Abstract：The present paper detailedly introduces the design and manufacture process of fixed plate heat exchanger. It’s model is defined based on the physical parameters of fluid and the amount which is required in production, making use of calculation of fundamentals about heat transfer process. Then, designe the structure and strength about most of components in heat exchanger, including a thick-shaped part of the body, the case of tube pass, head , baffle, tube sheet and so on, according to the standards, such as GB150-1998 Steel Pressure Pessels and GB151-1999 Tubular Heat Exchangers. Tubesheet is the most important part, which is used to connect shell, tube bundle and channeland bear pressure, temperature load and other loads. Especially, about tube sheet, it is calculated、integrated and calibrated about stress,in order to security. In the section of manufacture,there is a simaple flow chart that clearly show the order of manufacture and installation of spare parts. And there are some concrete requirements about the joint of tube to tube sheet and manufacture technology of tube sheet.
Key words: Fixed plate heat exchanger; Tube sheet; Baffle; head
