Abstract
In a ventilation duct of a cooling system, a level difference is formed between a wall located on a vehicle front side and a wall located on a vehicle rear side because a bottom end of the wall located on the vehicle front side is lower than a bottom end of the wall located on the vehicle rear side. The level difference makes a speed of a traveling wind flowing near an outlet faster than that flowing away from the outlet. Therefore, a pressure of the traveling wind flowing near the outlet decreases. As a result, air flows in the ventilation duct to be drawn to the neighborhood of the low-pressure outlet, and discharged out. Because cooling air including the traveling wind can be increased, heat radiation capacity of a radiator disposed in the ventilation duct is improved, and the cooling capacity of the cooling system can also be improved.
