System for cooling at least one motor vehicle battery

The invention concerns a device () for controlling an air flow (F) circulating in a first heat exchanger () for a motor vehicle comprising at least two screens (), the control device () being configured to go from a closed configuration in which the screens () obstruct the passage of the air flow (F) completely to an open configuration in which the screens () are positioned in such a manner as to allow the air flow (F) to pass with a maximum flow rate, and any intermediate configuration. According to the invention, the two screens () are adapted to be moved away from one another when the control device () goes from the closed configuration to the open configuration and to be moved toward one another when the control device () goes from the open configuration to the closed configuration.

A heat exchanger () comprises an alternating stacking of first plates () and second plates () provided respectively with first corrugations () separated by a first pitch (P) and second corrugations () separated by a second pitch (P), which is different from the first pitch (P). Between the plates, first flow channels are defined having a first cross sectional area adapted to a first fluid (F) which alternate with second flow channels having a second cross sectional area adapted to a second fluid (F). The invention applies in particular to heat exchangers for motor vehicles.

A manifold distributes gases into intake ducts of a motor vehicle combustion engine. The intake ducts are distributed in at least two distant groups, each duct of one group supplying one and the same cylinder of the engine as a duct of the other group. The manifold includes a manifold casing through which a flow of intake gases can flow, and an injection duct for injecting a flow of recirculated exhaust gases into the flow of intake gases. The casing is capable of directing the flow of intake gases and the flow of recirculated exhaust gases toward the intake ducts of the engine, and the injection duct is arranged inside the manifold casing so as to be able to be positioned between the two groups of intake ducts.
