Why Sustainability Matters in Power Electronics Thermal Management?

As electrification accelerates, sustainable technology solutions are no longer optional — they are essential. As industries drive toward electrification, renewable energy, and energy efficiency, thermal management plays a decisive role. CooliBlade’s NEOcore™ technology represents a breakthrough in sustainable power electronics cooling, delivering both environmental benefits and superior thermal performance across the entire lifecycle.

Sustainable Materials with Advanced Performance

At first glance, NEOcore resembles a conventional aluminum heat sink — but inside lies its innovation. The integrated thermosiphon channel transforms standard aluminum into a high-efficiency cooling solution capable of replacing copper heat pipes and complex liquid cooling systems.

Key sustainability features include:

• Pure aluminum construction → lightweight, abundant, and infinitely recyclable without loss of properties, supporting the circular economy.
• Environmentally safe working fluid → free from F-gases, ozone-depleting substances, or global warming potential.
• Elimination of copper and brazed heat pipes → reduced raw material dependency and lower lifecycle emissions.

Cleaner, Safer, and More Efficient Manufacturing

NEOcore is manufactured with mechanical assembly methods, avoiding energy-intensive or polluting processes.

• No soldering, brazing, or high-temperature heating.
• No harmful chemicals or flux agents required.
• Minimal waste generation, particularly in ULTIMA and AURORA product platforms.
• Improved worker safety and a cleaner manufacturing environment.

This production model ensures that sustainability is built in from the ground up.

Cascading Environmental Benefits

By enhancing thermal performance, NEOcore enables multiple sustainability advantages throughout product use:

• Extended component lifespans → reduced electronic waste.
• Improved energy efficiency → lower operating costs and reduced carbon footprint.
• Reduced material usage → up to 50% lighter than standard aluminum heat sinks.
• Smaller or slower-running fans →
  • Lower power consumption
  • Extended system lifetime
  • Reduced air filter replacements and less waste
  • Lower noise emissions → healthier workplaces and less noise pollution
• Reduced transportation emissions → thanks to lower cooling system weight and volume.

Product Platforms: ULTIMA & AURORA

• ULTIMA platform → Combines exceptional cooling performance with a minimal environmental footprint. Its design supports recycled aluminum, enabling further CO₂ reductions without compromising reliability.
• AURORA platform → Tailored for high-volume applications. Direct extrusion of NEOcore channels into aluminum profiles achieves up to 50% better performance than traditional extruded aluminum heat sinks — while maintaining cost efficiency.

Conclusion: Sustainability Without Compromise

With NEOcore power electronics cooling solutions, organizations can significantly reduce their environmental impact while improving thermal management efficiency.

By combining:

• Sustainable materials
• Clean manufacturing processes
• Lightweight, compact designs
• Superior performance in IGBT and SiC power module cooling

CooliBlade proves that environmental responsibility and technical excellence can go hand in hand.

As electrification accelerates and industries face stricter sustainability targets, NEOcore sets a new standard for sustainable thermal management solutions — enabling a greener, more reliable, and more cost-efficient future for power electronics cooling.
