FIRE PROTECTION DEVICE Russian patent published in 2007 - IPC A62C2/06 E05G1/00 

FIELD: fire fighting, particularly creation of thermal protection structures adapted to protect different objects against fire.

SUBSTANCE: fire protection device includes case made as elongated metal vessel filled with capsulated filler. Each capsule is sealed shell made of heat-conductive material and including receiving pipe crossing the shell so that pipe axis coincides with geometrical shell center. Filler is arranged in space between the shell and the pipe. The filler is working agent having boiling temperature below critical temperature of object to be protected. At least one jet is formed in pipe wall so that jet axis passes through geometrical shell center. The jets are communicated with orifices made in elongated metal vessel. Elongated metal vessel and jets may have any cross-section. Vessel orifices are closed with technological caps or material having low melting point. Working agent is selected from two and/or more components having different transition points, which are initially in the same or different phase conditions, for instance in liquid and solid states. Vessel surface may be polished or made as mirror surface.

EFFECT: increased difference between ambient temperature and object temperature during long-term object to be protected exposing to heat and during object cooling, decreased device mass and size, as well as increased device resistance to tilting and mechanical damage.
