[0002] At present, the heat storage materials used in solid electric thermal storage equipment are generally refractory materials such as magnesium oxide thermal storage bricks and high-alumina bricks. However, with the development of society and the improvement of technology, more and more heat storage materials are being used in solid electric thermal storage equipment. New heat storage materials with high specific heat, high thermal conductivity or high density, such as carbon bricks, magnesia iron bricks, and magnesia carbon bricks, have emerged. The brick body of the solid electric thermal storage equipment is made of single bricks arranged in the form of pressed seams. It is generally divided into a flat layer and a hole layer (or heating wire layer). The hole layer is formed by rotating a single brick to form a brick hole. The heating wire is placed in the hole. When the heating wire is energized, it generates heat and stores the electrical energy as heat energy in the solid thermal storage brick. When heat is needed, the gas in the fan circulation system is forced to pass through the brick hole for heat exchange. The brick hole is both an air passage and a channel for installing the heating wire. Therefore, the insulation of the brick air passage must be guaranteed. However, the insulation properties of these materials cannot meet the requirements when heated. Utility Model Content
