- Product Introduction
Product Description
Zipper fin heat sink is a type of heat sink that features thin and closely spaced fins that resemble the teeth of a zipper. This kind of heat sink is designed to dissipate heat effectively from electronic components and devices.
Our high-density zipper fin heat sinks redefine thermal management for commercial-grade LED systems. Utilizing precision skiving technology, we create ultra-thin fins (0.3-0.8mm) with unmatched packing density – delivering 40% more surface area than extruded solutions in identical footprints. Engineered specifically for extreme thermal management in compact LED arrays, these monolithic aluminum structures provide direct-attach cooling for COBs, multi-chip modules, and high-flux SMD arrays where space constraints prohibit conventional cooling.
