The invention relates to a heat superconducting phase change energy storage heat exchanger, and belongs to the field of new energy, energy saving and environment friendliness. The heat exchanger is used for storing and reutilization of multiple kinds of heat energy. A heat superconducting pipe comprises a heat absorbing fin set, a phase change material container and a cooling fin set; the cooling fin set is welded to the upper end of the heat superconducting pipe, the energy storage material container is placed in a heat preservation shell and welded to the middle of the heat superconducting pipe along a center hole, and a sealed space is formed by the energy storage material container and the heat superconducting pipe; the heat absorbing fin set is welded to the lower end of the heat superconducting pipe; a metal wire net or large-hole-diameter foam metal is arranged in a phase change material container cavity, an upper top cover and a lower top cover of the heat preservation shell are each provided with a filling pipe, and the filling pipes are used for filling in of phase change energy-storage materials and discharging and replacing of the energy-storage materials; the cooling end is set to be at the control temperature, fluctuation of the temperature of a heat source of a heating segment is not stable, and the temperature and energy output and input can be automatically balanced through the heat exchanger. When the temperature of the heating segment is too high, heat is rapidly stored in the phase change energy-storage material, and the overheat protection effect is provided for the cooling end; when the temperature of the heating segment is reduced or the heat supply is not sufficient, the phase change energy storage material outputs heat to the cooling end, the temperature and heat flow fluctuation is controlled within a certain range, and input and output changes are balanced.
