Abstract:
1. A heat sink system to conduct heat away from a printed circuit board assembly, the heat sink system comprising: a chassis; a chassis cover to overlay a portion of the chassis, wherein the printed circuit board assembly is enclosed in the chassis; at least one thermally conductive block underlaying a high-heat section of the printed circuit board assembly, the at least one thermally conductive block in thermal contact with a respective at least one portion of the chassis; a plurality of thermally conductive through-rods each having a first end and a second end, wherein the plurality of first ends thermally contact one of the at least one thermally conductive block and wherein the plurality of second ends thermally contact the chassis cover, wherein the plurality of through-rods are positioned in a respective plurality of holes formed in the printed circuit board; and at least one thermally conductive notch-rod associated with a respective thermally conductive block, the at least one thermally conductive notch-rod having a first end and a second end, wherein the at least one first end of the at least one thermally conductive notch-rod thermally contacts the associated thermally conductive block and wherein the at least one second end thermally contacts the chassis cover, wherein the at least one notch-rod is positioned in a notch formed in the printed circuit board assembly.
