摘要:
为有效缓解湿热环境下带电作业人员所面临的热应激问题，保障生命安全与健康，提出基于CLO 3D和3D打印技术结合的多层结构冷却单元，研制出1种新型相变冷却服，并通过实验进行验证。研究结果表明：在相变冷却服的作用下，35 ℃环境下的假人皮肤温度的上升坡度相对平缓，降温时间长达150 min，随着环境温度的升高降温时间逐渐减少；在不同环境湿度下也表现出类似的趋势，湿度在超过75%后降温时间显著减少；随着劳动强度的增加，相变冷却服的降温效果逐渐减弱，尤其是在高强度劳动条件下，皮肤温度的上升趋势更加明显；进一步提出在不同作业条件下建议的最大连续作业时间。研究结果可为高温环境下带电作业人员的个体防护策略提供理论支持与工程参考。
Abstract:
In order to effectively mitigate the thermal stress faced by live working personnel in hot-humid environments and ensure their safety and health,this study proposed a multi-layer cooling unit integrating CLO 3D and 3D printing technologies,developing a novel phase-change cooling garment experimentally validated.The results demonstrate that under the phase-change cooling garment’s action,the manikin’s skin temperature exhibited a relatively gradual rise at 35 ℃ with cooling duration extending up to 150 minutes,and cooling duration progressively diminished with increasing ambient temperature.Notably,similar degradation patterns emerged under humidity variations,where exceeding 75% relative humidity triggered significant cooling efficacy reduction.Furthermore,the thermal regulation capacity of the phase-change garment progressively diminished with elevated work intensity,particularly under high-intensity conditions where skin temperature manifested more pronounced upward trajectories.Critically,recommended maximum continuous working durations were further established for diverse operational scenarios.These findings provide theoretical support and engineering guidance for personal protective strategies of live working personnel in high-temperature environments.
