摘　　要：对连续螺旋折流板换热器和弓形折流板换热器壳侧的传热性能及阻力性能进行了实验研究,得出了壳侧阻力和换热的关联式,并将其和非连续螺旋折流板换热器进行了比较。研究发现,在壳侧流速较大时,连续螺旋折流板换热器的传热性能优于弓型折流板换热器和非连续螺旋折流板换热器。This paper investigated the flow and heat transfer characteristics for shell-and-tube heat exchangers with continuous helical baffles and segmental baffles. The resistance factor and heat transfer correla-tions for shell-side regions have been obtained. The comparison among heat transfer exchangers with continuous helical baffles, segmental baffles and non-continuous helical baffles has been made, and it is found that the heat exchangers with continuous helical baffles is superior to the heat exchangers with segmental baffles and non-continuous helical baffles when the shell-side velocity increased.
