摘　　要：简介了管壳式换热器设计中Ｔｉｎｋｅｒ模型及Ｂｅｌｌ－Ｄｅｌａｗａｒｅ方法￣［１，２］，讨论了换热器结构性能优化的方法，建立了数学模型￣［３］，编制了计算程序。为工厂分别优化设计了无相变气—水换热器和有相变汽—水加热器。其结果表明，优化后的管壳式换热器，在同样的操作条件下，重量减轻了２０％～３０％，经济效益可观。In this paper,an introduction of Tinker Model and Bell-Delaware Meth-od used for shell and tube heat exchanger design is given,an optimization methodfor the structural function of heat exchanger is discussed.The mathematical methodand relative calculation programs are established,which bave been successfully appliedto the desigh of steam-water heat exchanger with and without phase change.The re-sults show that the weight has been reduced by 20 to 30 percent for the optimized heatexchanger under the same working conditions, which is of great economic benefit.
