Active CryoFlux is basically a closed-loop liquid cooling system found in a desktop computer. The system, of course, has been greatly scaled down for a smartphone.
Active CryoFlux is based on a ceramic piezoelectric micropump that circulates fluid through a series of tubes. All this absorbs heat from the SoC. OnePlus claims that Active Cryoflux can reduce temperatures by up to 2.1°C. During charging, the temperature can be lowered by 1.6°C, reducing the charging time by 30-45 seconds.
It is unclear whether OnePlus will implement this technology in a production smartphone.
