Heat collector phase change energy storage heat supply system

The utility model relates to a heat collector phase change energy storage heat supply system, which relates to the field of heat supply, and comprises a solar heat collection loop, a light gathering plate, an adjuster, a heat preservation tank and a heat absorption pipe, the solar heat collection loop comprises a heat collection pipe, connecting pipes and a heating pipe, and two ends of the heating pipe are respectively connected and communicated with two ends of the heat collection pipe through the two connecting pipes. The light gathering plate is rotatably located on the outer side of the heat collecting pipe, the adjuster is in transmission connection with the light gathering plate, the heat preservation tank is filled with phase-change materials, the heating pipe is partially or completely located in the phase-change materials, and the heat absorbing pipe is partially or completely located in the phase-change materials. The device has the advantages that the phase-change material is high in heat storage
