On the fixed plate heat exchanger for an indepth study, first of all, in the heat exchanger overall structure, its cylinder, head for calculating the thickness and intensity of the check, has been in the diameter DN1000, nominal pressure specific reasonable under the cylinder head and the thickness of the box and tube and a receiver for the selection and opening reinforcement check. Secondly, in the heat exchanger aspects of the internal structure of the calculation of the Tube and pipe layout, the cloth in accordance with the correct method of calculating the heat exchanger for the 1000mm diameter of the tube plate implementation of the singletube process, singleshell calculation under the conditions of the cloth and draw the corresponding CAD map of the cloth. At the same time with BS Law on the thickness of the plate and check the calculation. Throughout the design process, but also includes some other parts of the design and selection, but also to the overall manufacture and installation of an analysis. Finally get a plete set of fixed plate heat exchanger of the structural
