Description

Die vorliegende Erfindung betrifft einen Plattenwärmetauscher mit einer Deckplatte, einer Grundplatte und dazwischen stapelartig angeordneten Wärmetauscherplatten gemäß dem Oberbegriff des Anspruchs 1. Die Erfindung betrifft außerdem eine Grundplatte für einen derartigen Plattenwärmetauscher sowie ein Verfahren zur Herstellung desselben.The present invention relates to a plate heat exchanger having a cover plate, a base plate and arranged therebetween stacked heat exchanger plates according to the preamble of claim 1. The invention also relates to a base plate for such a plate heat exchanger and a method for producing the same.

Aus der DE 10 2009 030 095 A1 ist ein gattungsgemäßer Plattenwärmetauscher für einen Verbrennungsmotor bekannt, der eine Mehrzahl von aufeinander in einem Stapel angeordnete Wärmetauscherplatten und eine am Ende dieses Stapels angeordnete Grundplatte umfasst. Die Grundplatte weist dabei einen in Richtung des Stapels aufgestellten Rand auf, der zumindest abschnittsweise einem Umriss des Stapels folgt.From the DE 10 2009 030 095 A1 a generic plate heat exchanger for an internal combustion engine is known, comprising a plurality of successively arranged in a stack heat exchanger plates and arranged at the end of this stack base plate. The base plate has a raised in the direction of the stack edge, which at least partially follows an outline of the stack.

Aus der DE 10 2006 005 106 A1 ist ein weiterer Plattenwärmetauscher mit einer Grundplatte bekannt, der in einem Gehäuse angeordnet ist, in das Ladeluft einströmt. Das Gehäuse besitzt eine Montageöffnung, in die der Plattenwärmetauscher einsetzbar und mit einer Grundplatte zu befestigen ist, wobei der Plattenwärmetauscher im Inneren des Gehäuses zusätzlich befestigt ist. Diese Verbindung soll dadurch verbessert werden, dass im Inneren des Gehäuses zwischen zwei Endkammern eine Leiste ausgebildet ist, die sich über wenigstens einen wesentlichen Teil der Endkammerlänge erstreckt.From the DE 10 2006 005 106 A1 is another plate heat exchanger with a base plate is known, which is arranged in a housing, flows into the charge air. The housing has a mounting opening into which the plate heat exchanger can be used and attached to a base plate, wherein the plate heat exchanger is additionally mounted inside the housing. This connection is to be improved in that a bar is formed in the interior of the housing between two end chambers, which extends over at least a substantial part of the Endkammerlänge.

Aus der EP 0 623 798 A2 ist ebenfalls ein Plattenwärmetauscher, insbesondere in der Bauart eines Ölkühlers, bekannt, der aufeinander gestapelte, wannenförmige Wärmetauscherplatten besitzt, deren umlaufende Ränder aneinander anliegen und dicht miteinander verlötet sind, wobei sämtliche Wärmetauscherplatten die gleiche Form aufweisen. Durch die Verwendung von speziellen Ausführungsformen, bei denen turbulenzerzeugende Erhebungen bzw. abdichtende Ausprägungen in die Wärmetauscherplatten eingearbeitet sind, wird die Anzahl der Einbauteile, zum Beispiel der Turbulenzeinlagen, verringert.From the EP 0 623 798 A2 is also a plate heat exchanger, in particular in the design of an oil cooler, known which has stacked, trough-shaped heat exchanger plates, the peripheral edges abut each other and are sealed together, all heat exchanger plates have the same shape. By using special embodiments, in which turbulence-generating elevations or sealing characteristics are incorporated into the heat exchanger plates, the number of built-in parts, for example, the turbulence inserts, is reduced.

Die vorliegende Erfindung beschäftigt sich mit dem Problem, für einen Plattenwärmetauscher der gattungsgemäßen Art eine verbesserte oder zumindest eine alternative Ausführungsform anzugeben, die insbesondere einfach zu fertigen ist und weniger Gewicht aufweist.The present invention addresses the problem of providing for a plate heat exchanger of the generic type an improved or at least one alternative embodiment which is particularly easy to manufacture and has less weight.

Dieses Problem wird erfindungsgemäß durch die Gegenstände der unabhängigen Ansprüche gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This problem is solved according to the invention by the subject matters of the independent claims. Advantageous embodiments are the subject of the dependent claims.

Die vorliegende Erfindung beruht auf dem allgemeinen Gedanken, bei einem an sich bekannten Plattenwärmetauscher, beispielsweise einem Ölkühler, mit einer Deckplatte, einer Grundplatte und dazwischen stapelartig angeordneten Wärmetauscherplatten, die Grundplatte, über welche der Plattenwärmetauscher mit einem weiteren Bauteil, beispielsweise einem Verbrennungsmotor, verbindbar ist, nicht wie bisher massiv und dadurch schwer auszubilden, sondern aus zumindest zwei miteinander verbundenen und vergleichsweise leichten Platten aufzubauen. Durch den zumindest zweilagigen Aufbau der erfindungsgemäßen Grundplatte wird diese im Vergleich zu bisher aus dem Stand der Technik bekannten Grundplatten deutlich leichter, was insbesondere im Hinblick auf einen Kraftstoffverbrauch von großem Vorteil ist. Die erste Platte kann dabei plan aufgebaut sein, wogegen die zweite Platte Erhebungen aufweist. Die Erhebungen sind dabei in Richtung der benachbarten Wärmetauscherplatte orientiert und bilden dadurch Positionierhilfen für diese. Ein Rand zwischen den beiden Platten der Grundplatte ist offen ausgebildet, um die beim flächigen Verlöten der beiden Platten auftretende Luft entweichen lassen zu können. Die Erhebungen bilden gleichzeitig Aussteifungselemente, die der Grundplatte eine gesteigerte Festigkeit, insbesondere auch eine gesteigerte Biegesteifigkeit, verleihen.The present invention is based on the general idea, in a known plate heat exchanger, such as an oil cooler, with a cover plate, a base plate and heat exchanger plates stacked therebetween, the base plate, via which the plate heat exchanger with another component, such as an internal combustion engine, connectable , not massively and thus hard to train as before, but build from at least two interconnected and relatively light plates. Due to the at least two-layer construction of the base plate according to the invention this is much easier compared to previously known from the prior art base plates, which is particularly in terms of fuel consumption of great advantage. The first plate can be constructed plan, whereas the second plate has elevations. The elevations are oriented in the direction of the adjacent heat exchanger plate and thereby form positioning aids for them. An edge between the two plates of the base plate is designed to be open in order to allow the air occurring during surface soldering of the two plates to escape. The surveys form at the same time Stiffening elements, which give the base plate increased strength, in particular an increased flexural rigidity.

Von besonderem Vorteil ist darüber hinaus, dass eine erste Wärmetauscherplatte des Plattenwärmetauschers nun nicht mehr flächig mit der Grundplatte verlötet wird, sondern nur noch linienförmig umlaufend am Rand und mittig über eine dort angeordneten Turbulenzkontur, wodurch auch der Fertigungsprozess insgesamt optimiert werden kann, da insbesondere weniger Lot erforderlich ist. Durch den Wegfall der bisher erforderlichen flächigen Verlötung können insbesondere auch nur schwer handhabbare Verziehungen bzw. Verwerfungen eliminiert werden, die in dieser Form bei einer linienförmigen Verlötung nicht mehr auftreten.Of particular advantage is also that a first heat exchanger plate of the plate heat exchanger is no longer soldered surface to the base plate, but only linearly circumferentially at the edge and centrally over a turbulence contour arranged there, whereby the manufacturing process can be optimized as a whole, especially less Lot is required. By eliminating the previously required planar soldering, it is also possible in particular to eliminate distortions or distortions which are difficult to handle and which no longer occur in this form in the case of linear soldering.

Bei einer vorteilhaften Ausführungsform der erfindungsgemäßen Lösung sind die zumindest zwei miteinander zur Grundplatte verbundenen Platten aus Aluminium ausgebildet und mittels eines Aluminiumlots miteinander verlötet. Durch die Ausbildung der beiden Platten als Aluminiumplatten können diese zusätzlich besonders leicht ausgebildet werden, was ebenfalls vorteilhaft in Bezug auf eine Gewichtsoptimierung und eine damit verbundene Kraftstoffeinsparung ist. Generell können die beiden Platten eine Dicke von ca. 0,5 bis ca. 1,0 mm aufweisen, so dass eine gesamte Materialstärke von nur ca. 1,5 mm für die Grundplatte erforderlich ist, was im Vergleich zu bisher massiven Grundplatten mit einer Dicke von ca. 5 mm eine erhebliche Material- und Gewichtseinsparung bedeutet. Zudem besitzt die erfindungsgemäß gebaute Grundplatte eine gesteigerte Steifigkeit/Festigkeit. Neben der bereits im vorherigen Absatz erwähnten Gewichtseinsparung ist die mit dem erfindungsgemäßen Plattenwärmetauscher und der erfindungsgemäßen Grundplatte erzielbare Materialeinsparung ebenfalls von besonderem Vorteil, da die erfindungsgemäße Grundplatte weniger als 50 %, vorzugsweise sogar weniger als 40 % des Materials einer bisherigen Grundplatte bedarf. Im Hinblick auf stetig steigende Rohstoffpreise, insbesondere auch für Aluminium, kann so der erfindungsgemäße Plattenwärmetauscher kostengünstiger hergestellt werden.In an advantageous embodiment of the solution according to the invention, the at least two plates connected to the base plate are formed of aluminum and soldered together by means of an aluminum solder. The design of the two plates as aluminum plates, these can also be particularly easily formed, which is also advantageous in terms of weight optimization and associated fuel economy. Generally, the two plates can have a thickness of about 0.5 to about 1.0 mm, so that a total material thickness of only about 1.5 mm is required for the base plate, which compared to previously massive base plates with a Thickness of about 5 mm means a significant material and weight savings. In addition, the base plate according to the invention has an increased rigidity / strength. In addition to the already mentioned in the previous paragraph weight saving achievable with the plate heat exchanger and the base plate according to the invention material saving is also of particular advantage, since the base plate of the invention requires less than 50%, preferably even less than 40% of the material of a previous base plate. In view of steadily rising raw material prices, especially for Aluminum, so the plate heat exchanger according to the invention can be produced more cheaply.

Zweckmäßig weisen die einzelnen Wärmetauscherplatten Turbulenzkonturen auf, über welche diese vorzugsweise punktförmig miteinander verlötet sind. Die Turbulenzkonturen bewirken ein gleichmäßiges und zugleich turbulentes Durchströmen der einzelnen Wärmetauscherplatten entweder mit Kühlmittel oder mit zu kühlendem Fluid, beispielsweise Öl, wobei durch die Verlötung der einzelnen Wärmetauscherplatten über sich berührende Turbulenzkonturen der Plattenwärmetauscher insgesamt besonders steif und dadurch auch robust ausgebildet werden kann.The individual heat exchanger plates expediently have turbulence contours over which they are preferably soldered to one another in a punctiform manner. The turbulence contours cause a uniform and at the same time turbulent flow through the individual heat exchanger plates either with coolant or with fluid to be cooled, for example oil, which can be formed by the soldering of the individual heat exchanger plates on touching turbulence contours of the plate heat exchanger as a whole particularly stiff and therefore also robust.

Weitere wichtige Merkmale und Vorteile der Erfindung ergeben sich aus den Unteransprüchen, aus den Zeichnungen und aus der zugehörigen Figurenbeschreibung anhand der Zeichnungen.Other important features and advantages of the invention will become apparent from the dependent claims, from the drawings and from the associated figure description with reference to the drawings.

Es versteht sich, dass die vorstehend genannten und die nachstehend noch zu erläuternden Merkmale nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen oder in Alleinstellung verwendbar sind, ohne den Rahmen der vorliegenden Erfindung zu verlassen.It is understood that the features mentioned above and those yet to be explained below can be used not only in the particular combination given, but also in other combinations or in isolation, without departing from the scope of the present invention.

Entsprechend der Fig. 1, weist ein erfindungsgemäßer Plattenwärmetauscher 1, der beispielsweise als Ölkühler ausgebildet sein kann, eine Deckplatte 2, eine gebaute Grundplatte 3 sowie eine Mehrzahl dazwischen stapelartig angeordneter Wärmetauscherplatten 4 auf, die über Ränder 5 (vgl. Fig. 5 und 6) umlaufend fluiddicht miteinander verlötet sind. Der Plattenwärmetauscher 1 ist dabei über dessen Grundplatte 3 mit einem weiteren Bauteil, beispielsweise mit einem Verbrennungsmotor, verbindbar, wobei in der Grundplatte 3 entsprechende Ver-/Entsorgungsöffnungen oder -leitungen angeordnet sein können. Erfindungsgemäß ist nun die Grundplatte 3 als gebaute Grundplatte 3 ausgebildet und aus zumindest zwei miteinander verbundenen Platten 6 und 7 (vgl. auch Fig. 2) aufgebaut. Die beiden Platten 6, 7 der Grundplatte 3 sind flächig miteinander verlötet, wobei die erste Platte 6 plan ausgebildet ist und die zweite Platte 7 Erhebungen 13 aufweist. Die zweite Platte 7 und die benachbarte Wärmetauscherplatte 4 sind nahezu vollständig umlaufend linienförmig miteinander verlötet, wobei ein Durchbruch 14 im bereich der Verlötung einen Ein-/Auslass für Kühlfluid oder zu kühlendes Fluid darstellt. Ein Rand 8 der beiden die Grundplatte 3 bildenden Platten 6,7 ist offen ausgebildet, um ein Entweichen von Luft beim Verlöten zu ermöglichen. Als Material für die einzelnen Platten 6, 7 der Grundplatte 3 kommt Leichtmetall, beispielsweise Aluminium, in Betracht.According to the Fig. 1 , An inventive plate heat exchanger 1, which may be formed, for example, as an oil cooler, a cover plate 2, a built base plate 3 and a plurality of interposed stacked heat exchanger plates 4, which via edges 5 (see. FIGS. 5 and 6 ) are circumferentially fluid-tight soldered together. The plate heat exchanger 1 is connected via the base plate 3 with another component, such as an internal combustion engine, connectable, wherein in the base plate 3 corresponding supply / disposal openings or lines can be arranged. According to the invention, the base plate 3 is designed as a built-up base plate 3 and consists of at least two interconnected plates 6 and 7 (cf. Fig. 2 ) built up. The two plates 6, 7 of the base plate 3 are soldered flat to each other, wherein the first plate 6 is formed flat and the second plate has 7 elevations 13. The second plate 7 and the adjacent heat exchanger plate 4 are almost completely circumferentially soldered together with a line Breakthrough 14 in the field of soldering represents an inlet / outlet for cooling fluid or fluid to be cooled. An edge 8 of the two plates forming the base plate 3 is designed to be open in order to allow air to escape during soldering. As a material for the individual plates 6, 7 of the base plate 3 is light metal, such as aluminum, into consideration.

Die erfindungsgemäße Grundplatte 3 bietet den großen Vorteil, dass diese nicht mehr massiv, sondern vergleichsweise leicht und dadurch gewichtsoptimiert aufgebaut ist, was beim Einsatz als Ölkühler in Kraftfahrzeugen neben der Gewichtsersparnis auch eine Reduzierung des Kraftstoffverbrauchs ermöglicht. Zusätzlich geht mit der erfindungsgemäßen, mehrlagigen Ausbildung der Grundplatte 3 auch eine Materialeinsparung einher, die insbesondere im Hinblick auf stetig steigende Rohstoffpreise von großem Vorteil ist. Durch die Erhebungen 13 weist die Grundplatte 3 und damit auch der Wärmetauscher 1 zudem eine gesteigerte Festigkeit/Steifigkeit auf.The base plate 3 according to the invention has the great advantage that it is no longer solid, but comparatively lightweight and thus weight-optimized, which, when used as an oil cooler in motor vehicles in addition to the weight savings also allows a reduction in fuel consumption. In addition, with the multilayered design of the base plate 3 according to the invention, a material saving is also accompanied, which is of great advantage, in particular with regard to steadily rising raw material prices. By the elevations 13, the base plate 3 and thus also the heat exchanger 1 also has an increased strength / rigidity.

Die erste Platte 6 der Grundplatte 3 kann dabei beispielsweise eine Dicke von ca. 0,5 mm aufweisen, wogegen die zweite Platte 7 der Grundplatte 3 eine Dicke von ca. 1,0 mm aufweist. Bisher aus dem Stand der Technik bekannte, massive Grundplatten besaßen beispielsweise eine Dicke von ca. 5 mm, so dass mit der erfindungsgemäßen Grundplatte eine Materialeinsparung sowie eine Gewichtseinsparung von über 50 % problemlos erreichbar sind.The first plate 6 of the base plate 3 may for example have a thickness of about 0.5 mm, whereas the second plate 7 of the base plate 3 has a thickness of about 1.0 mm. So far known from the prior art, massive base plates had, for example, a thickness of about 5 mm, so that with the base plate according to the invention a material saving and a weight saving of over 50% are easily achievable.

Betrachtet man die Fig. 2 und 3, so kann man erkennen, dass die beiden Platten 6, 7 der Grundplatte 3 flächig miteinander verlötet sind, wogegen eine Verlötung der zweiten Platte 7 mit der benachbarten Wärmetauscherplatte 4 linienförmig über entsprechende Lötnähte 9 bzw. punktförmig im Bereich von Turbulenzkonturen 10 erfolgt.Looking at the FIGS. 2 and 3 , it can be seen that the two plates 6, 7 of the base plate 3 are soldered flat to each other, whereas a soldering of the second plate 7 with the adjacent heat exchanger plate 4 linearly via corresponding solder joints 9 and punctiform in the range of turbulence contours 10 takes place.

Betrachtet man insbesondere die Fig. 1, 5 und 6, so kann man die Turbulenzkonturen 10 erkennen, die ein gleichmäßiges Durchströmen der Wärmetauscherplatten 4 mit Kühlmittel oder zu kühlendem Fluid, beispielsweise Öl, bewirken. Die einzelnen Turbulenzkonturen 10 benachbarter Wärmetauscherplatten 4 berühren sich dabei wiederum punktförmig und können über diese punktartigen Kontakte miteinander verbunden, insbesondere miteinander verlötet werden.Looking in particular at the Fig. 1 . 5 and 6 , so you can see the turbulence contours 10, which cause a uniform flow through the heat exchanger plates 4 with coolant or fluid to be cooled, such as oil. The individual turbulence contours 10 of adjacent heat exchanger plates 4 in turn touch punctiform and can be connected to one another via these point-like contacts, in particular soldered together.

Das Verfahren zur Herstellung des erfindungsgemäßen Plattenwärmetauschers 1 gestaltet sich dabei wie folgt:The method for producing the plate heat exchanger 1 according to the invention is designed as follows:

Zunächst werden die Grundplatte 3, die Wärmetauscherplatten 4 sowie die Deckplatte 2 an insbesondere separaten Produktions- bzw. Prägestationen gestanzt und geprägt, das heißt hergestellt. Anschließend werden die derart hergestellten Elemente, das heißt die Deckplatte 2, die Grundplatte 3 und die Wärmetauscherplatten 4 in einer Fixiervorrichtung 11 (vgl. Fig. 4) solllagengemäß gestapelt, wobei Vertikalführungen 12 an der Fixiervorrichtung 11 die Solllage garantieren. Der derart hergestellte Werkstückstapel, das heißt der vorgestapelte Plattenwärmetauscher 1 wird zusammen mit der Fixiervorrichtung 11 in einen Lötofen eingebracht, wobei die Grundplatte 3, die Wärmetauscherplatten 4 und die Deckplatte 2 gemeinsam miteinander verlötet werden.First, the base plate 3, the heat exchanger plates 4 and the cover plate 2 are punched and embossed on, in particular, separate production or embossing stations, that is manufactured. Subsequently, the elements thus produced, that is, the cover plate 2, the base plate 3 and the heat exchanger plates 4 in a fixing device 11 (see. Fig. 4 ) should be stacked according to the situation, with vertical guides 12 on the fixing device 11 guarantee the desired position. The stack of workpieces produced in this way, that is to say the stacked plate heat exchanger 1, is introduced together with the fixing device 11 into a soldering furnace, wherein the base plate 3, the heat exchanger plates 4 and the cover plate 2 are soldered together.

Abschließend wird die Fixiervorrichtung 11 zusammen mit dem nunmehr verlöteten Plattenwärmetauscher 1 aus dem Lötofen entnommen und ist nun fertig zur Montage. Neben der Grundplatte 3 können selbstverständlich auch die Wärmetauscherplatten 4 und/oder die Deckplatte 2 aus einem Leichtmetall, insbesondere aus Aluminium ausgebildet sein.Finally, the fixing device 11 is removed together with the now soldered plate heat exchanger 1 from the soldering oven and is now ready for installation. In addition to the base plate 3, of course, the heat exchanger plates 4 and / or the cover plate 2 may be formed of a light metal, in particular of aluminum.

Der erfindungsgemäße Plattenwärmetauscher 1 besitzt dabei im Vergleich zu aus dem Stand der Technik bekannten Wärmetauschern eine leichte und zugleich steife Konstruktionsweise mit einer vergleichsweise hohen Kühlleistung.The plate heat exchanger 1 according to the invention has in comparison to known from the prior art heat exchangers a light and at the same time rigid construction with a comparatively high cooling capacity.
