Description

Technical Field

[0001] The utility model relates to the field of cooling structures, in particular to a cooling structure for a screw air compressor. Background Art

[0002] Screw air compressor adopts pre-packaged configuration. Screw air compressor only needs a single power connection and compressed air connection, and has a built-in cooling system, which greatly simplifies the installation work. Screw air compressor provides high-quality compressed air for all walks of life with its advantages of high performance, high efficiency, maintenance-free and high reliability.

[0003] At present, screw air compressors are generally cooled by air cooling, but they are still subject to great restrictions in some special industries. When working under harsh environmental conditions, such as places with a lot of dust and powder, the air contains a lot of particulate impurities. When using air cooling, it is necessary to exchange the internal and external air. Due to the poor working environment, the particulate impurities in the air are easily attached to the heat pipe after being sucked into the chassis, reducing the heat dissipation effect of the heat pipe.
