摘　　要：针对蓄冷板内相变材料(PCM)的蓄冷过程建立模型,分析蓄冷板外壳材质、蓄冷板厚度和蓄冷环境温度对PCM蓄冷速度(完全固化时间)的影响。结果表明:当蓄冷板外壳材质由高密度聚乙烯更换为不锈钢后,PCM完全固化时间缩短11.6%;当蓄冷板厚度由25mm减小至20mm时,PCM完全固化时间缩短15.7%;当蓄冷板厚度由25mm减小至15mm时,PCM完全固化时间缩短36.8%;随着蓄冷环境温度的降低(247.15~237.15K),PCM完全固化时间缩短。The model of cold storage process of phase change material(PCM)in cold storage plate is established.The effects of shell material,thickness of cold storage plate and cold storage ambient temperature on PCM cold storage speed(complete solidification time)are analyzed.The results show that when the shell material of cold storage plate uses stainless steel instead of high density polyethylene(HDPE),the complete solidifica-tion time of PCM is reduced by 11.6%.As the thickness of cold storage plate is reduced from 25 mm to 20 mm,the complete solidification time of PCM is reduced by 15.7%;as the thickness of cold storage plate is reduced from 25 mm to 15 mm,the complete solidification time of PCM is reduced by 36.8%.With the decrease of the cold storage ambient temperature decreasing from 247.15 K to 237.15 K,the complete solidification time of PCM decreases.
