本文探讨了用热电摸拟实验法测定隔热壁平均导热系数,再用实测的客车壁温,反求隔热壁内外放热系数,从而确定隔热壁平均传热系数的方法。平均导热系数的实验结果与有限元法的计算值比较,证明导电纸热电模拟法具有足够的精度。此外,它还具有简单、经济、可靠等明显优点。 In this paper, the method of determining the average heat transfer coefficient of heat insulation wall by means of thermoelectric simulation experiment method is used to determine the average heat transfer coefficient of heat insulation wall. The experimental results of the average thermal conductivity are compared with those of the finite element method to prove that the thermoelectric simulation method of conductive paper has enough accuracy. In addition, it also has the obvious advantages of simple, economical, reliable and so on.
