Abstract
An enclosure (10) is provided for storing a battery (12) or other device that emits hydrogen or other potentially explosive, lighter-than-air gas during operation. The enclosure includes a floor (14), ceiling (16) and side walls (18) defining a substantially air-tight interior space, and a ventilation system for venting the low density gas from the space. The ventilation system includes a first passageway (20) extending through the side wall (18) into an upper end of the space and including an inlet (24) disposed in the interior space at the upper end and an outlet (26) disposed outside the space. Also, the system includes a second passageway (22, 42) that extends into a lower end of the space, terminating at an outlet disposed within the enclosure adjacent the upper end of the interior space. The second passageway (22, 42) includes an inlet (34) disposed outside the space and an outlet (36) disposed within the space adjacent the upper end such that low-density gas within the space can self-vent from the enclosure by passing out of the first passageway (20), drawing ambient air into the second passageway (22, 42). A generally horizontal section (30, 46) of the second passageway ext…
