▎ 摘　　要

NOVELTY - The graphene nano-refrigerant pulsating heat pipe comprises a capillary copper tube bent. The two ends of the capillary copper tube bent communicate with each other to form a closed-loop circuit. The graphene nanoparticles and refrigerant is mixed under the action of surfactant to form graphene nanofluid. The volume filling rate of the phase change heat transfer working medium is less than or equal to eighty percent. The graphene nanoparticles are multi-layer graphene with a thickness less than 8 nano-meter. USE - Graphene nano-refrigerant pulsating heat pipe. ADVANTAGE - Solve the problem of low thermal conductivity of the heat transfer medium. Significantly improve the thermal conductivity of the heat transfer medium. Improves the heat transfer efficiency. Reduce the start-up time of the heat pipe. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic structural diagram of a graphene nano-refrigerant pulsating heat pipe.
