Abstract

A vehicle cooling system includes a fan, a radiator upstream of the fan and in a first air flow path, a charge air cooler upstream of the radiator in the first air flow path, a fuel cooler upstream of the radiator in the first air flow path, and a hydraulic oil cooler adjacent to a side of the radiator and upstream of the fan and in a second air flow path which is parallel to the first air flow path. A condenser is positioned in the first air flow path between the fuel cooler and the radiator. The hydraulic oil cooler has an upstream side which is unobscured by any other cooling system components. The hydraulic oil cooler includes first and second hydraulic oil cooler units connected together in series. A portion of the hydraulic oil cooler is positioned above a top side of the radiator.

First claim

What is claimed is:

1. A vehicle cooling system, comprising:
a fan;
a radiator upstream of the fan and in a first air flow path;
a fuel cooler upstream of the radiator in the first air flow path and adjacent to a side of a charge air cooler; and
a hydraulic oil cooler adjacent to a side of the radiator and upstream of the fan and in a second air flow path which is parallel to the first air flow path, the hydraulic oil cooler comprising first and second hydraulic oil cooler units connected together in series.

2. The cooling system of claim 1 , further comprising:
a condenser positioned in the first air flow path between the fuel cooler and the radiator.

3. The cooling system of claim 1 , further comprising:
a condenser positioned adjacent to a side of the charge air cooler between the radiator and the fuel cooler.

4. The cooling system of claim 1 , further comprising:
a condenser positioned below a bottom side of the charge air cooler and upstream of the radiator.

5. The cooling system of claim 1 , wherein:
the hydraulic oil cooler has an upstream side which is unobscured by any other cooling system components.

6. The cooling system of claim 1 , wherein:
a portion of the first hydraulic oil cooler unit is positioned above a top side of the charge air cooler, and the second hydraulic oil cooler unit is positioned above a top side of the radiator.

7. The cooling system of claim 1 , wherein:
at least a portion of the hydraulic oil cooler is positioned above a top side of the radiator.

8. The cooling system of claim 1 , wherein:
the hydraulic oil cooler is exposed to cooling air which has not previously passed through any other cooling unit.

9. The cooling system of claim 1 , further comprising:
a charge air cooler upstream of the radiator in the first air flow path.

10. A vehicle cooling system, comprising:
at least one fan;
a radiator upstream of the fan and in a first air flow path;
a plurality of cooler units upstream of the radiator in the first air flow path, the plurality of cooler units comprising at least two of a charge air cooler, a fuel cooler, or a condenser; and
a dual pass hydraulic oil cooler adjacent to a side of the radiator and upstream of the fan and in a second air flow path which is parallel to the first air flow path.

11. The cooling system of claim 10 ,
wherein the condenser is positioned in the first air flow path between the fuel cooler and the radiator.

12. The cooling system of claim 10 ,
wherein the condenser is positioned adjacent to a side of the charge air cooler between the radiator and the fuel cooler.
