Kühlmittelkühler können mehrere Rohre aufweisen, welche von einem Medium durchströmt werden können und gleichzeitig von einem Medium umströmt werden können. In einer bekannten Bauform sind die Rohre endseitig in Rohrböden aufgenommen. Die Rohrböden weisen eine der Anzahl der Rohre entsprechende Anzahl von Öffnungen auf, wobei jeweils ein Rohr in eine Öffnung eingesteckt ist. Der Rohrboden wird durch einen kastenartigen Deckel zu einem Sammelkasten abgeschlossen. Hierzu wird der kastenartige Deckel in den Rohrboden eingesetzt und wird mit diesem verbunden.Coolant cooler can have a plurality of tubes, which can be flowed through by a medium and at the same time can be flowed around by a medium. In a known design, the tubes are added end in tube sheets. The tubesheets have a number of openings corresponding to the number of tubes, one tube each being inserted into an opening.

Nachteilig an den Vorrichtungen im Stand der Technik ist insbesondere, dass die bekannten Rohrböden nur schlecht an unterschiedlich breite Öffnungen bei ansonsten geleichbleibender Breite des Rohrbodens angepasst werden können. Es ist daher ein erhöhter Anpassungsaufwand erforderlich, um Rohrböden gleicher Breite mit unterschiedlich breiten Öffnungen bereitzustellen. Insbesondere der Aufnahmebereich der Rohrböden, in welche der kastenartige Deckel eingesetzt wird muss zur Erreichung einer ausreichend hohen Dichtigkeit besonders angepasst werden. Daher werden für unterschiedlich breite Öffnungen unterschiedlich breite Rohrböden verwendet, wodurch auch die Abmessungen der gebildeten Wärmeübertrager variieren. Dies bedingt einen höheren Montageaufwand, welcher sich nachteilig auf die Montagezeit und die Kosten auswirkt.A disadvantage of the devices in the prior art is in particular that the known tube sheets can be adapted only to different widths wide openings otherwise constant width of the tube sheet. It is therefore an increased adaptation effort required to provide tube plates of equal width with different width openings. In particular, the receiving area of the tube sheets, in which the box-like lid is used must be particularly adapted to achieve a sufficiently high density. Therefore, differently wide tube sheets are used for different widths of openings, whereby the dimensions of the heat exchanger formed vary. This requires a higher installation effort, which adversely affects the assembly time and costs.
Daher ist es die Aufgabe der vorliegenden Erfindung einen Rohrboden zu schaffen, der bei gleichbleibender Breite des Rohrbodens an unterschiedlich breite Öffnungen im Rohrboden angepasst werden kann. Weiterhin ist es die Aufgabe der vorliegenden Erfindung einen Wärmeübertrager mit einem solchen Rohrboden zu schaffen.Therefore, it is the object of the present invention to provide a tube sheet, which can be adapted to different widths openings in the tube sheet with the same width of the tube sheet. Furthermore, it is the object of the present invention to provide a heat exchanger with such a tube sheet.
Die Aufgabe hinsichtlich des Rohrbodens wird durch einen Rohrboden mit den Merkmalen von Anspruch 1 gelöst.The task with respect to the tube sheet is achieved by a tube sheet having the features of
Ein Ausführungsbeispiel der Erfindung betrifft einen Rohrboden für einen Wärmeübertrager, mit einem langlochartige Öffnungen aufweisenden Bodenbereich, wobei die langlochartigen Öffnungen von Durchzügen umrandet sind und der Rohrboden einen aufgestellten Randbereich aufweist, wobei zwischen den Durchzügen und dem aufgestellten Randbereich eine U-förmige Rinne als Aufnahmebereich für den Fuß eines kastenartigen Deckels ausgebildet ist, wobei die U-förmige Rinne durch eine innenliegende erste Wandung, den aufgestellten Randbereich und eine den Rinnenboden bildende zweite Wandung gebildet ist, wobei die innenliegende erste Wandung zumindest eine höckerartige Ausformung in Verlängerung eines Durchzugs auf der der U-förmigen Rinne zugewandten Seite aufweist, welche die Breite der U-förmigen Rinne zwischen dem aufgestellten Randbereich und der ersten Wandung begrenzt und sich vom Rinnenboden hin zum der U-förmigen Rinne zugewandten Endbereich des Durchzugs erstreckt, welche zur Erzeugung einer Einführschräge für Rohre dient.An embodiment of the invention relates to a tube plate for a heat exchanger, with a slot-like openings having bottom portion, the slot-like openings are surrounded by passages and the tube sheet has a raised edge region, wherein between the passages and the erected edge region a U-shaped groove as a receiving area for the foot of a box-like cover is formed, wherein the U-shaped groove is formed by an inner first wall, the erected edge region and a second wall forming the channel bottom, wherein the inner first wall at least a hump-like shape in extension of a passage on the U having-shaped groove facing side which limits the width of the U-shaped groove between the erected edge region and the first wall and extending from the groove bottom toward the U-shaped groove facing end portion of the passage, which for generating an insertion bevel for pipes.
Dabei ist es vorteilhaft, wenn durch die eingeformte Vertiefung eine Materialverlagerung hin zur von der U-förmigen Rinne abgewandten Seite der ersten Wandung ausgebildet ist.It is advantageous if a material displacement is formed toward the side facing away from the U-shaped groove side of the first wall by the molded recess.
Durch eine höckerartige Ausformung aus der inneren Wandung kann die Breite der U-förmigen Rinne besonders vorteilhaft begrenzt werden. Gleichzeitig kann die Höhe der U-förmigen Rinne an der Innenseite durch die höckerartige Ausformung definiert werden. Die höckerartige Ausformung kann dabei insbesondere abhängig von der jeweiligen Breite der Durchzüge angepasst werden. Auf diese Weise können Rohrböden mit einer identischen Grundbreite erzeugt werden, welche jeweils unterschiedlich breite Öffnungen und Durchzüge aufweisen. Dies ist vorteilhaft, da für die unterschiedlichen Rohrböden die gleichen Fertigungsmaschinen verwendet werden können und nur die jeweiligen Tiefziehwerkzeuge angepasst werden müssen. Außerdem kann so eine standardisierte Breite für die Rohrböden auch bei unterschiedlich breiten Rohren gewährleistet werden, wodurch die Bauraumanforderungen der erzeugten Wärmeübertrager vereinheitlicht werden können.By a hump-like shape of the inner wall, the width of the U-shaped channel can be limited particularly advantageous. At the same time, the height of the U-shaped groove on the inside can be defined by the hump-like shape. The hump-like shape can be adjusted in particular depending on the width of the passages. In this way, tube sheets can be produced with an identical basic width, which each have different widths openings and passages. This is advantageous because the same production machines can be used for the different tube sheets and only the respective thermoforming tools must be adapted. In addition, a standardized width for the tube sheets can be guaranteed even with pipes of different widths, whereby the space requirements of the heat exchanger generated can be standardized.
Durch eine eingeformte Vertiefung kann eine gezielte Materialverlagerung erreicht werden. Es kann so eine größere Materialstärke insbesondere an der von der U-förmigen Rinne abgewandten Seite der inneren Wandung erreicht werden, da zusätzlich Material durch das Einformen der Vertiefung dorthin verlagert wird. Dies ist insbesondere vorteilhaft, um ausreichend groß dimensionierte Einführschrägen zur Montage der Rohre am Rohrboden erzeugen zu können.Through a molded recess, a targeted material shift can be achieved. It can be achieved as a greater material thickness, in particular on the side facing away from the U-shaped groove side of the inner wall, as additional material is displaced by the molding of the recess there. This is particularly advantageous for being able to produce sufficiently large chamfers for mounting the tubes on the tubesheet.
Durch eine Anpassung der höckerartigen Ausformung kann der Übergangsbereich zwischen der U-förmigen Rinne und dem Endbereich des Durchzugs individuell ausgestaltet werden, so dass eine ausreichende Führung und Fixierung für den Fußbereich eines kastenartigen Deckels gegeben ist und gleichzeitig eine ausreichende Materialstärke für die Ausbildung von Einführschrägen zum Erleichtern der Rohrmontage verbleibt.By adjusting the hump-like shape, the transition region between the U-shaped groove and the end portion of the passage can be configured individually, so that a sufficient guidance and fixation for the foot of a box-like lid is given and at the same time a sufficient material thickness for the formation of insertion bevels for Facilitates the pipe assembly remains.
Darüber hinaus ist es vorteilhaft, wenn die Auslenkung der höckerartigen Ausformung aus der inneren Wandung ausgehend vom Rinnenboden hin zum jeweiligen Durchzug zunimmt. Dies ist vorteilhaft, da somit eine schräge Fläche erzeugt wird, welche der U-förmigen Rinne zugewandt ist und als Zentrierhilfe für den Fußbereich eines kastenartigen Deckels dienen kann.Moreover, it is advantageous if the deflection of the hump-like formation from the inner wall, starting from the channel bottom, increases toward the respective passage. This is advantageous since an inclined surface is thus produced, which faces the U-shaped groove and can serve as a centering aid for the foot region of a box-like cover.
Auch ist es vorteilhaft, wenn die höckerartige Ausformung sich in den Bodenbereich hinein erstreckt und den Durchzug zumindest teilweise umschließt. Dies ist besonders vorteilhaft, um eine höhere Stabilität zu erzeugen und gleichzeitig weichere Übergänge zwischen dem Durchzug und der höckerartigen Ausformung beziehungsweise der inneren Wandung zu erreichen.It is also advantageous if the hump-like shape extends into the bottom area and at least partially surrounds the passage. This is particularly advantageous in order to produce a higher stability and at the same time to achieve smoother transitions between the draft and the bump-like formation or the inner wall.
Auch ist es zweckmäßig, wenn die erste Wandung an ihrer von der U-förmigen Rinne abgewandten Seite eine Einführschräge aufweist, wobei die Einführschräge an der höckerartigen Ausformung angeordnet ist und die Einführschräge eine Verjüngung der durch die Durchzüge umrandeten langlochartigen Öffnungen erzeugt.It is also expedient if the first wall has an insertion bevel on its side facing away from the U-shaped groove, wherein the insertion bevel is arranged on the bump-like formation and the lead-in bevel produces a narrowing of the slot-like openings framed by the passages.
Eine Einführschräge ist vorteilhaft, um das Einführen der Rohre in die durch die Durchzüge umrandeten Öffnungen zu erleichtern. Dabei ist es insbesondere vorteilhaft, wenn die Einführschrägen in Bereichen des Rohrbodens ausgebildet sind, welcher eine ausreichende Materialdicke aufweist, um eine genügend lange Einführschräge auszubilden.An insertion bevel is advantageous in order to facilitate the insertion of the tubes into the openings framed by the passages. It is particularly advantageous if the chamfers are formed in areas of the tube sheet, which has a sufficient material thickness to form a sufficiently long insertion bevel.

Eine Einführschräge an der eingeformten Vertiefung ist vorteilhaft, da durch die Vertiefung eine Materialanhäufung erzeugt wird, welcher eine ausreichend groß dimensionierte Einführschräge ermöglicht.Moreover, it is advantageous if the insertion bevel is formed on the molded-in depression. An insertion bevel on the molded-in depression is advantageous because an accumulation of material is created by the depression, which allows a sufficiently large insertion bevel.
Ein weiteres bevorzugtes Ausführungsbeispiel ist dadurch gekennzeichnet, dass die langlochartigen Öffnungen zwei sich gegenüberliegende Schmalseiten aufweisen und zwei sich gegenüberliegende Breitseiten aufweisen, wobei eine langlochartige Öffnung an der Schmalseite und an den der Schmalseite zugewandten Endbereichen der Breitseiten durch Einführschrägen verjüngt wird. Es ist besonders vorteilhaft, wenn sowohl an der Schmalseite als auch an den Breitseiten Einführschrägen ausgebildet sind, um eine möglichst genaue und einfache Fertigung zu ermöglichen. Insbesondere das Einführen der Rohre wird hierdurch erleichtert.A further preferred embodiment is characterized in that the slot-like openings have two opposite narrow sides and have two opposite broad sides, wherein a slot-like opening on the narrow side and the narrow side facing end portions the broadsides is tapered by insertion bevels. It is particularly advantageous if insertion bevels are formed both on the narrow side and on the broad sides in order to allow the most accurate and simple production possible. In particular, the insertion of the tubes is thereby facilitated.
Weiterhin ist es besonders vorteilhaft, wenn die höckerartige Ausformung und/oder die Vertiefung in der höckerartigen Ausformung in den Rohrboden eingeprägt ist und/oder durch Tiefziehen eingeformt ist. Das Einprägen und/oder Tiefziehen ist vorteilhaft, um die höckerartige Ausformung und die Vertiefung mit den gleichen Herstellverfahren zu erzeugen, wie den Rest des Rohrbodens. Dies vereinfacht die Produktion und senkt somit die Kosten.Furthermore, it is particularly advantageous if the hump-like shape and / or the recess in the bump-like shape is embossed into the tube sheet and / or is formed by deep-drawing. The embossing and / or deep-drawing is advantageous in order to produce the hump-like shape and the recess with the same manufacturing method, as the rest of the tube sheet. This simplifies production and thus reduces costs.
Auch ist es zu bevorzugen, wenn die erste Wandung und die zur U-förmigen Rinne gerichtete Oberfläche der höckerartigen Ausformung in einem Winkel größer als 90 Grad zum Rinnenboden ausgerichtet sind. Ein Winkel größer als 90 Grad ist vorteilhaft, um eine Schräge zu erzeugen, welche ein vorteilhaftes Einsetzen des Fußbereichs eines kastenartigen Deckels in die U-förmige Rinne ermöglicht.It is also preferable if the first wall and the surface of the bump-like formation facing the U-shaped groove are aligned at an angle greater than 90 degrees to the channel bottom. An angle greater than 90 degrees is advantageous to create a slope which allows for an advantageous insertion of the foot region of a box-like lid into the U-shaped groove.
Auch ist es vorteilhaft, wenn die der U-förmigen Rinne zugewandte Seite der höckerartigen Ausformung eine Zentrierhilfe für das Einsetzen des kastenartigen Deckels in die U-förmige Rinne bildet.It is also advantageous if the U-shaped groove facing side of the hump-like formation forms a centering aid for the insertion of the box-like lid in the U-shaped groove.
