采用芯材为石蜡、壁材为密胺树脂的微胶囊相变材料制备制冷背心样衣，与隔绝式防护服配套使用．在室温36℃、相对湿度60％的条件下，测定穿着未配有和配有制冷背心的隔绝式防护服时人体胸温、背温、手温、腿温和肛温等的变化；结合人体产热、散热经验式与伍德科克人体散热理论建立模型，探讨人体穿着配有制冷背心的隔绝式防护服后人体平均体温随穿着时间的变化．发现穿着配有制冷背心的隔绝式防护服后，人体胸温、背温、手温、腿温和肛温明显下降．建模计算分析表明，穿着配有制冷背心的隔绝式防护服后，人体平均体温随穿着时间的变化关系的计算值与实验测试结果吻合．

With melamine resin as the shell and with encapsulated phase change material and was applied paraffin as the core, a cooling vest was prepared from micro- to the impermeable protective clothing. Then, the effects of wearing time on the chest temperature, the back temperature, the hand and leg temperatures, and the rectal temperature of the volunteer wearers of the protective clothing with and without the cooling vest were measured at a room temperature of 36 ℃ and with a relative humidity of 60%. Moreover, according to the empirical formula of heat production and dissipation in the human body and the Woodcock equation, the relationship between the average body temperature and the wearing time was investigated. The results show that the cooling vest greatly reduces the temperatures of such body parts as the chest, the back, the hand, the leg and the rectal, and that the modeling calculation results of the variations in the average body temperature with the wearing time accord well with the experimental ones.
