Solar phase change heat storage and thermoelectric power generation device

Abstract

The invention belongs to the technical field of solar photo-thermal power generation, and in particular provides a solar phase change heat storage-thermoelectric power generation device. The inventionaims to solve the problem that the power generation efficiency of the existing thermoelectric power generation device is easily affected by the solar radiation intensity. The thermoelectric power generation device of the invention comprises a thermoelectric power generation assembly and a heat storage assembly connected with the thermoelectric power generation assembly. The thermoelectric power generation assembly can convert solar energy into electric energy and output the electric energy. The heat storage assembly comprises a shell and a phase change heat storage element accommodated in theshell. The phase change heat storage element can absorb sun radiation and convert solar energy into thermal energy for storage. When the intensity of solar radiation changes, the heat storage assembly can exchange heat with the thermoelectric power generation assembly so as to stabilize the working temperature of the thermoelectric power generation assembly, ensure that the thermoelectric power generation assembly can output electric energy stable and stabilize the power generation efficiency of the thermoelectric power generation assembly.
