Description
Die Erfindung betrifft einen Wärmetauscher, insbesondere für Kraftfahrzeuge.The invention relates to a heat exchanger, in particular for motor vehicles.
Wärmetauscher sind im Stand der Technik hinlänglich bekannt. Dabei sind in der Regel Rohrbündel von Flachrohren vorgesehen, wobei die Rohrenden durch Öffnungen in einen Sammelkasten reichen und dort mit dem Sammelkasten verlötet sind. Bei Thermowechsel bzw. bei thermischer Belastung auf Zug/Druck treten Risse, also Ausfälle, im Bereich der Rohr/Kastenverbindung auf. Dabei zeigt sich, dass die Ausfälle in der Regel an der Rohrschmalseite der Rohr/Kastenverbindung auftreten.Heat exchangers are well known in the art. In this case, tube bundles of flat tubes are usually provided, the pipe ends passing through openings in a collection box and there are soldered to the collection box. When changing the temperature or thermal stress on train / pressure cracks, so failures occur in the pipe / box connection. It shows that the failures usually occur on the narrow pipe side of the pipe / box connection.

Daher ist es die Aufgabe der vorliegenden Erfindung, einen Wärmetauscher zu schaffen, welcher insbesondere im Hinblick auf die Anforderungen bei Thermowechseln verbessert ist.Therefore, it is the object of the present invention to provide a heat exchanger, which is improved in particular with regard to the requirements for thermal changes.
Die Aufgabe der vorliegenden Erfindung wird mit einem Wärmetauscher gemäß Anspruch 1 gelöst.The object of the present invention is achieved with a heat exchanger according to
Ein Ausführungsbeispiel der Erfindung betrifft einen Wärmetauscher mit zumindest einem Sammelkasten mit einer Vielzahl von Rohröffnungen und mit einem Rohrbündel von Rohren, wobei die Enden der Rohre in Öffnungen des Sammelkastens eingreifen, wobei die Rohre eine Breitseite mit der Länge L1 mit gegenüberliegenden Rohrseitenwänden und zwei endseitigen Schmalseiten mit der Breite Io mit jeweils einem Rohrwandbogen aufweisen, wobei der Rohrwandbogen einen Durchmesser I1 aufweist, der größer ist als der Abstand der gegenüberliegenden Rohrseitenwände. Dadurch wird an den Schmalseiten des Rohrs im Bereich der Rohr-Öffnungsverbindung eine größere Fläche zur Verfügung gestellt, welche verlötet werden kann, so dass eine stabilere Verbindung erzeugt wird, die insbesondere auch bei Thermowechseln stabiler ist.An embodiment of the invention relates to a heat exchanger with at least one collecting box with a plurality of tube openings and with a tube bundle of tubes, wherein the ends of the tubes engage in openings of the collecting box, wherein the tubes have a broad side with the length L1 with opposite tube side walls and two end narrow sides having the width Io each having a pipe wall arc, wherein the pipe wall arc has a diameter I1 which is greater than the distance of the opposite pipe side walls. As a result, a larger area is provided on the narrow sides of the tube in the region of the tube-opening connection, which can be soldered, so that a more stable connection is produced, which is more stable especially in the case of thermal changes.
Dabei ist es vorteilhaft, wenn der Rohrwandbogen eine kreissegmentartige Kontur aufweist. Damit wird die Druckstabilität erhöht und gleichzeitig an der Schalseite die verlötbare Fläche erhöht, was die Stabilität der Verlötung verbessert.It is advantageous if the pipe wall arch has a circular segment-like contour. This increases the pressure stability and at the same time increases the solderable area on the formwork side, which improves the stability of the soldering.
Besonders vorteilhaft ist es, wenn der Rohrwandbogen einen Durchmesser I1 aufweist, der um mindestens 10%, vorzugsweise mehr als 15% oder mehr größer ist als der Abstand Io der gegenüberliegenden Rohrseitenwände, Dadurch wird eine Fläche für die Verlötung zur Verfügung gestellt, die zu einer deutlichen Stabilitätssteigerung führt.It when the pipe wall sheet has a diameter I1 which is greater by at least 10%, preferably more than 15% or more greater than the distance Io of the opposite pipe side walls, Thus, an area for the soldering is provided, which is a significant increase in stability leads.
Auch ist es zweckmäßig, wenn die Öffnungen des Sammelkastens die gleiche Kontur aufweisen, wie die Kontur des Rohrs. Dadurch weist die Öffnung ebenso eine etwa knochenförmige Kontur auf, mit einem länglichen Mittelteil und kreisförmigen Endbereichen.It is also expedient if the openings of the collecting tank have the same contour as the contour of the pipe. As a result, the opening also has an approximately bony contour on, with an elongated central portion and circular end portions.
Vorteilhaft ist es, wenn zwei Sammelkästen vorgesehen sind, wobei jedes Rohrende in jeweils eine Öffnung einer der beiden Sammelkästen eingreift. Alternativ ist es vorteilhaft, wenn ein Sammelkasten vorgesehen ist, wobei die Rohre derart gebogen ausgeführt sind, dass jedes Rohrende eines Rohrs in jeweils eine Öffnung des einen Sammelkastens eingreift.It is advantageous if two manifolds are provided, each tube end engages in each case an opening of one of the two headers. Alternatively, it is advantageous if a collecting box is provided, wherein the tubes are designed bent such that each tube end of a tube engages in each case an opening of a collecting tank.
Zur Verbesserung der Rohr-Öffnungsverbindung ist es vorteilhaft, wenn die Öffnungen des Sammelkastens oder der Sammelkästen einen hochgestellten Rand als Durchzug aufweisen, welcher nach innen in den Sammelkästen oder nach außen vom Sammelkasten weg gerichtet ist. Dadurch wird die verlötbare Fläche vergrößert, was wiederum die Stabilität der Verbindung zwischen Rohr und Öffnung verbessert.To improve the pipe-opening connection, it is advantageous if the openings of the collecting tank or the collecting tanks have a raised edge as a passage, which is directed inwards in the collecting tanks or outwardly from the collecting box. As a result, the solderable surface is increased, which in turn improves the stability of the connection between the pipe and opening.
Besonders vorteilhaft ist es, wenn die Rohrseitenwände eines Rohrs im Wesentlichen parallel zueinander angeordnet sind. Dies führt zu einer verbesserte Herstellbarkeit, weil die Kontur gut kalibrierbar ist.It when the tube side walls of a tube are arranged substantially parallel to each other is particularly advantageous. This leads to an improved manufacturability, because the contour is well calibrated.
Auch ist es zweckmäßig, wenn der Sammelkasten einem Rohrboden und einen Kastendeckel aufweist, wobei die Öffnungen in dem Rohrboden eingebracht sind.It is also expedient if the collecting box has a tube bottom and a box lid, wherein the openings are made in the tubesheet.
Vorteilhafte Weiterbildungen der vorliegenden Erfindung sind in den Unteransprüchen und der nachfolgenden Figurenbeschreibung beschrieben.Advantageous developments of the present invention are described in the subclaims and the following description of the figures.

Dabei ist es bevorzugt, wenn die Länge L1 der Öffnung 20 kleiner oder gleich der Länge der Öffnung Lo nach dem Stand der Technik ist, so dass die Querschnittsfläche der Öffnung 20 größer oder gleich der Querschnittsfläche des Rohrs 10 ist.It is preferred if the length L1 of the
Die gezeigte Öffnung weist die dargestellte Kontur auf, wobei das verwendete Rohr die gleiche Kontur aufweist, wie die Kontur der Öffnung. Dadurch ergibt sich eine größere Anlagefläche zwischen Öffnung und Rohr, so dass beim Verlöten eine größere Fläche miteinander verbunden wird und damit eine stabilere Verbindung erzeugt wird. Die Rohre 33, 42 weisen dabei eine Breitseite mit der Länge L1 mit gegenüberliegenden Rohrseitenwänden und zwei endseitigen Schmalseiten mit der Breite Io mit jeweils einem Rohrwandbogen auf, wobei der Rohrwandbogen einen Durchmesser I1 aufweist, der größer ist als der Abstand Io der gegenüberliegenden Rohrseitenwände. Der Rohrwandbogen weist dabei eine kreissegmentartige Kontur auf. Dabei weist der Rohrwandbogen einen Durchmesser I1 auf, der um 10%, vorzugsweise um 15% oder mehr größer oder gleich ist als der Abstand Io der gegenüberliegenden Rohrseitenwände, so dass gilt: I1 ≥ 1,1 * Io oder I1 ≥ 1,15 * Io.The opening shown has the contour shown, wherein the tube used has the same contour as the contour of the opening. This results in a larger contact surface between the opening and the tube, so that when soldering a larger area is connected together and thus a more stable connection is generated. The
Die Rohre erfahren daher an ihren seitlichen Randbereichen, an den Schmalseiten, eine Erweiterung, die bogenförmig, kreisbogenförmig oder kreissegmentförmig ausgebildet ist und die einen Durchmesser aufweist, welcher größer ist als die Breite des Rohrs im mittleren Bereich. Das Rohr wird dadurch etwa knochenförmig erweitert. Dabei kann diese Erweiterung nur am Rohrende vorliegen, welches in die Öffnung eingesteckt wird oder alternativ kann die Erweiterung über die gesamte Länge des Rohrs vorliegen.The tubes therefore experience at their lateral edge regions, on the narrow sides, an extension which is arc-shaped, circular arc-shaped or circular segment-shaped and which has a diameter which is greater than the width of the tube in the central region. The tube is thereby extended approximately bone-shaped. This extension can be present only at the end of the pipe, which in the opening or, alternatively, the extension may be over the entire length of the tube.
