传热学：热阻热阻：反映阻止热量传递的能力的综合参量。在传热学的工程应用中﹐为了满足生產工艺的要求﹐有时通过减小热阻以加强传热﹔而有时则通过增大热阻以抑制热量的传递。 当热量在物体内部以热传导的方式传递时﹐遇到的热阻称为导热热阻。对於热流经过的截面积不变的平板﹐导热热阻为L /(A )。其中L 为平板的厚度﹐A 为平板垂直於热流方向的截面积﹐为平板材料的热导率。 在对流换热过程中﹐固体壁面与流体之间的热阻称为对流换热热阻﹐1/(A )。其中为对流换热係数﹐A 为换热面积。两个温度不同的物体相互辐射换热时的热阻称为辐射热阻。如果两个物体都是黑体(见黑体和灰体)﹐且忽略两物体间的气体对热量的吸收﹐则辐射热阻为1/(A 1F 1-2)或1/(A 2F 2-1)。其中A 1和A 2为两个物体相互辐射的表面积﹐F 1-2和F 2-1为辐射角係数。 当热量流过两个相接触的固体的交界面时﹐界面本身对热流呈现出明显的热阻﹐称为接触热阻。產生接触热阻的主要原因是﹐任何外表上看来接触良好的两物体﹐直接接触的实际面积只是交界面的一部分(见图 接触热阻示意图 )﹐其餘部分都是缝隙。热量依靠缝隙内气体的热传导和热辐射进行传递﹐而它们的传热能力远不及一般的固体材料。接触热阻使热流流过交界面时﹐沿热流方向温度 T 发生突然下降﹐这是工程应用中需要儘量避免的现象。减小接触热阻的措施是﹕增加两物体接触面的压力﹐使物体交界面上的突出部分变形﹐从而减小缝隙增大接触面。在两物体交界面处涂上有较高导热能力的胶状物体──导热脂。
