Abstract:
1. An apparatus for cooling a heat-generating device comprising: a heat sink formed from diamond-silicon carbide, said diamond-silicon carbide having a diamond concentration of between 30 percent and 70 percent, said heat sink including a base having a plurality of heat transfer enhancing elements protruding from a surface thereof in accordance with a spatial distribution, said heat transfer enhancing elements integrally formed from said diamond-silicon carbide in single piece formation with said base, said heat sink having a diamond coating on a surface of said base opposite said surface having said heat transfer enhancing elements, the heat-generating device being mounted to said surface of said base opposite said surface having said heat transfer enhancing elements; a cap coupled liquid-tight to said base of said heat sink so as to enclose said heat transfer enhancing elements therein, said cap having a liquid inlet and a liquid outlet formed thereon; and a cooling liquid flowing through said cap and in heat transport relation with said heat transfer enhancing elements so as to dissipate heat generated by the heat-generating device.
