OnePlus Tiangong Cooling System
In a groundbreaking announcement, OnePlus has introduced its latest technological marvel – the Tiangong cooling system. The first device to boast this cutting-edge innovation is the highly anticipated OnePlus Ace2 Pro, slated for a grand debut in August.

The Tiangong cooling system incorporates a triumvirate of advancements: a vast heat dissipation area, state-of-the-art aerospace-grade heat dissipation materials, and a revolutionary space structure. The VC area sets a new standard, covering an impressive 9140mm², which surpasses the mainstream specifications of the industry’s single VC by over two times, making it likely the largest cooling VC in the market.
The use of aerospace-grade diamond thermal conductive gel and super-conductive graphite sets a new benchmark in heat dissipation materials. Compared to its predecessor, the new-generation diamond thermal conductive gel achieves a remarkable 60% increase in thermal conductivity. Meanwhile, the aerospace-grade super-conductive graphite boasts an impressive 41% enhancement in thermal conductivity, outperforming the conventional graphite used in the industry.
Notably, OnePlus’s new cooling system pioneers a one-of-a-kind aerospace-grade space cooling structure, featuring a one-piece dual-cycle cooling system. The system leverages increased working water capacity to absorb more heat and enhance the heat dissipation process through double-heat-zone gasification. This leads to a significant improvement in heat dissipation cycle speed, boosting equivalent heat dissipation by an impressive 50%.
Drawing inspiration from the design of aerospace rocket engine nozzles, OnePlus implements a double-circulation design and incorporates a Laval airway in its heat dissipation structure. This elevates the traditional planar heat dissipation to a new “spatial heat dissipation dimension,” resulting in unparalleled heat dissipation efficiency and conduction capacity, which can reach up to four times that of the industry’s traditional VC.
In official tests, the Tiangong heat dissipation VC exhibits exceptional performance, outperforming its competitors by 8.5°C to 12.8°C in the 6.5W scenario and 8.7°C to 14.4°C in the 8W extreme scenario. These impressive results further validate OnePlus’s claim of redefining the standards of heat dissipation.
The OnePlus Ace2 Pro, the flagship model equipped with the Tiangong cooling system, boasts a formidable 3.2GHz Snapdragon 8 Gen2 processor. In addition, users can indulge in a remarkable 24GB of LPDDR5X and a capacious 1TB of UFS 4.0 storage. The device flaunts a stunning 1.5K curved screen and supports blazing-fast 150W fast charging.
As OnePlus ushers in the “three-dimensional heat dissipation era,” they are pushing the boundaries of smartphone cooling technology to new heights. The Tiangong cooling system in the OnePlus Ace2 Pro promises a seamless and immersive user experience, ensuring optimal performance even under heavy workloads and demanding tasks.
