Abstract
An equipment cabinet mounted on a concrete pad. The cabinet includes an upper equipment chamber, a lower back-up battery chamber and a heat exchanger. Ambient air is drawn across batteries in the lower chamber before being drawn into the heat exchanger to help cool electronic components in the upper chamber. Air in the upper chamber is separate circulated through the heat exchanger. A cold plate is placed beneath the batteries and is connected to a refrigeration system. A heating pad is located below the cold plate and is separated from the concrete pad by insulation. The cold plate and the heating pad are used to maintain the batteries at about 25° C. regardless of ambient temperatures so as to extend the useful lives of the batteries.
