▎ 摘　　要

NOVELTY - The pipe has an evaporation section shell embedded with a high thermal conductivity porous foam layer that is fixed with a heterogeneous nucleation vaporization core. The high heat-conducting porous foam layer is made of graphite and metal material. A network geometrical structure is irregularly connected with the heat-conducting porous foam layer. The high thermal conductivity porous foam layer is provided with a shortened condensing section. The heat-conducting porous foam layer is filled with working medium that is selected as graphene nano-fluid and surfactant. The surfactant is selected as sodium dodecylbenzene sulfonate. USE - Evaporation section embedded porous foam type graphene nanometer fluid gravity heat pipe. ADVANTAGE - The pipe has high heat exchanging efficiency, and promotes rapid air core phase changing effect and improves heat transfer resistance. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of an evaporation section embedded porous foam type graphene nanometer fluid gravity heat pipe.
