【正文】 essure drop is calculated must meet the technical requirement. The second part of the design is about the structure and intensity of the design. This part is just on the selected type of heat exchanger to design the heat exchanger’s ponents and parts, such as vesting, baffled plates, the distance control tube, tube boxes. This part of design mainly include: The choice of materials,identify specific size, identify specific location, the thickness calculation of tube sheet, the stress calculation of saddle, the opening reinforcement calculation etc. The results show that the pressbearing ponents can meet the intensity requirements. In the end, the final design results through eight drawings to display. Key words: fixed tube sheet heat exchanger； technology calculate； structure； intensity； tube sheet； saddle 安徽工程大學畢業(yè)設計（論文） III 目 錄 引 言
