管型对螺旋折流板翅片管油冷器性能的影响
EFFECTS OF TUBE TYPE ON THE PERFORMANCE OF OIL-COOLER WITH FIN TUBES SUPPORTED BY HELICAL BAFFLES
摘要
Abstract
Oil cooler is widely used in the chemical engineering process and machining process. Effect of different tubes on the heat transfer and flow resistance performance of oil cooler with coronal fin tubes suported by helical baffles was studied in this paper. The results indicate that heat transfer film coefficient in shell side of oil cooler could be 1 100～1 300W/(m2·K), which is 2 times as that of oil cooler with smooth tubes supported by segmental baffles, while pressure drop is 30%～50%. To obtain an optimal performance of oil cooler, the fin patch P and fin height h must be dept in a rational range, that is between 1.0～1.2mm.关键词
