摘　　要：为了分析不同车速下风扇的开启对汽车前端进风量的影响,通过CFD模拟了冷却模块上有无挡板两种情况下的进风量。随着车速的不断增加,风扇开启的增量越来越小,当车速达到一定速度后,风扇开启相对风扇关闭的进风量反而减少,风扇开启后起到了阻碍进风的作用。To analysis the influence of front end airflow at different speeds of vehicle and dif- ferent states of fan, the airflow of cooling module is simulated by CFD. With the increase of the speed of vehicle, the increase airflow is smaller and smaller. When the speed achieved a certain value, the airflow of fan switched on is less than the airflow of fan switched off. It will hinder front end airflowwhen fan switched on.
