Aluminum Zipper Fin Soldering Heat Sink

Zipper fin heat sink is a perfect air cooling option for high power applications, a completed zipper fin stack is zipped together by a lot of metal sheets which are stamped. The fins shape, length, and height can be achieved by a custom tooling, the fins can be closed or open which are based on the customer airflow requirements.

The main materials of zipper fin are aluminum and copper, due to the cost consideration and aluminum even has a better heat dissipation ability, Aluminum zipper fin heat sink is more widely used for thermal option. Aluminum zipper fins are more cost effective and lightweight which compared with others high density fins solutions.

A finished aluminum zipper fin heat sink is usually soldered by aluminum zipper fins, aluminum or copper base and heat pipes to optimize the thermal performance. For high power applications, this heat sink assembly takes all the advantages for each components: Copper is a better thermal conductor, so it's used to manufacture a pedestal to contact the heat source to absorb the heat, then use the heat pipe to transfer the heat to the fins as heat pipe is a extraordinary heat transferring component, finally when the heat was transferred to the fins, due to the aluminum has a better heat dissipation ability, the heat can be dissipated to the ambient faster. Zipper fin heat sink has the flexibility of designing, so it allows the engineers to offer many thermal options based on customer's thermal requirements.
