Abstract
Description
Die Erfindung bezieht sich auf einen Plattenwärmetauscher, insbesondere Ölkühler, aus mehreren ineinandergesteckten, je aus einer Wärmetauscherplatte mit umlaufendem Randsteg gebildeten Strömungswannen, die abwechselnd miteinander über Durchtrittsöffnungen für die wärmeaustauschenden Medien verbunden sind.The invention relates to a plate heat exchanger, in particular Oil cooler, consisting of several nested, each from a heat exchanger plate flow troughs formed with peripheral edge web, which alternate with each other via openings for the heat-exchanging media are connected.
Bekannte Plattenwärmetauscher dieser Art (US 4 708 199 A) haben den Vorteil eines einfachen Aufbaus, weil sich zwischen den als Wärmetauscherplatten wirksamen Böden der ineinandergesteckten und flüssigkeitsdicht miteinander verbundenen Strömungswannen abwechselnd Strömungskanäle für die beiden wärmeaustauschenden Medien, beispielsweise Öl und Wasser, ergeben. Die wärmeaustauschenden Medien werden dabei aus der einen Strömungswanne durch die unmittelbar anschließende hindurch in die jeweils übernächste Strömungswanne geleitet, und zwar über tiefgezogene Ansätze der Wannenböden. Die beiden Medien können somit aus einer ihrer Strömungswannen jeweils durch den tiefgezogenen Ansatz der anschließenden Strömungswanne für das jeweils andere Medium in die übernächste Strömungswanne strömen. Mit Hilfe von in die einzelnen Strömungswannen eingelegten Turbulenzblechen kann für eine entsprechende Strömungsaufteilung innerhalb der Strömungswannen gesorgt werden. Known plate heat exchangers of this type (US 4 708 199 A) have the advantage of a simple structure, because between the heat exchanger plates effective floors of the nested and liquid-tight with each other connected flow troughs alternating flow channels for the two heat-exchanging media, such as oil and water. The heat-exchanging media become one flow trough through the immediately following into the next but one flow trough passed, and that over deep-drawn approaches of the tub floors. The two media can thus each from one of their flow troughs through the deep-drawn approach of the subsequent flow trough for the each flow different medium into the next but one flow trough. With help of turbulence plates inserted in the individual flow troughs can be used for a corresponding flow distribution within the flow troughs be taken care of.
Um ein Vermischen der wärmeaustauschenden Medien zu verhindern, muß ein mediendichter Strömungsdurchtritt durch die Strömungswannen für das jeweils andere Medium erreicht werden, was eine entsprechend dichte Verbindung der tiefgezogenen Ansätze der Wannenböden mit den anschließenden Strömungswannen verlangt. Da für beide wärmeaustauschenden Medien Durchtritte durch die Strömungswannen für das jeweils andere Medium vorgesehen werden müssen, und zwar sowohl für die Zu- als auch für die Ableitung, ergibt sich eine Vielzahl von mediendicht auszuführenden Verbindungen, was die Gefahr einer Undichtheit und damit einer Medienvermengung erhöht. Außerdem wird durch die Vielzahl der tiefgezogenen Ansätze in den Wannenböden die wirksame Wärmeaustauschfläche der Wärmetauscherplatten verringert. Schließlich bedingen die zu den Strömungswannen senkrechten Zu- und Ableitungen der wärmeaustauschenden Medien nicht nur einen größeren Strömungswiderstand wegen der im Bereich jeder Wanne erforderlichen Strömungsumlenkungen, sondern beschränken auch die von der Lage der Zu- und Ableitungen der wärmeaustauschenden Medien abhängigen Einbaumöglichkeiten insbesondere für im Kraftfahrzeugbau eingesetzte Ölkühler.To prevent mixing of the heat exchanging media, a must media-tight flow passage through the flow troughs for each other medium can be achieved, which is a correspondingly tight connection of the deep-drawn approaches of the trough bottoms with the subsequent flow troughs demands. As penetrations for both heat exchanging media the flow troughs are provided for the other medium must, both for the supply as well as for the derivation, one results Variety of media-tight connections, which creates the risk of Leakage and thus media mixing increases. In addition, through the variety of deep-drawn approaches in the tub bottoms the effective Heat exchange area of the heat exchanger plates reduced. Finally condition the inlets and outlets of the heat-exchanging that are perpendicular to the flow troughs Media not only because of greater flow resistance the flow deflections required in the area of each tub, but also limit the location of the inlets and outlets of the heat exchangers Media-dependent installation options, especially for in motor vehicle construction used oil cooler.
Der Erfindung liegt somit die Aufgabe zugrunde, einen Plattenwärmetauscher der eingangs geschilderten Art mit einfachen konstruktiven Mitteln so auszubilden, daß die Gefahr einer Medienvermengung herabgesetzt, der Wirkungsgrad verbessert und eine vielfältige Einbaumöglichkeit erreicht werden kann.The invention is therefore based on the object of a plate heat exchanger of the type described at the beginning with simple constructive means such that the risk of media mixing is reduced, the efficiency improved and a variety of installation options can be achieved.
Die Erfindung löst die gestellte Aufgabe dadurch, daß die Durchtrittsöffnungen zumindest der Strömungswannen für eines der wärmeaustauschenden Medien im Bereich der Randstege liegen und miteinander über wenigstens einen außen an die Randstege der ineinandergesteckten Strömungswannen angeschlossenen Anschlußkasten für die Zu- bzw. Ableitung des Mediums verbunden sind.The invention solves the problem in that the passage openings at least the flow troughs for one of the heat exchanging media lie in the area of the edge webs and with each other via at least one outside connected to the edge webs of the nested flow troughs Connection box for the supply and discharge of the medium are connected.
Da zufolge dieser Maßnahmen die sonst für den Strömungsdurchtritt durch die Strömungswannen erforderlichen, tiefgezogenen Ansätze zumindest für eines der beiden wärmeaustauschenden Medien entfallen, weil dieses Medium durch die Durchtrittsöffnungen im Bereich der Randstege von außen zu- bzw. abgeführt wird, verringert sich die Anzahl der mediendicht auszuführenden Verbindungen zwischen den tiefgezogenen Ansätzen der Wannenböden und der jeweils anschließenden Strömungswanne wenigstens auf die Hälfte, womit die Gefahr einer undichten Verbindungsstelle entsprechend verringert wird. Der Fortfall der tiefgezogenen Ansätze zumindest für eines der wärmeaustauschenden Medien bringt außerdem eine Vergrößerung der wirksamen Wärmeaustauschfläche der durch die Wannenböden gebildeten Wärmetauscherplatten mit sich, so daß sich insgesamt günstige Konstruktionsverhältnisse ergeben, zumal sich aufgrund der parallelen Medienströmungen durch die zugehörigen Strömungswannen die Strömungswiderstände zwischen den Anschlußkasten für die Zu- und Ableitung des Mediums verringern. Der Anschluß der Anschlußkasten an der Außenseite der Randstege der ineinandergesteckten Strömungswannen ist selbstverständlich ebenfalls mediendicht vorzunehmen. Hiefür kann in üblicher Weise eine Löt- oder Schweißverbindung vorgesehen sein. Eine undichte Stelle im Bereich eines solchen Kastenanschlußes kann jedoch nur zu einem Austritt des Mediums, nicht aber zu einer Vermischung der Medien führen. Es braucht wohl nicht hervorgehoben zu werden, daß bei einer Zu- bzw. Ableitung von beiden wärmeaustauschenden Medien über Durchtrittsöffnungen im Bereich der Randstege der Strömungswannen alle die Strömungswannen durchsetzenden Strömungsverbindungen über tiefgezogene Ansätze entfallen, was zu besonders günstige Konstruktionsverhältnisse ergibt.As a result of these measures the otherwise for the flow passage through the Flow troughs, deep-drawn approaches required for at least one of the two heat exchanging media are eliminated because this medium is through the through openings in the area of the edge webs are fed in and out from the outside the number of connections that are media-tight can be reduced between the deep-drawn approaches of the tub bottoms and the each subsequent trough at least to half, which the Risk of a leaky connection point is reduced accordingly. Of the Elimination of the deep-drawn approaches at least for one of the heat-exchanging ones Media also brings an increase in the effective heat exchange area of the heat exchanger plates formed by the trough bottoms itself, so that overall there are favorable construction conditions, especially due to the parallel media flows through the associated flow troughs the flow resistances between the junction box for the Reduce the supply and discharge of the medium. The connection of the junction box on the outside of the edge webs of the nested flow troughs is of course also media-tight. This can be done in the usual way Way, a soldered or welded connection may be provided. A leak Position in the area of such a box connection can, however, only to one Leakage of the medium, but not lead to mixing of the media. It need not be emphasized that with a supply or discharge of both heat-exchanging media through openings in the area the edge webs of the flow troughs all penetrating the flow troughs Flow connections via deep-drawn approaches are no longer necessary results in particularly favorable design conditions.
Die Strömungsführung innerhalb der mit Anschlußkasten für die Zu- bzw. Ableitung eines Mediums verbundenen Strömungswannen kann durch die örtliche Zuordnung der Anschlußkasten mitbestimmt werden. Sind beispielsweise die Anschlußkasten für die Zu- und Ableitung eines Mediums auf einander gegenüberliegenden Seiten der Strömungswannen vorgesehen, so strömt das Medium im wesentlichen von der einen Seite der Strömungswannen zur gegenüberliegenden Seite. Werden hingegen die Anschlußkasten für die Zu- und Ableitung eines Mediums durch ein gemeinsames, mit Hilfe einer Trennwand in zwei Kammern unterteiltes Gehäuse gebildet, das an einer Seite der Strömungswannen angeschlossen ist, so kann eine Umlaufströmung des Mediums innerhalb der Strömungswannen erzwungen werden, insbesondere wenn die über das Gehäuse miteinander verbundenen Strömungswannen eine die Trennwand des Gehäuses fortsetzende Leiteinrichtung für die Mediumströmung aufweisen. Diese die Trennwand des Gehäuses fortsetzende Leiteinrichtung verhindert nämlich einen Strömungskurzschluß zwischen den parallel nebeneinander an die Strömungswannen angeschlossenen Gehäusekammern für die Zu- bzw. Ableitung des Mediums.The flow guidance within the with connection box for the supply or Derivation of a medium connected flow troughs can be done through the local assignment of the connection box can be determined. For example the connection box for the supply and discharge of a medium on each other provided opposite sides of the flow troughs, so that flows Medium essentially from one side of the flow troughs to the opposite Page. However, the junction box for the feed and Deriving a medium through a common one, using a partition in two-compartment subdivided housing formed on one side of the flow troughs is connected, a circulating flow of the medium inside the flow troughs are forced, especially when the over the housing interconnected flow troughs a the partition of the housing continuing guide device for the medium flow. This guiding device which continues the partition of the housing prevents namely a flow short circuit between the parallel side by side the housing connected to the flow troughs for the supply or Derivation of the medium.

Der Plattenwärmetauscher gemäß den Fig. 1 bis 3 ist aus einzelnen, ineinandergesteckten
Strömungswannen 1 aufgebaut, die jeweils aus einer den
Wannenboden bildenden Wärmetauscherplatte 2 mit einem hochgezogenen,
umlaufenden Randsteg 3 gebildet werden. Die Strömungswannen 1 sind mit
abwechselnd gegeneinander vorragenden, tiefgezogenen Ansätzen 4 versehen,
die Durchtrittsöffnungen 5 aufweisen. Da die im Bereich der Stirnseite flächig
aneinanderliegenden Ansätze 4 miteinander flüssigkeitsdicht verbunden sind,
ergeben sich über die Ansätze 4 jeweils flüssigkeitsdichte Durchtritte durch jede
zweite Strömungswanne 1, wie dies der Fig. 2 entnommen werden kann. Die
oberste Strömungswanne 1 ist mit einer Deckplatte 6 abgedeckt, die einen
Anschluß 7 für die Zuleitung und einen Anschluß 8 für die Ableitung eines der
beiden wärmeaustauschenden Medien, beispielsweise Öl, aufweist. Das über
den Anschluß 7 zugeführte, zu kühlende Öl durchströmt daher jede zweite Strömungswanne
1 des den Plattenwärmetauscher bildenden Wannenstapels, um
über den Anschluß 8 abgekühlt entnommen werden zu können. Das Kühlmittel,
z. B. Wasser, durchströmt die Strömungswannen 1, die zwischen den Strömungswannen
1 für die Ölführung liegen. Im Gegensatz zur Ölführung wird das
Wasser jedoch über außen an die Randstege 3 angeschlossene Anschlußkasten
9 für eine Zuleitung 10 und eine Ableitung 11 geführt, wobei die Verbindung
zwischen den Anschlußkasten 9 und den Strömungswannen 1 für die
Wasserführung über Durchtrittsöffnungen 12 im Bereich der Randstege 3 erfolgt.
Die Durchtrittsöffnungen 12 können in einfacher Weise durch entsprechende
schlitzförmige Ausnehmungen der Randstege 3 gebildet werden. Es ist aber
auch möglich, die Randstege 3 im Bereich der Durchtrittsöffnungen 12, zwischen
randseitigen Einschnitten nach außen aufzubiegen, um die Durchtrittsöffnungen
12 zu erhalten. Das über die Zuleitung 10 in den als Verteiler dienenden
Anschlußkasten 9 gepumpte Wasser strömt durch die Durchtrittsöffnungen 12
in die Strömungswannen 1 und tritt auf der gegenüberliegenden Wannenseite
über die Durchtrittsöffnungen 12 in den als Sammler dienenden Anschlußkasten
9 aus, von wo es über die Ableitung 11 abgeführt wird. Das Öl wird demnach
gemäß dem dargestellten Ausführungsbeispiel im Gegenstrom mit dem Kühlwasser
gekühlt. Die Strömungsverteilung innerhalb der Strömungswannen 1
kann durch Leiteinrichtungen, beispielsweise durch Turbulenzbleche 13 in
bekannter Weise beeinflußt werden.The plate heat exchanger according to FIGS. 1 to 3 is made of individual,
Der Plattenwärmetauscher gemäß dem Ausführungsbeispiel nach der Fig. 4
weist für die Zuleitung 10 und die Ableitung 11 des Kühlmittels ein gemeinsames
Gehäuse 14 auf, das durch eine Trennwand 15 in zwei Kammern 16
unterteilt ist, die die Anschlußkasten bilden. Dieses Gehäuse 14 ist auf einer
Außenseite des Plattenwärmetauschers angesetzt, der wie der Plattenwärmetauscher
gemäß den Fig. 1 bis 3 aus ineinandergesteckten Strömungswannen 1
aufgebaut ist. Um eine Umlaufströmung innerhalb der Strömungswannen 1 für
das Kühlmittel zu erzwingen, können innerhalb der Strömungswannen 1 die
Trennwand 15 fortsetzende Leiteinrichtungen 17 vorgesehen sein. Die Ölzufuhr
erfolgt wieder quer zu den Strömungswannen 1 über Aschlüsse 7 und 8 für die
Zu- und Ableitung.The plate heat exchanger according to the exemplary embodiment according to FIG. 4
has a common for the
Gemäß der Fig. 5 wird nicht nur das Kühlmittel über Anschlußkasten 9 für die
Zu- und die Ableitung 10, 11 den Strömungswannen 1 zugeführt, sondern auch
das zu kühlende Öl. Die Anschlußkasten 18 mit dem Anschluß 7 für die Zuleitung
und dem Anschluß 8 für die Ableitung des Öls sind dabei auf den einander
gegenüberliegenden Schmalseiten des Plattenwärmetauschers angeordnet,
während die Anschlußkasten 9 für das Kühlmittel auf den einander gegenüberliegenden
Längsseiten des Plattenwärmetauschers liegen, und zwar gegeneinader
versetzt. Die Anschlußkasten 9 und 18 sind jeweils über Durchtrittsöffnungen
im Bereich der Randstege 3 der Strömungswannen 1 mit den Strömungswannen
1 verbunden, so daß die Medienströmungen nicht durch tiefgezogene
Ansätze behindert werden. Die Wannenböden bilden daher auch nicht von
solchen teifgezogenen ansätzen unterbrochene Wärmetauscherplatten 2.5 is not only the coolant via
Die Erfindung ist selbstverständlich nicht auf die dargestellten Ausführungsbeispiele
beschränkt, die jedoch bereits zeigen, daß die gegenseitige Anordnung
der Anschlußkasten für die Zu- und Ableitung 10, 11 des einen der beiden
wärmeaustauschenden Medien sowie die Anschlüsse 7 und 8 für die Zu- und
Ableitung des jeweils anderen Mediums den jeweiligen Verhältnissen entsprechend
vielfältig variiert werden kann. Da außerdem die Grundrißform der Strömungswannen
1 weitgehend frei wählbar ist, können Plattenwärmetauscher für
sehr unterschiedliche Platzanforderungen in einfacher Weise zur Verfügung
gestellt werden, und zwar mit einem vorteilhaften Wirkungsgrad, weil einerseits
die Strömungswiderstände verringert und anderseits die durch den Grundriß der
Strömungswannen gegebenen möglichen Wärmetauscherflächen besser genützt
werden können.The invention is of course not based on the illustrated embodiments
limited, but which already show that the mutual arrangement
