Abstract

A method of manufacturing a high performance, high fin density heat sink (10) uses extruded first and second base elements having an alternating arrangement of closely spaced fins and recesses for receiving opposing fins. The fins in the first and second base elements are bonded to the recesses formed in the common face of the opposing base element to form the bonded extruded heat sink.
