Abstract:
1. A cooling apparatus comprising: a manifold structure comprising a jet orifice plate for injecting coolant onto a flat surface to be cooled when the cooling apparatus is employed to cool at least one electronic component, wherein the flat surface to be cooled comprises a surface of the at least one electronic component; wherein the jet orifice plate comprises a plurality of jet orifices for directing coolant at the surface to be cooled, the jet orifice plate being configured with a plurality of jet orifice structures, each jet orifice structure projecting from a first surface of the jet orifice plate towards the surface to be cooled when the cooling apparatus is employed to cool the at least one electronic component, each jet orifice structure including a respective jet orifice of the plurality of jet orifices, and wherein the plurality of jet orifice structures are sized and spaced to define coolant effluent removal regions therebetween which facilitate removal of coolant effluent from over a center region of the at least one electronic component to a peripheral region thereof when the cooling apparatus is employed to cool the at least one electronic component, thereby reducing coolant pressure drop across the jet orifice plate; wherein the jet orifice plate comprises a stamped, unitary base plate of uniform thickness with the plurality of jet orifice structures projecting across the first surface of the jet orifice plate, and wherein the jet orifice structures have a common geometrical configuration; and wherein the common geometrical configuration is a conical configuration, and wherein a second surface of the jet orifice plate comprises a plurality of funnels formed by the plurality of jet orifice structures of conical configuration projecting from the first surface of the jet orifice plate, each funnel directing coolant towards a respective jet orifice of the plurality of jet orifice structures for jet impingement on the surface to be cooled.
