more eVs expected to be sold in 2030 (31.1m) vs 2020 (2.5m).

This rapid growth is driving the increased use of power electronics and battery systems. Cooling is critical for power efficiency and lifetime in both applications. Calyos two-phase solutions offer the most sustainable cooling solution due to their inherently passive nature.

POWER ELECTRONICS

  • Converter
  • Inverter
  • On-Board Chargers

Power electronics are a core requirement for every e-mobility application. Power inverters and converters represent our primary application in all sectors, and the components that enable such systems are constantly increasing in power density. Our solutions are ready to meet this increased cooling demand, while also providing a safe, reliable, and proven solution.

batteries

  • Pouch Cell
  • Cylindrical Cell
  • Module / Pack

Batteries are a critical element in almost every e-mobility application. Thermal management is critical to prevent thermal runaway and keep the cells operating at maximum performance. Features such as ultra-fast charging can put the cells under extreme thermal stress. Calyos has solutions to ensure you have a long lasting high performance battery system.

embedded ELECTRONICS

  • Advanced Driver Assistance Systems (ADAS)
  • Electronic Control Units (ECU), CPU, GPU
  • Sensors: Radar, Lidar

Embedded electronics can be relevant to a host of different components that require specific cooling needs. In e-mobility the most common application is for advanced driver assistance systems and autonomous vehicle systems. As more high power computing elements are embedded inside vehicles innovative cooling solutions like ours are going to become the norm.

how does calyos resolve common thermal challenges?

Calyos has designed our two-phase thermal solutions to be easy to adopt, while resolving many of the common challenges faced by engineers today. Calyos encourages our clients to remain open minded in their approach. You can combine our solutions with other cooling systems or replace systems entirely, it's up to you. Calyos will work with you to resolve whatever challenges you face and you can be safe in the knowledge that two-phase, passive systems are the most sustainable cooling solutions on the market today.

easy to adopt

Our solutions are built from off the shelf components, connected by lines routed around other components, based on the mechanical design of your specific application.

fit & forget reliability

Our systems have no moving parts and every system is helium tested for tightness before it leaves the factory. Combine that with our dielectric fluid and the result is best in class reliability.

high Heat density

The latest components are forever increasing in total thermal power and heat density. Vaporising (two-phase) systems have a better ability to handle the highest heat flux than single phase.

small packaging size

Our compact solutions use thin and flexible lines to reach remote heat and cold sources without interfering with other components. Plus there is no pump to find space for.

micro channel heat pipe for batteries

UHP-BT

Placed in between cells, these tiny heat pipes can assist in both warming and cooling cells. The cross sectional shape can be completely customised and these solutions are incredibly cost effective to mass produce. Using a dielectric refrigerant inside removes the risk of short circuits, maintaining Calyos' fit-and-forget reliability.
