  • the storage device By incorporating the storage device into the third coolant circuit, cold water can thus be quickly fed into the engine block and / or the cylinder head via the third coolant circuit in order to cool it effectively and rapidly.
  • This is particularly advantageous in high-load operation of the internal combustion engine, since this improves the high-load capability of the engine.
  • this configuration according to the invention is also very advantageous if the motor vehicle has a shutter located in front of the coolant radiator. Radiator shutters are used, for example, at low Outside temperatures or, if the engine has not yet reached its final operating temperature, to compensate for the effect of the radiator.
  • the use of Ktthlerjalousien is advantageous for improving the aerodynamics and thus to reduce fuel consumption.
  • the cooling performance of the coolant radiator is deteriorated because there is no longer sufficient airflow for cooling the coolant flowing through the radiator. Therefore, an additional cold water storage for cooling the engine block, which is achieved by the use of the storage device or their integration into the third refrigerant circuit is particularly advantageous in this case.
  • the configuration according to the invention advantageously makes it possible to realize a prolonged transit time in the operation of blinds.
  • a reduction in the thermal cycling of the coal cooler is achieved by the circuit arrangement according to the invention.
  • the first heat exchanger is a coolant radiator, in particular a high-temperature coolant radiator.
  • the first valve is an electrically, magnetically or electromagnetically actuatable valve, wherein the first valve preferably has a switching time of less than 2 s.
  • a first pump is arranged between the first valve and the storage device.
  • the function of the storage device as a heat storage and cold storage is changeable.
  • the storage device has an output which is ver connected to the heating device and a cylinder head of the Srenrtkraftmaschme via the second coolant circuit.
  • the output of the storage device is connected to the engine block via the third cooling circuit.
  • the output of the storage device is connected to an inlet of a second valve.
  • the second valve has a first outlet and a second outlet.
  • the first outlet of the second valve directs the coolant into the third coolant circuit to the engine block, and the second outlet of the second valve, the coolant in the zweten coolant circuit to the heater and / or the cylinder head passes.
  • the coolant coming from the storage device via the third coolant circuit when the storage device acts as a cold storage, can be fed into the engine block via a pump intake side.
  • an intake in the region of the exhaust gas cooler, an intake in the region of the turbocharger, an intake in the region of the engine oil cooler or in the region of the transmission oil cooler can be implemented.
  • a second heat exchanger in particular a low-temperature cooler, is provided in the circuit arrangement.
  • the storage device is charged with coming from the low-temperature cooler cold coolant, the high-temperature coolant radiator cools the engine block via the firstdemitteiniklauf.
  • the first heat exchanger is integrated into the first coolant circuit and the third coolant circuit.
  • the first heat exchanger may be integrated in the first coolant circuit and the second heat exchanger in the third coolant circuit.
  • the storage device is integrated in a refrigerant circuit of an automotive air conditioning system.
  • a capacitor can be integrated into the memory device.
  • a coolant consisting of a mixture of water and antifreeze circulates through the first heat exchanger 5, in which the coolant is cooled by wind during driving of the motor vehicle, via the thermostat 10 and the second pump 9 to the engine block 12 and the cylinder head 13, of which the heated by the engine block 12 and the cylinder head 13 then coolant is passed back to the first heat exchanger 5, where it is in turn cooled by the airstream.
