1. A heat exchanger comprising:
a plurality of tubes arranged in a first and a second row and through which a refrigerant is intended to circulate;
a first and a second header tank inside which the plurality of tubes of each of the said rows emerge;
the first header tank comprising a refrigerant inlet compartment into which the tubes of the first row emerge and a refrigerant outlet compartment into which the tubes of the second row emerge,
the second header tank comprising at least one return compartment into which at least one tube of the first row and one tube of the second row emerge, and
the first header tank comprising a cover having an inlet portion and an outlet portion, the inlet portion having a semi-circular shape and the outlet portion having a flattened shape compared to the inlet portion, such that a height of the inlet portion is greater than a height of the outlet portion,
wherein the outlet compartment has a smaller volume than the inlet compartment.
