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.
Claims10
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.
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.
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.
