Abstract

A modular door mounted heat exchanger (10) for use with an outdoor equipment enclosure (12) of the type having a sealed equipment compartment (22) used to house heat generating electronics and telecommunications equipment (29) therein is disclosed. The heat exchanger includes a door panel (33) sized and shaped to be received on, and to close an access opening (20) defined as a part of the equipment enclosure. The door panel has an interior surface (34) for facing inwardly of the enclosure, and an exterior surface (36) for facing outwardly of the enclosure. A heat exchanger cover (37) constructed and arranged to be mounted to the exterior surface of the door panel is provided. The heat exchanger cover defines a plenum (38) between the exterior surface of the door panel and the heat exchanger cover. At least a first opening (40) and at least a spaced second opening (41) are defined within the plenum for defining an air flow path (44, 45) passing within and at least partially along the plenum. At least one fan (42, 48, 79) is provided for drawing air into and exhausting air out of the plenum through the at least first and second openings, respectively. The fan is constructed and arranged to draw outside air through the plenum for cooling the exterior surface of the door panel, so that the air within the enclosure that comes into contact with the interior surface of the door panel is in turn cooled.

Claims

1. A modular door mounted heat exchanger for use with an outdoor equipment enclosure of the type used to house electronics and telecommunications equipment, the enclosure being provided with an access opening for allowing access to the equipment housed therein, said heat exchanger comprising:

a door panel sized and shaped to be received on and to close the access opening of the enclosure, said door panel having an interior surface for facing inwardly of the enclosure, and an exterior surface for facing outwardly of the enclosure;

a heat exchanger cover constructed and arranged to be mounted to the exterior surface of said door panel, said heat exchanger cover defining a plenum between the exterior surface of the door panel and the heat exchanger cover;

at least a first opening into said plenum and at least a spaced second opening into said plenum for defining an air flow path within and at least partially along said plenum; and

at least one fan operably coupled to said door panel and being constructed and arranged to draw air into and exhaust air out of said plenum through said at least first and second openings, respectively;

whereby outside air drawn through the plenum by the at least one door mounted fan cools the exterior surface of the door panel so that the air within the enclosure that comes into contact with the interior surface of the door panel is cooled.

2. The heat exchanger of claim 1, wherein said heat exchanger cover is constructed and arranged to be removably fastened to said door panel.

3. The heat exchanger of claim 1, wherein said at least one fan is mounted on the interior surface of said door panel.

4. The heat exchanger of claim 1, wherein said at least one fan is mounted within the equipment enclosure.

5. The heat exchanger of claim 1, wherein said at least one fan is mounted within the plenum of said heat exchanger.

6. The heat exchanger of claim 1, wherein said at least a first opening is defined in said door panel and said at least a second opening is defined in said heat exchanger cover.

7. The heat exchanger of claim 1, wherein each of said at least a first and second openings, respectively, is defined in said heat exchanger cover.

8. The heat exchanger of claim 1, further comprising a spaced series of fins on said door panel, each said fin projecting away from the interior surface of the door panel and also projecting away from the exterior surface of the door panel and into the plenum of the heat exchanger.

9. The heat exchanger of claim 1, said door panel being sized and shaped as a convolute door panel.

10. The heat exchanger of claim 1, further comprising an elongate duct along the interior surface of the door panel, said duct being sized and shaped to channel air within the enclosure into engagement with the interior surface of the door panel.

11. The heat exchanger of claim 10, further comprising at least a second fan for directing air within the enclosure into said duct.

12. The heat exchanger of claim 11, said at least a second fan being mounted to said door panel.

13. A modular door mounted heat exchanger for use with an outdoor equipment enclosure, the equipment enclosure including a first electronics compartment for housing heat generating electronics and telecommunications equipment therein and a separate second battery compartment for housing at least one battery therein, the enclosure defining a common access opening for allowing access into both of the electronics and battery compartments of the enclosure, said heat exchanger comprising:

a door panel sized and shaped to be received on and to close the access opening of the enclosure, said door panel having an interior surface facing inwardly of the enclosure, and an exterior surface facing outwardly of the enclosure;

a heat exchanger cover constructed and arranged to be mounted to the exterior surface of said door panel, said heat exchanger cover defining a plenum therebetween in cooperation with said door panel;

at least a first opening defined in said door panel juxtapositioned with the battery compartment of the enclosure, and at least a spaced second opening defined in the heat exchanger cover for defining an air flow path within the plenum between the exterior surface of the door panel and the heat exchanger cover; and

at least one fan operably coupled to said door panel and being constructed and arranged to draw outside air through both of the battery compartment and the plenum for cooling the battery compartment of the enclosure, and for cooling the exterior surface of the door panel so that air within the enclosure that comes into contact with the interior surface of the door panel is cooled thereby.

14. The heat exchanger of claim 13, wherein said at least one fan is constructed and arranged to draw outside air into the plenum through the at least a first opening in the door panel and to exhaust the outside air from the plenum through the at least a second opening in the heat exchanger cover.

15. The heat exchanger of claim 13, wherein said at least one fan is constructed and arranged to draw outside air into the plenum through said at least a second opening in the heat exchanger cover and to exhaust the outside air from the plenum through the at least a first opening in the door panel.

16. The heat exchanger of claim 13, wherein said at least one fan is mounted on the interior surface of said door panel.

17. The heat exchanger of claim 13, wherein said at least one fan is mounted within the interior of the equipment enclosure.
