Plattenförmiger WärmeaustauscherPlate-shaped heat exchanger

Die Erfindung bezieht sich auf einen plattenförmigen Wärmeaustauscher, insbesondere einen Wärmeaustauscher für Flüssigkeiten mit hoher Yiskosität.The invention relates to a plate-shaped heat exchanger, in particular a heat exchanger for liquids with high viscosity.

Im allgemeinen weist ein plattenförmiger Wärmeaustauscher eine Vielzahl von nebeneinander angeordneten Platten auf, welche sich abwechselnde Zwischenräume für zwei Medien bilden, zwischen denen Wärmeübertragung stattfindet.In general, a plate-shaped heat exchanger has a plurality of plates arranged next to one another, which create alternating spaces for two media, between which heat transfer takes place.

Bei den herkömmlichen Wärmeaustauschern dieser Art wird bei Verwendung von Flüssigkeit mit hoher Viskosität, wie z.B. bei der Kühlung eines Schmieröls bei großen Motoren, die einem Zwischenraum zwischen den benachbarten Platten durch eine Flüssigkeitsöffnung an den entsprechenden Stellen jeder Platte zugeführt wird, ein Ausbreiten über die gesamte Breite der Wärmeübertragungsfläche der Platte aufgrund hoher Viskosität verhindert, was eine ungleiche Strömung bewirkt.In conventional heat exchangers of this type, Using a liquid with a high viscosity, such as cooling a lubricating oil in a large engine that has a Space between the adjacent plates through a liquid opening at the corresponding locations on each plate spreading over the entire width of the heat transfer surface of the plate due to high viscosity prevents what causes uneven flow.

In anderen Worten, die in den Zwischenraum zwischen den benachbarten Platten durch die Flüssigkeitsöffnung einfließende Flüssigkeit fließt mit zunehmender Entfernung von der öffnung langsamer, und je höher ihre Viskosität ist, um so stärker weicht ihre Geschwindigkeit hinsichtlich der QuerrichtungIn other words, those in the space between the neighboring ones Plates flowing in through the liquid opening flows with increasing distance from the opening slower, and the higher their viscosity, the more their speed deviates with respect to the transverse direction

der Platte ab, wodurch ein Abweichen der Fl.üsaigke.itsströmung leicht hervorgerufen werden kann und daher ein offensichltich toter Zwischenraum aufgrund der verringerten Breite der Hauptströmung auftritt.the plate, causing a deviation in the fluid flow can be easily evoked and therefore an obvious one dead space occurs due to the reduced width of the main flow.

Daher erhöht sich die tatsächliche Geschwindigkeit der Flüssigkeit, was eine Druckverminderung bewirkt. Der dadurch entstandene tote Zwischenraum verringert sowohl die Wärmewirkung als auch die Wirksamkeit der Wärmeübertragung.Therefore, the actual velocity of the liquid increases, which causes a pressure reduction. The resulting dead space reduces both the heat effect as well as the effectiveness of the heat transfer.

Aufgabe der Erfindung ist es daher, einen plattenförmigen Wärmeaustauscher zu schaffen, welcher im Besonderen für Flüssigkeiten mit hoher Viskosität geeignet ist und die obenbeschriebenen Nachteile der herkömmlichen plattenförmigen Wärmeaustauscher beseitigt.The object of the invention is therefore to create a plate-shaped heat exchanger which is particularly suitable for liquids with high viscosity is suitable and the above-described disadvantages of the conventional plate-shaped heat exchangers eliminated.

Es ist erfindungsgemäß ein plattenförmiger Wärmeaustauscher mit einer Vielzahl von nebeneinander angeordneten Platten geschaffen, welche sich abwechselnde Zwischenräume für zwei Medien bilden, wobei jede Platte eine Vielzahl von in vertikalen Zwischenräumen angeordneten, sich über die gesamte Breite der Wärmeübertragungsfläche erstreckenden Trennuten aufweist sowie eine Vielzahl von quer verlaufenden, in der Fläche zwischen den Trennuten gebildeten Rillen.According to the invention, it is a plate-shaped heat exchanger created with a plurality of panels arranged side by side, which alternate spaces for two Media form, with each plate a plurality of vertically spaced, extending across the entire width the heat transfer surface extending separating grooves and a plurality of transverse, in the surface grooves formed between the parting grooves.

Nach der Erfindung kann vorteilhafterweise die gesamte Plattenoberfläche im höchsten Maße als wirksame Wärmeübertragungsfläche verwendet werden, wobei die Wärmeübertragung des Wärmeaustauschers mit geringerem Druckverlust zunimmt. Aus diesem Grund verwendet der erfindungsgemäße plattenförmige Wärmeaustauscher Flüssigkeiten mit hoher Viskosität.According to the invention, the entire plate surface can advantageously can be used to the greatest extent as an effective heat transfer surface, the heat transfer of the heat exchanger increases with lower pressure loss. For this reason, the plate-shaped heat exchanger according to the invention is used High viscosity liquids.

Weitere Merkmale der Erfindung werden anhand der folgenden Beschreibung sowie der Zeichnungen näher erläutert.Further features of the invention are explained in more detail with reference to the following description and the drawings.

In den Zeichnungen zeigt:In the drawings shows:

Fig. 1 eine Vorderansicht einer Platte des erfindungsgemäßen plattenförmigen Wärmeaustauschers; Fig. 1 is a front view of a plate of the invention plate-shaped heat exchanger;

Fig. 2 einen Schnitt entlang der Linie II-II nach Fig. 1; undFig. 2 is a section along the line II-II according to Fig. 1; and

Fig. 3 einen Teil einer vergrößerten perspektivischen Ansicht mehrerer Platten nach Fig. 1.3 shows a part of an enlarged perspective View of several plates according to FIG. 1.

Nach den Zeichnungen weist eine Platte 1, durch welche über Medien Wärmeübertragung stattfindet, eine Vielzahl von in vertikalen Zwischenräumen angeordneten, quer verlaufenden Trennuten 2 auf, welche im wesentlichen über die gesamte Wärmeübertragungsf-lache gebildet sind, und eine Vielzahl von quer angeordneten, vertikal verlaufenden Rillen 3, welche zwischen den Trennuten gebildet sind. Diese Rillen 5 dienen der Vergrößerung der wirksamen Wärmeubertragungsflache.According to the drawings, a plate 1, through which about Media heat transfer takes place, a multitude of vertically spaced, transverse Separating grooves 2, which essentially over the entire Heat transfer surface are formed, and a variety of transversely arranged, vertically extending grooves 3 which are formed between the separating grooves. These grooves 5 are used the enlargement of the effective heat transfer area.

Eine Vielzahl von Platten 1 wird sich gegenüberliegend zusammengesetzt zur EüLdung sich abwechselnder Zwischenräume 4, 5 für die beiden Medien, zwischen welchen Wärmeübertragung stattfindet. 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 multiplicity of plates 1 are put together opposite one another to form alternating spaces 4, 5 for the two media, between which heat transfer takes place. Usually, these spaces 4 and 5 are delimited on the circumference by sealing elements (not shown) which lie between the adjacent plates and run along the inside of the outer edge of the plate surfaces.

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 on the corresponding ones Set up, with openings 6 and 7 for one of the two Media are only in communication with the space 4, whereas the remaining openings 8 and 9 for the other medium only are in communication with the space 5. The two spaces in between on opposite sides of the space to which one of the two media is fed the other medium on.

Angenommen, es wird z.B. ein flüssiges Medium mit hoher Viskosität durch die Öffnung 6 geführt, so sieht man, daß dieses flüssige Medium in den Zwischenraum 4 durch die Öffnung 6 eintritt und an der Wärmeübertragungsfläche der Platte 1 abwärts fließt. Nun nimmt das Medium aufgrund der Rillen 3, welche sich entlang der Strömungsrichtung des die Wärmeübertragung steigernden Mediums erstrecken, eine laminare Strömung an. Erreicht das Medium die Trennut 2, so verteilt es sich quer entlang der Trennut, d.h. e ntlang der Breite der Wärmeübertragungsfläche der Platte 1.Suppose, for example, that it is a liquid medium with high viscosity guided through the opening 6, it can be seen that this liquid medium enters the space 4 through the opening 6 and down on the heat transfer surface of the plate 1 flows. Now the medium takes due to the grooves 3, which extend along the flow direction of the medium increasing the heat transfer, a laminar flow. When the medium reaches the separating groove 2, it is distributed across the separating groove, i.e. along the width of the heat transfer surface of plate 1.

Nach Füllen der Nut 2 breitet es sich über die gesamte Breite der wirksamen Wärmeübertragungsfläche aus. Donach wird obenbeschriebene Folge in dex· gleichen Weise wiederholt, wobei das flüssige Medium die untere nachfolgende Rille 5 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. Then is described above The sequence is repeated in the same way, with the liquid medium following the lower groove 5 and the Reached parting grooves 2 while their average speed is decreasing.
