Der
Wärmetauscher
ist aus der deutschen Patentanmeldung
Die Aufgabe der Erfindung besteht in der Bereitstellung eines Wärmetauschers dessen Herstellung vereinfacht ist.The The object of the invention is to provide a heat exchanger its manufacture is simplified.
Diese Aufgabe wird bei einem Wärmetauscher gemäß dem Oberbegriff des Anspruchs 1 erfindungsgemäß durch die Merkmale in seinem kennzeichnenden Teil gelöst. Ein alternativer Lösungsvorschlag besitzt die kennzeichnenden Merkmale des Anspruchs 2.These Task is at a heat exchanger according to the generic term of claim 1 according to the invention by the features are solved in its characterizing part. An alternative solution has the characterizing features of claim 2.
Es ist vorgesehen, dass das als Seitenteil dienende Rohr nicht durchströmt ist und aus demselben endlosen Rohr stammt wie die Flachrohre.It is provided that the pipe serving as a side part is not flowed through and comes from the same endless tube as the flat tubes.
Mit der Formulierung „aus demselben endlosen Rohr stammt" soll zum Ausdruck gebracht werden, dass zunächst kein Unterschied zwischen den Flachrohren und dem Rohr besteht. Bei dem endlosen Rohr kann es sich um ein Stück aus endlosem Blechband hergestellter beispielsweise geschweißter Flachrohre handeln oder auch um ein Stück aus mittels Strangpressverfahren hergestellter Mehrkammer-Flachrohre.With the wording "out the same endless tube be expressed that initially no difference between consists of the flat tubes and the tube. In the endless tube can it is a piece made of endless sheet metal, for example, welded flat tubes act or even a piece made by extrusion multi-chamber flat tubes.
Die alternative Lösung sieht vor, dass das als Seitenteil dienende Rohr nicht durchströmt ist und aus einem anderen endlosen Rohr stammt als die Flachrohre. Dadurch soll zum Ausdruck kommen, dass ein Unterschied zwischen den Flachrohren und dem Rohr besteht, beispielsweise ein Unterschied der Wanddicke. Die Wanddicke der Flachrohre kann z. B. kleiner sein als die der Rohre. Durch diese Alternative können wunschgemäß als Seitenteil dienende Rohre zum Einsatz gelangen, die zu einer höheren Stabilität des Wärmetauschers führen. Beispielsweise kann es sich bei dem Rohr um ein stranggepresstes Mehrkammerrohr handeln, wie sie beispielsweise beim Bau von Kondensatoren für Klimaanlagen Verwendung finden, das von einem endlosen Rohr zugeschnitten wurde. Bei den Flachrohren kann es sich um solche handeln, die aus einem endlosen Blechstreifen zum endlosen Flachrohr geformt und auf eine einheitliche Länge zugeschnitten wurden. Das als Seitenteil dienende Rohr stammt also gemäß der Alternative von einem anderen endlosen Rohr als die Flachrohre, bzw. es handelt sich bei dem Rohr um ein Stück aus einem anderen endlosen Flachrohr.The alternative solution provides that the pipe serving as a side part is not flowed through and out another endless tube comes as the flat tubes. This should express that a difference between the flat tubes and the tube, for example a difference in wall thickness. The wall thickness of the flat tubes can z. B. be smaller than that of Tube. Through this alternative can as desired as a side part serving pipes leading to a higher stability of the heat exchanger to lead. For example, the tube may be an extruded one Multi-chamber tube act, as for example in the construction of capacitors for air conditioners Find use that was cut from an endless tube. The flat tubes may be those that consist of a endless sheet metal strip formed into an endless flat tube and on a uniform Length tailored were. The serving as a side tube thus comes according to the alternative from another endless tube than the flat tubes, or it acts at the pipe a piece from another endless flat tube.
Durch diese einfachen Vorschläge können die Herstellungskosten für den Wärmetauscher signifikant reduziert werden, ohne auf die Vorteile von Seitenteilen bezüglich Stabilität usw. zu verzichten. Im Fertigungsprozess braucht nicht darauf geachtet zu werden, welches der Flachrohre als das als Seitenteil dienende Rohr zum Einsatz kommt. Spezielle Werkzeuge zur Herstellung sonst üblicher Seitenteile sind nicht notwendig.By these simple suggestions can they Production costs for the heat exchanger be significantly reduced without the benefits of side panels in terms of stability etc. to give up. In the manufacturing process does not need to pay attention to be which of the flat tubes as serving as the side part Tube is used. Special tools for the production of otherwise usual Side parts are not necessary.
Nach einem Aspekt ist vorgesehen, dass das Rohr die gleiche Länge, den gleichen Querschnitt, die gleiche Kühlnetztiefe und natürlich die gleiche Wanddicke aufweist wie die Flachrohre.To In one aspect, it is provided that the tube is the same length, the same cross section, the same cooling mesh depth and of course the Same wall thickness as the flat tubes.
Nach einem anderen Aspekt ist vorgesehen, dass das Rohr identisch mit den Flachrohren ist. Das heißt im vorliegenden Zusammenhang und im Unterschied zum vorstehenden Aspekt, dass das Rohr zusätzlich auch einen Inneneinsatz aufweisen kann, falls die Flachrohre Inneneinsätze aufweisen oder dass das Rohr mit Sicken versehene Breitseiten aufweisen kann, falls die Flachrohre solche Sicken aufweisen.To In another aspect it is provided that the tube is identical to the flat tubes is. This means in the present context and unlike the above Aspect that the pipe in addition may also have an inner insert, if the flat tubes have inner inserts or that the tube may have beaded broadsides, if the flat tubes have such beads.
Nach einem anderen Aspekt liegt im Sinne des vorliegenden Vorschlags auch dann noch der gleiche Querschnitt des Rohres vor, wenn das als Seitenteil dienende Rohr beispielsweise in Längsrichtung laufende Sicken aufweist. Diese Sicken können eingebracht werden, wenn die Rohre die Fertigungslinie verlassen haben bzw. vom endlosen Rohr bereits abgetrennt worden sind. In dem Fall ist das Rohr dann nicht mehr identisch mit den Flachrohren. Die Sicken können sich aber auch dadurch erzeugt werden, dass mittels Löthilfsvorrichtungen die Rohre auf in Längsrichtung laufenden Linien zusammengedrückt werden.To Another aspect is within the meaning of this proposal even then the same cross-section of the pipe before, if the serving as a side tube, for example, longitudinally running beads having. These beads can be introduced when the pipes leave the production line have or have already been separated from the endless tube. In In this case, the pipe is then no longer identical to the flat pipes. The Beading can But also be generated by the fact that by means of Löthilfsvorrichtungen the tubes in the longitudinal direction compressed lines become.
Schließlich kann vorgesehen werden, dass das Rohr an den Sammelkästen oder an den Rohrböden entweder befestigt ist oder nicht befestigt ist.Finally, can be provided that the pipe to the headers or to the tube plates either is attached or not attached.
Es kann auch vorgesehen werden, dass sich die Befestigungspunkte im Betrieb des Wärmetauschers entweder lösen können oder auch nicht lösen können. Durch sich lösende Befestigungspunkte kann das Verhalten der Flachrohre bei Erwärmung und Abkühlung positiv beeinflusst werden, und es kommt seltener zu Spannungsrissen.It can also be provided that the attachment points can either solve during operation of the heat exchanger or can not solve. By solving attachment points, the behavior of the flat tubes when heated and cooling are positively influenced, and it is less likely to stress cracks.
Im Vergleich zu den bekannten massiven Seitenteilen stellt sich bezüglich des durch Temperaturwechsel bewirkten Ausdehnungsverhaltens der Vorteil ein, dass die als Rohr ausgebildeten Seitenteile ein ähnliches oder sogar das gleiche Ausdehnungsverhalten haben wie die Flachrohre.in the Compared to the known massive side parts arises with respect to the Thermal expansion caused by temperature change the advantage in that the pipe parts designed as a similar part or even have the same expansion behavior as the flat tubes.
Bei dem Wärmetauscher kann es sich beispielsweise um einen Kühlflüssigkeitskühler oder um einen Ladeluftkühler handeln, dessen Kühlrippen von Kühlluft durchströmt werden, ohne dass damit andere Verwendungen ausgeschlossen werden sollen.at the heat exchanger it may be, for example, a coolant radiator or an intercooler, its cooling fins of cooling air flows through without excluding other uses should.
Im Folgenden wird die Erfindung in einem Ausführungsbeispiel beschrieben. Dazu wird Bezug auf die beiliegenden Zeichnungen genommen.in the The invention will be described below in one embodiment. Reference is made to the accompanying drawings.
