Abstract:
1. A cooling assembly for removing heat from an electronic device, said assembly comprising: a pump for circulating a flow of cooling fluid, a heat exchanger for removing heat from the flow of cooling fluid, a heat sink for transferring heat from the electronic device to the flow of cooling fluid and including a base plate for engaging the electronic device and having a top surface and a plurality of fins in spaced and parallel relationship extending upwardly from said top surface of said base plate a pre-determined height to a top extremity, a nozzle defining an exit for directing the flow of cooling fluid into said plurality of fins, said exit of said nozzle being disposed below said top extremity of said plurality of fins for discharging the flow of cooling fluid adjacent said top surface of said base plate, and wherein each fin of said plurality of fins includes an angled wall extending from a point proximate to the exit upwardly to said extremity at an acute angle to the base plate and diverging from said nozzle, wherein said heat sink includes a cap defining at least one outlet disposed above said top extremity of said plurality of fins for exhausting the flow of cooling fluid, wherein said plurality of fins defines a notch for receiving said nozzle such that said exit is below said top extremity, wherein said notch bisects said plurality of fins.
