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 a plate cooler, comprising a plurality of identical plate elements.

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 identical, alternately arranged plate elements are arranged one above the other, wherein two separate systems are formed by chambers, wherein a first heat-transmitting medium through the 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 given the size and number of plates optimum heat exchange between the two media is given.

DE 199 39 264 A1 beschreibt einen Plattenwärmerübertrager in Stapelbauweise, bei dem eine Mehrzahl identischer Plattenelemente aufeinander festgelegt und entlang eines konischen Außenrandes miteinander verlötet sind. Die Plattenelemente weisen jeweils vier im Wesentlichen kreisrunde Öffnungen innerhalb eines Bodenbereiches des Plattenelementes auf, wobei zwei der kreisrunden Öffnungen jeweils einen abgekragten Rand haben. Jeder der abgekragten Ränder ist zu dem Außenrand beabstandet angeordnet. Bei Stapelung der Plattenelemente ergibt sich in den Bereichen zwischen dem Außenrand und den Abkragungen der Öffnungen ein erhebliches Volumen, in dem sich ein wärmeführendes Medium mit besonders geringer Strömungsgeschwindigkeit befindet. Zum einen wird hierdurch der Wirkungsgrad des Wärmetauschers bei gegebenen Abmessungen ungünstig beeinflußt. Zum anderen ermöglichen solche Bereiche von annähernd stehendem Medium die Ablagerung von mitgeführten Partikeln und die Agglomeration zu großvolumigen Ablagerungen. Ein spontanes Lösen solcher größerer Ablagerungen kann sich schädlich auf ein Gesamtsystem auswirken, beispielsweise wenn der Wärmetauscher ein Ölkühler eines Kraftfahrzeugmotors ist. DE 199 39 264 A1 describes a plate heat exchanger in a stacked construction, in which a plurality of identical plate elements are fixed to each other and soldered together along a conical outer edge. The plate elements each have four in the Substantially circular openings within a bottom portion of the plate member, wherein two of the circular openings each have a bevelled edge. Each of the bevelled edges is spaced from the outer edge. When stacking the plate elements results in the areas between the outer edge and the Abkragungen the openings a considerable volume in which a heat-conducting medium is particularly low flow velocity. On the one hand, the efficiency of the heat exchanger is adversely affected given given dimensions unfavorable. On the other hand, such areas of approximately stationary medium allow the entrainment of entrained particles and the agglomeration to large-volume deposits. A spontaneous release of such larger deposits can be detrimental to an overall system, for example, when the heat exchanger is an oil cooler of a motor vehicle engine.

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 provide a plate element for a plate cooler, by means of which an improved in its efficiency and its deposition resistance plate cooler can be produced.

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 an initially mentioned plate element with the features of claim 1.

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 denBy this shaping, in particular by the base surface extending 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 region of a plate cooler. In particular with regard to the media flow unfavorable areas between the outer edge of the plate cooler and media openings are reduced 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, it is thus possible to achieve the same exchanger performance with a smaller volume of media in the plate cooler. As a result, a plate cooler overall can be made lighter and kleinbauender.

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 is connectable to a second, identical plate element, wherein in the connected arrangement there is a substantially planar contact of the base surface of the plate element of the second plate element. Due to the identical design of the second plate member a particularly economical production of a plate cooler is made possible.

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.Further preferably, the plate element is soldered to the second plate element, at least in the area of the planar contact surface. In contrast to the known from the prior art substantially line-shaped soldering, which is given by the in principle one-dimensional design of the edges, can thus be soldered in a plate element according to the invention a much larger contact area of adjacent plate elements of a plate cooler, so that a total of a particularly large Strength and a particularly high long-term stability against cracks and leaks occurring is given.

In bevorzugter Ausführung eines erfindungsgemäßen Plattenelements weist zumindest eine der Öffnungen eine sich in einer Längsrichtung erstreckende, von einer Kreisform abweichende Form auf. Hier ist auf einfache Weise ermöglicht, dass das Medium in einem besonders breiten Bereich einen aus erfindungsgemäßen Plattenelementen bestehenden Plattenkühler durchströmt. Eine sichere Verbindung von Plattenelementen mit von einer Kreisform abweichender Form der Öffnungen ist insbesondere bei der vorgenannten flächigen Anlage beziehungsweise flächigen Verlötung gegeben.In a preferred embodiment of a plate element according to the invention, at least one of the openings has a shape extending in a longitudinal direction and deviating from a circular shape. Here, it is made possible in a simple manner that the medium flows through a plate cooler consisting of plate elements according to the invention in a particularly wide area. A secure connection of plate elements with a shape deviating from a circular shape of the openings is particularly in the given above surface conditioning or surface 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.An inventive plate element has a profiling, wherein the profiling is arranged in a flow path for influencing the flow of the medium. By such a profiling, the distribution of the medium flow over the plate member for the purpose of optimizing the heat exchange performance can be improved. In the interests of ease of manufacture, the profiling is preferably formed by embossing or deformation of 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.In this case, the profiling is undulating, wherein there are a plurality of contact points of the profilings between the profiling of the plate member and the profiling of a structurally identical second plate member, which is fixed to the first plate member. As a result, a particularly targeted guidance of the medium flow can be achieved by the profiling.

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 interest of ease of manufacture, the plate element as a whole of a metal plate of constant thickness produced. The shaping of the plate member from the metal plate of constant thickness can be done by means of known methods, such as by deep drawing, drop forging or other methods. The material of the metal plate is preferably an aluminum alloy to allow a total of a lightweight construction of a plate cooler.

Ein erfindungsgemäßer Plattenkühler umfasst eine Mehrzahl von baugleichen Plattenelementen nach Anspruch 1. Hierdurch werden die Vorteile der Formgebung des erfindungsgemäßen Plattenelements mit einer kostengünstigen Serienfertigung eines Plattenkühlers kombiniert.A plate cooler according to the invention comprises a plurality of identical plate elements according to claim 1. This provides the advantages of the shaping of the invention Plate element combined with a cost-effective mass production of a plate cooler.

Weitere Vorteile und Merkmale ergeben sich aus dem nachfolgend beschriebenen Ausführungsbeispiel sowie aus den abhängigen Ansprüchen.Further advantages and features will become apparent from the embodiment described below and from the dependent claims.

Das Plattenelement gemäß Fig. 1 umfasst eine Bodenebene 1 mit zwei sich in Strömungsrichtung eines Medium gegenüberliegenden Öffnungen 2, 3 eines ersten Typs, welche beide einen in der Bodenebene 1 liegenden Rand 2a, 3a aufweisen. Die beiden ersten Öffnungen 2, 3 sind jeweils länglich ausgebildet, wobei ein Längsdurchmesser der Öffnungen 2, 3 etwas mehr als das 1,5-fache eines Querdurchmessers ausmacht. Die Strömung des Mediums erfolgt senkrecht zu der Längsrichtung der Öffnungen 2, 3. Das Plattenelement 1 weist in der Draufsicht eine rechteckige Form mit stark verrundeten Ecken auf. Die beiden ersten Öffnungen 2, 3 sind beide an der gleichen Längsseite in den Eckbereichen des Rechtecks angeordnet.The plate element according to Fig. 1 comprises a bottom plane 1 with two facing in the flow direction of a medium openings 2, 3 of a first type, both of which have a lying in the ground plane 1 edge 2a, 3a. The two first openings 2, 3 are each elongate, with a longitudinal diameter of the openings 2, 3 a little more than 1.5 times a transverse diameter. The flow of the medium is perpendicular to the longitudinal direction of the openings 2, 3. The plate member 1 has in plan view a rectangular shape with strongly rounded corners. The two first openings 2, 3 are both arranged on the same longitudinal side in the corner regions of the rectangle.

An der gegenüberliegenden Längsseite sind zwei Öffnungen 4, 5 eines zweiten Typs vorgesehen, welche in Form und Öffnungsweite den ersten Öffnungen 2,3 gleichen. Die Ränder 4a, 5a der zweiten Öffnungen 4, 5 sind jedoch nicht in Höhe der Bodenebene 1 angeordnet, sondern liegen in einer zu der Bodenebene 1 parallelen Ebene. Ebenso in dieser Ebene liegen den Öffnungen 4,5 jeweils zugeordnete Sockelflächen 6, 7, des Plattenelements, welche zu der Bodenebene 1 parallel, aber in Richtung der Hochachse des Plattenelements versetzt angeordnet sind. Die Hochachse ist als in Fig. 6 senkrecht zur Zeichenebene definiert. Die Öffnungen 4,5 sind vorliegend als einfache Durchbrechungen der Sockelflächen 6, 7 ausgeformt. Sie können jedoch auch eine Abkragung aufweisen oder andere Abweichungen von einem einfachen Ausschnitt in der Sockelfläche.On the opposite longitudinal side two openings 4, 5 of a second type are provided, which are similar in shape and opening width of the first openings 2.3. However, the edges 4a, 5a of the second openings 4, 5 are not arranged at the level of the ground plane 1, but lie in a plane parallel to the ground plane 1 level. Also in this plane are the openings 4.5 each associated base surfaces 6, 7, of the plate member, which are arranged offset parallel to the ground plane 1, but in the direction of the vertical axis of the plate member. The vertical axis is as in Fig. 6 defined perpendicular to the drawing plane. The openings 4.5 are present as simple openings of the base surfaces 6, 7 formed. However, they can also have an overhang or other deviations from a simple cutout in the base surface.

Die Sockelflächen 6, 7 sind teilweise von einem jeweiligen verrundeten Rand 6a, 7a der Bodenebene 1 begrenzt und auf Höhe der Sockelflächen 6, 7 teilweise von einem verrundeten Ansatz 8b einer das Plattenelement umlaufenden Seitenwandung 8. Die Seitenwandung 8 umläuft das Plattenelement vollständig und weist einen vollständig in der gleichen Ebene liegenden Außenrand 8a auf. Diese Seitenwandung 8 ist zudem nicht rechtwinklig zu der Bodenebene 1 angeordnet, sondern leicht nach außen geneigt, weswegen sie insgesamt eine konische Anordnung hat. Hierdurch werden mehrerer baugleiche Plattenelemente ineinander stapelbar, wobei der Außenrand 8a jeweils auf einer gewissen Höhe der Seitenwandung 8 des nächsten Plattenelements anliegt und an dieser Stelle mit diesem verlötet ist (siehe Fig. 4).The base surfaces 6, 7 are partially bounded by a respective rounded edge 6a, 7a of the bottom plane 1 and at the level of the base surfaces 6, 7 partially of a rounded shoulder 8b of a side wall surrounding the plate element 8. The side wall 8 completely surrounds the plate element and has a completely in the same plane lying outer edge 8a. This side wall 8 is also not arranged at right angles to the bottom plane 1, but slightly inclined outwards, which is why it has a conical overall arrangement. As a result, a plurality of identical plate elements are stackable, wherein the outer edge 8a in each case bears against a certain height of the side wall 8 of the next plate member and is soldered at this point with this (see Fig. 4 ).

Die Sockelflächen 6, 7 erstrecken sich jeweils von dem Ansatz 8b der Seitenwandung 8 bis zu dem Rand 4a, 5a der zweiten Öffnungen 4, 5. Der Ansatzes 8b liegt im Bereich der Sockelflächen 6, 7 nicht auf gleicher Höhe wie im Bereich des Bodens 1, weshalb Stufen 8c im Verlauf des Ansatzes 8c vorkommen. Wie die gestapelte Darstellung gemäß Fig. 4 verdeutlicht, ergibt die flächige Anlage einer Sockelfläche 6, 7 an dem Boden 1 des nachfolgenden, um 180° verdreht angeordneten Plattenelements eine flächige Verlötung, die besonders stabil und sicher gegenüber während der Betriebsdauer auftretender Leckagen ist.The base surfaces 6, 7 each extend from the projection 8b of the side wall 8 to the edge 4a, 5a of the second openings 4, 5. The projection 8b is not in the region of the base surfaces 6, 7 at the same height as in the region of the bottom first why stages 8c occur during the course of the approach 8c. As the stacked representation according to Fig. 4 illustrates the surface contact of a base surface 6, 7 at the bottom 1 of the subsequent, rotated by 180 ° plate member results in a surface soldering, which is particularly stable and safe against leakage occurring during the operating period.

Wie Fig. 4 verdeutlicht, ist durch die alternierende Anordnung und dichtende Verlötung mehrerer Plattenelemente ein Teil eines Plattenkühlers ausgebildet, der ein erstes System A und ein zweites System B von Kammern umfasst. Dabei durchfließt ein erstes wärmetragendes Medium, beispielsweise Wasser und/oder Glykol, das erste System A jeweils von einer Plattenöffnung zur anderen senkrecht zur Zeichnungsebene in Fig. 4, und ein zweites wärmetragendes Medium, beispielsweise Motoröl, durchfließt das zweite System B jeweils von einer Plattenöffnung zur anderen senkrecht zur Zeichnungsebene in Fig. 4.As Fig. 4 illustrates, is formed by the alternating arrangement and sealing soldering a plurality of plate members, a part of a plate cooler comprising a first system A and a second system B of chambers. In this case, a first heat-carrying medium, for example water and / or glycol, flows through the first system A in each case from one plate opening to the other perpendicular to the plane of the drawing Fig. 4 and a second heat-carrying medium, for example engine oil, flows through the second system B from one plate opening to the other perpendicular to the plane of the drawing Fig. 4 ,

Die Herstellung des erfindungsgemäßen Plattenelements kann durch ein herkömmliches Umformverfahren erfolgen, wobei ein Rohling eine einfache Platte konstanter Dicke aus einer Aluminiumlegierung ist.The production of the plate element according to the invention can be carried out by a conventional forming process, wherein a blank is a simple plate of constant thickness of an aluminum alloy.

Das bevorzugte Plattenelement gemäß Fig. 1 bis Fig. 5 weist zudem eine Profilierung 9 der Bodenebene 1 auf. Diese Profilierung umfasst im Wesentlichen eine Mehrzahl von Zickzack- oder wellenförmigen Vertiefungen, die jeweils einen durchgehenden Kanal darstellen und von unten in den Boden 1 des Plattenelements eingeprägt sind. Jeder der zickzackförmigen Kanäle 9 quert einen gedachten Strömungsweg des Mediums, welcher jeweils von einer kurzen Seite des Plattenelements zur gegenüberliegenden kurzen Seite des Plattenelements verläuft. Die Kanäle 9 sind zudem so positioniert, dass sich bei Stapelung baugleicher Plattenelemente eine möglichst große Zahl von Überkreuzungen von Kanälen 9 des einen Plattenelements mit Kanälen 9 des anderen Plattenelements ergibt. An diesen Kreuzungsstellen liegen jeweils Berührungspunkte der benachbarten Kanäle 9 vor, was durch eine entsprechende Dimensionierung ihrer Prägetiefe sichergestellt ist. Bevorzugt sind die Platten an den Berührungspunkten miteinander verlötet.The preferred plate element according to Fig. 1 to Fig. 5 also has a profiling 9 of the ground level 1. This profiling essentially comprises a plurality of zigzag or wave-shaped depressions, which each represent a continuous channel and are embossed from below into the bottom 1 of the plate element. Each of the zigzag channels 9 crosses an imaginary flow path of the Medium, each of which extends from a short side of the plate member to the opposite short side of the plate member. The channels 9 are also positioned so that when stacking identical plate elements results in the largest possible number of crossings of channels 9 of a plate member with channels 9 of the other plate member. At these intersections, there are points of contact of the adjacent channels 9, which is ensured by a corresponding dimensioning of their embossing depth. Preferably, the plates are soldered together at the points of contact.

Insgesamt wird hierdurch eine gezielte Umlenkung und Verwirbelung des durchströmenden Mediums erreicht, was zu einer optimalen Kapazität des Wärmetauschers beiträgt.Overall, a targeted deflection and turbulence of the medium flowing through this is achieved, which contributes to an optimal capacity of the heat exchanger.

In einer Abwandlung gemäß Fig. 6 ist ein nicht erfindungsgemäßes Plattenelement bis auf die Profilierungen 9 identisch mit dem Ausführungsbeispiel gemäß Fig. 1 bis Fig. 5 ausgebildet, wobei anstelle der Profilierungen 9 eine in Fig. 6 schraffierte Turbulenzeinlage 10 an dem Plattenelement vorgesehen. ist. Derartige Turbulenzeinlagen 10 zur Verbesserung der thermischen Tauscherleistung sind an sich aus dem Stand der Technik bekannt.In a modification according to Fig. 6 is a non-inventive plate element except for the profiles 9 identical to the embodiment according to Fig. 1 to Fig. 5 formed, wherein instead of the profilings 9 a in Fig. 6 hatched turbulence insert 10 provided on the plate member. is. Such turbulence inserts 10 for improving the thermal exchange performance are known per se from the prior art.

Sämtliche der Zeichnungen sind maßstabsgerecht, so dass ihnen gegebenenfalls Maßverhältnisse entnommen werden können.All of the drawings are true to scale so that they can be taken from them if necessary.
