The invention discloses a novel movable type energy storage device using superconductive tubes and copper foam phase-change materials. The novel movable type energy storage device using the superconductive tubes and the copper foam phase-change materials comprises a plurality of parallel single phase-change heat accumulators, wherein each single phase-change heat accumulator comprises a closed cylindrical shell; each shell comprises an outer sleeve, an inner metal sleeve and an interlayer; the interlayer of each shell is a cold water channel; a spiral guide ring is arranged in the interlayer of each shell; a superconductive tube is arranged in each shell; the upper end of each superconductive tube is sealed and inserted in the upper part of the inside of the corresponding shell; the lower end of each superconductive tube is open, is exposed outside the corresponding shell and is connected with a waste heat source; a phase-change material which is used for filling holes of copper foam is used for filling between the corresponding inner sleeve and the corresponding superconductive tube; the single phase-change heat accumulators are erected side by side; a water inlet of the upper end of each single phase-change heat accumulator is connected with a water inlet tube through a water collecting square tube; and a water outlet of the lower end of each single phase-change heat accumulator is connected with a water outlet tube through a three-way tube. The novel movable type energy storage device recycles the waste heat by the superconductive tubes, and is quick in heat transmission and high in heat conduction efficiency; and by the copper foam, the heat conduction coefficient of the phase-change materials is improved by the copper foam, and heat storage rate and heat release rate are increased.
