FIELD: fire safety.SUBSTANCE: invention relates to fire-fighting equipment, particularly hand-held fire extinguishing aerosol generators. Device for 3D fire fighting includes coaxially fixed with injection gap, cooling cylinder and housing with heat-protective layers inside. Housing is closed by cover with distributed outlets, under which, through receiver, functional pyrotechnic cartridge of end burning and electric spark igniter of external initiation are fixed. According to invention, pyrotechnic cartridge is made with central channel, where through armoring coat congruently adjoined communication metal tube of receiver, limited by disk convector of communication tube, with combustion chamber under functional cartridge formed by metal bottom, in which electric igniter is mounted; cover rests on posts of disk convector and cooling cylinder is arranged on body with partial overlapping by means of radial pylons of stepped shape.EFFECT: invention provides effective cooling of generated aerosol within device due to separation of high-temperature phase on metal bottom and reversing its flow in labyrinth convector with developed heat dissipation surface.2 cl, 1 dwg |
