Skiving Fin Heat Sink

Skiving Fin Heat Sink can be constructed of aluminium or copper allowing for full, one-single-piece solutions without thermal barriers for high performance cooling.

Skiving Fin Heat Sink can offer highly optimized cooling as they allow for higher fin densities than what is manufacturable using extrusion methodologies, but do not have an interface joint that restricts heat flow like bonded or brazed fin heat sinks. These heat sinks are manufactured by precisely slicing the top of the base, called skiving, folding it back to where it is perpendicular to the base, and repeating at regular intervals to create fins.

The skiving process enables high fin density and thin fin heat sink geometries for optimal thermal performance. By packing as much fin surface area into a given volume, skived fin heat sinks have greater heat transfer than other single piece construction heat sinks such as extruded aluminum heat sinks.  Compared to extruded aluminum, skived fin heat sink fabrication does not rely on expensive tooling, providing greater design flexibility and faster prototyping. Instead, each fin is cut separately using the same tool which allows for lower tooling costs.

Our fin skiving machines can skive fins from 50µm till 3 mm thickness and handle prototype making without tooling and moulding costs, serial production or unmanned continue production.
