Xiaomi on Friday, November 5 announced a new technology called Loop LiquidCool, which it says will ensure efficient cooling of smartphone processors. The heat dissipation method introduced by the Chinese smartphone giant is claimed to separate hot air and cool liquid circulation which alleviates the issues of low heat convention on mobile phones. Inspired by cooling systems used in aerospace technologies, the Loop LiquidCool Technology is a new take on the traditional vapor chamber. It works based on the capillary effect which draws liquid cooling agents towards the heat source, evaporates, and then dissipates the heat towards a cooler area. The company is planning to pack Loop LiquidCool technology in its smartphones in the second half of 2022.
Xiaomi Display New Loop LiquidCool Technology via a blog post. The company claims that the new technology delivers twice the cooling capacity compared to conventional vapor chambers (VC) solutions. Loop LiquidCool Technology includes an annular heat pipe system consisting of an evaporator, a condenser, a refill chamber, gas and liquid pipes. When there is a significant workload for the smartphone, the refrigerant in the evaporator evaporates to become a gas. The gas and air flow then expands into the condenser where the gas further condenses into a liquid. These fluids are absorbed and collected through tiny fibers in the refill chamber, making it a self-sustaining system.
Xiaomi says that the new technology uses a similar method to VC liquid cooling. Nevertheless, traditional VC systems do not have separate channels for gases and liquids. In Loop LiquidCool Technology, the pump features a special gas pipe design that is claimed to reduce air passage resistance by up to 30 percent and increase heat transfer efficiency by up to 100 percent.
With the Tesla valve microstructure, one-way circulation is said to prevent heat from moving backward and increase the heat dissipation capacity of standard vapor chambers.
Xiaomi too Illustrated The new method on the custom Xiaomi MIX 4 by replacing the original vapor chamber with the new Loop LiquidCool technology solution. The company claimed that for 30 minutes of Genshine Impact running at 60 frames per second (fps) and maximum graphics settings, heating was no more than 47.7 °C and the processor was 8.6 °C lower than the standard version.
