Abstract

In one aspect, an air intake system for supplying air to an engine of a work vehicle may include a cooler box having a first wall and a second wall, with the first and second walls at least partially defining a chamber within the cooler box. The air intake system may also include a screen defining at least a portion of the first wall of the cooler box. Furthermore, the air intake system may include an air filter assembly defining at least a portion of the second wall of the cooler box. The air filter assembly may be configured to remove particles present in the air exiting the chamber of the cooler box through the air filter assembly. The air exiting the cooler box through the air filter assembly may be supplied to the engine for combustion.

Claims

1. An air intake system for supplying air to an engine of a work vehicle, the air intake system comprising:

a cooler box including a first wall and a second wall, the first and second walls at least partially defining a chamber within the cooler box;

a screen defining at least a portion of the first wall of the cooler box, the screen being configured to remove particles present in air entering the chamber of the cooler box; and

an air filter assembly defining at least a portion of the second wall of the cooler box, the air filter assembly including an air filter element configured to remove particles present in the air exiting the chamber of the cooler box through the air filter assembly,

wherein the air exiting the cooler box through the air filter assembly is supplied to the engine for combustion.

2. The air intake system of claim 1, wherein the air filter assembly further comprises a pre-cleaner positioned upstream of the air filter element, the air intake system further comprising:

a vacuum source configured to generate a vacuum within the pre-cleaner to remove particles in the air flowing through the pre-cleaner.

3. The air intake system of claim 1, further comprising:

a pre-cleaner positioned upstream of the screen; and

a vacuum source configured to generate a vacuum within the pre-cleaner to remove particles that have accumulated on the screen.

4. The air intake system of claim 3, wherein the pre-cleaner comprises a wand configured to rotate relative to the screen to remove the particles that have accumulated on the screen.

5. The air intake system of claim 1, wherein the filter assembly comprises a first pre-cleaner positioned upstream of the air filter element, the air intake system further comprising:

a second pre-cleaner positioned upstream of the screen; and

a vacuum source configured to generate a vacuum within the first and second pre-cleaners.

7. The air intake system of claim 1, wherein the second wall is oriented perpendicular relative the first wall.

8. The air intake system of claim 1, wherein the cooler box extends vertically between a top wall and a bottom wall, the second wall corresponding to the top wall of the cooler box.

9. The air intake system of claim 1, wherein the chamber of the cooler box is configured to house one or more heat exchangers.

19. The air intake system of claim 1, wherein the first wall and the second wall are directly coupled together.

6. (canceled)

10. A work vehicle, comprising:

an engine;

a cooler box including a first wall and a second wall, the first and second walls defining a chamber of the cooler box;

a screen defining at least a portion of the first wall of the cooler box, the screen being configured to remove particles present in air entering the chamber of the cooler box;

an air filter assembly defining at least a portion of the second wall of the cooler box, the air filter assembly including an air filter element configured to remove particles present in the air exiting the chamber of the cooler box through the air filter assembly; and

air conduit extending between the air filter assembly and the engine, the air conduit being configured to supply air from the air filter assembly to the engine for combustion.

11. The work vehicle of claim 10, wherein the air filter assembly further comprises a pre-cleaner positioned upstream of the air filter element, the work vehicle further comprising:

a pre-cleaner positioned upstream of the screen; and

a vacuum source configured to generate a vacuum within the pre-cleaner to remove particles that has accumulated on the screen.

13. The work vehicle of claim 12, wherein the pre-cleaner comprises a wand configured to rotate relative to the screen to remove the particles that has accumulated on the screen.

14. The work vehicle of claim 10, wherein the air filter assembly comprises a first pre-cleaner positioned upstream of the air filter element, the work vehicle further comprising:

a second pre-cleaner positioned upstream of the screen; and

a vacuum source configured to generate a vacuum within the first and second pre-cleaners.

15. The work vehicle of claim 10, further comprising:

a secondary air filter positioned within the air conduit downstream of the air filter assembly and spaced apart from the cooler box, the secondary air filter being configured to remove particles present in the air flowing through the secondary air filter.

16. The work vehicle of claim 10, wherein the second wall is oriented perpendicular relative the first wall.

17. The work vehicle of claim 10, wherein the cooler box extends vertically between a top wall and a bottom wall, the second wall corresponding to the top wall of the cooler box.

18. The work vehicle of claim 10, further comprising:

one or more heat exchangers positioned within the cooler box, the one or more heat exchangers being configured to cool one or more fluids circulated through the engine.

20. The work vehicle of claim 10, wherein the first wall and the second wall are directly coupled together.

21. An air intake system for supplying air to an engine of a work vehicle, air intake system comprising:

a cooler box including a first wall and a second wall, the first and second walls at least partially defining a chamber within the cooler box;

a screen defining at least a portion of the first wall of the cooler box, the screen being configured to remove particles present in air entering the chamber of the cooler box;

an air filter assembly defining at least a portion of the second wall of the cooler box, the air filter assembly including an air filter element configured to remove particles present in the air exiting the chamber of the cooler box through the air filter assembly; and

a secondary air filter positioned downstream of the air filter assembly and spaced apart from the cooler box, the secondary air filter being configured to remove particles present in the air flowing through the secondary air filter,
