Abstract

The heat exchanger tube consists of a tubular core (2), of steel or similar material, with cast iron fins or ribs (4), cast in situ around the tubular core. A heat exchanger can be constructed by welding a number of such tubes to header tanks. These fins or ribs (4) increase the rate of heat transfer and may be of different forms and arranged in different positions with respect to the tubular core (2). The tubular core (2) may have a circular cross-section or any other suitable cross-section. USE - Heat exchanger with composite tubes.

Description

Die Erfindung betrifft ein Wärmetauscherrohr, das wesentlich dadurch gekennzeichnet ist, daß es einen röhrenförmigen Kern aus Stahl o. dgl. aufweist, auf welchem eine Deckung aus Gußeisen oder ähnlichem Material angegossen ist, wobei diese Deckung mit Bestandteilen zur Erhöhung des Wärmetauschs, wie Rippen, Stege, Sprossen u.ä. versehen ist.The invention relates to a heat exchanger tube, which is essential is characterized in that it is made of a tubular core Steel or the like., On which a cover made of cast iron or similar material is cast on, this covering with Components for increasing the heat exchange, such as ribs, webs, Sprouts and the like is provided.

Die Erfindung betrifft ferner einen Wärmetauscher, der dadurch gekennzeichnet ist, daß sie durch die Anordnung einer Reihe von erfindungsgemäßen Rohren, die miteinander durch Schweißen und/oder mechanische Teile verbunden sind, hergestellt ist.The invention further relates to a heat exchanger which thereby is characterized by the arrangement of a series of tubes according to the invention, which are welded together and / or mechanical parts are connected.

Das erfindungsgemäße Wärmetauscherrohr und ein mit einer Vielzahl solcher Rohre hergestellter Wärmetauscher werden beispielsweise jedoch nicht beschränkungsweise anhand der folgenden Figuren der einzigen beiliegenden Zeichnung näher erläutert.The heat exchanger tube according to the invention and one with a variety Such heat exchangers are manufactured, for example but not by way of limitation with reference to the following figures in FIG single enclosed drawing explained in more detail.

Die Figuren von 1 bis 5 zeigen Wärmetauscherrohre mit unter­ schiedlich ausgebildeten Deckungen, und Fig. 6 stellt einen mit den in Fig. 1 bis 5 gezeigten Wärmetauscherrohren gebildeten Kessel, insbesondere für die Hausheizung, dar.The figures from 1 to 5 show heat exchanger tubes with under differently designed coverings, and Fig. 6 shows a boiler formed with the heat exchanger tubes shown in Figs. 1 to 5, in particular for domestic heating.

Wie aus den Fig. 1 bis 5 zu ersehen ist, weist das Wärme­ tauscherrohr 1 einen röhrenförmigen Kern 2 aus Metall oder ähnlichem Material auf, auf welchem eine Deckung bzw. Umhüllung 3 aus Gußeisen angegossen ist, die unterschiedlich ausgebildete und gerichtete Mittel 4, wie zum Beispiel Rippen besitzt, die zur Erhöhung des Wärmetauschs bestimmt sind.As can be seen from FIGS . 1 to 5, the heat exchanger tube 1 has a tubular core 2 made of metal or similar material, on which a cover or casing 3 is cast from cast iron, the differently designed and directed means 4 , such as for example, has fins designed to increase heat exchange.

Mit Bezug auf Fig. 6 ist der Kessel 5 aus einer Vielzahl Wärmetauscherrohre 1 zusammengesetzt, die paketweise eingebaut und miteinander durch Schweißen und/oder mechanische Teile verbunden sind. In dieser Fig. 6 sind mit 6 die zwei oberen Sammelrohre, mit 7 die Brennkammer, mit 8 die Tür, an welcher ein Brenner 9 angebaut ist, und mit 10 der Rauchzug in Richtung zum Auslaß 11 angegeben, wobei dieser Rauchzug gegenströmig zum Wasserweg 12 mit Einlauf A und Auslauf B vorgesehen ist.With reference to Fig. 6, the boiler 5 is composed of a plurality of heat exchanger tubes 1 , which are installed in packages and are connected to one another by welding and / or mechanical parts. In this FIG. 6, the two upper headers, with 7, the combustor 8, the door to which a burner 9 with 6 grown, and indicated with 10 of the flue in the direction of the outlet 11, and this smoke path countercurrent to the waterway 12 with inlet A and outlet B is provided.

Die Mittel 4 können natürlich so ausgebildet sein, daß der Wärmetausch in einer fortschreitenden Weise entlang des Verlaufs des Wärmetauschers 5 erfolgt.The means 4 can of course be designed so that the heat exchange takes place in a progressive manner along the course of the heat exchanger 5 .

In diesem Zusammenhang bezeichnet der Begriff "Wärmetauscher" jegliches Gerät, das zur Wärmeübertragung von einem Körper zum anderen, meistens von einem Fluid zum anderen hergestellt und benutzt wird.In this context, the term "heat exchanger" denotes any device that is used to transfer heat from one body to another other, mostly made from one fluid to another and is used.
