On the evening of August 10th, in Lei Jun’s annual speech, the much-anticipated Mi MIX 4 mobile phone was officially released. Quantitative integrated precision ceramics, UWB one-finger connection, 120W wired fast charging and other new technologies, there is also a black technology that attracts special attention to electronic enthusiasts.
In the 5G era, thermal management has always been one of the most interesting issues for electronic products. Xiaomi, which is known for its black technology, did indeed live up to expectations and relaunched the black heat dissipation technology-the graphene "ice-sealed" heat dissipation system in this new work.
Lei Jun said in his speech that in order to achieve an excellent balance between high performance and temperature control, Xiaomi’s graphene "ice-sealed" heat dissipation system is the industry’s first 3D graphene Vapor Chamber: VC, with a thickness of 280μm and an area of up to 1232 mm2, covering the core heating area of the motherboard. The total heat dissipation area is as high as 11588 mm2, which greatly improves the heat dissipation efficiency.
It is understood that the graphene Vapor Chamber: VC is designed by special processing of graphene thermal conductive film. It mainly has: heat dissipation performance is equivalent to Vapor Chamber: VC, and the weight is only half of Vapor Chamber: VC. It is flexible and processable. High performance, lower cost than Vapor Chamber: VC and other advantages.
On May 27 this year, Nubia officially launched the Tencent Red Magic game phone 6R, which also uses the graphene heat dissipation film produced by GDMR Electronic Materials Technology Group. It is composed of olefin + VC liquid cooling + thermal conductive gel + superconducting copper foil + metal middle frame.
Among them, the graphene film, as a crucial line of defense for heat dissipation, can quickly dissipate the heat generated by the mobile phone, effectively reduce the temperature of the Red Magic 6R core CPU, and solve the problem of high-performance smartphones that have long been stuck and dropped frames during the game. , Fever and other heat dissipation pain points.
Public information shows that GDMR was established in 2011 by Dr. Cai, an industry leader who has been engaged in graphene research for 15 years. It is also the first company in China to achieve mass production of graphene thermal film across the entire chain of graphene oxide.
GDMR has a first-class scientific research team, which is composed of many national and provincial high-level talents, as well as more than 20 domestic and foreign doctors and masters. They have a deep understanding of the intrinsic properties of a variety of two-dimensional materials including graphene, are familiar with a variety of graphene preparation technologies, have obtained more than 30 graphene-related international and domestic patents, and have won three world-wide graphene fields.
In response to the increasingly severe heat dissipation problems of electronic products, in May 2019, GDMR invested in the establishment of YNMR Electronic Materials Technology Co., Ltd., which specializes in R&D, production and sales of graphene materials and high-performance graphene thermal film for solving the heat dissipation problems of 5G applications. It is the first company in China to complete the entire industrial chain from graphene raw material production to thermal film preparation.
Up to now, the total investment in the construction of the GDMR graphene thermal film project has exceeded 320 million yuan, and the entire process of the production line with an annual output of 1.6 million square meters of high-performance graphene thermal film has been opened up, and it is planned to reach an annual output of 2.2 million square meters of graphene thermal conductivity by the end of 2021. The scale of membrane production capacity.
At present, GDMR's graphene thermal film products have also been verified by many international mainstream manufacturers, and have achieved batch delivery for many applications.
GDMR focuses on the graphene research and development matrix, and has carried out application research and development and industrialization in the four major directions of thermal interface materials, new energy, advanced composite materials, and biological health. Committed to building an industrial chain cluster with application companies as the mainstay, and gradually applying graphene products to the fields of electronics, new energy, environmental protection, medical care, and military industry.
GDMR has confirmed to participate in the Fifth International New Materials, New Processes and Colors (CMF) Exhibition, which will display chemical graphene oxide, mechanically peeled graphene powder, CVD copper-based graphene film, graphene thermal conductive film, and graphene thermal conductivity Silicone grease, graphene heat dissipation coating, graphene foam, graphene lithium battery conductive agent, graphene-coated modified lithium ion electrode material, graphene-based lithium ion battery, graphene antistatic polymer composite material, graphene thermal conductivity Polymer composite materials, graphene-enhanced polymer composite materials, graphene TEM metal carrier network (special use for biological testing) and other products.
