The difficulty in solving the above problems and defects is:
how to select a reasonable structure to ensure the heat collection efficiency and organically combine the micro heat pipe technology, which phase change heat storage material is selected as a heat storage material and is combined with a heat collection and release structure, and which mode is adopted to enhance heat transfer and increase heat release.
