If you’re in power electronics, you know the feeling. You’ve designed a next-generation system with powerful, efficient SiC modules, but you’ve hit a thermal wall. Getting the heat out has become the single biggest bottleneck preventing you from reaching your product's true potential. What do you do?
Stuck Between a Rock and a Hard Place
This was the exact situation one of our customers faced while developing a new megawatt-scale power converter. Their existing cooling solution, a massive 39 kg aluminum heatsink, just wasn't cutting it anymore.
They were left with two bad options:
-
Stick with an underperforming air-cooling system and throttle back their design's performance.
-
Embark on a costly, time-consuming redesign to integrate a complex liquid cooling system, adding a whole new set of risks, failure points, and maintenance headaches.
It was the classic engineering dilemma where every choice felt like a compromise.
A Breakthrough with a 'Plug & Play' Upgrade
Instead of compromising, they found a third option. By integrating the CooliBlade ULTIMA, a passive thermal solution powered by our NEOcore™ thermosiphon technology, they found a way to get the performance they needed without the complexity they wanted to avoid. This wasn't a system overhaul; it was a simple, plug-in upgrade that acted as a thermal superhighway, pulling heat away from their critical components with incredible efficiency.
The ULTIMA cooling solution
The Results: More Power, Less Heat, Zero Headaches
By upgrading their thermal management with the CooliBlade ULTIMA, the customer didn't just solve their overheating problem—they unlocked a new level of performance. The results, made possible by the integrated NEOcore™ technology, speak for themselves:
-
A 25°C drop in component temperature under the same loads.
-
A 50% reduction in weight, going from a 39 kg brick to a sleek 18.5 kg solution.
-
Zero system redesign, saving them months of development time and resources.
This project proves you don’t need the complexity of liquid cooling to handle high-power applications.
