Xiaomi phone official microblogging today posted an article for Xiaomi 13 Ultra warm-up, announcing that it will be equipped with self-research ring-shaped cold pump cooling technology. The technology is designed with gas-liquid separation and a unidirectional internal circulation structure, which allows for a more efficient heat dissipation cycle while greatly increasing the speed of the cold liquid transfer, and increasing the heat dissipation capacity by 300% compared to traditional VC.

The official article of Xiaomi was issued again to further explain the “ring-shaped cold pump” technology.
The official from Xiaomi that the so-called “ring cold pump” technology is through a unique multi-layer water control one-way structure, using the principle of nature’s capillary force, the distal coolant pumped to the hot zone, the liquid evaporated in the hot zone by heat and will be conducted down to the cold zone, to achieve a clockwise one-way cycle. Ultimately, the next-generation cooling technology with an equivalent thermal conductivity three times that of traditional VC is made. And the Xiaomi ring-shaped cold pump is definitely a revolutionary upgrade in the history of mobile cooling!
In addition, Xiaomi officials said that the reason why they did not choose to directly increase the area of the VC homogeneous thermal plate on the Xiaomi 13 Ultra but chose to redesign the cooling structure of the ring-shaped cold pump is that the traditional VC can not be increased indefinitely. As the VC area increases, the internal vapour and liquid will clash, resulting in lower heat dissipation efficiency.
Coupled with the rapid development of cell phone imaging technology, the power consumption in terms of imaging is also rapidly increasing with the rapid increase, even without losing large 3D games. Especially the Xiaomi 13 Ultra, which has fully optimized imaging capabilities, has even more stringent requirements for imaging system heat dissipation. In this case, Xiaomi through the “vapour-liquid separation” and “one-way circulation” two key technical innovations, references the aerospace satellite cooling method to develop a more suitable for the image flagship “ring-shaped cold pump “technology.
