Heat sink with arc shaped fins

Abstract

A heat exchanger and a method of manufacturing the heat exchanger is disclosed for dissipating heat from a heat generating component. The heat exchanger comprises a thermally conductive base in thermal communication with the component, a plurality of thermally conductive plate fins affixed to the base wherein the plate fins define a fin field and channels, and fluid control for controlling the fluid flow within the fin field. The individual fins of the heat exchanger comprise an arc shape with diametrically opposed legs extending vertically downward from each end of the fins. The individual fins are comprised of thermally conductive material affixed to and in thermal communication with the base. The individual fins are arcuately shaped sections separated by arcuately shaped channels. The fins, together with the channels and base form a fin field having an inlet region, a middle region and an outlet region. Additionally, the fins may comprise a plurality of orifices, slots and/or apertures to enhance cross channel fluid communication, and/or textured surface regions in the form of surface anomalies for disrupting formation of a boundary layer along said fins.
