Folded fin heat sinks are manufactured by bending aluminum.copper sheets into a variety of fin-shapes which are often bonded to a separate base .This type of folded fin heat sinks allows the base and the folded fins to be manufactured from difference materials.

Description:

Folded fins are created by a progressive stamping method. The fins are then bonded to a base with thermally conductive epoxy, brazing, welding,.similar metallurgical bonds, to .a heat sink. An advantage of folded fin heat sinks is the ability to combine aluminum and copper to tailor the performance of the heat sink to the particular application.

Folded fin heat sinks are best performers if there is ducted air - flow is directed through a duct of some kind directly at the heat sink. Fin pitch can be optimized in the heat sink manufacturing process making it very high performing. Also, because the heat sink material is folded, there can be a increase in surface area over which heat can be dissipated. Fold fin heat sinks have high heat flux density. The drawbacks to this type of heat sink are the cost including manufacturing and ducting necessary in your system. In some cases, plastic can be used to .a folded fin heat sink.

The applications of folded fin heat sinks :

IGBT’s.transistors

Telecommunications

Motor drives
