摘要：

提出一种新型扭曲三叶管纵流油冷却器强化传热方案，对其壳程的传热与压降特性与扭曲椭圆管油冷却器和传统折流板油冷却器进行了实验对比分析。结果显示，在相同油流量下，扭曲三叶管油冷却器壳程的传热系数、压降和传热系数比压降值（h/?p）分别比传统折流板油冷却器高138.7%~90.5%、19.6%~37.8%和77.2%~130.4%；分别比扭曲椭圆油冷却器高257.8%~298.6%、140.5%~158.4%和40.1%~65.7%，表明扭曲三叶管油冷却器具有很好的强化传热效果。并对其强化传热机理进行了分析，在壳程雷诺数（Re）为80~550的范围内，拟合获得了扭曲三叶管和扭曲椭圆管两种纵流油冷却器壳程努塞尔数（Nu）和摩擦因子（f）关联式。

Abstract:

In this paper, a heat transfer enhancement scheme for the novel twisted trifoliate tube longitudinal flow oil cooler was proposed. The heat transfer and pressure drop performance of the shell side of twisted trifoliate tube oil cooler was experimentally investigated and compared to the twisted oval tube oil cooler and conventional segmental baffle oil cooler. The experimental results showed that under the same oil flow rate, the shell-side heat transfer coefficient, pressure drop and h/?p of the twisted trifoliate tube oil cooler were 138.7%—190.5%, 19.6%—37.8% and 77.2%—130.4% higher than that of the conventional segmental baffle oil cooler, and were 257.8%—298.6%, 140.5%—158.4% and 40.1%—65.7% higher than that of the twisted elliptical tube oil cooler, respectively. The results proved the twisted trifoliate tube oil cooler had a good heat transfer enhancement effect. The mechanism of heat transfer enhancement was also analyzed. Based on the experimental data, the correlations of Nu and f on the shell side of twisted trifoliate tube and twisted oval tube oil cooler were deduced with Re ranging from 80 to 550.

Key words: low Re, longitudinal flow heat exchanger, twisted trifoliate tube, oil cooler, heat transfer enhancement
