Abstract
An engine cooling system includes a first heat exchanger receiving a first fluid and a second heat exchanger receiving a second fluid. The second heat exchanger is located adjacent the first heat exchanger, thereby creating a stacked heat exchanger. The engine cooling system also includes a third heat exchanger receiving a third fluid. The third heat exchanger is located apart from the stacked heat exchanger. A venturi is located between the stacked heat exchanger and the third heat exchanger. An air mover is mounted to the venturi and located within the venturi. The air mover is configured to move air through the stacked heat exchanger and through the third heat exchanger. In a specific embodiment, the engine cooling system is incorporated into a vehicle, such as a skidder vehicle.
Claims20
An engine cooling system comprising:
- a first heat exchanger receiving a first fluid;
- a second heat exchanger receiving a second fluid and located adjacent the first heat exchanger, creating, a stacked heat exchanger;
- a third heat exchanger receiving a third fluid and located apart from the stacked heat exchanger;
- a venturi located between the stacked heat exchanger and the third heat exchanger;
- and
- an air mover mounted to the venturi and located within the venturi, the air mover is configured to move air through the stacked heat exchanger and through the third heat exchanger.
A vehicle comprising
- a frame;
- an engine supported by the frame;
- a drive train configured to propel the machine using power from the engine;
- and
- an engine cooling system in fluid communication with the engine, the engine cooling system includes;
- a low ΔT heat exchanger;
- a high ΔT heat exchanger located apart the low ΔT heat exchanger;
- a venture located between the low ΔT heat exchanger and the high ΔT heat exchanger, the venturi is nested with a drive shaft portion of drive train;
- and
- an air mover located within the venturi, the air mover is configured to move air through the low ΔT heat exchanger and then through the high ΔT heat exchanger at a direction substantially normal to the drive shaft.
A skidder machine comprising;
- a frame;
- an engine supported by the frame;
- a drive train configured to propel the machine using power from the engine;
- a grapple system mounted to the frame, the grapple system is configured to clinch objects using power from the engine and to tow the objects as the machine is propelled;
- and
- an engine cooling system in fluid communication with the engine, the engine cooling system includes;
- a first heat exchanger receiving a first fluid;
- a second heat exchanger receiving a second fluid and located adjacent the first heat exchanger, creating a stacked heat exchanger;
- a third heat exchanger receiving a third fluid and located apart from the stacked heat exchanger;
- a venturi located between the stacked heat exchanger and the third heat exchanger;
- and
- an air mover mounted to the venturi and located within the venturi, the air mover is configured to move air through the stacked heat exchanger and through the third heat exchanger.
