【摘要】 结合异形竖板降膜蒸发器，研究了异形竖板传热元件壁面温度的测量方法。从整个测温系统入手，分别阐述了测温元件的选择、热电偶的焊接及敷设等方法；并给出一种测量非等温场望面平均温度时，对称互补式热电偶敷设的新方法。达到了准确测量壁面温度的目的，对异形竖板降膜蒸发器的传热理论研究具有重要的意义。更多还原

【Abstract】 This paper researches the surface temperature measuring methodfor special vertical-plate heat-transfer element together with the special vertical-plate down film evaporator. From all measuring temperature system, thechoice of measuring temperature element, and the methods of the thermocoupleweld and its arrangement are introduced. The new method for symmetric thermocouple arrangement is given when the averaging temperature of the specialvertical plate with non-equal temperature field. It can accurately measure thesurface temperature and is very important for heat-transfer theory about thevertical-plate down film evaporator to research.更多还原
