摘　　要：为了解决车用空-空中冷器内部气体流动均匀性差的问题,提出了复合混流式中冷器的概念。基于计算流体力学(CFD)方法和试验方法,对基准模型中冷器和复合混流式中冷器的性能进行对比分析。结果表明:在相同的工况条件下,将基准模型中冷器更换为优化结构中冷器,发动机的功率将增加1.54 kW。In order to solve the poor flow uniformity inside air-to-air charge air cooler(CAC),a composite mixed-flow concept was proposed.Based on the computational fluid dynamics(CFD)and experimental methods,the performances of reference model and composite mixed-flow CAC were compared and analyzed.The results show that engine power improves by 1.54 kW with the optimized CAC instead of the reference model CAC under the same working condition.
