The invention relates to a circuit (NK) for cooling charge air (LL) in a motor vehicle comprising a turbocharger that is provided with a circulating pump () for the circuit (NK). Said pump () is coupled to a turbine () and forms a turbine/pump combination () along with the turbine ().

Circuit for cooling charge air, and method for operating such a circuit

The invention relates to a cooling circuit of an internal combustion engine of motor vehicles, comprising a main cooling circuit that encompasses a section located upstream of the radiator, a main radiator, a radiator return path, a coolant pump, a main thermostat, and a bypass or short circuit which is disposed between the main thermostat and the coolant pump. Said cooling circuit further comprises a low-temperature circuit encompassing a low-temperature radiator, a low-temperature radiator return path, a valve unit, and an additional heat exchanger.

Cooling circuit of an internal combustion engine comprising a low-temperature radiator

The invention relates to a circuit arrangement (K) comprising a low-temperature circuit (NK) for cooling charge air () that is fed to a motor () in a motor vehicle equipped with a turbocharger. According to the invention, the charge air () is compressed in two stages in a first low-pressure turbocharger () and a second high-pressure turbocharger (). To cool the charge air () a first cooler () is provided downstream of the low-pressure turbocharger () and upstream of the high-pressure turbocharger () and a second cooler () is provided downstream of the high-pressure turbocharger () and upstream of the motor (). The invention also relates to a method for operating a circuit arrangement (K) of this type.

Circuit arrangement for cooling charge air and method for operating a circuit arrangement of this type

The invention relates to a cooling module for an engine () of a motor vehicle. Said cooling module comprises a heat exchanger (), at least one fan () and a coolant pump (), whereby a modular frame () forms an integral part of the cooling module () and the coolant pump () is disposed within and/or on said modular frame.
