Abstract

The invention concerns an intake housing 1 for an internal combustion engine, capable of receiving a heat exchanger for exchanging heat between a feed gas stream circulating in the housing and a coolant, wherein said intake housing 1 includes a space 3 for the circulation of the feed gas and a space 2 for receiving the heat exchanger, said receiving space 2 being defined by at least a first metal component 4, 5 including at least one extension 16, 17 that is in one piece with the first metal component 4, 5 , said extension 16, 17 at least partially defining the space 3 for the circulation of the feed gas.

First claim

The invention claimed is:

1. An intake housing ( 1 ) for an internal combustion engine, capable of receiving a heat exchanger ( 31 ) for exchanging heat between a feed gas stream circulating in the housing and a coolant, wherein said intake housing ( 1 ) includes a feed gas circulation space ( 3 ) for the circulation of the feed gas and a receiving space ( 2 ) receiving the heat exchanger ( 31 ), said receiving space ( 2 ) being defined by at least a first metal component ( 4 , 5 ) including at least one extension ( 16 , 17 ) that is in one piece with the first metal component ( 4 , 5 ), said extension ( 16 , 17 ) at least partially defining the feed gas circulation space ( 3 ) for the circulation of the feed gas, wherein the extension ( 16 , 17 ) includes at least one mechanical reinforcement ( 28 ) and wherein the mechanical reinforcement ( 28 ) takes the form of multiple deformations ( 29 ) produced by deformation of a portion of the first metal component ( 4 , 5 ) constituting said extension ( 16 , 17 ), wherein the mechanical reinforcement ( 28 ) is limited only to said extension ( 16 , 17 ) and is in the form of one or more ribs, and wherein one of the extension ( 16 ) lies in a plane coinciding with a plane in which one of the first metal component ( 4 ) lies and wherein another of the extension ( 17 ) lies in a plane coinciding with a plane in which another of the first metal component ( 5 ) lies, and wherein the plane in which said one of the first metal component ( 4 ) lies is parallel to the plane in which said another of the first metal component ( 5 ) lies.

2. The intake housing as claimed in claim 1 , wherein the first metal component ( 4 , 5 ) is a plate consisting at least in part of aluminum and produced by pressing.

3. The intake housing as claimed in claim 1 , wherein the receiving space ( 2 ) is delimited by a second metal component ( 5 ) that includes an extension ( 17 ) in one piece with the second metal component ( 5 ), said extension ( 7 ) delimiting the feed gas circulation space ( 3 ) on the side opposite the first metal component ( 4 ) relative to the heat exchanger ( 31 ).

4. The intake housing as claimed in claim 3 , including a lid ( 32 ) that extends between the first metal component ( 4 ) and the second metal component ( 5 ) to delimit the feed gas circulation space ( 3 ).

5. The intake housing as claimed in claim 1 , wherein the first metal component ( 4 ) is fastened to the heat exchanger ( 31 ).

6. The intake housing as claimed in claim 5 , wherein the first metal component ( 4 ) is an end plate forming part of the heat exchanger ( 31 ).

7. The intake housing as claimed in claim 3 , wherein the feed gas circulation space ( 3 ) includes an intake orifice ( 37 ) for said gas, said extension ( 16 , 17 ) being for the most part on the same side as the intake orifice ( 37 ).

8. An air intake module ( 30 ) of an internal combustion engine, including an intake housing ( 1 ) as claimed in claim 1 and a heat exchanger ( 31 ) in said intake housing ( 1 ).

9. The intake housing as claimed in claim 2 , wherein the receiving space ( 2 ) is delimited by a second metal component ( 5 ) that includes an extension ( 17 ) in one piece with the second metal component ( 5 ), said extension ( 7 ) delimiting the feed gas circulation space ( 3 ) on the side opposite the first metal component ( 4 ) relative to the heat exchanger ( 31 ).

10. An air intake module ( 30 ) of an internal combustion engine, including an intake housing ( 1 ) as claimed in claim 2 and a heat exchanger ( 31 ) in said intake housing ( 1 ).
