Description
Die vorliegende Erfindung betrifft ein Plattenelement für einen Plattenkühler sowie einen Plattenkühler, umfassend eine Mehrzahl von baugleichen Plattenelementen.The present invention relates to a plate element for a plate cooler and to a plate cooler, comprising a plurality of plate elements of the same construction.
Aus dem Stand der Technik sind Plattenkühler bekannt, bei denen eine Anzahl von zumeist baugleichen, alternierend angeordneten Plattenelementen übereinander angeordnet sind, wobei zwei getrennte Systeme von Kammern gebildet werden, wobei ein erstes wärmeübertragendes Medium durch das eine Kammersystem und ein zweites Medium durch das andere Kammersystem strömt. Allgemein besteht dabei die Problematik, die Strömungswege der Medien innerhalb der Kammern zu optimieren, so dass bei gegebener Baugröße und Plattenanzahl ein möglichst optimaler Wärmetausch zwischen den beiden Medien gegeben ist.Plate coolers are known from the prior art in which a number of mostly structurally identical, alternating plate elements are arranged one above the other, two separate systems of chambers being formed, a first heat-transferring medium through one chamber system and a second medium through the other chamber system flows. In general, there is the problem of optimizing the flow paths of the media within the chambers, so that the best possible heat exchange between the two media is given for a given size and number of plates.
Es ist die Aufgabe der Erfindung, ein Plattenelement für einen Plattenkühler anzugeben, mittels dessen ein in seinem Wirkungsgrad und seine Ablagerungsresistenz verbesserter Plattenkühler herstellbar ist.It is the object of the invention to specify a plate element for a plate cooler, by means of which a plate cooler can be produced which is improved in terms of its efficiency and its resistance to deposits.
Diese Aufgabe wird für ein eingangs genanntes Plattenelement erfindungsgemäß mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved according to the invention for a plate element mentioned at the outset with the features of
Durch diese Formgebung, insbesondere durch die zwischen Seitenwandung und zweitem Öffnungsrand verlaufende Sockelfläche wird auf einfache Weise erreicht, dass ein besonders kleiner Anteil an wärmetragendem Medium in einem strömungsarmen Bereich eines Plattenkühlers vorhanden ist. Insbesondere hinsichtlich der Medienströmung ungünstige Bereiche zwischen Außenrand des Plattenkühlers und Medienöffnungen werden verkleinert oder eliminiert, so daß das Medium hauptsächlich zwischen denThrough this shape, in particular through the base surface running between the side wall and the second opening edge, it is achieved in a simple manner that a particularly small proportion of heat-carrying medium is present in a low-flow area of a plate cooler. Areas between the outer edge of the plate cooler and media openings that are unfavorable in particular with regard to the media flow are reduced in size or eliminated so that the medium mainly between the
Öffnungen und somit in seinen Hauptströmungsbereichen vorhanden ist. Insgesamt kann somit eine gleiche Tauscherleistung bei kleinerem im Plattenkühler vorhandenem Medienvolumen erzielt werden. Hierdurch kann ein Plattenkühler insgesamt leichter und kleinbauender ausgebildet werden.Openings and thus is present in its main flow areas. Overall, the same exchanger performance can be achieved with a smaller volume of media in the plate cooler. As a result, a plate cooler can be designed to be lighter and smaller overall.
Im Interesse einer einfachen Herstellung eines Plattenkühlers ist das Plattenelement mit einem zweiten, baugleichen Plattenelement verbindbar, wobei in der verbundenen Anordnung eine im Wesentlichen flächige Anlage der Sockelfläche des Plattenelements des zweiten Plattenelement vorliegt. Durch die baugleiche Ausführung des zweiten Plattenelements wird eine besonders wirtschaftliche Fertigung eines Plattenkühlers ermöglicht.In the interest of a simple production of a plate cooler, the plate element can be connected to a second, structurally identical plate element, with the base surface of the plate element of the second plate element being substantially flat in the connected arrangement. The structurally identical design of the second plate element enables particularly economical production of a plate cooler.
Weiterhin bevorzugt ist das Plattenelement dabei mit dem zweiten Plattenelement zumindest im Bereich der flächigen Anlage flächig verlötet. Im Gegensatz zu der aus dem Stand der Technik bekannten im Wesentlichen linienförmigen Verlötung, die durch die im Prinzip eindimensionale Ausbildung der Ränder gegeben ist, kann somit bei einem erfindungsgemäßen Plattenelement eine wesentlich größere Kontaktfläche benachbarter Plattenelemente eines Plattenkühlers verlötet sein, so dass insgesamt eine besonders große Festigkeit und eine besonders große Langzeitstabilität gegenüber Rissen und auftretenden Leckagen gegeben ist.Furthermore, the plate element is preferably soldered flat to the second plate element at least in the area of the flat contact. In contrast to the essentially line-shaped soldering known from the prior art, which is provided by the basically one-dimensional design of the edges, a significantly larger contact surface of adjacent plate elements of a plate cooler can thus be soldered in a plate element according to the invention, so that overall a particularly large Strength and a particularly high long-term stability against cracks and leaks that occur is given.
Bei einem erfindungsgemäßen Plattenelement weisen die Öffnungen eine sich in einer Längsrichtung erstreckende, von einer Kreisform abweichende Form auf.

A secure connection of plate elements with the shape of the openings deviating from a circular shape is given in particular in the case of the aforementioned flat contact or flat soldering.
Ein erfindungsgemäßes Plattenelement weist eine Profilierung auf, wobei die Profilierung in einem Strömungsweg zur Beeinflussung der Strömung des Mediums angeordnet ist. Durch eine solche Profilierung kann die Verteilung des Mediumstromes über das Plattenelement zum Zwecke der Optimierung der Tauscherleistung verbessert werden. Im Interesse einer einfachen Herstellung ist die Profilierung bevorzugt durch Prägung bzw. Verformung des Bodens des Plattenelements ausgebildet.A plate element according to the invention has a profile, the profile being arranged in a flow path for influencing the flow of the medium. Such a profiling can improve the distribution of the medium flow over the plate element for the purpose of optimizing the exchanger performance. In the interests of simple production, the profiling is preferably formed by embossing or deforming the bottom of the plate element.
Dabei ist die Profilierung wellenförmig, wobei zwischen der Profilierung des Plattenelements und der Profilierung eines baugleichen zweiten Plattenelements, welches an dem ersten Plattenelement festgelegt ist, eine Mehrzahl von Berührungsstellen der Profilierungen vorliegen. Hierdurch läßt sich eine besonders gezielte Führung des Mediumstromes durch die Profilierung erreichen.The profiling is wave-shaped, with a plurality of contact points of the profiling being present between the profiling of the plate element and the profiling of a structurally identical second plate element which is fixed to the first plate element. In this way, a particularly targeted guidance of the medium flow through the profiling can be achieved.
Im Interesse einer einfachen Herstellung ist das Plattenelement insgesamt aus einer Metallplatte konstanter Dicke herstellbar. Die Formung des Plattenelements aus der Metallplatte konstanter Dicke kann dabei mittels an sich bekannter Verfahren erfolgen, etwa mittels Tiefziehen, Gesenkschmieden oder anderen Methoden. Das Material der Metallplatte ist bevorzugt eine Aluminiumlegierung, um insgesamt eine leichte Bauweise eines Plattenkühlers zu ermöglichen.In the interests of simple production, the plate element can be produced entirely from a metal plate of constant thickness. The plate element can be formed from the metal plate of constant thickness by means of methods known per se, for example by means of deep drawing, die forging or other methods. The material of the metal plate is preferably an aluminum alloy in order to enable a plate cooler to be constructed in a lightweight manner overall.
