Sapa Thermal Management offers you heat sink design, development expertise and resources, advanced simulation and measuring equipment plus a network of metal, mechanical, physical and chemical specialists to help you find the optimum cooling solution. We have designed heat sinks and coolers for a wide array of businesses from stacked liquid cold plates for power transforming and solar inverters to LED fixtures or PCB mounted units.

Main products are air heat sink and liquid cooler.

1  Air heat sink

Sapa has worked closely with many of its customers to optimize their heat sinks.  Using CFD analysis (FEM), Sapa has developed new technologies to control the airflow through the channels. As seen in the pictures to the left, the orientation of a natural convection heat sink has a strong impact on its cooling efficiency.

By manipulating the airflow between the fins, the loss of cooling capacity can be drastically decreased. In many cases, the result can actually be better than with a vertical orientated heat sink, which is considered to have 100% efficiency with regard to cooling capacity in relation to gravity.

2  Liquid cooler

Solutions specially designed for your needs
A combination of computational fluid dynamics, manufacturing and extrusion technology gives you a reasonable price and a thermal solution optimized to your specific heat dissipation requirements.

From MIG to FSW
A liquid cooling device that is now welded using the FSW method. This process
has just a few variables that are easy to control. It gives the same results weld after
weld. Fusion welding is a more complicated process, which means that results
often vary.
