<p>An electrical equipment cabinet is provided to contain heat-generating electrical equipment. The cabinet includes an enclosure having at least one access opening and a door providing a closure for the access opening. When open, the door permits access to the electrical equipment and when closed maintains a substantially closed environment in the interior of the cabinet. An air-to-air crossflow heat exchanger is removably engaged with and supported by the door for removing heat from the interior of the cabinet while maintaining the substantially closed environment within the cabinet. The heat exchanger defines a first air flow path for air drawn from the exterior of the cabinet and a second air flow path for air drawn from the interior of the cabinet. The first and second air flow paths are perpendicular to, and substantially isolated from, one another. A fan is mounted in an interior region of the door for circulating air through at least one of the first and second air flow paths.</p> |
