Description
Die Erfindung betrifft einen gehäuselosen Plattenwärmetauscher, insbesondere flüssigkeitsgekühlten Ölkühler, mit einer Vielzahl verformter, ineinander gestapelter und ein Paket bildender Wärmetauscherplatten, die getrennte Strömungskanäle für wärmeaustauschende Medien aufweisen und mit austretenden Anschlüssen für die Zu-und Abführung mindestens eines Mediums sowie mit das Paket von Wärmetauscherplatten abschließender Grund-und Deckplatte und wahlweise mit einem aufgesetzten Ölfilter.The invention relates to a housing-free plate heat exchanger, in particular liquid-cooled Oil cooler, with a large number of deformed, stacked and stacked heat exchanger plates, which have separate flow channels for heat-exchanging media and with exiting connections for the supply and discharge of at least one medium and with the base plate and cover plate that complete the heat exchanger plates and optionally with an attached oil filter.
Nach dieser Beschreibung ausgebildete Ölkühler sind aus dem US-Patent Nr. 4 708 199 bekannt. Die in den verschiedenen Ausführungsformen gezeigten Ölkühler können sowohl glatte als verformte Deckplatten aufweisen. Die Deckplatten bilden im Falle eines aufgesetzten Ölfilters gleichzeitig die Abdichtungsfläche, unter Hinzufügung einer geeigneten Dichtung. Glatte Deckplatten sind hier dann vorgesehen, wenn radial abgehende Anschlüsse für das Kühlmedium unmittelbar unterhalb der Deckplatte angeordnet sind. (Fig. 15) Wenn verformte Deckplatten verwendet werden, befinden sich die Anschlüsse unten, im Bereich der Grundplatte, wie es beispielsweise in der Fig. 9 des US-Patentes gezeigt ist.Oil coolers designed in accordance with this description are known from U.S. Patent No. 4,708,199. The oil coolers shown in the various embodiments can be both smooth and deformed Have cover plates. In the case of an oil filter attached, the cover plates form simultaneously the sealing surface, with the addition of a suitable seal. Smooth cover plates are here provided if radially outgoing connections for the cooling medium immediately below the cover plate are arranged. (Fig. 15) If deformed cover plates are used the connections below, in the area of the base plate, as is the case, for example, in FIG. 9 of the US patent is shown.
Das Einsetzen der Anschlußstutzen im Bereich unterhalb der Deckplatte ist fertigungstechnisch von Nachteil, weil sich dieselben entweder in einer seitlichen Öffnung des vertikalen Randes der Deckplatte befinden oder auf diese Öffnung aufgesetzt sind. Sind die Anschlußstutzen aufgesetzt, müssen sie vor dem Löten provisorisch gehalten werden, was Vorrichtungen erfordert. Sind die Anschlußstutzen dagegen eingesetzt, muß das Maß der Löcher in der seitlichen vertikalen Wandung geringfügig größer sein, als der Durchmesser der Stutzen. Wegen der Beschichtung des Materials mit Lot, manchmal mit unterschiedlicher Schichtdicke, kann dieses Einsetzen demzufolge Schwierigkeiten bereiten. Ferner werden die Dichtigkeit und die Festigkeit der Lötverbindung auch durch die Größe der zu verbindenden Flächen beeinflußt. Da die Lötfläche hier relativ klein ist, kann es vermehrt zu undichten oder nicht ausreichende Festigkeit aufweisende Verbindungen kommen. Aus einem weiteren US-Patent mit der Nr. 860 823, das ebenfalls einen Wärmetauscher betrifft, allerdings einen nach einem völlig anderen Prinzip aufgebauten Wärmetauscher, bestehend aus Rohrplatten, die Strömungskanäle für ein flüssiges Medium bilden und dazwischen eingelegten Lamellen, durch die ein gasförmiges Medium (Luft) strömt, ist es bekannt, radial austretende Anschlußstutzen an den Sammelkästen (tank element 3) anzuordnen. Die Halbschalen der Sammelkästen besitzen halbrunde Anformungen, die beim Zusammenfügen der beiden Halbschalen die Anschlußstutzen in sich aufnehmen. Hierdurch wird eine größere Lötfläche zur Verfügung gestellt, so daß die Dichtheit der Lötverbindung im Vergleich zur davor beschriebenen Lösung verbessert ist. Hier ist jedoch die Kombination des Wärmetauschers mit einem über dem Wärmetauscher angeordneten Filter nicht vorgesehen. Dieser Wärmetauscher ist beispielsweise als Verdampfer einsetzbar, der sich im Kühlkreislauf einer Klimaanlage befinden könnte.The insertion of the connecting piece in the area below the cover plate is technically from Disadvantage because they are either in a lateral opening of the vertical edge of the cover plate located or placed on this opening. If the connecting pieces are attached, they are held temporarily before soldering, which requires devices. Are the connecting pieces used against it, the dimension of the holes in the lateral vertical wall be slightly larger than the diameter of the nozzle. Because of the coating of the material with solder, sometimes with different layer thickness, this insertion can therefore be difficult prepare. Furthermore, the tightness and strength of the solder joint are also through affects the size of the areas to be connected. Since the soldering area is relatively small here, it can increasingly leaky or insufficient strength connections. From another US patent no. 860 823, which also relates to a heat exchanger, however, a heat exchanger constructed according to a completely different principle, consisting of Pipe plates that form flow channels for a liquid medium and are inserted between them Slats through which a gaseous medium (air) flows, it is known, radially emerging connection piece to be arranged on the collection boxes (tank element 3). The half-shells of the collection boxes have semicircular formations, which when joining the two half shells Take up the connecting piece. This provides a larger soldering area, so that the tightness of the soldered connection is improved compared to the solution previously described is. However, here is the combination of the heat exchanger with one arranged above the heat exchanger Filters not provided. This heat exchanger can be used, for example, as an evaporator, which could be in the cooling circuit of an air conditioning system.
Die Aufgabe der Erfindung besteht darin, bei einem gehäuselosen Plattenwärmetauscher, insbesondere flüssigkeitsgekühltem Ölkühler, die Dichtigkeit der Anschlußstutzen zu verbessern, die Herstellung des Plattenwärmetauschers zu vereinfachen und eine günstige Anschlußmöglichkeit für den über dem Plattenwärmetauscher angeordneten Filter zur Verfügung zu stellen.The object of the invention is, in particular, in a case-less plate heat exchanger liquid-cooled oil cooler to improve the tightness of the connecting piece Simplify the manufacture of the plate heat exchanger and an inexpensive connection option for to provide the filter arranged above the plate heat exchanger.
Diese Aufgabe wird erfindungsgemäß durch die in den Patentansprüchen angegebenen Merkmale gelöst.This object is achieved by the features specified in the claims solved.
Danach weist die aus zwei zusammengefügten Teilen bestehende Deckplatte partiell über den Rand der Wärmetauscherplatten überstehende Bereiche auf, die halbschalenartig ausgebildete Abschnitte zur Aufnahme eines Anschlußstutzens besitzen, die über Öffnungen im unteren Teil der Deckplatte mit dem Strömungskanal des Mediums durch den Plattenwärmetauscher in Verbindung sind.Thereafter, the cover plate consisting of two parts joined partially over the On the edge of the heat exchanger plates projecting areas, the half-shell-shaped Have sections for receiving a connecting piece that have openings in the lower part of the Cover plate in connection with the flow channel of the medium through the plate heat exchanger are.
Die halbschalenartigen Abschnitte sind in ihrer Länge so gewählt, daß eine ausreichend große Lötfläche für die Anschlußstutzen innerhalb dieser Abschnitte zur Verfügung steht: Diese Abschnitte stehen vorzugsweise um einen geringen Betrag über den Rand der Wärmetauscherplatten, wodurch die Größe der Lötfläche variierbar ist. Ein wesentlicher Vorteil einer solchen Ausbildung besteht darin, daß die Lötverbindung in einem Arbeitsschritt erfolgen kann, ohne daß zusätzliche Hilfsvorrichtungen zum Verspannen der Teile nötig sind. Die Einwirkung einer Kraft von oben, die beim Löten solcher Plattenwärmetauscher in jedem Fall notwendig ist und die ganz einfach durch die Auflage eines Metallklotzes erzielt werden kann, ist völlig ausreichend, um auch die Anschlußstutzen mit hoher Qualität in den halbschalenartigen Abschnitten zu verlöten.The length of the half-shell-like sections is chosen so that a sufficiently large soldering area for the connecting pieces within these sections is available: These sections are preferably a small amount over the edge of the heat exchanger plates, whereby the size of the soldering area is variable. A major advantage of such training is in that the solder joint can be done in one step without additional Auxiliary devices for clamping the parts are necessary. The action of a force from above that when soldering such plate heat exchangers is necessary in any case and simply by the support of a metal block can be achieved is completely sufficient for the connecting piece to be soldered with high quality in the half-shell-like sections.
Der obere Teil der Deckplatte, also derjenige, der die Dichtfläche zum Filter bildet, weist eine kreisförmige Ausprägung auf, so daß die Dichtfläche ringförmig ausgebildet ist. In dieser Dichtfläche kann sich eine Ringdichtung befinden, d.h., die Dichtfläche besitzt ein umlaufende Sicke, in der die Ringdichtung eingelegt ist. Die Ausprägung dient gleichzeitig der Versteifung der Deckplatte und ermöglicht, geringere Blechdicken vorzusehen. Auch die untere Deckplatte kann eine Ausprägung zur Versteifung aufweisen.The upper part of the cover plate, ie the one that forms the sealing surface to the filter, has one circular shape, so that the sealing surface is annular. In this sealing surface there may be a ring seal, i.e. the sealing surface has a circumferential bead in which the ring seal is inserted. The expression serves at the same time to stiffen the cover plate and makes it possible to provide smaller sheet thicknesses. The lower cover plate can also be shaped have for stiffening.
Ferner befindet sich in beiden Teilen der Deckplatte mindestens eine zentrale Öffnung, in der in bekannter Weise eine Hohlschraube für den Rücklauf des Öles angeordnet ist, die weiterführt, bis zum darüber befindlichen Filter. Die nach innen, zu dieser zentralen Öffnung weisenden Ränder der kreisförmigen Ausprägung, können eine oder mehrere weitere Öffnungen besitzen, durch die das Öl in den Filter eintreten kann. Mit diesen Öffnungen korrespondierende Öffnungen sind auch im unteren Teil der Deckplatte angeordnet. Die Öffnungen stehen in hydraulischer Verbindung mit den Strömungskanälen für das zweite Medium durch den Plattenwärmetauscher.Furthermore, there is at least one central opening in both parts of the cover plate, in which known way a banjo bolt for the return of the oil is arranged, which continues until to the filter above. The edges of the inward facing this central opening circular shape, can have one or more additional openings through which the Oil can enter the filter. Apertures corresponding to these openings are also in the arranged lower part of the cover plate. The openings are in hydraulic connection with the Flow channels for the second medium through the plate heat exchanger.
Die Erfindung wird nachstehend anhand der beiliegenden Zeichnung erläutert.The invention is explained below with reference to the accompanying drawings.
Die einzige Fig. zeigt eine auseinandergezogene Darstellung des gehäuselosen Plattenwärmetauschers
1. Das Paket aus Wärmetauscherplatten 2 wurde unten prinzipiell abgebildet und ist in an
sich bekannter Weise ausgeformt, so daß getrennte Strömungskanäle 8 für das Kühlmittel und für
das Öl entstehen. Solche Plattenwärmetauscher 1 besitzen gewöhnlich eine etwas dickere untere
Grundplatte, die nicht gezeigt ist. The only figure shows an exploded view of the housing-less plate heat exchanger
1. The package of
Strömungspfeile 15 zeigen die Durchströmung des Plattenwärmetauschers 1 auf der Kühlmittelseite.
Die hier weniger interessierende Ölseite wurde nur durch Strömungsöffnungen 12 und die zentrale
Strömungsöffnung 13 angedeutet.
Das gesamte Paket ist mit den Deckplatten 3a; 3b zu einer fest gefügten Einheit mittels Löten verbunden.
Auch die Deckplatten 3a; 3b sind so miteinander dicht verlötet, daß zumindest die Vermischung
des Kühlmittels mit dem Öl ausgeschlossen ist und weder Kühlmittel noch Öl nach außen
austreten können. Selbstverständlich besteht auch eine Lötverbindung zur Trennung zwischen
Kühlmitteleintritt und -austritt. Hier sind jedoch geringe Undichtigkeiten ohne schwerwiegende Folgen.The entire package is with
Die untere Deckplatte 3b und die obere Deckplatte 3a sind durch Tiefziehen ausgeformte Teile. Die
obere Deckplatte 3a weist eine ringförmige, nach oben überstehende Ausprägung 9 auf, die zur
Auflage eines nicht gezeigten Ölfilters dient, aber gleichzeitig der Deckplatte 3a eine höhere Stabilität
verleiht, so daß diese aus einem dünneren Blech bestehen kann. Die Ausprägung 9 ist mit einer
ringförmigen Sicke 14 versehen, die zur Aufnahme eines Dichtungsringes vorgesehen ist. Die zentrale
Öffnung 13 dient der Zuführung des Öles in den Filter und auch der Rückführung des gefilterten
Öles. Die Zuführung des Öles könnte auch über nicht gezeigte Öffnungen innerhalb der Ausprägung
9 erfolgen.The lower cover plate 3b and the
Die halbschalenartigen Abschnitte 4 ragen über den Rand 10 des Plattenwärmetauschers 1. Sie
sind sowohl in der oberen Deckplatte 3a als auch in der darunter angeordneten Deckplatte 3b vorgesehen.
Die halbschalenartigen Abschnitte 4 leisten ebenfalls einen zusätzlichen Beitrag zur Erhöhung
der Steifigkeit der Deckplatte 3. In dem einen Abschnitt 4 befindet sich der Anschlußstutzen
5 für den Zulauf des Kühlmittels in den Plattenwärmetauscher 1 und in dem anderen Abschnitt 4 ist
dementsprechend der Anschlußstutzen 6 für den Rücklauf angeordnet. Die Abschnitte 4 in der
unteren Deckplatte 3b weisen etwa die gleiche Länge auf. Diese Länge entspricht etwa dem Überstand
der Deckplatte 3 über den Rand 10 des Paketes von Wärmetauscherplatten 2. Die obere
Deckplatte 3a hat dagegen längere Abschnitte 4, die darüber hinaus auch unterschiedlich lang sind.
Ihre Länge ist so gewählt, daß die in den Abschnitten 4 eingeschlossenen Anschlußstutzen 5 bzw.
6 in strömungstechnischer Verbindung mit den Öffnungen 7 bzw. dem Strömungskanal 8 stehen.
Die inneren Enden 16; 17 der Abschnitte 4 sind mit fließenden Übergängen versehen, um den
Strömungswiderstand für das Kühlmittel gering zu halten.The half-shell-
Die Anschlußstutzen 5 und 6 sind hier als gerade Stutzen ausgebildet. Je nach Einbaubedingung
des Plattenwärmetauschers 1 könnten hier selbstverständlich auch knieförmige Anschlußstutzen
zum Einsatz kommen.The
In den halbschalenartigen Abschnitten 4 sind Sicken 11 eingeprägt, die mit Sicken 11 um die Anschlußstutzen
5; 6 übereinstimmen. Diese Sicken 11 dienen der Lagepositionierung der Anschlußslutzen
5; 6 in den halbschalenartigen Abschnitten 4 und verbessern die Dichtigkeit und Festigkeit.In the half-shell-
