Abstract

This air distributor ( 1 ) has an exterior casing defining an interior volume, an air inlet ( 4 ) opening into this interior volume, several air outlets ( 4 ) intended to convey air from the interior volume towards the cylinders of an engine, and a heat exchanger ( 8 ) arranged in the interior volume. The heat exchanger ( 8 ) comprises a stack of plates ( 10 ) of plastic material where adjacent plates ( 10 ) are arranged so as to define a set of intermediate spaces comprising closed intermediate spaces ( 12 ) in fluid communication to enable circulation of fluid through the stack of plates ( 10 ), and open intermediate spaces ( 14 ) configured to enable a passage of air through the stack of plates ( 10 ) from the air inlet ( 4 ) to the air outlets ( 6 ).

First claim

The invention claimed is:

1. An air distributor having an outer enclosure delimiting an interior volume, an air inlet opening into this interior volume, and several air outlets intended to conduct air from the interior volume to cylinders of an engine, wherein the air distributor comprises a heat exchanger arranged in the interior volume, the heat exchanger comprising a stack of plates made of plastic material, wherein adjacent plates of the stack of plates are arranged so as to delimit a set of intermediate spaces, the set of intermediate spaces comprising closed intermediate spaces that are fluidically connected together to allow a circulation of fluid through the stack of plates, and open intermediate spaces that are configured to allow an air passage through the stack of plates from the air inlet to the air outlets of the distributor, wherein plates of the stack of plates have an edge secured to the outer enclosure of the distributor and the edge of the plates is continuously bonded to the outer enclosure of the distributor.

2. The air distributor according to claim 1 , wherein the outer enclosure of the distributor has a side wall, and a contour of the plates is similar to the contour delimited by the side wall.

3. The air distributor according to claim 2 , wherein the contour of the plates and of the side wall extends at least partly in a curvilinear manner.

4. The air distributor according to claim 1 , wherein the heat exchanger comprises a fluid intake aperture and a fluid discharge aperture each opening into one of the closed intermediate spaces in order to allow entry and exit of the fluid between the outside of the distributor and the closed intermediate spaces of the stack of plates, and these intake and discharge apertures are formed through the outer enclosure of the distributor.

5. The air distributor according to claim 1 , wherein the heat exchanger comprises a fluid intake and discharge channel in order to allow the circulation of a fluid through the closed intermediate spaces of the stack of plates, these intake and discharge channels being arranged opposite the air inlet of the distributor so as to divide air flow entering the open intermediate spaces.

6. The air distributor according to claim 1 , wherein the outer enclosure has a wall which is opposite a face of one of the plates of the heat exchanger and which delimits therewith an open or closed intermediate space.

7. The air distributor according to claim 1 , wherein plates of the stack of plates extend at least partly in a duct delimiting the air inlet and/or in one or more duct(s) delimiting the air outlets.

8. The air distributor according to claim 7 , wherein these plates have tabs extending from the edge of these plates to the duct delimiting the air inlet and/or one or more duct(s) delimiting the air outlets, the tabs comprising walls or ribs longitudinally extending along an axis of this or these duct(s).

9. The air distributor according to claim 1 , wherein several plates of the stack of plates have a different geometry.

10. The air distributor according to claim 1 , wherein the outer enclosure of the distributor is made of plastic material.

11. The air distributor according to claim 1 , wherein the outer enclosure of the distributor is made of a material distinct from that of plates of the stack of plates.

12. A vehicle comprising a distributor according to claim 1 .

13. The air distributor according to claim 1 , wherein the outer enclosure of the distributor has a side wall and a contour of the plates and of the side wall extends at least partly in a curvilinear manner.

14. The air distributor according to claim 13 , wherein the heat exchanger comprises a fluid intake aperture and a fluid discharge aperture each opening into one of the closed intermediate spaces in order to allow entry and exit of the fluid between the outside of the distributor and the closed intermediate spaces of the stack of plates, and these intake and discharge apertures are formed through the outer enclosure of the distributor.

15. The air distributor according to claim 14 , wherein the heat exchanger comprises a fluid intake and discharge channel in order to allow the circulation of a fluid through the closed intermediate spaces of the stack of plates, these intake and discharge channels being arranged opposite the air inlet of the distributor so as to divide air flow entering the open intermediate spaces.

16. The air distributor according to claim 15 , wherein the outer enclosure has a wall which is opposite a face of one of the plates of the heat exchanger and which delimits therewith an open or closed intermediate space.

17. The air distributor according to claim 16 , wherein plates of the stack of plates extend at least partly in a duct delimiting the air inlet and/or in one or more duct(s) delimiting the air outlets.
