Heat exchanger for air cooling

A heat exchanger configured to cool an air flow with a coolant liquid, the heat exchanger comprising:

• a heat exchanger core,
• a first air flow duct located at a first longitudinal end of the heat exchanger core, and
• a second air flow duct located at a second longitudinal end of the heat exchanger core,
• the heat exchanger core comprising a plurality of air flow channels defining liquid passes in between at least two air flow channels,
• the heat exchanger core comprising a plurality of plates enveloping the air flow channels and the liquid passes,
• wherein at least one of the plates comprises at least a first projection defining a liquid chamber at the first longitudinal end of the heat exchanger core and at least a second projection defining a corridor connected to the liquid chamber and configured for the circulation of the coolant liquid,
• wherein the corridor extends from the liquid chamber and in the direction of the second longitudinal end of the heat exchanger core.
