Rearward exhaust triple cooling air compressor structure

Abstract

A rear-exit triple-cooling air compressor structure includes a motor, an air guide shroud, a cylinder assembly, and an air delivery duct. The motor has an air guide shroud attached to its rear end and extends to connect to fan blades. An outer casing is attached to the motor, forming a heat dissipation channel between the casing and the motor. Multiple heat sinks are provided on the exterior of the casing. The cylinder assembly is attached to the front end of the motor and communicates with the air delivery duct. When the motor drives the fan blades, external cold air enters the motor through the air inlet of the air guide shroud, forming the first cooling mechanism. External cold air enters the heat dissipation channel through the gaps between the multiple blades of the air guide shroud, forming the second cooling mechanism. The multiple heat sinks on the exterior of the casing form the third cooling mechanism. Furthermore, the air delivery duct extends to the rear end of the motor, making the air compressor a rear-exit structure, thus saving space.
