AI Technical Summary
Technical Problem
The air guiding device in Patent Document 1 is complicated due to the inclusion of a plasma actuator, leading to a complex configuration.
Method used
An air duct with an inlet that opens forward and extends in the front-rear direction, an outlet that extends upward and covers the radiator, and inward-protruding protrusions on the upper wall that guide airflow to the radiator, utilizing the Coanda effect to direct airflow efficiently over a wider area.
Benefits of technology
The air duct achieves efficient airflow distribution over a wider radiator surface with a simpler configuration, minimizing interference with other vehicle parts.

Abstract
The simple configuration allows airflow to be directed over a wider area of the radiator's front surface. [Solution] The air duct 10 guides airflow to a radiator 90 located at the front of the vehicle. The longitudinal direction of the vehicle is defined as the longitudinal direction L, and the vertical direction of the vehicle when it is positioned on a horizontal plane is defined as the vertical direction Z. The air duct 10 has an inlet 20 that opens forward and extends in the longitudinal direction L, and an outlet 30 that is connected to the rear end of the inlet 20, extends upward and opens to the rear, and is provided to cover the front surface 91 of the radiator 90. The upper wall 21 of the inlet 20 has a connection portion 40 with the front wall 34 of the outlet 30, and a plurality of protrusions 43, 44 that project inward and extend in the vehicle width direction are provided at intervals in the longitudinal direction L. The protrusions 44 located further back are positioned higher.
