Abstract

The motor vehicle cooling system (10) contains a fan (12) with which at least one cooler (13) is associated. Provision is made for the fan (12) to be in the form of a centrifugal blower with an air guiding housing (18).

Claims

1. A cooling system for a motor vehicle having an internal combustion engine, comprising a fan and a first heat exchanger and a second heat exchanger, wherein the fan comprises a centrifugal blower with an air guiding housing, wherein the air guiding housing comprises spiral housing, wherein the centrifugal blower is placed frontally before the internal combustion engine and is drivable by the internal combustion engine and wherein the centrifugal blower is connected by a first exhaust duct to the first heat exchanger and by a second exhaust duct to the second heat exchanger, said first heat exchanger, said second heat exchanger being connected in parallel with the centrifugal blower.

2. A cooling system according to claim 1, wherein the first heat exchanger comprises a coolant radiator for the internal combustion engine coolant.

3. A cooling system according to claim 2, wherein the first heat exchanger is disposed at the discharge side of the centrifugal blower.

4. A cooling system according to claim 2, wherein the coolant radiator comprises a counterflow cooler, a crossflow cooler or a multiple-path cooler.

5. A cooling system according to claim 1, wherein the second heat exchanger comprises a charging air cooler.

6. A cooling system according to claim 5, wherein the charging air cooler comprises a counterflow cooler.

7. A cooling system according to claim 5, wherein the charging air cooler comprises a multiple-path cooler.

8. A cooling system according to claim 5, wherein the charging air cooler is connected at its charging air inlet side by means of a charging air duct to a charging air turbocharger and at its charging air discharge side to the internal combustion engine by means of a charging air duct.

9. A cooling system according to claim 1, wherein the first heat exchanger comprises an oil cooler.

10. A cooling system according to claim 1, wherein the second heat exchanger comprises a condenser of an air conditioning system.

11. A cooling system according to claim 1, wherein the first heat exchanger is placed laterally or above or below the internal combustion engine.

12. A cooling system according to claim 1, wherein the first heat exchanger comprises a coolant radiator and the second heat exchanger comprises a charging air cooler connected parallel to one another on the discharge side of the centrifugal blower.

13. A cooling system according to claim 12, wherein the coolant for cooling charging air in the charging air cooler and used for cooling the internal combustion engine coolant provided by the coolant radiator comprises cooling air.

14. A cooling system according to claim 13, further comprising cooling air ducts for exhausting cooling air provided on the cooling air exhaust side of the coolant radiator and/or on the cooling air cooler.

15. A cooling system according to claim 1, wherein the first heat exchanger comprises a coolant radiator, and the coolant radiator and a charging air cooler are placed each on one side of the internal combustion engine, and the centrifugal blower is connected by the first exhaust duct to the coolant radiator and by the second exhaust duct to the charging air cooler, respectively.

16. A cooling system according to claim 1, wherein the centrifugal blower comprises a driving connection with the internal combustion engine.

17. A cooling system according to claim 1, wherein the internal combustion engine comprises a turbocharged diesel engine for a truck or a passenger car.

18. A motor vehicle with a cooling system, wherein the cooling system comprises a cooling system as defined by claim 1.

19. A cooling system for a motor vehicle having an internal combustion engine, comprising a fan and at least one cooler associated with the fan, wherein the fan comprises a centrifugal blower with an air guiding housing, wherein the air guiding housing comprises a spiral housing, wherein the centrifugal blower is placed frontally before the internal combustion engine and is drivable by the internal combustion engine, wherein the centrifugal blower is connected by an exhaust duct to the at least one cooler and wherein the cooling system comprises at least two coolers connected in series with one another with the interposition of the centrifugal blower.
