Abstract
Description
Die vorliegende Erfindung betrifft einen Wärmetauscher, bestehend aus einem Rohr, dessen äußere Oberfläche zumindest teilweise mit Kühlrippen versehen ist. Darüber hinaus betrifft die Erfindung ein Verfahren zur Herstellung eines Wärmetauschers bestehend aus einem Rohr, dessen Oberfläche zumindest teilweise mit Kühlrippen besetzt ist, deren vom Rohr wegweisenden freien Kanten mit wenigstens einer Abdeckung versehen sind.The present invention relates to a heat exchanger consisting of a Pipe whose outer surface is at least partially provided with cooling fins. Furthermore, the invention relates to a method for producing a Heat exchanger consisting of a tube, the surface of which at least is partly covered with cooling fins, the free edges of which point away from the pipe are provided with at least one cover.
Wärmetauscher der beschriebenen Art sind bekannt und umfangreich im Einsatz. Insbesondere werden entsprechende Wärmetauscher beispielsweise in Kraftwerken eingesetzt. Besonders werden solche Wärmetauscher als luftgekühlte Kondensatoren in Kraftwerken, oder als Industriekühler in der Chemie und der Lebensmittelindustrie eingesetzt. Sie führen in verschiedenen Prozessen die benötigte Energie ab oder zu. Hier werden abgeflachte Stahlrohre, deren äußere Oberfläche mit Aluminium beschichtet ist für das zu kühlende Medium verwendet. Auf den äußeren Oberflächen der mit Alu beschichteten Stahlrohre sind Kühlrippen angeordnet, die ihrerseits mit einem Kühlmedium überströmt werden, beispielsweise Kühlluft, Kühlgas oder dergleichen. Es ist bekannt, diese Rippen dadurch zu bilden, daß entsprechende Bleche durch mehrfache im wesentlichen rechtwinklige Abfaltungen ziehharmonikaartig gefaltet werden. Die gebildeten Rippenbleche werden dann auf der Oberfläche des Rohres angeordnet und mit dieser fest verbunden. Heat exchangers of the type described are known and are in extensive use. In particular, corresponding heat exchangers are used, for example, in Power plants used. Such heat exchangers are considered to be air-cooled Capacitors in power plants, or as industrial coolers in chemistry and Used in the food industry. They carry out the in different processes required energy from or to. Here are flattened steel pipes, the outer Surface coated with aluminum is used for the medium to be cooled. There are cooling fins on the outer surfaces of the steel tubes coated with aluminum arranged, which in turn are flooded with a cooling medium, for example cooling air, cooling gas or the like. It is known these ribs to form in that corresponding sheets by multiple essentially right-angled folds are folded like an accordion. The educated Ribbed sheets are then placed on the surface of the tube and with this firmly connected.
Infolge des Über- oder Unterdrucks im Rohr und wegen der thermischen Spannungen neigen die abgeflachten Rohre dazu, sich aufzuwölben und damit den mechanischen Verbund zwischen Rippen und Rohroberfläche zu beeinträchtigen. Aus diesem Grunde müssen die Rippen aus entsprechend starken Blechen gebildet sein.As a result of the overpressure or underpressure in the pipe and because of the thermal The flattened pipes tend to bulge, and thus to tension the mechanical bond between the ribs and the pipe surface affect. For this reason, the ribs must be made accordingly strong sheets are formed.
Alternativ zu den beschriebenen Materialien sind auch entsprechende Wärmetauscher aus Stahl mit Stahlrippen sowie aus Kupfer und anderen gut wärmeleitenden Metallen, Keramiken und Kunststoffen bekannt.As an alternative to the materials described, there are also corresponding ones Heat exchangers made of steel with steel fins as well as made of copper and other good heat-conducting metals, ceramics and plastics known.
Es ist auch bekannt, ganze Wärmetauscherpakete aufzubauen, wobei mehrere wie beschriebene abgeflachte Rohre mit dazwischen liegenden Rippen zu einem Gesamtpaket verbunden werden. Die Rippenlagen können auch durch Zwischenbleche unterbrochen sein, die jedoch mit den jeweils angrenzenden Rippenlagen fest verbunden sind. Solche Wärmetauscherpakete verhalten sich monolitisch und es kommt sehr häufig zu Beeinträchtigungen der Verbindungen aufgrund von thermisch bedingten Ausdehnungen, Verzug und dergleichen.It is also known to build entire heat exchanger packages, with several such described flattened tubes with ribs between them into one Entire package to be connected. The rib layers can also by Intermediate sheets must be interrupted, but with the adjacent ones Rib layers are firmly connected. Such heat exchanger packages behave monolithic and very often the connections are impaired due to thermal expansion, warpage and the like.
Bei den vorbekannten Wärmetauschern sind die Herstellungsverfahren sehr aufwendig, da die die Rippen bildenden abgekanteten Bleche auf den Rohroberflächen sehr genau zur Herstellung einer guten Befestigung gehalten werden müssen, andererseits aber die freien Kanten der Rippen, die vom Rohr abstehen, sehr empfindlich sind.The manufacturing processes of the known heat exchangers are very high complex, since the bent sheets forming the ribs on the Pipe surfaces held very precisely for the production of a good fastening must, on the other hand, the free edges of the ribs from the tube stand out, are very sensitive.
Ausgehend vom vorbeschriebenen Stand der Technik liegt der Erfindung die Aufgabe zugrunde, einen Wärmetauscher der gattungsgemäßen Art dahingehend weiterzubilden, daß dieser mit geringem wirtschaftlichen Aufwand und auf einfache Weise herstellbar ist, einen verbesserten mechanischen Verbund bietet und zugleich Materialeinsparungen ermöglicht.Starting from the above-described prior art, the object of the invention is to develop a heat exchanger of the generic type in such a way that it can be produced with little economic effort and in a simple manner, offers an improved mechanical bond and at the same time enables material savings.

Dabei können die jeweils die äußeren Oberflächen bildenden Abdeckungen, die bei Paketbildungen aufeinandergelegt werden, elastisch verbunden werden, beispielsweise durch verknipsen, so daß das Gesamtpaket nicht monolitisch auf thermische Spannungen reagiert sondern diese aufnehmen kann. Dadurch wird die mechanische Dauerstandfestigkeit erheblich erhöht.The heat exchangers according to the invention can also be simple Use way to package. The outer Surface-forming covers that are stacked on top of each other when forming packages be connected elastically, for example by clipping, so that The entire package does not react monolithically to thermal tensions, but rather these can record.
