摘要
本文提出管壳式换热器壳侧支撑结构的一种新形式——花隔板。为研究花隔板换热器的换热和流阻性能,利用相似原理进行相关实验,得到花隔板换热器的换热准则关系式和流动阻力准则关系式。与传统单弓形折流板换热器进行比较,花隔板换热器的综合性能K/Δp提高10%～30%。
A new kind of support structure in shell side of tube and shell heat exchanger named flower baffle is discussed in this article.Experiment based on similarity principle has been taken in order to investigate the performance of heat transfer and flow resistance,the criteria relationship expressions of heat transfer and flow resistance are obtained.The integrated performance K/Δp of flower baffle heat exchanger increases 10%～30% compared with that of plane baffle heat exchanger.
