| 摘 要： | 油冷器广泛应用于石化及各类机械加工过程中,新型高效油冷器的开发和研究有着重要意义。对不同结构参数的螺旋折流板冠形翅片管油冷器进行了实验研究,得到了油冷器的传热与阻力性能曲线,结果表明,油冷器的壳侧传热膜系数可达1 100—1 300 W/(m2.K),同时压降比弓形折流板光滑管降低30%—50%;传热管的翅片间距和翅片高度必须在合理的范围内,均在1.0—1.2 mm时,油冷器的性能较佳。

| Abstract: | Oil cooler is a kind of important equipment in industrial applications.The heat transfer and flow resistance performance of oil cooler with coronal fin tubes supported by helical baffles was studied.Experimental results indicate that heat transfer film coefficient in shell side of oil cooler is 1100-1300 W/(m~2·K),while pressure drop is 30%-50% lower than that of oil cooler with smooth tubes supported by segmental baffles.When fin patch P and fin height h are between 1.0 mm and 1.2 mm,the best heat transfer and flow resistance performance of oil cooler can be obtained. |
