COOLING SYSTEM WITH ANGLED BLOWER HOUSING AND CENTRIFUGAL, FRUSTO-CONICAL IMPELLER

摘要

An improved cooling system for a computer is disclosed. In one embodiment, the improved cooling system includes an angled blower housing and a frusto-conical, centrifugal impeller. The computer chassis has a chassis air inlet and a chassis air outlet. A blower housing is disposed in the computer chassis. The blower housing has a blower inlet face spaced within 0.512 inches (1.3 cm) from a wall of the computer chassis and facing the wall. A blower air inlet is disposed on the blower inlet face and a blower air outlet is in communication with the chassis air outlet. A centrifugal impeller is rotatably supported in the blower housing about an axis of rotation to move air from the blower air inlet to the blower air outlet. The centrifugal impeller defines a generally frusto-conical profile when rotated about the axis of rotation.
