SNAPPED FIN HEAT SINKS

Zipper & Stacked Fin Configurations

PrevNext

Manufacturing Process

 

Snapped fin (also know as stacked fin or zipper fin) heat sinks are manufactured by stamping sheets of rolled aluminum or copper into a tightly formed array of fins. A progressive tool is used in the stamping process to cut features and then interlock the fins together. Snapped fin heat sinks are most commonly integrated with heat pipes at the condenser end where they are used to cool the heat pipes, thus enabling the phase change.
