The device has one circulating-system branch respectively for the charge air cooling, the engine cooling and the coolant recooling. Using a change-over device, the circulating-system branches are connected to form a common coolant circulating system. The change-over device can be controlled as a function of the coolant temperature and the charge air pressure and, according to the respective operating requirement, controls the coolant throughput in the circulating-system branches.
