Composite fins for heatsinks

摘要

A heat sink that dissipates heat from an electronic device. The heat sink comprises a base and one or more fins. The base is copper and is thermally coupled to an integrated circuit that includes a high-powered processor. The fins each include a copper portion and an aluminum portion. The copper portion of the fin is thermally coupled to the base to conduct thermal energy away from the base. The remainder of the fin is formed from aluminum.
