Abstract: 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.

Abstract: Disclosed example power systems include an enclosure, an engine within the enclosure; and a generator within the enclosure and configured to convert mechanical power from the engine to electrical power. The enclosure includes a first air inlet on a first end of the enclosure, a first air outlet on a top of the enclosure, and a second air inlet on a side of the enclosure to provide a second airflow through the enclosure. The power system further includes an engine fan configured to generate a first airflow from the first air inlet to the first air outlet to cool the engine. The power system includes a diverter located below the first air outlet and configured to direct environmental contaminants away from at least one of the engine or the generator, where the environmental contaminants enter the enclosure through the first air outlet.

Abstract: 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.

Abstract: 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.
