Description

technical field [0001] The present application relates to the technical field of heat storage equipment, in particular to a phase change heat storage device based on solar energy. Background technique [0002] Energy is an important material basis for the survival and development of human society, and is related to national economy and people's livelihood and national strategic competitiveness. my country has relatively abundant solar energy resources, which can make full use of the energy conversion of solar energy and promote the sustainable development of clean energy. However, for a long time, most of the heat storage devices involved in solar-to-thermal conversion only perform primary heat storage through water storage tanks, which generally have disadvantages such as small heat storage, low heat exchange rate, intermittent operation, and poor stability. Therefore, how to effectively utilize the energy of solar thermal conversion in multiple stages has become an urgent...
