По основному авт. св. № 143817 известен теплоо-бменный аппарат змееаикового типа, состо Щий лз Kopinyca и днищ, приварет ных к трубным решеткам, амеевиковых труб, навитых па сердечник и закрепленных в трубных решетках, «оторые соединены сердечником .According to the main author. St. No. 143817 is known for a heat exchanger apparatus of the snake type, consisting of a Kopinyca and bottoms welded to the tube grids, of the eyevik tube, wound on the core and fixed in the tube grids, which are connected by a core.

Цель изобретен и  - обеспечение надежноcTiH при работе апт1а:рата с большой разностью давлений теплообмениваюпщхс  сред.The goal was invented and - providing reliable cTiH when the APTa: ata works with a large pressure difference between heat exchange media.

Эта цель достигаетс  тем, что сердеч;пик озыполпен из .материала, имеющего коэффициент линейного расширени  больший, чем у материала корпуса, .)1апр,имер .из аустенитной стали .марки Х18Н10Т, а корнус из перл.итной стал.н MaipKH ВМСТЗСП.This goal is achieved by the fact that the heart has a peak from a material that has a linear expansion coefficient greater than that of the case material.) 1app, measured from austenitic steel X18H10T, and the corn starch from titanium steel.

На чертеже .изображена принципиальна  схема описываемого теплообмйнного .атепарата .In the drawing. Is a schematic diagram of the described heat transfer unit.

The post-stem is interconnected by means of a hollow core 4 on which the heat-insulated pipes 5 are fixed, fixed. in tube sheets. The core of VY | FULL. Of material having a linear expansion coefficient greater than that of material of the body is made of austenitic steel H18P10P, and the carnus of pearl-shaped steel V.1ZSPP. By pipe circ: kul:

ЕСЛИ диаметр аппарата довольно большой, то даже нри наличии укрепл ющего сер.дечни-ка толщина трубных решеток шрезышает ВОЗМОЖ.НОСТИ металлургических заводов, определ емые номенклатурой проката. Следовательно , сердечник используют не только как анкерную св зь, поддерживающую ирн натруженни анпарат в центральной части решетки, но .и как средство, сообщающее обратные проги|бы труб.ным решеткам в период нуска в эюаплуатад.ию аппарата, когда все его части охЛаждаютс  до рабочей темнературы.If the diameter of the apparatus is rather large, then even with the presence of reinforcing ser.dechni-ka thickness of the tube grids shreds POSSIBILITIES of the metallurgical plants, determined by the nomenclature of rolled products. Consequently, the core is used not only as an anchor link, supporting irn overloading the anapharat in the central part of the lattice, but also as a means of informing the reciprocal flow of the pipe during the start of the pipeline, in all devices that are cooled. working temperature.

(Return to the initial position. Consequently, the core is made of a material having a K01eff of linear expansion greater than that of the body material This makes it possible to significantly reduce the thickness of the pipe lattices of the nrn while simultaneously increasing the THICKNESS of the walls of the core.
