Abstract: A work vehicle includes a vehicle body frame, an outer cover, an engine compartment, a cooling compartment, a partition wall, an inverter, and a capacitor. The engine compartment contains an engine. The cooling compartment contains a cooling device. The partition wall separates the cooling compartment from the engine compartment. The inverter and the capacitor are disposed between the partition wall and the cooling device. The inverter is positioned above the capacitor. A length of the capacitor in the vehicle width direction is greater than a length of the inverter in the vehicle width direction. At least one of a first side surface of the outer cover positioned leftwards of the left side surface of the inverter and a second side surface of the outer cover positioned rightwards of a right side surface of the inverter is separated from the inverter by a gap.

Abstract: A method of cooling an engine of a vehicle includes measuring a temperature of a cylinder head of the engine, determining whether the measured temperature of the cylinder head may be equal to or lower than a predetermined temperature, when the temperature of the cylinder head may be equal to or lower than the predetermined temperature, moving coolant of the cylinder head and a cylinder block to a separate coolant tank, determining whether the measured temperature of the cylinder head may be equal to or higher than a specific temperature, and when the measured temperature of the cylinder head may be equal to or higher than the specific temperature, supplying coolant stored in the coolant tank to the cylinder head or the cylinder block.

Abstract: An intake-side space around intake ports and an exhaust-side lower space around exhaust ports are provided in a main cooling jacket portion. These spaces are connected to each other. In a sub cooling jacket portion, an exhaust-side upper space is provided at a level above the exhaust-side lower space. The main cooling jacket portion and the sub cooling jacket portion are connected to each other via a cylindrical-hole connecting passage extending vertically and separate from each other vertically via a wall portion in another area than the connecting passage. Accordingly, a cooling device of an engine which can restrain the exhaust gas from being cooled too much improperly is provided.

Abstract: There are provided first and second water supply passages to supply cooling water from an engine to first and second center housings of first and second turbochargers, and first and second return passages to return the cooling water from the first and second turbochargers to the engine. A cooling-water connection portion of the first water supply is located above the level of a cooling-water connection portion of the second water supply passage. A vapor releasing passage is provided between the second turbocharger and an upper tank provided on the outside of an engine body at a position located above the connection portion of the second return passage of the second turbocharger. Accordingly, the function of vapor releasing from the first and second turbochargers can be improved, thereby increasing the layout flexibility around the engine.

Abstract: A cooler block for an agricultural tractor comprising a cooler assembly mounted on a radiator and coupled to the radiator by upper and lower linkages. The cooler assembly can be moved between a first position in which the cooler assembly lies parallel to the radiator and a second position in which the cooler assembly is inclined relative to the radiator. The cooler assembly is pivotable about a pivot in the upper linkage that is itself movable relative to the radiator. The lower linkage allows the entire cooler assembly to rise and the pivot of the upper linkage to move away from the radiator as the cooler assembly is pivoted from the first to the second position. A detent is incorporated into one of the two linkages to retain the cooler assembly in the second position.

Abstract: A radiator mounting system for a skid steer vehicle includes an air box with a front wall having an opening sized to receive engine fan blades, an oil cooler disposed in the air box, a radiator; and a radiator frame supporting the radiator that is hingeably coupled to the air box. The radiator has plastic tanks and an aluminum core and the frame extends around the periphery of the radiator.

Abstract: A motor-fan shroud is formed at its lower portion with a supporting portion having a hole and at its upper portion with a first and second clip portions arranged apart from each other in a width direction. A reservoir tank is formed at its lower portion with a projection extending downward and insertable into the hole of the supporting portion and at its upper portion with a first and second ear portions insertable from above into the first and second clip portions, respectively. A first clipping surface of the first clip portion has a substantial half-ball shaped projection to be fitted in a hole of the first ear portion, while the second ear portion has a claw to be latched by the second clip portion so that unlatch, in an upward direction, of them can be prevented.

Abstract: A cooler arrangement for agricultural implements, particularly for tractors is quickly and easily moved to permit access thereto for cleaning. The cooler block contains at least a front cooler, a central cooler, and a rear cooler. The rear cooler is attached at a fixed position on the frame of the agricultural tractor and the central cooler can be moved away from the rear cooler while the front cooler can also be moved away from the central cooler. The front cooler is suspended so that is can move sufficiently upwardly and, if necessary, also forwardly, that the central cooler can be swung away from the rear cooler unhindered to the side at about a right angle. The front cooler is joined to a tilting mechanism having a lever arm pointing in the direction of travel of the tractor.

Abstract: A cooling system support structure for removably supporting a cooling system module on a vehicle chassis is disclosed. The structure includes a frame having first and second sides and configured to support the cooling system module, first and second mounting points coaxially mounted along the first side and a third mounting point mounted along the second side. The mounting points are positioned to mate with corresponding chassis mounts on the vehicle chassis and a flexible coupling is provided for connecting each mounting point to the respective chassis mount such that the frame is movably supported by the vehicle chassis.

Abstract: A radiator for earth moving machines connected to the engine of the earth moving machine and comprising first connecting means that pivotally fasten the radiator to the frame, in such a way that the radiator can rotate about its own lower edge from a closed position in which it is approached to the frame to an open position in which it is in part moved away from the frame. The first connecting means comprise a plurality of support elements each integrally fastened to the frame in correspondence with the lower edge of the radiator. Each support element has a saddle shaped portion oriented upwards, into which is inserted the lower edge of the radiator.

Abstract: A radiator system for mounting on the engine hood of an automobile having a rear engine comprising a generally panel-type radiator, a support for holding the radiator in a generally horizontal disposition and for securing the radiator to the engine hood, an inlet conduit for transferring heated engine coolant from the engine into the radiator, and an outlet conduit for transferring cooled engine coolant from the radiator to the engine.

Abstract: A portable, self-contained apparatus for cooling automotive engine fluid, e.g. engine coolant, includes quick couplers for connection to an automotive engine. The apparatus receives hot engine fluid from the engine, cools the engine fluid, and returns the cooled engine fluid to the engine. A fluid reservoir and one or more heat exchangers aid in the cooling process. Corresponding methods provide similar advantages.
