Fins heat sink
WebPin fin heat sinks are made through a forging process that enables you to use highly conductive alloys of aluminum and copper. These materials always enhance the … WebFolded Fin heat sinks are a good solution when looking for a medium to high density fin structure that is short in height (<2”). Generally formed from either copper or aluminum, a long sheet of material is folded back and forth to produce the fins. Depending upon the fin spacing and height, the fin tips can be flat or rounded.
