通过理论分析和实际计算,讨论了翅片节距对翅片性能的影响,并对不同种类、不同规格翅片的性能进行了比较,得出结论:在同样翅片高度的情况下,翅片节距变小、性能有提高的趋势,所以所有翅片应向节距小的方向发展;适当高度和节距的多孔形翅片,性能不亚于锯齿形翅片;同一种翅片在不同的场合使用,会表现出不同的特性。 Through the theoretical analysis and practical calculation, the influence of the fin pitch on the performance of the fin was discussed, and the performance of the different kinds and different specifications of the fin was compared. It was concluded that at the same fin height, the fin Pitch smaller, performance tends to increase, so all the fins should be in the direction of small pitch; the appropriate height and pitch of the porous fins, the performance of no less than serrated fins; the same fins in different The use of occasions, will show different characteristics.
