Bonded Fin Heat Sinks

The bondedfin heat sink uses a grooved base plate designed to attach flat fin in set finpitch or position. Grooves in the base are sized to accept set thickness of finand provide a high level of heat transfer from the base to the fins fordissipation to air. Good groove design and assembly adds very little addedtemperature rise to the overall heat sink performance. Some designs useextruded fins that are swaged or cold-formed in place by deforming the basematerial over the fins in their grooves.
