摘要

摘要: 对填充有泡沫铜的固-液相变储热装置进行了试验研究.采用纯度为98%的正21烷(C₂₁H₄₄)作为相变材料(PCM),通过抽真空灌注的方法将其灌注到泡沫铜内部,封装并作绝热处理后作为试验件.在进行储热试验时,用嵌入了加热棒的铝制底座模拟被散热件对试验件加热,利用探针式和贴片式铂电阻(pt100)测量试验件温度并通过数据采集仪进行采集.整理绘制了在不同加热功率下的温度时间曲线,讨论和分析了此装置的热性能,结果表明泡沫铜作为填充材料能明显改善相变储能装置的传热性能和内部温度均匀性.

Abstract: The thermal performance of solid-liquid phase change thermal storage device which embedded with copper foam was investigated. The 98％ pure Heneicosane (C₂₁H₄₄) was used as the phase change material (PCM), and it was filled in the copper foam through a vacuuming procedure. The PCM and the copper foam were sealed and insulated to get the test vessel. An aluminum bed plate which embedded with heating rods was used to heat the test vessel, and the temperature of the vessel was measured by some plate-type and probe-type platinum-resistance thermocouples (pt100) and collected by a data acquisition unit. The temperature variation curves under various heating power were plotted and the results were discussed. Experimental results indicate that, the thermal conductivity and performance of the phase change thermal storage device is obviously improved while copper foam as a heat transfer enhancement.
