摘　　要：为优化电加热服的设计,建立皮肤、衣下空气层与加热型织物的组合体,探索其对加热型织物系统传热性能的具体影响。选用6种不同的织物,并通过在测试板与织物之间放置不同厚度的分隔板来模拟衣下空气层,分析加热装置关闭与打开时加热型织物系统的热阻和加热装置提供给测试板的加热功率的变化,评价织物系统的热量传递。结果表明:不论加热装置是否开启,加热型织物系统的热阻都随空气层厚度的增大而增加;加热装置打开时织物性能对织物系统热阻的影响增强;加热装置放置位置越靠近皮肤,加热效率越高。In low temperature environment, it is necessary to wear cold protective clothing to maintain thermal comfort of human body, so lightweight and thermostatically controlled electric heating clothing is widely concerned. The electric heating clothes on the market lack strict design ideas, which may lead to skin burns or lack of warmth, resulting in waste of battery energy, and making it difficult for the electric heating clothes to heat effectively for a long time. Through literature review, it is found that the research on heat transfer performance of the fabric system without internal heat source is relatively perfect, and the main influencing factors are fabric properties and undergarment air layer;for electric heating clothing with internal heat source, there is a lack of systematic research and quantitative analysis on the influence of fabric properties and air layer on the heat transfer performance of electric heating clothing.In order to optimize the design of electric heating clothing, the influence of fabric properties and air layer on the heat transfer performance of the fabric system was studied. Six kinds of fabrics commonly used for cold protective clothing in low temperature environment were selected, and there were differences in terms of thickness, thermal resistance and air permeability. The combination of skin, air layer and heated fabric was established, and the air layer was simulated by placing spacer between the test panel and the fabric. The thicknesses of the six kinds of air layers were 0, 3, 6, 9, 12 and 15 mm, respectively. The thermal resistance of the heated fabric system and the change of the heating power provided by the heating device to the test plate were tested and analyzed when the heating device was turned off and on using the thermal plate and the climate chamber, and the heat transfer of the fabric system was evaluated. We systematically studied the specific effects of different fabric properties and air layer thicknesses on the heat transfer performance of the fabric system wh
