Die vorliegende Erfindung beschäftigt sich mit dem Problem, für einen gattungsgemäßen Plattenwärmetauscher eine verbesserte oder zumindest eine alternative Ausführungsform anzugeben, die sich insbesondere durch hohe Qualität und eine vereinfachte und damit kostengünstige Herstellbarkeit auszeichnet.The present invention is concerned with the problem of providing for a generic plate heat exchanger, an improved or at least one alternative embodiment, which is characterized in particular by high quality and a simplified and thus cost manufacturability.

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 aus dem Stand der Technik bekannten Plattenwärmetauscher mit einer Deckplatte, einer Grundplatte und dazwischen stapelartig angeordneten Wärmetauscherplatten, die Grundplatte aus einem kostengünstigen Blechformteil auszubilden und nicht wie bisher aus dem Stand der Technik bekannt, aus einer bis zu 5 mm dicken Metallplatte. Die erfindungsgemäße Grundplatte überragt dabei die darauf angeordneten, benachbarten Wärmetauscherplatten randseitig und weist zudem einen in Richtung des Wärmetauscherplattenstapels aufgestellten Rand auf, der zumindest abschnittsweise einem Umriss des Wärmetauscherplattenstapels folgt und dadurch diesen hinsichtlich seiner Lage auf der Grundplatte fixiert. Erfindungsgemäß ist nun dieser Rand zumindest teilweise durch einen einstückig mit der Grundplatte ausgebildeten und entlang von Falzlinien umgebogenen Abschnitt gebildet. Im Klartext heißt dies, dass die Grundplatte zunächst als ebenes Blechteil ausgestanzt wird, wobei dann in darauf folgenden Biegeschritten entsprechende (Blech-)Fortsätze entlang von vordefinierten Falzlinien umgebogen und dadurch der aufgestellte Rand gebildet wird. Durch die umgebogenen Fortsätze entstehen insbesondere in den jeweiligen Randbereichen Doppellagen, wodurch die Steifigkeit der Grundplatte an sich erhöht wird. Da diese Doppellagen jedoch nur partiell vorgesehen sind, weist die erfindungsgemäß hergestellte Grundplatte insgesamt ein deutlich geringeres Gewicht auf als bisher aus dem Stand der Technik bekannte und aus einer Metallplatte hergestellte Grundplatten. Das Herstellen der erfindungsgemäßen Grundplatte ist aufgrund ihrer konstruktiven Besonderheit besonders einfach und zugleich kostengünstig. Selbstverständlich können darüber hinaus zusätzlich benötigte Durchgangsöffnungen der Grundplatte gleichzeitig mit dem Ausstanzen derselben aus bspw. einem Blechbogen mit ausgestanzt werden. Erfindungsgemäß besteht die Grundplatte im Wesentlichen aus einem Blechzuschnitt, der an randparallelen Falzlinien einstückig anschließende (Blech-)fortsätze aufweist, die unter Bildung gedoppelter (Blech-)bereiche in Richtung der Wärmetauscherplatten umgeschlagen und deren falzlinienferne Ränder relativ zur Ebene des Blechzuschnittes aufgebogen und an einen benachbarten Rand der Wärmetauscherplatten angeschmiegt sind.The present invention is based on the general idea, in a known from the prior art plate heat exchanger with a cover plate, a base plate and interposed stacked heat exchanger plates to form the base plate from a cost sheet metal part and not known from the prior art, as is known from a metal plate up to 5 mm thick. The base plate according to the invention projects beyond the adjacent heat exchanger plates arranged on the edge and also has an erected in the direction of the heat exchanger plate stack edge, which at least partially follows an outline of the heat exchanger plate stack and thereby fixes this with respect to its position on the base plate. According to the invention, this edge is now at least partially formed by an integrally formed with the base plate and bent along fold lines section. In plain language, this means that the base plate is first punched out as a flat sheet metal part, which then in subsequent bending advances corresponding (sheet) extensions along bent predefined fold lines and thereby the erected edge is formed. The bent projections create double layers, in particular in the respective edge regions, as a result of which the rigidity of the base plate is increased. However, since these double layers are provided only partially, the base plate according to the invention has a significantly lower overall weight than previously known from the prior art and made of a metal plate base plates. The manufacture of the base plate according to the invention is particularly simple and at the same time inexpensive due to their structural feature. Of course, additionally required through holes of the base plate can be used simultaneously with the punching of the same, for example. a sheet metal are punched out with. According to the invention, the base plate essentially consists of a sheet metal blank which integrally adjoins edge-parallel folding lines (sheet) extensions, which turned double-edged (sheet) areas in the direction of the heat exchanger plates and their falzlinienferne edges bent relative to the plane of the blank and cut to a adjacent edge of the heat exchanger plates are nestled.

Bei einer vorteilhaften Weiterbildung der erfindungsgemäßen Lösung ist die Grundplatte aus Blech oder aus Leichtmetall, insbesondere aus Aluminium, ausgebildet. Durch die Ausbildung aus Leichtmetall, insbesondere aus Aluminium, lässt sich ein weiterer Gewichtsvorteil erreichen, wobei bereits die aus normalen Blech erfindungsgemäß hergestellte Grundplatte im Vergleich zu aus dem Stand der Technik bekannten und aus einer dicken Metallplatte geformten Grundplatte deutlich weniger Material und damit auch deutlich weniger Gewicht aufweist. Neben der Gewichtsoptimierung bietet auch die Materialeinsparung im Hinblick auf die sich stetig verteuernden Rohstoffe einen nicht zu unterschätzenden Vorteil. Generell kann die erfindungsgemäße Grundplatte mittels herkömmlich bekannter Stanz- und Umformmaschinen schnell, qualitativ hochwertig und zugleich kostengünstig hergestellt werden. Die umgebogenen Randbereiche, d. h. die umgebogenen Blechfortsätze, fixieren dabei nicht nur den Wärmetauscherplattenstapel hinsichtlich seiner Lage in Bezug auf die Grundplatte, sondern versteifen die Grundplatte zusätzlich, da insbesondere die Falzlinien und die in diesem Bereich gedoppelten Blechabschnitte hohe Steifigkeiten ermöglichen.In an advantageous development of the solution according to the invention, the base plate made of sheet metal or light metal, in particular aluminum, formed. The design of light metal, especially aluminum, another weight advantage can be achieved, which already made of normal sheet metal according to the invention base plate compared to known from the prior art and formed from a thick metal plate base plate significantly less material and thus significantly less Has weight. In addition to weight optimization, the material savings with regard to the constantly increasing raw materials also offers an advantage that should not be underestimated. In general, the base plate according to the invention can be produced by means of conventionally known punching and forming machines quickly, with high quality and at the same time inexpensively. The bent edge areas, d. H. The bent sheet metal extensions, not only fix the heat exchanger plate stack in terms of its position with respect to the base plate, but also stiffen the base plate, in particular because the fold lines and doubled in this area sheet metal sections allow high stiffness.

Bei einer weiteren vorteilhaften Ausführungsform der erfindungsgemäßen Lösung fasst der aufgestellte und aus den umgebogenen Blechfortsätzen hergestellte Rand Eckbereiche der Wärmetauscherplatten nicht ein. Der derart hergestellte Rand liegt somit nur an Längs- bzw. Querrändern des Wärmetauscherplattenstapels an, wogegen jedoch die Eckbereiche frei bleiben. Selbstverständlich können dabei die Ränder an der Längs- bzw. Querseite des Wärmetauscherplattenstapels eine zur Länge bzw. Breite der jeweiligen Wärmetauscherplatte nahezu identische Länge aufweisen, sodass der tatsächlich nicht eingefasste Eckbereich vergleichsweise gering ausfällt.In a further advantageous embodiment of the solution according to the invention, the erected edge produced from the bent sheet-metal projections does not encompass corner regions of the heat exchanger plates. The edge thus produced is thus only on longitudinal or transverse edges of the heat exchanger plate stack, whereas, however, the corner areas remain free. Of course you can in this case, the edges on the longitudinal or transverse side of the heat exchanger plate stack have a length that is virtually identical to the length or width of the respective heat exchanger plate, so that the corner area that is actually not enclosed turns out to be comparatively small.

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.

Über die Grundplatte 3 wird der Plattenwärmetauscher 1 bspw. an einem Verbrennungsmotor befestigt. Um nun die Grundplatte 3 einerseits kostengünstig und andererseits konstruktiv einfach und zudem gewichtsoptimiert ausbilden zu können, ist bei der erfindungsgemäßen Grundplatte 3 gemäß den Fig. 2 bis 6 der Rand 5 zumindest bereichsweise durch einen einstückig mit der Grundplatte 3 ausgebildeten und durch entlang von Falzlinien 6a bis 6d umgebogenen Fortsatz 7, insbesondere einen Blechfortsatz 7, gebildet.

About the base plate 3, the plate heat exchanger 1, for example, attached to an internal combustion engine. In order to form the base plate 3 on the one hand cost and on the other hand structurally simple and also weight-optimized, is in the inventive base plate 3 according to the Fig. 2 to 6 the edge 5 at least partially formed by an integrally formed with the base plate 3 and by along fold lines 6a to 6d bent extension 7, in particular a sheet metal extension 7. The base plate 3 may, for example, from sheet metal or light metal, in particular aluminum, be formed.

Die Grundplatte 3 ist darüber hinaus im Wesentlichen aus einem Blechzuschnitt ausgebildet, der an den randparallelen Falzlinien 6a bis 6d einstückig anschließende Blechfortsätze 7 besitzt, die unter Bildung gedoppelter Blechbereiche 8 in Richtung der Wärmetauscherplatten 4 umgeschlagen und deren falzlinienferne Ränder 9 relativ zur Ebene des Blechzuschnitts aufgebogen und an einen benachbarten Rand der Wärmetauscherplatten 4 angeschmiegt sind. Unter Blechzuschnitt kann ein Zuschnitt aus einem Bandmaterial verstanden werden.The base plate 3 is also formed essentially of a sheet metal blank, which has integrally adjacent sheet metal extensions 7 on the edge-parallel fold lines 6a to 6d, 8 folded over the formation of doubled sheet metal areas in the direction of the heat exchanger plates 4 and their falzlinienferne edges 9 bent relative to the plane of the sheet metal blank and are nestled against an adjacent edge of the heat exchanger plates 4. Under sheet metal blank can be understood a blank of a strip material.

Durch die erfindungsgemäße Ausbildung der Grundplatte 3 als Blechstanz-/Formteil lässt sich diese nicht nur kostengünstig und vergleichsweise einfach sondern zudem auch mit einer erhöhten Steifigkeit, bedingt durch die gedoppelten Blechbereiche 8, fertigen. Im Vergleich zu bisher aus dem Stand der Technik bekannten Grundplatten weist die erfindungsgemäße Grundplatte 3 jedoch ein deutlich geringeres Gewicht auf, da die Materialstärke sowie die eingesetzte Materialmenge deutlich reduziert werden können. Betrachtet man die Fig. 2, so kann man erkennen, dass die Grundplatte 3 einen Mittelbereich 10 aufweist, an dessen Längsseiten Fortsätze 7 angeordnet sind. Diese Fortsätze 7 sind jeweils nahe der Längsenden des Mittelbereichs 10 einstückig mit dem Mittelbereich 10 der Grundplatte 3 verbunden, wobei zwischen diesen Verbindungsbereichen, die im Wesentlichen den gedoppelten Bereichen 8 entsprechen, jeweils an der jeweiligen Falzlinie 6a und 6b entlang dieser Falzlinie 6a, 6b langgestreckte Aussparungen 11 vorgesehen sind.Due to the inventive design of the base plate 3 as Blechstanz- / molding this can not only cost and relatively simple but also with an increased rigidity, due to the doubled sheet metal areas 8 finished. Compared to previously known from the prior art base plates, however, the base plate 3 of the invention has a significantly lower weight, since the material thickness and the amount of material used can be significantly reduced. Looking at the Fig. 2 , it can be seen that the base plate 3 has a central region 10, on whose longitudinal sides projections 7 are arranged. These extensions 7 are each near the longitudinal ends of the central region 10 integral with the central region 10 of Base plate 3 is connected, wherein between these connecting portions, which substantially correspond to the doubled areas 8, respectively elongated recesses 11 are provided at the respective fold line 6a and 6b along this fold line 6a, 6b.

Demgegenüber sind die Fortsätze 7 bei der Grundplatte 3 gemäß der Fig. 3 nur in einem Mittelabschnitt der jeweiligen Falzlinie 6a bis 6d einstückig mit dem Mittelbereich 10 der Grundplatte 3 verbunden, wobei beidseitig dieses Verbindungsbereichs zur jeweiligen Falzlinie 6a bis 6d symmetrische Einschnitte 12 zwischen dem jeweiligen Fortsatz 7 und dem Mittelbereich 10 der Grundplatte 3 vorgesehen sind. Gemäß der Fig. 3 ist dabei der um die Falzlinie 6b umgebogene Fortsatz 7 zugleich in seiner nicht umgebogenen, d. h. zum Mittelbereich 10 fluchtenden Stellung mit unterbrochen gezeichneter Linie dargestellt. Die übrigen Fortsätze 7 werden in ähnlicher Weise durch einfaches Umbiegen um die jeweiligen Falzlinien sowie das nachträgliche Aufstellen des Randes 9 hergestellt.In contrast, the extensions 7 in the base plate 3 according to the Fig. 3 only in a central portion of the respective fold line 6a to 6d integrally connected to the central region 10 of the base plate 3, wherein on both sides of this connection region to the respective fold line 6a to 6d symmetrical cuts 12 between the respective extension 7 and the central region 10 of the base plate 3 are provided. According to the Fig. 3 In this case, the extension 7 bent over the fold line 6b is at the same time shown in its non-bent position, ie aligned with the central region 10, with an interrupted drawn line. The remaining extensions 7 are made in a similar manner by simply bending around the respective folding lines and the subsequent setting up of the edge 9.

Fig. 4 zeigt eine Grundplatte 3, die im Wesentlichen derjenigen der Fig. 3 entspricht, wobei die Fortsätze 7 an den kürzeren Querseiten entfallen. In diesem Fall sind nur an den zwei Längsseiten des Mittelbereichs 10 der Grundplatte 3 mit dem Mittelbereich 10 einstückig verbundene Fortsätze 7 vorgesehen, wobei gemäß der Ausgestaltung nach Fig. 5 an den Querseiten des Mittelbereichs 10 durch aufliegend angeordnete und aufgebogene Blechstücke gedoppelte Befestigungsbereiche mit entsprechenden Rändern 9 vorgesehen werden können. Diese werden dann mit der Grundplatte 3 verbunden, bspw. verlötet. Fig. 4 shows a base plate 3, which is substantially that of Fig. 3 corresponds, wherein the extensions 7 account for the shorter transverse sides. In this case, only on the two longitudinal sides of the central region 10 of the base plate 3 with the central region 10 integrally connected extensions 7 are provided, according to the embodiment according to Fig. 5 on the transverse sides of the central region 10 by means of lying arranged and raised sheet metal pieces doubled mounting areas with corresponding edges 9 can be provided. These are then connected to the base plate 3, for example. Soldered.

Die gemäß den Fig. 3 bis 5 gezeigten Grundplatten 3 weisen in Draufsicht die Form eines ellipsenartig langgestreckten Zwölfecks auf. Sämtlichen gemäß den Fig. 2 bis 5 gezeigten erfindungsgemäßen Ausführungsformen der Grundplatte 3 ist gemein, dass diese Eckbereiche des Wärmetauscherplattenstapels mit den Rändern 9 nicht einfassen.The according to the Fig. 3 to 5 shown base plates 3 have in plan view the shape of an ellipse-like elongated dodecagon. All according to the Fig. 2 to 5 shown embodiments of the base plate 3 is common that these corner regions of the heat exchanger plate stack do not border with the edges 9.
