Abstract:
A radial finned heat sink assembly for an electrical component, comprising:a base constructed from graphite material; a plurality of spaced parallel planar fin members supported by the base, each fin member including a planar fin of an anisotropic graphite material having graphene layers aligned primarily with the plane of the fin, so that each fin has a thermal conductivity in directions parallel to the plane of the fin substantially greater than a thermal conductivity perpendicular to the plane of the fin, wherein each fin member has an opening defined therethrough; and a plurality of stacked connector members, each one of the connector members being closely received through the opening of an associated one of the fin members, each of the connector members being formed from a graphite material including graphene layers aligned primarily in a direction perpendicular to the planes of the fins.
