▎ 摘　　要

NOVELTY - The heat management device has multiple battery monomers (1) that are provided to form a battery pack. A graphene film (2) is provided in contact with the battery monomer (1). An automatic heat insulating grid (3) comprises a radiating grid and heat radiating contact terminal. The graphene film is connected with the heat radiating contact terminal. A gap is provided between the heat radiating contact terminal and radiating grid. The radiating grid is provided in contact with the heat radiating contact terminal, when the heat radiating contact terminal is heated and expanded. USE - Heat management device for graphene battery. ADVANTAGE - The low temperature preservation of the battery pack and reduced temperature difference effect are achieved by the improved heat management device. The increased adaptability of the heat management device for the graphene battery is achieved by the improved heat management device. DESCRIPTION OF DRAWING(S) - The drawing shows a structural view of the heat management device. Battery monomer (1) Graphene film (2) Automatic heat insulating grid (3)
