本文对电传热实验系统的实验段——电加热圆管的壁温进行了分析计算,计算用实验作了验证,结果十分满意。据此编制的温度计算程序已为工程设计部门使用。实测电热管外壁温求解内壁温及温度分布的这一处理方法,原则上也适用于其它有电流通过的物体温度的确定。
In this paper, the experimental section of electric heat transfer experimental system - electric heating pipe wall temperature analysis and calculation, the calculation was verified by experiments, the results are very satisfactory. The resulting temperature calculation program has been used by the engineering department. Measured heating tube outer wall temperature and temperature to solve the temperature distribution of this treatment, in principle, is also applicable to other current through the object to determine the temperature.
