导热率
thermal conductivity
dOOre!U导热率(thermal conduetivity)傅里叶定律表述式中热流通量矢量q与温度降度一gradT的比值，即 q一gradT它表征物质导热能力的大小，又称导热系数，是物质的一个重要热物性参数。导热率的数值就是物体中温度降度为IK/m时，单位时间内通过单位面积的导热量，它的单位是W/(m·K)，是物质的性质，与物体的尺寸大小无关。热导率却与导热路径长短和导热面积大小有关，是导热热阻的倒数。导热率与热导率，正像电工中导电率与电导率一样，是两个不同的概念，不应混淆。 各种工程常用物质的导热率相差十分悬殊，纯金属材料的最大，气体和蒸汽的最小，非晶体的热绝缘材料和无机液体的介于它们之间。下面列出室温条件下一些典型物质的导热率数值范围: 金属50~415W/(m .K) 合金12一12ow/(m·K) 非金属液体。一7~0.7W/(m·K) 热绝缘材料0.03~0.ZW/(m·K) 大气压下的气体。.007~o.17w/(m·K) 不同物质导热率的差异是由于物质的物理化学结构不同所致。此外，导热率还和物质的温度、密度和湿度等因素有关，其中温度对导热率的影响尤为重要。对于许多工程材料，导热率的数值都由实验确定，在一定的温度范围内，它可以认为是温度的线性函数，即人-凡(l+bt)，其中凡是t一。C时的导热率;b是实验常数。 气体的导热率随温度升高而增大，除非压力很低(<300Pa)或压力很高(>Zo0MPa)，可以认为它与压力无关。大多数纯金属的导热率随温度升高而减小。金属中掺人任何杂质都将使导热率减小。对于非缔合或弱缔合液体.导热率随温度升高而下降。 通常将导热率小于0.ZW八m .K)的材料称为热绝缘材料，它们都是多孔体或纤维性材料，严格地说，它们不再是连续均匀介质，其导热率只能是表观的导热率，温度、湿度和密度对其有较大的影响。 石英、石墨和木材等各向异性材料的导热率还与材料取向有关。
