Die Erfindung bezieht sich auf ein Innenrippenrohr für Heizkessel für Niedertemperaturheizungen, bestehend aus einteiligen, in Längsrichtung berippten und an den Längsseiten miteinander verschweißten Mantelstreifen mit einer dem Innenrippenrohr entsprechenden Länge. The invention relates to an inner finned tube for heating boilers for low-temperature heating, consisting of one-piece, ribbed lengthways and jacket strips welded to one another on the long sides with an inner fin tube corresponding length.
Die Verwendung derartiger Innenrippenrohre für Niedertemperaturheizungen verhindert wegen des besseren Wärmeübergangs das Auftreten von Kondenswasser im berippten Bereich. Bei den bisherigen Systemen werden dabei entweder Mantelstreifen aus Druckguß oder Strangpreßprofile verwendet. Beide Profilarten sind jedoch außerordentlich teuer, wobei bei den Strangpreßprofilen noch eine sehr aufwendige Montage hinzukommt. Nach den bisherigen Fertigungsverfahren lassen sich nämlich derartige berippte Strangpreßprofile nur in der Weise herstellen, daß die Rippen auf der konvexen Seite angeordnet sind, während man sie ja zur Bildung des Innenrippenrohrs auf der konkaven Seite benötigt. Dies macht ein Umpressen der Strangpreßprofile erforderlich. Hinzu kommt, daß beim Strangpressen die Matrizen sehr stark abgenutzt werden, so daß sich fortlaufend die Abmessungen der Profile ändern. Dies wiederum macht es erforderlich, daß zum Aufbau eines Innenrippenrohrs die Strangpreßprofile ausgesucht werden müssen, um die vorhandenen Fertigungstoleranzen auszugleichen. The use of such inner finned tubes for low temperature heating prevents condensation from occurring in the ribbed area. In the previous systems either jacket strips are used used from die-cast or extruded profiles. However, both types of profile are extraordinary expensive, with the extruded profiles also requiring a very complex assembly. According to the previous manufacturing processes, such ribbed extruded profiles can namely manufacture only in such a way that the ribs are arranged on the convex side, while they are needed to form the inner fin tube on the concave side. This makes pressing around the extruded profiles necessary. In addition, the Extrusion the dies are worn very heavily, so that they are continuously change the dimensions of the profiles. This in turn makes it necessary that for Structure of an inner finned tube the extruded profiles must be selected in order to to compensate for the existing manufacturing tolerances.
Dieses Aussuchen kann zwar gemäß einem in der deutschen Offenlegungsschrift 29 20 057 gemachten Vorschlag vermieden werden, wenn die Seitenränder der Mantelstreifen abwechselnd von der einen bzw.This selection can be made in accordance with one of the German Offenlegungsschrift 29 20 057 can be avoided if the side edges of the jacket strips alternately from one or the other
anderen Seite einspringend nur verjüngt ausgebildet sind, so daß eine Überlappung stattfinden kann, die einen solchen Toleranzausgleich ermöglicht. In jedem Fall benötigt man aber auch dort wiederum teuere Strangpreßprofile, die zusätzlich nach der Fertigung umgepreßt werden müssen, damit die Rippen auf der konkaven Seite liegen.other side are only tapered, so that one Overlapping can take place, which enables such tolerance compensation. In In any case, however, you also need expensive extruded profiles there, in addition must be re-pressed after production, so that the ribs on the concave side lie.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Innenrippenrohr zu schaffen, welches aus einfacher herzustellenden und einfacher zu montierenden Mantelstreifen gebildet ist. The invention is therefore based on the object of an inner finned tube to create, which from easier to manufacture and easier to assemble Coat strip is formed.
Zur Lösung dieser Aufgabe ist bei einem Innenrippenrohr der eingangs genannten Art gemäß der Erfindung vorgesehen, daß die Mantelstreifen T- oder U-förmige Walz- bzw. Abkantprofile sind, wobei der Querschenkel des T- und der Basisschenkel des U-Profils den Rohrmantel bilden. To solve this problem, in the case of an inner finned tube, the mentioned type provided according to the invention that the jacket strips T-shaped or U-shaped Rolled or folded profiles are, where the Transverse legs of the T and the base leg of the U-profile form the pipe jacket.
Durch die erfindungsgemäße Vermeidung der Verwendung von Mantelstreifen, an denen bereits mehrere Rippen angeformt sind, die jedoch dann in wesentlich umständlicher Weise durch Strangpressen und Umformen erzeugt werden müssen, lassen sich handelsübliche preiswerte gewalzte T-Profile sowie sehr einfach durch Abkanten von Blechen herstellbare U-Profile verwenden, so daß die Herstellung eines Innenrippenrohrs wesentliche einfacher und billiger wird. Das Vorhandensein von mehr Schweißnähten gegenüber breiteren stranggepreßten Mantelstreifen mit mehreren Rippen verkompliziert die Herstellung praktisch nicht, da das Verschweißen der erfindungsgemäßen Profile sehr einfach in Schweißautomaten erfolgen kann, wie sie bereits zum Schweißen von Längsnähten an Heizregistern im Handel sind. Unter Verwendung solcher gleichartiger Bauteile lassen sich dabei sehr einfach beliebige Rohrdurchmesser im 20 mm-Raster herstellen. By avoiding the use of coat strips according to the invention, on which several ribs are already formed, which, however, are much more cumbersome Way must be produced by extrusion and forming, can be commercially available inexpensive rolled T-profiles as well as very easy to produce by bending sheet metal Use U-profiles, so that the production of an inner finned tube is much easier and gets cheaper. The presence of more welds versus wider ones Extruded jacket strips with multiple ribs complicate manufacture practically not, since the welding of the profiles according to the invention is very simple can be done in automatic welding machines, as they are already used for welding longitudinal seams on heating registers are available in stores. Using such components of the same type any pipe diameter in a 20 mm grid can be produced very easily.
Prinzipiell ließe sich ein Innenrippenrohr lediglich unter Verwendung von T-Profilen herstellen, doch würde dies es erforderlich machen, daß Profile verwendet werden, deren Querschenkel im Verhältnis zum Längssteg relativ schmal ist. Um handelsübliche gewalzte T-Profile einsetzen zu können, soll in Ausgestaltung der Erfindung abwechselnd ein T- und ein U-Profil nebeneinander angeordnet sein. Um ein gleichmäßiges Konvergieren der nach innen ragenden Schenkel der Profile zu erzielen, sollen die Schenkel der U-Profile dabei zum freien Ende hin aufeinander zugeneigt sein. Dies ist bei der erfindungsgemäßen Fertigung der U-Profile als Abkantprofile völlig problemlos und erfordert keinen besonderen Fertigungsaufwand. Bei den erfindungsgemäßen Profilen hat man nur geringe Maßtoleranzen, so daß sich ein einheitlicher Luftspalt beim Schweißen und damit eine gute Durchschweißung ergibt. Die einfache und billige Herstellbarkeit der erfindungsgemäßen Innenrippenrohre ermöglicht eine Ganzberippung der Brennkammern, so daß an keiner Stelle eine Kondenswasserbildung möglich ist. Infolge der teueren und umständlichen Herstellung der bisher verwendeten Innenrippenrohre hat man nämlich auf die Ganzberippung in den meisten Fällen verzichten müssen. In principle, an inner finned tube could only be used of T-profiles, but this would require that profiles be used whose transverse legs are relatively narrow in relation to the longitudinal web. To commercial To be able to use rolled T-profiles should alternate in an embodiment of the invention a T- and a U-profile can be arranged next to one another. To converge evenly to achieve the inwardly protruding legs of the profiles, the legs of the U-profiles should be inclined towards one another towards the free end. This is with the Production of the U-profiles according to the invention as folding profiles completely problem-free and does not require any special manufacturing effort. With the profiles according to the invention you have only small dimensional tolerances, so that there is a uniform air gap when Welding and thus a good penetration result. The simple and cheap manufacturability the inner finned tubes according to the invention enables full ribbing of the combustion chambers, so that condensation is not possible at any point. As a result of the expensive and laborious production of the inner finned tubes used so far is namely have to do without full ribbing in most cases.
Die Erfindung wird nachfolgend anhand der Beschreibung eines Ausführungsbeispiels sowie der Zeichnung, die einen Schnitt durch ein abwechselnd aus T- und U-Profilen zusammengesetztes Innenrippenrohr zeigt, erläutert. The invention is explained below with reference to the description of an exemplary embodiment as well as the drawing, which shows a section through an alternating T and U profiles shows assembled inner finned tube explains.
