Claim:
1. A cooling device for a motor vehicle engine exhaust gas recirculation circuit, said circuit comprising a valve for controlling the circulation of said gas, said cooling device comprising: an EGR heat exchanger configured to allow an exchange of heat between exhaust gases received directly from the motor vehicle engine, passing through said recirculation circuit and a cooling fluid; means for cooling said valve; a high-temperature cooling loop configured so that said valve cooling means have a first fluid passing through; and a low-temperature cooling loop comprising an intercooler, the EGR exchanger, and a low-temperature radiator mounted in series in a direction of fluid flow in the low-temperature cooling loop, wherein the low-temperature cooling loop is configured so that a second fluid, at a temperature lower than that of the first fluid, passes through the EGR heat exchanger.
