Heat pipe cooling tower

Maximum cooling capacity for modern power electronics

Our Heat Pipe Cooling Tower is a vertical cooling system for power semiconductors such as SiC, GaN and MOSFET. It combines a compact design with high heat absorption capacity. It is particularly suitable for industrial systems, mobility solutions and systems with high power density. Even in retrofit applications, it delivers stable thermal results under constant installation conditions.

When performance increases, so does the thermal challenge

More powerful semiconductors such as SiC, GaN and MOSFETs are revolutionizing applications, but they generate massive amounts of heat. The space available for heat sinks also often remains unchanged. 
This results in numerous problems, which our Heat Pipe Cooling Tower can solve:

 

  • High power dissipation in SiC, GaN and MOSFET: These components generate large amounts of heat, which must be dissipated efficiently to ensure their full service life. Otherwise, the thermal load will lead to failures and reduce system stability.
  • Limited installation space: Many systems cannot simply be enlarged. It must be possible to integrate new cooling solutions into existing designs.
  • Retrofits and redesigns: It is often not possible to completely redesign existing systems. The cooling system must adapt, not the other way around.
  • Unreliable heat dissipation with vertical installation: Convection coolers lose efficiency when installed vertically, which can lead to local hotspots.
  • Complex maintenance and cooling fluids: Active cooling systems require pumps, seals and regular maintenance. This causes effort and costs.

The Heat Pipe Cooling Tower: The solution for compact, powerful cooling


The Heat Pipe Cooling Tower has been specially developed for applications where high power loss meets limited installation space. The high heat flux density of these components is absorbed by the base plate and the heat pipes and then dissipated evenly via the fins.

The vertical design utilizes the height instead of the surface area and thus creates thermal performance without additional volume. The integrated heat pipes transport heat quickly and evenly into the fin body, where it is released into the environment.

 

Thanks to the fully soldered construction of the Heat Pipe Cooling Tower, the system does not require pumps or cooling media. It operates silently, is maintenance-free and impresses with its long service life, even in continuous operation and with changing thermal loads.
