DETAILED DESCRIPTION - Multi-layer graphene ring layer of three-dimensional adjustable heat invisible cloak comprises substrate layer, insulating spacer layer, graphene ring layer covered on the surface of ring layer, internal supporting shell, control unit and energy supply unit. The surface covering ring layer comprises graphene ring layer. Each two graphene ring layer are arranged between insulating spacer layer isolation. The internal supporting shell is in multi-layer graphene inner ring layer. The multi-layer graphene is used for bearing the ring layer. The hidden target is placed in the inner cavity of internal supporting shell. The internal supporting shell layer is in contact with graphene ring. The internal supporting shell corresponding to each graphene ring layer is drilled with small hole. The small hole is internally provided with wire. One end of wire is connected in graphene ring layer. The other end sequentially passes through the control unit and energy supply unit is grounded. The temperature field and isotherm is restored to original distribution.
