Two-phase heat transfer systems are widely used in computer technology for cooling the chipset. A striking example of such systems are heat pipes and vapor chamber. Within these products there is a liquid that evaporates, it absorbs the latent heat of vaporization (in most liquids, it is much higher than the heat capacity). In this case the vapor pressure is greater than the cavity in the condenser due to the temperature difference between them, where the conversion to a liquid gives the latent heat, which dissipates heat in the environment. The resulting condensate is returned to the liquid chamber due to the action of gravity , closing the evaporation-condensation cycle of heat transfer.
It is easy to calculate that if you get a larger volume of fluid to evaporate, the effectiveness of the two-phase heat transfer system will proportionally increase. However, so far experiments on the creation of large two-phase heat exchangers suitable for use in computer technology have been unsuccessful.
Auras products are widely used for removing excess heat from the notebook. A prototype two-phase cooling has been shown during the exhibition Computex, but for unknown reasons, published only this week.
The prototype is able to take from the CPU up to 240 watts of thermal energy. The small tube in the bottom of the cooler enters a liquid that evaporates at a larger diameter tube is returned to the condenser as a vapor. .
