Claims (1)

Теплообменная труба, профилированная сферическими лунками, расположенными рядами, отличающаяся тем, что, с целью интенсификации процесса теплообмена и снижения гидравлического сопротивления профилированной трубы в теплообменниках с опорными перегородками и винтообразным движением теплоносителя, сферические лунки с центрами сферы, расположенными вне плоскости, проходящей по внешней поверхности трубы, располагаются рядами вдоль оси трубы по всей ее длине с ориентацией в первом, четвертом, седьмом и т.д. рядах четырех лунок под углом β=90o одна к другой, во втором, пятом, восьмом и т.д. рядах трех лунок - под углом β=120o одна к другой, в третьем, шестом, девятом и т. д. рядах трех лунок - под углом β=120o одна к другой, но со сдвигом ориентации лунок данных рядов на 60° относительно лунок второго, пятого, восьмого и т. д. рядов, выполнена с геометрическими соотношениями 0,20 > hл/dл > 0,09; 20,5 > dл/hл > 1,80; 12,0 > S/dл > 1,33, где hл - глубина лунки, dл - диаметр лунки, d - внутренний диаметр трубы, S - шаг между центрами лунок вдоль оси трубы.A heat exchanger tube profiled by spherical dimples arranged in rows, characterized in that, in order to intensify the heat transfer process and reduce the hydraulic resistance of the profiled tube in heat exchangers with support baffles and screw-like motion of the heat carrier, spherical dimples with centers of a sphere located outside a plane passing along the outer surface pipes are arranged in rows along the axis of the pipe along its entire length with orientation in the first, fourth, seventh, etc. rows of four holes at an angle β = 90 o one to the other, in the second, fifth, eighth, etc. rows of three holes - at an angle β = 120 o one to another, in the third, sixth, ninth, etc. rows of three holes - at an angle β = 120 o one to another, but with a shift of the orientation of the holes of these rows by 60 ° relative to holes of the second, fifth, eighth, etc. rows, made with geometric ratios of 0.20> h l / d l >0.09;20.5> d l / h l >1.80;12.0> S / d l > 1.33, where h l is the depth of the hole, d l is the diameter of the hole, d is the inner diameter of the pipe, S is the step between the centers of the holes along the axis of the pipe.
