摘要：对混合管束滑油冷却器和光管滑油冷却器进行对比试验研究，发现当滑油体积流量相同时，前者单位体积换热量较高，压降较小，换热能力强，综合性能优越，表明在同样换热量条件下可以使冷却器小型化。关键调：冷油器；双流程；整体针翅管；混合管束；强化换热

Abstract:A lot of comparison experimental research has been done to the lubricating-oil cooler with mixing integral pin-fin tubes and plain tubes . It is discovered that the mixing integral pin-fin tubes heat transfer capacity in unit volume is higher, pressure drop is lower, and the very strong heat transfer ability than plain tubes when oil volume flow rate is at constant value. The results show the performance of lubricating-oil cooler with mixing integral pin-fin tubes and plain tubes is superiority. So this can made lubricating oil cooler miniaturize in the same Heat changing condition.
Key words:oil cooler; double-flow;integral pin-fin tube;tubes mixed bundle;heat trans-fer enhancement
