▎ 摘　　要

NOVELTY - Solar phase change heat collector comprises a heat collecting box, a solar heat collecting glass pipe and a superconducting liquid circulating pipe. The solar heat collecting glass pipe is provided with multiple of and connected with the heat collecting box. The solar glass pipe and the heat collecting box is composite nano metal particle phase change emulsion. The superconducting liquid circulating pipe spiral disc is set in the heat collecting box and the two ends are respectively the super-liquid outlet end and the superconducting liquid inlet end. USE - Solar phase-change heat collector for a solar phase change heating system (claimed). ADVANTAGE - The collector utilizes specific composite nano metal particle phase change emulsion to obtain composite phase change energy storage material with high heat conductivity coefficient and latent heat value and low viscosity so as to successfully finish convection heat exchange process in a vacuum tube during exothermic process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a solar phase change heating system with low energy consumption. DESCRIPTION OF DRAWING(S) - The drawing shows a structural diagram of the solar phase-change heat collector
