DATE:
Calyos has successfully completed our Calypow project, moving from TRL 1 to TRL 3.
In June 2020 Calyos started a research project to study and evaluate aluminium as material for the evaporator. This initial project was to develop the technology from TRL 1 to TRL 3. This included the development of a research prototype which proved the feasibility of making full aluminium evaporators. Calyos now intends to complete a follow up project to further increase the TRL level.
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 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. The aim will be to reduce the cost by over 75% and the weight by 50%, hence why Calyos intends to continue the development to raise the solution to TRL5.
Today, Calyos' loop heat pipe cooling solutions are very efficient and 100% passive but they are still too expensive and too heavy, especially for high volume markets which have demanding price requirements. This is an important target for Calyos that will enable market penetration. To compensate for the risk associated with innovation, this new solution must be offered at the same price as the solution to be replaced so that its competitive advantages are an important differentiating means to enabling adoption in the 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.

What
Calyos is one of the world's leading experts in two-phase (liquid to vapour) heat transfer technologies. Calyos has developed a number of solutions for three specific cooling applications; power electronics, processors and batteries. Calyos also develops custom solutions beyond those applications for example, engine oil heat recovery. Calyos primarily targets the E-Mobility and Computing markets, where electrification and data processing are creating ever-rising demand for new, disruptive thermal solutions.
When
Calyos was incorporated in 2014 and is a spin-off from Euro Heat Pipes (EHP) who successfully developed similar two-phase technology for the space industry. EHP was incorporated in 2001 and today holds a majority market share in the European satellite market. Airbus D&S is now the majority shareholder in EHP. Calyos has been developing the technology for ground applications. This has involved a considerable amount of research and development, including developing flat evaporators, switching the working fluid to a dielectric green refrigerant and working on real-world applications such as those mentioned above.
Where
Calyos is based in Charleroi, Belgium. Calyos operates a factory side-by-side with our engineering team at this location and currently all of Calyos' production comes from this factory. Calyos supplies its products all across the world, including Asia, North America, Europe and South America.
Who
At Calyos we are a diverse group of talented individuals galvanised by the pursuit of establishing our disruptive, sustainable technology in our target markets. Remaining curious enables continued innovation as we work together to achieve our mission.
How
Calyos is built around four core values:
1. Applied Knowledge: Our technology is worthless unless we can get in it out there in the market. We strive to apply our knowledge and experience to real world applications.
2. Better Together: We succeed together. We view everyone from our customers to our shareholders as part of our team. Without working together we are nothing.
3. Inherent Flexibility: No thermal problem is the same. Therefore we strive to build flexibility into not only our solutions but also our working practices. This allows us to evolve with the market.
4. R-R-Research: Nothing stands still. As experts in our field, we must continue to innovate. We can then return to our first point and re-apply these innovations to real world applications.
Why
Our mission is to solve the greatest thermal challenges by enabling the adoption of the best, passive two-phase cooling solutions. Ensuring and delivering a sustainable approach to thermal management in the data-driven and electrified world we are creating.
