Gaming, virtual reality and movie lovers can make it easier to take a break. Huawei patented with Cambridge University this year with an innovative solution that solves the problem of overheating smart phones. Improving the graph, eliminating some of the unwanted side effects, the engineers promise that the soon-to-patented solution will be distributed to all company entities. By the way, the new cooling solution has already been applied to one of the flagships in the Mate 20 series, which saw the daylight in October this year.
To strive for excellence and offer customers the most advanced technology, manufacturers encourage continuous investment in the creation and development of innovation. Over the past decade, Huawei has invested more than 44 billion in research and development. Euro. Based on these studies, the company has developed a variety of solutions to solve problems with smart equipment.
According to Yanfei, chief of Huawei Baltic Consumer Group, one has long been seeking a solution to overcome the overheating of equipment. According to him, this problem has arisen as people's needs grow when the phone begins to use increasingly resource-intensive activities like gaming or virtual reality.
"Previously, the development of smartphone games did not require much capacity, but with the ability to play on the Internet with other people, the requirements of both game developers and phone manufacturers began to be more demanding. In addition, virtual and add-on platforms that require high graphics capabilities also speed up the world. Because the graphics features of smartphones often are limited, there is also a problem with the cooling of the equipment. But it is a solution, says Yanfei.
According to him, business engineers were noted with researchers from the University of Cambridge on the graph. With its excellent thermal properties, this carbon shape has become the basis for the development of a thermal film designed to increase thermal conductivity of the device. It was not so easy before patenting the above innovation.
The graph needs to be improved
The grave can best be described as a thin graphite layer or high-conductivity carbon nanomaterial. Some researchers call it "the king of modern materials". According to Yanfei, one does not have to wonder about that name because the graph spends four times more effective heat than any other alloy and ten times better than copper.
Although the graph, like nanomaterials, has excellent properties, the use also causes some problems. For example, its conductivity may cause short circuiting or side effects in contact with other materials. For this reason, the team of Huawei engineers led by Nobel Prize winner Konstantin Novoselov and the team of researchers at Cambridge University developed an improved or so-called functional graphon.
"Functionalized grafon has one or more active molecules embedded in its surface. This prevents various side effects with other materials while retaining excellent electrical and thermal conductivity. This is precisely what we have achieved when we have developed a functionalized graphon film," explains Yanfei.
He adds that the newly-functional graph can be as high as 50%. improve thermal conductivity. Furthermore, the use of the properties of the graph nanomaterials results in an extremely high thermal conductivity coefficient over a relatively small surface area.
Used in future equipment
Huawei is optimistic about the future of graphing, as this technology solution is relatively cheap and environmentally friendly. It is also important that the current technology makes it easy to create a functionalized graphon, so it can already be manufactured for mass use.
As Yanfei says, the company has invested heavily in the development of this material before submitting a patent. She worked with many manufacturers in the development and processing of the graph to get a thermal film certificate. All of this allows us to assume that Huawei's proprietary technology in the near future will have a wide range of applications in different areas. And the first examples of this have already been presented in London in October.
"By overcoming the various barriers and difficulties in using our production, our company has successfully achieved its goal and has offered the market a flagship of Mate 20 X, breaking the launch of mass production of graph film," says a company spokesman.
This unit uses an innovative cooling technology, consisting of the thin film of graph film and coolant system. This tandem ensures that the device maintains a low operating temperature under heavy loads, such as playing games or watching movies.
The functionalized graphon film used by Huawei Mate 20 X phones reduces the temperature of the Kirin 980 chip, the camera and other radiators to about 1-2 degrees Celsius. This is enough to prevent the device from overheating. The company also plans for a patented solution to be installed on all future devices.
