Study of Contact Thermal Resistance between Two Coaxial Cylindrical Layers(Ⅱ):Parameter Analysis
-
摘要: 應用同心圓柱套筒間接觸熱阻的三維穩態傳熱數學模型,分析了不同幾何形狀參數對收縮熱阻的影響,給出了收縮函數A的極限值表達式;還討論了熱物性參數和接觸面上的壓力對接觸熱阻的影響。Abstract: The mathematical model of three-dimensional steady-state heat conduction in the contact surface between two coaxial cylindrical layers is used for analysing the effects of geometric, mechanical and thermal parameters on the contact thermal resistance.The limit value of the constriction function A is found and the influence of contact pression is studied.
