A screen assembly for a work vehicle, the screen assembly comprising:
- a screen defining a plurality of screen openings for receiving an airflow therethrough, the screen further defining a flap opening;
- a flap pivotally coupled to the screen at the flap opening, the flap being configured to be moved to a closed position when the airflow through the screen is in a first direction and to an opened position when the airflow through the screen is in a second direction, wherein the second direction is opposite the first direction,
A work vehicle, comprising:
- a hood enclosure extending between a forward end and an aft end;
- a front screen disposed at the forward end of the hood enclosure;
- a heat exchanger positioned behind the front screen;
- a fan configured to generate an airflow in both a first direction, wherein air is drawn into the hood enclosure through the front screen and flows through the heat exchanger, and a second direction, wherein air is directed through the heat exchanger and out of the hood enclosure through the front screen;
- and
- a flap movable relative to the front screen, the flap configured to be in a closed position when the airflow is directed in the first direction and an opened position when the airflow is directed in the second direction.
A work vehicle, comprising:
- a hood enclosure extending between a forward end and an aft end;
- a screen assembly coupled to the hood enclosure, the screen assembly including a screen defining a plurality of screen openings for receiving an airflow therethrough and a flap movable relative to the screen;
- and
- a fan configured to generate an airflow in both a first direction, wherein air is drawn into the hood enclosure through the screen and a second direction, wherein air is expelled from the hood enclosure through the screen,
- wherein the flap is configured to be in a closed position when the airflow is directed through the screen in the first direction and an opened position when the airflow is directed through the screen in the second direction.
