Definitions
- the invention relates to a heat exchanger in caseless plate design, in each case two deformed plates form a flat tube, which are stacked, wherein at one end of the stack of flat tubes an entrance collection box in the manner of a diffuser and at the other end an outlet collection box, for example for exhaust or charge air is arranged, which flows through the flat tubes and is thereby cooled by means of coolant, which is introduced and diverted via extending into the stack into the channels, wherein the channels are formed by means of connected openings in the deformed plates and wherein the channels with between the flow tubes are hydraulically connected to the flat tubes.
- exhaust heat exchangers in itself, including those that were proposed decades ago and used in heaters for cars of motor vehicles and come, bypassing the same with a bypass usually also required, among other things, because the heating demand is not permanently available.

- the flat tubes 3 are then stacked on each other, wherein the formation 80 comes to rest on the plate 1 or 2 of a flat tube 3 at the formation 80 of the plate 1 or 2 of the adjacent flat tube 3 . Only two cooled flat tubes 3 and only one uncooled flat tube 3 were shown in the exemplary embodiments.
- a collecting box 4 is arranged in the manner of a diffuser.
- a collecting box 5 is provided at the other end of a collecting box 5 , not shown. Both headers 4, 5 may be identical, except for the differences caused by the switching valve 20 , which are explained below.

- the circumferential formation 80 is approximately U - shaped in cross section, like the Fig. 3 and 4 best show.
- the heat exchanger has a cover plate 60 and a base plate 70 , which are also deformed and have a slightly larger sheet thickness than the deformed heat exchanger plates 1 and 2, to provide additional stability. Further, the base plate 70 and the cover plate 60 have been assigned a holding function for the switching valve 20 and the actuator 21 of the switching valve 20 . For this purpose, the base plate 70 and the cover plate 60 have each provided with a projection 90. At the projections 90 , the changeover valve 20 and the actuator 21 are mounted by means of a holder 91 . ( Fig. 1 )

- the way of interaction is from the Fig. 5 to recognize. From the Fig.
- the end 31 of the insulation plate 30 has been extended, this extended end 31 also cooperating with the flap 22 . It is advantageous not to form the flap 22 over a large area, because rattling noise or other functional disadvantages caused by the flow of the exhaust gas can occur.
- the flap 22 can be made smaller by the cooperation with the end 31 of the insulating plate 30 and with the functional element 23 , as shown in FIG Fig. 5 you can see.

Description
Die Erfindung betrifft einen Wärmetauscher in gehäuseloser Plattenbauweise, bei der jeweils zwei verformte Platten ein Flachrohr bilden, die gestapelt sind, wobei an einem Ende des Stapels der Flachrohre ein Eintrittssammelkasten in der Art eines Diffusors und am anderen Ende ein Austrittssammelkasten, beispielsweise für Abgas oder Ladeluft, angeordnet ist, das / die durch die Flachrohre strömt und dabei mittels Kühlmittel gekühlt wird, welches über in den Stapel hinein sich erstreckende Kanäle einleitbar und ausleitbar ist, wobei die Kanäle mittels verbundener Öffnungen in den verformten Platten gebildet sind und wobei die Kanäle mit zwischen den Flachrohren vorhandenen Strömungskanälen hydraulisch verbunden sind.The invention relates to a heat exchanger in caseless plate design, in each case two deformed plates form a flat tube, which are stacked, wherein at one end of the stack of flat tubes an entrance collection box in the manner of a diffuser and at the other end an outlet collection box, for example for exhaust or charge air is arranged, which flows through the flat tubes and is thereby cooled by means of coolant, which is introduced and diverted via extending into the stack into the channels, wherein the channels are formed by means of connected openings in the deformed plates and wherein the channels with between the flow tubes are hydraulically connected to the flat tubes.
Dieser gehäuselose Wärmetauscher wurde bereits in der
Die vorstehend beschriebene gehäuselose Plattenbauweise geht darüber hinaus aus dem der Anmelderin gehörenden
Gegenwärtig werden diese Wärmetauscher als Abgaswärmetauscher stark nachgefragt, weil zur Emissionsreduzierung bei Kraftfahrzeugen verstärkt der Weg der Abgasrückführung beschritten wird. Das rückgeführte Abgas muss gekühlt werden, um eine hohe Effizienz bei der Rückführung zu erreichen, insbesondere um bessere Füllungsgrade zu realisieren. Natürlich geht es um das Gesamtsystem "Kraftfahrzeug mit Verbrennungsmotor" und um eine insgesamt deutlich reduzierte Energiebilanz. Deshalb wurden bereits vor vielen Jahren sämtliche Betriebssituationen im Kraftfahrzeug analysiert und Maßnahmen getroffen, mit denen allen Betriebssituationen entsprochen werden kann. Eine dieser Maßnahmen besteht darin, den Abgaswärmetauscher in Betriebssituationen, in denen die Kühlung des Abgases kontraproduktiv wäre, mittels Bypässen zu umgehen. Solche Betriebssituationen sind insbesondere die extrem viel Kraftstoff benötigenden Startphasen des Kraftfahrzeuges, in denen die Wärmeenergie der Abgase beispielsweise direkt zur schnellen Aufwärmung des Motors auf seine optimale Betriebstemperatur herangezogen wird. Zur Umgehung des Abgaswärmetauschers werden gewöhnlich Lösungen vorgesehen, wie sie beispielsweise in den europäischen Patentanmeldungen / Patenten
Bei Abgaswärmetauschern an sich, also auch solchen die bereits vor Jahrzehnten vorgeschlagen und in Heizungen für Kabinen von Kraftfahrzeugen zum Einsatz kamen und kommen, ist die Umgehung desselben mit einem Bypass in der Regel auch erforderlich, u. a. deshalb, weil der Heizbedarf nicht permanent vorhanden ist. Aber auch diese Abgaswärmetauscher gehören gewöhnlich dem Rohrbündeltyp oder dem Spiralrohrtyp an. Hierzu zählen Abgaswärmetauscher, wie sie beispielsweise dem
Weitere Lösungen mit integrierten Bypässen, die jedoch keine Wärmetauscher in gehäuseloser Plattenbauweise betreffen und deshalb oft mittels aufwendiger Schweißverfahren hergestellt werden müssen, sind in der
Schlußfolgernd aus der vorstehenden Beschreibungseinleitung besteht die Aufgabe der Erfindung darin, Wärmetauscher in gehäuseloser Plattenbauweise derart mit einer Möglichkeit zur Umgehung, beispielsweise mittels Abgas oder Ladeluft, auszubilden, dass die vorbildlichen Funktionseigenschaften und die Kompaktheit erhalten bleiben, und dass sie vor allem herstellungsfreundlich bleiben.In conclusion, from the above description, the object of the invention is to heat exchanger in caseless plate design such with a way to bypass, for example by means of exhaust or charge air form, that the exemplary functional properties and compactness are maintained, and that they remain mainly production-friendly.
Die erfindungsgemäße Lösung erfolgt bei einem dem Oberbegriff entsprechenden Wärmetauscher entweder mit den kennzeichnenden Merkmalen des Anspruchs 1 oder mit den kennzeichnenden Merkmalen des Anspruchs 2. Gemäß der zweiten Variante ist vorgesehen, dass in einem der Sammelkästen ein Umschaltventil angeordnet ist, mit dem zumindest der überwiegende Anteil des rückzuführenden Abgasstroms entweder durch eine Mehrzahl von gekühlten Flachrohren des Stapels oder durch mindestens ein ungekühltes Flachrohr lenkbar ist, wobei zwischen den gekühlten und dem mindestens einen ungekühlten Flachrohr eine Isolationsplatte angeordnet ist, die mit einer verformten Platte des mindestens einen ungekühlten Flachrohres und mit einer verformten Platte eines gekühlten Flachrohres verbunden ist. Gemäß der ersten unabhängigen Aufgabenlösung kann auf die Isolationsplatte verzichtet werden, indem erfindungsgemäß in einem der Sammelkästen ein Umschaltventil angeordnet ist, mit dem zumindest der überwiegende Anteil des rückzuführenden Abgasstroms entweder durch eine Mehrzahl von gekühlten Flachrohren des Stapels oder durch mindestens ein ungekühltes Flachrohr lenkbar ist, wobei eine Trennung zwischen den gekühlten Flachrohren und dem mindestens einen ungekühlten Flachrohr durch den Verschluss der die Kanäle bildenden Öffnungen in mindestens einer der angrenzenden verformten Platten vorgesehen ist.The solution according to the invention is carried out in a heat exchanger according to the preamble either with the characterizing features of claim 1 or with the characterizing features of
Beide Lösungsvorschlage weisen zusätzlich einen nicht durchströmten Raum auf. Dieser Raum ist in dem Fall mit der Isolationsplatte zwischen dieser Platte und einer angrenzenden verformten Platte vorgesehen und im Fall ohne Isolationsplatte ist der Raum vorzugsweise zwischen zwei verformten Platten ausgebildet.Both proposed solutions also have a space not flowed through. This space is provided in the case with the insulating plate between this plate and an adjacent deformed plate, and in the case without the insulating plate, the space is preferably formed between two deformed plates.
Beide Lösungsvorschläge lösen unabhängig voneinander die gestellte Aufgabe, denn sie zielen auf einen herstellungsfreundlichen und kompakten Wärmetauscher in gehäuseloser Plattenbauweise.Both solutions independently solve the task, because they aim at a production-friendly and compact heat exchanger in caseless plate design.
Beide Lösungsvorschläge können jedoch auch gemeinsam an ein und demselben Wärmetauscher umgesetzt sein. Jedenfalls sollen die Ansprüche 1 und 2 so zu verstehen sein, dass eine Isolationsplatte laut Anspruch 2 vorgesehen sein kann und zusätzlich können die Öffnungen gemäß Anspruch 1 verschlossen sein, beispielsweise nicht ausgestanzt sein. Darüber hinaus kann der Verschluss auch durch Einlegen von Verschlussplatten in die Öffnungen hergestellt sein.However, both solutions can also be implemented together on one and the same heat exchanger. In any case, the
Obwohl das Vorsehen eines ungekühlten Flachrohres zum Zweck der Umgehung des Wärmetauschers bei Wärmetauschern mit einem Gehäuse zum Stand der Technik zählt, hat es nicht nahegelegen, diesen Gedanken auf gehäuselose Plattenwärmetauscher zu übertragen, weil nicht zu erwarten war, dass diese Maßnahme mit einfachen Mitteln auch bei gehäuselosen Plattenwärmetauschern machbar ist, ohne dass deren unbestreitbaren Vorteile aufgegeben werden müssen.Although the provision of an uncooled flat tube for the purpose of bypassing the heat exchanger in heat exchangers with a housing belongs to the prior art, it was not obvious to transfer this idea to caseless plate heat exchangers, because it was not expected that this measure with simple means caseless plate heat exchangers is feasible without their undeniable advantages must be abandoned.
Jede der verformten Platten ist mit einer umlaufenden Ausformung versehen, wie es bereits in dem
Von Vorteil ist es, wenn die gekühlten und die ungekühlten Flachrohre aus gleichen verformten Platten zusammengesetzt werden. Die Möglichkeit, das mindestens eine ungekühlte Flachrohr aus anderen verformten Platten zu bilden, ist trotzdem vorhanden. Beispielsweise kann das ungekühlte Flachrohr einen größeren Querschnitt aufweisen als ein gekühltes Flachrohr.It is advantageous if the cooled and the uncooled flat tubes are assembled from the same deformed plates. The possibility of forming the at least one uncooled flat tube from other deformed plates is still present. For example, the uncooled flat tube may have a larger cross section than a cooled flat tube.
Bei dem Lösungsvorschlag, der eine Isolationsplatte benötigt, ist es von Vorteil, wenn die Isolationsplatte ein über den Stapel überstehendes Ende aufweist, das mit dem Umschaltventil, insbesondere mit der Klappe des Umschaltventils, zusammenwirkt.In the proposed solution, which requires an insulation plate, it is advantageous if the insulation plate has a projecting end over the stack, which cooperates with the switching valve, in particular with the flap of the switching valve.
Die Wand des Sammelkastens, in dem sich das Umschaltventil befindet, weist zwei gegenüberliegende Öffnungen auf, in denen das Umschaltventil nach dem Löten des Wärmetauschers montiert werden kann. Von besonderem Vorteil der vorgeschlagenen Lösungen ist es, dass der gesamte beispielsweise Abgaswärmetauscher nach wie vor, bzw. trotz des integrierten Umschaltventils, in einer einzigen Lötoperation verbunden bzw. hergestellt werden kann. Dabei werden die Einzelteile des Abgaswärmetauschers durch die über die Enden der Flachrohre geschobenen Sammelkästen zusammengehalten. Aufwendige Schweißoperation, wie sie bei Wärmetauschern aus dem Stand der Technik notwendig sind, werden total vermieden. Wegen weiterer Merkmale wird auf die abhängigen Ansprüche verwiesen.The wall of the header, in which the change-over valve is located, has two opposing openings in which the change-over valve can be mounted after brazing the heat exchanger. It is of particular advantage of the proposed solutions that the entire exhaust gas heat exchanger, for example, can still be connected or produced in a single soldering operation, in spite of the integrated switchover valve. The individual parts of the exhaust gas heat exchanger are held together by the over the ends of the flat tubes pushed collecting tanks. Elaborate welding operation, as required in heat exchangers of the prior art, are totally avoided. For further features, reference is made to the dependent claims.

In dem gezeigten Ausführungsbeispiel handelt es sich um einen mittels Kühlflüssigkeit der Brennkraftmaschine gekühlten Abgaswärmetauscher für ein Kraftfahrzeug.In the exemplary embodiment shown, it is an exhaust gas heat exchanger cooled by means of coolant of the internal combustion engine for a motor vehicle.
Der Abgaswärmetauscher ist in gehäuseloser Plattenbauweise aufgebaut. Die Flachrohre 3 des Abgaswärmetauschers bestehen aus verformten Platten 1, 2. Die verformten Platten 1, 2 weisen eine umlaufende Ausformung 80 auf. Jeweils zwei verformte Platten 1, 2 bilden ein Flachrohr 3, wozu eine der Platten 1 oder 2 um 180° um ihre Längsachse gedreht und mit der anderen Platte zu einem Flachrohr 3 "Rand 102 an Rand 102" zusammengesetzt wird. Die Flachrohre 3 werden dann aufeinander gestapelt, wobei die Ausformung 80 an der Platte 1 oder 2 des einen Flachrohres 3 an der Ausformung 80 der Platte 1 oder 2 des benachbarten Flachrohres 3 zur Anlage kommt. Es wurden nur zwei gekühlte Flachrohre 3 und lediglich ein einziges ungekühltes Flachrohr 3 in den Ausführungsbeispielen gezeigt. Zweckmäßig ist es, die gekühlten Flachrohre 3 mit einem Inneneinsatz 99 zu versehen, wie es in der
Im Sammelkasten 4 ist ein Umschaltventil 20 angeordnet, mit dem zumindest der überwiegende Anteil des rückzuführenden Abgasstroms entweder durch eine Mehrzahl von gekühlten Flachrohren 3 des Stapels oder durch mindestens ein ungekühltes Flachrohr 3 lenkbar ist. Zwischen den gekühlten und dem mindestens einen ungekühlten Flachrohr 3 ist eine Isolationsplatte 30 angeordnet. Die im wesentlichen ebene Isolationsplatte 30 ist auf einer Seite mit einer verformten Platte 1 des mindestens einen ungekühlten Flachrohres 3 und auf der anderen Seite mit einer verformten Platte 2 des angrenzenden gekühlten Flachrohres 3 verbunden. Speziell sieht die erwähnte Verbindung so aus, dass die Isolationsplatte 30 an der umlaufenden Ausformung 80 der beiden verformten Platten 1, 2 anliegt und damit verbunden ist. Deshalb bleibt innerhalb des von der umlaufenden Ausformung 80 umgebenden Raums zwischen der Isolationsplatte 30 und den verformten Platten 1, 2 ein nicht durchströmter Raum 101 übrig, der thermisch isolierende Eigenschaften besitzt.

Der Wärmetauscher besitzt eine Deckplatte 60 und eine Grundplatte 70, die ebenfalls verformt sind und eine etwas größere Blechdicke aufweisen als die verformten Wärmetauscherplatten 1 und 2, um für zusätzliche Stabilität zu sorgen. Ferner wurde der Grundplatte 70 und der Deckplatte 60 eine Halte - bzw. Befestigungsfunktion für das Umschaltventil 20 und für das Stellelement 21 des Umschaltventils 20 zugeordnet. Zu diesem Zweck hat man die Grundplatte 70 und die Deckplatte 60 mit je einem Vorsprung 90 versehen. An den Vorsprüngen 90 werden, mittels eines Halters 91, das Umschaltventil 20 und das Stellelement 21 montiert. (
