Title:
FINNED HEAT SINK ASSEMBLIES
Document Type and Number:
WIPO Patent Application WO2002089538
Kind Code:
A3
Abstract:
A finned heat sink is constructed from a plurality of components separately formed from graphite materials. Components include a base and a plurality of fins. In one embodiment, the base (302) is constructed from a first graphite material, and a plurality of elongated fins (304a, 304b, etc.) is constructed from a second graphite material, which may be the same material as the first graphite material. The fins each extend at least partially into the base, and have a length extending away from the base parallel to each other. The graphite material of the fins includes graphene layers aligned in planes parallel to the length of the fins. Two constructions are provided for the base. In one construction the base includes graphene layers aligned in planes parallel to the length of the fins. In another construction the base includes graphene layers aligned in planes perpendicular to the length of the fins.
