Toys, virtual reality, and movie lovers can ease a break. Huawei patented this year with Cambridge University with an innovative solution that will solve the problem of overheating smartphones. Improving graphene, eliminating some of the undesired side effects, engineers promise that a patented solution will soon be deployed to all of the company's devices. Otherwise, the new cooling solution has already been applied to one of the leading series of the Mate 20 series, which saw the daylight in October this year.
Striving for excellence and providing customers with the most advanced technologies, manufacturers encourage continuous investment in the creation and development of innovations. Over the past decade, Huawei has invested more than 44 billion in research and development. Euro Based on these studies, the company has developed various solutions for solving problems with smart equipment.
According to Ianfei, the head of the Huavei Baltic Consumer Group, a solution for overheating overheating equipment was long sought. According to him, this problem arose as the needs of people are growing when the phone starts to use all intense activities related to resources, such as gaming or virtual reality.
"Earlier, the development of games for the smartphone did not require a huge capacity, but with the ability to play on the Internet with other people, the requirements of game makers and phone manufacturers began to be more demanding. Moreover, virtual platforms for additional reality that require high graphics capacity also get momentum in As the graphics capabilities of smartphones are often limited, there is a problem with cooling equipment, but that's the solution, "says Ianfei.
According to him, engineers of a company with scientists from the University of Cambridge have drawn attention to graphene. With its excellent thermal characteristics, this carbon form has become the basis for the development of thermal foils designed to increase the thermal conductivity of the device. True, it was not so easy before patenting the mentioned innovations.
Grafen had to get better
Graffen can best be described as a thin layer of graphite or a carbon nanomaterial with high thermal conductivity. Some scientists call it "the king of modern materials." According to Ianfei, you do not have to ask for that name, because the graphene consumes four times more efficient heat than any other alloy and ten times better than copper.
Although graphene, like nanomaterials, has excellent properties, its use also causes certain problems. For example, its conductivity can cause short or unwanted reactions during contact with other materials. Therefore, a team of Huawei engineers headed by Nobel Prize winner Constantin Novoselov and a team of scientists at the University of Cambridge have developed improved or so-called. Functionalized chart.
"The functionalized graphon has one or more active molecules embedded on its surface, which prevents various adverse reactions with other materials while maintaining excellent electrical and thermal conductivity characteristics." "That's precisely what we managed to achieve when we developed a functionalized graphon film," explains Ianfei .
He added that the newfunctional graphene could be as much as 50%. improve thermal conductivity. Moreover, the use of the properties of graphene nanomaterials results in an extremely high thermal conductivity coefficient on a relatively small surface area.
Used in future equipment
Huawei is optimistic about the future of graphene use, because this technology solution is relatively cheap and environmentally friendly. It is also important that current technology makes it easy to create a functional graph, so it can already be made for mass use.
As Ianfei said, the company has invested heavily in the development of this material before filing a patent. She has worked with many producers in the field of development and processing of graphene for obtaining thermal film certificates. All this allows us to assume that Huawei's protected technology in the near future will have a wide range of applications in different areas. The first examples of this have already been presented in London in October this year.
"By overcoming various obstacles and difficulties in using our production, our company has successfully achieved its goal and offered to the market the leading generation of" Mate 20 Ks ", crowning the launch of mass production of graphic film," the company spokeswoman said.
This device uses innovative cooling technology, which consists of a thin film of graphene film and cooling systems. This tandem guarantees that the device will maintain a low operating temperature under high loads, such as playing games or watching movies.
Functionalized graphic film used by Huawei Mate 20 Ks phones reduces the temperature of Kirin 980 chips, cameras and other heaters at about 1-2 degrees Celsius. This is sufficient to prevent overheating of the device. The company also plans to install a patented solution on all future devices.
