Adjustable cover for air recirculation in a generator power supply

Abstract:

A welding power supply having an adjustable cover is disclosed. The welding power supply includes an enclosure housing an engine, a porous radiator thermally coupled to the engine, and a fan configured to propel air through the radiator. A ventilation opening is in fluid communication with the fan and radiator. The fan is configured to move heated air along an air path and out of the ventilation opening. The air may be heated by the welding power supply components (e.g. engine, radiator, charge air cooler, oil cooler, compressor, generator, weld circuitry, and/or other components), for example. The adjustable cover is positioned over the ventilation when in a fully closed and/or partially open/closed position. The adjustable cover may be moved between fully closed, partially open/closed, and fully open positions. The amount of air that is allowed to exit the enclosure, and the amount of air that is recirculated within the enclosure, may be altered by adjusting the position of the adjustable cover.
