Abstract

The invention relates to a device for adjusting ( 80 ) an air stream for an air inlet of a motor vehicle, comprising a housing ( 81 ) defining a flow duct ( 82 ) into which an air stream flows and in which a cooling unit comprising at least one heat exchanger ( 83 ) is at least partially arranged, the housing comprising a flap ( 85 ) designed to be placed in an open position providing access to the heat exchanger, said flap being designed to close the access in the closed position, said access ( 86 ) being designed in particular to enable removal of the heat exchanger through a substantially translational movement.

First claim

The invention claimed is:

1. A device for regulating an air stream for an air inlet of a motor vehicle, comprising:
a housing defining a flow duct in which there flows an air stream, in which a cooling unit comprising at least one heat exchanger is at least partially arranged,
the housing having a hatch arranged so as to be placed in an open position freeing up an access to the heat exchanger, the hatch being arranged so as to close the access in the closed position, wherein the hatch has a main face and two lateral walls that face each other, these lateral walls having a substantially triangular shape, the main wall being in two parts that are connected to each other, and
the access being arranged so as to allow removal of the heat exchanger via a substantially translational movement.

2. The device as claimed in claim 1 , wherein the hatch is connected to a fixed wall of the housing by an articulation arranged so as to allow the hatch to pivot between the closed position and the open position, a hinge extending along a line that is at a non-zero distance from two parallel edges of the housing.

3. The device as claimed in claim 2 , wherein the articulation has at least one hinge produced in one piece with at least one of the fixed wall and the hatch.

4. The device as claimed in claim 3 , wherein the hatch is connected to the fixed wall by at least two hinges by two identical hinges that are parallel to each other.

5. The device as claimed in claim 2 , in which the articulation between the hatch and the fixed wall has one or more hinge pins.

6. The device as claimed in claim 1 , wherein the hatch extends over a surface area at least 1.5 or 2 times greater than the surface area of the fixed wall, wherein the fixed wall is substantially flat and adjacent to the hatch.

7. The device as claimed in claim 1 , wherein the hatch is formed on an upstream part of the housing, the upstream part being placed upstream of the heat exchanger, this upstream part extending between an air inlet and the heat exchanger, the hatch being in the closed position, in sealed contact with a frame.

8. The regulating device as claimed in claim 1 , wherein the housing has two half-housings, which together form said flow duct, a means being arranged between each half-housing and a frame or between these half-housings.

9. A method for removing a heat exchanger from a device as claimed in claim 1 , said method comprising:
putting the hatch in the open position, thereby freeing up the access to the heat exchanger; and
removing, through said access, this heat exchanger, in particular via a substantially translational movement.
