FIRE SUPPRESSION SYSTEMS AND METHODS OF SUPPRESSING A FIRE
First Claim
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; and
a second pressure-sensitive barrier covering the one or more second openings.

Abstract
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.

10. A fire suppression system, comprising:
-
a generator housing having a solid gas generant material and an ignition material disposed therein; and a cooling system coupled to the generator housing, the cooling system comprising; a first, outer housing at least partially defining a first chamber therein; a second housing at least partially defining a second chamber therein, the second housing positioned generally centrally within the first chamber; a coolant material disposed within the first chamber and at least partially surrounding the second housing; a first barrier covering one or more first openings into the first chamber positioned and sized to provide fluid communication to the first chamber from the generator housing; and a second barrier covering one or more second openings positioned and sized to provide fluid communication between the first chamber and the second chamber. - View Dependent Claims (11, 12, 13)

14. A method of suppressing a fire, the method comprising:
-
generating a fire suppressant gas with a gas generant material disposed in a generator housing; directing the generated gas to a cooling system disposed adjacent to the generator housing; rupturing, responsive to pressure from the generated gas, a first pressure-sensitive barrier covering one or more first openings into a first longitudinal end of a first chamber of the cooling system; directing a portion of the generated gas into the first chamber though the one or more first openings; rupturing, responsive to pressure from the generated gas acting on a coolant material in the first chamber, a second pressure-sensitive barrier covering one or more second openings between a second longitudinal end of the first chamber and a second chamber of the cooling system at least partially surrounded by the first chamber; and directing at least a portion of the coolant material from the first chamber to the second chamber through the one or more second openings. - View Dependent Claims (15, 16, 17, 18, 19, 20)
