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.

The invention claimed is: 1. A device for regulating the temperature of intake air for a motor vehicle internal combustion engine, the device comprising a first heat exchanger for exchanging heat between the intake air and a first heat-transfer fluid of a first circuit, and a second heat exchanger
The invention claimed is: 1. A device for regulating the temperature of intake air for a motor vehicle internal combustion engine, the device comprising a first heat exchanger for exchanging heat between the intake air and a first heat-transfer fluid of a first circuit, and a second heat exchanger for exchanging heat between the intake air and a second heat-transfer fluid of a second circuit, where the second heat-transfer fluid is colder than the first heat-transfer fluid and a third heat exchanger is connected in parallel with the first heat exchanger and the third heat exchanger exchanges heat between at least some exhaust gas from the internal combustion engine and the first heat-transfer fluid. 2. The device of claim 1, wherein the first circuit comprises a heat exchanger located on a front face of the motor vehicle so that the first heat-transfer fluid exchanges heat with air. 3. The device of claim 1, wherein a first pump circulates the first heat-transfer fluid in the first circuit. 4. The device of claim 1, wherein the first and second heat-transfer fluids comprise a liquid. 5. The device of claim 1, wherein the heat-transfer fluids circulating both in the second heat exchanger for exchanging heat between the intake air and the heat-transfer fluid and in the colder heat-transfer fluid are selected from the group consisting of carbon-dioxide and freon. 6. The device of claim 1, wherein, wherein the second heat-transfer fluid is thermally coupled to a cold source of a heat pump. 7. The device of claim 1, wherein a module comprises both the first and second heat exchangers. 8. The device of claim 1, wherein a module includes the first, second and third heat exchangers. 9. The device of claim 1, wherein a connection connects the first heat exchanger to a third circuit for a third heat-exchange fluid that is hotter than the first heat-exchange fluid, the connection includes a selector for selecting the first or third heat-exchange fluids for use in the first heat exchanger. 10. The device of claim 9, wherein the third circuit is connected to a cooling circuit of the internal combustion engine. 11. The device of claim 9, wherein the third circuit is thermally coupled to a hot source of a heat pump. 12. The device of claim 9, wherein the selector includes a selector valve comprising a first port, a second port and a third port, the first port comprising an inlet for heat-transfer fluid connected to the first heat-transfer circuit, the second port comprising an inlet for heat-transfer fluid connected to the third heat-transfer circuit, and the third port comprising an outlet for heat-transfer fluid connected to the first heat exchanger. 13. The device of claim 12, wherein a duct connects the third port of the selector valve both to the heat-transfer fluid inlet of the first heat exchanger and to the heat-transfer fluid inlet of the third heat exchanger. 14. The device of claim 13, wherein the selector include a valve for controlling flow rate of heat-transfer fluid through the third heat exchanger, the valve connecting the duct to the heat-transfer fluid inlet of the third heat exchanger. 15. The device of claim 1, wherein a turbo-compressor comprising a turbine driven by exhaust gas from the internal combustion engine maintains intake air at a pressure higher than atmospheric pressure in both the first and second heat exchangers. 16. The device of claim 1, wherein the internal combustion engine includes an exhaust system provided with a particle filter. 17. The device of claim 1, wherein the heat-transfer fluid comprises a mixture of water and antifreeze. 18. The device of claim 1, wherein intake air has a flow direction towards an air intake, and the second heat exchanger is downstream of the first heat exchanger relative to the flow direction.
