Источники информации .прин тые во внимание при экспертизе; 1, Авторское свидетельство СССР № 250923. кл, F 28 D 9/О2, 1968,(-54) SHELL-TUBE HEAT EXCHANGER are equipped with a cylindrical tube; 3 for another heat carrier; fixed in the tube plate 4, the tubes 3 are made and -shaped, and the plate 4 has a cavity 5 communicated with the annular space 6, the plate 4 is equipped with an outlet nozzle 7 with a leak detector (not shown) . Spacers 8 are located between the flat pipes 2 along their perimeter, repeating the shape of the pipes. Above the tube plate there are collectors 9 and 10, respectively for the supply and removal of air from the pipes 3, and a pipe 11 for supplying fuel to the pipes 2 and a pipe 12 for its removal are fixed on the housing. The flat pipes 2 in the upper part are hooked to the tube plate 4 and have first slot 13 on the side surface, and corrugated plates 14 are placed inside the tube. The heat exchanger works as follows, Heat from one heat carrier Burned air) through walls U -shaped cylindrical tube 3 and flat tube 2 is transferred to another coolant circulating inside the flat tubes (fuel} "in the event of depressurization of one of the planes, the coolant not subject to mixing, enters the annular space 6 (buffer © zone ) and from there it is guided by the hydraulically connected internal cavity 5 of the tube board 4e. The pressure in the annular space (buffer zone) is changed and the pressure signal is released from the depressurization and the possibility of a hazardous situation arising at the indicator; the magnitude of the pressure is carried out to determine the nature of the destruction. To prevent the formation of a nasal-explosive mixture in the event of a depressurization of the inventory from the coolant cavities, the annular space is filled with a neutral The main principle of the invention is the high reliability and safety of the heat exchanger due to the sealing of the annular space and the possibility of obtaining a timely signal of depressurization of one of the pipe cavities. , because. heat transfer is carried out directly through the walls of pipes whose thermal resistance, as Ost. n known. --- Formula of the invention Shell-and-tube heat exchanger with a buffer zone, containing a river. Flat tubes placed in the shell for one heat carrier and hermetically connected to them, sealed in a tube plate of a cylinder. Heat pipes for another heat carrier. that, in order to improve the efficiency by preventing the mixing of coolants during the expansion of your pipe polooTotj, cylindrical pipes are made (J-shaped, and the board in which they are fixed is hollow and communicated with the annular space, and the board is equipped with an outflow pipe and the sigHaffiiaa TopoM leakage, and between adjacent flat pipes, deliveries are set up according to their perimeter, which repeat the shape of cylindrical pipes.
