DETAILED DESCRIPTION

[0015] Refer to Figs. 1-2 The embodiment of the utility model is further explained.

[0016] An intelligent terminal based on graphene composite material high thermal conductivity, including shell 1, core plate 2, main plate 3 and superconducting composite material heat dissipation module 4, CPU is installed on the core plate 2, and the core plate 2 is installed on the main plate 3 to form circuit board 5, the circuit board 5 is installed on the shell 1, the shell 1 includes heat dissipation space 7, the superconducting composite material heat dissipation module 4 is placed in heat dissipation space 7, the superconducting composite material heat dissipation module 4 includes heat conduction plate 8 and heat dissipation plate member 9, heat conduction plate 8 is made of graphene material, heat dissipation plate member 9 is made of aluminum base material, heat conduction plate 8 is installed on the inner wall of shell 1, the bottom of heat dissipation plate member 9 is installed on heat conduction plate 8, the top of heat dissipation plate member 9 is installed on main plate 3 and in contact with core plate 2, and the surface of heat dissipation plate member 9 is coated with graphene composite material.

[0017] Working principle: when the heat of the core board 2 is dissipated through the heat dissipation plate 9, since the heat dissipation plate 9 is made of aluminum material with low thermal conductivity, and the surface of the heat dissipation plate 9 is coated with graphene composite material with high thermal conductivity, the thermal conductivity of the heat dissipation plate 9 is greatly improved, the speed of heat transfer from the core board 2 to the heat dissipation plate 9 is accelerated, so that the heat dissipation plate 9 can quickly dissipate the heat on the core board 2 to the surrounding environment, and the temperature of the core board 2 is quickly reduced. The heat conducted to the heat dissipation plate 9 by the core board 2 is conducted to the heat spreading plate 8 at the bottom of the heat dissipation plate 9, so that the local heat conducted by the heat dissipation plate 9 is dispersed to the surface of the entire heat spreading plate 8, thereby further reducing the temperature of the core board 2 and achieving the purpose of cooling. The heat spreading plate 8 is made of graphene material, so that the local heat conducted by the heat dissipation plate 9 is quickly dispersed to the surface of the entire heat spreading plate 8, thereby further accelerating the cooling speed of the core board 2, and finally achieving the purpose of quickly conducting the heat of the terminal core board 2 to the outside and quickly cooling and dissipating heat, thereby reducing the failure rate of the intelligent terminal.

[0018] The heat dissipation plate 9 comprises a heat conduction plate 91, a heat conduction top plate 92, a heat conduction bottom plate 93 and a plurality of heat dissipation teeth 94. The heat conduction top plate 92 and the heat conduction bottom plate 93 are respectively installed on the top and bottom of the heat conduction plate 91. The plurality of heat dissipation teeth 94 are arranged between the heat conduction top plate 92 and the heat conduction bottom plate 93 and symmetrically distributed on both sides of the heat conduction plate 91. The heat conduction top plate 92 is installed on the main board 3, and the main board 3 comprises a heat dissipation port 10 connected with the core board 2. The convex plate on the core board 2 passes through the heat dissipation port 10 and contacts with the heat conduction top plate 92. The heat conduction bottom plate 93 is installed on the heat spreading plate 8.

[0019] The plurality of heat dissipation teeth 94 increase the heat dissipation area of the heat dissipation plate 9, which is beneficial to quickly conducting the heat of the core board 2 to the surrounding air and improving the heat dissipation effect. The heat conduction top plate 92 and the heat conduction bottom plate 93 increase the contact area of the heat conduction plate 91 with the core board 2 and the heat spreading plate 8, which is beneficial to quickly conducting the heat on the core board 2 to the heat dissipation plate 9 and the heat spreading plate 8 for heat dissipation and improving the heat dissipation effect. The heat dissipation port 10 enables the core board 2 to be installed on the main board 3 while contacting with the heat conduction top plate 92, which is beneficial to directly conducting the heat on the core board 2 to the heat dissipation plate 9 through the heat conduction top plate 92 and quickly conducting the heat on the core board 2.
