What is the Nine Liquid Cooling Technology

The design concept of THE NINE liquid cooling technology comes from the principle and idea of traditional laptop cooling. It aims to provide the ultimate CPU & GPU performance with powerful heat dissipation capability, giving users a fast running speed and low temperature experience.

1. The 5mm diameter liquid-cooled tube commonly used on laptops is applied to the honor Note10 mobile phone, which plays the same role as the PC.

2. The liquid cooling tube is embedded in the large-area aluminum alloy frame of honor Note10, and utilizes the principle of the large-area aluminum alloy frame function as the heat sink on the PC. The frame size of the aluminum alloy is up to 177mm*85mm*0.9mm.

3. One end of the liquid-cooled tube overlaps the SOC, and the SOC heat is quickly transmitted, then the heat is quickly and evenly transmitted to the large-area aluminum alloy middle frame radiator. with the help of large-area graphite sheet, thereby performing rapid and effective heat dissipation.

Key features:

1. honor Note10 is a liquid-cooled pipe application user with the largest diameter (5mm) and longest length (113mm) in the mobile phone industry. The heat transfer power and heat transfer rate are the largest in the current mobile phone. Aluminum alloy large-size mid-frame radiators are also the largest in the mobile phone industry.

2. THE NINE PC grade liquid cooling. 9-layer three-dimensional heat dissipation, making heat dissipation capacity increase by 41%. PC-grade liquid-cooled tube, 5mm diameter flattened and 113mm length running through make the CPU temperature be reduced by up to 10 degrees.

How does honor Note10 load a large size liquid cooling tube under a thin body and ensure performance?

As part of the Huawei Daya Bay program, Huawei established a special group of liquid cooling tubes including 2012 laboratory thermal design experts and European research institutes Belarusian liquid cooling pipe experts.

In order to achieve the goal of ensuring stable heat transfer of more than 5W after the diameter D5 is flattened, the research team spent 6 months on design, simulation, trial production, test verification and mass production evaluation. After thousands of tests of dozens of test items, discard over 10,000 tubes. The team eventually lead products into commercial use.

Through the micron-scale capillary parameter calculation, the optimal micro-structure design of the liquid-cooled tube is obtained. The experts have accumulated experience in the two-phase field for decades to guide the development team to find the best working parameters and process parameters, and finally achieve the technical goals and jointly Industry chain partners quickly increase the yield of water cooling radiator to mass production levels.

In order to ensure that each user can get the best cooling experience, they have developed a great water cooling system, including performance standards, reliability standards, appearance standards, flatness standards, etc. To the final mobile phone mass production and shipment, the liquid cooling pipe of each mobile phone has undergone tests in all aspects to ensure that the mobile phone can run for a long time with high performance.
