FIRE SUPPRESSION SYSTEMS AND METHODS OF SUPPRESSING A FIRE

摘要

Fire suppression apparatuses include a housing with gas generant material disposed therein, an initiator for igniting the gas generant material, and a cooling system. The cooling system includes a first chamber with a coolant material disposed therein and a second chamber. The coolant material is caused to flow from the first chamber into the second chamber to cool gas formed by the ignition of the gas generant material upon exiting from the housing under pressure. The cooling system may further include a piston disposed within the first chamber and movable responsive to gas pressure. Methods for cooling a fire suppressant gas and methods for suppressing a fire include flowing a fire suppressant gas into first and second chambers of a cooling system, flowing a coolant material from the first chamber into the second chamber, and contacting the fire suppressant gas with the coolant material to cool the fire suppressant gas.

主权项

1. A fire suppression system, comprising:
a generator housing having a gas generant material disposed therein; and a cooling system disposed adjacent to the generator housing, the cooling system comprising:
a first chamber having a coolant material disposed therein;a second chamber at least partially laterally surrounded by the first chamber;one or more first openings into a first longitudinal end of the first chamber;a first pressure-sensitive barrier covering the one or more first openings;one or more second openings between a second longitudinal end of the first chamber and the second chamber; anda second pressure-sensitive barrier covering the one or more second openings.
