Abstract
A thermo-electro sub-assembly comprises a gas supply, a first duct, a first heatsink adjacent a first device, a second duct, and a second heat sink adjacent a second device. The gas supply may be realized as a fan, a blower, or a compressed gas source. The first duct provides a passageway for delivering pressurized gas from the gas supply to the first heat sink. The duct may include a plurality of vanes for reducing the turbulence and air boundary separation within the duct. The first heatsink is in thermal communication with a first heat-producing device such as a microprocessor. In a preferred embodiment the heatsink comprises an axial shaped folded fin heatsink. The second duct is used to provide a pathway for the air leaving the first heatsink and delivers the air to the second heatsink. The second duct may also include a plurality of vanes for reducing turbulence and boundary flow separation within the second duct.
