In a two-phase flow cooling system, heat generated in electronic devices (CPU, GPU, etc.) is dissipated by evaporation of a working fluid. This advanced thermal management solution is capable of dissipating larger heat loads compared to the available traditional methods (liquid cooling or heat pipes) in a more efficient way.

In Quattro proposes an innovative and advanced thermal control system based on two-phase pumped loop.
There is a loop with a pump to circulate a working fluid. Downstream the pump, the fluid flows to an evaporator, the cold plate where liquid evaporates and heat from the electronic device (CPU or GPU) is being absorbed. The vapor then flows to a condenser where it is condensed back into liquid phase and heat is released from the fluid to ambient or to heat sink. The fluid is a dielectric fluid with low boiling temperature.

This innovative thermal control system will be able to remove high power densities with low mass flow rate and maintaining the surface of the electronic component isothermal. A two-phase cooling system takes the advantage to transfer the thermal energy through the latent heat of vaporization and this leads to lower mass flow rates and as consequence lower pumping power compared to liquid cooling systems.
Beside this advantage, the system has lower volume and mass compared to classical cooling methods and requires less energy.
