Abstract: Изобретение относится к области теплотехники, а конкретно к конструктивным элементам теплообменного оборудования различного назначения. Поверхность теплообмена содержит последовательно чередующиеся по направлению потока выступы. С целью интенсификации теплообмена, каждый выступ выполнен в виде четырехугольной призмы высотой h=(1,5-2)δ, где δ - толщина пограничного слоя потока. Одинаковые основания четырехугольной призмы выполнены в виде равнобедренной трапеции. Перпендикулярные основаниям четырехугольной призмы вихреобразующие ребра находятся на ее передней грани, проходящей через большую сторону равнобедренной трапеции размером b, обращенную навстречу потоку и перпендикулярную направлению потока. Задняя грань четырехугольной призмы, проходящая через меньшую сторону равнобедренной трапеции, параллельную большей стороне равнобедренной трапеции, имеет размер ƒ=(0,2-0,5)b. Четырехугольные призмы расположены в шахматном порядке с шагом ƒ между вихреобразующими ребрами соседних четырехугольных призм, расположенных перпендикулярно направлению потока, и для обеспечения интенсивного вихреобразования с шагом S=(12-14)h между передними гранями соседних четырехугольных призм, расположенных по направлению потока. Технический результат - повышение эффективности теплообмена между потоком и поверхностью за счет интенсивного вихреобразования в пограничном слое потока. 2 ил.
