一种多股流换热器综合性能优化设计方法

在综合考虑了体积、重量和阻力等因素的基础上，对多股流换热器进行通道排列和优化设计，并运用无量纲分析法，自定义了syn因子、syn线等用以评价换热器综合性能的指标。详细分析了应用syn因子综合优化翅片结构的过程，与实际的设计结果比较表明：该方法适用于多股流换热器的综合性能优化设计。

Comprehensive-performance Optimization Design Method for Multi-stream Heat Exchangers

On the basis of a comprehensive consideration of such factors as volume, weight and resistance, etc a flow channel layout and an optimized design were carried out for a multi stream heat exchanger. Moreover, a dimensionless analytical method is applied to define a synthesis (syn) factor and synthesis line, etc in order to evaluate the comprehensive performance of the heat exchanger. A detailed analysis is performed of the process of fin structure comprehensive optimization by making use of the synthesis factor. A comparison of the analysis results with design ones indicates that the method under discussion is suitable for the comprehensive performance optimization design of the multi stream heat exchangers.
