Abstract
A radial finned heat sink assembly for an electrical component is constructed from a graphite material, which may be resin impregnated. The assembly includes a base, and a plurality of spaced parallel planar fin members supported by the base. Each fin member includes a planar fin of an anisotropic graphite material having graphite layers aligned primarily with the plane of the fin. In a first construction the fin members include integral core portions. In a second construction the core portions are separately formed so that the graphene layers of the core portion are aligned primarily parallel to the core axis so that heat is efficiently transmitted from the base to the plate members along the core axis.
