Patent ID: 7845423

Claim:
A fire suppression apparatus comprising: a structure having a first inlet opening therein, a second outlet opening therein and a flow path providing fluid communication between the first inlet opening and the second outlet opening; a gas-generating device located and configured to provide a flow of a first gas through a nozzle of the gas-generating device, the nozzle extending into and at least partially surrounded by a portion of the flow path, and to direct the flow of the first gas out of the nozzle into the flow path downstream from the nozzle such that the flow of the first gas draws a volume of a second gas through the first inlet opening and into the flow path upstream from the nozzle; a diffuser in the flow path downstream of the nozzle, the diffuser located and configured to effect mixing of the first gas with the volume of the second gas drawn into the flow path to form a gas mixture and to expand the gas mixture to reduce a velocity and a temperature of the gas mixture; and a heat transfer device disposed in the flow path between the diffuser and the first inlet opening and configured to allow at least the second gas therepast.
