THE NEXT GENERATION OF HEAT DISSIPATION
Inspired by cooling solutions used in the aerospace industry, Loop LiquidCool Technology utilizes a capillary effect which draws liquid cooling agent to the heat source, vaporizes, and then disperses the heat efficiently towards a cooler area, until the agent condenses and is captured via a unidirectional closed-looped channel. Compared to conventional vapor chambers solutions, this new technology has twice the cooling capabilities and ranks as the most efficient smartphone cooling solution. Xiaomi aims to bring Loop LiquidCool Technology to its products in the second half of 2022.
Loop LiquidCool Technology
This new technology features an annular heat pipe system that is composed of an evaporator, a condenser, a refill chamber, as well as gas and liquid pipes. Placed at heat sources, the evaporator has a refrigerant that evaporates to gas when the smartphone is under high workload. The gas and airflow are then diffused to the condenser, where the gas condenses into liquid again. These liquids are absorbed and collected through tiny fibers in the refill chamber—which refills the evaporator—making it a self-sustaining system.
One-way circulation is key to heat dissipation
To ensure one-way high-efficiency circulation, implementing a Tesla valve structure within the refill chamber is crucial. A Tesla valve is a one-way valve that allows liquid to pass through the evaporator while blocking gases from moving in the incorrect direction. This allows for higher efficiency in gas/liquid circulation throughout the system.
Xiaomi Mix 4
On a custom Xiaomi MIX 4, the original vapor chamber was replaced with a new Loop LiquidCool Technology solution. During a 30-minute Genshin Impact gameplay test running 60fps max video settings, this impressive cooling system kept the device below a max temperature of 47.7℃ and the processor was 8.6℃ lower than the standard version.
