Abstract

The present invention concerns a cooling assembly (100) for a motor vehicle, comprising at least one first heat exchanger (110) extending mainly in a first plane (PI), at least one second heat exchanger (120) extending mainly in a second plan (P2) and at least one protective grid (136) for protecting the second heat exchanger (120), the first heat exchanger (110) and/or the second heat exchanger (120) being carried by a frame (130), characterised in that the at least one protective grid (136) of the second heat exchanger (120) forms a one-piece part with the frame (130).

First claim

The invention claimed is:

1. A cooling assembly for a motor vehicle, comprising:
at least one first heat exchanger mainly extending in a first plane;
at least one second heat exchanger mainly extending in a second plane; and
at least one protective grid for protecting the second heat exchanger, the first heat exchanger and/or the second heat exchanger being supported by a frame,
wherein the at least one protective grid for protecting the second heat exchanger is disposed between the first heat exchanger and the second heat exchanger, and forms a one-piece part with the frame, and
wherein the frame comprises at least one central zone that extends in a third plane parallel to the first plane of main extension of the first heat exchanger and to the second plane of main extension of the second heat exchanger, with the protective grid for protecting the second heat exchanger forming part of this central zone.

2. The cooling assembly as claimed in claim 1 , wherein the first heat exchanger and the second heat exchanger are both passed through by the same air flow, the first heat exchanger being arranged upstream of the second heat exchanger relative to a direction of circulation of this air flow, wherein at least one portion of the second heat exchanger extends beyond the first heat exchanger in the second plane of main extension of the second heat exchanger and wherein the protective grid for protecting the second heat exchanger extends opposite the portion of the second heat exchanger that extends beyond the first heat exchanger.

3. The cooling assembly as claimed in claim 2 , wherein the dimensions of the protective grid are at least identical to the dimensions of the portion of the second heat exchanger that extends beyond the first heat exchanger.

4. The cooling assembly as claimed in claim 2 , wherein at least the second heat exchanger comprises a heat exchange zone formed by a stack of tubes or of plates, with this heat exchange zone being configured to be passed through by the air flow and wherein the protective grid comprises a plurality of bars that each extend opposite one of these tubes or one of these plates of the heat exchange zone of the second heat exchanger.

5. The cooling assembly as claimed in claim 1 , comprising at least one means for protecting the first heat exchanger.

6. The cooling assembly as claimed in claim 1 , wherein the frame comprises at least one first attachment bracket configured to allow the first heat exchanger to be attached and comprises at least one second attachment bracket configured to allow the second heat exchanger to be attached, the at least one first attachment bracket and the at least one second attachment bracket being distributed on either side of the central zone of the frame.

7. The cooling assembly as claimed in claim 1 , wherein the central zone of the frame comprises at least two reinforcements, the first heat exchanger and the second heat exchanger both being arranged opposite these reinforcements.

8. The cooling assembly as claimed in claim 7 , wherein the protective grid for protecting the second heat exchanger, the frame and the two reinforcements form a one-piece assembly.

9. A motor vehicle comprising at least one front face and at least one cooling assembly as claimed in claim 1 , the cooling assembly being arranged in the front face of the vehicle.
