Valeo, a global leader in automotive technology, and Calyos, a pioneer in passive advanced dual-phase loop heat pipe (LHP) cooling solutions, have announced the signing of a Memorandum of Understanding (MoU). This agreement aims to address the increasing thermal management challenges posed by electrification and artificial intelligence (AI) and to develop and produce high-performance, standalone chip cooling solutions for the mobility and computing sectors.
By combining Calyos’ expertise in loop heat pipe technology with Valeo’s world-class thermal systems engineering, manufacturing scale, and global network, the two companies will deliver a new generation of passive advanced dual-phase cooling systems that more efficiently manage high heat flux, are compact, easy to integrate, maintenance-free, and highly reliable.
Responding to the future of mobility
As the electrification of automobiles continues to expand on a massive scale and software-defined vehicles (SDVs) advance, the computing power and heat generated by power electronics are increasing exponentially.
Valeo and Calyos‘ passive two-phase cooling solutions offer the following benefits:
- Power Electronics: Autonomous cooling for on-board chargers (OBCs), inverters, and “x-in-1” integrated power electronics, providing a compact, standalone, “plug-and-play” cooling system. For electronics located at the rear of the vehicle, this solution brings energy savings and simplifies the vehicle’s cooling architecture.
- Software-Defined Vehicle (SDV): The SDV architecture drives the centralization of computing controllers with high power density requirements. The two companies’ solutions enable standalone, compact, and reliable heat dissipation optimized for high-speed processors, providing reliable and easily integrated cooling without the complexity of traditional distributed vehicle liquid cooling loops.

Innovating data center cooling efficiency and AI scalability
Valeo is applying decades of expertise in automotive thermal management to the data center industry, providing a comprehensive and scalable ecosystem of cooling solutions.
This collaboration extends beyond the mobility sector, targeting the rapidly growing data center market. The acceleration of AI is driving increased power consumption in data center racks and chips, and the demand for direct-to-chip liquid cooling, creating an urgent need for better cooling efficiency to reduce global energy consumption (PUE).
One of the first joint solutions from both companies, a smart two-phase passive chip cooling solution for data centers , offers the following:
- Energy efficiency: The two-phase loop heat pipe effect accommodates higher processor power and heat flux requirements, operating without moving parts such as pumps.
- Ease of retrofitting to air-cooled servers: Standalone dual-phase loop heat pipe air cooling units can be installed for each individual server in a rack, allowing data centers to upgrade power density through direct-to-chip cooling without overhauling their entire facility infrastructure.
- Reliability and compactness: A passive, highly efficient two-phase cooling system that simplifies maintenance (no drive fluid pump) and reduces the risk of leaks compared to conventional water cooling methods (low dielectric fluid pressure).
Xavier Dupont, CEO of Valeo Power Division , stated: “This collaboration with Calyos is another step in our mission to lead the thermal management revolution. By integrating Calyos’ loop heat pipe expertise into Valeo’s manufacturing ecosystem, we will provide customers in both the automotive and data center sectors with a unique cooling solution that is easily integrated and scalable, and significantly improves energy efficiency to support a more sustainable future. This new technology perfectly complements our existing portfolio of thermal management solutions for data center and automotive power electronics.”
Antoine DE RYCKEL, CEO of CALYOS, and Olivier DE LAET, founder of CALYOS, added: “Partnering with Valeo will elevate our technology from a niche innovation to a global industrial standard. Valeo’s manufacturing capabilities and thermal management expertise will be the perfect catalyst to meet the cooling needs of the AI era and next-generation electric vehicles.”
