Device for thermally controlling the intake air of the internal combustion engine of a motor vehicle

摘要

The device comprises a first heat exchanger ( 22 ) for exchanging heat between the admission air and a heat-transfer liquid for regulating the temperature of the admission air, the heat exchanger being connected to a circuit ( 24 ) for cold heat-transfer liquid, the device further comprising a second heat exchanger ( 26 ) for exchanging heat between the admission air and a heat-transfer fluid likewise for regulating the temperature of the admission air and connected to a circuit ( 28 ) for very cold heat-transfer fluid that is colder than the heat transfer liquid of the cold heat-transfer liquid circuit ( 24 ). The cold heat-transfer liquid circuit ( 24 ) preferably comprises a heat exchanger ( 30 ) for exchanging heat between air and the cold heat-transfer liquid, e.g. carried by a front face ( 31 ) of the motor vehicle.
