NOVELTY - A solar heat-storage heat-collector device consists of glass vacuum pipes, a heat transmission sleeve, a heat conductive material, an elastic corrugated rib plate, a thermal insulation plug, and a light collecting plate. The heat conductive material comprises (in vol.%) solid-solid phase-change heat-storage material (50), graphite powder (20), and heat conductive oil (30). The solid-solid phase-change heat storage material is crosslinked high-strength polyethylene, layered perovskite ore, or polyalcohol.    USE - Solar heat-storage heat-collector device.    ADVANTAGE - The solar heat-storage heat-collector device is simple in structure, safe and reliable in operation, and high and stable in thermal efficiency, and saves cost and space. The device efficiently stores heat on sunny days and releases heat on cloudy days. The outlet air or vapor working medium temperature can be stabilized to a certain special temperature zone from 120-190 degrees C.    DETAILED DESCRIPTION - A solar heat-storage heat-collector device consists of glass vacuum pipes, a heat transmission sleeve, a heat conductive material, an elastic corrugated rib plate, a thermal insulation plug, and a light collecting plate. The glass vacuum pipes are equipped on the light collecting plate. The heat transmission sleeve is provided at the center of glass vacuum pipes. The elastic corrugated rib plate is provided among the heat transmission sleeve and the inner walls of the glass vacuum pipes. The heat conductive material is provided in the space among the heat transmission sleeve and the inner walls of the glass vacuum pipes. The thermal plug is sealed to the upper end portions of the glass vacuum pipes and the outer wall of the sleeve. The heat conductive material comprises (in vol.%) solid-solid phase-change heat-storage material (50), graphite powder (20), and heat conductive oil (30). The solid-solid phase-change heat storage material is crosslinked high-strength polyethylene, layered perovskite ore, or polyalcohol.
