Abstract

An outdoor equipment cabinet enclosure designed to effectively dissipate heat generated by electrical equipment components housed therein includes a main interior section for housing active electronic components and a lower section configured to store banks of batteries for a stand-by power supply system with a lower wall separating the batteries from the electronic components in the main interior section. At least one heat exchanger is disposed in the main interior section and includes an inlet port and means for creating a circulating air flow path for interior air within the main interior section. An outdoor air flow path is defined by the lower wall and the upper surfaces of the batteries and at least one baffle is disposed within the outdoor air flow path which is configured to deflect outdoor air flowing across the upper surfaces of the batteries into the at least one heat exchanger. The at least one baffle is disposed at an acute angle to the upper surfaces of the batteries from a point adjacent inwardly disposed sides of the batteries.

Claims

1. An outdoor equipment cabinet enclosure comprising:

a main interior section defined by side walls, a lower wall and a roof for housing active electronic components;

a lower section of said enclosure configured to store banks of batteries for a standby power supply system wherein said lower wall separates said batteries from said electronic components;

at least one heat exchanger disposed centrally of said main interior section and extending vertically between said lower wall and said roof, said heat exchanger including an inlet port and means for creating a circulating air flow path for interior air within the main interior section;

an outdoor air flow path defined by said lower wall and upper surfaces of said batteries; and

at least one baffle disposed within the outdoor air flow path and configured to deflect outdoor air flowing across upper surfaces of the batteries and into the at least one heat exchanger, said at least one baffle being disposed at an acute angle to the upper surfaces of the batteries from a point adjacent inwardly disposed sides of the batteries.

2. The enclosure of claim 1 including a fan disposed within the interior column of the at least one heat exchanger.

3. The enclosure of claim 1 including an exhaust air flow path within the roof, the enclosure configured to exhaust air from the interior column of the heat exchanger to at least one edge of the roof.

4. The enclosure of claim 1 including a pair of baffles disposed adjacent one another and facing in opposite directions.

5. The enclosure of claim 1 including a plurality of heat exchangers spaced from one another along the length of the enclosure.

6. The enclosure of claim 1 wherein said at least one baffle is disposed at an angle of in a range of twenty-five to forty degrees from a plane including upper surfaces of said batteries.

7. The enclosure of claim 1 wherein said at least one baffle includes an upwardly directed portion and an angled portion defining a bend and said bend is disposed proximate rear upper edges of said batteries to retain said batteries within said cabinet.

8. The enclosure of claim 1 including at least one diverter disposed within said outdoor air flow path for diverting outdoor air through spaces between said batteries.

9. The enclosure of claim 8 wherein said at least one diverter is configured as an upwardly open channel to thereby serve as a cable trough.
