Description

Изобретение относитс к теплообменной аппаратуре и может быть использовано в энергетической промышленности.The invention relates to heat exchange apparatus and can be used in the energy industry.
Известен способ изготовлени теплообменной трубы из гладкостенной цилиндрической зато- товки путем оребрени ее наружной поверхности и размещени внутри нее вдоль .оси сердечника с про дольно-радиальными ребрами 1.A known method of manufacturing a heat exchange tube from a smooth-walled cylindrical sharpening is by finning its outer surface and placing inside it along the axis of the core with longitudinal radial ribs 1.
Недостатком указанного способа вл етс усложненность процесса наружного оребрени трубы и необходимость дополнительной обработки ее внутренней поверхности под установку сердечника.The disadvantage of this method is the complexity of the process of external finning of the pipe and the need for additional processing of its internal surface for the installation of the core.
Цель изобретени - повышение технологичности .The purpose of the invention is to improve manufacturability.
Это достигаетс тем, что предварительно внутрь заготовки устанавливают сердечник, после чего на наружной поверхности ее формируют оребрение с одновременным обжатием до внутреннего диаметра, меньшего диаметра вершин ребер сердечника, и придает заготовке форму многоугольника в поперечном сечении, вершины которого соответствуют ребрам сердечника , частично вдавленным в стенку заготовки .This is achieved by pre-inserting the core into the core, after which the fins are formed on its outer surface with simultaneous compression to the inner diameter, smaller diameter of the core edges, and the shape of the polygon in cross-section, the tops of which correspond to the core edges, partially pressed into billet wall.
На фиг. 1 изображена труба по предлагаемому способу; на фиг. 2 - то же, поперечное сечение.FIG. 1 shows a pipe according to the proposed method; in fig. 2 is the same cross section.
Теплообменна труба содержит наружное оребрение 1 и размещенный внутри нее сердечник 2 с ребрами 3.The heat exchange tube contains the outer fins 1 and the core 2 placed inside it with ribs 3.
Внутри цилиндрической заготовки трубы размещают сердечник 2 с ребрами 3. Затем наружную поверхность заготовки обжимают с образованием оребрени 1 и придают заготовке форму многоугольника в .поперечном йеченни, вершины которого соответствуют ребрами 3 сердечника 2.Inside the cylindrical billet of the pipe, a core 2 with ribs 3 is placed. Then the outer surface of the billet is crimped to form ribbing 1 and give the billet a polygon shape in a transverse junction whose peaks correspond to the ribs 3 of core 2.
Усили , прикпадьгоаемые при этом, позвол ют частично вдавить ребра сердечника в стенку заготовки.The forces clamped in this way partially allow the core ribs to be pressed into the wall of the workpiece.
Предлагаемый способ изготовлени теплообменной трубы позвол ет упростить процесс ее наружного оребрени с одновременным закреплением внутри нее сердечника.The proposed method for the manufacture of a heat exchange tube makes it possible to simplify the process of its external finning while fastening the core inside it.
