Smartphone chipsets keep getting faster every year, but despite continued improvement in silicon nodes, they keep running hotter too. This is why cooling technology in smartphones is handy at this time.
Xiaomi has introduced Loop LiquidCool Technology for smartphones which promises twice the cooling capabilities compared to conventional vapor chambers solutions.
How Does it Work?
This 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. This liquid then goes to the Refill chamber that feeds the Evaporator, so the cycle can begin anew.
This new technology uses the same method as VC liquid cooling, this uses ring-shaped pump features a special gas pipe design, which greatly reduces air passage resistance by 30% for a smoother steam flow, so the maximum heat transfer capacity is increased by up to 100%.
The second major change is the use of Tesla valves to ensure that the circulation goes the right way. Yes, these valves were invented by that Tesla and have no moving parts, instead they rely on their clever design to ensure that liquid flows much easier in one direction than the other (they are easy to recognize by the string of teardrop shapes).
Xiaomi said, 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.
Xiaomi says that its design is flexible and can be made to accommodate other components, e.g. a square-shaped loop would leave more room for the battery, camera modules and other components.
The company plans to introduce the Loop LiquidCool Technology in its smartphones in the second half of 2022.
