Die E/findung bezieht sich auf einen plattenförmigen Wärmeaustauscher mit vertikal angeordneten, im Abstand zueinander liegenden, wellenförmigen Platten für den Wärmeaustausch zwischen zwei Medien, wobei jede vertikale Platte horizontal verlaufende Trennuten aufweist.The invention relates to a plate-shaped heat exchanger with vertically arranged, spaced-apart, wave-shaped plates for heat exchange between two media, each vertical plate having horizontally extending separating grooves.
Ein solcher Wärmeaustauscher ist durch die DE-PS 8 64 560 bekannt. Bei diesem Wärmeaustauscher wird das Wärmeaustauschmedium verwirbelt, so daß eine turbulente Grenzschichtströmung vorliegt; auch sind die Trennuten so geformt, daß ein Wärmeaustauschmittel auf einem schraubenförmigen Weg durch den Wärmetauscher geführt wird.Such a heat exchanger is known from DE-PS 8 64 560. This heat exchanger is the heat exchange medium swirls so that there is a turbulent boundary layer flow; also are the separation grooves are shaped to allow heat exchange means to travel in a helical path through the heat exchanger to be led.
Stand der Technik ist weiterhin ein Dampfkondensator, bei welchem schräg verlaufende Rillen vorhanden sind, welche die Aufgabe einer wirksamen Kondensatableitung haben (DE-OS 27 40 523).The prior art is also a steam condenser in which inclined grooves are present are, which have the task of effective condensate drainage (DE-OS 27 40 523).
Demgegenüber besteht die Aufgabe der vorliegenden Erfindung darin, einen plattenförmigen Wärmeaustauscher der eingangs genannten Art zu schaffen, welcher speziell für Flüssigkeiten mit hoher Viskosität geeignet ist.In contrast, the object of the present invention is to provide a plate-shaped heat exchanger to create of the type mentioned, which is especially suitable for liquids with high viscosity is.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Rillen vertikal zu den Trennuten angeordnet sind und daß die Strömungsrichtung für ein zu kühlendes hochviskoses Medium ebenfalls senkrecht zu den Trennuten verläuft. Hierdurch ergibt sich der Vorteil, daß im Zusammenwirken mit den vertikalen Rillen und den horizontalen Trennuten die gesamte Plattenoberfläche als wirksame Wärmeübertragungsfläche verwendet werden kann, wobei die Wärmeübertragung des Wärmeaustauschers mit geringem Druckverlust zunimmt. Erreicht das Medium eine Trennut, so verteilt es sich quer entlang dieser Trennut, d. h. entlang der Breite der Wärmeübertragungsfläche der Platte. Diese speziell gestaltete Konstruktion des Wärmeaustauschers ist daher eine Anordnung, wie sie für Flüssigkeiten mit hoher Viskosität, beispielsweise bei der Kühlung eines Schmieröls bei großen Motoren besonders anwendbar ist.According to the invention, this object is achieved in that the grooves are arranged vertically to the separating grooves are and that the flow direction for a highly viscous medium to be cooled is also perpendicular to the Separating grooves runs. This has the advantage that in cooperation with the vertical grooves and The horizontal separating grooves use the entire surface of the plate as an effective heat transfer surface can be, wherein the heat transfer of the heat exchanger increases with little pressure loss. If the medium reaches a dividing groove, it is distributed transversely along this dividing groove, i. H. along the width the heat transfer area of the plate. This specially designed construction of the heat exchanger is therefore an arrangement as used for liquids with high viscosity, for example when cooling a Lubricating oil is particularly applicable to large engines.
Die Erfindung wird nachfolgend anhand eines in den Zeichnungen dargestellten Ausführungsbeispiels näher beschrieben. Es zeigt ■The invention is explained in more detail below with the aid of an exemplary embodiment shown in the drawings described. It shows ■
Fig. 1 eine Vorderansicht einer Platte eines Wärmeaustauschers; Fig. 1 is a front view of a plate of a heat exchanger;
Fig. 2 einen Schnitt entlang der Linie H-II nach F i g. 1; undFIG. 2 shows a section along the line H-II according to FIG. 1; and
F i g. 3 einen Teil einer vergrößerten perspektivischen Ansicht mehrerer Platten nach Fig. 1.F i g. 3 is a part of an enlarged perspective view of a plurality of plates according to FIG. 1.
Eine Platte 1 eines Wärmeaustauschers weist eine Vielzahl von in vertikalen Zwischenräumen angeordneten, quer verlaufenden Trennuten 2 auf, welche im wesentlichen über die gesamte Wärmeübertragungsfläche ausgebildet sind, und eine Vielzahl von quer angeordneten, vertikal verlaufenden Rillen 3. welche zwischen den Trennuten ausgerichtet sind. Diese Rillen 3 dienen der Vergrößerung der wirksamen Wärmeübertragungsfläche. A plate 1 of a heat exchanger has a multiplicity of vertically spaced, transverse separating grooves 2, which essentially over the entire heat transfer surface are formed, and a plurality of transversely arranged, vertically extending grooves 3. which between the Separating grooves are aligned. These grooves 3 serve to increase the effective heat transfer area.
Eine Vielzahl von Platten 1 werden sich gegenüberliegend so zusammengesetzt, daß sich abwechselnd Zwischenräume 4, 5 für die beiden Medien, zwischen welchen Wärmeübertragung stattfindet, bilden. Gewöhnlich sind diese Zwischenräume 4 und 5 von Dichtungselementen (nicht dargestellt) am Umfang begrenzt, welche zwischen den benachbarten Platten liegen und entlang der Innenseite des äußeren Randes der Plattenflächen verlaufen.A plurality of plates 1 are assembled opposite one another so that alternating spaces 4, 5 for the two media between which heat transfer takes place. Usually these spaces 4 and 5 of sealing elements (not shown) are limited on the circumference, which lie between the adjacent panels and along the inside of the outer edge of the panel surfaces get lost.
Jede Platte weist öffnungen 6, 7, 8 und 9 an den entsprechenden Stellen auf, wobei die öffnungen 6 und 7 für eines der beiden Medien nur mit dem Zwischenraum 4 in Verbindung stehen, wohingegen die übrigen öffnungen 8 und 9 für das andere Medium nur mit dem Zwischenraum 5 in Verbindung stehen. Die beiden Zwischenräume an sich gegenüberliegenden Seiten des Zwischenraums, welchem eines der beiden Medien zugeführt wird, nehmen das andere Medium auf.Each plate has openings 6, 7, 8 and 9 at the corresponding points, the openings 6 and 7 for one of the two media are only in connection with the intermediate space 4, whereas the others Openings 8 and 9 for the other medium are only connected to the space 5. The two spaces in between on opposite sides of the space to which one of the two media is supplied will record the other medium.
Wird ein flüssiges Medium mit hoher Viskosität durch die öffnung 6 geführt, so tritt dieses flüssige Medium in den Zwischenraum 4 ein und fließt an der Wärmeübertragungsliäche der Platte :l abwärts. Aufgrund der Rillen 3, welche sich entlang der Strömungsrichtung des die Wärmeübertragung steigernden Mediums erstrecken, stellt sich bei dem Medium eine laminare Strömung ein. Erreicht das Medium die Trennut 2, so verteilt es sich quer entlang der Trennut; d. h. entlang der Breite der Wärmeübertragungsfläche der Platte 1.Is made by a liquid medium with high viscosity guided through the opening 6, this liquid medium enters the intermediate space 4 and flows on the heat transfer surface the plate: l downwards. Due to the grooves 3, which extend along the flow direction of the Extending the medium increasing heat transfer, a laminar flow is established in the medium. When the medium reaches the dividing groove 2, it is distributed across the dividing groove; d. H. along the width of the Heat transfer surface of the plate 1.
Nach Füllen der Nut 2 breitet es sich über die gesamte Breite der wirksamen Wärmeübertragungsfläche aus. Danach wird obenbeschriebene Folge in der gleichen Weise wiederholt, wobei das flüssige Medium die untere nachfolgende Rille 3 und die Trennuten 2 erreicht, während sich ihre Durchschnittsgeschwindigkeit verringert.After filling the groove 2, it spreads over the entire width of the effective heat transfer surface the end. Thereafter, the above-described sequence is repeated in the same way, the liquid medium being the lower subsequent groove 3 and the separation grooves 2 reached while their average speed decreased.
