NOVELTY - The utility model belongs to new energy automobile battery pack heat insulation radiating technology field, claims a gas gel heat insulation radiating fin for new energy automobile battery pack. comprising a first heat insulating layer, a second heat insulating layer and a heat conducting layer; the first heat insulating layer, the second heat insulating layer and the heat conducting layer are rectangular and the length direction central axis of the three are in the same vertical plane; the second heat insulating layer is built in the first heat insulating layer; the heat conducting layer is adhered to the bottom surface of the first heat insulating layer; wherein the first heat insulation layer is aerogel sandwich material, the second heat insulation layer is aerogel felt, the heat conducting layer is copper foil, one or two of the composite sheet of graphene film. The utility model transversely can well isolate the battery at two sides; the heat is dissipable through the heat conducting layer at the bottom, avoiding the whole battery pack in the heat concentration state caused by one side temperature, affecting the safety performance; At the same time, the unique flexibility of the first heat insulation layer makes the battery pack have a certain buffer capacity when it is expanded by the outer boundary.
