LAGOS – July 26, 2022 – Today, Infinix officially launched its revolutionary 3D Vapor Cloud Chamber (3D VCC) Liquid Cooling
Technology. Using innovative design on the dimensionality of VC shape for the first time, designers have achieved an increase in the
chamber volume, which significantly improves heat dissipation resulting in better performance. This creative solution fixes some
issues caused by high temperatures for high-integration and high-power smartphones, such as CPU frequency reduction, frame rate
drops, and frozen screens. This new technology has been certified by the China National Intellectual Property Administration.
“Regular smartphone gamers players care about performance, while advanced players emphasize heat dissipation due to its direct
impact on performance. As the 5G era poses new challenges to the heat dissipation technique, technology development drives
innovations from traditional heat pipes to VC, a leap from line to surface basis, and now further upgrades from a flat surface to a
three-dimension basis to form Infinix 3D Vapor Cloud Chamber Liquid Cooling. This technology not only exhibits Infinix’s technical
foundation and innovative spirit but also represents a huge step towards technological progress. ” said Manfred Hong, Senior Product
Director of Infinix.
Infinix’s Self-Developed 3D VCC Technology
When heat enters the VC, water in the evaporator is vaporized into steam, which removes excess heat. Hot steam then flows into the
condenser, becoming a liquid, which flows back to the evaporator through the internal wick structure that forms a hot and cold
circulation system with the coexistence of water and steam.
When compared with traditional VC design, the 3D Vapor Cloud Chamber Liquid Cooling Technology has come a long way forward.
Bumps were added to one side of the evaporator, increasing chamber volume and water storage capacity along with thermal flux.
Water injection volume and Q max values increased by 20% when compared with conventional VC[1] resulting in massive
improvements overall.
Reducing the thermal resistance media of the heating source is realised by adjusting the structure of the front housing to form a bump,
which enables the 3D Vapor Cloud Chamber to almost directly contact the SoC chip. This significantly reduces thermal resistance from
shield to Vapor Chamber increasing thermal conductivity rate, performance, and heat dissipation. In comparison to traditional 2D
designs, the new 3D VCC reduces the temperature by about three degrees[2], and the total heat dissipation performance is increased
by about 12.5%[3].
The Challenges of Creating Perfection
For Infinix to master heat dissipation in the new 3D VCC design, structural strength needed to be vastly improved upon previous
designs. After numerous tests and improvements, Infinix’s R&D team designed the 3D internal structure into a matrix support
column, balancing flatness and internal chamber volume.
The second major challenge was to maintain the integrity of the wick structure within the 3D structure. Traditional VC wick structures
are flat and folds can easily occur within the 3D Cloud transition area, causing a potential chamber blockage. Utilizing a complicated
capillary structure density analysis and advanced welding technology, Infinix’s R&D team were able to ensure the integrity of the wick
structure, greatly improving performance.
Front housing adaptation was also taken into account. In order to reduce the thermal resistance medium, Infinix’s R&D team
repeatedly evaluated the position of the front housing opening and the strength of its alloy material, resulting in front housing
adaptation. Together, these key components make up Infinix’s self-developed 3D Vapor Cloud Chamber Liquid Cooling Technology.
With this technology embedded into Infinix smartphones, users can enjoy the benefit of superior performance when their device is
under heavy load, allowing them to play games harder and faster, live-stream for longer and reap the rewards of a cooler, smoother
running high performance smartphone.
Following its motto of “The Future is Now”, Infinix will continue to develop its smartphone heat dissipation technology. Infinix will
develop thinner VCs with more bumps, with more creative material processes, and even merge the smartphone middle frame and 3D
VCC into one, or to miniaturize the entire computer cooling module into the smartphone. Driven by a global vision, Infinix will
continue to deliver amazing products to consumers with its strong innovation capabilities giving them the best possible smartphone
within their price ranges.
