FIRE PROTECTION Russian patent published in 2020 - IPC A62C2/06 

FIELD: heat protection structures.

SUBSTANCE: invention relates to the field of creation of heat-shielding structures for protection against fire and explosive dangerous goods (items) from long-term fire, packages, metal cabinets, safes with material values, important documents, money and other similar protection objects during their storage and transportation. Fire protection comprises a casing in the form of an elongated metal container with a filler in form of a working medium with a boiling point below the critical temperature of the protected object, jet nozzles for boiling filler steam outlet, metal plates are arranged inside the vessel, from outside the casing at least on one side there made is ribbing from metal plates installed opposite to internal plates, which are connected to opposite walls of the container in staggered order, forming a zigzag channel filled with working substance in upper part of the casing there is a receiver, consisting of additional capacity and (or) pipes coming from opposite sides of the casing and made in the form of interconnected loop siphons, which ends are tightly connected to each other, and to them in turn are connected evaporating tubes with nozzles for steam output, wherein evaporation tubes are arranged on at least one side of jacket and are fixed on plates of its outer finning, and their ends are hermetically sealed. One of the pipes of the loop siphon has S-shaped two-loop siphon shape, and the second pipe coming from the opposite side of the casing has at least one-loop U-shaped siphon shape.

EFFECT: improved manufacturability of fire protection due to simplification of its design.
