What Happened
Valeo and Calyos have signed a Memorandum of Understanding to develop and industrialize high-performance, standalone chip cooling solutions for mobility and computing. The passive two-phase cooling systems combine Calyos' Loop Heat Pipe technology with Valeo's thermal systems engineering and global manufacturing scale, aiming for compact, maintenance-free, and reliable solutions.
- Power electronics: autonomous cooling for on-board chargers, inverters, and integrated power electronics.
- Software-Defined Vehicles: standalone heat dissipation for centralized computing controllers with high power density.
- Data centers: energy-efficient two-phase cooling without active pumps, easy to retrofit into existing air-cooled servers.
“This cooperation with Calyos is a new step in our mission to lead the thermal management revolution. By integrating Calyos' Loop Heat Pipe expertise into Valeo's industrial ecosystem, we provide our customers in both the automotive and data center sectors with a unique cooling solution that is easy to integrate and scale, while significantly enhancing energy efficiency to support a more sustainabl”
Why this matters
As AI and vehicle electrification increase chip heat density, this collaboration aims to deliver more efficient, compact, and maintenance-free cooling, addressing thermal management challenges in computing and mobility.
