Description

Die vorliegende Erfindung betrifft ein Turbulenzblech für einen Wärmetauscher gemäß dem Oberbegriff des Anspruchs 1.The The present invention relates to a turbulence plate for a heat exchangers according to the generic term of claim 1.

Turbulenzbleche für Wärmetauscher weisen oftmals eine gewellte, insbesondere eine die Oberfläche vergrößernde Struktur auf. Die vergrößerte Oberfläche soll einen verbesserten Wärmeaustausch, das heißt eine verbesserte Wärmeübertragung, ermöglichen. Die beispielsweise gewellte Form derartiger Turbulenzbleche wird üblicherweise mittels eines Walzvorganges hergestellt, bei welchem ein Blech zwischen zwei profilierten Walzen hindurchläuft und während des Hindurchlaufens aufgrund der Profilierung der beiden Walzen umgeformt wird. Ein anderes gängiges Verfahren zum Herstellen derartiger Turbulenzbleche ist ein Prägen mittels eines sogenannten Monostempels, welcher in eine zugehörige Matrize eingedrückt wird. Aufgrund der Ausbildung des Monostempels wird dabei jedoch je Stempelvorgang lediglich ein Wellenberg bzw. ein Wellental in das umzuformende bzw. herzustellende Turbulenzblech eingebracht, so dass ein derartiges Herstellungsverfahren zeit- und kostenintensiv ist.turbulence plates for heat exchangers often have a corrugated, in particular a surface-enlarging structure on. The enlarged surface should an improved heat exchange, this means an improved heat transfer, enable. The example corrugated shape of such turbulence sheets is usually produced by means of a rolling process in which a metal sheet between passing through two profiled rolls and while passing through the profiling of the two rolls is formed. Another common procedure for producing such turbulence sheets embossing means a so-called Monostempels, which in an associated matrix pressed becomes. Due to the formation of Monostempels is doing, however each stamping process only a wave crest or a wave trough in the turbulence sheet to be formed or produced is introduced, so that such a manufacturing process is time consuming and costly is.

Die vorliegende Erfindung beschäftigt sich mit dem Problem, für ein Turbulenzblech der gattungsgemäßen Art, eine verbesserte Ausführungsform anzugeben, welche insbesondere eine kostengünstige Herstellung derartiger Turbulenzbleche ermöglicht.The present invention employs dealing with the problem, for a turbulence sheet of the generic type, an improved embodiment indicate, in particular, a cost-effective production of such Turbulence sheets allows.

Advantageous embodiments are the subject of the dependent Claims.

Die Erfindung beruht auf dem allgemeinen Gedanken, ein Turbulenzblech für einen Wärmetauscher nicht mehr mittels eines Monostempels oder eines Walzverfahrens herzustellen, sondern vielmehr mittels eines aus der Automobilindustrie gängigen Tiefziehverfahrens, wobei in einem einzigen Tiefziehvorgang eine Vielzahl von parallel nebeneinander angeordneten Wellentäler und Wellenberge in das umzuformende Turbulenzblech eingebracht werden können, so dass sich durch das erfindungsgemäße Tiefziehen der Turbulenzbleche diese schneller und insbesondere kostengünstiger herstellen lassen. Unter dem Begriff „Ziehen” versteht man das Umformen eines Blechzuschnittes mittels Zugdruck, wobei ein Hohlkörper entsteht, der einseitig geöffnet ist. Generell lassen sich durch ein derartiges Tiefziehen die Turbulenzbleche besonders wirtschaftlich herstellen.The The invention is based on the general idea of a turbulence plate for one heat exchangers no longer using a monostrand or a rolling process but rather by means of one from the automotive industry common thermoforming process, wherein in a single deep drawing process a plurality of parallel juxtaposed troughs and wave crests in the umformormende turbulence plate can be introduced, so that through the Deep drawing according to the invention the turbulence sheets this faster and more cost-effective let produce. The term "pulling" means the forming of a Sheet metal blank by means of tensile pressure, whereby a hollow body is formed, the one-sided opened is. In general, can be by such a deep drawing the turbulence sheets produce particularly economically.

Bei einer vorteilhaften Weiterbildung der erfindungsgemäßen Lösung, weist das Turbulenzblech aus einer Ebene desselben herausgestanzte und herausgeformte Stege auf. Diese Stege sind dabei in ihrer Gesamtheit in der Art von parallel versetzten Wellentäler und Wellenberge angeordnet und dienen einerseits zur Aussteifung des Turbulenzbleches und andererseits zu einer Verbesserung der Wärmeübertragung. Die Stege können dabei in einem einzigen Arbeitsschritt sowohl gestanzt als anschließend auch geformt werden. Hierzu sind an einem entsprechenden Tiefziehwerkzeug bzw. an einer Matrize und einem Stempel desselben entsprechende Schneid- und Umformkonturen vorgesehen.at an advantageous embodiment of the solution according to the invention, has the turbulence plate punched out of a plane of the same and shaped webs on. These webs are in their entirety arranged in the manner of parallel wave troughs and wave crests and serve on the one hand to stiffen the turbulence plate and on the other to improve the heat transfer. The webs can both punched in a single step and then also shaped become. For this purpose, on a corresponding thermoforming tool or on a die and a stamp of the same cutting and Forming contours provided.

Entsprechend den 1–3, sind verschiedene Verfahrensschritte zum erfindungsgemäßen Tiefziehen eines Turbulenzbleches 1 dargestellt. Ein derartiges Turbulenzblech 1 wird beispielsweise bei einem Wärmetauscher eingesetzt, um eine möglichst große Oberfläche für eine optimale Wärmeübertragung, das heißt einen optimalen Wärmeaustausch sowie eine optimale Verwirbelung des Fluides zu erzeugen. Üblicherweise wurden derartige Turbulenzbleche 1 bisher mittels zweier gegeneinander laufender und profilierter Walzen verformt oder mittels eines sogenannten Monostempels, welcher je Stempelvorgang einen Wellenberg 5 bzw. ein Wellental 6 in das noch unverformte Turbulenzblech 1 eingedrückt hat. Mit dem erfindungsgemäßen Tiefziehverfahren kommt ein Tiefziehwerkzeug 2 mit einem Stempel 3 und einer zugehörigen Matrize 4 zum Einsatz, wobei im Stempel 3 bzw. in der Matrize 4 eine Vielzahl von Wellenbergen 5 und Wellentälern 6 nebeneinander angeordnet sind. Darüber hinaus können in dem erfindungsgemäßen Tiefziehwerkzeug 2 nicht gezeigte Schneidkanten vorgesehen sein, welche beim Tiefziehvorgang aus einer Ebene des Turbulenzbleches 1 herausgestanzte und herausgeformte Stege 7 (vgl. 5) erzeugen. Diese Stege 7 erhöhen die Turbulenzen eines durchströmenden Fluides und sorgen dadurch für eine besonders gute Durchmischung des Fluides.According to the 1 - 3 , Are different process steps for deep-drawing a turbulence sheet according to the invention 1 shown. Such a turbulence plate 1 is used, for example, in a heat exchanger in order to produce as large a surface as possible for optimal heat transfer, that is to say optimal heat exchange and optimal turbulence of the fluid. Usually, such turbulence sheets have been used 1 previously deformed by means of two mutually running and profiled rollers or with A so-called Monostempels, which ever stamping a wave crest 5 or a wave trough 6 in the still undeformed turbulence sheet 1 has impressed. With the deep-drawing process according to the invention, a deep-drawing tool is used 2 with a stamp 3 and an associated template 4 used, in the stamp 3 or in the die 4 a variety of wave crests 5 and troughs 6 are arranged side by side. In addition, in the deep-drawing tool according to the invention 2 Cutting edges, not shown, may be provided, which in the deep drawing process from a plane of the turbulence plate 1 punched out and shaped webs 7 (see. 5 ) produce. These bridges 7 increase the turbulence of a flowing fluid and thus ensure a particularly good mixing of the fluid.

Betrachtet man die 5, so fällt auf, dass das Turbulenzblech 1 eine rechteckigwellige Struktur mit parallel zueinander verlaufenden Wellenbergen 5 und Wellentälern 6 aufweist, wobei die Gesamtheit der Stege 7 als parallel zum eigentlichen Wellenberg 5 verschobener Wellenberg 5' angesehen werden kann.Looking at the 5 , it stands out that the turbulence sheet 1 a rectangular wave structure with parallel wave crests 5 and troughs 6 having, wherein the entirety of the webs 7 as parallel to the actual wave mountain 5 shifted wave mountain 5 ' can be viewed.
