▎ 摘　　要

NOVELTY - A heat transfer fluid comprises an organic fluid, a phase change material, and graphene. USE - Heat transfer fluid used in energy storing systems and heat transfer system e.g. compressed air energy system (all claimed), concentrated solar power and wind turbines. ADVANTAGE - The heat transfer fluid has high thermal stability, and improved heat conductivity and viscosity characteristics. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) energy storing system, which contains the heat transfer fluid; and (2) heat energy exchange in heat transfer system, which involves contacting the heat transfer fluid having high capacity profile with a heat exchange surface to allow heat to be conducted through the organic fluid to the phase change material. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of heat fluid in the heat exchange system.
