摘要： A method is provided for facilitating the cooling of engine coolant flowing through a radiator operatively connected to the engine. The method includes the steps of monitoring the temperature of the engine coolant flowing through the radiator and positioning a fan adjacent the radiator. The fan is initially rotated at a predetermined speed. Thereafter, the speed of the fan is varied in response to the temperature of the engine coolant.

摘要： A generator structure is provided having an improved air flow arrangement. The generator structure includes an enclosure having an interior for receiving an engine and an alternator therein. A roof structure is positioned on the enclosure and includes an eave portion and an attic portion. The eave portion has an inlet which communicates with the ambient air external of the generator structure, an outlet communicating with the interior of the enclosure and input flow path therebetween. The attic portion has an inlet communicating with the interior of the enclosure, an outlet communicating with the ambient air external of the generator structure and an exit flow path therebetween. An air flow generator draws ambient air through the inlet flow path in the eave portion of the roof structure into the interior of the enclosure to cool the engine and the alternator and urges air from the interior of the enclosure through the exit flow path in the attic portion and out of the generator structure.

摘要： An apparatus and method are provided for facilitating the cooling of engine coolant flowing through a radiator operatively connected to the engine of an engine-driven, electrical generator set. The engine has a crankshaft rotatable about a first axis and a radiator having a first side directed towards the engine and a second side. The apparatus includes a fan positionable on the second side of the radiator that is rotatable about a second axis generally parallel to and vertically spaced from the first axis. The apparatus includes a thermally responsive clutch having a driven portion. The clutch is movable between a first disengaged position wherein the driven portion is isolated from the crankshaft and a second engaged position wherein the driven portion rotates in unison with the crankshaft in response to a predetermined temperature. A fan drive system interconnects the driven portion of the clutch and the fan for translating rotation of the driven portion to the fan.

摘要： Fuel cell stacks and systems with thermal management systems to deliver a liquid heat exchange fluid into thermal communication with the stack and thereafter recycle the stream. In some embodiments, the system is adapted to selectively apportion the recycled liquid stream between a stream that, prior to reuse as a heat exchange stream, is returned to a fluid reservoir and/or selectively cooled, and/or selectively returned to the reservoir and mixed with heat exchange fluid in the reservoir, and a stream that is returned into thermal communication with the stack without returning the stream to the reservoir and/or without heating or cooling and/or without being mixed with additional heat exchange fluid. In some embodiments, the system is adapted to automatically apportion the recycled stream responsive to its temperature. In some embodiments, the system includes a thermostatic valve and/or selectively apportions the recycled stream without requiring an electronic controller or manual input.

摘要： A fan drive arrangement and method is provided for facilitating the cooling of engine coolant flowing through a radiator and an engine. The fan drive arrangement includes a variable pitch sheave assembly which moves between a first high speed position and a second low speed position. Variable pitch sheave assembly is interconnected by first and second drive belts to first and second drive pulleys operatively connected to the crankshaft of the engine and by first and second fan belts to corresponding fan pulleys connected to a fan shaft of a fan. Variable pitch sheave assembly includes first and second drive belt receiving grooves for receiving corresponding drive belts therein and first and second fan belt grooves for receiving corresponding fan belts therein. The depths of the fan belt grooves and the drive belt grooves of the variable pitch sheave assembly are varied in response to the temperature of the engine coolant flowing through the radiator so as to vary the fan speed accordingly.
