Description

Die Erfindung bezieht sich auf aus Blech gepreßte Wärmeaustauschpl.atten, die paarweise zu Plattenpaketen zusammengestellt werden. An den Rändern werden Gummiringe als Abdiatung eitergelegt, so daß zwischen den einzelnen Platten dünne Hohlräume entstehen, durch die die wärmeaustauschenden Flüssigkeiten, durch jeweils eine Platte getrennt, hindurchgedrikkt <werden. Auch um die in den Ecken, der Platten vorgesehenen Zu- und AbfluBlöcher sind Gummidirhtungen im entsprec'hend@r Anordnung vorgesehen. Die Gummidichtungen liegen in der vertieften (negativen) Seite von eingepreßten Sicken. Außerdem sind noch 'besondere Sicken. in der Fläche der Platten vorgesehen, die zur Führung der Flüssigkeiten dienen. Die Sicken für die Dichtungen, wie auch die Führungsrippen, stellen sich auf der einen Seite des Bleches a'lls Erhöhungen, auf der entgegengesetzten als Vertiefungen. dar. An Stellen, wo sich Sicken und Nuten kreuzen oder sich nahekommen, entstehen große Schwierigkeiten beim Absperren der Fließwege. Es entstehen Lücken, .die beim heutigen Stand der B-lechpr.#ßteohni;k nicht vermieden werden können und dazu zwingen, an den gefährdeten Stellen Brücken od..dgl. anzuschweißen. Das ist ein großer Nachteil insofern, als die Herstellung der Platte verteuert wird, und die Schweißstellen auch mehr oder weniger stark zum Rosten neigen, was besonders für empfindliche Nährflüssigkeiten, wie Milch, Bier, Fruchtsaft u. dgl., .große Nachteile zur Folgehaben kann.The invention relates to heat exchange plates pressed from sheet metal, which are put together in pairs to form plate packs. There are rubber rings on the edges laid on as an abduction, so that there are thin cavities between the individual plates arise through which the heat exchanging liquids, each through a plate separated, thrown through. Also around the ones provided in the corners of the panels Inlet and outlet holes are provided with rubber wires in the appropriate arrangement. The rubber seals are in the recessed (negative) side of the pressed in Beads. There are also special beads. provided in the surface of the panels, which serve to guide the liquids. The beads for the seals, as well the guide ribs, put up on one side of the sheet a'lls elevations, on the opposite as depressions. in places where there are beads and Grooves cross or come close to each other, great difficulties arise when shutting off the flow paths. There are gaps which, given the current state of the B-lechpr. # Ssteohni; k cannot be avoided and force bridges at the endangered areas or the like to be welded on. This is a major disadvantage in that it is manufacturing the plate becomes more expensive, and the welds are also more or less strong for There is a tendency to rust, which is particularly important for sensitive nutrients such as milk, beer, Fruit juice and the like, can have major disadvantages as a consequence.

Diese Schwierigkeiten beseitigt die Erfindung dadurch, daß die Sicken benachbarter Platten konstruktiv derartig ausgebildet sind,, daß die Sicken der einen Platte .mit den Sicken der anderen die Strömungswege für die Flüssigkeiten begrenzen.The invention eliminates these difficulties in that the beads Adjacent panels are constructed in such a way, that the beads of the one plate .with the beads of the other the flow paths for the liquids limit.

Die Erfindung ist in der Zeichnung durch die Abb. i und 2 dargestellt, .und zwar sind in'beiden Platten lediglich die Sicken für die Stromführung mitgezeichnet, die den Strom unterteilenden Sicken der einen Platte (Kanalplatte) sind der besseren Übersichtlichkeit wegen fortgelassen.The invention is illustrated in the drawing by Figs. I and 2, . and only the beads for the current conduction are marked in both plates, the corrugations of one plate (channel plate) dividing the flow are the better ones Omitted for clarity.

In. der Zeichnung ist i der plane Teil der Platte, die ringsherum von einer Nut 2 zur Aufnahme einer Gummidichtung umgeben ist. Diese Dichtungsnut umschließt auchdieZuflußlöchrer, z. B. bei 3. An Stellen, wo der Flüssigkeitsstrom gegen das Inmere i der Platte abgeschlossen sein muß, sind NTerbindungsstücke aus Gummi einge'l'egt, die ebenfalls in Nuten (Sicken) liegen, z. B. bei 4. Diese Nuten können, im Blech natürlich nur dadurch gebildet werden, daß das Blech an beiden Flanken der Nuten 2 hochgepreßt wird. Es entstehen dann die Wülste 5 und 6, zwischen denen dann die vertiefte Nut 2 liegt. Die Kanäle 7-7 werden durch die Sicken 8, 9, io und i i begrenzt, die die Flüssigkeiten zwingen, zickzackförmig über die Platten zuströmen-. Diese Sicken sind nach oben (dem Beschauer zu) erhaben. Wird das Plattenpaket betriebsmäßig zusammengestellt, d. h. legt man z. B. d'ie links gezeichnete Platte über die rechts gezeichnete, so liegt das Ende 12 der Sicke 8 in Höhe des Wulstes 6. Deshalb ist der Wulst an dieser Stelle bei 13 :bis ,auf die Höhe des planen Teiles eingedrückt. In diese Lücke des Wulstes 6 legt sich als Abschluß des Führungskanals das Ende 12 der Sicke B. Diese Lage wiederholt sich spiegelbildlich an den Stellen 14 b'zw. 15. Durch das Ineinand'ergreifen der Sicken ist es ermöglicht, ohne jede Schweißarbeit die Stromkanäle gegeneinander abzugrenzen, so daß alle mit der Notwendigkeit des Schweißens zusammenhängenden Schw ierigIkeite:n, wie teure Herstellung, unsauberes Aussehen der Platten, Rostbildung usw., vollkommen beseitigt sind.In. the drawing i is the plane part of the plate, which is surrounded all around by a groove 2 for receiving a rubber seal. This sealing groove also encloses the inflow holes, e.g. B. at 3. At points where the flow of liquid must be closed against the interior of the plate, N-connecting pieces made of rubber are inserted, which are also in grooves (beads), z. B. at 4. These grooves can, of course, only be formed in the sheet metal in that the sheet metal is pressed up on both flanks of the grooves 2. The beads 5 and 6 then arise, between which the recessed groove 2 then lies. The channels 7-7 are delimited by the beads 8, 9, io and ii, which force the liquids to flow in zigzag over the plates. These beads are raised upwards (towards the beholder). If the plate package is put together operationally, that is, you put z. B. d'ie plate drawn on the left over the one drawn on the right, the end 12 of the bead 8 is at the level of the bead 6. Therefore, the bead is at this point at 13 : bis, pressed in at the level of the flat part. The end 12 of the bead B lies in this gap in the bead 6 as the end of the guide channel. This position is repeated in mirror image at the points 14 and / or. 15. The interlocking of the beads makes it possible to delimit the current channels from one another without any welding work, so that all difficulties associated with the necessity of welding, such as expensive production, unclean appearance of the plates, rust formation, etc., are completely eliminated are.
