Patent ID: 7778013

Claim:
An electrical enclosure venting system comprising: an enclosure having at least one vertically oriented door directly between an interior volume of the enclosure and an external environment, the enclosure being configured to house electrical components capable of generating hot gases during an arc-fault, wherein the vertically oriented door is substantially perpendicular to sidewalls of the enclosure; and a baffle disposed over an opening in the vertically oriented door directly into the interior volume of the enclosure in which the electrical components are disposed, the baffle including gas deflecting surfaces configured to deflect the hot gases from the interior volume of the enclosure directly to the external environment via the opening in the vertically oriented door and to cool the hot gases during their transport from the interior volume of the enclosure to the external environment, wherein the baffle includes a plurality of parallel deflecting elements in overlapping arrangement, wherein the deflecting elements interrupt all direct transport paths of hot gases between the interior of the enclosure and the external environment, and wherein the deflecting elements comprise inverted V or chevron shaped structures.
