Abstract

The present invention relates to the technical field of thermal insulation boards, and discloses an assembled lightweight composite thermal insulation energy-saving board, which includes a cladding panel, and further includes an outer thermal insulation board and an inner thermal insulation board fixedly connected inside the cladding panel, a soundproofing board fixedly connected between the outer thermal insulation board and the inner thermal insulation board, and two outer silicone sheets fixedly connected to the left and right sides of the cladding panel respectively. Phase change materials are provided inside both the aluminum bars and the outer silicone sheets, and the aluminum bars and the aluminum sheets equalize the internal temperature of the cladding panel. The outer thermal insulation board and the inner thermal insulation board form a double-layer thermal insulation structure, while forming a basic thermal resistance barrier with the soundproofing board to slow down the heat loss. The aluminum sheets and the aluminum bars form a criss-crossing heat conduction network, and the phase change materials inside the aluminum bars and the outer silicone sheets can be used to keep good thermal insulation and energy-saving effects during solid-liquid transformation, thereby significantly reducing the energy consumption of the building.
