Revolutionizing Power Converter Cooling: How to Cut Weight by 50% and Reduce Heat by 25 °C - Read the Full Case Study
As power electronics grow more compact and efficient, thermal management has become a make-or-break design factor. Traditional aluminum heatsinks and standard air cooling can no longer meet the demands of modern IGBT, SiC, and GaN converters, especially in high-power, space-constrained applications like renewable energy inverters, EV charging and industrial applications.
The Solution? CooliBlade NEOcore with Proven Customer Results. Advanced NEOcore cooling technology for power electronics delivers liquid-like thermal performance in a fully passive, sealed thermosiphon design — no pumps, no leaks, and zero maintenance – meaning significantly reduced costs. By efficiently moving heat away from high-density semiconductor hotspots, NEOcore allows engineers to increase power density while reducing operating temperatures by up to 25 °C. The result: lighter systems (over 50% weight reduction), simplified reliability, and lower total cost of ownership.
Why NEOcore is so Powerful for Power Electronics Design:
- Thermal Performance: Handle extreme heat fluxes in both IGBT and wide-bandgap devices without performance compromise.
- Lightweight & Compact: Drop-in solutions with over 50% lower cooling weight, ideal for space- and weight-sensitive applications like wind turbines and solar inverters.
- Maintenance-Free Reliability: Fully sealed, passive operation eliminates pumps, leaks, and service downtime.
- Versatility & Compatibility: Supports high-power density layouts, horizontal/vertical mounting, and easy integration with minimal design changes.
- Environmental & Lifecycle Benefits: No harmful refrigerants, compliant with EU F-Gas Regulation and US EPA restrictions, lower noise, extended equipment lifespan, and reduced operational costs.
