The heat-conducting rod 7 is a graphene plate, and a plurality of diamond-shaped air holes are arranged on one side of the heat sink 8. When the early warning device 3 is used, heat is generated, and the heat of the placement plate 2 passes through the heat-conducting rod 7 and the conveyor heat sink 8, and the heat dissipation operation is performed by relying on the diamond-shaped air holes on the heat sink 8 and natural wind. The heat-conducting rod 7 is made of a graphene plate. Graphene has very good thermal conductivity. The thermal conductivity of pure defect-free single-layer graphene is as high as 5300W / mK, which is the carbon material with the highest thermal conductivity so far, higher than single-walled carbon nanotubes (3500W / mK) and multi-walled carbon nanotubes (3000W / mK). When it is used as a carrier, the thermal conductivity can reach 600W / mK. In addition, the ballistic thermal conductivity of graphene can lower the lower limit of the ballistic thermal conductivity of carbon nanotubes per unit circumference and length.
