Abstract

A radiator arrangement for a motor vehicle has air inlet openings in the front of the arrangement and lateral air discharge openings. The arrangement is composed of an air guiding housing which has two separated spaces for receiving the water radiator and the oil radiator respectively. Separate air inlet ducts are provided for the spaces and a combined air guiding duct combines the air flows downstream of the radiators. The air is then discharged through lateral discharge openings in the side walls of the vehicle located ahead of the front wheels.

Claims

1. A radiator arrangement for the front of a motor vehicle, comprising:

an air guiding housing means adjacent an engine compartment with a first duct means and a second duct means,

a first radiator disposed in said first duct means,

a second radiator disposed in said second duct means,

a discharge opening for discharging air from said air guiding housing means laterally out of said vehicle,

separate inlet ducts located in front of said radiators and respectively connected to said first and second duct means, and separately communicating said first and second duct means with the front of said motor vehicle,

common air-guiding duct means located behind said radiators and connected to said discharge opening for combining air flowing through both said radiators and out said discharge opening, such that said air flowing through said radiators is directed towards said discharge opening;

further comprising ventilators situated in said common air-guiding duct means only behind said first radiator whereby a forced air flow is induced only through said first radiator.

2. A radiator arrangement for the front of a motor vehicle, comprising:

an air guiding housing means adjacent an engine compartment with a first duct means and a second duct means,

a first radiator disposed in said first duct means,

a second radiator disposed in said second duct means,

a discharge opening for discharging air from said air guiding housing means laterally out of said vehicle,

separate inlet ducts located in front of said radiators and respectively connected to said first and second duct means, and separately communicating said first and second duct means with the front of said motor vehicle;

common air-guiding duct means located behind said radiators and connected to said discharge opening for combining air flowing through both said radiators and out said discharge opening, such that said air flowing through said radiators is directed towards said discharge opening;

wherein said first duct means extends from both sides of a longitudinal central plane of said vehicle, and wherein said second duct means is bounded by said first duct means and a side wall of said vehicle; and

further comprising ventilators situated in said common air-guiding duct means only behind said first radiator whereby a forced air flow is induced only through said first radiator.

3. An arrangement according to claim 2, wherein said air guiding housing means is substantially enclosed and separate from the engine of said vehicle.

4. An arrangement according to claim 2, wherein two said air discharge openings are provided in the left and right side walls respectively, of said vehicle forward of a front wheel of said vehicle.

5. An arrangement according to claim 4, wherein said air discharge openings are configured such that the flow of air through said air discharge openings is uniform.

6. An arrangement according to claim 2, wherein said air inlet, and said air discharge openings are in approximately the same horizontal plane.

7. An arrangement according to claim 2, wherein said second radiator and said first radiator are connected to the engine oil and water cooling circuits respectively.

9. An arrangement according to claim 2, further comprising third duct means in said air-guiding housing means, a third radiator disposed in said third duct means in said substantially common plane with said first and second radiators, a second discharge opening for discharging air from said air-guiding housing means laterally out of said vehicle, a further separate inlet duct located in front of said third radiator and connected to said third duct means, wherein said common air-guiding duct means is located behind said third radiator and is connected to said additional discharge opening for combining air flowing through said radiators and out said additional discharge opening.

8. A radiator arrangement for the front of a motor vehicle, comprising:

an air guiding housing means adjacent an engine compartment with a first duct means and a second duct means,

a first radiator disposed in said first duct means,

a second radiator disposed in said second duct means,

a discharge opening for discharging air from said air guiding housing means laterally out of said vehicle,

separate inlet ducts located in front of said radiators and respectively connected to said first and second duct means, and separately communicating said first and second duct means with the front of said motor vehicle;

common air-guiding duct means located behind said radiators and connected to said discharge opening for combining air flowing through both said radiators and out said discharge opening, such that said air flowing through said radiators is directed towards said discharge opening;

further comprising third duct means in said air-guiding housing means, a third radiator disposed in said third duct means, a second discharge opening for discharging air from said air-guiding housing means laterally out of said vehicle, a further separate inlet duct located in front of said third radiator and connected to said third duct means, wherein said common air-guiding duct means is located behind said third radiator and is connected to said additional discharge opening for combining air flowing through said radiators and out said additional discharge openings; and

further comprising ventilators situated in said common air-guiding duct means only behind said first radiator whereby a forced air flow is induced only through said first radiator.

10. An arrangement according to claim 8, wherein said air guiding housing means is substantially enclosed and separate from the engine of said vehicle.

11. An arrangement according to claim 8, wherein said air discharge openings are provided in the left and right side walls respectively, of said vehicle forward of a front wheel of said vehicle.

12. An arrangement according to claim 11, wherein said air discharge openings are configured such that the flow of air through said air discharge openings is uniform.

13. An arrangement according to claim 8, wherein said air inlet and said air discharge openings are in approximately the same horizontal plane.

14. An arrangement according to claim 8, wherein said second radiator and said first radiator are connected to the engine oil and water cooling circuits respectively.
