The heat exchanger comprises a first housing (10) provided with air channels (210) extending in a first direction (X) from an upstream end wall (13) towards a downstream end wall (14), a top plenum (20) in an upper portion of the first housing (10) above the air channels (210), and partition walls (220, 230) extending in a second direction (Y) perpendicular to the first direction (X) and dividing a lower portion of the first housing (10) into an upstream end section (31), a middle section (32), and a downstream end section (33). The air channels (210) terminate at the partition wall (230) between the middle section (32) and the downstream end section (33). The downstream end section (33) comprises at least one cone (300) extending in the first direction (X) and having a first upstream end (301) at the partition wall (230) where the air channels (210) terminate, and a second contracted downstream end (302). |
