Fireproof cabinet system for electronic equipment

A system for protecting electronic equipment and maintaining its continuous function during an external fire in a room area surrounding said equipment, comprising:

• a fire resistant and waterproof wall shield enclosure for enclosing said equipment, said wall shield enclosure including an outer metal layer having a high thermal conductivity and providing a radiation shield, an adjacent support layer having a low thermal conductivity and high mechanical strength, and an inner wall duct means extending along the support layer on the inside of said wall shield means for passage of a gas coolant adjacent said wall shield enclosure for cooling said wall shield;
• water supply means for continuously providing coolant water on substantially the entire outside surfaces of said outer metal layer of said wall shield enclosure to remove heat therefrom and preventing fire damage to said wall shield enclosure;
• forced gas cooling means for providing coolant gas from outside said wall shield enclosure into said inner wall duct means of said wall shield enclosure for cooling an interior thereof and also removing heat received from said outer metal layer, said forced gas cooling means including a coolant gas supply, an intake duct means leading from said coolant gas supply into the interior of said wall shield enclosure, and exhaust duct means for removing heated air from said inner wall duct means to the outside of said wall shield enclosure;
• and
• control means responsive to the detection of a fire condition in said room area for activating said water supply means;
• whereby said coolant gas in combination with said continuous coolant water on said outer metal layer act to decrease the heating effects of fire on said wall shield enclosure and remove heat from the interior thereof to maintain said electronic equipment in operation at a desired temperature and air quality.
