Cooling enclosure for maintaining commercial-off-the-shelf (COTS) equipment in vehicles
First Claim
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.

Abstract
Apparatus and methods for thermal conditioning equipment. In a preferred embodiment, an equipment enclosure comprises a body, a wall, a fluid port, and a fixture. The body defines an outer plenum and an inner chamber in the latter of which the fixture retains the equipment. The wall, which is between the outer plenum and the inner chamber, isolates the thermally conditioned first fluid from a second fluid in the inner chamber. Since the wall is thermally conductive it allows heat to be transferred between the outer plenum and the inner chamber. The fluid port is in communication with the outer plenum to allow the thermally conditioned first fluid to flow into the outer plenum. Baffle plates are also provided to distribute flow of the second fluid to the equipment.

14. A method of thermally conditioning equipment in an environment where a thermal conditioning system supplies thermally conditioned air, the method comprising:
-
enclosing one or more pieces of equipment in an inner chamber of an enclosure, the enclosure having a flow path for the conditioned air and a circulation path for a fluid, the fluid circulation path including the inner chamber, a pair of return ducts downstream of the inner chamber, and a mixing plenum downstream of the return ducts, the mixing plenum formed between a door of the enclosure and a substantially vertical baffle directing substantially horizontal entry of the fluid through one or more apertures of the baffle into one or more inlets in the equipment in the inner chamber, the one or more apertures aligned with the one or more inlets, the conditioned air flow path including an outer plenum of the enclosure, the outer plenum adjacent to the return ducts; circulating the fluid in a closed loop through the mixing plenum, inner chamber and return ducts to exchange heat between the equipment and the fluid; and substantially vertically circulating the conditioned air upwardly through a first portion of the outer plenum and downwardly through a second portion of the outer plenum and past a thermally conductive wall of the return ducts to exchange heat through the wall between the fluid and the conditioned air in the outer plenum. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)

23. 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 at least partially surrounding the inner chamber, the 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; a front door of the enclosure and a baffle facing the door at a front of the inner chamber, the door and baffle defining a mixing plenum of the fluid circulation path upstream of the inner chamber, the baffle having one or more apertures configured to direct the fluid from the mixing plenum into one or more corresponding equipment inlets while the baffle restricts the fluid from flowing elsewhere in the inner chamber; an exhaust plenum in the body rearward of the inner chamber; one or more fans configured to circulate the fluid from the exhaust plenum to the mixing plenum; one or more return ducts in the fluid circulation path outside the inner chamber to carry the fluid circulated through the exhaust plenum to the mixing plenum; and a thermally conductive wall of the one or more return ducts that separates 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.
