Air flow arrangement for a stand-by electric generator

An air flow structure for controlling the flow of air over a generator set including an alternator, an engine driving the alternator, and an exhaust discharge tube having an outlet for discharging engine exhaust generated during the operation thereof, the air flow structure comprising:

• an enclosure for a generator having first and second opposite ends and defining a forward compartment, an engine compartment and an exhaust compartment for receiving the outlet of the exhaust discharge tube,
• a first air flow generator positioned within the enclosure for drawing ambient air defined by first and second portions into the forward compartment through the first end of the enclosure, the first flow generator directing a first portion of air across the engine;
• and
• a second air flow generator positioned within the enclosure, the second air flow generator:
• drawing the second portion of ambient air over the alternator;
• combining the first portion of ambient air directed over the engine and the second portion of ambient air drawn over the alternator and urging the combined air into the exhaust compartment;
• and
• urging the combined air and the engine exhaust from the exhaust compartment through the second end of the enclosure.
