New Delhi: In what it calls a breakthrough in heat dissipation, electronics giant Xiaomi has announced its proprietary Loop LiquidCool Technology, which, as compared to conventional vapor chambers solutions, has twice the cooling capabilities. Xiaomi intends to introduce the new Loop LiquidCool Technology to its products in the second half of 2022.

This technology has drawn inspiration from cooling solutions used in the aerospace industry. Loop LiquidCool Technology essentially uses a capillary effect that draws liquid cooling agent to the heat source, vaporises, and then disperses the heat efficiently towards a cooler area, until the agent condenses and is captured via a unidirectional closed looped channel.

What is Loop LiquidCool Technology

This proprietary technology by Xiaomi has 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 refrigerant that evaporates to gas when the smartphone is under high workload. The gas and airflow is 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, thus, making it a self-sustaining system.

Slightly different from conventional VC liquid cooling, these systems do not have separate channels for gases and liquids, hot gas and cool liquids mix and obstruct each other while, especially under high workload. "The ring-shaped pump features a special gas pipe design, which greatly reduces air passage resistance by 30%. By allowing for a smoother steam flow, the maximum heat transfer capacity is increased by up to 100%," the handset maker recently wrote in a blog post.

The company's new cooling design makes use of a Tesla valve structure within the refill chamber that lets liquid to pass through the evaporator while blocking gases from moving in the incorrect direction. This allows for a higher efficiency in gas or liquid circulation throughout the system.
