Description
Die Erfindung bezieht sich auf ein Wärmetauscherrohr mit Längsrippen, bei dem ein Wärmetausch zwischen einem im Rohrinneren Wärme abgebenden Stoff und einem an der Rohraußenseite parallel zur Rohrachse strömenden Medium stattfindet und sich die Metallmenge pro Längeneinheit der Rippe von einem Rohrende zum anderen fortschreitend ändert. Es ist bereits bekannt, die Rohre für Wärmetauscher, in welchen zwei fließende Medien ihre Wärme austauschen, indem das eine im Inneren der Rohre und das andere am Äußeren der Rohre vorbeiströmt, mit solchen Längsrippen zu versehen, daß sich die Metallmengen pro Längeneinheit der Rippe von einem Rohrende zum anderen ändert, um den Temperaturänderungen der beteiligten Mittel Rechnung zu tragen. Beispielsweise läßt sich die Rippenoberfläche vom Eingang zum Ausgang des Rohres hin in der Weise ändern, daß die Rippen in denjenigen Bereichen größer sind, die am Ausgang liegen und in welchen der Temperaturunterschied geringer ist.The invention relates to a heat exchanger tube with longitudinal ribs, in which a heat exchange between a substance emitting heat inside the pipe and one on the outside of the pipe parallel to the pipe axis flowing medium takes place and the amount of metal per unit length of the rib of one Pipe end to the other progressively changes. It is already known that the tubes for heat exchangers in which two flowing media exchange their heat, one inside the tube and the other others flow past the outside of the pipes to provide longitudinal ribs such that the amounts of metal per unit length of the rib from one pipe end to the other changes to reflect the temperature changes to take account of the funds involved. For example, the rib surface can be removed from the entrance change towards the exit of the tube in such a way that the ribs are larger in those areas which are located at the exit and in which the temperature difference is lower.
Es ist auch bereits bekannt, Wellungen, auch unsymmetrische Wellungen, auf den diametral angeordneten Längsrippen von Wärmetauscherrohren vorzusehen. Demgegenüber ist es Zweck der Erfindung, ein Wärmetauscher- oder Wärmeabsorberrohr mit veränderlicher Intensität der Wärmeaustauschoberfläche zu schaffen, bei dem die Längsrippen sich pro Längeneinheit ändernde Metallmenge aufweist und die Längsrippen gewellt sind. Nach der Erfindung sind hierzu die Rippen durch an sich bekannte gewellte Metallbänder gebildet, wobei die Wellungen sich in Anzahl und Tiefe fortschreitend von einem Rohrende zum anderen ändern.It is also already known that corrugations, including asymmetrical corrugations, on the diametrically arranged Provide longitudinal ribs of heat exchanger tubes. In contrast, it is the purpose of the invention, a Heat exchanger or heat absorber tube with variable intensity of the heat exchange surface to create, in which the longitudinal ribs have a changing amount of metal per unit length and the longitudinal ribs are wavy. According to the invention, for this purpose the ribs are formed by corrugated metal strips known per se formed, the corrugations progressing in number and depth from one pipe end to the change another.
Vorzugsweise sind dabei die Rippen nur am äußeren Rand gewellt.The ribs are preferably only corrugated on the outer edge.
In einer abgewandelten Ausführung der Erfindung sind die Rippen durch an sich bekannte, sinusförmig gebogene und senkrecht zur Rohroberfläche angebrachte Metalldrähte gebildet, wobei die mehr oder weniger dichten Wellungen sich fortschreitend von einem Rohrende zum anderen ändern.In a modified embodiment of the invention, the ribs are sinusoidal, which are known per se bent and perpendicular to the pipe surface attached metal wires formed, the more or less dense corrugations progressively change from one pipe end to the other.
Die Erfindung bezieht sich nicht allein auf Wärmetauscher, sondern auch auf Wärmeabsorber, bei welchen das fließende Medium das Äußere eines Rohres umströmt, während das Rohrinnere einen festen Körper enthält, der bei gleichbleibender oder sich ändernder Temperatur Wärme abgibt.The invention relates not only to heat exchangers, but also to heat absorbers in which the flowing medium flows around the outside of a pipe, while the inside of the pipe flows around a solid body which gives off heat at constant or changing temperature.
Einige Ausführungsbeispiele der Erfindung werden unter Bezugnahme auf die Zeichnung genauer erläutert: Some embodiments of the invention are explained in more detail with reference to the drawing:
Fig. 1 und 2 zeigen zwei zur Herstellung von erfindungsgemäßen Wärmetauscherrohren geeignete Ausführungsformen von aus Metalldraht bestehenden Rippen;1 and 2 show two embodiments suitable for producing heat exchanger tubes according to the invention of ribs made of metal wire;

Fig. 4 zeigt das in Fig. 3 dargestellte Rohr, in Achsrichtung gesehen;FIG. 4 shows the tube shown in FIG. 3, seen in the axial direction;
Fig. 5 stellt in perspektivischer Darstellung eine abgeänderte Ausführungsform eines Rohres mit querliegenden Rippen dar; Fig. 5 is a perspective view of a modified embodiment of a tube with transverse ribs;
Fig. 6 ist eine perspektivische Ansicht eines zu einer Längsrippe geformten Blechbandes;6 is a perspective view of a sheet metal strip formed into a longitudinal rib;
Fig. 7 veranschaulicht ein Rohr mit zwei gemäß Fig. 6 ausgebildeten Längsrippen.FIG. 7 illustrates a tube with two longitudinal ribs designed according to FIG. 6.
Bei der Herstellung von Rippen für ein erfindungsgemäßes Rohr mit veränderlicher Wärmetauschfläche kann von einem nach einer zylindrischen Schraubenlinie, z. B. über einen zylindrischen Dorn, zu einer Wendel gewickelten Metalldraht b ausgegangen werden, dessen Windungen nach dem Wickeln in Längsrichtung der Wendel derart auseinandergezogen werden, daß sich, wie Fig. 1 erkennen läßt, zwischen den aufeinanderfolgenden Windungen a von A nach B zunehmende Abstände ergeben. DieWindungen a können anschließend in eine Ebene flachgedrückt werden. Diese Ausführung ist ähnlich den militärischen Drahthindernissen, die durch Auseinanderziehen eines ringförmigen Stacheldrahtbundes entstehen.In the manufacture of fins for a tube according to the invention with a variable heat exchange surface, from one after a cylindrical helical line, for. B. be assumed b over a cylindrical mandrel, wound into a helical metal wire, the turns are pulled apart after winding in the longitudinal direction of the helix such that can recognize as shown in Fig. 1, between the successive windings of a of A to B increasing distances result. The turns a can then be flattened into a plane. This design is similar to the military wire obstacles that are created by pulling apart a ring-shaped barbed wire bundle.
Nach einer anderen, in Fig. 2 dargestellten Herstellungsweise kann der Metalldraht c einfach nach einer sinoidalen Linie gewellt werden, wobei die Abstände zwischen den Wellen von A nach B hin fortschreitend größer werden.According to another manufacturing method shown in FIG. 2, the metal wire c can simply be corrugated according to a sinusoidal line, the distances between the corrugations becoming progressively larger from A to B.
