Abstract

The invention relates to a housing (3) for a front face module (2) of a motor vehicle (1), defining an air duct (4) for the flow of an air stream, said housing comprising: —an openwork structure (30) having a plurality of openings (32) defined by ribs (34); —a lining (36) which is securely attached to the openwork structure (30) and covers the openings (32) so as to form a wall which is airtight to the air stream. The invention also relates to a method for manufacturing such a housing and to a front face module (2) comprising such a housing.

First claim

1 . A housing for a front-end module of a motor vehicle, defining a flow duct for the flow of an air stream, said housing comprising;
a perforated structure comprising a plurality of openings delimited by ribs; a skin secured to the perforated structure, covering the openings so as to form a wall impervious to the air stream.

2 . The housing as claimed in claim 1 , wherein the perforated structure comprises at least 5 openings all delimited by the ribs.

3 . The housing as claimed in claim 1 , wherein the openings are at least partially arranged in a repeated pattern.

4 . The housing as claimed in claim 1 , wherein the ribs are at least partially arranged in a triangular mesh.

5 . The housing as claimed in claim 1 , wherein the thickness of the perforated structure is between 1 and 3 mm and the thickness of the skin is between 0.3 and 1 mm.

6 . The housing as claimed in claim 1 , wherein the perforated structure is made of a first material and the skin is made of a second material, the first and second materials being of different compositions.

7 . The housing as claimed in claim 1 , wherein the skin comprises an internal cavity.

8 . The housing as claimed in claim 1 , wherein the perforated structure is made of several parts not forming continuity of material, each part being secured to one another via the skin.

9 . A method for manufacturing a housing for a front-end module of a motor vehicle, defining a flow duct for the flow of an air stream, the housing having a perforated structure in a first material, the method comprising:
preheating at least one layer of skin of a second material different from the first material, the second material being an acoustic insulation material; shaping said at least one layer of skin; positioning said at least one layer of skin in an injection mold; overmolding the perforated structure at least around said at least one layer of skin by injecting the first material into the injection mold; and demolding.

10 . A front-end module comprising a housing for a front-end module of a motor vehicle, defining a flow duct for the flow of an air stream the module comprising:
an air inlet and an air outlet; at least one heat exchanger being arranged within the flow duct; and a motor-fan unit being arranged downstream with respect to the air stream at the heat exchanger, the housing comprising a perforated structure with a plurality of openings delimited by ribs, and a skin secured to the perforated structure, covering the openings to form a wall impervious to the air stream.
