Wakefield-Vette SKV Series skived fin heat sinks

The SKV Series skived fin heat sinks, from Wakefield-Vette, are designed to support the latest trends in renewable energy, industrial electrification and transportation.

The copper and aluminium skived fin heat sinks offer an alternative to extruded heat sinks for applications that require a thin fin density that cannot be achieved with extrusion technology. Skived heat sinks typically have 0.5 mm-thick fins.

Skived heat sinks are produced using a series of sharp knives that pass over the copper or aluminium material, producing a thin curl of metal which is then bent vertically to form the fin. Skived fins are produced from a bar of material that is approximately 5 m in length and then cut to size as required by the final application. The final heat sink can be machined using normal fabrication techniques.

Features of the series include: plastic push pins for easy insertion and integrity of the PCB; no interface between fins and base; minimal tooling cost for non-standards; and good thermal performance. Off-the-shelf as well as custom solutions are available.
