【Abstract】 In this paper,an introduction of Tinker model and Bell-Delaware method used for shell and tube heat exchanger design is given , an optimization method for the structural function of heat exchanger is discussed. The mathmatical model and relative calculation programs are established, which have been successfully applied to the design of steam-water heat exchanger with and without phase change. The results show that the weight has been reduced by 20% to 30% for the optimized shell and tube heat exchanger under the same workingconditions, economic benefit is great.更多还原
