HEAT EXCHANGER FOR A MOTOR VEHICLE

摘要

The invention relates to a heat exchanger (1), including: a plurality of tubes (5) enabling a cooling fluid to circulate, wherein said tubes are arranged in the form of a tube bundle (3) having a width (I) in a longitudinal direction (x), a depth (p) in a transverse direction (y), and a height (h) in a vertical direction (z); a first collecting box (9, 87) and a second collecting box (11, 89) into which the tubes (5) of the tube array (3) lead; a first partition (27, 103, 116) arranged in the first collecting box (9, 87) and in the second collecting box (11, 89), respectively, the first partition (27, 103, 116) at least partially dividing the first collecting box (9, 87) and the second collecting box (11, 89), respectively, into a first compartment (28) and second compartment (29) that are adjacent in the transverse direction. The heat exchanger (1) includes at least one second partition (30, 105, 109) dividing the first compartment (28) and the second compartment (29) of the first collecting box (9, 87) into a first chamber (31, 117), a fourth chamber (37, 118), and at least one turn-over compartment (33, 35; 111) that is adjacent to the first chamber (31, 117) and to the fourth chamber (37, 118) in the longitudinal direction.
