The invention provides an airflow adjusting device and an automobile. The airflow adjusting device comprises an airflow channel extending in the length direction of an automobile body. The airflow channel is provided with a separation flow inlet and an airflow outlet; the separated flow inlet is close to the headstock; the airflow outlet is close to the tailstock; the airflow adjusting device further comprises a turbine arranged in the airflow channel and a driving device for driving the turbine to rotate. In use, airflow exits the airflow outlet at an acute angle to the vehicle body. According to the technical scheme, the airflow adjusting device can convert separated flow on the surface of the vehicle body into uniform and stable laminar flow in the running process of the vehicle, the laminar flow is attached to the surface of the vehicle body again to flow, the influence of the separated flow on the wind resistance of the whole vehicle is effectively reduced, the wind resistance coefficient of the whole vehicle is greatly reduced, and then the endurance mileage of the vehicle is increased.

    本申请提供了一种气流调整装置及汽车,该气流调整装置包括沿车身长度方向延伸的气流通道;气流通道具有分离流入口及气流出口;分离流入口靠近车头,气流出口靠近车尾;气流调整装置还包括设置于气流通道中的涡轮以及驱动涡轮转动的驱动装置;在使用中,气流与所述车身呈锐角离开气流出口。在上述技术方案中,气流调整装置可以使车辆行驶过程中车身表面的分离流转化为均匀稳定的层流,并重新贴附车身表面流动,有效减少分离流对于整车风阻的影响,大幅降低了整车风阻系数,进而提升车辆续航里程。
