▎ 摘　　要

NOVELTY - A composite heat transfer component (1) comprises a plate (10) composed of a carbonaceous material composed of a composite containing graphene aggregates and graphite particles formed by depositing single-layer or multilayer graphene, and a cast metal component (20) that covers the surface of the plate. USE - Composite heat transfer component used for central processing unit, power module, aluminum automobile, light-emitting diode head lamps, and mobile phone base stations. ADVANTAGE - The composite heat transfer component has excellent heat conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of the composite heat transfer component, which involves arranging a plate made of a carbonaceous material composed of a composite of graphene aggregates and graphite particles formed by depositing single-layer or multi-layer graphene in a cavity of a mold, forming a cast metal component by supplying a molten or semi-melted metal into the cavity, and coating the surface of the plate with the cast metal component. DESCRIPTION OF DRAWING(S) - The drawing shows an explanatory view of the composite heat transfer component. Composite heat transfer component (1) Plate (10) Cast molding component (20)
