| 中文摘要: |
| 管板拥有比较复杂的受力情况，为确保水平管蒸发器能更好地承担压力，并且最大限度降低制造成本，管板的设计和改进显得更为迫切。将各种设计标准比较，选出较为适合水平管蒸发器薄管板设计计算的管板计算式，对新型薄管板的厚度进行预计算，根据经验得出预设管板厚度。利用ANSYS对改进后的水平管蒸发器进行强度分析，验证薄管板的厚度是否符合要求。经过分析得到的结果充分表明新型薄管板满足了设计要求，并且管子的扭曲变形度能够使水平管蒸发器在使用时满足布液要求，从而在保证蒸发效率的前提下，实现了水平管蒸发器的轻量化设计。 |

| Tube sheet has more complicated force situation，to ensure the horizontal tube evaporator can better bear the pressure and minimize manufacturing costs，the design and improvement of tube sheet is even more urgent. Comparing various design standards，selected more suitable formul for the design and calculation of the thin tube sheet of horizontal tube evaporator，precomputed for the thickness of the thin tube sheet，according to the experience the thickness of preset tube sheet was obtained. Intensity stress analysis of the improvement horizontal tube evaporator was carried out by ANSYS to verify whether the thickness of the thin tube sheet meet the requirements. The results through the analysis are fully indicated，the new thin tube sheet meets the design requirements, and the buckling deformation of the tube enables the horizontal tube evaporator meet the requirements of liquid distribution，under the premise of ensuring the evaporation efficiency, achieve the lightweight design of horizontal tube evaporator. |
