    Abstract: The invention relates to a heat exchanger comprising: at least one row of tubes (2), at least one fin (4) disposed transversely to said row of tubes (2), the tubes being connected to the fin (4) by clamping the tubes (2) in a collar (6) formed in the fin (4); and at least one row (10) of louvers (12), said row (10) being formed in the fin (4) and interposed between two tubes (2) in the row of tubes. With the fin (4) having a flat rectangular overall shape, the ratio between the number of louvers (12) and the width of the fin (4) is between 0.73 and 1.13.

    Abstract: The invention relates to a heat exchange module (22) for a motor vehicle (10), comprising: —a housing (32), —at least a first heat exchanger (24) and a second heat exchanger (26) which are arranged in the housing (32), and —a ventilation device comprising at least a first tangential-flow turbomachine (30a) which is configured to move at least a first airflow (F1) intended to pass through the set of heat exchangers (24, 26), and which is arranged downstream of the set of heat exchangers (24, 26) in the direction of flow of the first airflow (F1). According to the invention, the ventilation device comprises at least a second tangential-flow turbomachine (30b) which is configured to move at least one second airflow intended to pass through the first heat exchanger (24), and which is arranged on one side of the housing (32) between the first and second heat exchangers (24, 26) downstream of the first heat exchanger (24) in the direction of flow of the second airflow.

    IPC: F28F13/12

    Abstract: A tube for a heat exchanger defining a fluid circulation channel is disclosed. The channel extends along a longitudinal direction and includes a first flat wall including at least one pair of disturbance elements. The pair of disturbance elements is formed by a first and second disturbance element. The first and second disturbance elements are formed by a local deformation of the first flat wall toward the inside of the tube. The first and second disturbance elements extend between a first base and a first crest and between a second base and a second crest respectively. The first crest has an elongate shape along a first straight line and the second crest has an elongate shape along a second straight line. The first straight line intersects the second crest. The first and second crests have the same length measured between the two free ends of the crests.

    Abstract: The invention relates to a heat exchanger comprising: at least one fin (4); at least one row of tubes (2), the tubes being connected to the fin (4) by clamping the tubes (2) in a collar (6) formed in the fin (4); and at least one row (10) of louvers (12), said row (10) being formed in the fin (4) and interposed between two tubes (2) in the row of tubes, each louver (12) comprising a blade (14) provided with a free edge (16) and a connecting edge (18) connecting the louver (12) to the fin (4). The connecting edge (18) of the blade (14) of at least the first louver (12) in the row (10) forms an upstream edge with respect to the air flow, the free edge (16) of the blade (14) forming the downstream edge.
