Heat transfer airflow through engine compartment
First Claim
1. A system for directing airflow through an engine compartment of an off-road agricultural vehicle, the system comprising:
- an engine compartment;
an engine arranged in the engine compartment delivering power for use by the off-road agricultural vehicle;
a radiator arranged in the engine compartment and configured to draw cooling air into an intake side of the radiator for transferring heat from the radiator to the cooling air converting the cooling air to heated air released from an discharge side of the radiator facing toward the engine;
a radiator discharge chamber defined by a space between the engine and the discharge side of the radiator configured to receive the heated air released from the discharge side of the radiator;
an air dam extending between the radiator and the engine, wherein the air dam defines an upper boundary of the radiator discharge chamber and is configured to vertically contain the heated air below the air darn and block flow of the heated air across an upper portion of the engine; and
a hood with interconnected walls defining an enclosure of the engine compartment, wherein the interconnected walls of the hood include a pair of side walls with air discharges extending through the side walls.

Abstract
A system is provided for directing airflow through an engine compartment of an off-road agricultural vehicle. The system may include an air dam that, in conjunction with an engine face, provides flow-directing baffling in the engine compartment that directs heated air from a radiator out discharge openings through side walls of a hood that covers the engine compartment. The air dam facilitates forcing heated air from the radiator sideways out the discharge openings of the hood, significantly reducing or preventing a radiator fan from pushing hot air to flow across the components of the rear engine compartment area, including preventing flow across a majority of air inlet components and engine surfaces that are rearward of the front engine face.

12. A self-propelled off-road agricultural vehicle comprising:
-
a chassis having wheels for moving the self-propelled off-road agricultural vehicle; a cab supported by the chassis; an engine compartment; an engine arranged in the engine compartment delivering power for use by the off-road agricultural vehicle; a radiator arranged in the engine compartment and configured to draw cooling air into an intake side of the radiator for transferring heat from the radiator to the cooling air converting the cooling air to heated air released from an discharge side of the radiator facing toward the engine; a radiator discharge chamber defined by a space between the engine and the discharge side of the radiator configured to receive the heated air released from the discharge side of the radiator; an air dam extending between the radiator and the engine, wherein the air dam defines an upper boundary of the radiator discharge chamber and is configured to vertically contain the heated air below the air dam and block flow of the heated air across an upper portion of the engine; and a hood with interconnected walls defining an enclosure of the engine compartment, wherein the interconnected walls of the hood include a pair of side walls with air discharges extending through the side walls. - View Dependent Claims (13, 14, 15, 16, 17, 18)
