What is Xiaomi’s Loop LiquidCool technology?

 Every year, the power of smartphone chipsets increases, but they also get hotter due to the development of silicon chips.

Vapour chambers, also known as heat pipes, are a common part of the cooling stack as a result of the growing importance of cooling solutions.

The Xiaomi-developed Loop LiquidCool technology improves conventional heat pipes in two ways, doubling cooling efficiency.

What is the mechanism? (look at the chart above). The Evaporator segment, which is heated by the chipset, causes liquid to evaporate. The hot gas that results travels down a pipe to the Condenser, where it is cooled (for instance, by using the metal frame as a heat sink) and condensed back into liquid. The cycle is then restarted by sending this liquid to the Refill chamber, which feeds the Evaporator.

This is similar to what happens in a typical heat pipe, but there are important differences, as was already mentioned. First, the hot gas and cold liquid are maintained distinct. In heat pipes, the contact between the wick that carries the liquid and the chamber that the gas passes through limits the efficiency of the device.

The use of Tesla valves to guarantee proper circulation is the second significant change. These valves, which are easily identified by the string of teardrop shapes, were created by that Tesla inventor and do not use any moving parts to ensure that liquid flows much more easily in one direction than the other.

As many as 70 Xiaomi smartphones lose support

 Although smartphone manufacturers are trying to offer longer support for their models more and more often, this time still ends. Xiaomi has published a list of 70 Xiaomi and Redmi models that will no longer receive updates.

Among the manufacturers of Android smartphones, Samsung and Google offer the longest support for their devices. other vendors still stick to two or three years maximum security support and two major system updates. It is no different in the case of Xiaomi.

The Xiaomi Security Center has published an extensive list of devices whose support is just ending. this means they will no longer receive software and security updates. They are three-year-old or older models, and the latest smartphones to join them are the Xiaomi Mi 9 SE and Mi Play (the last system update included Android 11 and MIUI 12.5). Of course, it should be remembered that although devices from this list have fallen out of the update schedule, in the event of critical errors, the company will certainly issue an appropriate fix for them.

If you look at the list below, you can see that some older models are missing, such as Mi 8 and Redmi Note 7. Why? Here, the matter is simple, these smartphones were huge sales hits and apparently it is still not profitable to abandon them.
