Our vacuum-brazed heat sinks are specially designed for cooling high-capacity battery cells such as LTO, NMC, and LFP. These cooling technologies are tailor-made for industrial energy storage systems and mobile applications such as traction systems, buses, and construction machinery.
The heat sinks for battery cooling are manufactured using a vacuum brazing process. This involves placing a cover plate on a precision-machined or deep-drawn base plate and heating it in a vacuum brazing furnace at 580–600 °C.
A thin, rolled aluminum layer with a slightly lower melting point melts during this process, ensuring an extremely reliable, strong bond between the two components.
We offer two manufacturing options:

CFD-optimized channels ensure uniform battery cooling and prevent harmful hot spots.
Our cold plates perform a structural function – ideal for applications such as commercial vehicles and trains.
A flux-free vacuum brazing process ensures that the cooling plates remain extremely resistant and durable.
Minimal deformation of the plates reduces mechanical stress on sensitive battery components.
CO₂-reduced production and the use of recycled materials actively contribute to sustainability.
