摘　　要：以纵向翅片扁管换热器为研究对象,分析翅片长度、翅片高度及翅片间距对换热性能的影响,并对换热器的翅片结构参数进行优化,得出进口风速为2m/s时理想的翅片结构参数为:翅片长度为400mm、翅片高度为25mm、翅片间距为2.7mm。Taking the vertical fin and flat tube heat exchanger as a research exemple,the effects of the fin length,the fin height and the fin pitch upon the heat transfer performance were analyzed.At the same time,the fin structure parameters were also optimized.A group of better fin structural parameters were obtained when the import speed of wind is 2m/s.These optimized parameters were 400mm of fin length,25mm of fin height and 2.7mm of fin pitch.
