Abstract
A cooling system for a work vehicle includes first heat exchanger, a fan spaced apart from the first heat exchanger, a second heat exchanger extending between the fan and the first heat exchanger, and a third heat exchanger spaced apart from the second heat exchanger and extending between the fan and the first heat exchanger, A baffle plate is pivotally to a first position reducing air flow through the first heat exchanger and to a second position reducing air flow through the second heat exchanger. The baffle plate is pivoted by a linear actuator.

A cooling system for a work vehicle, comprising:
- a first heat exchanger having a first end and a second end positioned opposite from the first end;
- a fan spaced apart from the first heat exchanger;
- a second heat exchanger extending between the fan and the first end of the first heat exchanger;
- a third heat exchanger extending between the fan and the second end of the first heat exchanger, the fan and the first second and third heat exchangers enclosing a space having a generally quadrilateral cross-section where the fan is opposite the first heat exchanger, and the second heat exchanger is opposite the third heat exchanger;
- a baffle plate pivotally mounted to the cooling system, the baffle plate having a pivot axis positioned adjacent to the first end of the first heat exchanger, the baffle plate extending into the space enclosed by the fan and the first, second and third heat exchangers;
- an actuator for pivoting the baffle plate about the pivot axis;
- wherein the fan pulls air into the space through the first, second and third heat exchangers creating a first air flow stream and a second air flow stream, and the baffle plate sits between the first and second air flow streams such that the first air flow stream comes into the space through the first heat exchanger then around the baffle plate and then out of the space through the fan and the second air flow stream comes into the space through the second heat exchanger then around the baffle plate and then out of the space through the fan;
- wherein the second heat exchanger has a first end and a second end, and the third heat exchanger has a first end and a second end;
- the first ends of the second and third heat exchangers being located adjacent to the first heat exchanger and the second ends of the second and third heat exchangers being located adjacent to the fan;
- and
- wherein the distance between the first ends of the second and third heat exchangers is less than the distance between the second ends of the second and third heat exchangers.
