Abstract
Die Erfindung betrifft einen Strömungskanal für einen Wärmeaustauscher, in dem sich turbulenzerzeugende Erhebungen (1) befinden, die eine Mantelfläche (10) und eine Verbindungsfläche (11) aufweisen, wobei wenigstens einige Erhebungen (1) entweder in einer Wand (4) des Strömungskanals (3) ausgebildet sind und sich an der gegenüberliegenden Wand (5) desselben Strömungskanals (3) abstützen und damit verbunden sind oder in beiden Wänden (4, 5) ausgebildet sind und sich gegenseitig abstützen und miteinander verbunden sind. Die Kühlleistung wird angehoben, wenn die turbulenzerzeugenden Erhebungen (1) erfindungsgemäß mit in den Strömungskanal (3) gerichteten Vorsprüngen (2) bzw. feinen Strukturen versehen sind, die die Ausbildung von Turbulenzen in den Strömungskanal (3) durchströmenden Medium unterstützen.The invention relates to a flow channel for a heat exchanger, in which turbulence-generating elevations (1) are located, which have a lateral surface (10) and a connection surface (11), wherein at least some elevations (1) either in a wall (4) of the flow channel ( 3) are formed and are supported on the opposite wall (5) of the same flow channel (3) and connected thereto or in both walls (4, 5) are formed and are mutually supported and interconnected. The cooling capacity is raised when the turbulence-generating elevations (1) according to the invention are provided with projections (2) or fine structures directed into the flow channel (3), which support the formation of turbulence in the medium flowing through the flow channel (3).
Description
Die Erfindung betrifft einen Strömungskanal für einen Wärmeaustauscher, in dem sich turbulenzerzeugende Erhebungen befinden, die eine Mantelfläche und eine Verbindungsfläche aufweisen, wobei wenigstens einige Erhebungen entweder in einer Wand des Strömungskanals ausgebildet sind und sich an der gegenüberliegenden Wand desselben Strömungskanals abstützen und damit verbunden sind oder in beiden Wänden ausgebildet sind, sich gegenseitig abstützen und miteinander verbunden sind.The The invention relates to a flow channel for a Heat exchanger, in which turbulence-generating elevations are, which has a lateral surface and a connection surface have at least some elevations either in a wall of the flow channel are formed and on the opposite wall of the same flow channel support and are connected or formed in both walls, each other support and connected to each other.

Turbulenzerzeugende Erhebungen in Strömungskanälen dienen, wie der Begriff bereits sagt, der Erzeugung von Turbulenzen im den Strömungskanal durchströmenden Medium, mit dem Ziel, die Effizienz des Wärmeaustausches mit dem im benachbarten Strömungskanal strömenden Medium anzuheben. Darüber hinaus tragen diese Erhebungen zur Stabilität des Wärmeaustauschers bei, da sie in der Regel metallisch mit den Wänden verbunden sind.Vortex generators Serve elevations in flow channels, As the term already implies, the generation of turbulence in the flow channel flowing through Medium, with the aim of the efficiency of heat exchange with that in the neighboring flow channel flowing Medium to lift. About that In addition, these surveys contribute to the stability of the heat exchanger, since they usually metallically connected to the walls.

Hier setzt die vorliegende Erfindung ein, die die Aufgabe zu lösen hat, Strömungskanäle mit turbulenzerzeugenden Erhebungen zur Verfügung zu stellen, die bei Ausrüstung eines Wärmeaustauschers mit solchen Strömungskanälen eine höhere Kühlleistung versprechen.Here implements the present invention which has the object to solve Flow channels with turbulence-generating Surveys available to put at equipment a heat exchanger with such flow channels one higher cooling capacity promise.
Die erfindungsgemäße Lösung der Aufgabe wird mit dem Kennzeichen des Anspruchs 1 erreicht. Die Vorsprünge oder feinen Strukturen an den turbulenzerzeugenden Erhebungen führen zu erhöhten Turbulenzen im Medium und damit zu einer höheren Kühlleistung. Der Einsatz von Lamellen, die, wie erwähnt, oft zu Problemen bezüglich der Herstellung des geforderten Reinheitsgrades führen, kann in vielen Fällen durch die Erfindung vermieden werden.The inventive solution of The object is achieved with the characterizing part of claim 1. The projections or fine structures at the turbulence-generating elevations lead to increased turbulence in the medium and thus to a higher cooling capacity. The use of lamellae, which, as mentioned, often causes problems regarding the Producing the required degree of purity can, in many cases, by the invention can be avoided.
Obwohl es in vielfältigen Ausführungen zum Stand der Technik gehört, wärmetauschende Oberflächen mit feinen Strukturen zu versehen oder mit einer bestimmten Rauhigkeit auszubilden, um die Effizienz des Wärmetausches zu beeinflussen, handelt es sich vorliegend um eine Erfindung, weil der Gedanke, die feinen Strukturen nur an den turbulenzerzeugenden Erhebungen vorzusehen, durch diesen Stand der Technik nicht nahegelegt sein kann, zumal die Art und Weise der Herstellung der Vorsprünge bzw. der feinen Strukturen an den turbulenzerzeugenden Erhebungen bei der Erfindung anders erfolgt als im Stand der Technik. Im Stand der Technik wird gewöhnlich das gesamte Blechband mit einer Rauhigkeit versehen bevor die Herstellung der Wärmetauscherplatten selbst durchgeführt wird.Even though it in diverse versions belongs to the state of the art, heat exchanging surfaces to be provided with fine structures or with a certain roughness to influence the efficiency of the heat exchange, this is an invention because the idea the fine structures only at the turbulence generating elevations provide, not be suggested by this prior art can, especially the way the production of the projections or the fine structures at the turbulence generating elevations at the invention takes place differently than in the prior art. In the state The technique becomes ordinary the entire sheet metal strip provided with a roughness before the production the heat exchanger plates even done becomes.
Die erfindungsgemäßen feinen Strukturen an den turbulenzerzeugenden Erhebungen werden in das Präge – bzw. Umformwerkzeug eingearbeitet, so dass sie gleichzeitig mit der Herstellung der Wärmetauscherplatten bzw. der Wände des Strömungskanals entstehen. Die Wärmetauscherplatten werden vorzugsweise aus relativ dünnen Aluminiumblechen hergestellt. Die Form der Vorsprünge bzw. der feinen Strukturen, ihre Anordnung und Anzahl kann äußerst vielfältig sein und hängt vom vorgesehenen Anwendungsfall ab. Ferner selbstverständlich auch von der Anordnung und Form der turbulenzerzeugenden Erhebungen selbst. Diese können eine langgestreckte Form aufweisen, sie können kreisrund sein, letztlich können sie beliebige, zweckmäßige Formen besitzen.The fine according to the invention Structures at the turbulence generating elevations are incorporated into the Embossing or forming tool incorporated so that they simultaneously with the production of the heat exchanger plates or the walls of the flow channel arise. The heat exchanger plates are preferably made of relatively thin aluminum sheets. The shape of the projections or the fine structures, their arrangement and number can be extremely diverse and hang from the intended use case. Furthermore, of course, too of the arrangement and shape of the turbulence generating elevations themselves. these can have an elongated shape, they can be circular, ultimately they can any convenient forms have.

Wenigstens einige Strömungskanäle des Wärmeaustauschers weisen die beschriebenen und gezeigten Merkmale auf. Ausdrücklich können das entweder alle Strömungskanäle des Wärmeaustauschers sein oder bespielsweise nur diejenigen für ein Medium. Diejenigen für das andere Medium können durchaus anders ausgebildet, beispielsweise mit Lamellen belegt sein.At least some flow channels of the heat exchanger have the features described and shown. Expressly, either all flow channels of the heat exchanger be or record only those for a medium. Those for the other Medium can certainly designed differently, for example, be occupied with slats.
