▎ 摘　　要

NOVELTY - The graphene heat pipe has a tube casing (3). The left end of the tube casing is provided with an evaporation end cover (1), and the right end is provided with a heat dissipation end cover (5). The middle portion of the heat dissipation end cover is provided with a filling port, and the middle portion of the tube casing is provided with a liquid wick (2) and a hollow portion (4). The wick is composed of graphene pore-like structures with different gradient apertures. USE - Graphene heat pipe. ADVANTAGE - The heat pipe has good heat transfer performance and prolongs life. The olefin and carbon nanotube slurry can be baked at 70-100 degrees C without high temperature sintering, which can speed up production efficiency and reduce energy consumption. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene heat pipe. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the graphene heat pipe.
