Abstract: A heat exchanger comprises: a plurality of tubes for the circulation of a coolant which are arranged as a core bundle of tubes having a width in a longitudinal direction, a depth in a transverse direction, and a height in a vertical direction; a first header and a second header into which the tubes of the core bundle open; and a first partition arranged respectively in the first and second headers. The first partition respectively divides the first header and the second header, at least partially, into a first compartment and a second compartment which are adjacent in the transverse direction. The heat exchanger further comprises at least one second partition dividing the first compartment and the second compartment of the first header into a first chamber, a fourth chamber, and at least one return compartment which is adjacent, in the longitudinal direction, to the first and fourth chambers.
