Entsprechend der Erfindung werden die Rohre an den Rohrenden derart aufgeweitet,
dass einerseits lange Verbindungsflächen gebildet werden zur Verbindung der Rohrenden
mit benachbarten Rohrenden und andererseits kurze Verbindungsflächen gebildet werden
zur Verbindung mit einem in den Endbereichen der Rohre aufgesetzten Sammelbehälter.
Die Aufweitung des Rohrendes erfolgt senkrecht zur Längsseite des Rohres, wobei
senkrecht zur Schmalseite des Rohres eine Verschmälerung eintritt. Durch die
Verbreiterung des Rohres senkrecht zur Längsseite des Rohres wird eine unmittelbare
Anlage der langen Verbindungsflächen eines Rohrendes mit einer Verbindungsfläche
eines benachbarten Rohrendes ermöglicht. Das Vorsehen eines Rohrbodens kann daher
entfallen. Weiterhin kann der Sammelbehälter mit dem Rohrblock unmittelbar an den
außenseitigen Verbindungsflächen, insbesondere an den kurzen Verbindungsflächen,
verbunden werden, die sich unter Verringerung der räumlichen Ausdehnung des Rohres
senkrecht zur Schmalseite in Querrichtung des Rohres erstrecken. Hierdurch wird eine
wesentliche Verringerung des Platzbedarfs des Wärmetauschers in seiner Tiefe erzielt.
Daneben kann durch die unmittelbare Anlage des Sammelbehälters an die kurzen
Verbindungsflächen ein Rohrrahmen entfallen, so dass Material gespart wird.
Nach einer vorteilhaften Ausbildung der Erfindung wird die Verschmälerung an den
Schmalseiten des Rohres derart bemessen, dass sie größer oder gleich der
Schenkeldicke des Sammelbehälters ist. Dadurch wird erreicht, dass der Wärmetauscher
in seiner Gesamttiefe nicht grösser als die Rohrblocktiefe ausgebildet ist.According to the invention, the tubes are widened at the tube ends such that on the one hand long connecting surfaces are formed for connecting the tube ends with adjacent tube ends and on the other hand short connecting surfaces are formed for connection to a collecting container placed in the end regions of the tubes. The expansion of the pipe end is perpendicular to the longitudinal side of the tube, wherein perpendicular to the narrow side of the tube, a narrowing occurs. Due to the widening of the tube perpendicular to the longitudinal side of the tube, a direct contact of the long connecting surfaces of a pipe end with a connecting surface of an adjacent pipe end is made possible. The provision of a tube plate can therefore be omitted. Furthermore, the collecting container can be connected to the tube block directly on the outside connecting surfaces, in particular on the short connecting surfaces, which extend while reducing the spatial extent of the tube perpendicular to the narrow side in the transverse direction of the tube. As a result, a substantial reduction in the space requirement of the heat exchanger is achieved in its depth. In addition, can be omitted by the immediate investment of the collector to the short connecting surfaces a tubular frame, so that material is saved.

Fig. 1 zeigt eine Vorderansicht eines Wärmetauschers 10 mit parallel
verlaufenden Rohren 11, die sich von einem Sammelbehälter 12 zu einem
gegenüberliegenden Sammelbehälter 13 erstrecken, der in der Automobiltechnik
zur Motorkühlung eingesetzt werden kann. Seitenteile
8 begrenzen den Wärmetauscher 10 in vertikaler Richtung und sind
endseitig jeweils mit den Sammelbehältern 12 und 13 verbunden. Der
Sammelbehälter 12 weist in einem Endbereich einen Zuführstutzen 6
zur Zuführung eines zu kühlenden Mediums in den Sammelbehälter 12
auf. Das zu kühlende Medium verteilt sich in dem Sammelbehälter 12
und wird über die Rohre 11 zu dem zweiten Sammelbehälter 13 geleitet,
von dem es über einen Abführstutzen 7 aus dem Sammelbehälter 13
herausgeleitet wird. Fig. 1 shows a front view of a
Wie aus Fig. 2 und Fig. 3 ersichtlich, sind die Rohre 11 als flachovale,
bzw. im Querschnitt rechteckförmige Rohre ausgebildet mit gegenüberliegenden
Längsseiten 14 und seitlich angeordneten Schmalseiten
15. In einem Endbereich sind die Rohrenden 16 senkrecht zur
Längsseite 14 aufgeweitet ausgebildet. Die Längsseiten 14 des Rohres
11 erstrecken sich über konusförmig verlaufende lange Übergangsflächen
17 zu langen Verbindungsflächen 18 des Rohrendes 16. Die
Schmalseiten 15 des Rohres 11 verschmälern sich in Richtung des Rohrendes
16 über eine kurze Übergangsfläche 19, die sich konusförmig
in Richtung einer Mittelachse 20 des Rohres 11 erstreckt, zu einer
kurzen Verbindungsfläche 22. Die Rohre 11 sind in einer Reihe angeordnet,
wobei zwischen den Rohren 11 luftführende Wellrippen 21 angeordnet
sind. Während die Längsseiten 14 zu einer langen Verbindungsfläche
18 aufgeweitet werden, werden die Schmalseiten 15 zu einer
kurzen Verbindungsfläche 22 verschmälert. Wie aus Fig. 3 ersichtlich,
ist das Rohrende 16 im Querschnitt rechteckförmig ausgebildet,
und zwar in Form der parallel verlaufenden, gegenüberliegenden
langen Verbindungsfläche 18 und der rechtwinklig dazu angeordneten,
gegenüberliegenden kurzen Verbindungsfläche 22. Die Aufweitung
erfolgt derart, daß die Umfangslänge des Rohrendes 16 entlang der
langen und kurzen Verbindungsflächen 18 und 22 gleich der Umfangsfläche
des Rohres 11 im Bereich der Längs- und Schmalseiten 14 und
15 ist, so daß die Dicke der langen und kurzen Verbindungsflächen 18
und 22 gleich der Dicke der Längs- und Schmalseiten 14 und 15 ist.
Eine Oberflächenvergrößerung des Rohres 11 an den Rohrenden 16 erfolgt
nicht.As can be seen from FIGS. 2 and 3 , the
Wie aus Fig. 2 zu ersehen ist, liegen die langen Verbindungsflächen
18 an den langen Verbindungsflächen 18 benachbarter Rohrenden 16 an
und sind mit diesen durch Lötung verbunden. Die Neigung der
konusförmigen langen Übergangsflächen 17 wird durch die Breite der
Wellrippen 21 festgelegt. Je größer die Tiefe der Wellrippem 21 ist,
desto größer muß der Winkel der langen Übergangsflächen 17 bezüglich
der Mittelachse 20 sein, damit die benachbarten langen
Verbindungsflächen 18 aneinander liegen können.As can be seen from Fig. 2 , the long connecting
Gemäß einem ersten Ausführungsbeispiel nach Fig. 4 und Fig. 6 wird
auf die Rohrenden 16 ein U-förmiger Sammelbehälter 23 mit einem ebenen
Schenkel 24 und einem gekrümmten Schenkel 25 aufgesetzt. Die
Schenkelenden 26 und 27 liegen an den kurzen Verbindungsflächen 22
an und sind mit diesen verlötet. Endseitig sind die Schenkelenden
26, 27 formschlüssig in dafür vorgesehene Nuten des Seitenteils 8
eingepaßt und werden mit diesen gleichzeitig durch Lötung verbunden.
Dadurch, daß die kurzen Verbindungsflächen 22 im Vergleich zu den
Schmalseiten 15 in Richtung zur Mittelachse 20 angeordnet sind, wobei
die Abstandsverringerung zur Mittelachse 20 mindestens gleich
oder größer ist als die Dicke der Schenkelenden 26, 27, steht der
Sammelbehälter 23 in seitlicher Richtung der Rohre 11 nicht über.
Die seitliche Erstreckung der Sammelbehälter 23 ist somit gleich
oder geringer als die Quererstreckung der Rohre 11. Damit wird eine
erhebliche Reduzierung des Platzbedarfes des Wärmetauschers 10 gewährleistet,
wobei der Platzbedarf lediglich durch die Tiefe des
Rohres 11 (Abstand der Schmalseiten 15 zur gegenüberliegenden
Schmalseite 15) festgelegt wird. An dem ebenen Schenkel 24 des Sammelbehälters
23 ist der Zuführstutzen 6 zur Zuführung eines zu kühlenden
Mediums angebracht.According to a first exemplary embodiment according to FIGS. 4 and 6 , a
Vorteilhafterweise wird der Sammelbehälter 23 durch Extrudieren eines
Blocks zu einem U-förmigen Profil hergestellt. Darüberhinaus
kann der Sammelbehälter 23 auch durch Walzen und anschließendes Biegen,
insbesondere durch Tiefziehen geformt werden. Dabei ist darauf
zu achten, daß durch Anlage eines geeigneten Werkzeuges in seitlicher
Richtung, nämlich an die kurzen Verbindungsflächen 22 dieselben
senkrecht zu den langen Verbindungsflächen 17 angeordnet sind, so
daß die Kante zwischen kurzer Verbindungsfläche 22 und langer Verbindungsfläche
17 einen kleinen Radius aufweist. Damit wird die Bildung
eines Zwischenraumes oder Spaltes verhindert, so daß die Schenkelenden
26, 27 des Sammelbehälters 23 mit den kurzen Verbindungsflächen
22 des Rohrblocks durch dichtende Verlötung verbunden
sind.Advantageously, the collecting
Alternativ kann der Sammelbehälter als zylinderförmiger Sammelbehälter
29 nach einem zweiten Ausführungsbeispiel gemäß Fig. 5 und Fig.
7 ausgebildet sein. Dieser Sammelbehälter 29 wird vorzugsweise durch
Tiefziehen hergestellt. Parallele Kragen 30 und 31 bilden eine Ausnehmung
des Sammelbehälters 29, in die das Rohrpaket unter Anlage
der kurzen Verbindungsflächen 22 an die Innenseiten der Kragen 30
und 31 eingesetzt wird. Je nach Anwendungsfall sind die Stirnseiten
des Sammelbehälters 29 dichtend mit einer Mantelfläche 32 des Sammelbehälters
29 verbunden. Für die Zu- bzw. Ableitung eines zu
kühlenden Mediums kann der Sammelbehälter 29 im Bereich einer Stirnfläche
eine axiale Ausnehmung aufweisen zur Anlage eines nicht dargestellten
Stutzens Der Sammelbehälter 29 umfaßt mit seinen endseitigen
Stirnflächen das an der äußeren langen Verbindungsfläche 18
anliegende Seitenteil 9 und ist mit diesen durch Lötung verbunden.
Durch Umfassen des Rohrpaketes einerseits und des Seitenteils 9 andererseits
wird auf einfache Weise ein paßgenauer Sitz des Rohrpaketes
mit gegenüberliegenden Seitenteilen 9 erzielt, so daß danach die
Verbindung dieser Bauteile miteinander in einem Arbeitsvorgang verwirklicht
werden kann.Alternatively, the collecting container may be formed as a
Vorzugsweise bestehen das aus den Wellrippen 21 und den Rohren 11
zusammengesetzte Rohrpaket und die Sammelbehälter 12, 13, 23, 29 aus
einem sortenreinen Metallwerkstoff. Die Recyclefähigkeit des
Wärmetauschers 10 wird dadurch erleichtert. Als bevorzugter Werkstoff
wird für diese Bauteile eine Aluminium-Legierung verwendet,
die eine Gewichtsreduzierung des Wärmetauschers 10, insbesondere
beim Einsatz in dem Kraftfahrzeugbau, ermöglicht. Daneben ist die
Verwendung anderer recyclefähiger Werkstoffe möglich. Es können auch
Werkstoffe aus Kupfer oder Stahl für die Rohre und Kunststoff für
den Sammelbehälter eingesetzt werden, wobei die Rohre bzw. das Rohrpaket
mit dem Sammelbehälter verklebt werden.Preferably consist of the
Im folgenden wird das Verfahren zur Herstellung des Wärmetauschers
10 dargestellt. Nachdem die zur Verbindung mit den Rohren 11
vorgesehenen Sammelbehälter 12, 13, 23 und 29 unterschiedlicher Form
durch Tiefziehen oder Extrudieren passgenau geformt worden sind,
wird der Rohrblock mit den geweiteten Rohrenden 16 in die dafür vorgesehenen
Ausnehmungen der Sammelbehälter 23 und 29 eingesetzt. Danach
werden gleichzeitig die Rohrenden 16 an den langen Verbindungsflächen
18 miteinander und die Rohrenden 16 an den kurzen Verbindungsflächen
19 mit dem Sammelbehälter 23 oder 29 verbunden. Diese
Verbindung erfolgt vorzugsweise durch Löten, wobei mindestens die
betreffenden Verbindungsstellen vorher mit einem Flußmittel besprüht
worden sind. Vorzugsweise ist dieses Flußmittel nonkorrosiv. Zur
Verbindung der betreffenden Teile eignen sich jedoch auch andere
Lötverfahren, die von dieser Erfindung miteingeschlossen sind.The following is the method of manufacturing the
Vorteilhafterweise läßt sich der Wärmetauscher 10 mit einem zweiten,
sich unmittelbar anschließenden Wärmetauscher 28 verbinden. Dieser
Wärmetauscher 28 kann beispielsweise ein Kondensator einer Klimaanlage
oder ein Ladeluftkühler sein. Der Wärmetauscher 10 kann entweder
mit einem U-förmigen Sammelbehälter 23 oder einem zylinderförmigen
Sammelbehälter 29 ausgeführt sein.Advantageously, the
Nach einem ersten Ausführungsbeispiel gemäß Fig. 8 ist der erste
Wärmetauscher 10 mit dem zweiten Wärmetauscher 28 über ein Verbindungselement
5 verbunden. Das Verbindungselement 5 ist U-förmig ausgebildet,
wobei ein erster Schenkel 33 in eine Nut 34 des Wärmetauschers
10 einfaßt und ein zweiter Schenkel 35 des Verbindungselementes
5 in eine Nut 36 des Wärmetauschers 28 einpaßt. Die Verbindung
der Schenkel 33 und 35 mit dem Wärmetauscher 10, bzw. 28 erfolgt
durch Lötung, die gleichzeitig mit der Verlötung des Rohrpaketes innerhalb
des Wärmetauschers 10 vorgenommen werden kann. Vorzugsweise
ist der Sammelbehälter 23 des Wärmetauschers 10 mit einem Sammelbehälter
37 des Wärmetauschers 31 über einen Steg 38 einstückig verbunden.
Hierdurch wird die mechanische Stabilität der aus dem Wärmetauscher
10 und dem Wärmetauscher 31 bestehenden Anordnung erhöht.According to a first exemplary embodiment according to FIG. 8 , the
Nach einem weiteren Ausführungsbeispiel gemäß Fig. 9 ist der Wärmetauscher
10 einstückig mit einem U-förmigen Verbindungselement 39
verbunden, dessen Schenkel 40 eine vorstehende Nase 41 eines benachbarten
Wärmetauschers 42 umfaßt. Der Wärmetauscher 42 weist eine
weitere bogenförmige Nase 43 auf, die auf einem Ansatzstück 44 des
Sammelbehälters 23 aufliegt. Die Nasen 41 und 43 des Wärmetauschers
42 werden mit dem Schenkel 40 bzw. dem Ansatzstück 44 des Wärmetauschers
10 durch Lötung verbunden, wobei dieser Lötvorgang gleichzeitig
mit dem Lötvorgang zur Bildung des Wärmetauschers 10 erfolgt.
Vorzugsweise weist das Ansatzstück 44 eine Ausnehmung 45 auf, die
dazu dient, nach Verbindung des aus dem Wärmetauscher 10 und dem
Wärmetauscher 42 gebildeten Wärmetauschersatzes bei eine Undichtigkeitsprüfung
eine mögliche undichte Stelle einfacher zu lokalisieren.According to a further embodiment according to FIG. 9 , the
Vorzugsweise bestehen die Wärmetauscher 28 und 42 aus einer Aluminium-Legierung,
wobei mindestens die zu verbindenden Stellen mit
eine nonkorrisiven Flußmittel versehen sind. Somit kann auf einfache
Weise in einem einzigen Arbeitsschritt jeweils die Kombination aus
einem ersten Wärmetauscher 10 mit einem Wärmetauscher 28 oder 42
hergestellt werden.Preferably, the
Nach einem weiteren Ausführungsbeispiel des Wärmetauschers gemäß
Fig. 10 ist ein U-förmiger Sammelbehälter 47 mit dem Rohrpaket jeweils
im seitlichen Bereich über ein ebenfalls U-förmiges Ansatzstück
48 verbunden. Der Sammelbehälter 47 kann als Druckguß-Werkstoff
oder Kunststoffteil ausgebildet sein. Im Bereich des Rohrendes
16 wird das Ansatzstück 48 mit einem kurzen Schenkel 49 auf die kurzen
Verbindungsflächen 22 aufgesetzt und mit diesem durch Verlöten
verbunden. Ein langer Schenkel 50 des Ansatzstückes 48 erstreckt
sich parallel zu der Schmalseite 15 des Rohres 11, wobei der Abstand
zwischen den Außenkonturen des langen und kurzen Schenkels 49, 50
kleiner oder gleich dem Abstand zwischen der kurzen Verbindungsfläche
22 und einer gedachten Verlängerung der Schmalseite 15 ist. Zur
Verbindung des Sammelbehälters 47 mit dem Ansatzstück 48 wird ein
durchgehender Dichtring 51 in die durch das Ansatzstück 48 gebildete
Nut eingesetzt und daran anschließend der Sammelbehälter 47 mit seinen
beiden Schenkeln 52, 53 auf den Dichtring 51 gedrückt und durch
Verbördelung mit den langen Schenkeln 50 des Ansatzstückes 48 fest
mit demselben verbunden. Die Schenkel 52, 53 weisen Schenkelenden 54
und 55 auf, die fluchtend mit der Nut des Ansatzstückes 48 in diese
eingesetzt werden. Dabei liegt eine innere Seite der Schenkelenden
54, 55 an dem kurzen Schenkel 49 des Ansatzstückes 48 und eine äußere
Seite der Schenkelenden 54, 55 an dem langen Schenkel 50 des
Ansatzstückes 48 an. Die ebene Bodenseite der Schenkelenden 54, 55
werden auf den Dichtring 51 gedrückt und in der Nut durch anschließende
Verbördelung gehalten, so daß eine sichere Dichtigkeit des
Sammelbehälters 47 gewährleistet ist. Die Verbördelung des Sammelbehälters
47 wird durch ein an der Außenseite der langen Schenkel 50
des Ansatzstückes 48 angreifendes Werkzeug bewirkt, wobei stellenweise
der lange Schenkel 50 unter Bildung einer Bördelkante 56 nach
innen eingedrückt wird. Nach diesem Ausführungsbeispiel wird auf
einfache Weise ein platzsparender Wärmetauscher verwirklicht, wobei
ein Sammelbehälter 47 mit seinen Enden 54, 55 in eine Nut eines mit
dem Rohrpaket verbundenen Ansatzstückes 48 eingreift.According to a further embodiment of the heat exchanger according to FIG. 10 , a
