A mobile energy storage device using superconducting heat pipes and copper foam phase change materials

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 mobile energy storage device adopting a super heat-conducting tube and a foamed copper phase change material. Background technique [0002] The recovery rate of industrial waste heat and waste heat in traditional steel, chemical, electric power and other high-energy and high-emission industries is very low. For example, low-temperature waste heat such as diffuse steam waste heat, slag-washing water waste heat, flue gas waste heat, compressed air waste heat, etc. has not been developed Utilization, which leads to a large amount of energy being consumed every year, and a large amount of gas emissions. At the same time, waste heat and waste heat recovery are still less utilized in the commercial and civilian markets, and most waste heat utilization projects are still insufficient in economy and flexibility. [0003] Today, energy conservation has obviously become an important socia...
