DEVICE FOR SPACE AEROSOL FIRE EXTINGUISHING Russian patent published in 2001 - IPC

FIELD: fire-extinguishing equipment, particularly, devices generating gas-aerosol fire inhibitors formed in burning of pyrotechnical composition and purposefully directed to protected space. SUBSTANCE: device has initiating unit, block of pyrotechnical composition installed with clearance in metal body provided with holes for communication with case circular channel closed with cover with discharge holes, heat exchanger and receiver. Novelty consists in that heat exchanger is made in the form of perforated shell external relative to body and fastened coaxially to pyrotechnical composition block in case through layer of gypsum plaster which is also filled into clearance between pyrotechnical composition block and body and combined with receiver, and communication holes on its side surface. Claimed device is more universal in use as it may be used additionally for manual fire extinguishing. EFFECT: higher functional reliability of device and efficiency of generating of fire inhibitors and increased efficiency of cooling of products of gas-aerosol fire-extinguishing mixture inside device. 2 dwg
