficult for the hot air to fully contact the heat exchange tube. The hot air cannot be fully cooled, resulting in reduced heat exchange efficiency.

[0004] Therefore, it is necessary to provide a heat exchange mechanism for an air compressor to solve the above technical problems. Utility Model Content
