Abstract:
A method of forming a net-shape molded heat sink, comprising:providing a core plate of carbon-carbon matrix material having an outer surface with a first portion and section portion; injection overmolding a thermally conductive main body, having a top surface and a bottom interface surface and being made of a thermoplastic polymer composition molded with thermally conductive filler material, about the core plate of carbon-carbon matrix material thereby covering a first portion of the outer surface of the core plate and leaving the second portion exposed; and simultaneously forming a plurality of thermally conductive fins with said main body during injection molding the thermally conductive main body about the core plate of carbon-carbon matrix material, said fins integrally connected to and emanating from said top surface and being made of said thermoplastic polymer composition loaded with thermally conductive filler material.
