Abstract

A debris passage for a cooling box of a work vehicle. Airflow is provided into the cooling box from the exterior environment. A plurality of heat exchangers transfer heat into the airflow. The debris passage is defined between opposing heat exchangers to permit debris to pass from the airflow to the exterior of the cooling box. In one embodiment, the debris passage is underneath an air mover and is substantially vertical.

Claims

1. A cooling system comprising:

airflow into said cooling system from an exterior environment;

a plurality of heat exchangers for transferring heat into said airflow; and

a debris passage defined between at least a pair of said heat exchangers opposing one another for passing debris from said airflow to the exterior of said cooling system.

2. The cooling system of claim 1 wherein said debris passage permits debris from said airflow to fall between said opposing heat exchangers to the exterior of said cooling system.

3. The cooling system of claim 1 wherein said debris passage is substantially vertical.

4. The cooling system of claim 1 wherein said debris passage is underneath an air mover providing said airflow.

5. The cooling system of claim 1 wherein opposing ones of said heat exchangers converge in said airflow to define a debris outlet therebetween.

6. The cooling system of claim 5 wherein said heat exchangers define a cooling box and said debris outlet is below an air mover providing said airflow.

7. The cooling system of claim 6 further comprising an air mover for providing said airflow when moving in a first direction, said air mover when reversed into a second direction moving debris within said cooling box, and debris passing from said cooling box when said air mover is again operated in said first direction.

8. The cooling system of claim 5 wherein debris falls though said cooling box and said debris outlet due to gravity.

9. The cooling system of claim 5 wherein gravity affects debris falling from said air mover through said debris passage within said cooling box and out said debris outlet.

10. The cooling system of claim 5 wherein said airflow has a greater velocity through said debris outlet compared to said airflow through said heat exchangers to facilitate passing debris from said cooling box.

11. The cooling system of claim 1 further comprising an air mover for providing said airflow, said cooling system otherwise free of a cleaning assembly for cleaning debris from said air mover.
