High-fin heat-sink profiles for LED and power electronics — balanced flow and clean surface on thin, deep fins.
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.
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.
Yes, with flow balancing for high-fin-ratio geometries we design dies that fully fill thin, deep fins.
Yes, we specialise in electronics cooling profiles including LED bar and spot heat sinks.
