Zipper Fin Heat Sinks

Zipper fin heat sinks use a cassette of stamped aluminium or copper which can then be soldered or epoxy bonded to a custom machined base. The fins can be straight or folded to a ‘C’ shape to create a duct for the airflow.

The fins are zipped together using a locking feature which provides mechanical stability with low tooling costs. These fins can also be pressed onto heat pipes to create very efficient heat pipe/fin stack assemblies.
