Zipper Fin Heat Sink

Description

Zipper fin heat sinks have a high level of design flexibility which enables to design integrated solutions with heat pipes, ducting, and fans or blowers to meet specific customer application requirements. A zipper fin stack is constructed from a series of individual sheet metal fins that are stamped, folded, and zipped together using interlocking features. A completed zipper fin stack is typically soldered, brazed, or epoxied to a heat sink base or a series of heat pipes to create a comprehensive thermal management assembly. As zipper fins are joined together on both the top and bottom of the fins, they offer higher mechanical stability. These types of heat sinks are the right choice because they are designed with high aspect ratio fin heat sink profiles, enabling taller, thinner and more densely fin heat sink for increased surface area and improved cooling performance so zipper fin heat sink is also called high performance heat sink.
