Xiaomi just unveiled possibly the next major step in smartphone cooling—Loop LiquidCool

Breaking new grounds in the mobile tech industry is always exciting for us mobile tech nerds out there, no matter which company stands behind it. In that light, Xiaomi might have just revealed a groundbreaking innovation in smartphone cooling technology called Loop LiquidCool. The company claims its Loop LiquidCool solution can outperform traditional vapor chamber ones, and by no small margin at that.

Allegedly, this new cooling solution is twice as effective as the vapor chambers found in some of the best Android smartphones on the market. “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," explains Xiaomi in its announcement.

What makes Loop LiquidCool better?

If it sounds very similar to a vapor chamber to you, that’s because it is. However, there are a few key differences that Xiaomi says allow it to perform much better. For example, the Loop LiquidCool cooling system uses two channels to separate the liquid from the gases. Vapor chambers, on the other hand, use just one channel, which can cause the two substances to get into each other's way.


Another crucial part of the new cooling system by Xiaomi is the addition of a Tesla valve structure inside the refill chamber. It has a two-task job—to allow the liquid to pass through the evaporator and stop the gases from doing so. The company claims the Tesla valve structure makes the new cooling system more efficient in gas/liquid circulation.

Additionally, Loop LiquidCool technology also has a ring-shaped pump, which can lower air passage resistance by 30% thanks to a special gas pipe design. At the same time, it increases the maximum capacity for heat transfer to 100%.

The benefits of Loop LiquidCool technology

All of this witchery mumbo jumbo Xiaomi has done to make the Loop LiquidCool work is “cool” and all, but what are the results? Well, first and foremost, let’s talk temperatures, as this is the area we expect to see signs of progress.

To showcase the benefits of its innovation, Xiaomi put the Loop LiquidCool technology inside a custom-made MIX 4. The results shown in the provided image are no small feat—the phone equipped with Xioami’s new cooling system shows a drop in temperature by a staggering 15.48°F (8.6℃). For context, the regular MIX 4 went up to as much as 117.8°F (47.7℃).


While a lower temperature and more efficient cooling are what the new Loop LiquidCool technology brings to the table, there is actually one more benefit worth mentioning.



Yes, if the news of a better cooling system for smartphones wasn’t good enough, it also frees up more space for other components inside. Hopefully, that means even better cameras and more battery life for us users.

Xiaomi says it plans to release its first handset with the breakthrough tech sometime in the second half of 2022. If all the claims prove to be true, other Android phones could very likely start adopting this new method of cooling as well.
