Calyos products

Calyos specializes in cutting-edge two-phase cooling systems that leverage Loop Heat Pipes (LHPs) to meet high heat flux demands and transport heat over long distances efficiently. This passive heat transfer technology eliminates the need for fans or pumps, ensuring low power consumption, increased lifespan, and reduced weight. Calyos’ LHPs are designed to address the thermal management challenges in diverse applications such as batteries, electronic components, embedded processors, personal computers, power electronics, and servers. As electronic devices shrink and generate more heat, and as new technologies such as GaN and SiC revolutionize the power electronics market, effective thermal management becomes crucial. Calyos integrates advanced physics-based modeling and proprietary wick structures to optimize fluid dynamics and enhance vaporization and condensation processes. The manufacturing process, supported by both in-house facilities and strategic industrial partnerships, ensures that the cooling systems are cost-effective and scalable to meet mass production needs. The robust, maintenance-free designs provide reliable thermal management solutions necessary for modern, high-performance applications.

Micro Channel Heat Pipes (MCHPs) by Calyos represent a hybrid solution combining the best attributes of heat pipes (HP) and pulsating heat pipes (PHP). These lightweight and ultra-efficient cooling systems are designed to manage thermal loads across various applications, including batteries, embedded processors, electronic components, and more. As battery technology evolves and becomes more demanding, MCHPs address the increasing challenge of heat dissipation in battery packs, enabling faster charging and improved safety. In vehicles, where sophisticated software defines operation, MCHPs efficiently cool data center-grade processors subjected to harsh environments like defense and aeronautics. For miniaturized electronic components, these cooling solutions accommodate increasing heat production due to new packaging requirements. Calyos ensures the feasibility of integrating MCHPs into different systems through detailed thermal performance evaluations, robust mechanical design validations, and cost analyses. By leveraging proprietary wick structures, fluid selection, and fine-tuned vaporization and condensation processes, Calyos achieves high heat transfer coefficients and low thermal resistance, guaranteeing passive and pump-free operation with minimal maintenance.

Also referred to as Oscillating Heat Pipes, Calyos is working hard to mature this newer technology. Less reliance on gravity for operation. The latent heat of vaporisation has a high heat transfer co-efficient. Ability to operate in unique form factors (thin, 3D) with highly customised integration.
