Abstract:
1. An equipment enclosure for use in an environment wherein a thermal conditioning system supplies thermally conditioned air, the equipment enclosure comprising: a body having an inner chamber and an outer plenum, the inner chamber forming part of a circulation path through which a fluid is circulatable in a closed loop within the enclosure, the outer plenum forming part of a flow path for the conditioned air through the enclosure; an enclosure door and a baffle having one or more apertures therethrough, each aperture sized to match a corresponding inlet in a piece of equipment, the baffle configured to define a mixing plenum of the fluid circulation path upstream of the inner chamber and adjacent the door; a pair of return ducts forming parts of the fluid circulation path outside the inner chamber to carry the fluid from downstream of the inner chamber to the mixing plenum; and a thermally conductive wall of the return ducts configured to separate the fluid circulation path from the conditioned air flow path through the outer plenum while functioning as a heat exchanger between the fluid and the conditioned air.
