- the sealing element 130 is a circumferential (ie annular) sealing element, wherein the sealing element 130 has no circular shape, but approximately a rectangular shape with rounded corners, which will be explained in more detail in the following description.
- the sealing element 130 is inserted into the receiving grooves 120 and has a portion 140 which extend at one end of the bottom member 110 between the receiving grooves 120 on a surface of the bottom member 110.

- the approach presented above offers the possibility of using a unitary floor element 110, for example as a piece, for the production of different heat exchangers 100, without requiring a specific shape of a circumferential groove around all sides of the floor element 110. Rather, the bottom element can be cut in accordance with the variant of the heat exchanger to be produced, wherein at least one additional opening of the bottom element should not be occupied on each end face with pipes, as in these additional openings, the side part is inserted. Furthermore, for the different variants of Heat exchanger different cover elements are used, which are made for example of low-priced plastic material or include this.

- the method 600 includes a step of placing the blanket member 630 on the sealing member such that the sealing member is between the bottom member and the side protrusions of the cover member between the receiving grooves and the side protrusions extend along the receiving grooves extend into it.
- the placement of the cover element on the sealing element can also be carried out such that an edge of the cover element presses on a portion of the sealing element, which is arranged on a surface of the bottom element outside of the receiving grooves.

Description
Die vorliegende Erfindung bezieht sich auf einen Wärmetauscher und ein Verfahren zur Herstellung eines Wärmetauschers gemäß den selbständigen Ansprüchen.The present invention relates to a heat exchanger and a method of manufacturing a heat exchanger according to the independent claims.
Die Verbindung eines Kühlmittelkastens mit einem Rohrboden mit Rohröffnungen bzw. Durchzügen eines Wärmetauschers erfordert eine zuverlässige Dichtung zwischen den beiden genannten Elementen, wie Kasten und Boden, um ein Austreten des Kühlmittels und somit einen eventuellen Ausfall des Wärmetauschers oder des zu kühlenden Aggregates zu verhindern. Die
Um eine solche umlaufende Nut in den Rohrboden einbringen zu können ist ein Stanzwerkzeug für eine Boden-, und Seitenteilgröße bzw. ein aufwendiges Familienwerkzeug erforderlich, insbesondere wenn die Rohrböden für mehrere unterschiedliche Wärmetauscher mit verschiedenen Abmessungen, d.h. in verschiedene Längen, gefertigt werden sollen. Eine umlaufende Bodenrinne beim Boden lässt bisher kein voll flexibles Fertigungskonzept zu. Bisher muss vielmehr für jeden Rohrboden ein eigenes Stanzwerkzeug bzw. ein Familienwerkzeug erstellt werden, welches aufwendig auf eine begrenzte Anzahl weiterer Längen umgebaut werden muss. Es wird ferner für jede Boden-, und Seitenteillänge ein Bandmaterial benötigt. Die bedeutet eine fertigungstechnisch aufwendige Herstellung der umlaufenden Bodenrinne, mit einem fertigungsbedingter Mindestabstand vom Seitenteil bzw. Rohr zur Bodenrinne. Es ist somit ein Abstand zwischen dem ersten und letzten Rohr (bzw. Seitenteil) zur Bodenrinne vorzusehen.In order to be able to introduce such a circumferential groove in the tubesheet, a punching tool for a bottom and side part size or a complex family tool is required, in particular if the tube plates for several different heat exchangers with different dimensions, i. in different lengths, to be made. A circumferential gutter at the bottom does not allow for a fully flexible manufacturing concept. So far, rather, a separate punching tool or a family tool must be created for each tubesheet, which must be rebuilt consuming a limited number of other lengths. It is also required for each floor, and Seitenteillänge a strip material. This means a manufacturing technically complex production of the circumferential gutter, with a production-related minimum distance from the side panel or pipe to the gutter. It is thus a distance between the first and last pipe (or side part) provided to the gutter.
Ein Wärmetauscher gemäß dem Oberbegriff des Anspruchs 1 ist aus der

- einem Deckelelement, das Seitenvorsprünge an zwei sich gegenüberliegenden Seiten aufweist, wobei sich die Seitenvorsprünge entlang der Aufnahmenuten in die Aufnahmenuten hinein erstrecken; die Seitenvorsprünge verlaufen längs des Deckels, und
- einem umlaufenden Dichtelement, das zwischen dem Bodenelement und den Seitenvorsprüngen des Deckelelements in den beiden Aufnahmenuten und zwischen den beiden längs verlaufenden Aufnahmenuten und senkrecht dazu (d.h. außerhalb der Aufnahmenuten) auf einer Oberfläche des Bodenelementes angeordnet ist.

Die vorliegende Erfindung bietet den Vorteil, dass eine deutlich einfachere Herstellungsmöglichkeit zur Herstellung von Wärmetauschern mit unterschiedlichen Abmessungen gegeben ist. Insbesondere kann vermieden werden, dass für die unterschiedlichen Wärmetauscher jeweils separate Fertigungswerkzeuge oder schwierig umzustellende Werkzeugfamilien vorgesehen werden müssen. Auf diese Weise lässt sich auch durch die Vermeidung von Rüstzeiten bei der Umstellung der Fertigungswerkzeuge eine Verringerung der Herstellungszeit für einen solchen Wärmetauscher und somit eine Verringerung der Herstellungskosten für einen solchen Wärmetauscher realisieren.The present invention offers the advantage that a much simpler manufacturing option for the production of heat exchangers with different dimensions is given. In particular, it can be avoided that separate production tools or tool families that are difficult to change have to be provided for the different heat exchangers. In this way, can be realized by avoiding set-up times in the conversion of production tools, a reduction in the production time for such a heat exchanger and thus a reduction in the production cost of such a heat exchanger.
Günstig ist es, wenn die Aufnahmenuten des Bodenelements an zwei sich gegenüberliegenden Hauptseiten angeordnet sind. Unter einer Haupt- oder Langseite kann dabei eine Seite des Bodenelements verstanden werden, die länger als eine andere Seite des Bodenelements ist. Eine derartige Ausführungsform der vorliegenden Erfindung bietet den Vorteil, dass das Dichtelement über einen möglichst großen Bereich präzise gehalten und fixiert wird und somit eine hohe Dichtheit zwischen dem Deckelelement und dem Bodenelement erreicht wird.It is advantageous if the receiving grooves of the bottom element are arranged on two opposite main sides. In this case, a main or long side can be understood to mean one side of the floor element that is longer than another side of the floor element. Such an embodiment of the present invention has the advantage that the sealing element is held and fixed precisely over as large a range as possible and thus a high degree of tightness is achieved between the cover element and the base element.
Gemäß einer weiteren Ausführungsform der vorliegenden Erfindung kann das Bodenelement eine Mehrzahl von Öffnungen aufweisen, die zur Durchführung von Kühlungsleitungen ausgebildet sind, wobei ferner zumindest eine Seitenwand des Wärmetauschers vorgesehen ist, die sich durch eine der Öffnungen des Bodenelementes hindurch erstreckt. Eine derartige Ausführungsform der vorliegenden Erfindung bietet den Vorteil, dass eine Seitenwand des Wärmetauschers konstruktiv sehr einfach an dem Wärmetauscher befestigt werden kann. Ferner ist auch eine feinstufige Festlegung einer Gesamtlänge des Wärmetauschers möglich, insbesondere wenn die Öffnungen im Bodenelement sehr nahe beieinander liegen.According to a further embodiment of the present invention, the bottom element may have a plurality of openings, which are designed for the passage of cooling lines, wherein at least one side wall of the heat exchanger is provided, which extends through one of the openings of the bottom element. Such an embodiment of the present invention offers the advantage that a side wall of the heat exchanger structurally very easy to be attached to the heat exchanger. Furthermore, a finely graded determination of an overall length of the heat exchanger is possible, especially if the openings in the bottom element are very close to each other.
An Vorteil ist es auch, wenn gemäß einer Ausführungsform der vorliegenden Erfindung die Seitenwand eine Bördelung aufweist, um das Deckelelement zu hintergreifen und das Deckelelement zusammen mit dem Dichtelement an eine Oberfläche des Bodenelementes zu drücken. Eine derartige Ausführungsform der vorliegenden Erfindung bietet eine sehr einfache Möglichkeit zur Verbindung und Fixierung des Deckelelements an dem Bodenelement, ohne dass aufwändige Herstellungsschritte wie beispielsweise ein Verschweißen von einzelnen Elementen des Wärmetauschers erforderlich sind.It is also advantageous if, according to one embodiment of the present invention, the side wall has a flange to engage behind the lid member and to press the lid member together with the sealing element to a surface of the bottom element. Such an embodiment of the present invention provides a very simple way of connecting and fixing the lid member to the floor member without requiring elaborate manufacturing steps such as welding individual members of the heat exchanger.

Eine derartige Ausführungsform der vorliegenden Erfindung bietet den Vorteil einer schnellen und einfachen Herstellung eines solchen Wärmetauschers, da die Seitenwand einen seitlichen Abschluss an den Schnittkanten des Bodenelements bietet.In order to provide a structurally very simple to produce heat exchanger, wherein the side wall forms a conclusion on a narrow side of the bottom member, the side wall with respect to the receiving grooves may be arranged at an angle, in particular, the side wall may be arranged at a right angle to the receiving grooves. Such an embodiment of the present invention offers the advantage of a quick and easy manufacture of such a heat exchanger, since the side wall provides a lateral termination at the cut edges of the bottom element.
Eine besonders effizient herzustellen Ausführungsform der vorliegenden Erfindung kann dann realisiert werden, wenn ferner eine der Seitenwand gegenüberliegende zweite Seitenwand des Wärmetauschers vorgesehen ist, die sich durch eine andere der Öffnungen des Bodenelementes hindurch erstreckt. Auf diese Weise lässt sich das vorstehend bereits näher beschriebene Konzept in der Massenfertigung effizient einsetzen, da ein solcher Wärmetauscher an den beiden (schmalen) Seiten durch eine solche den Öffnungen des Bodenelements hindurch gesteckte Seitenwand begrenzt wird.An especially efficient embodiment of the present invention can be realized when further comprising a second side wall of the heat exchanger opposite the side wall extending through another of the openings of the bottom member. In this way, the concept described above in mass production can be used efficiently, since such a heat exchanger on the two (narrow) sides is limited by such a side wall inserted through the openings of the bottom element.
Gemäß einer anderen Ausführungsform der vorliegenden Erfindung kann das Deckelelement aus einem Material herstellt sein, das Kunststoff umfasst, insbesondere wobei das Deckelelement vollständig aus Kunststoff hergestellt ist. Eine derartige Ausführungsform der vorliegenden Erfindung bietet den Vorteil, dass ein Deckelelement verwendbar ist, dass einerseits aus einem kostengünstigen Material hergestellt sein kann, und andererseits ein zusätzlicher Herstellungsschritt wie beispielsweise das separate Verschweißen des Deckelelements mit dem Bodenelement vermieden werden kann, wodurch sich die Herstellungskosten für einen solchen Wärmetauscher weiter reduzieren lassen.According to another embodiment of the present invention, the lid member may be made of a material comprising plastic, in particular wherein the lid member is made entirely of plastic. Such an embodiment of the present invention offers the advantage that a cover element can be used which on the one hand can be made of a low-cost material, and on the other hand an additional manufacturing step such as the separate welding of the cover element to the bottom element can be avoided, thereby reducing the manufacturing costs for can further reduce such a heat exchanger.
Gemäß einer weiteren Ausführungsform der vorliegenden Erfindung kann auch zumindest eine Leitung zur Führung eines Temperierungsmediums durch eine Öffnung des Bodenelementes geführt sein, um einen Raum zwischen dem Bodenelement und dem Deckelelement fluidisch zu kontaktieren, insbesondere wobei mehrere Leitungen zur Führung des Temperierungsmediums durch unterschiedliche Öffnungen des Bodenelementes geführt sind. Eine derartige Ausführungsform der vorliegenden Erfindung bietet den Vorteil auf, dass ein Wärmetauscher mit einer hohen Wärmetauschoberfläche geschaffen werden kann, so dass eine effiziente Wärmeübertragung in Bezug auf einen vorhandenen Bauraum ermöglicht wird.According to a further embodiment of the present invention, at least one conduit for guiding a Temperierungsmediums can be passed through an opening of the bottom element to fluidly contact a space between the bottom element and the lid member, in particular wherein a plurality of lines for guiding the Temperierungsmediums through different openings of the bottom element are guided.

Um eine besonders sichere Verbindung zwischen dem Deckelelement und dem Bodenelement insbesondere auch in der oder den Aufnahmenut(en) zu schaffen, kann gemäß einer weiteren vorteilhaften Ausführungsform der vorliegenden Erfindung zumindest eine Aufnahmenut einen Rand aufweisen, der zumindest teilweise umgebogen ist, um einen Teil eines der Seitenvorsprünge zu hintergreifen und hierdurch das Deckelelement zusammen mit dem Dichtelement in die Aufnahmenut des Bodenelementes zu drücken. Dies bedeutet, dass beispielsweise der Seitenvorsprung in einer Aufnahmenut oder die Seitenvorsprünge in den Aufnahmenuten durch eine Fixierung gehalten wird, die beispielsweise in einem Burgzinnen-Bördelungsverfahren oder in einem Wellschlitzverfahren ausgeführt sein kann. Auf diese Weise kann eine sichere und technisch einfach herzustellende Verbindung zwischen dem Deckelelement, dem Dichtelement und dem Bodenelement realisiert werden.In order to provide a particularly secure connection between the cover element and the bottom element in particular in the or the receiving groove (s), according to a further advantageous embodiment of the present invention, at least one receiving groove having an edge which is at least partially bent to a part of a to engage behind the side projections and thereby to press the lid member together with the sealing element in the receiving groove of the bottom element.

In der nachfolgenden Beschreibung der bevorzugten Ausführungsbeispiele der vorliegenden Erfindung werden für die in den verschiedenen Zeichnungen dargestellten und ähnlich wirkenden Elemente gleiche oder ähnliche Bezugszeichen verwendet, wobei auf eine wiederholte Beschreibung dieser Elemente verzichtet wird.In the following description of the preferred embodiments of the present invention, the same or similar reference numerals are used for the elements shown in the various drawings and similar, and a repeated description of these elements will be omitted.
Der vorstehend vorgestellte Ansatz bietet nun die Möglichkeit, ein einheitliches Bodenelement 110, beispielsweise als Meterware, zur Herstellung von unterschiedlichen Wärmetauschern 100 zu verwenden, ohne dass eine bestimmte Form einer umlaufenden Nut um alle Seiten des Bodenelements 110 erforderlich ist. Vielmehr kann das Bodenelement entsprechend der herzustellenden Variante des Wärmetauschers zurecht geschnitten werden, wobei zumindest eine zusätzliche Öffnung des Bodenelements auf jeder Stirnseite nicht mit Rohrleitungen besetzt sein sollte, da in diese zusätzlichen Öffnungen das Seitenteil eingefügt wird. Ferner können für die unterschiedlichen Varianten der Wärmetauscher unterschiedliche Deckelelemente verwendet werden, die beispielsweise aus preisgünstigem Kunststoffmaterial hergestellt sind oder dieses umfassen. Dabei kann durch die Verwendung des Dichtelements, welches einen Teilbereich aufweist, der über eine Oberfläche des Bodenelements geführt ist dennoch sichergestellt werden, dass eine fluiddichte Verbindung zwischen dem Deckelelement 150 und dem Bodenelement 110 ausgebildet wird. Auf einen aufwändigen Verfahrensschritt des Verschweißens des Deckelelements 150 mit dem Bodenelement 110 kann somit verzichtet werden, wodurch sich der hier vorgestellten Ansatz weiter kostensenken ausweist. Die beiden parallel an gegenüberliegenden Langseiten des Bodenelements 110 verlaufenden Aufnahmenuten 120 sind somit an den Stirnseiten offen, an denen das oder die Seitenteile 170 angeordnet werden. Dies ist jedoch nicht weiter problematisch, da durch den Abschnitt 140 des Dichtelements 130, der zwischen den gegenüberliegenden Aufnahmenuten 120 des Bodenelements über die Oberfläche des Bodenelements 110 verläuft, dennoch eine zuverlässige Abdichtung des Innenbereichs des Deckelelements 150 gegenüber dem Seitenteil 170 gewährleistet ist.The approach presented above now offers the possibility of using a
Durch den hier vorgestellten Ansatz lässt sich eine Einsparung hoher Werkzeugkosten realisieren, da mit einem Stanzwerkzeug flexibel jede beliebige Bodenlänge hergestellt werden kann. Serienteile, Prototypen und Ersatzteile können mit demselben Serienwerkzeug hergestellt werden. Hierdurch kann ferner. Leistungssteigerung bei gleichem Bauraum erreicht werden, da durch Verbinden des Deckelelementes mit dem Bodenelement durch das Umbiegen der Ränder der Aufnahmenuten und/oder der Teilbereiche der Seitenteile eine gegen Materialermüdung anfällige stoffschlüssige Verbindung des Deckelelementes mit dem Bodenelement vermieden werden kann. Eine Rohrleitung kann somit sehr nahe an dem Dichtelement und der Bördelung zwischen dem Deckelelement und dem Bodenelement angeordnet werden, was im Stand der Technik einen bestimmten Mindestabstand zwischen der äußerten Rohleitung und der Verbindung zwischen dem Bodenelement und dem Deckelbereich zur Vermeidung einer zu hohen thermischen Belastung der Verbindungsnaht zwischen dem Bodenelement und dem Deckelement erfordern würde. Hierdurchlässt sich die vorstehend genannte Leistungssteigerung auf vorgegebenem Bauraum realisieren. Ferner bietet auch die Verwendung des hier vorgeschlagenen Konzeptes eine Möglichkeit zur Einsparung von Logistikkosten durch vereinfachte Lagerhaltung (je eine Bandbreite für alle Boden-, und Seitenteillänge), Rüstkostenreduzierung (OTED) dadurch die Fertigung kleinerer Losgrößen (wirtschaftlichere Lagerbestände).The approach presented here makes it possible to realize a saving in high tool costs since any desired floor length can be produced flexibly with a punching tool. Series parts, prototypes and spare parts can be produced with the same standard tool. This can further. Increased performance can be achieved with the same space, since by bonding the lid member to the bottom element by bending the edges of the grooves and / or the portions of the side panels a susceptible to fatigue material connection of the cover element can be avoided with the bottom element. A pipeline can thus be arranged very close to the sealing element and the flange between the cover element and the bottom element, which in the prior art, a certain minimum distance between the expressed Rohleitung and the connection between the bottom element and the lid area to avoid excessive thermal load Would require connecting seam between the bottom element and the cover element. This makes it possible to realize the aforementioned performance increase in a given space. Furthermore, the use of the concept proposed here also offers a possibility for saving on logistics costs by simplifying storage (one bandwidth for each floor and side length), reducing set-up costs (OTED) thereby the production of smaller lot sizes (more economical stocks).
Für jede Variante des herzustellenden Wärmetauschers braucht daher nur ein flexibles Bodenstanzwerkzeug gebaut werden, wodurch Werkzeugkosten und Fertigungskosten in der Serie, Ersatz sowie auch in dem Prototypenbau gespart werden können. Zugleich kann eine Erhöhung der Netzbreite bei gleicher Bodenlänge realisiert werden.For each variant of the heat exchanger to be produced, therefore, only a flexible bottom punch tool needs to be built, which saves tooling costs and production costs in the series, replacement and also in prototype construction. At the same time, an increase in the network width can be realized with the same floor length.
Den Boden und Seitenteil kann somit mit einem vollflexiblen Stanzwerkzeug ohne umlaufende Bodenrinne hergestellt werden, und der Wasserkasten stirnseitig mit einem durch den ersten und letzten Rohrschlitz gestecktes Seitenteil verschlossen werden. Dadurch kann trotz fehlender Stirnseite am Boden(d.h. Bodenelement) umlaufend Druck auf die Dichtung ausgeübt werden.The bottom and side panel can thus be made with a fully flexible punching tool without circumferential gutter, and the water tank are closed at the front end with an inserted through the first and last tube slot side panel. As a result, pressure can be exerted on the seal in spite of the absence of the end face on the floor (that is, the floor element).
Der hier vorgestellte Ansatz ermöglicht somit die folgenden Vorteile:
- Reduzierung von Kosten für Boden-, und Seitenteilwerkzeuge
- Reduzierung von Aufwendungen für Prototypen und Ersatzteile (Aftersales), es sind keine weiteren Werkzeuge erforderlich
- Reduzierung von Rüstkosten (OTED)
- Reduzierung von Lager-, und Bestandskosten durch Fertigung kleinerer Losgrößen
- Reduzierung von Lager-, und Bestandskosten für Bandmaterial (ein Bandmaterial ersetzt mehrere SNR).
- Höhere Kühlleistung bei gleichem Bauraum.
- Reduction of costs for floor and side part tools
- Reduction of expenses for prototypes and spare parts (aftersales), no further tools are required
- Reduction of setup costs (OTED)
- Reduction of inventory and inventory costs by manufacturing smaller batch sizes
- Reduction of stock and inventory costs for strip material (one strip material replaces several SNRs).
- Higher cooling capacity with the same installation space.
Auf die vorstellte Weise lässt sich eine längenvariable Boden-, Seitenteilherstellung (längs- bzw. quergestanzt) und ein Dichtungskonzept bei Schließböden sowie eine gleichzeitige Leistungssteigerung bei gleicher Bauraumgröße umsetzen.In the manner presented can be a variable-length floor, side part production (longitudinal or cross-punched) and a sealing concept in closing floors and a simultaneous increase in performance with the same space size implement.
