Abstract: The invention relates to a device (1, 11) for cooling a coolant by heat exchange with another fluid, that comprises an inlet and at least two outlets (3, 4) provided at different levels for over-cooling the coolant. The device (1, 11) is characterised in that it comprises a modular structure including at least two modules (5, 6), each module (5, 6) including at least one outlet (3, 4), and in that both modules (5, 6) are hydraulically connected together by a male end-piece (7) of a first module interacting by insertion with a female end-piece (8) having a complementary shape of a second module (5).

Abstract: A heat exchanger including at least a first manifold and a second manifold connected by a bundle of horizontal tubes. An air flow circulates to be cooled by a cooling air flow. The bundle includes at least: a first portion including a first series of tubes with turbulators of passage section corresponding to the section; a second portion including a first series of tubes with no turbulators of passage section and a second series of tubes with turbulators of passage section corresponding to the section; and a distribution box of internal air flow to be cooled including a connection mechanism between the first portion and the second portion.
