Abstract:
1. A heat sink with distributed jet cooling, the heat sink comprising: a base for thermal connection to at least one heated object; an array of fins thermally coupled to the base, wherein the fins are arranged in a staggered configuration to provide a v-groove cooling configuration; at least one multi-orifice synthetic jet or multiple single orifice jets disposed on a side of the array of fins, wherein at least a subset of the orifices are positioned to eject an ambient fluid directly on the fins, and wherein the ambient fluid is ejected perpendicular to a plane of the fins; and a fan disposed on an inlet side of the array of fins, wherein the fan is configured to draw the ambient fluid through the fins, and wherein the ambient fluid drawn by the fan interacts with the ambient fluid ejected from the multi-orifice synthetic jets or multiple single orifice jets to further enhance the cooling at least ten percent (10%) relative to a jet-free condition.
