Die Erfindung betrifft einen Anschlußadapter für Plattenwärmetauscher, zur Zu-und/oder Ableitung von Medien, der an einer Seite des Wärmetauschers befestigt und mit den Strömungskanälen des Wärmetauschers in hydraulischer Verbindung ist.The invention relates to a connection adapter for plate heat exchangers, for supply and / or discharge of media that is attached to one side of the heat exchanger and with the flow channels of the Heat exchanger is in hydraulic connection.
Ein solcher Anschlußadapter ist aus der WO 94/29659; F28D 9/00, bekannt. Der Anschlußadapter ist Teil eines Plattenwärmetauschers und ist an einer Seite des Plattenwärmetauschers angeordnet. Er dient hier dazu, den Zulauf und den Ablauf einer Flüssigkeit in oder von dem Plattenwärmetauscher zu ermöglichen. Ferner kann der Adapter mit einer Befestigungsplatte für den Plattenwärmetauscher verbunden sein.Such a connection adapter is known from WO 94/29659; F28D 9/00, known.

It is used here for the inlet and outlet of a liquid in or from the plate heat exchanger to enable. Furthermore, the adapter with a mounting plate for the plate heat exchanger be connected.
Der Hauptzweck des Adapters besteht hier wohl darin, daß mittels des Adapters variable Anschlußmöglichkeiten für den Wärmetauscher auf einfache Weise geschaffen worden sind, weil in der Adapterplatte ein Kanal als Verbindung zwischen dem Flüssigkeitszulauf und dem Flüssigkeitsablauf eingearbeitet ist, der es zuläßt, beispielsweise den Anschlußflansch dort zu positionieren, wo es von den Einbaubedingungen her günstig ist. Der Kanal muß dann so ausgebildet werden, daß er den Flüssigkeitszulauf mit dem Flüssigkeitsablauf verbindet, d. h., er wird für verschiedene Einbauverhältnisse auch verschieden ausgeformt sein.The main purpose of the adapter here is probably that by means of the adapter variable connection options have been created for the heat exchanger in a simple manner because in the adapter plate a channel as a connection between the liquid inlet and the liquid outlet is incorporated, which allows, for example, to position the connecting flange where it is favorable from the installation conditions. The channel must then be designed so that it connects the liquid inlet to the liquid outlet, d. that is, it is used for different installation conditions also be shaped differently.
Dieser Anschlußadapter ist jedoch nur für die Zu-und/oder Abführung eines einzigen Mediums vorgesehen. Sollen mehrere Medien, beispielsweise zwei, über einen Anschluß getrennt voneinander zu-und/oder abgeführt werden, ist dieser Anschlußadapter nicht geeignet.However, this connection adapter is only intended for the supply and / or discharge of a single medium. Should several media, for example two, be separated from each other via a connection this connection adapter is not suitable.
Aus der nicht vorveröffentlichten DE 195 19 740 A1 ist ein Wärmetauscher bekannt, der an einer Seite eine Verteilerplatte besitzt, die Ausschnitte und Bohrungen aufweist. Diese Verteilerplatte ist gemeinsam mit einer weiteren Befestigungsplatte so am Wärmetauscher befestigt, daß die Ausschnitte und Bohrungen in hydraulischer Verbindung mit den Strömungskanälen im Wärmetauscher sind. Dieser Wärmetauscher bietet u.a. nicht die Möglichkeit, zwei Medien, getrennt voneinander, in einen einzigen Strömungskanal einzuleiten.A heat exchanger is known from the unpublished DE 195 19 740 A1, which is connected to a Side has a distributor plate, which has cutouts and holes. This distribution plate is attached to the heat exchanger together with another mounting plate so that the cutouts and holes in hydraulic connection with the flow channels in the heat exchanger are. This heat exchanger offers i.a. not the ability to separate two media into each other to initiate a single flow channel.
Der Ölkühler aus DE 30 20 557 Al weist Bauteile wie Anschlußplatte, Strömungselement im Strömungskanal und ein Trennelement im Strömungskanal auf. Diese Bauteile dienen der Umlenkung des Öles innerhalb des Ölkühlers, um dessen Kühlleistung zu erhöhen. Auch hiermit können nicht zwei Medien in einen Strömungskanal eingeleitet werden.The oil cooler from DE 30 20 557 Al has components such as connecting plate, flow element in the flow channel and a separator in the flow channel. These components serve to redirect of the oil inside the oil cooler to increase its cooling capacity. Even with this you cannot two media can be introduced into a flow channel.
Die Aufgabe der Erfindung besteht darin, den Anschlußadapter so zu verbessern, daß er für die getrennte Zu-und/oder Abführung von zwei Medien geeignet ist und beispielsweise als Anschlußadapter für Plattenwärmetauscher mit mehr als zwei getrennten Medien verwendet werden kann. Die erfindungsgemäße Lösung ergibt sich aus den Patentansprüchen.The object of the invention is to improve the connection adapter so that it for separate supply and / or discharge of two media is suitable and for example as a connection adapter can be used for plate heat exchangers with more than two separate media. The solution according to the invention results from the patent claims.
Es ist vorgesehen, daß der Anschlußadapter aus einer Anschlußplatte, einem vorzugsweise rohrartigen Strömungselement und einem Trennelement, vorzugsweise einer Ringscheibe besteht. Die Anschlußplatte weist zwei Bohrungen auf, jeweils eine für ein Medium. Eine der Bohrungen nimmt ein Ende des rohrartigen Strömungselementes auf, das mit dem anderen Ende in den Strömungskanal des Wärmetauschers hineinragt. Der Durchmesser des Strömungselementes ist geringer als derjenige des Strömungskanales, so daß dazwischen ein Spalt ausgebildet ist, der als Strömungskanal dienlich ist. Das erwähnte andere Ende des rohrartigen Strömungskanales ist mit dem Trennelement verbunden, das als Ringscheibe ausgebildet ist. Und zwar ist die Ringscheibe mit dem inneren Rand am Strömungselement abdichtend befestigt, beispielsweise gelötet und mit dem äußeren Rand abdichtend zwischen horizontalen Kanälen des Wärmetauschers eingebaut. In Verbindung mit der zweiten Bohrung stehend, ist ein Verbindungskanal in der Anschlußplatte ausgebildet, der andererseits zu dem erwähnten Spalt führt. Der wie beschrieben ausgebildete Anschlußadapter ist für die getrennte Zu-und/oder Abführung von zwei Medien in bester Weise geeignet. Das eine Medium tritt durch die eine Bohrung ein, fließt durch das Strömungselement in den Wärmetauscher, wo es sich in den horizontalen Kanälen ausbreitet und am Wärmeaustausch teilnimmt. Das andere Medium tritt durch die andere Bohrung ein oder aus, strömt über den Verbindungskanal, tritt in den Spalt ein, um von dort zu den horizontalen Kanälen des Wärmetauschers zu gelangen, um ebenfalls am Wärmeaustausch teilzunehmen.It is provided that the connection adapter consists of a connection plate, preferably a tubular one Flow element and a separating element, preferably an annular disc. The Connection plate has two holes, one for a medium. One of the holes is taking one end of the tubular flow element, which with the other end in the flow channel of the heat exchanger protrudes. The diameter of the flow element is less than that of the flow channel, so that a gap is formed between them, the flow channel is useful. The mentioned other end of the tubular flow channel is with the separating element connected, which is designed as an annular disc. And that's the washer with that inner edge attached to the flow element sealingly, for example soldered and with the outer Edge sealed between horizontal channels of the heat exchanger. In connection standing with the second hole, a connecting channel is formed in the connection plate, which on the other hand leads to the mentioned gap. The connection adapter designed as described is best suited for the separate supply and / or discharge of two media. The one Medium enters through one hole, flows through the flow element into the heat exchanger, where it spreads in the horizontal channels and participates in heat exchange. The other medium enters or exits through the other hole, flows through the connecting channel, and emerges into the gap to get from there to the horizontal channels of the heat exchanger also participate in the heat exchange.
Der Anschlußadapter kann beispielsweise mit einer Deckplatte des Wärmeaustauschers fest und dicht verlötet sein. Hinsichtlich der Variabilität von Anschlußmöglichkeiten kann eine Verbesserung dadurch erreicht werden, daß die zweite Bohrung dort in der Anschlußplatte vorgesehen und mit dem Verbindungskanal verbunden ist, wo es von den Einbaubedingungen her günstig ist.The connection adapter can, for example, be fixed with a cover plate of the heat exchanger be tightly soldered. With regard to the variability of connection options, there can be an improvement can be achieved in that the second bore is provided there in the connection plate and with the connection channel is connected where it is favorable from the installation conditions.
Der erfindungsgemäße Anschlußadapter ist vorzüglich für Plattenwärmetauscher geeignet, die mehrere, beispielsweise vier getrennte Kreisläufe innerhalb des einen Wärmetauschers aufweisen. Beispielsweise können zwei solche Adapter, einer für den Zulauf der zwei Medien, einer für den Ablauf der zwei Medien an einer Seite des Plattenwärmetauschers angeordnet sein. Wenn der erwähnte Strömungskanal des Wärmetauschers abgeschottet ist, beispielsweise durch eine weitere Trennscheibe, könnten von der gegenüberliegenden Seite des Plattenwärmetauschers weitere zwei getrennte Medien zu-und abgeführt werden, so daß sogar vier getrennte Medien am Wärmeaustausch beteiligt sein können.The connection adapter according to the invention is particularly suitable for plate heat exchangers have several, for example four separate circuits within the one heat exchanger. For example, two such adapters, one for the inlet of the two media, one for the Drain the two media to be arranged on one side of the plate heat exchanger. If the mentioned flow channel of the heat exchanger is sealed off, for example by another Cutting disc, could be from the opposite side of the plate heat exchanger two separate media can be fed in and out, so that even four separate media are used for heat exchange can be involved.
Ist der Anschlußadapter in einem gelöteten Plattenwärmetauscher eingebaut, ist es vorzuziehen, wenn auch die Bestandteile des Anschlußadapters Einzelteile sind, die gemeinsam mit dem Plattenwärmetauscher im Lötofen verbunden werden. Jedoch bei Wärmetauschern, die lösbar, unter Verwendung von Dichtungen verbunden sind, kann der Anschlußadapter auch beispielsweise als Kunststoff-Spritzgußteil ausgeführt sein.If the connection adapter is installed in a soldered plate heat exchanger, it is preferable to even if the components of the connection adapter are individual parts that work together with the plate heat exchanger be connected in the soldering furnace. However, with heat exchangers that are detachable, under Use of seals are connected, the connection adapter can also, for example, as Plastic injection molded part.

daß auch der Anschlußadapter 1 sowohl in sich als auch im Plattenwärmetauscher gelötet ist. Der
Anschlußadapter 1 besteht aus den drei Einzelteilen, nämlich Anschlußplatte 2, Strömungselement
3 und Trennelement 4, das als Ringscheibe 40 ausgebildet ist.The embodiment shows a plate heat exchanger in a completely soldered design, see above

gezeichnet worden. Diese andere Variante ist nicht für gelötete sondern für mit Dichtungen zusammengefügte
Wärmetauscher vorgesehen.The other variant, in which these
Die Elemente des Wärmetauschers werden in an sich bekannter Weise zusammengefügt, wobei
auch die Ringscheibe 40 mit ihrem äußeren Rand 42 zwischen den Wärmetauscherplatten 7 eingefügt
wird. Außerdem werden das Strömungelement 3 und die Anschlußplatte 2 mit eingelegt. Der
innere Rand 41 der Ringscheibe 40 ist in Kontakt mit dem Strömungselement 3, vorzugsweise mit
dessen Ende 31, das sich im Strömungskanal 6 des Wärmetauschers befindet. Selbstverständlich
könnte dieses Ende 31 auch etwas tiefer in den Strömungskanal 6 hineinragen als nur bis zu der
Stelle, wo sich die Ringscheibe 40 befindet. Strömungstechnisch dürfte es jedoch vorzuziehen sein,
wenn sich die Ringscheibe 40 am Ende 31 des Strömungselementes 3 befindet. Im übrigen richtet
sich die Einsatztiefe des Strömungselementes 3 nach den geforderten Leistungsparametern. In Fig.
1 sind beispielsweise nur die oberen zwei horizontalen Kanäle 8 des Wärmetauschers von den
anderen horizontalen Kanälen abgetrennt.The elements of the heat exchanger are assembled in a manner known per se, wherein
also the
Der Plattenwärmetauscher weist ferner selbstverständlich noch weitere Strömungskanäle für das
Kühlmedium auf, die den gesamten Stapel der Wärmetauscherplatten 7 durchsetzen. Die horizontalen
Kanäle 8 für die zu kühlenden Medien wechseln sich mit ebensolchen für das Kühlmedium ab.The plate heat exchanger naturally also has further flow channels for the
Cooling medium that penetrate the entire stack of heat exchanger plates 7. The
Ein weiteres abgetrenntes zu kühlendes Medium wird in Fig. 1 von der dem Anschlußadapter 1
gegenüberliegenden Seite zu-und abgeführt. Die Strömungspfeile machen dies deutlich. An dieser
gegenüberliegenden Seite könnte beispielsweise ebenfalls ein Anschlußadapter 1 vorgesehen werden.
Zur Trennung der von gegenüberliegenden Seiten zugeführten Medien, ist eine Trennscheibe
9 im Strömungskanal 6 zwischen den Wärmetauscherplatten 7 angeordnet.A further separated medium to be cooled is shown in FIG. 1 by the connection adapter 1
opposite side in and out. The flow arrows make this clear. At this
opposite side, for example, a connection adapter 1 could also be provided.
To separate the media fed from opposite sides, there is a
Die Anschlußplatte 2 des Anschlußadapters 1 besitzt zwei Bohrungen 20 und 23. Die größere Bohrung
20 nimmt das Ende 30 des Strömungselementes 3 auf, das dort dicht verlötet ist. Die kleinere
Bohrung 23 führt zu einem Verbindungskanal 21, der diese Bohrung 23 mit dem Spalt 5, einem
Ringspalt, verbindet. Ein Medium strömt nun durch die größere Bohrung 20 und das Strömungselement

Fig. 2 zeigt prinzipiell eine Ansicht von oben, wobei, wie man erkennen kann, die Größenverhätnisse
nicht ganz die gleichen sind. In zwei diagonal gegenüberliegenden Ecken sind Anschlußadapter
1 angeordnet - einer für die Zuführung und der andere für die Abführung der zwei Medien. Die Bezugszeichen
sind nur bei dem im Bild oberen Anschlußadapter 1 eingetragen worden. Die beiden
Bohrungen 20 und 23 gehen daraus hervor und je zwei weitere Bohrungen 22, die der abgedichteten
Befestigung von Anschlußflanschen dienen. Die Oberfläche der Anschlußplatte 2 ist gewöhnlich
eine sehr ebene Fläche.Fig. 2 shows in principle a view from above, wherein, as can be seen, the size ratios
are not quite the same. There are connection adapters in two diagonally opposite corners

entgegenkommt. Der Verbindungskanal 21 befindet sich jedoch in jedem Fall
zwischen der einen, vorliegend der kleinen Bohrung 23 und dem Spalt 5. Außerdem kann das Größenverhältnis
der Bohrungen 20 und 23 frei gewählt und den Bedingungen angepaßt werden.From Fig. 2 it can also be clearly seen that the arrangement of the small bore 23 to the large one
