On Tuesday, Wednesday (August 14-15), Glory Note10 launched the journey of exploring the NINE liquid cooling technology. The YORK mobile phone channel was invited to join the media colleagues to enter the Daya Bay Nuclear Power Plant and the Institute of Research. Fortunately, Zhao Ming, the president of the Quest, visited the site and visited the Daya Bay Nuclear Power Station in Shenzhen to learn more about the heat dissipation principle of the Daya Bay Nuclear Power Plant. During the event, President Zhao Ming shared the origin of the 'Daya Bay' project and THE NINE solution. The principle of cold cooling technology.
Glory Note10 THE NINE Liquid Cooling Quest
Zhao Ming, President of Glory, said that there is a project team named "Daya Bay" inside the glory. The technical team consisting of the CPU Turbo team and the cooling team is dedicated to overcoming the technical difficulties of CPU performance optimization and improving the heat dissipation capability of the mobile phone. Not only that, 70%-80% of the hardware design and system architecture design of glory are involved in this project team. The inspiration for THE NINE liquid cooling technology for the first time of Glory Note10 is also derived from the technical concept of Daya Bay Nuclear Power Station.
As we all know, the Daya Bay Nuclear Power Station is good at using natural energy, and the water cycle plays a vital role in it. It is inspired by this that glory Note10 first launched THE NINE liquid cooling technology, placing only 5mm diameter liquid-cooled pipe in On the mobile phone. Based on this, it naturally promoted the technical exchange meeting between the glory and the Daya Bay nuclear power plant.

On the 15th, after the communication meeting of the Daya Bay Nuclear Power Station, the author and his team came to the Institute of Wuyan to further understand the deep technical principles of THE NINE liquid cooling technology.
Previously, due to the experience of glory Note10, I still have some understanding of the heat dissipation of this product. But the detailed working principle of it only knows it but I don’t know why. In the Institute of Mechanical Engineering, the technical engineer performed the on-site demolition of the glory Note10 real machine. Solution, complete and detailed presentation of the glory Note10 in THE NINE liquid cooling, dual Turbo and other technology research and development process and industry technology advantages.
Glory Note10 THE NINE liquid cooling system
It is reported that the THE NINE liquid cooling technology adopted by Glory Note10 was set up by the 2012 laboratory to set up a special thermal design team. After 6 months, more than 10,000 heat pipes were scrapped, and the liquid cooling system was finally formed. Breakthrough, successfully dipped the D5 liquid cooling tube with the same diameter as the MacBook Air liquid cooling tube (5mm) into the body of only 7.65mm thick, up to 113mm while longitudinally crossing the hot and cold areas, covering the most The whole machine is scientifically cooled. It is understood that this size is the longest liquid-cooled tube design of all mobile phones.
Liquid cooled tube scrapped in the experiment
The liquid-cooled pipe structure is mainly composed of a casing, a wick, and a working fluid. It is functionally divided into three parts: an evaporation section, an adiabatic section and a condensing section. The working principle is as follows: When the liquid-cooled tube evaporation section is heated, the area is wicked. The liquid in the vapor evaporates and takes away a large amount of heat. The steam flows to the condensation section under a slight pressure difference, and condenses into a liquid after releasing heat in the condensation section, and the liquid returns to the evaporation section by the capillary force generated by the wick. A heat conduction cycle is completed to form a two-way circulation system in which steam and liquid coexist. The liquid cooling tube rapidly transfers the heat of the heat generating object to the outside of the heat source, and its heat conductivity exceeds the heat conductivity of any known metal.
Liquid cooling tube working principle
The actual thermal conductivity test of the liquid-cooled tube is much more efficient than ordinary copper tubes.
A deeper technical exploration found that the THE NINE liquid cooling system is different from the conventional heat sink system only with traditional silicone grease and motherboard. Glory Note10 also optimizes the heat dissipation for almost all structures in the mobile phone, successfully creating 9 layers. Three-dimensional cooling system. After the CPU of Glory Note10 is running, a part of the heat passes through the heat-dissipating grease, the copper alloy shield, the copper piece, and the solder is transferred to the heat pipe evaporation section. The heat pipe quickly transfers the heat of the CPU to the cold zone of the whole machine, and passes through The aluminum alloy uniform temperature plate and the large-area graphite sheet quickly dissipate the heat transferred to the cold zone. The other part of the heat of the CPU is heated by the PCB, and then radiated to the large graphite piece of the back shell, and the back shell is evenly heated. Avoid local hot spots in the shell.
Glory Note10 THE NINE liquid cooling concept
The liquid-cooled tube and graphite sheet with a diameter of 113mm are the longest and largest in the industry. It forms the best liquid-cooled tube layout and heat dissipation path in the industry, which increases the heat dissipation capacity of mobile phones by 41%. The scene CPU can be reduced by up to 10 ° C, solving the heat dissipation problem in all directions.

The performance and heat dissipation of mobile phones is an eternal topic in the development process. As long as we are still pursuing higher performance, mobile phone cooling must be a barrier that cannot be bypassed. The glory Note10 with dual Turbo and THE NINE liquid cooling technology Undoubtedly the best work on this issue. The glory and technology sharing of the Daya Bay nuclear power plant can be said to be the first time for the industry to see the advanced nature of science and technology cooperation. The 'Daya Bay' project also allows consumers to see Glory's R&D strength. As the first brand of domestic Internet mobile phone, the technical strength of glory has made it a leader in the mobile phone industry.
