System for cooling a gaseous intake fluid for an internal combustion engine, integrated into a cooling circuit of the engine

摘要

Cooling apparatus for a supercharged internal combustion engine (E), comprising a circuit provided with a pump (40) for circulating a cooling fluid between the internal combustion engine (E) and a cooling radiator (10) which exchanges heat with external atmospheric air; the cooling radiator has a main outlet (12) connected to a suction side of the pump. The apparatus further comprises a conduit (90) for cooling a gaseous intake fluid for the engine, the conduit comprising a low temperature radiator (91) which exchanges heat with external atmospheric air, and which is connected to a secondary outlet (92) of the cooling radiator, this outlet being different from the main outlet, and a cooler (80) which cools the gaseous intake fluid by means of a heat exchange with the cooling fluid, connected to an outlet of the low temperature radiator, an outlet of the cooler being connected to a suction side of the pump, downstream of the main outlet (12) of the cooling radiator (10).
