Abstract
Использование в теплообменниках и конденсаторах паровых турбин. Сущность изобретени : труба 1 содержит размещенную по ее оси ленточную вставку 2, примыкающую к внутренней поверхности трубы и имеющую чередующиес спиральные 3 и пр молинейные 4 участки, причем последние со стороны, примыкающей к одному из спиральных участков 3, имеют периферийные вырезы, длина которых не превышает половины шага спирального участка. Вырезы могут иметь одинаковую ширину или уменьшающуюс по ее длине, при этом максимальную величину вырезы имеют в сечении , примыкающем к спиральному участку. В поперечном сечении трубы вырезы могут иметь переменную ширину, уменьшающуюс в направлении закрутки ленты, или отогнутые в том же направлении лепестки. 4 з.п. ф-лы, 4 ил.Use in heat exchangers and steam turbine condensers. SUMMARY OF THE INVENTION: Tube 1 comprises a tape insert 2 placed along its axis, adjacent to the inner surface of the pipe and having alternating spiral 3 and straight 4 sections, the latter having peripheral notches on the side adjacent to one of the spiral sections 3. exceeds half the pitch of the spiral section. The cuts can have the same width or decrease along its length, with the maximum size of the cuts having a cross section adjacent to the spiral section. In the cross section of the pipe, the cutouts may have a variable width, decreasing in the direction of twist of the tape, or petals bent in the same direction. 4 hp f-ly, 4 ill.
