A liquid-cooled garment with active cooling function can make up for deficiency of the human thermoregulatory system and passive thermal insulation of the firefighting protective suit. Fabrics treated at different inlet temperatures and pipeline intervals were applied in multilayered liquid-cooled fabric assemblies (LCFAs). The heat absorbed by the skin and the second-degree burn time were evaluated by the stored energy test under low heat radiation. Results indicated that the thermal protective performance of the LCFAs was significantly improved, with the second-degree burn time increasing more than 50% on average. There was a strong negative correlation between the thermal protective performance and cooling effect under different pipeline intervals, while the negative correlation was weak for different inlet temperatures. The results gained from this study may provide valuable insight for design of the inlet temperature and pipeline interval of a liquid-cooled system in the firefighting protective suit.
具有主动冷却功能的液冷服装可以弥补人体热调节系统和消防服被动隔热的不足。不同入口温度和管道间隔处理的织物应用于多层液冷织物组件 (LCFAs) 中。在低热辐射下通过储能试验评估皮肤吸收的热量和二度烧伤时间。结果表明，LCFAs 的热防护性能显著提高，平均二度烧伤时间增加了 50%以上。在不同的管道间隔下，热防护性能和冷却效果之间存在很强的负相关关系，而在不同的入口温度下，负相关关系较弱。本研究的结果可为消防服液冷系统的入口温度和管道间隔设计提供有价值的见解。
