【摘要】 基于生物传热学原理,建立了气冷式降温服散热数学模型。利用Matlab对模型进行模拟,分析了不同工况条件下气冷服的散热特性。结果表明:气冷服通风温度、湿度越低,降温效果越好,且湿度的影响较为明显;服装热阻越小,其导热效果越好;随着环境温度的增大,衣服的内外层温度均增大,且内层温度增长速率要高于外层服装。分析结果为气冷式降温服设计提供参考。更多还原

【Abstract】 Based on the biological heat transfer,establish the heat transfer model for air-cooled suits。 Analyzed the cooling characteristics simulated the heat dissipation characteristic of cooled suits.The results shows:Air cooled uniform ventilation,the lower the temperature,humidity,the better of the air cooled uniform cooling effect,and the influence of humidity is more obvious;the smaller Clothing thermal resistance,the better thermal effect;With the increase of ambient temperature,the clothes inside and outside temperature were increased,and the inner temperature growth rate is higher than the outer garments.This paper provides a reference for subsequent research on the air cooling system.更多还原
