摘要:螺旋隔板换热器主要包括两种不同类型的结构形式,即没有中心管的非整体连续的螺
旋隔板换热器和有中心管的整体连续的螺旋隔板换热器。本文总结了国内外学者对螺旋隔板换热
器所做的主要研究工作,这包括壳程流体的动力学研究、传热与压降性能研究和数值模拟,并介绍
了整体连续型螺旋隔板强化管换热器在工业中的应用。最后,对螺旋隔板换热器的下一步研究工
作进行了展望。

Abstract :The helical baffled heat exchanger mainly includes two kinds of different geometry designs The first
is that helical baffles are not integrally continuous and a central tube is not placed in the exchanger. The sec
ond is that helical baffles are integrally continuous and a central tube is placed in the exchanger The research
works concerning hydrodynamic studies , and heat transfer and pressure drop testes and numerical simulations
in the shell side of helical baffled heat exchangers are reviewed. The application of the helical baffled heat ex
bined with different enhanced tubes are presented Eventually , the expected aspects of further in
vestigations on helical baffled heat exchangers are put forward
Key words :shell - and - tube heat exchan
