摘要： A heat management system for air-cooled engines suitable to power yard care equipment or vehicles. The system may generally comprise an engine, a blower configured to blow ambient cooling air across the engine, and an exhaust system comprising an exhaust header and a muffler. The exhaust header has an inlet end which receives heated exhaust gas from the engine and an outlet end fluidly coupled to the muffler. An air control baffle is configured to redirect a portion of the cooling air from the blower towards the exhaust header and the muffler to enhance cooling the exhaust system. The system may further include an outermost protective shield exposed to equipment operators and an inner heat barrier or shield located between the muffler and protective shield. The system is designed to ameliorate both radiative and convective sources of heat transfer to maintain the protective shield at temperatures below established industry standards.

摘要： A fan shroud and a blower device are provided. The fan shroud includes a shroud wall surface and a plurality of ventilation openings. The shroud wall surface extends around a fan along a radial direction orthogonal to a rotation axis. The plurality of ventilation openings are formed through the shroud wall surface in a thickness direction of the shroud wall surface to allow passing of wind generated by a fan motor. A width of a wall surface side opening on a downstream side of the wind in the ventilation opening is smaller than a width of a lateral wall side opening on an upstream side of the wind in the ventilation opening.

摘要： Methods, apparatus, systems, and articles of manufacture are disclosed to remove dust from an electronic device. An example apparatus includes a fan to rotate in a first direction in a first mode of operation of the electronic device, the first mode of operation corresponding to user operation of the electronic device, at least one memory, machine readable instructions, and processor circuitry to at least one of instantiate or execute the machine readable instructions to determine an operation time of the fan in the first mode of operation, and cause the fan to operate in a second mode of operation based on the operation time exceeding a threshold time, and, wherein in the second mode, pulsed power is applied to the fan to rotate the fan in a second direction opposite the first direction.

摘要： A standby generator includes a standby generator enclosure having a partition wall separating a first end from an opposite second end of the enclosure, one or more airflow openings, and a first air duct and a second air duct each coupled to at least one of the one or more airflow openings. An engine mounts in the enclosure toward the first end from the partition wall, and an alternator driven by the engine mounts in the enclosure toward the second end from the partition wall. The engine includes an engine cooling fan that faces the first end to drive engine cooling air received from the first air duct toward the first end, and the alternator includes an alternator cooling fan that faces the second end to drive alternator cooling air received from the second air duct toward the second end.

摘要： A construction machine in which an electrical unit can be reliably cooled at low cost by effectively utilizing an intake pipe connected to an intake port of an engine. This construction machine includes: an engine; and a hood covering the engine, wherein a space inside the hood has a placement space in which an electrical unit is placed and which communicates with outside air, and a distal-end opening of an intake pipe connected to an inlet port of the engine is disposed in the placement space to cause outside air sucked into the intake pipe due to a suction pressure occurred in the intake pipe to pass through the placement space to form a cooling air path in the placement space.

摘要： A cooling device includes a surrounding member, an air inlet, an air outlet, and a flow-path-formation mechanism. The surrounding member is configured to surround an engine. The air inlet is formed in the surrounding member. The air outlet is formed in the surrounding member and is to be coupled to an intake pipe of the engine. The flow-path-formation mechanism is configured to form a flow path that allows outside air to circulate to the air outlet from the air inlet when a temperature of the engine or a temperature inside the surrounding member is greater than or equal to a predetermined temperature.

摘要： A genset enclosure includes a frame system, a plurality of side panels, a plurality of roof panels, a first connector, and a second connector. The frame system includes a plurality of interconnected frame members. The plurality of side panels are coupled to opposing sides of the frame system. The plurality of roof panels are coupled to a roof of the frame system and extend between the opposing sides of the frame system. The plurality of roof panels are oriented perpendicular to the plurality of side panels. The frame system, the plurality of side panels, and the plurality of roof panels together define an enclosure portion having a first open end and a second open end. The first connector and second connector are engageable with one another and are coupled to the frame system along a perimeter of the first open end and the second open end, respectively.

摘要： The invention relates to an oil system (7) comprising a pump arrangement (11); a first gallery (13) for providing oil to a first engine site (14); a second gallery (15) for providing oil to a second engine site (16); a second gallery flow control device (25) for controlling flow of oil from the pump arrangement (11) to the second gallery (15); control circuitry (5); a first pressure sensor (27) for sensing the oil pressure in the first gallery (13); and a second pressure sensor (29) for sensing the oil pressure in the second gallery (15). The oil system (7) is controllable between: a first state in which the control circuitry (5) controls the second gallery flow control device (25) to an open state, and controls an oil pressure in the second gallery (15) by controlling the pump arrangement (11); and a second state in which the control circuitry (5) controls an oil pressure in the first gallery (13) by controlling the pump arrangement (11), and controls the oil pressure in the second gallery (15) by controlling the second gallery flow control device (25).

摘要： A pneumatic motor assembly that includes a pneumatic motor, which is driven by a compressed gas. The pneumatic motor assembly has a magnet assembly that magnetically couples the pneumatic motor assembly to an implement. After having being used to drive a pneumatic motor, the gas, which has expanded and become colder, cools the magnet assembly The pneumatic motor assembly can thus enable the use to the implement at temperatures at which the magnet assembly would otherwise reach or exceed the maximum operating temperature of the magnet assembly. A flow induction system that includes the pneumatic motor assembly. A method of operating a pneumatic motor assembly that also cools a magnet assembly that is part of the pneumatic motor assembly.
