由于螺旋折流板管壳式换热器具有较低的壳程压降、较低的抗污垢能力以及较低的运行和维护成本，因此对其性能进行了许多研究。但由于小尺寸模型带来的额外影响，这些研究扩展到实际应用受到限制。本文对带重叠螺旋折流板和分段折流板的管壳式油冷却器的性能进行了实验比较，两种油冷却器均为实用产品。结果表明，在固定体积流量下，OCHB（带螺旋折流板的油冷却器）比OCSB（带扇形折流板的油冷却器）具有更低的壳程压降和更高的单位压降传热系数。根据实验数据，可以预测，通过适当的设计，OCHB可以获得比OCSB更好的传热性能。本研究对于OCSB和OCHB的设计和实际运行是有益的。
Many research studies have been conducted on the performance of shell and tube heat exchanger with helical baffles because of its lower shell-side pressure drop, lower fouling resistance and lower operation and maintenance cost. But the extension of those studies into practical application is limited because of the additional effects caused by the small-size model. In this paper, the performance of shell-and-tube oil coolers with overlapped helical baffles and segmental baffles is compared experimentally, and both of the oil coolers are practical products. The results show that the OCHB (Oil Cooler with Helical Baffles) gets lower shell side pressure drop and higher heat transfer coefficient per unit pressure drop at fixed volume flow rate than the OCSB (Oil Cooler with Segmental Baffles). Based on the experimental data, it can be predicted that with proper design the OCHB can get better heat transfer performance than OCSB. The present studies are beneficial for the design and practical operation of OCSB and OCHB.
