Abstract

The device (12) according to the invention is suitable for cooling the air charging system (1) of a heat engine (2), said air charging system comprising a thermal turbocharger (10) and an electric supercharger capable of water cooling ( 11). The device comprises a first cooling circuit (12A) for cooling the charge air supplied by the system to the heat engine and a second cooling circuit (12B) for water cooling the electric supercharger. According to the invention, said device comprises a water-air heat exchanger (120) shared by said two cooling circuits.

Description

technical field [0001] The present invention relates generally to the field of motor vehicles. More particularly, the invention relates to a cooling device for an air charging system of a heat engine, including a thermal turbocharger and an electric supercharger. The invention also relates to an air charging system in which the cooling device is integrated. Background technique [0002] in reducing CO from motor vehicles 2 In the context of emissions, motor vehicle manufacturers have turned to the development of heat engines with fewer cylinders equipped with a new generation of air charging systems with higher performance and faster response. These next-generation air boosting systems are built around thermal turbochargers and electric superchargers. [0003] Conventional thermal turbochargers operating on energy recovered in the hot exhaust gases of a heat engine require sufficient pressure of the exhaust gases to operate the thermal turbocharger. In fact, the thermal ...
