Abstract:
1. A heat sink assembly for removing heat from an electronic device, said assembly comprising: a base having a top surface, a lid having a bottom surface in spaced relationship with and parallel to said top surface of said base, a vertical nozzle elongated along an inlet axis and extending through said lid for emitting fluid against said top surface of said base, an outer wall extending vertically between said top surface of said base and said bottom surface of said lid, a plurality of spaced and parallel fins extending upwardly from said top surface of said base to said lid and extending transversely from and in opposite directions from said inlet axis to outer ends for directing the flow of cooling fluid laterally from said inlet axis and out of said outer ends, and characterized by a confining plate extending parallel to and along each lateral side of said fins and extending upwardly from said top surface of said base to said bottom surface of said lid to define an outlet chamber extending from said outer ends of said fins and outside of said fins back toward said vertical nozzle and an outlet disposed on said inlet axis outwardly of each of said confining plates for collecting fluid flow on each side of said fins.
