Aluminum Zipper Fin Heat Sinks

Zipper fin (also known as snapped fin or Stacked fin) heat sinks are manufactured by stamping sheets of rolled aluminum or copper into a tightly formed array of fins. Zipper fin solutions offer better performance when compared to typical extrusion heatsinks, due to thinner fin profiles leading to higher surface area and lower pressure drop.

Copper Zipper Fin Heat Sinks for CPU Cooler

A custom Zipper stacked Fin heatsink is made from sheets of aluminum or copper, where the metal is stamped into a particular configuration based on the intended application. For maximum design flexibility, fins can be stamped into a broad range of geometries and thicknesses. A stamped Fin custom heatsink is a useful solution for medium to high volume production.
