A mobile energy storage device using copper foam phase change material

Abstract

The invention discloses a novel movable energy accumulation device using foamy copper phase change materials. The novel movable energy accumulation device comprises multiple single body phase change energy accumulators which are connected in parallel. Each single body phase change accumulator comprises a sealed cylindrical shell. Each shell comprises an outer-layer sleeve, an inner-layer metal sleeve and an interlayer, wherein a sealing opening in the upper end of a superconduction heat pipe is inserted in the upper portion of the interior of the shell, and an opening in the lower end of the superconduction heat pipe is exposed out of the shell and is connected with a waste heat source; the part between the inner-layer sleeve and the superconduction heat pipe is filled with the foamy copper phase change materials; and a spiral pipeline is further arranged in the shell to pass between the phase change materials, and the shell interlayer and the spiral pipeline in the shell are cold water channels. The multiple single body phase change energy accumulators are erected side by side, water inlets in the upper ends of the multiple single body phase change energy accumulators are connected with a water inlet pipe, and water outlets in the lower ends of the multiple single body phase change energy accumulators are connected with a water outlet pipe. According to the novel movable energy accumulation device, the superconduction heat pipe is used for recycling waste heat, heat transmission is fast, and the heat transmission efficiency is high; the heat conduction coefficient of the phase change material is increased through foamy copper, and the heat accumulating and releasing rate is increased.

Description

technical field [0001] The invention belongs to the technical field of energy storage, and relates to a mobile energy storage device using 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 important social awareness in today's world....
