Abstract:
1. A heat exchanger for a supercharged internal combustion engine, comprising: at least one first manifold and one second manifold, which are connected in a transverse direction by a bundle of horizontal tubes that extend in said transverse direction and are positioned entirely between the first manifold and the second manifold, and an internal air flow circulates in the tube bundle to be cooled by a flow of cooling fluid circulating outside the tube bundle; wherein the tube bundle includes: a first part including a first series of tubes with turbulators having a first total passage section and a second series of tubes without turbulators having a second total passage section globally equivalent to the first total passage section, a second part including a first series of tubes without turbulators having a third total passage section and a second series of tubes with turbulators having a fourth total passage section globally equivalent to the third total passage section, and a box configured to distribute the internal flow of air to be cooled, including means for connecting an outlet of the first series of tubes with turbulators of the first part to an inlet of the first series of tubes without turbulators of the second part, and for connecting an outlet of the second series of tubes without turbulators of the first part to an inlet of the second series of tubes with turbulators of the second part, wherein the first series of tubes of the first part is entirely upstream in the transverse direction from the first series of tubes of the second part, and wherein the second series of tubes of the first part is entirely upstream in the transverse direction from the second series of tubes of the second part.
