  • Publication number: 20150198385
    Abstract: A heat exchanger for a work vehicle is provided that comprises a tube layer (102) made of a plurality of elongate tubes (108) that are spaced apart by gaps (112) oriented parallel to each other in a first direction; a first fin layer (100) in the form of a corrugated sheet having a plurality of corrugations, wherein the plurality of corrugations of the first fin layer (100) facing the tube layer (102) define channels (106) for passing therethrough a fluid different from the first fluid; and a first fluid guide layer (200) formed of a planar sheet that extends across and encloses the plurality of corrugations of the first fin layer (100) over substantially an entire length of the plurality of corrugations.

  • Patent number: 8800538
    Abstract: A diesel fuel supply circuit comprises a diesel engine (100); a fuel cooler (104); a fuel tank (102), and a valve (114). The valve (114) is operable to move the fuel cooler (104) from (1) a position within the circuit in which it cools fuel leaving the diesel engine (100) and going to the fuel tank (102) to (2) a position in which it cools fuel leaving the fuel tank (102) and going to the diesel engine (100) and vice versa.

  • Patent number: 8038518
    Abstract: An agricultural combine includes a supporting structure. A work assembly is coupled to the supporting structure. The work assembly has a plurality of components to assist in the performing of crop processing operations. The work assembly is configured to define an air stream path. The work assembly has at least one rotary component that generates an air stream that flows through the air stream path to aid in crop processing in the work assembly. A fluid system is configured to circulate a fluid. The fluid system includes a fluid cooler that is positioned at a location in the air stream path to provide cooling of the fluid.

  • Patent number: 7875093
    Abstract: An air filter arrangement for an agricultural combine located on a panel at a side wall of the agricultural combine. The air filter arrangement includes a rotary filter mounted for rotation at a first aperture, a scoop enclosing the rotary filter and blocking substantially all air flow to the rotary filter except at a scoop inlet disposed along an upper edge of the scoop above the rotary filter, and at least one stationary filter disposed to filter air passing through a second aperture in the panel, the stationary filter being located between an upper portion of the rotary filter and the scoop inlet.
