Air cooling system for scroll compressors

摘要

An apparatus provides air cooling for a scroll compressor having a fixed scroll and an orbiting scroll. A plurality of fins are fixedly attached on a back surface portion of the fixed scroll. A cover assembly is disposed on the fins of the fixed scroll. The cover assembly and the fins of the fixed scroll form air passageways between the plurality of fins. A plurality of arcuately shaped fins are fixedly attached on a back surface portion of the orbiting scroll. A cover assembly is disposed on the fins of the orbiting scroll. The cover assembly and the fins of the orbiting scroll form air passageways between the plurality of fins. A shroud assembly surrounds the fixed and orbiting scrolls. The shroud assembly defines an interior portion around the fixed and orbiting scrolls, an intake aperture and a plurality of exhaust apertures. The shroud assembly has an exterior surface portion having a plurality of involutes formed thereon. The involutes define a plurality of air passageways which communicate with the interior portion of the shroud assembly. A fan draws a continuous volume of cooling air through the intake aperture, and accelerates the continuous volume of cooling air through the passageways defined by the involutes.
