Description

Die vorliegende Erfindung betrifft ein Sammelkastenprofil eines Wärmetauschers, gemäß dem Oberbegriff des Anspruchs 1. US 5236042 A offenbart ein derartigen Sammelkastenprofil.The present invention relates to a collection box profile of a heat exchanger, according to the preamble of claim 1. US 5236042 A discloses such a collection box profile.

Gattungsgemäße Sammelkastenprofile von Wärmetauschern bestehen in der Regel aus zwei Seitenwänden und eine die beiden Seitenwände verbindende Deckenwand, welche zusammen einen Sammelraum von drei Seiten umschließen. Das so gebildete Sammelkastenprofil ist üblicherweise mit einer als vierte Seite des Sammelraumes dienenden Bodenplatte verschweißt oder verlötet, an die die Rohre und Lamellen des Wärmetauschers angebunden sind.Generic collection box profiles of heat exchangers usually consist of two side walls and a connecting the two side walls ceiling wall, which together enclose a plenum from three sides. The collection box profile thus formed is usually welded or soldered to a serving as a fourth side of the plenum floor plate to which the tubes and fins of the heat exchanger are connected.

In einer der Seitenwände oder der Deckenwand ist dabei eine Öffnung vorgesehen in die ein Stutzen eingebracht werden kann, über welchen eine Kühlflüssigkeit in das Sammelkastenprofil eingebracht werden kann oder aus diesem heraus abgeführt werden kann. Zur Befestigung dieser Stutzen werden üblicherweise Flansche oder Muffen auf die Seitenwand oder die Deckenwand aufgeschweißt oder angelötet.In one of the side walls or the ceiling wall while an opening is provided in which a nozzle can be introduced, via which a cooling liquid can be introduced into the collection box profile or can be removed from this. To attach these nozzles usually flanges or sleeves are welded or soldered to the side wall or ceiling wall.

Problematisch bei diesen auf den Seitenwänden oder der Deckenwand angebracht Flanschen oder Muffen ist, dass die anschließende Weiterverarbeitung des Sammelkastenprofils nur manuell möglich ist, da die aufgesetzten Flansche bzw. Muffen Störkanten bilden, aufgrund derer ein Einsetzen eines solchen Sammelkastenprofils in einem Schweißautomaten nicht möglich ist.The problem with these mounted on the side walls or the ceiling wall flanges or sleeves is that the subsequent processing of the collection box profile is only possible manually, since the patch flanges or sleeves form interference edges, due to which insertion of such a collection box profile in an automatic welding machine is not possible.

Aufgabe der vorliegenden Erfindung ist es, ein gegenüber dem Stand der Technik kompakteres Sammelkastenprofil eines Wärmetauschers bereitzustellen, mit dem eine schnellere und kostengünstigere Anbindung des Sammelkastenprofils an die weiteren Bauteile des Wärmetauschers ermöglicht ist.Object of the present invention is to provide a comparison with the prior art more compact collection box profile of a heat exchanger, with a faster and more cost-effective connection of the collection box profile is made possible to the other components of the heat exchanger.

Diese Aufgabe wird durch ein Sammelkastenprofil eines Wärmetauschers mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a collection box profile of a heat exchanger with the features of claim 1.

Erfindungsgemäß weist mindestens eine der Seitenwände und/oder die Deckenwand Befestigungsbohrungen zur form- oder reibschlüssigen Festlegung von Befestigungsmitteln zur Festlegung des Stutzens an einer der Seitenwände oder der Deckenwand auf.According to the invention, at least one of the side walls and / or the top wall mounting holes for the positive or frictional fixing of fastening means for fixing the nozzle to one of the side walls or the ceiling wall.

Durch die Integration der Befestigungsbohrungen in die Seitenwand und/oder die Deckenwand des Sammelkastenprofils kann die Anbringung von Flanschen oder Muffen an dem Sammelkastenprofil entfallen, so dass das Sammelkastenprofil beispielsweise in einen Längsschweißautomaten einsetzbar ist, in dem das Sammelkastenprofil mit dem Netz des Wärmetauschers in Blockbreite verschweißt werden kann. Dadurch lassen sich die Fertigungszeiten eines Sammelkastenprofils erheblich reduzieren.Through the integration of the mounting holes in the side wall and / or the ceiling wall of the header box attachment of flanges or sleeves can be omitted on the collection box profile, so that the collection box profile can be used, for example, in a longitudinal welding, in which welded the collection box profile with the network of the heat exchanger in block width can be. As a result, the production times of a collection box profile can be significantly reduced.

Vorteilhafte Ausführungsvarianten der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.

Gemäß einer vorteilhaften Ausführungsvariante sind die Befestigungsbohrungen des Sammelkastenprofils mit einem Innengewinde ausgebildet, so dass der Stutzen mit Hilfe von Schrauben an eine der Seitenwände oder der Deckenwand angeschraubt werden kann.According to an advantageous embodiment, the mounting holes of the header box profile are formed with an internal thread, so that the socket can be screwed by means of screws to one of the side walls or the ceiling wall.

Gemäß einer weiteren vorteilhaften Ausführungsvariante der Erfindung sind die Befestigungsbohrungen als Sacklöcher ausgebildet. Dabei ist die Wanddicke der jeweiligen Seitenwand oder Deckenwand so bemessen, dass die Befestigungsbohrungen hinreichend tief von außen in die Seitenwand oder Deckenwand hinein ragen, um den beispielsweise als Schrauben ausgebildeten Befestigungsmitteln zur Befestigung des Stutzens an der Seitenwand oder Deckenwand hinreichend Halt zu bieten.According to a further advantageous embodiment of the invention, the mounting holes are formed as blind holes. The wall thickness of the respective side wall or ceiling wall is dimensioned so that the mounting holes protrude sufficiently deep from the outside into the side wall or ceiling wall to provide sufficient, for example, designed as a screw fastening means for fastening the nozzle to the side wall or ceiling wall.

Die Wanddicke mindestens einer der Seitenwände und/oder der Deckenwand ist im Bereich der Befestigungsbohrungen größer als die Wanddicke einer der Seitenwände und/oder der Deckenwand in einem Bereich ohne Befestigungsbohrungen. Damit wird erreicht, dass trotz größerer Wanddicken im Bereich der Befestigungsbohrungen ein hinreichend großer Sammelraum innerhalb der Seitenwände und der Deckenwand verbleibt.The wall thickness of at least one of the side walls and / or the ceiling wall is greater in the region of the fastening bores than the wall thickness of one of the side walls and / or the ceiling wall in a region without fastening bores. This ensures that, despite larger wall thicknesses in the region of the fastening bores, a sufficiently large collecting space remains within the side walls and the ceiling wall.

Bevorzugt geht eine der Seitenwände zum Sammelraum hin konkav und mit konstanter Wanddicke geformt in die Deckenwand über. Die Wanddicke der anderen der Seitenwände zusammen mit der Deckenwand ist so ausgebildet, dass die andere der Seitenwände zusammen mit der Deckenwand im Querschnitt jeweils ein rechtwinkliges Dreieck bildet, wobei die dem Sammelraum abgewandte Außenseite der anderen der Seitenwände und der Deckenwand senkrecht aufeinander stehen und wobei die Befestigungsbohrungen im Bereich der anderen der Seitenwände zusammen mit der Deckenwand vorgesehen sind.Preferably, one of the side walls is concave and shaped with a constant wall thickness into the ceiling wall towards the collecting space. The wall thickness of the other of the side walls together with the ceiling wall is formed so that the other of the side walls together with the ceiling wall in cross-section each forms a right triangle, wherein the collecting space facing away from the outside of the other of the side walls and the top wall perpendicular to each other and wherein the Mounting holes in the area the other of the side walls are provided together with the ceiling wall.

Durch diese Ausbildung des Sammelkastenprofils als zumindest teilweises Rundprofil ist eine erhebliche Materialeinsparung zur Ausbildung der Seitenwände und Deckenwand des Sammelkastenprofils möglich.This design of the collection box profile as at least partial round profile a significant material savings for the formation of the side walls and ceiling wall of the header box profile is possible.

Gemäß einer alternativen Ausführungsvariante ist die Wanddicke der Seitenwände zusammen mit der Deckenwand so ausgebildet, dass jede der Seitenwände zusammen mit der Deckenwand im Querschnitt jeweils ein rechtwinkliges Dreieck bildet. Dadurch können auf beiden Seiten des Sammelkastenprofils Aufnahmeöffnungen sowie Befestigungsbohrungen eingebracht werden.According to an alternative embodiment, the wall thickness of the side walls is formed together with the ceiling wall so that each of the side walls together with the ceiling wall in cross-section each forms a right-angled triangle. As a result, receiving openings and fastening bores can be introduced on both sides of the collection box profile.

Um auch im Bereich der Befestigungsbohrungen ein möglichst material sparendes Sammelkastenprofil auszubilden, ist die Hypotenuse der zu einem rechtwinkligen Dreieck geformten einen der Seitenwände zusammen mit der Deckenwand als gewellte oder gezackte Linie ausgebildet, um im Bereich der von außen in das Sammelkastenprofil hinein ragende Befestigungsbohrungen eine hinreichende Materialdicke zu gewährleisten und in den übrigen Bereichen Material einzusparen und gleichzeitig einen größeren Sammelraum zu schaffen.In order to form a material-saving collection box profile as possible in the area of the fastening bores, the hypotenuse of the rectangular walls formed to one of the side walls together with the ceiling wall as a corrugated or serrated line to sufficient in the region of the projecting into the outside of the collection box mounting holes To ensure material thickness and save in the remaining areas material and at the same time to create a larger collection space.

Das Sammelkastenprofil ist bevorzugt als einstückiges Strangpressprofil ausgebildet, wodurch eine einfache Herstellung des erfindungsgemäßen Sammelkastenprofils ermöglicht ist.The collection box profile is preferably designed as a one-piece extruded profile, whereby a simple production of the collection box profile according to the invention is made possible.

Diese Begriffe sind nicht einschränkend zu verstehen, das heißt, durch verschiedene Arbeitsstellungen oder die spiegelsymmetrische Auslegung oder dergleichen können sich diese Bezüge ändern.In the following description of the figures, terms such as above, below, left, right, front, back, etc. refer exclusively to the exemplary representation and position of the collection box profile, the side walls and the like selected in the respective figures. These terms are not intended to be limiting, that is to say, by different working positions or the mirror-symmetrical design or the like, these references may change.

Die Figuren 1 und 2 zeigen eine erste Ausführungsvariante eines erfindungsgemäßen Sammelkastens 1 mit einem von zwei Seitenwänden 6, 7 und einer Deckenwand 5 um von drei Seiten umgebenen Sammelraum 9, der mit seiner der Deckenwand 5 gegenüber liegenden Seite mit einem üblichen Wärmetauschernetz, bestehend aus mehreren parallel angeordneten und Kühlkanäle bildenden Rohren und zwischen diesen angeordneten wellenförmig ausgebildeten Lamellen verbindbar ist.The FIGS. 1 and 2 show a first embodiment of a header tank according to the invention 1 with one of two side walls 6, 7 and a ceiling wall 5 surrounded by three sides collecting space 9, with its the ceiling wall 5 opposite side with a conventional heat exchanger network, consisting of several parallel and cooling channels forming Tubes and arranged between these wave-shaped fins is connectable.

Das Sammelkastenprofil 1 ist vorzugsweise als Strangpressprofil ausgebildet und erstreckt sich entlang einer Längsrichtung y zwischen zwei endseitigen Stirnflächen 2.The collection box profile 1 is preferably designed as an extruded profile and extends along a longitudinal direction y between two end-side end faces 2.

In wenigstens einer der Seitenwände 6, 7 und/oder der Deckenwand 5 sind mindestens eine Aufnahmeöffnung 3 zur Aufnahme eines Stutzens vorgesehen, über den ein Kühlmedium, beispielsweise Öl, Luft oder Wasser, in das Sammelkastenprofil eingeführt oder aus diesem herausgeführt werden kann.In at least one of the side walls 6, 7 and / or the ceiling wall 5 at least one receiving opening 3 are provided for receiving a nozzle, via which a cooling medium, for example oil, air or water, can be introduced into the collection box profile or led out of this.

Um die Aufnahmeöffnung 3 herum sind mehrere Befestigungsbohrungen 4 zur form- oder reibschlüssigen Festlegung von Befestigungsmitteln zur Festlegung des Stutzens vorgesehen, so dass der Stutzen ohne Verbindung zusätzlicher auf dem Sammelkastenprofil 1 aufzubringende Halterungen wie beispielsweise Muffen oder Flansche, welche bei im Stand der Technik bekannten Sammelkastenprofilen außen auf einer Seitenwand oder Deckenwand angeschweißt oder gelötet sind, fixierbar ist.Around the receiving opening 3 around several mounting holes 4 are provided for positive or frictional fixing of fasteners for fixing the nozzle so that the nozzle without connecting additional applied to the header box 1 brackets such as sleeves or flanges, which in known in the art collection box profiles are externally welded or soldered on a side wall or ceiling wall, can be fixed.

Wie in Figur 3 und 4 zu erkennen ist, sind die Befestigungsbohrungen 4 bevorzugt als Sacklöcher ausgebildet, die bezüglich des Sammelraums 9 von außen in die Seitenwand 6 oder die Deckenwand 5 eingebracht sind. Die Materialdicke des Sammelkastenprofils 1 in diesem Bereich ist dazu entsprechend angepasst, d.h. dass die Wanddicke d im Bereich der Seitenwand 6 und der Deckenwand 5 hier so bemessen ist, dass sie größer ist als die Tiefe der Befestigungsbohrungen 4.As in FIG. 3 and 4 can be seen, the mounting holes 4 are preferably formed as blind holes, which are introduced with respect to the collecting space 9 from the outside into the side wall 6 or the ceiling wall 5. The material thickness of the collection box profile 1 in this area is adapted accordingly, ie that the wall thickness d in the region of the side wall 6 and the ceiling wall 5 is dimensioned here so that it is greater than the depth of the mounting holes. 4

Bei der in den Figuren 1 bis 5 gezeigten Ausführungsvariante des Sammelkastenprofils ist im Bereich des Sammelkastenprofils, hier die Seitenwand 7 zum Sammelraum 9 hin konkav und mit konstanter Wanddicke d geformt. Die Seitenwand 7 geht dabei kontinuierlich in die Deckenwand 5 über. Die Wanddicke d der Deckenwand 5 und der Seitenwand 6 hingegen ist hier so bemessen, dass die Seitenwand 6 zusammen mit der Deckenwand 5 im Querschnitt ein rechtwinkliges Dreieck bilden, wobei die dem Sammelraum 9 abgewandte Außenseite der Seitenwand 6 und der Deckenwand 5 senkrecht aufeinander stehen. Die Befestigungsbohrungen 4 und die Aufnahmeöffnung 3 befinden sich dabei im Bereich der Seitenwand 6 und der Deckenwand 5, wo die Wanddicke den Befestigungsbohrungen 4 entsprechend größer ist. Durch die verschiedenen Bereiche des Sammelkastenprofils mit unterschiedlichen Wanddicken ist eine optimale Materialverteilung gewährleistet, wobei größere Wanddicken nur dort vorgesehen sind, wo Aufnahmeöffnungen 3 um diese umgebende Befestigungsbohrungen 4 vorgesehen sind.In the in the FIGS. 1 to 5 shown embodiment of the collection box profile is formed in the region of the collection box profile, here the side wall 7 to the collection chamber 9 out concave and constant wall thickness d. The side wall 7 goes continuously into the ceiling wall 5 over. The wall thickness d of the ceiling wall 5 and the side wall 6, however, is here dimensioned so that the side wall 6 together with the ceiling wall 5 in cross section form a right triangle, wherein the collecting chamber 9 facing away from the outside of the side wall 6 and the top wall 5 are perpendicular to each other. The mounting holes 4 and the receiving opening 3 are located in the region of the side wall 6 and the ceiling wall 5, where the wall thickness of the mounting holes 4 is correspondingly larger. Due to the different areas of the collection box profile with different wall thicknesses optimal material distribution is ensured, with larger wall thicknesses are only provided where receiving openings 3 are provided around these surrounding mounting holes 4.

In den Figuren 6 bis 9 ist eine weitere Ausführungsvariante eines erfindungsgemäßen Sammelkastenprofils 11 gezeigt, bei dem in Längsrichtung y betrachtet beide Sammelkastenprofilhälften mit vergrößerten Wanddicken ausgebildet sind. Dadurch nimmt das Sammelkastenprofil 11 insgesamt etwa eine quaderförmige Gestalt an, wobei der Sammelraum 9 innerhalb der Seitenwände 16, 17 und der Deckenwand 15 etwa dreieckig geformt ist, so dass bei diesem Sammelkastenprofil 11 in Längsrichtung y betrachtet auf beiden Seiten des Sammelkastenprofils 11 Aufnahmeöffnungen 3 sowie diese umgebende Befestigungsbohrungen 4 eingebracht werden können.In the FIGS. 6 to 9 shows a further embodiment of a collection box profile 11 according to the invention, in which viewed in the longitudinal direction y both collection box profile halves are formed with increased wall thicknesses. As a result, the collection box profile 11 assumes a total of approximately a cuboid shape, wherein the collecting space 9 is formed approximately triangular within the side walls 16, 17 and the top wall 15, so that viewed in this collection box profile 11 in the longitudinal direction y on both sides of the Collection box profile 11 receiving openings 3 and these surrounding mounting holes 4 can be introduced.

Die Befestigungsbohrungen 4 sind bei beiden Ausführungsvarianten vorzugsweise mit einem Innengewinde versehen, so dass als Befestigungsmittel zur Festlegung des bzw. der Stutzen Schrauben eingesetzt werden können, die in die Befestigungsbohrungen 4 eingeschraubt werden können.The mounting holes 4 are preferably provided in both embodiments with an internal thread, so that can be used as fastening means for fixing the or the nozzle screws that can be screwed into the mounting holes 4.

Die im Querschnitt jeweils ein rechtwinkliges Dreieck bildenden Seitenwände 16, 17 zusammen mit der Deckenwand 15 weisen dabei eine sich in Längsrichtung y erstreckende Innenwand auf, welche im rechtwinkligen Dreieck die Hypotenuse darstellt. Die Innenseite 8 ist zur optimalen Materialausnutzung und Gestaltung von optimalen Strömungsverhältnissen als gewellte oder gezackte Linie ausgebildet.The cross-sectional respectively in each case a right-angled triangle forming side walls 16, 17 together with the top wall 15 in this case have a longitudinally extending y inner wall, which represents the hypotenuse in a right triangle. The inside 8 is designed for optimal material utilization and design of optimal flow conditions as a wavy or jagged line.

Mit den beiden Ausführungsvarianten der Sammelkastenprofile 1, 11 sind dadurch Materialeinsparungen gegenüber herkömmlichen Sammelkastenprofilen von bis zu 30 Prozent ermöglicht. Des Weiteren müssen keine Flansche bzw. Muffen auf den Sammelkastenprofilen angeschweißt oder gelötet werden, wodurch die Fertigungszeiten eines Sammelkastenprofils reduziert werden. Durch die Integration der Aufnahmeöffnungen 3 und Befestigungsbohrungen 4 sind beliebig viele Anschlüsse in beliebigen Größen ermöglicht. Die Anschlüsse selbst können dabei wahlweise vertikal oder horizontal, d.h. an den Seitenwänden 6, 7, 16, 17 oder der Deckenwand 5, 15 integriert werden.With the two variants of the collection box profiles 1, 11 thereby material savings over conventional collection box profiles of up to 30 percent are possible. Furthermore, no flanges or sleeves need to be welded or soldered to the header boxes, thereby reducing the manufacturing times of a header box profile. The integration of the receiving openings 3 and mounting holes 4 any number of ports in any size possible. The connections themselves can either vertically or horizontally, i. be integrated on the side walls 6, 7, 16, 17 or the ceiling wall 5, 15.

Auch ein Bypassventil kann direkt in das Sammelkastenprofil ohne zusätzliche Muffe integriert werden.A bypass valve can also be integrated directly into the collection box profile without an additional sleeve.

Des Weiteren ist durch den Wegfall der bei herkömmlichen Sammelkastenprofilen außen anzubringenden Muffen bzw. Flanschen ein kompakterer Einbau des Wärmetauschers in einem den Wärmetauscher aufnehmenden Gerät ermöglicht. Schließlich ist durch den Wegfall der Muffen und Flansche außen am Sammelkastenprofil auch eine automatische Verschweißung des Wärmetauschers, beispielsweise in einem Längsschweißautomaten ermöglicht.Furthermore, a more compact installation of the heat exchanger in a device accommodating the heat exchanger is made possible by the elimination of the joints or flanges to be mounted outside in the case of conventional collection box profiles. Finally, the omission of the sleeves and flanges on the outside of the collection box profile also enables automatic welding of the heat exchanger, for example in a longitudinal welding machine.
