摘要
印刷电路板式换热器具有重量轻、体积小,紧凑度高和传热性能好等优点,非常适合用作舰用燃气轮机间冷器.本文针对舰用燃气轮机用的印刷电路板式间冷器进行了优化设计与分析,建立了印刷电路板式间冷器优化问题的数学模型,通过遗传算法的全局优化搜索能力分别以压降最小、质量最轻和紧凑度最高为目标进行间冷器结构参数优化,分析了固定热负荷条件下改变热侧工质质量流量对间冷器性能的影响.结果表明,单目标优化后的间冷器总压降减少了 81.52％,总质量减轻了 77.66％,紧凑度提高了 69.10％.
Abstract
Printed circuit heat exchangers,with advantages such as lightweight,compact size,high compactness,and excellent heat transfer performance,are highly suitable for use as intercoolers in marine gas turbines.In this paper,the optimization design and analysis of the printed circuit plate intercooler for marine gas turbine are carried out,and the mathematical model of the optimization problem of the printed circuit plate heat exchanger is established.The global optimization search ability of the genetic algorithm is used to optimize the structural parameters of the heat exchanger with the minimum pressure drop,the lightest mass and the highest compactness as the objectives respectively.The influence of changing the mass flow rate of the hot side working medium on the performance of the heat exchanger under the condition of fixed heat load is analyzed.The results indicate that the optimized intercooler achieved an 81.52％reduction in total pressure drop,a 77.66％reduction in total mass,and a 69.10％increase in compactness compared to the pre-optimization values.
