Abstract
A purge system develops a positive pressure in an enclosure, with sufficient volumetric air flow to cool the electrical components. The system includes an air inlet hose, with the input into the inlet hose positioned in an unclassified (i.e. safe) area. The inlet hose couples to the suction of an air blower, which may be mounted inside or outside the enclosure, while the discharge of the air blower is inside the enclosure, thereby providing the necessary positive pressure (purge) within the enclosure. The air discharged from the air blower strikes a baffle, which distributes the blowing air throughout the bottom of the enclosure. The distributed air is then drawn into controller cabinets by dedicated cooling fans. A conduit system connects the controller cabinets to take the now heated air from the cabinets to a discharge outside the enclosure. The outlet of the conduit system may include a counter-weighted flapper valve to maintain the pressure within the enclosure.
