Folded Fin Heat Sinks

The Aavid portfolio of folded fins includes over 3,000 different configurations that are manufactured for high heat transfer. Folded fins provide more surface area and design flexibility than extruded heat sinks and other fabrications. These fins can be purchased separately, bonded or brazed as part of a custom heat sink, or utilized in a thermal system such as a heat exchanger.

For rapid thermal modeling and comparison of multiple heat sink constructions please try Aavid Genie our heat sink design tool.
