Strong performance High-performance heat sinks from CTX

Hochleistungskühlkörper für Elektronik

High-power electronic assemblies, such as those used in drive technology or frequency inverters, must be cooled to protect the power semiconductors against overheating and failure. Our application-specific high-performance heat sinks provide a typical cooling solution for this requirement. Combined with a fan for forced cooling, the very compact and high-performance heat sinks are an inexpensive alternative to liquid cooling systems. 
 

Contact

Large surface area

High-performance heat sinks feature very high fin density, resulting in a very large heat sink surface area.

 

Highly efficient

High-performance heat sinks are up to 40 % lighter, more economical and smaller than conventional die-cast heat sinks.

 

Diversity of processes

We use different production processes depending on the required properties and quantities of high-performance heat sinks needed.

 

Individual tailor-made cooling solutions

Many high-performance heat sinks have a modular design. The heat sink base and cooling fins are either bonded, cold welded or brazed. Other typical manufacturing processes are press-fitting of the cooling fins in the base (crimped fins), paring of the fins from a metal block (skived fins), cold extrusion and friction stir welding.

Which process is used is determined on the basis of the particular application: required cooling capacity, available installation space and the number of heat sinks to be manufactured.

High-performance heat sink with modular design

The modular design allows the configuration of individual heat sinks with high fin density and long cooling fins on the basis of pre-fabricated standard modules. Three processes are used for joining the single elements to create a high-performance heat sink: brazing, friction stir welding and crimping.
 

The advantages of modular high-performance heat sinks at a glance

  • Large choice of standard modules
  • Configurable for the specific application
