Description

Die vorliegende Erfindung betrifft einen Niederdruckwärmeaustauscher, dessen für die Wärmeübertragung wirksame Teile aus geraden, mit Rippen versehenen, miteinander verbundenen extrudierten Rohrabschnitten bestehen. The present invention relates to a low-pressure heat exchanger, the parts effective for heat transfer consisting of straight, finned, interconnected extruded pipe sections.

Wäremaustauscher, die aus einzelnen mit Rippen versehenen Rohrabschnitten zusammengebaut sind, weisen üblicherweise eine tragende Konstruktion auf, an denen die wirksamen Teile montiert sind. Je nach Art der Anordnung der durchströmten Rohrabschnitte kann die tragende Konstruktion ein Stahlrahmen sein, wie in der US-PS 3 672 446, oder eine tragende Mittelsäule, wie in der DE-OS 3 040 802 beschrieben. Heat exchangers, which are assembled from individual pipe sections provided with fins, usually have a load-bearing construction on which the effective parts are mounted. Depending on the type of arrangement of the flowed through pipe sections, the supporting structure can be a steel frame, as in US Pat. No. 3,672,446, or a supporting center column, as described in DE-OS 3,040,802.

Dank den tragenden Konstruktionen waren die Kühlrippen der nebeneinander verlaufenden Rohrabschnitte berührungsfrei voneinander distanziert. Die üblichen Wärmeaustauscher für cryogene Anwendungszwecke sind für Niederdruck aus einer Aluminiumlegierung extrudiert, wobei das Rohr mit den sternförmig angeordneten Kühlrippen einstückig gefertigt wird. Thanks to the load-bearing constructions, the cooling fins of the pipe sections running side by side were spaced apart from one another without contact. The usual heat exchangers for cryogenic applications are extruded for low pressure from an aluminum alloy, with the tube being made in one piece with the star-shaped cooling fins.

Die meisten Wärmeaustauscher wurden fertig montiert und verpackt und so zu dem oftmals abgelegenen Verwendungsort transportiert. Most of the heat exchangers were assembled and packaged and transported to the often remote location.

Die Transportkosten waren dabei aus zwei Gründen hoch; einerseits war das Volumen der zusammengebauten Einheit gross, zum anderen benötigte man sowohl während des Transportes als auch beim Aufbau am Standort die Hilfe von Kranen. Dass zusätzlich noch der Rahmen bzw. die Tragsäule als Einheit hinzu kam, verteuerte auch noch die Herstellung. The transportation costs were high for two reasons; on the one hand, the volume of the assembled unit was large, and on the other hand, the help of cranes was required both during transport and when setting up the site. The fact that the frame or the support column was added as a unit also made the production more expensive.

Die vorliegende Erfindung stellt sich daher die Aufgabe, einen Wärmeaustauscher gemäss Oberbegriff des Patentanspruches zu schaffen, der ohne tragende Konstruktion auskommt und einfach ohne Hilfe eines Kranes von einem Arbeiter montiert werden kann. The present invention therefore has as its object to provide a heat exchanger according to the preamble of the claim, which does not require a supporting structure and can be easily assembled by a worker without the help of a crane.

Diese Aufgabe löst ein Wärmeaustauscher, dessen für die Wärmeübertragung wirksame Teile aus geraden, mit Rippen versehenen, miteinander verbundenen, extrudierten Rohrabschnitten zusammengebaut ist, dadurch, dass die benachbarten extrudierten Rohrabschnitte mit ihren Rippen anein-anderliegen, wobei die sich berührenden Rippen peripher angeordnete Formschlussmittel aufweisen, und dass die einander berührenden Rohrabschnitte mittels Kraftschluss relativ zueinander fixiert sind. This task is solved by a heat exchanger, the parts of which are effective for heat transfer and which are assembled from straight, finned, interconnected, extruded tube sections, in that the adjacent extruded tube sections lie against one another with their fins, the fins that come into contact with one another having peripherally arranged form-locking means , and that the mutually contacting pipe sections are fixed relative to one another by means of frictional connection.

In der Zeichnung ist ein bevorzugtes Ausführungsbeispiel des Erfindungsgegenstandes im Detail und gesamthaft in ver: schiedenen Ansichten dargestellt und anhand der nachfolgenden Beschreibung erläutert. Es zeigt: In the drawing, a preferred exemplary embodiment of the subject matter of the invention is shown in detail and in its entirety in various views and explained with the aid of the following description. It shows:

Figur 1 einen Querschnitt durch ein extrudiertes Rohr mit zwei gebogenen Rippen. 1 shows a cross section through an extruded tube with two curved ribs.

Figur 2 eine perspektive Ansicht eines Wärmeaustauschers gefertigt aus dem extrudierten Rohr nach Figur 1 und Figure 2 is a perspective view of a heat exchanger made from the extruded tube of Figure 1 and

Figur 3 eine Aufsicht auf den Wärmeaustauscher nach Figur 2. Figure 3 is a plan view of the heat exchanger according to Figure 2.

Figur 4 zeigt die kraftschlüssige Verbindung zweier extru-dierter Rohrabschnitte im Detail und Figure 4 shows the positive connection of two extruded pipe sections in detail and

Figur 5 eine schematische Darstellung einer Verdampferbatterie für den intermittierenden Betrieb. Figure 5 is a schematic representation of an evaporator battery for intermittent operation.

Das eigentliche extrudierte Rohr ist mit 1 bezeichnet. Von ihm aus verlaufen einige Rippen etwa radial nach aussen. Besonders markant sind zwei einander diametral gegenüberliegende gebogene Rippen 2. An den Rippen 2 sind endständig Formschlussmittel 3 angeformt. Hierbei kommen grundsätzlich alle Feder/Nut-Formen in Frage. Die beiden gebogenen Rippen 2 bilden zusammen einen Viertelkreis. The actual extruded tube is labeled 1. From it some ribs run approximately radially outwards. Particularly distinctive are two diametrically opposed curved ribs 2. Form-fitting means 3 are integrally formed on the ribs 2. In principle, all tongue and groove shapes come into question. The two curved ribs 2 together form a quarter circle.

Auf der konvexen Seite einer der beiden gebogenen Rippen 2 sind zwei kurze, gegeneinander gerichtete, im Querschnitt hakenförmige Rippen 4 angeformt, die zusammen ein einseitig offenes kastenförmiges Profil bilden. On the convex side of one of the two curved ribs 2, two short, mutually directed, hook-shaped ribs 4 are formed, which together form a box-shaped profile open on one side.

An der konvexen Seite zwischen den beiden gebogenen Rippen 2 sind zwei weitere radial nach aussen gerichtete Rippen 5. Im rohrnahen Bereich schliessen die Rippen 5 einen Winkel von 90° ein. In einem gewissen Abstand von Rohr 1 sind die Rippen 5 so geknickt, dass ihre Enden 6 parallel verlaufen. On the convex side between the two curved ribs 2 there are two further radially outwardly directed ribs 5. In the region near the tube, the ribs 5 enclose an angle of 90 °. At a certain distance from tube 1, the ribs 5 are bent so that their ends 6 run parallel.

Auch die Rippen 5 weisen endständig Formschlussmittel 7 auf, die gleich geformt sind wie die Formschlussmittel 3 an den gebogenen Rippen 2. The ribs 5 also have form-fitting means 7 at the end, which are shaped in the same way as the form-fitting means 3 on the curved ribs 2.

An der konkaven Seite zwischen den beiden gebogenen Rippen 2 sind zwei radial nach innen gerichtete Rippen 8, deren Endbereiche 9 auch wieder parallel verlaufen. Dabei ist der Abstand der parallelen Endbereiche 9 der Rippen 5 so gross, dass die parallelen Endbereiche 9 der Rippen 8 dazwischen Platz haben, wenn die extrudierten Profilabschnitte für den Transport gestapelt sind. Die Enden oder Rippenbereiche 9 sind nochmals um 90° zueinander verlaufend On the concave side between the two curved ribs 2 are two radially inwardly directed ribs 8, the end regions 9 of which also run parallel again. The distance between the parallel end regions 9 of the ribs 5 is so great that the parallel end regions 9 of the ribs 8 have space in between when the extruded profile sections are stacked for transport. The ends or rib areas 9 are again 90 ° to each other

geknickt, so dass im gestapelten Zustand die Enden 10 auf den Rippen aufliegen. Zwischen den beiden Rippen 8 auf der konkaven Seite ist eine weitere Rippe II angeformt, die endständig eine gewölbte Anschlagfläche 12 aufweist. kinked so that the ends 10 rest on the ribs when stacked. Between the two ribs 8 on the concave side, a further rib II is formed, which has a curved stop surface 12 at the end.

Diese liegt wiederum im gestapelten Zustand auf dem Rohr 1 zwischen den beiden Rippen 5 auf. This is in turn stacked on the tube 1 between the two fins 5.

Als Formschlussmittel 3,7 kommen grundsätzlich alle Arten von Feder/Nut-Konstruktionen in Frage. Bei der Länge der einzelnen Rohrabschnitte sind Konstruktionen, die einfach anliegend ineinanderpassen, zu bevorzugen gegenüber solchen, die ineinandergeschoben werden müssen. In principle, all types of tongue and groove constructions come into question as form-locking means 3.7. In terms of the length of the individual pipe sections, constructions that fit snugly into one another are preferred over those that have to be pushed into one another.

In der Figur 2 ist ein Wärmeaustauscher aus vier extrudierten Rohrabschnitten, wie in der Figur 1 dargestellt, zusammengestellt. Die vier extrudierten Rohrabschnitte sind alle mit den konkaven Seiten zueinander gerichtet angeordnet und bilden so einen Zylinder. FIG. 2 shows a heat exchanger composed of four extruded pipe sections, as shown in FIG. 1. The four extruded pipe sections are all arranged with the concave sides facing each other and thus form a cylinder.

Die einzelnen geraden extrudierten Rohrabschnitte 1 sind über entsprechend gebogene Rohrstücke 13,14 miteinander verbunden : Dabei ist der Verlauf des Mediums so gewählt, dass der Einlass 15 und der Auslass 16 einander diametral gegenüberliegen. The individual straight extruded pipe sections 1 are connected to one another via correspondingly bent pipe sections 13, 14: the course of the medium is chosen such that the inlet 15 and the outlet 16 are diametrically opposite one another.

In das einseitig offene kastenförmige Profil 4 sind die Füsse 17, die aus einem Flachstab geformt sind, eingeschoben und mit einer Druckplatte 18 festgeschraubt. Die einzelnen extrudierten geraden Rohrabschnitte 1 sind im Bereich der Formschlussmittel 3 mittels Klammern 20 in Figur 4 zusammengehalten. The feet 17, which are formed from a flat bar, are pushed into the box-shaped profile 4, which is open on one side, and screwed tight with a pressure plate 18. The individual extruded straight pipe sections 1 are held together in the area of the form-fitting means 3 by means of clips 20 in FIG. 4.

Für cryogene Zwecke werden die hier gezeigten Wärme-5 austauscher im wesentlichen als Verdampfer eingesetzt. Eine Einheit wie in Figur 2 dargestellt kann bei einer Bauhöhe von ca. 5 m eine Leistung von 100 NmVh erbringen. Dabei wird das vorerst flüssige Gas von ca. —200°C in extra 10°C unterhalb der herrschenden Aussentemperatur erwärmtes Gas io umgewandelt. For cryogenic purposes, the heat exchangers shown here are essentially used as evaporators. A unit as shown in Figure 2 can achieve an output of 100 NmVh at a height of about 5 m. The initially liquid gas is converted from approx. -200 ° C to gas heated to 10 ° C below the prevailing outside temperature.

Die Figur 3 zeigt eine Verdampfereinheit 30 von oben. Für Grossanlagen wird eine Vielzahl zu ganzen Verdampferanlagen - wie in Figur 5 dargestellt - vereint. Dabei erfolgt die Verbindung der Verdampfereinheiten 30 über die parallelen 15 Rippen 5, 6, 7. Die kraftschlüssige Verbindung kann wiederum mittels der Klammern 20 geschehen. FIG. 3 shows an evaporator unit 30 from above. For large systems, a large number are combined to form entire evaporator systems, as shown in FIG. 5. The connection of the evaporator units 30 takes place via the parallel 15 ribs 5, 6, 7. The non-positive connection can again be made by means of the clamps 20.

Neben der bevorzugten Ausführungsform wie beschrieben lassen sich zahllose andere Formen der extrudierten Rohre herstellen. Die Grundidee aber bleibt dieselbe, nämlich die 20 Verbindung der mit Kühlrippen versehenen extrudierten geraden Rohre über die Kühlrippen zu Wärmeaustauschereinheiten, die keine spezielle tragende Konstruktion mehr erfordert, somit raumsparend transportiert und an Ort und Stelle einfach zusammengesetzt werden kann. In addition to the preferred embodiment as described, countless other shapes of extruded tubes can be made. However, the basic idea remains the same, namely the connection of the extruded straight tubes provided with cooling fins via the cooling fins to heat exchanger units, which no longer requires a special supporting structure, so that they can be transported in a space-saving manner and easily assembled on site.
