"固定管板式换热器设计：结构、强度计算与装配工艺详解"

The article "固定管板式换热器设计.pdf" discusses the structural design process of a fixed tube sheet heat exchanger based on known parameters such as the heat transfer area and shell diameter. It follows the standards of GB150-1998 "Steel Pressure Vessels" and GB/T 15199 "Shell and Tube Heat Exchangers" to determine the tube type and tube layout of the heat exchanger. The stress calculations and strength checks for the main pressure components such as the shell, heads, and tube sheets are conducted, and other parts such as tie rods, spacers, and anti-vibration plates are selected. The article also provides explanations for the manufacturing, assembly, and maintenance of the heat exchanger, ultimately concluding that the design is reasonable. Furthermore, the article utilizes AutoCAD to create assembly and component drawings of the fixed tube sheet heat exchanger, and uses UG for 3D modeling and simulation of its assembly process. This provides valuable references for the actual production and assembly of heat exchangers. Key words include heat exchanger, heat transfer area, tube sheet, design, fixed tube sheet heat exchanger.
