It broke through the heat dissipation bottleneck of high-power chips for 5G products and passed tests by companies such as Huawei and ZTE. Moreover, this transformation project of military-civilian integration relying on the R & D team of Harbin Institute of Technology will also trigger a revolution in the field of heat dissipation materials.
The joint commissioning of the graphene composite powder production line is being carried out intensively. Liang Ye, Secretary of the Nangang District Party Committee, said: "To develop high-quality strategic emerging industries, Nangang District focuses on undertaking high-tech achievements of military-civilian integration and scientific research achievements of universities and colleges. "Graphene Military-civilian Integration Industry Demonstration Base".
New material with centimeter thickness
All kinds of electronic products on hand often become embarrassed to become "hot treasure" instantly. HECX Graphene New Materials Co., Ltd. deputy general manager Peng Qingyu told reporters that traditional heat-dissipating materials cannot effectively disperse the heat generated by the highly integrated electrical circuit and efficient heat dissipation, which has always been a difficult world-class problem. In the 5G era, communication equipment operates at high power, and the cooling function is more important. In 2017, Innovative Materials Co., Ltd. prepared high-performance graphene-based macroblock materials, and for the first time achieved effective grooming of high heat, filling international gaps.
"We breakthroughally made graphene into materials with a thickness of more than centimeters and integrated structure and function. This technology was originally used only in the aerospace field.
Relying on the R & D team of Harbin Institute of Technology, it will soon be used in civil fields such as communication base stations, electronic equipment, LED displays and lighting, and cooling of new energy vehicles, electronic circuits, and focused solar power generation. "Peng Qingyu introduced.
"At present, the first phase of the expansion and expansion of the special factory building of the heat sink project and the first phase of the graphene composite powder production line have been completed and commissioned. Joint commissioning is underway. Graphene composite powder preforming production lines, graphene heat dissipation materials The final molding production line, graphene heat dissipation material special processing production line and graphene heat dissipation material heterogeneous connection production line have completed the design, equipment selection and non-standard ordering, and are preparing for equipment bidding. "Peng Qingyu said that the entire project is expected to be completed by the end of this year The equipment is installed and put into trial production, and mass production is planned for the first half of next year.
Leading international project landing and transformation received help from multiple parties
Peng Qingyu told reporters that the global demand for heat-dissipating materials is about 200 billion U.S. dollars. At present, the demand for heat-dissipating materials in China's electronics industry is 30 to 40 billion yuan a year, and the market space in the future is considerable.
The total investment of the high-performance graphene composite heat sink project is 100 million yuan. As of the end of 2018, a total investment of 80 million yuan has been completed. Annual production of high heat flux graphene-based heat sink products is 30 million, with an annual output value of 400 to 600 million.
