Definitions
- Brazed plate heat exchangers made of aluminum are used in numerous systems at various pressures and temperatures. They are used for example in the separation of air, the liquefaction of natural gas or in plants for the production of ethylene.

- the in FIG. 1 illustrated plate heat exchanger 1 is used to heat exchange five different process streams A, B, C, D and E.
- the heat exchanger 1 is block-shaped and equipped with a variety of means 6 for supply and discharge of the individual process media. These means 6 are referred to below and in the context of this application as a nozzle.
- the heat exchanger also has a plurality of means 7 for Distribution and collection of the individual process streams A, B, C, D and E, which are referred to below and in the context of this application as a header.
- the plate heat exchanger 1 consists of a plurality of stack-shaped arranged passages 3, which are separated by partitions 4 from each other.
- the various media flow.
- the heat exchange takes place indirectly via the heat contact, which is produced by the cover plates 5 and by the wave-shaped structure arranged in the passages (hereinafter referred to as fins in the context of this application).
- the individual media A, B, C, D and E are guided in the header 7 and distributed to the respectively provided, stacked passages 3.
- distributor fins 2 In the entrance area of the passages there are so-called distributor fins 2, which ensure an even distribution of the medium within the individual passages 3. The media thus flow transversely to the shaft direction of the fins 3 through the passages 3.
- the fins 3 are connected to the baffles 4, whereby an intensive mecanical modifier is produced. This allows a heat exchange between two different media that flow in adjacent passages 3. As seen in the flow direction at the end of the passage are similar distributor fins 2, which lead the media from the passages in the header 7, where they are collected and withdrawn through the nozzle 6. The individual passages 3 are completed by so-called sidebars 8 to the outside. The entire heat exchanger block is limited by cover plates 5 to the outside.
- Such plate heat exchangers are ideal for heat exchange of at least 2 media. By appropriate construction, however, as in FIG. 1 shown, even more than 2 media participate in the heat exchange. This allows a very effective process management and effective heat and cold utilization.

- the modules are generally cuboid and are bounded on the outer sides by cover plates,
- the modules are arranged side by side in such a way that a rectangular side of a cuboid module is immediately adjacent to a corresponding rectangular side of another cuboid module,

Hartgelötete Plattenwärmetauscher aus Aluminium werden in zahlreichen Anlagen bei verschiedensten Drücken und Temperaturen eingesetzt. Sie finden beispielsweise Anwendung bei der Zerlegung von Luft, der Verflüssigung von Erdgas oder in Anlagen zur Herstellung von Ethylen.Brazed plate heat exchangers made of aluminum are used in numerous systems at various pressures and temperatures. They are used for example in the separation of air, the liquefaction of natural gas or in plants for the production of ethylene.
Ein derartiger Plattenwärmetauscher wird beispielsweise in "The standards of the brazed aluminium plate-fin heat exchanger manufactures association" ALPEMA report (2000) beschrieben. Eine daraus entnommene Abbildung wird in der

Im Wesentlichen besteht der Plattenwärmetauscher 1 aus einer Vielzahl stapelförmig angeordneter Passagen 3, die durch Trennbleche 4 voneinander getrennt sind. In den einzelnen Passagen 3 strömen die verschiedenen Medien. Der Wärmeaustausch erfolgt indirekt über den Wärmekontakt, der durch die Deckbleche 5 und durch die in den Passagen angeordnete wellenförmige Struktur (im Folgenden und im Rahmen dieser Anmeldung als Fins bezeichnet) hergestellt wird. Über die Stutzen 6 werden die einzelnen Medien A, B, C, D und E in die Header 7 geführt und so auf die jeweils vorgesehenen, stapelförmig angeordneten Passagen 3 verteilt. Im Eingangsbereich der Passagen befinden sich sogenannte Verteilerfins 2, die für eine gleichmäßige Verteilung des Mediums innerhalb der einzelnen Passagen 3 sorgen. Die Medien strömen somit quer zur Wellenrichtung der Fins 3 durch die Passagen 3. Die Fins 3 sind mit den Trennblechen 4 verbunden, wodurch ein intensiver Wärmeleitkontakt hergestellt wird. Dadurch kann ein Wärmeaustausch zwischen zwei verschiedenen Medien erfolgen, die in benachbarten Passagen 3 strömen. In Strömungsrichtung gesehen am Ende der Passage befinden sich ähnliche Verteilerfins 2, die die Medien aus den Passagen in die Header 7 führen, wo sie gesammelt und über den Stutzen 6 abgezogen werden. Die einzelnen Passagen 3 sind durch sogenannte Sidebars 8 nach außen abgeschlossen. Der gesamte Wärmetauscherblock wird durch Deckbleche 5 nach außen begrenzt.In essence, the
Derartige Plattenwärmetauscher sind hervorragend zum Wärmeaustausch von mindestens 2 Medien geeignet. Durch geeignete Konstruktion können jedoch, wie in
Derartige Plattenwärmetauscher werden beispielsweise aus Aluminium hartgelötet. Die einzelnen Passagen mit den Fins, Verteilerfins, Deckblechen und Sidebars werden aufeinander gestapelt, mit Lot versehen und in einem Ofen hartgelötet. Auf den dadurch entstanden Block werden dann Header und Stutzen aufgeschweißt.Such plate heat exchangers are brazed, for example, aluminum. The individual passages with the fins, distributor fins, cover plates and sidebars are stacked on each other, provided with solder and brazed in an oven. On the resulting block then header and neck are welded.
Durch das eben beschriebene Herstellungsverfahren wird durch die Größe und Geometrie des Lötofens auch die maximale Größe eines derartigen Plattenwärmetauscherblockes vorgegeben. Oft erfordern jedoch die Prozesserfordernisse größere Wärmeaustauschfläche und somit größere Wärmetauscherblöcke. Um diesen Anforderungen gerecht zu werden, bestehen Plattenwärmetauscher nach dem Stand der Technik in derartigen Fällen aus mindestens zwei Modulen. Unter einem Modul wird im Rahmen dieser Anmeldung ein Wärmetauscherblock verstanden, der in einem Lötofen wie eingangs beschrieben hergestellt wird. Mehrere derartige Module werden nach dem Stand der Technik miteinander verbunden und mit gemeinsamen Headern zur Verteilung und Sammlung der am Wärmeaustausch teilnehmenden Medien ausgestattet. Die Verbindung zwischen zwei verschiedenen Modulen eines Plattenwärmetauschers erfolgt dabei nach dem Stand der Technik über Sidebars.As a result of the production method just described, the size and geometry of the soldering furnace also dictate the maximum size of such a plate heat exchanger block. Often, however, the process requirements require larger heat exchange area and thus larger heat exchanger blocks. In order to meet these requirements, plate heat exchangers according to the prior art in such cases consist of at least two modules. In the context of this application, a module is understood to be a heat exchanger block which is produced in a brazing furnace as described above. Several such modules are interconnected in the prior art and provided with common headers for distribution and collection of the heat exchanging media. The connection between two different modules of a plate heat exchanger takes place according to the prior art via sidebars.

Zwischen zwei Modulen eines derartigen Plattenwärmetauschers bildet sich somit zwischen den Deckblechen eine Luftschicht aus, die dadurch quasi eine nichtdurchströmte und nicht am Wärmeaustausch teilnehmende sowie nicht drucktragende Passage bildet. Entsprechend ist der thermische Kontakt zwischen zwei Modulen deutlich schlechter als der thermische Kontakt innerhalb eines Moduls. Dies führt zu thermischen Spannungen eines Plattenwärmetauschers mit mindestens zwei Modulen in verschiedenen Anwendungen.Between two modules of such a plate heat exchanger thus forms an air layer between the cover plates, which thereby forms quasi a non-perfused and not participating in the heat exchange and not pressure-bearing passage. Accordingly, the thermal contact between two modules is significantly worse than the thermal contact within a module. This leads to thermal stresses of a plate heat exchanger with at least two modules in different applications.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Plattenwärmetauscher mit mindestens zwei Modulen, wie vorangegangen beschrieben, derart auszugestalten, dass eine möglichst starre und feste Verbindung zwischen zwei unmittelbar benachbarten Modulen hergestellt wird. Kräfte, zum Beispiel entstehend durch thermische Spannungen zwischen zwei Modulen, sollen minimiert und die mechanische Festigkeit des gesamten, aus mindestens zwei Modulen bestehenden, Blockes soll erhöht werden.The present invention has for its object to design a plate heat exchanger with at least two modules, as described above, such that the most rigid and firm connection between two immediately adjacent modules is made. For example, forces due to thermal stress between two modules should be minimized and the mechanical strength of the entire block consisting of at least two modules should be increased.
Diese Aufgabe wird durch die Merkmale des Anspruches 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung werden in den Unteransprüchen angegeben.This object is solved by the features of
Erfindungsgemäß ist auf den beiden Deckblechen, die die jeweils unmittelbar benachbarten Seiten zweier benachbarter Module bilden (im Folgenden als Kontaktflächen bezeichnet), jeweils mindestens ein Formteil befestigt, wobei
- die Formteile derart angeordnet und ausgeformt sind, dass durch mindestens ein Formteil auf einer Kontaktfläche und ein Formteil auf der anderen Kontaktfläche die Bewegung der Module senkrecht zur Kontaktfläche verhindert wird oder
- die Formteile derart angeordnet und ausgeformt sind, dass durch mindestens ein Formteil auf einer Kontaktfläche und ein Formteil auf der anderen Kontaktfläche sowie mindestens ein zusätzliches Formteil die Bewegung der Module senkrecht zur Kontaktfläche verhindert wird.
- the mold parts are arranged and shaped such that the movement of the modules perpendicular to the contact surface is prevented by at least one molding on one contact surface and one molding on the other contact surface or
- the molded parts are arranged and shaped in such a way that the movement of the modules perpendicular to the contact surface is prevented by at least one molded part on one contact surface and one molded part on the other contact surface and at least one additional molded part.
Unter einem Formteil werden im Rahmen der Erfindung jede Art von Profilen, Stangen, Stäben, Rohren, Rohrstücken, Halbschalen, Kugeln oder ähnliches verstanden. Die Formteile können dabei aus Metall (z.B. Edelstahl oder Kupfer), Aluminium oder Plastik sein.In the context of the invention, a molding is understood to mean any type of profiles, rods, rods, tubes, pipe sections, half shells, spheres or the like. The moldings can be made of metal (eg stainless steel or copper), aluminum or plastic.
Gemäß dem Grundgedanken der Erfindung werden auf den beiden Modulen Formteile, jeweils mindestens ein Formteil pro Modul, befestigt. Die Formteile sind dabei so ausgeformt und werden derart angeordnet, dass die Bewegung senkrecht zur Kontaktfläche verhindert wird. Die Formteile verhindern also die Bewegung der beiden Module weg voneinander. Durch die Kontaktflächen werden 2 Ebenen gebildet. Entsprechend der Anordnung der Module sind diese beiden Ebenen parallel. Die Ausformung und Positionierung der Formteile erlaubt den Modulen maximal eine Bewegung in diesen Ebenen (Verschiebung, Drehung). Eine Bewegung mit einer Bewegungskomponente, die senkrecht auf diesen beiden Ebenen steht, wird durch Positionierung und Ausformung der Formteile verhindert. Die Formteile sind entsprechend so ausgeformt und positioniert, das entweder ein Formteil auf einer Kontaktfläche zusammen mit einem Formteil auf der anderen Kontaktfläche die Bewegung verhindert oder zur Verhinderung dieser Bewegung noch ein zusätzliches drittes Formteil nötig wird. Anders ausgedrückt, jede Kontaktfläche weist mindestens ein Formteil auf. Ein Formteil auf einer Kontaktfläche bildet mit einem Formteil der Kontaktfläche des Nachbarmoduls ein Paar. Je nach Ausgestaltung und Positionierung der Formteile wird die Bewegung senkrecht zur Kontaktfläche schon durch das Paar Formteile selbst oder durch das Paar Formteile in Verbindung mit mindestens einem dritten Formteil verhindert.According to the basic idea of the invention, molded parts, in each case at least one molded part per module, are fastened to the two modules. The moldings are shaped and arranged so that the movement is prevented perpendicular to the contact surface. The molded parts thus prevent the movement of the two modules away from each other. Through the contact surfaces 2 levels are formed. According to the arrangement of the modules, these two planes are parallel. The shaping and positioning of the moldings allows the modules a maximum of movement in these planes (displacement, rotation). A movement with a component of motion that is perpendicular to these two levels is prevented by positioning and shaping of the molded parts. The mold parts are correspondingly shaped and positioned so that either a molded part on a contact surface together with a molded part on the other contact surface prevents the movement or to prevent this movement, an additional third molded part is needed. In other words, each contact surface has at least one molded part. A molded part on a contact surface forms a pair with a molded part of the contact surface of the neighboring module. Depending on the design and positioning of the moldings, the movement perpendicular to the contact surface is prevented even by the pair of moldings themselves or by the pair of moldings in connection with at least one third mold part.
Durch die erfindungsgemäße Verbindung der beiden Module über die Formteile wird eine deutlich stabilere Verbindung erreicht, als nur über das Schweißen an den Seitenkanten wie im Stand der Technik beschrieben. Die Schweißverbindung an den Seitenkanten kann dabei optional zusätzlich erfolgen.The inventive connection of the two modules on the moldings a significantly more stable connection is achieved, as described only by the welding on the side edges as in the prior art. The welded connection on the side edges can optionally be made additionally.
Bevorzugt werden die Formteile auf den Kontaktflächen durch Löten, Kleben, Schweißen und/oder Heften befestigt.Preferably, the moldings are attached to the contact surfaces by soldering, gluing, welding and / or stapling.
Gemäß einer Ausgestaltung der Erfindung ist auf jeder Kontaktfläche mindestens ein U-förmiges Profilstück als Formteil mit mindestens einer Seitenkante des U-förmigen Profils auf einer Kontaktfläche befestigt, wobei die U-förmigen Profile derart angeordnet sind, das ein auf einer Kontaktfläche befestigtes U-förmiges Profil mit einem auf der anderen Kontaktfläche befestigten U-förmigen Profil ein Paar bildet, wobei die beiden Öffnungen der U-förmigen Profile eines Paares aufeinander zeigen und derart einen Hohlraum bilden, in den ein weiteres Formteil eingefügt werden kann. Bei dieser Ausgestaltung wird auf den beiden Kontaktflächen jeweils mindestens ein U-förmiges Profil befestigt. Jeweils ein U-förmiges Profil der einen Kontaktfläche bildet ein Paar mit einem U-förmigen Profil der anderen Kontaktfläche. Die U-förmigen Profile werden dabei mit einer langen Seite des U auf der Kontaktfläche befestigt. Die kurze Seite des U steht senkrecht auf der Kontaktfläche. Die beiden U-förmigen Profile eines Paares sind so orientiert, dass die offenen Seiten des U aufeinander zeigen. Zwischen den beiden Öffnungen der U-förmigen Profile eines Paares bildet sich so ein Hohlraum, in den ein weiteres zusätzliches Formteil eingefügt werden kann. Durch dieses zusätzliche Formteil wird die Bewegung der Kontaktflächen in einer Richtung senkrecht zur Kontaktfläche, d.h. entlang der kurzen Seite des U, verhindert. Die beiden an jeweils unterschiedlichen Kontaktflächen befestigten U-förmigen Profile eines Paares werden durch das zusätzliche Formteil an der Bewegung entlang der kurzen Seite des U gehindert, wodurch die Bewegung der beiden Module senkrecht zur Kontaktfläche verhindert wird.According to one embodiment of the invention, at least one U-shaped profile piece is fixed on each contact surface as a molded part with at least one side edge of the U-shaped profile on a contact surface, wherein the U-shaped profiles are arranged such that a fixed on a contact surface U-shaped Profile with a U-shaped profile attached to the other contact surface forms a pair, wherein the two openings of the U-shaped profiles of a pair show each other and thus form a cavity into which another molding can be inserted. In this embodiment, at least one U-shaped profile is attached to the two contact surfaces. In each case a U-shaped profile of a contact surface forms a pair with a U-shaped profile of the other contact surface. The U-shaped profiles are fastened with a long side of the U on the contact surface. The short side of the U is perpendicular to the contact surface. The two U-shaped profiles of a pair are oriented so that the open sides of the U face each other. Between the two openings of the U-shaped profiles of a pair so forms a cavity into which another additional molding can be inserted. By this additional molding, the movement of the contact surfaces in a direction perpendicular to the contact surface, ie along the short side of the U, prevented. The two attached to each different contact surfaces U-shaped profiles of a pair are prevented by the additional molding on the movement along the short side of the U, whereby the movement of the two modules is prevented perpendicular to the contact surface.
Vorteilhafterweise werden in dieser Ausgestaltung der Erfindung mehrere U-förmige Profile als Paare auf den Kontaktflächen angeordnet, wobei die Anordnung bevorzugt parallel und in regelmäßigen Abständen über die gesamte Kontaktfläche verteilt erfolgt. Die Länge der U-förmigen Profile entspricht zweckmäßigerweise der Länge einer Seitenkante der Kontaktfläche.Advantageously, a plurality of U-shaped profiles are arranged as pairs on the contact surfaces in this embodiment of the invention, wherein the arrangement is preferably distributed in parallel and at regular intervals over the entire contact surface. The length of the U-shaped profiles expediently corresponds to the length of a side edge of the contact surface.
Besonders bevorzugt berühren die beiden U-förmigen Profile eines Paares einander. Unter berühren wird hier verstanden, dass die U-förmigen Profile im Rahmen der Fertigungstoleranzen derart auf den Kontaktflächen angeordnet werden, dass zwischen gegenüberliegenden langen Seiten des U der U-förmigen Profile eines Paares maximal ein kleiner Spalt entsteht.Particularly preferably, the two U-shaped profiles of a pair touch each other. Under touch is understood here that the U-shaped profiles are arranged in the context of manufacturing tolerances on the contact surfaces such that between opposite long sides of the U of the U-shaped profiles of a pair a maximum gap is formed.

Auf jeder Kontaktfläche wird mindestens ein Hohlprofil derart angeordnet, dass man durch die Öffnung eines Hohlprofils auf einer Kontaktfläche in die Öffnung des Hohlprofils auf der anderen Kontaktfläche sieht, mit dem das Hohlprofil der einen Kontaktfläche ein Paar bildet. In den derart entstehenden Hohlraum wird ein weiteres Formteil eingefügt. Durch dieses weitere Formteil wird die Bewegung der beiden Kontaktflächen senkrecht zu den Kontaktflächen verhindert.In this embodiment of the invention hollow sections are arranged as a pair such that the openings of the hollow sections lie in a line. On each contact surface at least one hollow profile is arranged such that one sees through the opening of a hollow profile on a contact surface in the opening of the hollow profile on the other contact surface with which forms the hollow profile of a contact surface a pair. In the resulting cavity another molding is inserted. By this further molding, the movement of the two contact surfaces is prevented perpendicular to the contact surfaces.
Vorteilhafterweise werden mehrere Paare von Hohlprofilen hintereinander in einer Linie parallel zu einer Seitenkante der Kontaktflächen angeordnet. Bevorzugt wird ein weiteres Formteil in die Hohlräume von mehreren auf einer Linie angeordneter Paare von Hohlprofilen eingepasst. Besonders bevorzugt ist eine Vielzahl von mehreren auf einer Linie angeordneten Paaren in parallelen Linien regelmäßig über die Kontaktflächen verteilt. Die Querschnitte der Hohlräume der Hohlprofile können dabei eine beliebige geometrische Form, insbesondere Rechteck, Dreieck, Vieleck, Kreis oder Ellipse, aufweisen. Dabei können die Querschnitte auch zwischen in verschiedenen Linien angeordneten Hohlprofilen wechseln. Die zusätzlichen Formteile, die in die Hohlräume des jeweiligen Paares von Hohlprofilen eingepasst werden, weisen zweckmäßigerweise eine Form auf, die dem Querschnitt des Hohlraums entspricht.Advantageously, several pairs of hollow profiles are arranged behind one another in a line parallel to a side edge of the contact surfaces. Preferably, a further molded part is fitted into the cavities of a plurality of pairs of hollow profiles arranged on a line. Particularly preferably, a multiplicity of several pairs arranged in a line are regularly distributed over the contact surfaces in parallel lines. The cross sections of the cavities of the hollow profiles may have any geometric shape, in particular rectangle, triangle, polygon, circle or ellipse. The cross sections can also change between arranged in different lines hollow sections. The additional molded parts, which are fitted into the cavities of the respective pair of hollow profiles, expediently have a shape which corresponds to the cross section of the cavity.
In einer bevorzugten Ausgestaltung der Erfindung ist auf jeder Kontaktfläche mindestens ein Rohrstück befestigt, wobei die Rohrstücke derart angeordnet sind, dass mindestens ein auf einer Kontaktfläche befestigtes Rohrstück mit einem auf der anderen Kontaktfläche befestigten Rohrstück ein Paar bildet, wobei die Öffnung der Rohrstücke eines Paares in einer geraden Linie derart angeordnet sind, so dass ein weiteres Formteil in die beiden Öffnungen der Rohrstücke eines Paares eingefügt werden kann.In a preferred embodiment of the invention, at least one pipe piece is mounted on each contact surface, wherein the pipe pieces are arranged such that at least one piece of pipe fastened on one contact surface forms a pair with a pipe piece fixed on the other contact surface, the opening of the pipe pieces of a pair in a straight line are arranged so that another molding can be inserted into the two openings of the pipe pieces of a pair.

Das in den vorhergehenden Absätzen Geschilderte gilt hier entsprechend.In this embodiment of the invention pipe section are preferably used analogously to the hollow profiles of the preceding embodiment. The description in the preceding paragraphs applies accordingly.
Vorteilhafterweise berühren sich die Hohlprofile oder Rohrstücke eines Paares an der Stirnseite. Unter berühren wird hier verstanden, dass die Hohlprofile oder Rohrstücke im Rahmen der Fertigungstoleranzen derart auf den Kontaktflächen angeordnet werden, dass zwischen gegenüberliegenden Stirnseiten der Hohlprofile oder Rohrstücke eines Paares maximal ein kleiner Spalt entsteht.Advantageously, the hollow profiles or pipe sections of a pair touch on the front side. Under touch is understood here that the hollow sections or pipe sections are arranged in the context of manufacturing tolerances on the contact surfaces, that between the opposite end faces of the hollow sections or pipe sections of a pair a maximum gap is formed.
Zweckmäßigerweise ist das weitere Formteil eine Stange mit entsprechender Länge und entsprechendem rechteckigen, vieleckigen, dreieckigen oder runden Querschnitt.Conveniently, the further molded part is a rod with a corresponding length and corresponding rectangular, polygonal, triangular or round cross-section.
In einer weiteren Ausgestaltung der Erfindung ist auf jeder Kontaktfläche mindestens ein U-förmiges Profilstück als Formteil mit einer Seitenkante des U-förmigen Profils auf einer Kontaktfläche befestigt, wobei die U-förmigen Profile derart angeordnet sind, dass ein auf einer Kontaktfläche befestigtes U-förmiges Profil mit einem auf der anderen Kontaktfläche befestigten U-förmigen Profil ein Paar bildet, wobei die beiden U-förmigen Profile eines Paares derart angeordnet sind, dass sich die freie Seitenkante des einen U-förmigen Profils in der Öffnung des anderen U-förmigen Profils befindet.In a further embodiment of the invention, at least one U-shaped profile piece is fixed on each contact surface as a molded part with a side edge of the U-shaped profile on a contact surface, wherein the U-shaped profiles are arranged such that a fixed on a contact surface U-shaped Profile with a U-shaped profile attached to the other contact surface forms a pair, wherein the two U-shaped profiles of a pair are arranged such that the free side edge of a U-shaped profile is in the opening of the other U-shaped profile ,
In dieser Ausgestaltung der Erfindung wird die Bewegung der Kontaktflächen senkrecht zur Kontaktfläche durch Ausformung und Anordnung der Formteile selbst verhindert. Ein weiteres Formteil ist nicht notwendig. Die U-förmigen Profile sind in dieser Ausgestaltung paarweise derart angeordnet, dass sich jeweils die nicht auf einer Kontaktfläche befestigte lange Seite des U eines U-förmigen Profils in der Öffnung des zugehörigen, auf der anderen Kontaktfläche befestigten, U-förmigen Profils des Paares befindet. Das auf einer Kontaktfläche befestigte U-förmige Profil bildet sozusagen eine Führungsschiene für die lange Seite des U eines auf der anderen Kontaktfläche befestigten U-förmigen Profils und umgekehrt. Oder anders ausgedrückt, die beiden U-förmigen Profile eines Paares greifen ineinander. Auf diese Weise wird die Bewegung entlang der kurzen Seite des U eines U-förmigen Profils und somit die Bewegung senkrecht zur Kontaktfläche verhindert.In this embodiment of the invention, the movement of the contact surfaces is prevented perpendicular to the contact surface by molding and arrangement of the moldings themselves. Another molding is not necessary. The U-shaped profiles are arranged in pairs in this embodiment, that in each case the not fixed to a contact surface long side of the U of a U-shaped profile in the opening of the associated, mounted on the other contact surface, U-shaped profile of the pair , The fixed on a contact surface U-shaped profile forms, so to speak, a guide rail for the long side of the U of a mounted on the other contact surface U-shaped profile and vice versa.

In this way, the movement along the short side of the U of a U-shaped profile and thus the movement perpendicular to the contact surface is prevented.
Bevorzugt berühren die beiden U-förmigen Profile eines Paares einander. Unter berühren wird hier verstanden, dass die U-förmigen Profile im Rahmen der Fertigungstoleranzen derart auf den Kontaktflächen angeordnet werden, dass zwischen benachbarten Seiten des U der U-förmigen Profile eines Paares maximal ein kleiner Spalt entsteht. Ebenso werden vorteilhafterweise auch in dieser Ausgestaltung der Erfindung mehrere U-förmige Profile als Paare auf den Kontaktflächen angeordnet, wobei die Anordnung bevorzugt parallel und in regelmäßigen Abständen über die gesamte Kontaktfläche verteilt erfolgt. Die Länge der U-förmigen Profile entspricht zweckmäßigerweise der Länge einer Seitenkante der Kontaktfläche.Preferably, the two U-shaped profiles of a pair touch each other.

The length of the U-shaped profiles expediently corresponds to the length of a side edge of the contact surface.
In einer weiteren Ausgestaltung der Erfindung ist auf jeder Kontaktfläche mindestens ein L-förmiges Profilstück als Formteil mit einer Seitenkante des L-förmigen Profils auf einer Kontaktfläche befestigt, wobei die L-förmigen Profile derart angeordnet sind, dass ein auf einer Kontaktfläche befestigtes L-förmiges Profil mit einem auf der anderen Kontaktfläche befestigten L-förmigen Profil ein Paar bildet, wobei die beiden L-förmigen Profile eines Paares derart angeordnet sind, dass das L des L-förmigen Profil auf dem Kopf stehend auf der Kontaktfläche befestigt ist und die beiden kurzen Seiten des L des L-förmigen Profils überlappen. Das auf einer Kontaktfläche befestigte L-förmige Profil bildet sozusagen eine Führungsschiene für die kurze Seite des L eines auf der anderen Kontaktfläche befestigten L-förmigen Profils und umgekehrt. Auf diese Weise wird die Bewegung entlang der langen Seite des L eines L-förmigen Profils und somit die Bewegung senkrecht zur Kontaktfläche verhindert.In a further embodiment of the invention, at least one L-shaped profile piece is fixed on each contact surface as a molded part with a side edge of the L-shaped profile on a contact surface, wherein the L-shaped profiles are arranged such that an attached to a contact surface L-shaped Profile forms a pair with an attached to the other contact surface L-shaped profile, wherein the two L-shaped profiles of a pair are arranged such that the L of the L-shaped profile is fixed upside down on the contact surface and the two short Overlap sides of the L of the L-shaped profile. The attached on a contact surface L-shaped profile forms, so to speak, a guide rail for the short side of the L of an attached to the other contact surface L-shaped profile and vice versa. In this way, the movement along the long side of the L of an L-shaped profile and thus the movement perpendicular to the contact surface is prevented.
Bevorzugt berühren die beiden L-förmigen Profile eines Paares einander. Unter berühren wird hier verstanden, dass die L-förmigen Profile im Rahmen der Fertigungstoleranzen derart auf den Kontaktflächen angeordnet werden, dass zwischen benachbarten Seiten des L der L-förmigen Profile eines Paares maximal ein kleiner Spalt entsteht. Ebenso werden vorteilhafterweise auch in dieser Ausgestaltung der Erfindung mehrere L-förmigen Profile als Paare auf den Kontaktflächen angeordnet, wobei die Anordnung bevorzugt parallel und in regelmäßigen Abständen über die gesamte Kontaktfläche verteilt erfolgt. Die Länge der L-förmigen Profile entspricht zweckmäßigerweise der Länge einer Seitenkante der Kontaktfläche.Preferably, the two L-shaped profiles of a pair touch each other. Under touch is understood here that the L-shaped profiles are arranged in the context of manufacturing tolerances on the contact surfaces, that between adjacent sides of the L of the L-shaped profiles of a pair a maximum gap is formed.

The length of the L-shaped profiles expediently corresponds to the length of a side edge of the contact surface.
Diese Ausgestaltung der Erfindung ähnelt der vorangegangenen Ausgestaltung, wobei hier L-förmige Profile statt U-förmigen Profile verwendet werden. Die beiden L-förmigen Profile eines Paares sind jeweils auf dem Kopf auf der entsprechenden Kontaktfläche befestigt. Die lange Seite des L ist somit senkrecht auf der Kontaktfläche stehend befestigt, während die kurze Seite des L parallel und beabstandet zur Kontaktfläche orientiert ist. In den dadurch entstehenden Hohlraum befindet sich jeweils die kurze Seite des L des anderen L-förmigen Profils des Paares. Die beiden L-förmigen Profile eines Paares greifen so quasi ineinander.This embodiment of the invention is similar to the previous embodiment, in which case L-shaped profiles are used instead of U-shaped profiles. The two L-shaped profiles of a pair are each mounted on the head on the corresponding contact surface. The long side of the L is thus fixed vertically standing on the contact surface, while the short side of the L is oriented parallel and spaced from the contact surface. In the resulting cavity is in each case the short Side of the L of the other L-shaped profile of the pair. The two L-shaped profiles of a pair almost interlock.
Die Bezeichnung kurze und lange Seite des L dient sich hier nur zur Erläuterung der Orientierung des L-förmigen Profiles. Beide Seiten können auch tatsächlich gleich lang oder mit umgekehrten Längenvehältnis sein.The term short and long side of the L is used here only to explain the orientation of the L-shaped profile. Both sides can actually be the same length or in reverse length.
Die oben genannten Ausgestaltungen der Erfindung können beliebig miteinander kombiniert werden. Die Kontaktflächen zweier Module eines Plattenwärmetauschers können sowohl Paare von U-förmigen Profilen, L-förmigen Profilen mit oder ohne zusätzliches Formteil, Hohlprofilen und/oder Rohrstücken aufweisen.The abovementioned embodiments of the invention can be combined as desired. The contact surfaces of two modules of a plate heat exchanger may have both pairs of U-shaped profiles, L-shaped profiles with or without additional molding, hollow sections and / or pipe sections.

Die U-förmigen Profile 20a werden mit einer Seitenkante 21 a des U-förmigen Profils über eine Schweiß- oder Lötverbindung 10 mit dem Deckblech 5 auf der Kontaktfläche 9a verschweißt oder verlötet. Analog werden die U-förmigen Profile 20b mit einer Seitenkante 21 b über eine Schweißverbindung 10 auf der Kontaktfläche 9b befestigt. Die U-förmigen Profile sind dabei so angeordnet, dass ihre Öffnungen 22a und 22b aufeinander zeigen und so den Hohlraum 23 bilden. In diesen Hohlraum wird eine Stange 50 mit einem rechteckigen Querschnitt eingepasst, die der Größe des Hohlraums 23 entspricht.The
Die beiden U-förmigen Profile 20a und 20b sind dabei derart auf den Kontaktflächen angeordnet, dass sie sich berühren. Berühren heißt im Rahmen dieser Anmeldung, dass sich im Rahmen der Fertigungstoleranzen derartiger Profile maximal ein kleiner Spalt zwischen den gegenüberliebenden Seiten 21 a und 21 b der U-förmigen Profile 20a und 20b bildet. Ebenso wird im Rahmen der Fertigungstoleranzen die Stange 50 in den Hohlraum 23 eingepasst, der durch die beiden U-förmigen Profile 20a und 20b eines Paares gebildet wird.The two
In dieser Ausgestaltung der Erfindung werden mehrere U-förmige Profile 20a, 20b regelmäßig über die beiden Kontaktflächen 9a und 9b verteilt, so dass der Zwischenraum zwischen den beiden Kontaktflächen 9a und 9b regelmäßig mit voneinander beabstandeten Profilpaaren ausgefüllt ist. Die U-förmigen Profile 20a, 20b sowie die rechteckigen Stangen 50 haben dabei eine Länge, die annähernd der Länge einer der Seitenkante der Kontaktflächen 9a, 9b entspricht.In this embodiment of the invention, a plurality of
Durch die zwischen die beiden U-förmigen Profile 20a, 20b eines Paares gesteckte Stange 50 wird die Bewegung der Module senkrecht zu den Kontaktflächen verhindert. Eine Bewegung in der Ebene der Kontaktflächen 9a, 9b wird in dieser Ausgestaltung der Erfindung ebenfalls verhindert.By the inserted between the two
Bei der Fertigung einer derartigen Ausgestaltung eines erfindungsgemäßen Plattenwärmetauschers werden als erstes die einzelnen U-förmigen Profile 20a und 20b auf die Deckbleche 5 der Module 1 a, 1 b geschweißt, die später die Kontaktflächen 9a und 9b bilden. Die beiden Module 1 a, 1 b werden dann an den Kontaktflächen zusammengefügt. Durch die auf den jeweiligen Kontaktflächen paarweise angeordneten U-förmigen Profile 20a, 20b entsteht dabei der Hohlraum 23 zwischen den U-förmigen Profilen 20a, 20b eines Paares. In diese Hohlräume 23 werden die rechteckigen Stangen 50 eingepasst und so die beiden Module 1 a und 1 b verbunden. Zusätzlich können die Module anschließend noch optional über Sidebars 8 an den Rändern, wie im Stand der Technik beschrieben, verschweißt werden.In the production of such a design of a plate heat exchanger according to the invention, the individual
Durch die Vielzahl der regelmäßig angeordneten Profilpaare 20a, 20b mit den entsprechenden rechteckigen Stangen 50 wird jedoch im Gegensatz zum Stand der Technik eine deutlich flächigere und somit mechanisch stabilere Verbindung zwischen den beiden Modulen 1 a und 1 b erreicht.Due to the large number of regularly arranged

Von diesen Linien werden mehrere Linien in regelmäßigen Abständen über die andere Seitenlänge der Kontaktflächen 9a, 9b verteilt, so dass die Kontaktflächen mit einer Vielzahl regelmäßig angeordneter Paare von Rohrstücken 30a, 30b ausgefüllt sind. In jede Linie hintereinander angeordneter Paare von Rohrstücken 30a, 30b wird eine entsprechende runde Stange 51 eingepasst, so dass die Öffnungen 31 a, 31 b der Rohrstücke 30a, 30b durch die Stange 51 gefüllt sind. D.h. in dieser Ausgestaltung der Erfindung ist der Querschnitt der Stange 51 derart gewählt, dass sich im Rahmen der Fertigungstoleranzen höchsten ein Spalt zwischen Stange 51 und innerer Wand der Rohrstücke 30a, 30b bildet.Also in this embodiment of the invention, a plurality of pairs of
