Abstract: The invention concerns a device (12) for controlling an air flow (F) circulating in a first heat exchanger (4) for a motor vehicle comprising at least two screens (14), the control device (12) being configured to go from a closed configuration in which the screens (14) obstruct the passage of the air flow (F) completely to an open configuration in which the screens (14) 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 (14) are adapted to be moved away from one another when the control device (12) goes from the closed configuration to the open configuration and to be moved toward one another when the control device (12) goes from the open configuration to the closed configuration.

Abstract: The present invention relates to a header usable with an exchanger bundle of a heat exchanger. Said exchanger bundle includes at least one first row of tubes and one second row of tubes. The tubes are suitable for enabling the flow of a first fluid in the exchanger bundle. The header includes at least: —one first contact element for supporting the top side of a first end of the first row of tubes; —one second contact element for supporting the bottom side of said first end of the first row of tubes and supporting the top side of a first end of the second row of tubes, the thickness of the second contact element defining the distance between said first and second rows of tubes; and —one third contact element for supporting the bottom side of said first end of the second row of tubes.

Abstract: A heat exchanger (10) comprises an alternating stacking of first plates (12) and second plates (14) provided respectively with first corrugations (16) separated by a first pitch (P1) and second corrugations (18) separated by a second pitch (P2), which is different from the first pitch (P1). Between the plates, first flow channels are defined having a first cross sectional area adapted to a first fluid (F1) which alternate with second flow channels having a second cross sectional area adapted to a second fluid (F2). The invention applies in particular to heat exchangers for motor vehicles.
