Abstract:
A battery temperature stabilization system, comprising:a housing including at least one intake vent and at least one exhaust vent; a plurality of air passage ways for circulating air to an electronic equipment compartment and a battery compartment disposed in said housing, said battery compartment including at least one battery operable to provide backup power to circuitry disposed in said electronic equipment compartment; at least one heat exchanger unit operable for transferring heat from said electronic equipment compartment into a ductwork chamber forming a portion of said air passage ways; and a plurality of dampers controlling air flow through said air passage ways and said intake and exhaust vents, said dampers for routing air through said ductwork chamber in one of two directions, wherein ambient air drawn in is first heated by said heat exchanger before being directed to said battery compartment when said battery compartment's temperature is lower than ambient temperature, otherwise said ambient air is directed to flow in proximate contact with said battery compartment prior to receiving heat from said heat exchanger thereby cooling said battery compartment.
