HEAT EXCHANGER FOR AIR COOLING

The present invention relates to a heat exchanger (1) configured to cool an air flow, comprising a heat core (2) comprising air flow channels (4) defining liquid passes (24, 26, 28, 30) in between at least two air flow channels (4), said heat core (2) comprising a group of central liquid passes (26) and two lateral liquid passes (28, 30), said heat core (2) comprising a plurality of plates (12, 14, 16, 18), at least one of the plates (12) having a plane portion and a projection defining a liquid chamber (36) in liquid communication with the liquid passes (24, 26, 28, 30), the liquid chamber (36) having a first section covering at least one of the lateral liquid passes (28, 30) which is bigger than a second section covering at least one of the central liquid passes (26).
