An outdoor battery cabinet is formed to include a cooling system to extend the life of the housed batteries. The cooling system comprises a ventilation system including an air intake unit, an exhaust unit and a thermostat control. The interior surface of the cabinet is covered with a layer of insulative material. The ventilation system is configured to turn 'on' when the outdoor temperature drops below the interior cabinet temperature, thereby cooling the housed batteries. Once the outdoor temperature rises above the cabinet temperature, the ventilation system is turned 'off' and the insulation in the cabinet functions to maintain the cooler ambient temperature within the cabinet. To minimize the effects of wind forcing air through the ventilation openings, the intake and exhaust louvers are located on the same side of the cabinet.

Cooling system for stand-alone battery cabinets

An electronics cabinet which provides venting of gases within a battery compartment and also protects the inside from wind driven rain and other particles. A cover assembly is provided over the compartment of the cabinet, which assembly includes a cover member with a plurality of louvers and a blocking plate covering the louvers. A fan is mounted in the compartment in order to circulate air within the compartment so as to enhance the venting capability.

Electronic cabinet with vent

For cooling cabinets housing electrical equipment, fans are used for pulling internal air upwardly through the electronic equipment into a common space beneath the roof of the cabinet. Baffles within the space distribute the heated air in desired patterns across the inside roof surface and to ducts mounted on interior surfaces of external vertical walls of the cabinet for cooling the air by heat exchange through the roof surface and the vertical cabinet walls. In a second arrangement, an attic-like structure having a thermally insulated roof is mounted on the cabinet roof. External air is blown through the attic-like structure and across the cabinet roof for enhanced cooling of cabinet-heated air beneath the cabinet roof.

Electrical equipment cabinet cooling

Disclosed is an apparatus for cooling unvented cabinets housing electronic equipment. A fanning unit at a bottom portion of the cabinet draws air down through the spaces between printed circuit boards which include the electronic components. A plate installed on the inside of the cabinet door creates a duct to cause cooling of the air at the door surface as it flows upward for recirculation. A heat exchange element may also be provided in the space between the equipment mounted on both sides of the cabinet.
