    摘要
  • 摘要: 通过搭建法兰接触热阻实验台，在法兰间隙0~0.75 mm、螺栓拧紧力矩20~40 N?m参数范围内，测量不同材料机匣多个轴向位置的壁温来获得通过法兰的热流，得到法兰的接触热阻、单位接触热导。分析了法兰间隙、螺栓拧紧力矩对法兰接触热阻特性的影响。研究结果表明随着法兰间隙的增加，接触热阻呈线性增加，最大增加0.03 K/W，单位接触热导先迅速减小，后趋于平缓，最大降低了10 744.2 W/(K?m2)，约94.5%；随着拧紧力矩的增加，接触热阻减小，最大降低了22.1%。

     

    Abstract: By setting up a flange contact thermal resistance experimental bench，within the range of 0-0.75 mm of flange clearance and 20-40 N?m of bolt tightening torque，the wall temperature of multiple axial positions of casing of different materials was measured to obtain the heat flux passing through the flange，and the contact thermal resistance and unit contact thermal conductivity of the flange were obtained.The influences of flange clearance and bolt tightening torque on the contact thermal resistance of flange were analyzed.The results showed that with the increase of flange clearance，the contact thermal resistance increased linearly，the maximum increase was 0.03 K/W，the unit contact thermal conductivity decreased rapidly at first，and then was inclined to smooth，with the maximum reduction of 10 744.2 W/(K?m2)，about 94.5%；with the increase of tightening torque，the contact thermal resistance decreased，the maximum reduction was 22.1%.
