CZFX Graphene Technology Co., Ltd. announced on June 17 that Hubble, a subsidiary of Huawei, has newly invested in the company, with a 10% stake. CZFX is a high-tech enterprise with independent intellectual property rights, specializing in the development, production and sales of graphene thermal film.
Due to the substantial increase in power consumption of 5G mobile phones, new heat dissipation materials and three-dimensional heat dissipation designs are needed to fully improve the heat dissipation performance. Graphene has the advantages of good thermal conductivity and fast heat dissipation. It can be greatly matched with new materials such as heat pipes and VC with good thermal conductivity. Improve the cooling effect of 5G mobile phones. Major mobile phone manufacturers have adopted graphene thermal films. In 2020, Huawei adopted graphene thermal films in P40 series mobile phones; Xiaomi adopted graphene thermal films in Xiaomi 10 series and RedmiK30 Pro mobile phones.
The soaking plate + graphite/graphene combination is expected to accelerate penetration as the 5G replacement wave advances. At the same time, the power consumption of 5G base stations is about 2 to 3 times higher than that of 4G base stations, bringing new business needs to the heat dissipation industry chain.
In addition, there are two high-end graphene thermal film manufacturers in China:
The graphene thermal film products of XC Graphene Technology Company, a subsidiary of SZDE Group, have been used in batches in mobile phone radiators and LED heat dissipation components. They have passed the approval of relevant downstream customers and signed a framework cooperation agreement.
ZGBA Group's subsidiary SZSR Graphene Technology Co., Ltd.'s graphene thermal film product technology is in a leading position. Graphene thermal film has also been supplied to Chinese brand mobile phone manufacturers.
