Description

Die Erfindung betrifft eine Trennblechdichtung für einen Wärmetauscher mit Lamellen, die eine Abwinklung zur federnden Anlage an einem Wärmetauschermantel aufweisen, wobei die Lamellen in einem Lamellenträger angeordnet sind, der eine Aufnahmenut für ein Trennblech aufweist. Weiterhin betrifft die Erfindung einen Wärmetauscher mit einer Trennblechdichtung.The invention relates to a partition plate seal for a heat exchanger with fins, which have an angled portion for resilient engagement with a heat exchanger jacket, wherein the fins are arranged in a plate carrier having a receiving groove for a separating plate. Furthermore, the invention relates to a heat exchanger with a baffle seal.

Die DE 10 2010 038 751 A1 betrifft einen Wärmetauscher zum Heizen oder Kühlen eines Luftstroms mit zumindest zwei nebeneinander angeordneten und von einem Fluid durchströmbaren Rohrabschnitten. Zwischen den Rohrabschnitten ist ein von dem Luftstrom durchströmbares Lamellenprofil angeordnet. Zur Abdichtung der Rohrabschnitte sind elastische Dichtungs- und Ausgleichselemente vorgesehen.The DE 10 2010 038 751 A1 relates to a heat exchanger for heating or cooling an air flow with at least two pipe sections arranged side by side and through which a fluid can flow. Between the pipe sections a through-flow of the air flow lamellar profile is arranged. To seal the pipe sections elastic sealing and compensation elements are provided.

Aus der EP 0 656 517 B1 ist ein Wasser/Luft-Wärmetauscher aus Aluminium oder einer Aluminium-Legierung für ein Kraftfahrzeug bekannt. An einem Kopf des Wärmetauschers ist ein Trennblech angeordnet, welches einen Zulauf vor einem Ablauf trennt und zu seiner Anordnung auf einem Rohrboden mit Nuten und Zähnen versehen ist.From the EP 0 656 517 B1 For example, a water / air heat exchanger made of aluminum or an aluminum alloy for a motor vehicle is known. At a head of the heat exchanger, a separating plate is arranged, which separates an inlet from a drain and is provided for its arrangement on a tube plate with grooves and teeth.

Trennblechdichtungen werden zur Abdichtung des Spaltes zwischen dem Längstrennblech und dem Mantel des Wärmetauschers eingesetzt. Einer wirksamen Trennung kommt insbesondere bei Hochleistungswärmetauschern besondere Bedeutung zu, da vor allem bei kleinen Temperaturdifferenzen bereits geringe Kurzschlussströmungen zu beachtlichen Leistungsverlusten führen. Dies lässt sich durch Einsatz von Trennblechdichtungen weitgehend verhindern.Separator plate seals are used to seal the gap between the longitudinal dividing plate and the jacket of the heat exchanger. Effective separation is of particular importance in the case of high-performance heat exchangers, since small short-circuit currents, even at low temperature differences, lead to considerable power losses. This can be largely prevented by using separating plate seals.

In der DE 2 712 207 B2 wird ein Wärmetauscher mit einem zylindrischen Wärmetauschermantel beschrieben. In dem Wärmetauschermantel ist ein raumteilendes Trennblech eingesetzt. An der Trennblechlängsseite ist zwischen dem Trennblech und dem Wärmetauschermantel eine Trennblechdichtung angeordnet.In the DE 2 712 207 B2 a heat exchanger with a cylindrical heat exchanger jacket is described. In the heat exchanger jacket, a room-dividing partition is used. At the separating plate longitudinal side, a separating plate seal is arranged between the separating plate and the heat exchanger jacket.

Darüber hinaus sind Trennblechdichtungen bekannt, die Lamellen umfassen, welche am Wärmetauschermantel anliegen. Entsprechende Trennblechdich-tungen werden von der Kempchen Dichtungstechnik GmbH mit der Produktbezeichnung T4 vertrieben ( Katalog der Kempchen Dichtungstechnik GmbH, Stand Juni 2012, Seiten 117-118 ). Die Lamellen weisen eine Abwinklung auf, die eine Federwirkung gewährleistet. Die Lamellen sind in einem Lamellenträger angeordnet. Der Lamellenträger umfasst eine Aufnahmenut die zum Aufschieben der Trennblechdichtung auf das Längstrennblech dient. Das Trennblech wird in die Aufnahmenut geschoben bis es am Boden der Aufnahmenut anschlägt. Die Lamellen sind im Lamellenträger so fixiert, dass sie ausgehend vom Boden der Aufnahmenut abwinkeln. Bei der Konstruktion des Wärmetauschers ist dabei darauf zu achten, dass der Spalt zwischen Trennblech und Wärmetauschermantel möglich klein ist. Die Abdichtung zwischen den Räumen des Wärmetauschers erfolgt durch Anliegen der Lamellen an der Innenseite des Wärmetauschermantels. Durch das Einspannen der Lamellen am Lamellenträger und die federnde Wirkung ergibt sich eine ausreichende Anpresskraft, mit der die Lamellen an die Innenwand des Wärmetauschermantels gepresst werden.In addition, separating plate seals are known which comprise lamellae which rest against the heat exchanger jacket. Corresponding baffle gaskets are sold by Kempchen Dichtungstechnik GmbH with the product name T4 ( Catalog of Kempchen Dichtungstechnik GmbH, June 2012, pages 117-118 ). The slats have an angling, which ensures a spring action. The slats are arranged in a plate carrier. The plate carrier comprises a receiving groove which serves to push the separating plate seal onto the longitudinal separating plate. The separating plate is pushed into the receiving groove until it hits the bottom of the receiving groove. The lamellae are fixed in the plate carrier in such a way that they angle away from the bottom of the receiving groove. When designing the heat exchanger, make sure that the gap between the separating plate and the heat exchanger jacket is small. The seal between the chambers of the heat exchanger is made by concerns of the fins on the inside of the heat exchanger shell. By clamping the lamellae on the plate carrier and the resilient action results in a sufficient contact force with which the lamellae are pressed against the inner wall of the heat exchanger shell.

Je größer der Spalt zwischen dem Trennblech und dem Wärmetauschermantel ist, desto geringer ist die Anpresskraft mit der die Lamellen gegen die Wärmetauschermantelwand gedrückt werden. Ab einer gewissen Spaltgröße kann eine Abdichtung nicht mehr gewährleistet werden, so dass Leistungsverluste am Wärmetauscher auftreten. Insbesondere problematisch ist der Einsatz von herkömmlichen Trennblechdichtungen als Ersatz bei bereits bestehenden Wärmetauschern. Beim Betrieb von Wärmetauschern kommt es dazu, dass sich diese Verziehen oder sich Verschmutzungen absetzen. Aufgrund des Verzuges kann sich ein größerer Spalt bilden. Ebenso kann es bei der Aufarbeitung von bereits gebrauchten Wärmetauschern beispielsweise durch Ausdrehen zu erheblichen Maßabweichungen kommen, so dass zum Teil große Spalte zwischen dem Trennblech und der Innenwand des Wärmetauschermantels auftreten.The larger the gap between the separating plate and the heat exchanger jacket, the lower the contact pressure with which the lamellae are pressed against the heat exchanger jacket wall. From a certain gap size, a seal can no longer be guaranteed, so that power losses on Heat exchangers occur. Particularly problematic is the use of conventional partition seals as a replacement for existing heat exchangers. When operating heat exchangers, these warping or soiling settle. Due to the delay, a larger gap can form. Likewise, in the work-up of already used heat exchangers, for example, by turning out to considerable deviations may occur, so that sometimes large gaps between the separating plate and the inner wall of the heat exchanger shell occur.

Aufgabe der Erfindung ist es, eine Trennblechdichtung für einen Wärmetauscher anzugeben, die einen möglichst großen Einsatzbereich hat. Die Trennblechdichtung soll mit möglichst geringem Aufwand in bereits bestehenden Wärmetauschersysteme, beispielsweise auch als Ersatzteil, einsetzbar sein. Sie soll dabei auch in der Lage sein, bestehende Trennblechdichtungen zu ersetzen, ohne dass ein großer Anpassungsaufwand dafür erforderlich ist. Zudem soll die Trennblechdichtung eine effiziente Trennung von Räumen innerhalb des Wärmetauschers gewährleisten, so dass Leistungsverluste vermieden werden. Zudem soll sich die Trennblechdichtung durch eine einfache und preiswerte Herstellung auszeichnen und dabei eine hohe Qualität bieten, so dass auch über einen langen Betriebszeitraum eine Abdichtung gewährleistet bleibt.The object of the invention is to provide a baffle plate for a heat exchanger, which has the largest possible application. The baffle plate should be used with the least possible effort in existing heat exchanger systems, for example, as a spare part. It should also be able to replace existing baffle seals, without a great adaptation effort is required. In addition, the baffle seal should ensure efficient separation of spaces within the heat exchanger, so that power losses are avoided. In addition, the baffle seal should be characterized by a simple and inexpensive production and thereby offer a high quality, so that even over a long period of operation a seal remains guaranteed.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Boden der Aufnahmenut gegenüber der Abwinklung der Lamellen um einen Abstand zur Mitte des Wärmetauschermantels versetzt angeordnet ist. Somit schließt im Gegensatz zu herkömmlichen Trennblechdichtungen der Boden der Aufnahmenut nicht bündig mit der Abwinklung der Lamellen ab, sondern ist zur Mittelachse des Mantels des Wärmetauschers verschoben. Diese Konstruktion ermöglicht es, dass größere Spalte zwischen dem Längstrennblech und dem Mantel überbrückt werden können, ohne dass die Anpresskraft der Lamellen am Wärmetauschermantel abnimmt. Grundsätzlich würde es zunächst in Betracht kommen, die Konstruktion der bekannten Trennblechdichtung beizubehalten und abhängig von einem erweiterten Spaltmaß neu zu skalieren, wodurch sich längere Lamellen ergeben würden. Der Erfindung liegt jedoch davon ausgehend die Erkenntnis zugrunde, dass dann die Anpresskraft bei gleichem Material der Lamellen abnehmen würde und eine Abdichtung nicht mehr gewährleistet wäre.This object is achieved in that the bottom of the receiving groove is offset from the bending of the slats offset by a distance to the center of the heat exchanger shell. Thus, in contrast to conventional baffle seals, the bottom of the receiving groove is not flush with the angling of the fins, but is displaced to the central axis of the jacket of the heat exchanger. This design makes it possible to bridge larger gaps between the longitudinal partition plate and the jacket, without the contact force of the lamellae on the heat exchanger jacket decreases. In principle, it would initially be considered to maintain the design of the known baffle seal and rescale depending on an extended gap, resulting in longer fins would result. However, the invention is based on the knowledge that then the contact force would decrease with the same material of the slats and a seal would not be guaranteed.

Mit der erfindungsgemäßen Vorrichtung können auf einfache Weise Dichtungen von wieder aufgearbeiteten Wärmetauschern ersetzt werden. Da beim Wiederaufarbeiten des Wärmetauschers durch Ausdrehen größere Spalte entstehen bzw. durch den Gebrauch aufgrund des Verzuges sich größere Spalte bilden, kann der Einsatz von herkömmlichen Trennblechdichtungen zu einer schlechteren Abdichtung führen. Bei der erfindungsgemäßen Trennblechdichtung bleibt der Abstand der Abwinkelstelle zum Wärmetauschermantel weitgehend gleich wie bei der ursprünglichen Dichtung. Dadurch bleibt die Anpresskraft auch weitgehend gleich, so dass eine Trennung der einzelnen Räume im Wärmetauscher gewährleistet bleibt, ohne dass zu es Leistungsverlusten im Wärmetauscher kommt. Der größere Spalt wird erfindungsgemäß durch Verschiebung des Bodens der Aufnahmenut des Lamellenträgers kompensiert. Der Boden der Aufnahmenut ist zur Mittelachse des zylindrischen Wärmetauschermantels hin verschoben.With the device according to the invention can be replaced in a simple way seals of recycled heat exchangers. Since the refurbishment of the heat exchanger by turning out larger gaps or caused by the use due to the delay form larger gaps, the use of conventional baffle seals can lead to a poorer seal. In the partition seal according to the invention, the distance of the Abwinkelstelle to the heat exchanger jacket remains largely the same as in the original seal. As a result, the contact pressure also remains largely the same, so that a separation of the individual rooms is ensured in the heat exchanger, without causing power losses in the heat exchanger. The larger gap is compensated according to the invention by displacement of the bottom of the receiving groove of the disk carrier. The bottom of the receiving groove is displaced toward the central axis of the cylindrical heat exchanger jacket.

Um bei den Trennblechdichtungen eine möglichst gute Dichtwirkung zu erzielen, sollte die äußere Lamelle gegenüber dem Lamellenträger in etwa um 90° abgewinkelt sein. Ausgehend von der bekannten Ausführung der Trennblechdichtung bringt dabei die naheliegende Lösung, die äußere Lamelle gegenüber dem Lamellenträger einfach länger zu gestalten oder eine weitere, längere Lamelle bereitzustellen, um einen größeren Spalt zu überbrücken, Nachteile mit sich. Aufgrund der größeren Schenkellänge der Lamellen verringert sich die Rückstellkraft und damit die Dichtwirkung. Dies wird durch die erfindungsgemäße Konstruktion, bei der der Boden der Aufnahmenut versetzt zur Wärmemitte des Wärmetauschermantels angeordnet ist, vermieden.In order to achieve the best possible sealing effect in the parting plate seals, the outer plate should be angled relative to the plate carrier in about 90 °. On the basis of the known design of the separating plate seal, the obvious solution is to simply make the outer plate longer with respect to the plate carrier or to provide a further, longer plate in order to bridge a larger gap. Disadvantages with it. Due to the larger leg length of the slats, the restoring force and thus the sealing effect are reduced. This is avoided by the construction according to the invention, in which the bottom of the receiving groove is arranged offset to the heat center of the heat exchanger shell.

Die Aufnahmenut des Lamellenträgers wird von einem Boden und zwei Wänden begrenzt. Die Tiefe der Aufnahmenut wird auch als Einschubhöhe für das Längstrennblech des Wärmetauschers bezeichnet. Die Tiefe der Aufnahmenut beträgt vorzugsweise mehr als 10 mm und weniger als 40 mm. Als besonders günstig erweist es sich, wenn die Tiefe der Aufnahmenut zwischen 20 mm und 30 mm liegt.The receiving groove of the disc carrier is limited by a bottom and two walls. The depth of the receiving groove is also referred to as insertion height for the longitudinal dividing plate of the heat exchanger. The depth of the receiving groove is preferably more than 10 mm and less than 40 mm. It proves to be particularly favorable when the depth of the receiving groove is between 20 mm and 30 mm.

Der Abstand, um den der Boden der Aufnahmenut im Verhältnis zur Abwinklung der Lamellen nach innen zur Wärmetauschermitte hin versetzt ist, beträgt vorzugsweise mehr als 20%, insbesondere mehr als 40%, der Tiefe der Aufnahmenut. Unabhängig von der Tiefe der Aufnahmenut erweist es sich als besonders günstig, wenn der Abstand zwischen Boden und Abwinklung mehr als 4 mm, insbesondere mehr als 8 mm, beträgt. Je größer dieser Abstand ist, desto größere Spalte können auch überbrückt werden.The distance by which the bottom of the receiving groove is offset in relation to the angling of the lamellae inwards towards the heat exchanger center is preferably more than 20%, in particular more than 40%, of the depth of the receiving groove. Regardless of the depth of the receiving groove, it proves to be particularly advantageous if the distance between the bottom and angling is more than 4 mm, in particular more than 8 mm. The larger this distance, the larger the gaps can be bridged.

Die erfindungsgemäße Trennblechdichtung überbrückt die großen Spalte zwischen Trennblech und Wärmetauschermantel, ohne dass es zu Dichtproblemen kommt, da durch die erfindungsgemäße Konstruktion die Anpresskraft weitgehend konstant bleibt.The separating plate seal according to the invention bridges the large gaps between the separating plate and the heat exchanger jacket, without resulting in sealing problems, since the contact pressure remains largely constant due to the construction according to the invention.

Neben der U-förmigen Aufnahmenut weist der Lamellenträger Schenkel auf, die vorzugsweise parallel zu den Wänden der Aufnahmenut angeordnet sind. Auf jeder Seite des Lamellenträgers sind Lamellen zwischen den Schenkeln und einer Wand der Aufnahmenut fixiert. Der Lamellenträger weist dabei ein M-förmiges bzw. W-förmiges Profil auf. Zwischen den äußeren Schenkeln des Lamellenträgers und den Wänden der U-förmigen Nut wird eine Art Tasche gebildet, in die Lamellen hineingesteckt werden. Erfindungsgemäß werden sie dabei nicht zur Abwinklung eingeführt, sondern es verbleibt ein Abstand zwischen der Abwinklung und der Tasche. Die Länge des Teils der Lamelle, der in der Tasche fixiert ist, hängt von der Position der Lamelle ab. So weisen die äußeren Lamellen einen kürzeren Bereich auf, der innerhalb der Tasche liegt und die inneren Lamellen weisen vorzugsweise einen längeren Bereich auf, der innerhalb der Tasche angeordnet ist.In addition to the U-shaped receiving groove, the plate carrier has legs, which are preferably arranged parallel to the walls of the receiving groove. On each side of the disk carrier lamellae are fixed between the legs and a wall of the receiving groove. The plate carrier has an M-shaped or W-shaped profile. Between the outer legs of the disc carrier and the walls of the U-shaped groove a kind of pocket is formed, are inserted into the slats. According to the invention they are not introduced for bending, but it remains a distance between the bend and the pocket. The length of the part of the lamella fixed in the pocket depends on the position of the lamella. Thus, the outer sipes have a shorter portion located within the pocket and the inner sipes preferably have a longer portion located within the pocket.

Die Fixierung der Lamellen am Lamellenträger kann auf unterschiedliche Weise erfolgen. Bei einer besonders vorteilhaften Ausführung der Erfindung werden die Lamellen durch Punktverschweißung mit dem Lamellenträger verbunden. Nach dem Einführen der Lamellen in den Lamellenträger wird entlang des Lamellenträgerprofils in bestimmten Abständen, beispielsweise alle 10 cm, eine Punktschweißung vorgenommen.The fixation of the slats on the plate carrier can be done in different ways. In a particularly advantageous embodiment of the invention, the slats are connected by spot welding with the plate carrier. After inserting the lamellae in the plate carrier, a spot weld is made along the plate carrier profile at certain intervals, for example every 10 cm.

Der Lamellenträger kann auf unterschiedliche Weise hergestellt werden. Bei einer Variante wird er aus einem Stück Blech geformt. Das Blech wird dabei so gebogen, dass sich die U-förmige Aufnahmenut ausbildet und die beiden Außenschenkel.The plate carrier can be produced in different ways. In one variant, it is formed from a piece of sheet metal. The sheet is bent so that the U-shaped receiving groove is formed and the two outer legs.

Bei einer anderen Variante der Erfindung wird zur Herstellung des Lamellenträgers zunächst ein separates U-Profil aus einem Blech geformt. An den Außenwänden des U-Profils werden dann Blechstreifen angesetzt und längsverschweißt, so dass ein M-förmiges bzw. W-förmiges Profil entsteht.In another variant of the invention, a separate U-profile is first formed from a sheet metal for the production of the disk carrier. On the outer walls of the U-profile sheet metal strips are then applied and longitudinally welded, so that an M-shaped or W-shaped profile is formed.

Die Lamellen und der Lamellenträger sind mit einer nicht lösbaren Verbindung zu einer Einheit verbunden. Auf jeder Seite des Lamellenträgers, das heißt also oberhalb und unterhalb des Längstrennbleches, sind jeweils mehrere Lamellen in der von den Außenschenkeln und den Wänden des U-Profils gebildeten Tasche fixiert. Vorzugsweise sind auf jeder Seite des Lamellenträgers vier Lamellen in einer Tasche angeordnet. Eine größere Anzahl an Lamellen werden auch als Lamellenpaket bezeichnet, so dass auf jeder Seite des Lamellenträgerprofils jeweils ein Lamellenpaket mit vorzugsweise vier Lamellen angeordnet ist.The slats and the plate carrier are connected to a non-detachable connection to a unit. On each side of the disc carrier, that is Above and below the longitudinal dividing plate, a plurality of fins are respectively fixed in the pocket formed by the outer legs and the walls of the U-profile. Preferably, four fins are arranged in a pocket on each side of the disk carrier. A larger number of slats are also referred to as a plate pack, so that on each side of the plate carrier profile in each case a disc pack is preferably arranged with four fins.

Bei einer Variante der Erfindung schließen die Schenkel des Lamellenträgers bündig mit dem Boden der Aufnahmenut ab. Da erfindungsgemäß der Boden der Aufnahmenut gegenüber der Abwinklung bzw. Abknickung der Lamellen um einen Abstand zur Mitte des Wärmetauschers versetzt angeordnet ist, besteht dieser Abstand auch zwischen den Schenkeln des Lamellenträgers und der Abwinklung.In a variant of the invention, the legs of the disk carrier close flush with the bottom of the receiving groove. Since, according to the invention, the bottom of the receiving groove is offset from the bend or bend of the slats by a distance from the center of the heat exchanger, this distance also exists between the legs of the slat carrier and the bend.

Die Abwinklung unterteilt die Lamellen in zwei Lamellenschenkel. Der äußere Lamellenschenkel liegt mit seiner Stirnseite bzw. Außenkante am Wärmetauschermantel an. Der innere Lamellenschenkel ist erfindungsgemäß nur bereichsweise in der Tasche des Lamellenträgers angeordnet. Bei herkömmlichen Trennblechdichtungen nach dem Stand der Technik ist der innere Lamellenschenkel dagegen vollständig in der Tasche des Lamellenträgers angeordnet.The bend divides the slats into two slats. The outer fin leg rests with its end face or outer edge on the heat exchanger jacket. The inner slat leg is according to the invention only partially arranged in the pocket of the disk carrier. On the other hand, in conventional prior art baffle seals, the inner sipe leg is completely disposed in the pocket of the sipe carrier.

Durch das Hinausragen der Schenkel des Lamellenträgers über den Boden der Aufnahmenut wird der Bereich des inneren Lamellenschenkels, der aus der Tasche hinausragt, zumindest teilweise geführt. Als besonders günstig erweist sich dabei, wenn die Schenkel des Lamellenträgers bis zur Abwinklung der Lamellen ragen. Dadurch wird der gesamte Bereich des inneren Lamellenschenkels, der aus der Tasche herausragt, von dem Schenkel des Lamellenträgers geführt.By protruding the legs of the disk carrier over the bottom of the receiving groove, the region of the inner disk leg, which protrudes from the pocket, at least partially performed. In this case, it proves to be particularly favorable if the limbs of the disk carrier project up to the angling of the disks. As a result, the entire region of the inner lamellar limb, which projects out of the pocket, is guided by the limb of the lamellar support.

Bei dieser Variante der Erfindung ist der Boden der Aufnahmenut nicht nur gegenüber der Abknickung der Lamellen nach innen versetzt, sondern auch gegenüber der äußeren Abschlusskante des Lamellenträgerschenkels. Die über den Boden der Aufnahmenut hinausragenden Schenkel des Lamellenträgers geben den Bereich des inneren Lamellenschenkels, der nicht in der Tasche geführt wird, zusätzlichen Halt und verhindern ein Abknicken. Durch die äußeren Schenkel des Lamellenträgers werden die Lamellen gestützt. Ragen die Schenkel des Lamellenträgers bis zur Abwinklung der Lamellen, so wird der gesamte Bereich der inneren Lamellenschenkel gestützt.In this variant of the invention, the bottom of the receiving groove is offset not only with respect to the bending of the slats inwards, but also with respect to the outer end edge of the slat support leg. The protruding beyond the bottom of the receiving groove legs of the disc carrier give the area of the inner disc leg, which is not performed in the bag, additional support and prevent kinking. The lamellae are supported by the outer legs of the plate carrier. If the legs of the plate carrier protrude until the plates are bent, the entire area of the inner plate legs is supported.

Schließen die Schenkel des Lamellenträgers bündig mit dem Boden der Aufnahmenut ab, so übernimmt auch der innere Lamellenschenkel eine federnde Wirkung. Nicht nur der radial äußere Lamellenschenkel, dessen Stirnseite bzw. Außenkante am Wärmetauschermantel anliegt, wirkt federnd, sondern der Bereich des inneren Lamellenschenkels, der nicht in der Tasche angeordnet ist, hat eine Federwirkung. Bei dieser Variante, bei der die äußeren Schenkel des Lamellenträgers bündig mit dem Boden der Aufnahmenut abschließen, weist die Trennblechdichtung somit zwei Federkonstanten auf.If the legs of the disk carrier are flush with the bottom of the receiving groove, the inner disk leg also takes on a resilient action. Not only the radially outer slat limb, the front side or outer edge of which rests on the heat exchanger jacket, acts resiliently, but the region of the inner slat limb, which is not arranged in the pocket, has a spring action. In this variant, in which the outer limbs of the plate carrier terminate flush with the bottom of the receiving groove, the separating plate seal thus has two spring constants.

Fig. 1 zeigt einen Ausschnitt einer radialen Schnittdarstellung durch einen Wärmetauschermantel 1. Der zylindrische Wärmetauschermantel 1 ist Teil eines Wärmetauschers, der an seinen beiden Stirnseiten mit entsprechenden Böden versehen ist. In dem Wärmetauscher sind in Fig. 1 nicht dargestellte Rohre angeordnet. Weiterhin ist in dem Wärmetauscher ein Trennblech 2 angeordnet. Das Trennblech 2 unterteilt den Wärmetauscher räumlich. Es bildet eine Barriere für die durch den Wärmetauscher geführten Fluide. Bei den Fluiden kann es sich um Flüssigkeiten und/oder Gase handeln. Fig. 1 shows a section of a radial sectional view through a heat exchanger shell 1. The cylindrical heat exchanger shell 1 is part of a heat exchanger, which is provided at its two end faces with corresponding bottoms. In the heat exchanger are in Fig. 1 arranged pipes not shown. Furthermore, a separating plate 2 is arranged in the heat exchanger. The separating plate 2 divides the heat exchanger spatially. It forms a barrier to the fluids passing through the heat exchanger. The fluids may be liquids and / or gases.

Zwischen dem Trennblech 2 und dem Wärmetauschermantel besteht ein Spalt f. Der Spalt f wird von einer Trennblechdichtung 3 abgedichtet. Die Trennblechdichtung 3 umfasst Lamellen 4, die in einem Lamellenträger 5 angeordnet sind. Bei der Trennblechdichtung 3 handelt es sich um eine Ganzmetalldichtung. Die Lamellen 4 werden aus Blechstreifen gebildet. Diese Blechstreifen werden gebogen, so dass die Lamellen 4 eine Abwinklung 6 aufweisen. Die Abwinklung 6 ermöglicht eine federnde Anlage der Lamellen 4 am Wärmetauschermantel 1.There is a gap f between the separating plate 2 and the heat exchanger jacket. The gap f is sealed by a baffle seal 3. The partition plate seal 3 comprises lamellae 4, which are arranged in a plate carrier 5. The separating plate seal 3 is an all-metal seal. The slats 4 are formed from sheet metal strips. These metal strips are bent, so that the lamellae 4 have an angled portion 6. The bend 6 allows a resilient contact of the slats 4 on the heat exchanger jacket. 1

Der Lamellenträger 5 umfasst eine U-förmige Aufnahmenut 7 in der das Trennblech 2 entlang seiner Längsseite angeordnet ist. Zur Befestigung der Trennblechdichtung 3 sind keinerlei Schrauben erforderlich. Es entfallen deshalb bei der Montage auch das Bohren von Löchern sowie alle üblichen Verschraubungsarbeiten. Bei der Montage wird die Trennblechdichtung 3 mit ihrer Aufnahmenut 7 auf die Längsseite des Trennbleches 2 geschoben.The plate carrier 5 comprises a U-shaped receiving groove 7 in which the separating plate 2 is arranged along its longitudinal side. For fixing the partition seal 3 no screws are required. It therefore accounts for the mounting and drilling holes as well as all the usual Verschraubungsarbeiten. During assembly, the separating plate seal 3 is pushed with its receiving groove 7 on the longitudinal side of the separating plate 2.

Der Lamellenträger 5 weist Schenkel 8 auf. Bei der Ausführung gemäß Fig. 1 wird der Lamellenträger 5 aus einem Blechstreifen so gebogen, dass sich ein M-förmiges Profil ergibt, welches in der Mitte eine Aufnahmenut 7 aufweist. Die Aufnahmenut 7 wird von zwei einander gegenüberliegenden Seitenwänden 9 und einem Boden 10 gebildet. An den Seitenwänden 9 sind jeweils die Schenkel 8 des Lamellenträgers 5 angeformt. Zwischen den Schenkeln 8 und den Seitenwänden 9 bildet der Lamellenträger 5 auf jeder Seite der Aufnahmenut 7 jeweils eine Tasche, in welcher die Lamellen 4 angeordnet sind. Das in dieser Tasche angeordnete Lamellenpaket wird durch Punktschweißung entlang des Lamellenträgers 5 am Lamellenträger fixiert. Erfindungsgemäß ist der Boden 10 der Aufnahmenut 7 gegenüber der Abwinklung 6 um einen Abstand zur Mitte des Wärmetauschermantels 1 hin versetzt angeordnet. Somit ist der Boden 10 der Aufnahmenut 7 gegenüber der Abwinklung 6 der Lamellen 4 radial nach innen verschoben.The disk carrier 5 has leg 8. In the execution according to Fig. 1 the plate carrier 5 is bent from a metal strip so that an M-shaped profile results, which has a receiving groove 7 in the middle. The Receiving groove 7 is formed by two opposite side walls 9 and a bottom 10. On the side walls 9 each of the legs 8 of the disk carrier 5 are formed. Between the legs 8 and the side walls 9 of the plate carrier 5 forms on each side of the receiving groove 7 each have a pocket in which the slats 4 are arranged. The disk pack arranged in this pocket is fixed by spot welding along the disk carrier 5 on the disk carrier. According to the invention, the bottom 10 of the receiving groove 7 is offset from the bend 6 by a distance from the center of the heat exchanger jacket 1. Thus, the bottom 10 of the receiving groove 7 relative to the bend 6 of the slats 4 is displaced radially inwards.

Durch diese erfindungsgemäße Konstruktion kann ein größerer Spalt f abgedichtet werden, ohne dass die Anpresskraft der Lamellen 4 am Wärmetauschermantel 1 abnimmt.By means of this construction according to the invention, a larger gap f can be sealed, without the contact force of the lamellae 4 on the heat exchanger jacket 1 decreasing.

Die Tiefe der Aufnahmenut 7 beträgt im Ausführungsbeispiel gemäß Fig. 1 20 mm. Der Abstand S, um den der Boden 10 der Aufnahmenut 7 gegenüber der Abwinklung 6 der Lamellen 4 zur Mitte des Wärmetauschermantels 1 hin versetzt angeordnet ist, beträgt im Ausführungsbeispiel mehr als 20 % der Tiefe der Aufnahmenut 7 und somit mehr als 4 mm.The depth of the receiving groove 7 is in the embodiment according to Fig. 1 20 mm. The distance S, by which the bottom 10 of the receiving groove 7 is offset relative to the bend 6 of the slats 4 toward the center of the heat exchanger jacket 1, is more than 20% of the depth of the receiving groove 7 and thus more than 4 mm in the exemplary embodiment.

Bei dem Ausführungsbeispiel gemäß Fig. 1 schließen die Schenkel 8 des Lamellenträgers 5 bündig mit dem Boden 10 der Aufnahmenut 7 ab. Die Abwinklung 6 unterteilt die Lamellen 4 in einen äußeren Lamellenschenkel 11 und einen inneren Lamellenschenkel 12. Der radial äußere Lamellenschenkel 11 liegt mit seiner Stirnseite am Wärmetauschermantel 1 an. Der innere Lamellenschenkel 12 ist nur zum Teil in der Tasche des Lamellenträgers 5 angeordnet. Der andere Teil ragt aus der Tasche des Lamellenträgers 5 heraus. Die Breite des herausragenden Teils des inneren Lamellenschenkels 12 entspricht dem Abstand S. Dieser Teil des inneren Lamellenschenkels 12 wird nicht geführt und kann somit auch eine federnde Funktion übernehmen.In the embodiment according to Fig. 1 close the legs 8 of the disk carrier 5 flush with the bottom 10 of the receiving groove 7 from. The bend 6 subdivides the lamellae 4 into an outer lamellar limb 11 and an inner lamellar limb 12. The radially outer lamellar limb 11 lies with its end face against the heat exchanger jacket 1. The inner plate leg 12 is only partially arranged in the pocket of the plate carrier 5. The other part protrudes from the pocket of the disc carrier 5 out. The width the protruding part of the inner slat leg 12 corresponds to the distance S. This part of the inner slat leg 12 is not guided and can thus also assume a resilient function.

Fig. 2 zeigt eine Variante, bei der die Schenkel 8 des Lamellenträgers 5 über den Boden 10 der Aufnahmenut 7 hinausragen. Sie erstrecken sich in radialer Richtung nach außen zum Wärmetauschermantel 1 hin. Die Schenkel 8 ragen bis zur Abwinklung 6 der Lamellen 4. Da der Boden 10 der Aufnahmenut 7 gegenüber der Abwinklung 6 der Lamellen 4 radial nach innen versetzt angeordnet ist, weisen die inneren Lamellenschenkel 12 einen Bereich auf, der in der Tasche des Lamellenträgers angeordnet ist und einen Bereich, der aus der Tasche herausragt. Dieser Bereich wird jedoch im Gegensatz zu dem zuvor beschriebenen Ausführungsbeispiel von den Schenkeln 8 des Lamellenträgers geführt. Dadurch wird ein unerwünschtes Abknicken vermieden. Weiterhin führt diese Konstruktion zu einer insgesamt weniger elastischen und weniger federnden Wirkung, die sich jedoch durch eine größere Stabilisierung der Lamellen 4 auszeichnet. Fig. 2 shows a variant in which the legs 8 of the plate carrier 5 project beyond the bottom 10 of the receiving groove 7. They extend in the radial direction outward to the heat exchanger jacket 1 out. Since the bottom 10 of the receiving groove 7 is offset radially inwardly relative to the angled section 6 of the lamellae 4, the inner lamellae legs 12 have a region which is arranged in the pocket of the lamella carrier and an area that sticks out of the pocket. However, in contrast to the exemplary embodiment described above, this region is guided by the legs 8 of the disk carrier. This avoids unwanted kinking. Furthermore, this construction leads to an overall less elastic and less resilient effect, which is characterized by a greater stabilization of the slats 4.

Fig. 3 zeigt eine Trennblechdichtung 3, bei welcher der Lamellenträger aus einem U-förmigen Profil gefertigt wird, an das zwei Blechstreifen angeschweißt werden. Dabei wird eine Längsschweißung vorgenommen. Die Blechstreifen bilden die Schenkel des Lamellenträgers 5. Fig. 3 shows a baffle seal 3, wherein the plate carrier is made of a U-shaped profile to which two metal strips are welded. In this case, a longitudinal weld is made. The metal strips form the legs of the plate carrier. 5
