Infinix’s cutting-edge 3D vapour cloud chamber liquid cooling technology


Published : 06 Aug 2022 06:57 PM

Hong Kong-based smartphone brand, Infinix Mobile, has recently launched its revolutionary 3D Vapor Cloud Chamber (3D VCC) Liquid Cooling Technology to lead the smartphone industry with its brand spirit to empower the lives of today’s youth so they can challenge the norm and stand out from the crowd all around the world. Designers have achieved an increase in the chamber volume using innovative design on the dimensionality of VC shape for the first time. This 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 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 resulting in massive improvements overall.

Reducing the thermal resistance media of the heating source is realized 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, and the total heat dissipation performance is increased by about 12.5%.

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 maintaining 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 adaption was also considered. 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 if a cooler, smoother running high performance smartphone.
