In next-generation electronics, from AI servers and 5G infrastructure to optical networking and industrial automation, consistent thermal control isn’t optional; it’s essential to maintain performance, reliability and lifespan.
Two-phase cooling offers a highly efficient, compact, and reliable alternative that leverages phase-change heat transfer to move large quantities of heat with minimal temperature gradient. Radian Thermal Products designs and manufactures precision-engineered vapor chambers and heat pipe assemblies for demanding environments where traditional cooling methods are insufficient.
Two-phase cooling is a thermal management method that uses phase change — the vaporization and condensation of a working fluid — to transfer heat efficiently across a surface or distance.
Unlike solid or single-phase conduction, which relies on temperature gradients through metal, two-phase systems move heat through latent heat transfer, allowing rapid and uniform temperature distribution. This makes two-phase cooling particularly effective in:
Two-phase systems deliver superior heat transfer coefficients, improving performance over traditional conduction or convection-based designs. They support power densities up to ~ 300 W/cm² and uniform surface temperature minimizes hotspots and localized thermal stress
Lower PUE (Power Usage Effectiveness)
In data center and server environments, two-phase cooling systems contribute to lower overall energy consumption by reducing fan speeds and air-conditioning load.
By dissipating heat more effectively per unit area, two-phase systems support denser PCB layouts and higher component counts without additional cooling hardware.This puts less thermal constraints on design while increasing wattage performance.
Two-phase cooling devices are sealed, passive systems: no pumps, no moving parts, and minimal maintenance requirements over their operational life. That means long operational life cycle and high reliability in harsh or remote environments.
Radian’s portfolio supports both board-level and system-level integration, enabling customized solutions for new or retrofit designs:
Two-phase cooling represents a critical step forward in the evolution of thermal management, combining high performance, low energy demand, and exceptional reliability in a scalable form factor.
