在板式换热器优化设计过程中，涉及到的变量较多，对有些变量的取值范围有界限约束，比如流速。本文从流速对换热效果和压力的影响出发，建立热力学模型，在基本粒子群算法上做了改进，利用此改进的粒子群算法对板式换热器流速受限的情况进行优化设计，解决了板式换热器中流速受到约束时的成本优化问题。
在闆式換熱器優化設計過程中，涉及到的變量較多，對有些變量的取值範圍有界限約束，比如流速。本文從流速對換熱效果和壓力的影響齣髮，建立熱力學模型，在基本粒子群算法上做瞭改進，利用此改進的粒子群算法對闆式換熱器流速受限的情況進行優化設計，解決瞭闆式換熱器中流速受到約束時的成本優化問題。

In the optimization process of plate heat exchanger(PHE), many variables were involved, there were boundary constraints for some of these variables, such as flow rate. In this article,starting from the effect of the flow rate on heat transfer and pressure, thermodynamic model was built. Improvements have been made on the basis of elementary particle swarm optimization. The improved particle swarm algorithm was used in the plate heat exchanger optimization design, successful resolved the problem of plate heat exchanger cost optimization design with a constrained flow rate.
