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.

Abstract: A vehicle cooling system includes a fan, a radiator upstream of the fan and in a first air flow path, a charge air cooler upstream of the radiator in the first air flow path, a fuel cooler upstream of the radiator in the first air flow path, and a hydraulic oil cooler adjacent to a side of the radiator and upstream of the fan and in a second air flow path which is parallel to the first air flow path. A condenser is positioned in the first air flow path between the fuel cooler and the radiator. The hydraulic oil cooler has an upstream side which is unobscured by any other cooling system components. The hydraulic oil cooler includes first and second hydraulic oil cooler units connected together in series. A portion of the hydraulic oil cooler is positioned above a top side of the radiator.

Abstract: A vehicle cooling system includes a fan, a first heat exchanger, an upper heat exchanger and a lower heat exchanger. The first heat exchanger is spaced apart in front of the fan. The upper heat exchanger is positioned between a top portion of the fan and a top portion of the first heat exchanger. The lower heat exchanger is positioned between a bottom portion of the fan and a bottom portion of the first heat exchanger. A structural frame supports the first, top and lower heat exchangers, and the frame forming a fan shroud which surrounds the fan.

Abstract: An axial flow fan assembly includes a plurality of fan blades surrounded by a shroud. The shroud includes an annular first wall which extends radially outwardly, an annular second wall which extends axially and radially outwardly, and an annular third wall which joins the first wall to the second wall. The third wall has a curved cross sectional shape, and has a minimum diameter part which is positioned approximately half-way between the upstream and downstream edges of the fan blades. There is a desired relationship between the radius of curvature of the third wall and the diameter of the fan. There is a desired relationship between the height of the first wall and the diameter of the fan. The fan blades have an upstream edge which is upstream with respect to the first wall.
