FIELD: power engineering.SUBSTANCE: invention relates to the field of heat engineering and may be used in cryogenic equipment for evaporation of gaseous media, in space rocket engineering, etc. A tract of cryogenic component supply includes at least two double-layer shells, an inner and an outer ones, forming a circular cavity for passage of heating coolant. Each shell comprises two rigidly connected shells. At the inlet to the circular cavity there is a cover fixed, where mixing elements are installed, and an ignition device, and at the outlet there is a gas duct. The tract is made as profiled, and comprises a cylindrical part and a narrowing part in the form of a confusor, to form a circular cavity with channels for passage of the cryogenic component between the specified parts. Ribs forming channels for passage of the cryogenic component in the inner shell are made on the inner surface of the cylindrical part of the outer shell, at the same time on the narrowing part of the shell the specified ribs are made on the outer surface of the inner narrowing part of the shell. Inside the conical part there is a nozzle, connected to the cavity of the inner shell, and headers of cryogenic component supply and drainage in the inner cavity of the external shell are located on the specified narrowing part of the external shell.EFFECT: invention is aimed at simplification of design and assembly, reduced dimensions and weight of a cryogenic liquid evaporator.3 dwg |
