SYSTEM FOR COOLING AN ENGINE OF AN AGRICULTURAL
VEHICLE
BACKGROUND
[0001] The disclosure relates generally to a system for cooling an engine for an agricultural vehicle.
[0002] Generally, harvesters include multiple drums distributed across a width of the harvester. Each drum is configured to harvest crops along a row as the harvester moves across a field. For example, a drum of a cotton harvester may include a rotor with spindles that revolve about the rotor to remove cotton bolls from cotton plants. The harvested goods (e.g., cotton) and other agricultural materials (e.g., chaff, foliage) may be directed through outlets to a bin, baler, or to the field. Further, during harvesting, small pieces of agricultural materials may be distributed throughout the air around the cotton harvester. The small pieces of agricultural materials may interfere with engine cooling components.

DETAILED DESCRIPTION
[0011] One or more specific embodiments of the present disclosure will be described below. In an effort to provide a concise description of these embodiments, all features of

an actual implementation may not be described in the specification. It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation-specific decisions must be made to achieve the developers’ specific goals, such as compliance with system-related and business-related constraints, which may vary from one implementation to another. Moreover, it should be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure.
[0012] When introducing elements of various embodiments of the present disclosure, the articles “a,” “an,” “the,” and “said” are intended to mean that there are one or more of the elements. The terms “comprising,” “including,” and “having” are intended to be inclusive and mean that there may be additional elements other than the listed elements.
[0013] A harvester collects agricultural product and separates portions of the agricultural product into harvested goods (e.g., cotton) and other agricultural product (e.g., chaff, foliage), as the harvester travels across an agricultural field. The harvested goods and the other agricultural product are discharged into outlets, such as a harvested goods outlet and a discharge outlet, respectively. Some of the agricultural product may also be broken down (e.g., into small pieces or dust) and entrained in the air around the harvester. However, the air around the harvester may also be utilized in cooling systems for an engine assembly of the harvester. Thus, in some embodiments, a system includes an engine cover assembly that is configured to physically block the agricultural products from entering an air space utilized by the cooling systems of the engine assembly. Further, the system may include further components to direct the hot air produced by the engine (e.g., the air that contacts an outside surface of the engine or the air that is used in the combustion process of the engine [i.e., exhaust gases]) away from the air space utilized by the cooling system of the engine assembly.
[0014] The disclosed embodiments may block entry and/or accumulation of the agricultural product at the cooling system, thereby improving the effectiveness of the

cooling system. The disclosed embodiments provide a system that may reduce the effect of the agricultural product on the cooling systems, and decrease the time an operator spends removing the agricultural materials.
[0015] While the present disclosure illustrates embodiments of a harvester that includes harvesting components and tractor components to facilitate discussion, it should be understood that the harvester may include components of any of a variety of agricultural or work vehicles, such as trucks, utility vehicles, or the like. For example, harvester components may be coupled to components of a truck to form a harvester. Furthermore, the engine cover assembly may be utilized to increase the effectiveness of cooling systems utilized in any of a variety of agricultural or work vehicles. For example, an engine assembly utilized in any vehicle may benefit from the disclosed engine cover assembly.
[0016] Turning now to the drawings, FIG. 1 is a perspective view of an embodiment of a harvester 10 (e.g., a tractor-mounted harvester or a modified tractor) configured to harvest rows of a crop in an agricultural field. To facilitate discussion, the harvester 10 and its components may be described with reference to a longitudinal axis or direction 12, a vertical axis or direction 14, and a lateral axis or direction 16.
[0017] As shown, the harvester 10 includes multiple drums 18 (e.g., harvesting heads) that utilize one or more rotors to separate harvested goods (e.g., cotton or other agricultural product) from other agricultural materials (e.g., chaff, foliage, stems, debris). The harvester 10 may include an air system that includes a blower 20 (e.g., fan) that is configured to blow air to direct the harvested goods through one or more conduits 22 to a bin 24 (e.g., basket or baler). In some embodiments, the bin 24 may be configured to move (e.g., pivot or rotate) to transfer the harvested goods out of the bin 24 (e.g., to another container or to the agricultural field). In some embodiments, the other agricultural materials may be deposited onto the agricultural field beneath and/or behind the harvester 10.

[0018] In some embodiments, the harvester 10 may include a cabin 32 configured to support or house an operator. It should be understood that the cabin 32 may be an enclosed cabin (e.g., a climate-controlled cabin), as shown, or the cabin 32 may be a platform (e.g., open or non-enclosed platform) on which the operator may sit or stand, for example. In the illustrated embodiment, the cabin 32 includes one or more operator interfaces and/or input devices 34 (e.g., switch, knob, light, display, steering wheel, gear shift lever) that enable the operator to monitor and/or control various functions of the harvester 10, such as ground speed, steering angle, transmission range and/or gear, operation of the HVAC system, or the like. As shown, a frame assembly 30 (e.g., harvester frame or chassis) includes a first frame portion 36 (e.g., harvester frame or chassis) and a second frame portion 40 (e.g., tractor frame or chassis). As shown, the bin 24 and the cabin 32 are supported on the first frame portion 36. Various other components (e.g., the drums 18, the blower 20, the one or more conduits 22, the drive system 30) may be supported by and/or coupled to the first frame portion 36 to form the harvester 10. In the illustrated embodiment, the first frame portion 36 supports or includes a cover assembly 38 (e.g., cage assembly) that is configured to cover (e.g., surround or protect) various components, such as an engine, a transmission, an HVAC system, and/or a radiator, which are supported on the second frame portion 40. In operation, the harvester 10 may be driven in a direction of travel 42 through the agricultural field using forward wheels 44 and rear wheels 46.
[0019] As discussed above, the harvester 10 may include harvester components and tractor components. For example, in the illustrated embodiment, the forward wheels 44, the rear wheels 42, the second frame portion 40, and various components supported on the second frame portion 40, such as the engine, the transmission, the HVAC system, and/or the radiator, may form a tractor assembly 48 that may be coupled to other tractor components (e.g., tractor hood, tractor cabin, or the like) to form a tractor (e.g., an unmodified tractor). The drums 18, the blower 20, the one or more conduits 22, the bin 24, the cabin 32, the input devices 34, the first frame portion 36, and/or the cover assembly 38 may be part of a harvester assembly 52 (e.g., harvester kit or conversion kit)

that may be coupled to the tractor assembly 48 to create or to build the harvester 10. Thus, at certain times of the year, the operator may utilize the tractor assembly 48 as part of a tractor to carry out various agricultural operations. However, during a harvesting season, the operator may separate the tractor assembly 48 from other tractor components of the tractor, and then the operator may combine the tractor assembly 48 with the harvester assembly 52 to build the harvester 10 to carry out harvesting operations. At the conclusion of the harvesting season, the operator may separate the tractor assembly 48 from the harvester assembly 52, and then reassemble the tractor components on the tractor assembly 48 to form the tractor to resume the various agricultural operations.
[0020] It should be appreciated that although two drums 18 are shown in FIG. 1, that the harvester 10 may have any suitable number of drums 18, such as 1, 2, 3, 4, 5, 6, or more drums 18. It should also be appreciated that the harvester 10 may include tracks in place of front wheels 44 and/or rear wheels 46.
[0021] FIG. 2 is a side view of the tractor assembly 48 and the harvester assembly 52 that may be coupled to one another to form the harvester 10, in accordance with an embodiment of the present disclosure. The tractor assembly 48 may include the forward wheels 44, the rear wheels 46, the second frame portion 40, and/or various other components supported on the second frame portion 40. For example, the tractor assembly 48 may include powertrain components, such as an engine 70, a transmission 72, and/or other components that transmit power from the engine 70 to axles to drive rotation of the forward wheels 44 and the rear wheels 46. In some embodiments, the tractor assembly 48 may include various other components, such as an HVAC system 74 (e.g., compressor and condenser) and/or a radiator 76. When the tractor assembly 48 is not coupled to the harvester assembly 52, the tractor assembly 48 may be coupled to various other tractor components, such as a tractor hood, tractor cabin, tractor input devices, or the like, to form a tractor (e.g., an unmodified tractor) and to enable the tractor to travel in a forward direction 78 to carry out various agricultural operations (e.g., non-harvesting operations).

[0022] As shown, the harvester assembly 52 includes the drums 18, the blower 20, the one or more conduits 22, the bin 24, the cabin 32, the input devices 34, the first frame portion 36, and the cover assembly 38, among other components. The harvester assembly 52 may be coupled to the tractor assembly 48 (e.g., via fasteners) to form the harvester 10 to travel in the forward direction 42 through the agricultural field. The harvester assembly 52 may be coupled to the tractor assembly 48 via any of a variety of processes or steps. For example, in some embodiments, the harvester assembly 52 is partially assembled or fully assembled (e.g., as shown), and then subsequently coupled or mounted onto the tractor assembly 48 to form the harvester 10. In some embodiments, the components of the harvester assembly 52 may be coupled individually and/or sequentially to the tractor assembly 48.
[0023] FIG. 3 is a perspective view of an engine cover assembly 80 that may be part of the harvester assembly 52, and/or that may be coupled to the tractor assembly 48, in accordance with an embodiment of the present disclosure. As shown, the engine cover assembly 80 includes a hot chamber assembly 82, a cold chamber assembly 84, and an exhaust section 86. In the present embodiment, the components of the engine cover assembly 80 are coupled to the frame assembly 30 (e.g., by bolts and/or welds). In some embodiments, the components of the engine cover assembly 80 may be coupled to one another and may be configured to be placed over portions of the frame assembly 30. Further, certain components of the engine cover assembly 80 may be composed of sheet metal and are configured to at least partially enclose one or more of the components of the engine assembly, thereby blocking entrained agricultural product from reaching the components of the engine assembly 80. For example, the hot chamber assembly 82 defines a hot chamber and at least partially encloses the engine, transmission, and one or more components of the cooling system (e.g., the radiator and radiator fan). Further, the cold chamber assembly 84 defines a cold chamber and at least partially encloses one or more components of the cooling system. In addition, the exhaust section 86 receives exhaust gases from the engine of the engine assembly, and directs the exhaust gases in

the longitudinal direction 12 towards the rear of the harvester assembly 52 and away from the cold chamber assembly 84.
[0024] As shown, the cold chamber assembly 84 includes a cold chamber top panel 90, a cold chamber side panel 92, and a cold chamber door 94. In addition, the cold chamber assembly 84 includes panels on other sides, such that the panels of the cold chamber assembly 84 (e.g., the cold chamber top panel 90, the cold chamber side panel 92, and other panels hidden from view) form an enclosed box. In the present embodiment, the cold chamber assembly 84 includes six sides. In other embodiments, the cold chamber assembly may include any number of suitable sides, including 3, 4, 5, 7, 8, or more. In other embodiments, the cold chamber assembly may not be enclosed, and one or more sides of the cold chamber assembly may be open.
[0025] In the present embodiment, the cold chamber assembly 84 is supported by an axle of the rear wheels 46. In some embodiments, the cold chamber assembly may be coupled to the axle of the rear wheels, the frame, or any other component of the harvester assembly. Further, each of the panels of the cold chamber assembly 84 may be composed of one or more panels coupled together (e.g., by fasteners or welds).
[0026] Further, the cold chamber door 94 is coupled to the cold chamber side panel 92. In the present embodiment, the cold chamber door 94 is coupled by fasteners (e.g., bolts) that may be removable to enable the cold chamber door 94 to be removed from the cold chamber side panel 92. Removal of the cold chamber door 94 may enable access to the interior of the cold chamber assembly 84, which may enable inspection, cleaning, or maintenance of the cold chamber assembly 84 or components of the cooling system enclosed within the cold chamber assembly 84. Further, the cold chamber door 94 may be included on any of the panels, and the cold chamber assembly 84 may include any suitable number of cold chamber doors, including 2, 3, 4, 5, 6, or more.
[0027] In addition, some or all of the panels of the cold chamber assembly 84 are perforated sheets having openings distributed along the surface of the panels. For

example, the openings may be perforations (e.g., thru-holes) or slats that enable air to flow through, but block at least some of the agricultural product from passing through. In some embodiments, the openings may be the only inlet through which air flows into the cold chamber assembly 84. In some embodiments, the perforations may be holes that are drilled or stamped in the panels, and may include a radius equal to or less than 0.5 millimeters (mm), 1mm, 2mm, 5mm, or more. In some embodiments the perforations may be approximately 0.25 mm to 5 mm, 0.5 mm to 3 mm, or 1 mm to 2 mm. Further, the perforations may be distributed in a pattern (e.g., rows and columns, a circular pattern, etc.), randomly, or along a portion (e.g., on one half or any other suitable portion) across the surface of each of the panels. Further, the perforations may be any suitable shape, including triangles, quadrilaterals, pentagons, hexagon, other polygons, curved shapes, or any other shape. In addition, the each panel may include any combination of different shapes of perforations. Moreover, the perforations may be distributed along the surfaces of only some of the panels (e.g., along 1, 2, 3, 4, or 5 of the panels).
[0028] As shown, the hot chamber assembly 82 includes a hot chamber side panel 100 and a hot chamber top panel 102. In addition, the hot chamber assembly 82 includes panels on other sides, such that the panels of the hot chamber assembly 82 (e.g., the hot chamber top panel 100, the hot chamber side panel 102, and other panels hidden from view) form a partially enclosed box. In other embodiments, the hot chamber may be enclosed and/or include any suitable number of panels, including 3, 4, 5, 6, 7, 8, or more.
[0029] As shown, the hot chamber side panel 100 includes horizontal slats 106 and angled slats 108 that extend through the hot chamber side panel 100 and fluidly couple the interior of the hot chamber assembly 82 and the ambient air outside the hot chamber assembly 82. The engine contained within the hot chamber assembly 82 produces substantial heat during operation. The horizontal slats 106 and the angled slats 108 enable the heat produced by the engine to flow away from the engine, while maintaining a physical obstruction around the engine. As shown, the horizontal slats 106 extend in substantially straight lines substantially horizontal with respect to the ground and parallel

to the longitudinal direction 12, and the angled slats 108 extend in substantially straight lines at an angle relative to the ground. The angled slats 108 may extend at substantially the same angle as a side panel edge 110 with respect to the longitudinal direction 12. In some embodiments, the horizontal slats and the angled slats may extend at any suitable angle with respect to the longitudinal direction 72, including 30 degrees, 45 degrees, 60 degrees, 90 degrees, 120 degrees, 135 degrees, 150 degrees, or any other angle. Further, in some embodiments, the horizontal slats and the angled slats may extend in any shape along the hot chamber side panel (e.g., wavy, curved, or circular). Moreover, the horizontal slats and the angled slats may be included in any of the hot chamber panels.
[0030] As shown, the angled slats 108 include louvers that direct the heat to flow in the vertical direction 14 and towards the front of the tractor assembly 48. Specifically, the louvers extend laterally-inwardly from a top edge of the angled slats 108. This orientation of the louvers directs the heat flowing out of the hot chamber assembly 82 away from the cold chamber assembly 84. In some embodiments, the horizontal slats may also include louvers.
[0031] In the present embodiment, the hot chamber side panel 100 includes additional structure to direct the heat flowing out of the hot chamber assembly 82 away from the cold chamber assembly 84. For example, the hot chamber side panel 100 includes a closed section 112 disposed below the angled slats 108 and proximal to the cold chamber assembly 84. The closed section 112 is a solid section that substantially blocks hot air from flowing through, which may block hot air from escaping the hot chamber assembly 82 in an area proximal to the cold chamber assembly 84. The closed section 112 may decrease the temperature of the air surrounding and entering the cold chamber assembly 84.
[0032] As shown, the hot chamber side panel 100 includes structure to enable access to engine components interior to the hot chamber assembly 82. For example, the hot chamber side panel 100 may include an opening and/or a fuel door 114, which may be removable to enable access to a fuel neck and fuel tank. For example, the fuel door 114

may be coupled by bolts that may be removed to enable removal of the fuel door 114, the fuel door 114 may be coupled to a hinge that enables the fuel door 114 to open, or the fuel door 114 may include any other suitable structure enabling removal of the fuel door 114.
[0033] In addition, the hot chamber side panel 100 includes hinges 116 that enable the hot chamber side panel 100 to rotate about a rotational axis that is parallel to the longitudinal direction 12, which may expose the engine components interior to the hot chamber assembly 82. In the present embodiments the hinges 116 are coupled (e.g., by bolts or welds) to the first frame portion 36 and the hot chamber side panel 100. In other embodiments, there may be any suitable number of hinges, including 1, 3, 4, 5, 6, or more. Further, in other embodiments, the hinges may be coupled to other structure or in multiple places of the harvester assembly. For example, the hinges may be coupled to the hot chamber top panel and the hot chamber side panel.
[0034] FIG. 4 is a perspective view of another side of the engine cover assembly 80 of FIG. 3, in accordance with an embodiment of the present disclosure. As shown, the hot chamber assembly 82 includes the hot chamber top panel 102 and a closed hot chamber side panel 120 (e.g., laterally opposed to the hot chamber side panel 100 of FIG. 3). In the present embodiment, the closed hot chamber side panel 120 does not fluidly couple the interior of the hot chamber assembly 82 to the exterior of the hot chamber assembly 82. Further, the closed hot chamber side panel 120 is composed of two metal sheets coupled (e.g., by bolts or welds) to the first frame portion 36. In other embodiments, the closed hot chamber side panel may be composed of any suitable number of metal sheets, including 1, 3, 4, 5, 6, or more.
[0035] As shown, the harvester assembly 52 also includes the exhaust section 86, which is open at a first end 122 (e.g., along a laterally-inner side proximal to the first end) and a second end 124. The exhaust section 86 receives the exhaust gases from the engine at the first end 122, and the exhaust gases travel through the exhaust section 86 in the longitudinal direction 12, and exit the exhaust section 86 through the second end 124.

For example, the exhaust section 86 is an enclosed section composed of one or more sheets of metal coupled together. Further, the exhaust gases may pass from a component (e.g., an engine) contained within the interior of the hot chamber assembly 82 and into the exhaust section 86 via an opening at the first end 122. Then, the exhaust gases travel through the exhaust section 86, and exit the exhaust section 86 via an opening at the second end 124 and enter the ambient air. The exhaust section 86 may extend in the longitudinal direction 12 to any suitable distance. For example, the exhaust section 86 may extend beyond the cold chamber assembly 84, such that the exhaust gases are expelled into an area where the exhaust gases will not enter the cold chamber assembly 84. In some embodiments, the exhaust system 86 may cover an exhaust pipe and block agricultural product from contacting the exhaust pipe.
[0036] FIG. 5 is a perspective view of the engine cover assembly 80 with the hot chamber assembly hidden from view, in accordance with an embodiment of the present disclosure. As shown, the cold chamber assembly 84 includes the cold chamber top panel 90, the cold chamber side panel 92, and a cold chamber sealing panel 130. The cold chamber sealing panel 130 forms part of the enclosed box of the cold chamber assembly 84 and separates the cold chamber from the hot chamber. The cold chamber sealing panel 130 may be a solid sheet that is devoid of openings or perforations, thereby blocking air flow thru or across the cold chamber sealing panel 130 between the cold chamber and the hot chamber. In the present embodiment, the cold chamber assembly 84 encloses the radiator of the cooling assembly 132, and a portion of the cooling hoses 136.
[0037] As shown, the engine 70, the transmission 72, and the cooling assembly 132 are now exposed. The cooling assembly 132 may be utilized to provide cooling to the engine 70. As discussed above, one or more components of the cooling system 132 may be contained within the cold chamber assembly 84. In addition, the cold chamber assembly 84 includes a sealing plate 138 disposed around a condenser 134 of a heating ventilation and cold air conditioning system (HVAC). The sealing plate 138 and the condenser 134, in combination with the cold chamber sealing panel 130 may separate and

isolate the hot chamber from the cold chamber. It should be understood that these components may have any suitable form. For example, if the HVAC system is not present, the sealing panel 130 may seal and extend across an entire space to isolate the hot chamber from the cold chamber with only openings to enable the cooling hoses 136 to extend thru the sealing panel 130.
[0038] Specifically, the radiator is disposed in the cold chamber assembly 84, and the radiator includes passages through which a fluid may flow. In some embodiments, the radiator may also include fins disposed along the outside of the passageways to increase the rate of heat transfer between the air outside of the passageways and the fluid contained within the passageways. The radiator fan 134 sucks air from the cold chamber assembly 84, over the radiator, and into the hot chamber assembly, which further increases the rate of heat transfer between the air outside of the radiator and the fluid contained within the passageways of the radiator. Then, the fluid in the passageways of the radiator may be sent to other areas of the engine 70 via the cooling hoses 136, which may enable more effective cooling of internal components of the engine 70, or provide additional cooling to particular components of the engine 70.
[0039] Utilizing the cold chamber sealing panel 130 and the sealing plate 138 may block hot air in the hot chamber assembly from flowing into the cold chamber assembly 84, which may increase the efficiency of the cooling system 132. In the present embodiment, the sealing plate 138 is a solid plate (e.g., metal, rubber, polymer, or other suitable sealing material) coupled (e.g., by bolts or welds) to the cold chamber sealing panel 130, and contains at least one opening to enable the cooling hoses 136 to pass through. In some embodiments, the sealing plate may be integral to the cold chamber sealing panel or the radiator. In some embodiments, the sealing plate may extend toward the engine to further enclose the radiator fan.
[0040] FIG. 6 is a close-up view of the angled slats 108 with louvers 160 taken along a section 150 of FIG. 3, in accordance with an embodiment of the present disclosure. As discussed above, the louvers 160 are coupled to or integral to the angled slats 108 at a top

edge 162 of each of the angled slats 108, and the louvers 160 are angled toward the interior of the hot chamber assembly 80. In the present embodiment, the orientation of the louvers 160 directs air to flow out of the hot chamber assembly 80 along a flow path 164, which is generally in the vertical direction 14 and toward the front of the tractor assembly. Further, as discussed above, the flow path 164 is directed away from the cold chamber assembly, which may increase the efficiency of the cold chamber assembly. In other embodiments, the louvers may be oriented in other directions. For example, the louvers may be coupled to or integral to a bottom side of the angled slats, and the louvers may be angled towards the exterior of the hot chamber assembly.
[0041] While only certain features of the disclosure have been illustrated and described herein, many modifications and changes will occur to those skilled in the art. It is, therefore, to be understood that the appended claims are intended to cover all such modifications and changes as fall within the true spirit of the disclosure.
