摘　　要：真空绝热板(VIP)具有10倍于传统绝热材料的优异绝热性能。对VIP有效导热系数进行了分析,表明影响VIP绝热性能主要是固体导热和辐射传热,而气体导热和对流换热可忽略不计。影响VIP整体绝热性能的因素主要有温度、气体压力、含湿率、芯材密度及芯材颗粒度等参数。VIP has excellent thermal insulation performance, the thermal resistance of which is ten times higher than conventional insulation materials. Through analysis on effective thermal conductivity of VIP, it is indicated that the main influence items on VIP thermal performance are solid thermal conduct and radiation heat transfer, while the influence of gas thermal conduct and convection heat transfer is negligible. The main parameters that influence the whole thermal performance of VIP is temperature, gas pressure, water content, core density, core granule and so on.
