The heat storage and exchange body 1 is made of solid heat storage materials, phase change materials or liquid heat storage materials, a metal shell can be wrapped outside the heat storage and exchange body 1, and the heat storage materials and the metal shell jointly form the heat storage and exchange body 1. The heat storage and exchange body 1 can realize the function of heat storage. For example, the heat storage and exchange body 1 can be made of ceramic or high-temperature concrete. The shell 2 is made of heat-insulating material, can better store the stored heat of the whole structure, and can be modified perlite and calcium silicate. In specific implementation, a metal shell can be additionally arranged outside the shell 2 according to actual needs.
