Simple and reliable Profile heat sinks – the universal cooling solution

Aluminiumprofilkühlkörper

Aluminum profile heat sinks – also known as die-cast or extruded heat sinks, depending on the manufacturing process – are the classic method for cooling of power electronics. Their fins provide a large cooling surface for effective heat dissipation by means of natural convection. Profile heat sinks therefore ensure the stable operation of electronic components and a long service life. 

Applications range from cooling of semiconductors in small mobile end devices to cooling of high-power IGBTs in railway technology. There are different methods for mounting them on the electronic component to be cooled: Small profile heat sinks are mounted using clips or soldering pins. Large die-cast heat sinks generally have integrated threads for screwing them in.

Did you know that the cooling capacity of die-cast heat sinks can be increased by combining them with a fan or heat pipes?

Diversified

The potential applications for profile heat sinks are as diverse as the available heat sink geometries and sizes.

 

Reliable

Extruded heat sinks ensure reliable dissipation of large amounts of heat.

 

Low-cost

Once it is manufactured, one tool can be used to produce entire heat sink series at low costs per piece.

Optimization through CNC machining and surface finishing

The die-casting process inherently involves unavoidable tolerance deviations. However, this can be compensated by subsequent CNC machining according to drawings. Post-treatment optimizes the contact between the electronic component and the heat sink, in addition to reducing thermal transfer resistance and improving thermal conductivity. In addition to CNC machining, we also offer surface finishing by means of anodizing, powder coating, chrome plating or painting. 

If you have any questions about CNC machining and surface finishing, please feel free to contact us!
