Description
Известно оребрение дл теплообменной трубы , .вынолненное в виде привареппы.к к ней продольных металлических нолос с нонеречными надрезами. Такое оребренне может быть нспользовано только при продольном смывании труб потоком с относительно низкой скоростью.A fin is known for a heat exchange tube, made in the form of a welded pipe. To it are longitudinal metallic nolos with non-pointed cuts. Such finning can not be used only when longitudinal flushing of pipes with a stream at a relatively low speed.
Цель изобретени - уменьшить трудозатраты при получении поперечных ребер нз продольно приваренных к трубе нолос.The purpose of the invention is to reduce labor costs in obtaining transverse ribs nz longitudinally welded to the pipe nolos.
Это достигаетс тем, что отрезки полос между надрезами изогнуты с поворотом относительно своих осей в положение, перпендикул рное НЛОСКОСТИ НОЛОСЫ.This is achieved by the fact that the segments of the strips between the incisions are curved with rotation relative to their axes to a position perpendicular to the NOSE of the NOLOS.
На фиг. 1 схематнчески ноказана последовательность онерацнй дл нолучени полеречных ребер; на фиг. 2 - труба с понеречпымн ребрамн, продольный разрез.FIG. 1 schematically shows the sequence of the sequence to obtain polierechny ribs; in fig. 2 - pipe with Ponerechpymn rib, longitudinal section.
На металлической полосе / делают поперечные надрезы 2. Дл нолучени ноперечных On the metal strip / make transverse incisions 2. For getting transverse
ребер 5 отрезкн полосы меладу надрезами изгибают с поворотом отпосительно своих осей в положепие, нернендикул рное плоскости полосы.the ribs 5 of the cut-off strip meladu bends with rotation, with respect to their axes, to a positon that is alternate to the plane of the strip.
Основание 4 нолосы подгибают и приваривают к трубе 5 продольным швом.The base 4 nolosy bend and weld to the pipe 5 with a longitudinal seam.
Предмет изобретени Subject invention
Оребрение дл тенлообменной трубы, вынолненное в внде приваренных к ней продольных металлических нолос с поперечными надрезами , отличающеес тем, что, с нелью уменьшени трудозатрат при получении поперечных ребер, отрезкн нолос между надрезами изогнуты с поворотом относительно свонх осей в нололсенне, перпендикул рное плоскости нолосы.The fins for the tenlo exchange tube, made of longitudinal metal nolos with transverse cuts welded to it, are characterized in that, in order to reduce labor costs in obtaining transverse ribs, the nolos between the cuts are bent with rotation relative to their axes in nololsen, perpendicular to the plane of the nolos
