High-Fin Heat-Sink Profiles

The challenge in heat-sink profiles is feeding equal metal to thin, deep fins. With flow balancing and bearing design for high-fin-ratio geometries, KALEKS ensures fins fill completely with a clean surface — ideal for LED lighting, drivers and power modules.

Applications

Where It's Used

Radial and flat heat sinks, LED bar profiles, driver housings and automotive power-electronics coolers. The radial heat sink in our gallery is a real part extruded with a KALEKS die.
