▎ 摘　　要

NOVELTY - The structure has a graphene-based composite substrate and a high thermal conductivity copper block (5). The graphene-based composite substrate is perforated longitudinally. A position of a hole is at a contact point of the graphene-based composite substrate and a heat source. The high thermal conductivity copper block is embedded in the pores of the graphene-based composite substrate. USE - Thermal structure embedded with Copper in graphite alkenyl composite material substrate. ADVANTAGE - The heat of the heat source is conducted well in the out-of-plane direction of the high-oriented graphene material, and the high-oriented material with excellent in-plane thermal conductivity is combined to rapidly diffuse heat. Hence, the problem of poor longitudinal thermal conductivity is solved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of thermal structure embedded with Copper in graphite alkenyl composite material substrate. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the thermal structure of high oriented graphene and copper block. Heat-conducting copper block (5) Perforated graphene plate (7)
