摘要

对11种相变材料(PCMs)在热应激条件下的冷却性能进行了评价。研究了包装材料和分割的影响。在热板上研究了不同类型PCM(水基和油基PCM，冷却凝胶，无机盐)或不同包装(铝，TPU, TPU +氯丁橡胶)的样品包装。确定制冷量、持续时间和功率。其次，一个六边形隔间的PCM包与一个类似内容的未分割版本进行比较。随着熔化温度的升高，冷却功率降低，冷却时间延长。水基pcm的冷却能力比其他pcm高2倍以上，但寿命相对较短。柔性凝胶和盐在冷却能力方面没有表现出相变平台，从而影响了它们的冷却潜力。使用TPU或铝包装是无关紧要的。添加氯丁橡胶大大延长了冷却时间，同时降低了功率。分割有实际的好处，但大大降低了接触面积，因此冷却功率。

Evaluation of Phase Change Materials for Personal Cooling Applications

Eleven phase change materials (PCMs) for cooling humans in heat-stressed conditions were evaluated for their cooling characteristics. Effects of packaging material and segmentation were also investigated. Sample packs with a different type PCM (water- and oil-based PCMs, cooling gels, inorganic salts) or different packaging (aluminum, TPU, TPU + neoprene) were investigated on a hotplate. Cooling capacity, duration, and power were determined. Secondly, a PCM pack with hexagon compartments was compared to an unsegmented version with similar content. Cooling power decreased whereas cooling duration increased with increasing melting temperature. The water-based PCMs showed a >2x higher cooling power than other PCMs, but were relatively short-lived. The flexible gels and salts did not demonstrate a phase change plateau in cooling power, compromising their cooling potential. Using a TPU or aluminum packaging was indifferent. Adding neoprene considerably extended cooling duration, while decreasing power. Segmentation has practical benefits, but substantially lowered contact area and therefore cooling power.
