NOVELTY - The utility model refers to a wall component field, especially a energy transfer element, solving the problem that the wall material is thick, in external ambient heat transfer cannot control technical problem, this utility model comprises exposing the outer side contact in graphene in environment, a middle insulating layer and exposed out of the side contacting the outer graphene in external environment, said three are arranged in sandwich-like combination, between the graphene layer and the graphene layer in the heat-transmitting connection mechanism capable of opening and closing is set. The utility model has light, sound and heat insulating, waterproof, flame retarding, and autonomous control in the outer environment of heat transfer.
