ABSTRACT:
An extruded, tiered high fin density heat sink (10) uses extruded first base, second base and bridging elements (12, 16, 14) having an arrangement of closely spaced, parallel fins (20, 26, 32, 38) and recesses (22, 28, 34, 40) for receiving opposing fins in the elements. The fins (20, 38) in the first and second base elements (12, 16) are bonded to recesses (28, 34) in opposite common faces (24, 30) of bridging elements (14) while fins (26, 32) extending from both opposing faces (24, 30) of bridging element (14) are bonded in aligned recesses (22, 40) in the first and second base element (12, 16) forming an extruded, tiered, high fin density heat sink (10).
