Description
Wärmeaustausohplatten für Flüssigkeiten bestehen vielfach aus: massivem Material, indas die Ströniungskaniäle für die.Flüssigkeiten eingefräst sind. Derartige Plätten sind niciht nur stehwer, sondern auch in der Herstellung teuer. Man hat daher auch, sogenannte Gitterplatten vorgeschlagen, die aus iejtnem Rahmen bestehen., und bei denen die StromungB-kanäle durch Stege gebildet werden. Um die einzelnen Kanäle miteinander zu verbänden, sind die Stege äb'wedhselhd, recjhts tundj. links unterbrochen, so daß der sitih über die ganze Platte erstreckende .zickzacHörmige Strömungskanal entsteht.- -■' · ■"■'■ - -; -; Derartige Gitterplatten sind. ;_nicht jam leicht, sondern auch billig herzustellen. Sie iiaben aber den schwer wiegenden Nachteil, daß sie gegen inneren Druck wenig wider-., standsfiähig sind. Sind nämlich eine Anzahl solcher Gitterplatten mit ■ den zugehörigen Zwischenplatteii zu einem vollständigen Wärmeaustauschapparat zusammengesetzt, so .entsteht beim Hdndurchdrüicken der Flüissig- : keiten infolge der Reibungswiderstände 'ein mehr oder weniger hoher Druck, Der Rahmen biegt sich dann durch, und die Dichtungen werden dadurch beschädigt.Heat exchange plates for liquids often consist of: Solid material into which the flow channels for the liquids are milled. Such plates are not just cheap, but also expensive to manufacture. So-called grid plates have therefore also been proposed, which consist of a single frame and in which the flow channels are formed by webs. To connect the individual channels with one another, the webs are äb'wedhselhd, recjhts tundj. interrupted the left so that the sitih over the plate extending .zickzacHörmige flow channel entsteht.- - ■ '* ■ "■' ■ - -; -; Such grids are; _not_ jam light, but also inexpensive to produce but you iiaben the.. The serious disadvantage is that they are not very resistant to internal pressure, because if a number of such grid plates with the associated intermediate plates are put together to form a complete heat exchange apparatus, then when the liquids are pushed through by the hand, one more is created due to the frictional resistance or less high pressure, the frame will then bend and the seals will be damaged.
Diese Nachteile der Gitterplatten sollen durch die Erfindung beseitigt werden. Die Erfindung· kennzeichnet sich dadurch, daß die die 'Strömungsiranale begrenzenden. Stege sich über die ganze Platte erstrecken und beiderseitig· an dem Rahmen auf eine an sich bekannte Weise befestigt sind, z. B. durch Nieten. Löten,* Schweißen oder durch Anschrauben. These disadvantages of the grid plates are intended to be eliminated by the invention. the Invention · is characterized in that the the 'flow iranals limiting. Bars extend over the entire plate and on both sides on the frame on a per se known Way are attached, e.g. B. by riveting. Soldering, * welding or screwing.
Um aber nun auch die . Möglichkeit zu geben, den zidkzaokföirmigen Strömungskanal zu bilden, sind die einzelnen Stäbe ab wechselnd rechts und links gedreht, also auf ein erforderliches Stück nicht mehr hochkant, sondern flach gelegt.But now also the. Possibility to give to form the zidkzaokföirmigen flow channel, the individual rods are off rotated alternately right and left, i.e. no longer upright on a required piece, but laid flat.
In der -beiliegenden Zeichnung wird die verbesserte Gitterplatte gemäß der Erfindung dargestellt. Es ist α >ein Rahmen aus Formmaterial mit Nuten" zum Einlegen der Dichtungsschnur, b, b sind Tragbleche zum Aufhängen der Platte auf geeignete .Träger, Die Stege C sind Blechstreifen oder schwache Flachstäbe, die bei d um 900 gedreht oder flach gearbeitet sind, um auf diese Weise die . . Strömungskanöle herzustellen. Die Tragbleche & ■wie die-StegeC sind in geeigneter Weise'mit dem Rahmen α verbunden.' Im zusammengebauten Zustande Begt an den Stirnselten der dargestellten Gitterplatte je eine ebene Platte, so daß auf diese Weise durch die Gitterplatte die zidkzaCkförmigen Kanäle für die Flüssigkeiten gebildet werden. Da die Stege & rechts und links mit dem Rah-. TBSB.it fest verbunden sind, entsteht im Sinne' der, Erfindung eine Gitterplatte, die gegen inneren Druck sehr widerstandsfähig und dabei leicht und bilBg hergestellt werden kann.In the accompanying drawing, the improved grid plate according to the invention is shown. It is α > a frame made of molded material with grooves "for inserting the sealing cord, b, b are support plates for hanging the plate on suitable .Träger, The webs C are sheet metal strips or weak flat bars that are rotated by 90 0 at d or worked flat In order to produce the... flow channels in this way. The support plates & ■ like the webs C are connected in a suitable manner to the frame α . In the assembled state, a flat plate is placed on each of the front faces of the grid plate shown, so that the zidkzaCk-shaped channels for the liquids are formed through the grid plate, since the webs right and left are firmly connected to the frame. TBSB.it In the sense of the invention, a grid plate is created which is very resistant to internal pressure and can be produced easily and inexpensively.
