Smartphone manufacturers are trying their level best to squeeze maximum performance out of their devices for many years in pursuit of very smooth gaming experience or chart-topping benchmarks. But with great power comes great heat and the traditional heat pipes as well as thermal paste can help a lot. But as the chips become more stronger we need some advanced cooling systems for the smartphones. In this regard, Xiaomi has announced its advanced Loop LiquidCool technology.
According to Xiaomi the new technology works on the similar principle to a vapor chamber liquid cooling system like we have seen on iQOO 7 Legend, where a working fluid is recycled through a closed-loop system. During the heavy tasks, the evaporator’s refrigerant will vaporize which will pull the heat away from the phone components in the process. The gas travels through a tube until it finds its way to the condenser where it turns back into liquid and the cycle repeats.
Xiaomi has included a Tesla valve structure in the new design that allows liquid to move in one direction while preventing gas from going in the opposite direction unlike traditional vapor chambers that lets two-way gas movement. This should enhance the efficiency of the technology with 30% reduction in air passage resistance and 100% increase in heat transfer capacity compared to VC. Xiaomi has taken it’s existing MIX 4 phone and replaced original vapor chamber with new Loop LiquidCool solution. Xiaomi claims that during the half an hour of Genshin Impact gameplay at 60fps, the device only hit a maximum temperature of 47.7℃ effectively keeping the processor 8.6℃ lower than with VC.
