Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of energy storage, and relates to a novel mobile energy storage device using superconducting heat pipes and foamed copper phase-change materials. Background technique [0002] The recycling rate of industrial waste heat and waste heat in traditional iron and steel, chemical industry, electric power and other industries with high energy consumption and high emissions is very low, such as low-temperature waste heat such as scattered steam waste heat, slag flushing water waste heat, flue gas waste heat, compressed air waste heat, etc. utilization, which results in a large amount of energy being consumed each year, while generating a large amount of gas emissions. At the same time, waste heat recovery is still underutilized in commercial and residential markets, and most waste heat utilization projects are still insufficient in economy and flexibility. [0003] Today, saving energy has clearly become an importa...
