Gaming, virtual reality and movie buffs can ease the break. Huawei has patented Cambridge University this year with an innovative solution that will solve the problem of overheating smart phones. Improvement of graphene, thus eliminating some undesirable side effects, engineers promise that the soon-to-be-patented solution will be used on all company devices. By the way, the new cooling solution is already suitable for one of the leading Mate 20 series ships that saw the daylight in October this year.
In order to achieve excellence and to offer customers the most advanced technologies, manufacturers are encouraging continuous investment in innovation creation and development. 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, head of the Huawei Baltic Consumer Group, a long-term solution was sought to overcome the overheating of equipment. According to him, this problem has arisen as people's needs grow when the phone starts using more and more resource-intensive activities such as gaming or virtual reality.
"Formerly the development of smartphone games did not require a lot of power, but with the ability to play on the Internet with other people, the demand for gaming developers and phone manufacturers began to become more demanding. Moreover, virtual and additional reality platforms that require high graphics capacity also get As the graphics capabilities of smartphones are often limited, there is also a problem with the cooling of the machine, but this is a solution, "says Yanfei.
According to him, engineers at the University of Cambridge paid attention to graffiti. Thanks to its excellent thermal properties, this carbon form has become the basis for heat-shrinking, which is intended to increase the thermal conductivity of the device. Indeed, it was not so easy before patenting the above innovation.
Graffen had to be improved
Graffen can best be described as a thin graphite layer or carbon nanomaterial with high thermal conductivity. Some scientists call it the "king of modern materials". According to Yanfei, you do not have to wonder about that name because the dipper spends four times more efficient heat than any other alloy and ten times better than copper.
Although graphon, like nanomaterial, has outstanding properties, its use also creates certain problems. For example, its conductivity can cause short circuits or side effects when in contact with other materials. For this reason, the Huawei engineering team, led by the Nobel Prize winner Konstantin Novoselov and the team at the University of Cambridge, have developed an improved or so-called functional graph.
"The functional graphene has one or more active molecules that are immersed in its surface, which eliminates the various side effects of other materials while maintaining excellent electrical and thermal conductivity, which is exactly what we have been able to achieve when we have developed a functional grapheme film", explains Yanfei.
He adds that the value of a new functionalized grapha can reach 50%. improve thermal conductivity. In addition, the properties of graphite nanomaterials have a very high thermal conductivity coefficient on a relatively small surface area.
Used in future equipment
Huawei is optimistic about the future of the use of graphon, as this technology solution is relatively inexpensive and environmentally friendly. It is also important that the current technology facilitates the creation of a functioning graph, so it can be done massively.
As Yanfei says, the company has invested heavily in developing this material before submitting a patent. She worked with many manufacturers in the field of graphon development and processing to obtain a thermal film certificate. All this suggests that in the very near future, Huawei's proprietary technology will have a wide range of applications in a variety of areas. And the first examples from it were already presented in London this October.
"By overcoming the various obstacles and difficulties with our products, our company has successfully achieved its goal and has offered the market for the Mate 20 X Leading Card, which turns the mass production of graphic film," says a company spokeswoman.
This device uses innovative cooling technology, which consists of a graphite film and a thin film of the cooling system. This tandem guarantees that the device will maintain low operating temperatures in heavy loads, such as playing games or watching movies.
Functional graphene film used on the Huawei Mate 20 X phones reduces the Kirin 980 chip, the temperature of the camera and other heating elements by about 1-2 degrees Celsius. This is enough to prevent the device from overheating. The company also plans that a patented solution will be installed on all future devices.
