Zipper Fin Heat Sink

Custom zipper fin heat sink

1.Product Introduction

Zipper Fin heat sinks can be an alternative to both extrusion and skived when looking for high density structure. Unlike skived fin, a zipper fin heat sink is an assembly of a base and a fin stack that are soldered or bonded together. The fin stack is created using a set of individually stamped fins which are joined together in several locations along the top and bottom edges. The location and number of joining features are determined by the design. Since the fins are stamped individually, they may have any shape and include other stamped features. While zipper fins are most often used with a base plate, they can also be used with heat pipes. A hole(s) is/are stamped into the fins and the fin stack set is placed on a series of heat pipes to form the heat sink. This type of construction is generally found in CPU coolers. Zipper fins can be manufactured from either copper or aluminum and it is possible to mix the different materials within a fin stack. The base can be either aluminum or copper as well. Depending upon the materials used, the finish is either a nickel plate or a chromate, either of which will improve the thermal performance and provide environmental protection.

2.Product Details

Zipper Fin heat sinks are an ideal air cooled solution for high powered forced convection applications for mass production. A zipper fin stack is constructed from a series of individual sheet metal fins that are stamped, folded, and zipped together using interlocking features.
