Calyos has started Calypow 2 project


Charleroi, Belgium


November 29, 2022

Calyos has successfully secured funding for Calypow 2 project to move our technology from TRL 3 to TRL 5.

Calyos, a Belgian technology company focusing on a sustainable offering for thermal management within e-mobility, computing, renewable energy and specialized niches, is delighted to announce that Calyos has secured funding from the Walloon region to continue raising the level of aluminium in our loop heat pipe solutions.

With the rapid growth of electrified mobility, power electronics are a critical component providing power conversion or inversion. Applications include charging infrastructure and the powertrain itself. In tandem electronic providers are developing ever smaller components, utilising technologies like GaN and SiC. As they decrease in size they also increase in heat density requiring ever higher performance cooling systems.  For the e-mobility industry power-to-weight ratio is critical to maximise the range of such vehicles. Hence lightweight cooling systems are a demand from the industry.

The first Calypow project aimed to develop a more cost effective and lighter weight cooling technology from our existing passive high-performance loop heat pipe evaporators. This has involved developing an aluminum evaporator for the e-mobility mass market. The Calypow project has taken the first step in this direction designing and developing a research prototype that has increased TRL level from TRL 1 to TRL 3. Making the leap to aluminium will enable a more cost effective, lightweight solution compared to the existing copper and stainless steel solution currently in production.

Calypow 2 project aims to reduce the cost by over 75% and the weight by 50% to better prepare for scaling up in the automotive market.

Calyos is thankful to the Walloon region for supporting this R&D project to support Calyos' future. It should be noted that the results of this project may be used in our other market segments.
