Description

Hintergrund der ErfindungBackground of the invention

Plattenwärmetauscher sind in verschiedenen Bauformen bekannt. Hierzu gehören insbesondere gedichtete, gelötete und geschweißte Plattenwärmetauscher. Gemeinsam ist den verschiedenen Bauarten üblicherweise, dass eine gestapelte Anordnung mit einer vorderseitigen und einer rückseitigen Endplatte gebildet ist, zwischen denen mehrere Wärmetauscherplatten aufgenommen und gestapelt sind, derart, dass zwischen den Wärmetauscherplatten Hohlräume gebildet sind, die im Betrieb mehrere Wärmetauschermedien oder -fluide aufnehmen. Üblicherweise werden die Hohlräume von den Wärmetauschermedien durchströmt.Plate heat exchangers are known in various designs. These include in particular sealed, soldered and welded plate heat exchangers. Common to the various types is commonly that a stacked arrangement is formed with a front and a rear end plate between which a plurality of heat exchanger plates are received and stacked, such that between the heat exchanger plates cavities are formed, which receive several heat exchange media or fluids in operation. Usually, the cavities are flowed through by the heat exchange media.

Während bei der gelöteten und der geschweißten Ausführung ein Abdichten der Hohlräume mittels Löt- oder Schweißverbindung erfolgt, sind bei Plattenwärmetauschern in gedichteter Ausführung Dichtungselemente vorgesehen, die in der gestapelten Anordnung die Hohlräume abdichtend angeordnet sind. Gedichtete Plattenwärmetauscher weisen sodann eine Spannvorrichtung auf, die konfiguriert ist, die gestapelte Anordnung mit Endplatten und Wärmetauscherplatten sowie Dichtungselementen vorzuspannen, indem mit Hilfe der Spannvorrichtung ein äußerer Spanndruck aufgegeben wird. Fig. 1 zeigt eine perspektivische Darstellung eines bekannten Plattenwärmetauschers in gedichteter Ausführung, bei dem zwischen zwei Druckgestellplatten 1, 2 ein Stapel 3 mit Wärmetauscherplatten angeordnet ist. Die Spannvorrichtung zum Vorspannen der gestapelten Anordnung ist mit Zugstangen 4 gebildet, die in übergreifenden Bereichen 5 die beiden Endplatten 1, 2 verbinden. Die Zugstangen 4 sind mit Schraubgewinde versehen, so dass ein äußerer Druck einstellbar ist.While in the soldered and welded design, sealing of the cavities by means of soldering or welding connection is provided in plate seal exchangers in a sealed design sealing elements which are sealingly arranged in the stacked arrangement, the cavities. Gasketed plate heat exchangers then include a chuck configured to bias the stacked assembly with end plates and heat exchanger plates and sealing members by applying an external clamping pressure with the aid of the chuck. Fig. 1 shows a perspective view of a known plate heat exchanger in a sealed design, in which between two printing frame plates 1, 2, a stack 3 is arranged with heat exchanger plates. The tensioning device for biasing the stacked arrangement is formed with tie rods 4 which connect the two end plates 1, 2 in overlapping areas 5. The tie rods 4 are provided with screw thread, so that an external pressure is adjustable.

Zusammenfassung der ErfindungSummary of the invention

Aufgabe der Erfindung ist es, einen verbesserten Plattenwärmetauscher in gedichteter Ausführung zu schaffen, welcher kostengünstiger und mit optimierter Bauform herstellbar ist.The object of the invention is to provide an improved plate heat exchanger in a sealed design, which is less expensive and can be produced with optimized design.

Diese Aufgabe wird erfindungsgemäß durch einen Plattenwärmetauscher in gedichteter Ausführung nach dem unabhängigen Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand von abhängigen Unteransprüchen.This object is achieved by a plate heat exchanger in a sealed version according to the independent claim 1. Advantageous embodiments of the invention are the subject of dependent subclaims.

Die Erfindung umfasst den Gedanken eines Plattenwärmetauschers in gedichteter Ausführung mit einer gestapelten Anordnung und einer Spannvorrichtung, die konfiguriert ist, die gestapelte Anordnung zum Spannen mit einem äußeren Spanndruck zu beaufschlagen, wobei die gestapelte Anordnung eine vorder- und eine rückseitige Endplatte, von denen wenigstens eine Endplatte als eine Anschlussplatte ausgeführt ist, Wärmetauscherplatten, die zwischen der vorder- und der rückseitigen Endplatte aufgenommen und gestapelt sind, derart, dass zwischen den Wärmetauscherplatten Hohlräume zum Aufnehmen mehrerer Wärmetauschermedien gebildet sind, und Dichtungselemente aufweist, die die Hohlräume abdichtend angeordnet sind, und wobei die Spannvorrichtung die gestapelte Anordnung zumindest abschnittsweise, nämlich wenigstens in einem Eckbereich der gestapelten Anordnung, formschlüssig umgreifend gebildet ist.The invention contemplates the concept of a sealed plate heat exchanger having a stacked arrangement and a fixture configured to bias the stacked assembly to an external clamping pressure for clamping, the stacked assembly including front and rear end plates, at least one of which End plate is designed as a connection plate, heat exchanger plates, which are received and stacked between the front and the rear end plate, such that between the heat exchanger plates cavities for receiving a plurality of heat exchange media are formed, and sealing elements, which are arranged to seal the cavities, and wherein the clamping device, the stacked arrangement at least in sections, namely at least in a corner region of the stacked arrangement, form-fitting encompassing is formed.

Der Querschnitt der Spannvorrichtung auf der Innenseite, nämlich der der gestapelten Anordnung zugewandten Seite, ist im Rahmen üblicher Fertigungstoleranzen zumindest in dem wenigstens einen Eckbereich an die äußere Kontur der gestapelten Anordnung angepasst. Es kann auch vorgesehen sein, dass die Formschlüssigkeit in mehreren oder sogar allen Eckbereichen ausgebildet ist. Letzteres ist zum Beispiel gegeben, wenn die Spannvorrichtung die gestapelte Anordnung vollständig formschlüssig umgreifend gebildet ist.The cross section of the clamping device on the inside, namely the side facing the stacked arrangement, is adapted to the outer contour of the stacked arrangement, at least in the at least one corner region, within the scope of customary manufacturing tolerances. It can also be provided that the positive engagement is formed in several or even all corner regions. The latter is given, for example, when the clamping device, the stacked arrangement is formed completely encompassing form-fitting manner.

Eine bevorzugte Ausbildung der Erfindung kann vorsehen, dass die Spannvorrichtung in dem wenigstens einen formschlüssig umgriffenen Abschnitt der gestapelten Anordnung im Wesentlichen durchgehend auf der äußeren Oberfläche eines zugeordneten Abschnitts der gestapelten Anordnung aufliegt.A preferred embodiment of the invention may provide that the clamping device rests substantially continuously on the outer surface of an associated portion of the stacked arrangement in the at least one form-fitting embraced portion of the stacked arrangement.

Mit Hilfe des vorgeschlagenen Plattenwärmetauschers ist zunächst ein Wärmetauscher geschaffen, der im Vergleich zum Stand der Technik eine geringere Baugröße aufweist, da es nicht notwendig ist, Zugstangen seitlich an den gestapelten Wärmetauscherplatten vorbeizuführen, um seitlich überstehende Abschnitte der Endplatten für die Spannvorrichtung zu verbinden. Vielmehr umgreift die Spannvorrichtung wenigstens in einem Eckbereich die gestapelte Anordnung formschlüssig, so dass hier seitlich der gestapelten Anordnung ein verminderter oder sogar gar kein Platzbedarf besteht, insbesondere für Spannelemente.With the aid of the proposed plate heat exchanger, a heat exchanger is first provided which has a smaller size compared to the prior art, since it is not necessary to pass tie rods laterally past the stacked heat exchanger plates to connect laterally projecting portions of the end plates for the tensioning device. Rather, the clamping device surrounds the stacked at least in a corner region Arrangement form-fitting, so that here the side of the stacked arrangement a reduced or even no space is required, especially for clamping elements.

Eine bevorzugte Ausführungsform der Erfindung sieht vor, dass die Spannvorrichtung mit einem oder mehreren geschlossenen Profilelementen und / oder einem oder mehreren flexiblen Spannbändern gebildet ist, die die gestapelte Anordnung jeweils umgreifen. Die Spannbänder sind bevorzugt aus einem Material aus der Gruppe der folgenden Materialien gebildet: Stahl, Kunststoffe und thermoplastische Stoffe. Bei der Herstellung des Plattenwärmetauschers werden das eine oder die mehreren Spannbänder mittels mechanischen Spannens und / oder Aufschrumpfens auf die gestapelten Anordnung aufgezogen.A preferred embodiment of the invention provides that the tensioning device is formed with one or more closed profile elements and / or one or more flexible tension bands, which respectively embrace the stacked arrangement. The straps are preferably formed from one of the following materials: steel, plastics and thermoplastics. In the manufacture of the plate heat exchanger, the one or more straps are mounted on the stacked assembly by means of mechanical tensioning and / or shrinking.

Das eine oder die mehreren geschlossenen Profilelemente können beispielsweise als ein Vierkantprofil oder -rohr gebildet sein. Profilelemente in dieser oder anderen Ausführungsformen stehen als solche in unterschiedlichen Varianten kostengünstig zur Verfügung. Auf diese Weise werden die Herstellungskosten insgesamt minimiert.The one or more closed profile elements may for example be formed as a square profile or tube. Profile elements in this or other embodiments are available as such in different variants at low cost. In this way, the manufacturing costs are minimized overall.

Bei der Herstellung des Plattenwärmetauschers werden das eine oder die mehreren geschlossenen Profilelemente von der Stirnseite auf die gestapelte Anordnung mit Endplatten und hierzwischen angeordneten Wärmetauscherplatten aufgeschoben. Dieses geschieht bei wenigstens einseitig noch nicht montierten Anschlüssen. Die Anschlüsse können dann nach dem Aufschieben des einen oder der mehreren geschlossenen Profilelemente montiert werden.In the production of the plate heat exchanger, the one or more closed profile elements are slid from the end face to the stacked arrangement with end plates and heat exchanger plates arranged therebetween. This happens in at least one side not yet mounted connections. The terminals can then be mounted after sliding the one or more closed profile elements.

Eine bevorzugte Weiterbildung der Erfindung sieht vor, dass die Spannvorrichtung mit einem durchgehenden geschlossenen Profilelement gebildet ist, welches sich die gestapelte Anordnung umgreifend über einen Bereich von wenigstens 50% der Länge des Abschnittes der gestapelten Anordnung zwischen Anschlüssen an der Anschlussplatte erstreckt. Bei dieser Ausführungsform bildet das durchgehende geschlossene Profilelement eine Art "Bauchbinde" im Bereich der gestapelten Anordnung zwischen den Anschlüssen. Eine bevorzugte Weiterbildung sieht vor, dass sich das durchgehende geschlossene Profilelement über einen Bereich von wenigstens 75% der Länge der gestapelten Anordnung zwischen den Anschlüssen erstreckt. Weiter bevorzugt ist, dass das durchgehende geschlossene Profilelement eine Länge von wenigstens 90% des Bereiches zwischen den Anschlüssen erfasst. Der Abschnitt der gestapelten Anordnung zwischen den Anschlüssen kann ganz oder teilweise von einem oder mehreren geschlossenen Profilelementen umgriffen sein.A preferred development of the invention provides that the clamping device is formed with a continuous closed profile element, which extends around the stacked arrangement encompassing over a range of at least 50% of the length of the portion of the stacked arrangement between terminals on the connection plate. In this embodiment, the continuous closed profile element forms a kind of "belly band" in the region of the stacked arrangement between the terminals. A preferred embodiment provides that the continuous closed profile element extends over a range of at least 75% of the length of the stacked arrangement between the terminals. It is further preferred that the continuous closed profile element covers a length of at least 90% of the area between the terminals. The section of the stacked Arrangement between the terminals may be wholly or partially surrounded by one or more closed profile elements.

Eine bevorzugte Ausführungsform der Erfindung sieht vor, dass die Spannvorrichtung mit einem durchgehenden geschlossenen Profilelement gebildet ist, welches sich die gestapelte Anordnung umgreifend über die gesamte Länge des Plattenwärmetauschers erstreckt.A preferred embodiment of the invention provides that the clamping device is formed with a continuous closed profile element, which extends around the entire length of the plate heat exchanger, the stacked arrangement.

Eine vorteilhafte Ausführungsform der Erfindung sieht vor, dass das eine oder die mehreren geschlossenen Profilelemente aus einem Normprofilelement gebildet sind. Die Verwendung von Normprofilelementen unterstützt eine weitere Kostenreduzierung, da derartige Profilelemente als häufig hergestellte Produkte in verschiedenen Bauformen kostengünstig zur Verfügung stehen.An advantageous embodiment of the invention provides that the one or more closed profile elements are formed from a standard profile element. The use of standard profile elements supports a further cost reduction, since such profile elements are available as frequently produced products in various designs at low cost.

Bevorzugt sieht eine Fortbildung der Erfindung vor, dass Wandabschnitte des einen oder der mehreren geschlossenen Profilelemente als Fachprofile gebildet sind. Eine flache Bauform der Wandabschnitte der geschlossenen Profilelemente unterstützt weiter den minimierten Raumbedarf des Plattenwärmetauschers.Preferably, a further development of the invention provides that wall sections of the one or more closed profile elements are formed as compartment profiles. A flat design of the wall sections of the closed profile elements further supports the minimized space requirement of the plate heat exchanger.

Bei einer vorteilhaften Ausgestaltung der Erfindung kann vorgesehen sein, dass die Spannvorrichtung mit einstellbaren Vorspannelementen gebildet ist, die an dem einen der mehreren geschlossenen Profilelemente angeordnet sind. Die einstellbaren Vorspannelemente sind beispielsweise mit Hilfe von Schraubenelementen gebildet, die in zugeordneter Gewindeabschnitte in dem einen oder den mehreren geschlossenen Profilelementen eingeschraubt werden. Die Schraubenelemente können dann so weit eingedreht werden, dass sie schließlich gegen die gestapelte Anordnung drücken. Bevorzugt sind derartige Schraubenelemente nur auf der Vorder- oder nur auf der Rückseite der gestapelten Anordnung an den geschlossenen Profilelementen vorgesehen. Auf der gegenüberliegenden Seite wird die gestapelte Anordnung dann flächig gegen die Innenseite des geschlossenen Profilelementes gedrückt.In an advantageous embodiment of the invention can be provided that the clamping device is formed with adjustable biasing elements, which are arranged on the one of the several closed profile elements. The adjustable biasing elements are formed, for example, by means of screw elements which are screwed in associated threaded portions in the one or more closed profile elements.

Preferably, such screw elements are provided only on the front or only on the back of the stacked arrangement of the closed profile elements. On the opposite side, the stacked arrangement is then pressed flat against the inside of the closed profile element.

Eine Weiterbildung der Erfindung kann vorsehen, dass die einstellbaren Vorspannelemente konfiguriert sind, den äußeren Spanndruck auf die gestapelte Anordnung einzuleiten, vorzugsweise im Wesentlichen mittelsymmetrisch.A development of the invention may provide that the adjustable biasing elements are configured to initiate the external clamping pressure on the stacked arrangement, preferably substantially symmetrically.

Bei einer zweckmäßigen Ausgestaltung der Erfindung kann vorgesehen sein, dass die einstellbaren Vorspannelemente an einem oder allen geschlossenen Profilelementen in Querrichtung der gestapelten Anordnung beabstandet voneinander gebildet sind.In an expedient embodiment of the invention it can be provided that the adjustable biasing elements are formed at one or all closed profile elements in the transverse direction of the stacked arrangement spaced from each other.
