Description

technical field [0001] The present invention relates to a thermal shock-resistant solid heat storage device. Background technique [0002] The use of solid energy storage technology for electric heat storage during the off-peak period, and the application of electric heat storage to building heating, is of great value to the power peak regulation of the power grid and the reduction of user heating operation costs. [0003] At present, the solid heat storage components used in the solid heat storage electric heating devices on the market are all made of magnesium oxide as the main material, making full use of the characteristics of high temperature resistance, large specific heat capacity and excellent thermal conductivity of magnesium oxide. However, magnesium oxide also has the problems of large thermal expansion coefficient and poor thermal shock resistance, which makes it easy to generate excessive thermal stress inside the thermal storage material during high and low tem...
