Standby generator air flow management system

A multi-chamber standby generator comprising:

• a multi-chamber generator enclosure comprising a partition wall that forms at least a first chamber and a second chamber, the first chamber and the second chamber each comprising an air inlet and an air outlet;
• a first air duct coupled to the air inlet of the first chamber;
• a second air duct coupled to the air inlet of the second chamber;
• an air-cooled engine located in the first chamber, the air-cooled engine comprising an engine cooling fan coupled to the air inlet of the first chamber by the first air duct;
• and
• an alternator driven by the air-cooled engine and located in the second chamber, the alternator comprising an alternator cooling fan coupled to the air inlet of the second chamber by the second air duct.

A generator comprising:

• a generator enclosure comprising a first end and a second end opposite the first end, the generator enclosure comprising a plurality of airflow openings that includes an airflow opening in the first end and an airflow opening in the second end;
• an engine and an alternator driven by the engine mounted in the enclosure, the engine and alternator mounted in a horizontal crankshaft orientation with the engine positioned toward the first end of the enclosure and the alternator positioned toward the second end of the enclosure;
• an engine cooling fan driven by the engine and positioned on a side of the engine opposite from the first end of the enclosure;
• and
• an alternator cooling fan coupled to the alternator and driven by the engine, the alternator cooling fan positioned on a side of the alternator opposite from the first end of the enclosure;
• wherein an exhaust side of the engine cooling fan faces the first end of the enclosure and an exhaust side of the alternator cooling fan faces the second end of the enclosure.
