Целью изобретени вл етс повышение эксплуатационной надежности и технологичностиоThe aim of the invention is to improve the operational reliability and manufacturability.
1Ы чертеж изображен предлагаемый кожухотрубный теплообменникеFigure 1 shows the proposed shell-and-tube heat exchanger.
Теплообменник содержит кожух, состо щий из двух частей 1 и 2 одинаковой длины и размещенный внутри кожуха пучок теплообменных труб 3, закрепленных в трубных досках 4 и 5. На каждой части кожуха выполнены винтовые гофры 6 и 7,служащие компенсатором температурных удлинений. Гофры 6 и 7 направлены противоположно один другому под одинаковым углом (угол of равен углу Л ) к плоскости стыка частей кожуха.The heat exchanger contains a casing consisting of two parts 1 and 2 of the same length and a bundle of heat exchange tubes 3 placed inside the casing fixed in tube plates 4 and 5. On each part of the casing there are screw corrugations 6 and 7 serving as a compensator for temperature extensions. The corrugations 6 and 7 are opposite to each other at the same angle (the angle of is equal to the angle L) to the plane of the junction of the housing parts.
При возникновении температурных напр жений в процессе работы теплообменника благодар разному направлению винтовых гофр 6 и 7 частей 1 и 2 кожуха среднее сечение кожуха в зоне стыка будет поворачиватьс At the occurrence of temperature stresses in the process of operation of the heat exchanger due to the different direction of the screw corrugations 6 and 7 of parts 1 and 2 of the casing, the average cross section of the casing in the joint zone will rotate
вокруг оси, обеспе ива при зтом компенсацию температурных удлинений и предотвращение скручивани теплообменных труб.around the axis, providing at the same time compensation for temperature lengthening and prevention of twisting of heat exchange tubes.
Использование изобретени позвол ет повысить эксплуатационную надежность теплообменников, а также упростить технологию их изготовлени .The use of the invention allows to increase the operational reliability of heat exchangers, as well as to simplify the technology of their manufacture.
