Abstract

The invention concerns a structure ( 2 ) of a system ( 1 ) for managing the air of an air inlet for the front panel of a motor vehicle, said structure ( 2 ) comprising:—a frame ( 3 ) intended to be positioned facing a heat exchanger (Ra), —one or more deflectors ( 7 ) that are secured to said frame ( 3 ) and are arranged in such a way as to intercept a flow of air and deflect it through said frame ( 3 ). The invention also concerns a system ( 1 ) for managing the air of an air inlet for the front panel of a motor vehicle having such a structure ( 2 ).

First claim

The invention claimed is:

1. A structure of an air inlet air management system for the front panel of a motor vehicle wherein said air inlet air management system comprises: a mouth defining the air inlet and at least one flap, arranged at the mouth, which in at least one open position, is arranged to direct the incoming air flow towards a frame, and wherein one or more deflectors are arranged so that, in said open position of the at least one flap, said one or more deflectors intercept an air flow directed by said at least one flap and divert air flow through said frame, said structure comprising:
the frame positioned in facing contact with a heat exchanger; and
the one or more deflectors, which are rigidly connected to said frame and are arranged so as to intercept the air flow and divert the air flow through said frame,
wherein said one or more deflectors are each in the form of a fin projecting from said frame heightwise in the internal space of the duct, and extending longitudinally along the direction of the longitudinal axis of said at least one flap.

2. The structure as claimed in claim 1 , having several deflectors distributed along said frame and spaced apart from each other along the direction of the duct.

3. The structure as claimed in claim 2 , wherein the spacing between two consecutive deflectors increases the further away from said air inlet the consecutive deflectors are.

4. The structure as claimed in claim 1 , further comprising:
a first element defining said frame,
a second, removable, element forming a cowling covering said frame, a duct being at least partially defined by the inter-space formed the first element and the second element,
means of assembly between the first element and the second element,
and wherein said deflector or deflectors are elements integral with the body of the first element.

5. The structure as claimed in claim 4 , wherein said first element is a molded part, said deflector or deflectors being obtained during the molding of the part.

6. The structure as claimed in claim 1 , wherein each deflector has a curved cross section so as to intercept and adjust the air flow directed through said frame.

7. An air inlet air management system for a front panel of a motor vehicle, the system comprising:
a structure comprising:
a frame positioned in facing contact with a heat exchanger; and
one or more deflectors, which are rigidly connected to said frame and are arranged so as to intercept an air flow and divert the air flow through said frame; and

a mouth defining said air inlet,
wherein said air management system has at least one flap, arranged at the mouth, which, in at least one open position, is arranged so as to direct the incoming air flow towards said frame,
wherein said deflector or deflectors are arranged so that, in said open position of the at least one flap, said deflector or deflectors intercept the air flow directed by said at least one flap and divert air flow through said frame, and
wherein said deflector or deflectors are each in the form of a fin projecting from said frame heightwise in the internal space of the duct, and extending longitudinally along the direction of the longitudinal axis of said at least one flap.

8. The system as claimed in claim 7 , wherein said at least one flap is a flap mounted pivoting on a support of the structure, and wherein the hinge axis of the flap is centered on the width of the effective area of said at least one flap.

9. The system as claimed in claim 7 , having several flaps, which at least in their open position are arranged so as to direct the incoming air flow towards said frame.

10. A method for cooling a heat exchanger of an air inlet air management system for a front panel of a motor vehicle, the air inlet air management system comprising:
a structure comprising:
a frame positioned in facing contact with a heat exchanger; and
one or more deflectors, which are rigidly connected to said frame and are arranged so as to intercept an air flow and divert the air flow through said frame; and

a mouth defining said air inlet,
at least one flap, arranged at the mouth, which, in at least one open position, is arranged to direct the incoming air flow towards said frame, and
wherein said deflector or deflectors are arranged so that, in said open position of the at least one flap, said deflector or deflectors intercept the air flow directed by said at least one flap and divert air flow through said frame,
the method comprising:
orienting said at least one flap, in said at least one open position, so as to direct the incoming flow towards the deflector or deflectors and evenly distribute the flow over the different zones of the frame that are delimited by said deflector or deflectors.
