A thermal aerosol fire extinguishing device for small space powered equipment

Abstract

The utility model discloses a hot aerosol fire extinguishing device for small space power supply equipment, including shell, sealing gasket and apron, the apron sets up at one side of shell, and the sealing gasket sets up between shell and apron, the sidewall on shell bottom has a plurality of spouts, be equipped with the cartridge and cooling frame in the shell, the utility model discloses a vortex cooling channel is formed with sealing gasket and cooling frame, and the mixed gas of the burning of the medicine column generates the strong vortex and turbulence when flowing along the vortex cooling channel, greatly increase its contact area and contact time with the cooling wall surface, to strengthen heat transfer, accelerate cooling, make the final formation's fire extinguishing microparticle size smaller and distribute evenly, these small size aerosol particle diffusion speed is fast, is not easy to be blocked by component, more easily diffuses to the burning point in the component gap deep place and carries out the fire extinguishing, to promote the fire extinguishing efficiency of hot aerosol fire extinguishing device in small space power supply equipment.
