The first is the process design, mainly is calculated according to the given design conditions, thus estimating heat exchanger area on the selection, checking heat transfer coefficient, calculate the actual transfer area, the pressure and temperature of the check calculation. The latter part of the design is about the heat exchanger and intensity of design, mainly is selected according to the heat exchanger type equipment parts (such as in a takeover, baffle plate and spacer pipe, tube, hook, etc., including: the design), the selection of materials, the size of the tube plate thickness, the calculation and sealing TouGai and head flange thickness calculation, opening reinforcement computation, etc. Finally the design can be shown through chart and assembly. Key words: Tubular heat exchanger，The tube plate，Baffle plate，Sealing head cover，Sealing head Flanges 目录 一. 概述················································1 二.确定设计方案，绘制工艺流程图
