Patent ID: 7301770

Claim:
A cooling apparatus comprising: a thermally conductive base having a main surface; a plurality of thermally conductive pin fins wire-bonded to the main surface of the thermally conductive base, wherein each pin fin of the plurality of thermally conductive pin fins is bonded to the main surface of the thermally conductive base via a metallurgical diffusion bond of the pin fin to the main surface of the thermally conductive base, the plurality of thermally conductive pin fins being disposed to facilitate transfer of heat from the thermally conductive base; and wherein the plurality of thermally conductive pin fins comprise a plurality of discrete, looped pin fins, each discrete, looped pin fin comprising a first end and a second end, and being separately wire-bonded at its first end and its second end to the main surface of the thermally conductive base employing a first metallurgical diffusion bond at its first end and a second metallurgical diffusion bond at its second end.
