Pressed fin LED Heatsink

Heatpipes and Systems for High Thermal Performance

High Power LED Applications


DAU STC LED Heat sinks are designed to provide the optimum compromise between high surface area and areodynamics.

This design ensures adequate cooling of the LED module even for the case of no forced convection in the air. Furthermore, a heat spreader with a flat contact area ensures that the heat from the module will be transfered as efficiently as possible into the Heatpipe and then further on into the fins.The contact block is machined flat and the module can be fixed with screws to the contact block.

Advantages of the DAU LED cooling units are compact sizes, zero noise level, long life spans and easy installations.
