Our expertise in stacked heat sink manufacturing spans over a decade, serving diverse industries including telecommunications, automotive electronics, power electronics, and industrial equipment. We are not just suppliers – we are your manufacturing partner committed to excellence.
Stacked heat sinks, also known as zipper fin or snapped fin heat sinks, are constructed by stamping sheets of aluminum or copper into tightly formed arrays of fins that are pressed together under high pressure.
These heat sinks feature thinner fin profiles compared to traditional extrusion heat sinks, providing higher surface area and lower pressure drop for enhanced thermal performance.
Ideal for high-power devices requiring cooling from both sides, featuring dual cooling base plates with fins in the middle for optimal heat dissipation.
Individual fins are stamped from aluminum or copper sheets with precise dimensional control and surface finish.
Multiple fins are pressed together under high pressure to create the complete stacked heat sink structure.
CNC machining, drilling, tapping, and surface finishing to meet exact specifications.
