管程隔板

管程隔板是安装在管壳式换热器管板或管箱内的结构部件，用于形成多个管程。它们引导管侧流体按预定顺序通过特定的管束区段，控制流道长度和流速，以实现所需的传热系数和温度分布。这些隔板经过精密设计，能够承受热膨胀、压差和腐蚀环境，同时保持相邻管程之间的密封性。

管程隔板通过将管侧管箱物理分隔成多个隔室，迫使工作流体在流出前多次穿过管束。这种多管程布置提高了流体速度和停留时间，增强了对流换热系数。隔板形成串联流道，优化了对数平均温差（LMTD），并防止流体旁流，确保换热器表面热负荷均匀。

Pass partitions function by physically dividing the tube-side header into compartments, forcing the working fluid to traverse the tube bundle multiple times before exiting. This multi-pass arrangement increases fluid velocity and residence time, enhancing convective heat transfer coefficients. The partitions create serial flow paths that optimize logarithmic mean temperature difference (LMTD) and prevent fluid bypassing, ensuring uniform thermal loading across the heat exchanger surface.
