Abstract:
A heat exchanger for dissipating heat from a heat generating component, said heat exchanger comprising:a thermally conductive base in thermal communication with said component;a plurality of thermally conductive parallel plate fins affixed to said base and separated by channels;said fins defining a fin field having a top, a bottom, sides, an inlet region, and an exhaust region, wherein fluid flow through said fin field is parallel to the base;each fin has a height extending from said base to said top;a first set of alternating fins extend from the inlet region to the exhaust region;a second set of alternating fins extend from a central region, located between the inlet region and the exhaust region, to the exhaust region;wherein said plate fins comprising an open region between alternating fins for reducing friction on fluid passing through said channels.
