Following the first application of graphene film in Huawei Mate20X, Huawei's first domestic 5G tablet Huawei MatePad Pro 5G recently released, equipped with ultra-thick 3D graphene cooling technology. This technology uses graphene as a raw material and uses highly oriented thermal conductive films stacked by multiple layers of graphene. It has the characteristics of good mechanical properties, high thermal conductivity, light weight, thin materials and good flexibility. With the wave of 5G mobile phone replacement and the peak of base station construction, graphene is expected to rapidly expand its application in heat dissipation solutions for electronic equipment due to its extremely high thermal conductivity and thermal radiation coefficient.
