Abstract
A housing for a desk top personal computer incorporating a novel integrated cooling system. The housing features a cast magnesium chassis that acts as a heat sink that conductively absorbs heat from internal components. A recessed, rectangular, open-sided cooling channel is integrally formed in the bottom of the chassis. A fan is mounted to one end of the cooling channel. A series of fins running lengthwise extends down from the top of the channel. A power supply module, which dissipates heat from a conduction plate along its bottom, is mounted on the top side of the chassis directly above the channel. In operation, the fan draws air into the housing through a series of openings along the top back edge of the chassis. The air passes over the inside surfaces of the chassis, dissipating the relatively small amount of heat generated by the components mounted thereon and flows into the cooling channel. The air flows through the channel and across the surfaces of the fins extending down from the top of the channel, dissipating the heat generated by the power supply mounted directly above.
