Abstract

Car provided with: at least one radiator; a ventilation channel which houses on the inside the radiator; an aerodynamic duct, which extends between an inlet opening and an outlet opening obtained inside the ventilation channel between the inlet opening of the ventilation channel and the radiator; and a shutter, which is arranged in the area of the inlet opening of the aerodynamic duct and is mounted mobile between an engagement position, in which the shutter closes the inlet opening of the aerodynamic duct, and a disengagement position, in which the shutter leaves the inlet opening of the aerodynamic duct free.

Claims

1. A car comprising:

at least one radiator; and

a ventilation channel, which houses on the inside the radiator and extends between an inlet opening, thorough which fresh air flows in, and an outlet opening, through which hot air flows out;

wherein the car comprises;

a first aerodynamic duct, which extends between an inlet opening, which is arranged next to the inlet opening of the ventilation channel, and an outlet opening, which is obtained inside the ventilation channel between the inlet opening of the ventilation channel and the radiator; and

a shutter, which is arranged in correspondence to the inlet opening of the first aerodynamic duct and is mobile between an engagement position, in which the first shutter closes the inlet opening of the first aerodynamic duct, and a disengagement position, in which the first shutter leaves the inlet opening of the first aerodynamic duct free.

2. A car according to claim 1, wherein the shutter is mounted so as to rotate around a rotation axis between the engagement position and the disengagement position.

3. A car according to claim 1, wherein the rotation axis of the first shutter is arranged vertically.

4. A car according to claim 1 and comprising an elastic element, which pushes the first shutter towards the engagement position with a calibrated elastic force.

5. A car according to claim 4, wherein the calibrated elastic force generated by the elastic element is such that the aerodynamic pressure of the air determines the movement of the first shutter from the engagement position to the disengagement position when the car exceeds a predetermined speed threshold.

6. A car according to claim 4, wherein the elastic element consists of a torsion spring.

7. A car according to claim 1, wherein:

a car body is provided, which has a front bumper; and

the inlet opening of the ventilation channel and the inlet opening of the first aerodynamic duct are obtained one next to the other through the front bumper.

8. A car according to claim 7, wherein the first aerodynamic duct is entirely obtained through the front bumper.

9. A car according to claim 1 and comprising:

two twin ventilation channels, which are arranged on opposite sides of the car; and

two aerodynamic ducts, each of which leads to the inside of a corresponding ventilation channel and is coupled to a corresponding first shutter.

10. A car according to claim 9, wherein the inlet openings of the two first aerodynamic ducts are arranged one next to the other in a central position, namely between the inlet openings of the two ventilation channels.

11. A car according to claim 10, wherein the inlet openings of the two first aerodynamic ducts are separated from one another by a separating body with a triangular section.

12. A car according to claim 1, wherein the outlet opening of the first aerodynamic duct is arranged close to the inlet opening of the ventilation channel.

13. A car according to claim 1, wherein the end part of the first aerodynamic duct in correspondence to the outlet opening of the first aerodynamic duct itself is oriented transversely to the ventilation channel.

14. Car according claim 1 and comprising:

a car body which has a front bumper;

a lower side which delimits the car at the bottom and faces the road surface; and

at least one second aerodynamic duct, which is completely independent and separate from the ventilation channel and from the first aerodynamic duct, extends between an inlet opening, which is arranged frontally in order to be struck by the aerodynamic pressure of the air when the car moves forward, and an outlet opening obtained through the lower side of the vehicle in order to face the road surface; and

a second shutter, which is arranged in the area of the inlet opening of the second aerodynamic duct and is mounted mobile between an engagement position, in which the second shutter closes the inlet opening, and a disengagement position, in which the second shutter leaves the inlet opening free.

15. Car according to claim 14 and comprising a second elastic element which pushes the second shutter towards the engagement position with a calibrated elastic force.
