Zipper-fin heat sinks can protect components from excess heat in applications where other high-fin-density heat-sink types are used. The heat sinks are machined from thin sheet metal (typically aluminum or copper) and formed into custom shapes. The zipper-fin sinks can be designed with integral ducts to contain and optimize cooling airflow, which improves thermal performance, particularly with active sinks that receive airflows from fans and blowers. The top surface of the heat sink can also be used as a heat spreader for hot components.
