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 apertures extending through the walls of the individual fins. The formation of the apertures within the individual plate fins provides communication of fluid across the channels within the fin field.

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 textured regions positioned about a side surface of the fins and extending into an adjacent channel. The positioning of the textured regions function to minimize formation of high pressure within the fin field by disturbing the fluid flow passing along the fins. Alternatively or in conjunction with the above-outlined embodiments, the heat exchanger may comprise a fluid control feature for substantially preventing premature egress of fluid from a top region of the fin field caused by the high pressure region within the fin field.
