探讨利用列车行驶风直接冷却增压空气的空 空冷却器行驶风中冷器 ,其性能远优于水冷中冷器 ;提出应将出气温度作为评价中冷器性能的另一关键性指标 It is discussed that the performance of air-cooled intercooler is better than that of watercooled intercooler because of the direct cooling of supercharged air by train traveling wind. It is suggested that the outlet air temperature should be taken as another key index to evaluate the performance of intercooler
