Abstract
Description
Die Erfindung betrifft Wellrippen mit etwa senkrechten oder leicht geneigten Wellenflanken zwischen flachen Wellenbergen bzw. flachen Wellentälern, die zwischen zwei Flachrohren in einem Wärmetauscher angeordnet sind.The The invention relates to corrugated ribs with approximately vertical or slightly inclined Wave flanks between flat wave crests and shallow troughs, the are arranged between two flat tubes in a heat exchanger.
Solche Wellrippen werden manchmal als „flat top fins" bezeichnet, weil sie im Gegensatz zu anderen Wellrippen etwa ebene (flache) Wellenberge bzw. Wellentäler besitzen. Die angesprochenen anderen Wellrippen haben etwa halbrunde Wellenberge und Wellentäler, wobei die Wellenflanken dort gewöhnlich auch eine etwas größere Neigung aufweisen.Such Corrugated ribs are sometimes referred to as "flat top fins" because they in contrast to other corrugated ribs about flat (flat) wave crests or troughs have. The mentioned other corrugated ribs have about semicircular Wave mountains and troughs, the wave flanks usually there as well a slightly greater inclination exhibit.
Flat top fins werden oft eingesetzt, weil sie bezüglich gut wärmeleitender Lötverbindungen zwischen den Wellenbergen bzw. den Wellentälern und einer angrenzenden Rohrwand als wirksamer angesehen werden als die Wellrippen mit gerundeten Wellenbergen bzw. Wellentälern. Gut wärmeleitende Verbindungen haben selbstverständlich einen bedeutsamen Einfluss auf die Wärmetauscheffizienz zwischen einem in den Rohren strömenden Medium und einem durch die Wellrippe strömenden Medium, welches vorzugsweise Kühlluft ist.Flat Top fins are often used because they have good heat conducting solder joints between the wave crests or troughs and an adjacent one Pipe wall to be considered more effective than the corrugated fins with rounded Wave mountains or troughs. Good heat-conducting Of course, connections have a significant impact on the heat exchange efficiency between a flowing in the pipes Medium and flowing through the corrugated medium, which preferably cooling air is.
Flat top fins haben aufgrund der größeren Steilheit der Wellenflanken, oft stehen die Wellenflanken senkrecht, also sie laufen parallel zueinander, hinsichtlich ihrer Stabilität einige Nachteile. Eine Kraft, die senkrecht zu den Wellenflanken an den Wellenbergen oder den Wellentälern angreift, kann schnell zum Umkippen bzw. zum Einknicken der Wellrippen führen. Dies spielt insbesondere dann eine größere Rolle, wenn man dem Trend nach immer dünneren Wanddicken der Wellrippen folgen möchte.Flat top fins have due to the greater steepness the wave flanks, often the wave flanks are vertical, so they run parallel to each other, some in terms of their stability Disadvantage. A force perpendicular to the ripples on the wave crests or the troughs attacks, can quickly lead to tipping or buckling of the corrugated fins to lead. This is especially important if you follow the trend after ever thinner Wall thicknesses of corrugated ribs would like to follow.
Die Aufgabe der Erfindung besteht darin, die Stabilität von flat top fins zu verbessern. Diese Aufgabe wird erfindungsgemäß durch die Merkmale im Anspruch 1 gelöst.The The object of the invention is the stability of flat to improve top fins. This object is achieved by the features in claim 1 solved.
Es ist vorgesehen, dass in Abständen angeordnete Einschnitte in den Wellenbergen und in den Wellentälern angeordnet sind, wobei die Partie zwischen zwei Einschnitten nach innen eingeknickt ausgebildet ist. Die eingeknickten Partien sorgen für eine größere Stabilität der Wellrippe. Ferner sorgen diese Partien für eine verbesserte Verwirbelung der Kühlluft im Nahbereich der Wellenberge und der Wellentäler und somit für eine bessere Wärmetauscheffizienz.It is provided that in intervals arranged incisions arranged in the wave crests and in the troughs with the game folded in between two incisions is trained. The kinked parts ensure greater stability of the corrugated fin. Furthermore, these games provide for an improved turbulence of the cooling air in the vicinity of the wave crests and the troughs and thus for a better heat exchange efficiency.
Es ist vorgesehen, dass zwei gegenüberliegende Partien an jedem Wellenberg und an jedem Wellental angeordnet sind.It is provided that two opposite Games are arranged on each wave mountain and on each wave trough.
Als Alternative kann allerdings auch vorgesehen werden, die Partien an jedem Wellental und an jedem Wellenberg versetzt zueinander anzuordnen.When Alternative, however, can also be provided, the games at each wave trough and at each wave crest staggered to each other.
In den Wellenflanken sind aus deren Ebene herausgestellte Schnitte angeordnet, die sich über etwa die gesamte Länge der Wellenflanken bzw. über die Höhe der Wellrippen erstrecken, wobei die Wellenflanken zwischen gegenüberliegenden Partien mit oder ohne Schnitte ausgebildet sind.In the wave flanks are cuts made out of their plane arranged over about the entire length the wave edges or over the height of Corrugated ribs extend, wherein the wave flanks between opposite Batches with or without cuts are formed.
Die Länge der Einschnitte ist etwa gleich der Länge der eingeknickten Partien. Deshalb wird das Material in den Partien jedenfalls nicht wesentlich gedehnt, sondern nur umgeformt. Da die Materialdicke lediglich im Bereich von 0,04–0,10mm liegt, können Risse vermieden werden.The Length of Incisions are approximately equal to the length of the folded-in parts. Therefore, the material does not become essential in the games anyway stretched, but only reshaped. Since the material thickness is only in the Range of 0.04-0.10mm lies, can cracks be avoided.
Es hat sich ferner herausgestellt, dass durch die vorgeschlagene Ausbildung der Herstellungsprozess der Wellrippen mittels Walzen positiv beeinflusst wird, weil das Herauslösen der Wellenflanken aus den Zähnen der Walzen unterstützt wird. Die Partien wirken als Abstreifer.It has also been found by the proposed training the production process of corrugated ribs is positively influenced by means of rollers is because the dissolving the wave flanks from the teeth the rollers supported becomes. The games act as scrapers.
Die Erfindung wird anhand von drei beiliegenden Abbildungen erläutert.The The invention will be explained with reference to three accompanying figures.
