Abstract
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.
