Embodiment Construction
[0034] When the car is running, the outside air of the car enters the engine compartment through the grille to cool the radiator in the engine cooling system to ensure the normal operation of the engine cooling system. The grilles of vehicles are usually designed with different appearances. , The opening of the grille usually only has two states of opening and closing. On some high-end cars, the opening of the grille can be automatically opened or closed according to the engine temperature and the pressure of the vehicle's air conditioning system.
[0035] However, in the prior art, the vehicle speed is not considered when the cooling system is realized by opening or closing the grille. In fact, when the vehicle speed is fast, if the grille is opened, although the effect of heat dissipation can be achieved, But this will also lead to a higher drag coefficient of the vehicle. When the speed of the vehicle is fast, it is the best time to reduce the drag coefficient through the c...
