AUTOMATIC FIRE EXTINGUISHING AEROSOL GENERATOR Russian patent published in 2017 - IPC A62C13/00 

FIELD: fire safety.

SUBSTANCE: automatic fire extinguishing aerosol generator comprises an axial tubular heat exchanger and cylindrical body inside of which through thermally insulated layer an end burning pyrotechnic stick is set in a localized combustion chamber communicating with the cover outlet openings and the tubular heat exchanger and external initiation igniter. Combustion chamber and a heat exchanger are interconnected directly through the expansion pre-chamber above an additional casing, in which a pyrotechnic stick is fixed by gypsum plaster layer and the ends of fixed in the casing tubular heat exchanger are equipped with air distribution grates, the upper of which is switched through the receiver with the outlet cover openings, and the igniter is provided with a self-contained initiating device - thermochemical cord, and heat exchanger tubes are made of aluminium, copper or steel.

EFFECT: multi-stage cooling in a compact functional aerosol generator, thereby increasing the efficiency of fire-fighting.
