Description
Die Gummidichtungen für die Rand- und Kanalabdichtungen bei Wärmeaustauschplatten sind entweder in besondere Nuten '^eingelegt oder auf das ebene Blech aufvulkanisiert. Um ein besseres Halten des aufvulkanisierten Gummistreifens zu erzielen, sind Löcher in das Blech gebohrt, Stifte eingenietet oder Drähte eingelegt.The rubber seals for the edge and duct seals on heat exchange plates are either inserted into special grooves' ^ or vulcanized onto the flat sheet. To better hold the vulcanized To achieve rubber strips, holes are drilled in the sheet metal, pins are riveted in or wires inserted.
Das Einbohren von Löchern 'und Einnieten von Stiften schwächt aber das Blech, und" das einvulkanisierte Gummi wird beim Pressen ziemlich stark eingeschnitten 'und löst sich nach verhältnismäßig kurzer Zeit. Auch eingelegte Drähte können, erfahrungsgemäß das Lösen der Gummistreifen nicht verhindern.But drilling holes and riveting pins weakens the sheet metal, and " the vulcanized rubber is cut quite severely during pressing and comes off after a relatively short time. Experience has shown that even inserted wires can do that Do not prevent the rubber strips from loosening.
Man hat auch vorgeschlagen, Löcher oder Schlitze in das Blech zu bohren und deren Ränder gegebenenfalls wechselseitig umzubiegen. Dadurch wird aber das Blech geschwächt, und die Gummidichtung kann bei dem erforderlichen starken Preßdruck beschädigt werden.It has also been proposed to drill holes or slots in the sheet metal and their If necessary, bend the edges alternately. But this weakens the sheet metal, and the rubber seal can be damaged by the required strong pressing pressure.
In völlig anderer Weise wird nun die Aufgabe, Gummistreifen in sicherer Weise aufIn a completely different way, the task of applying rubber strips in a safe manner is now
as den Platten zu befestigen, durch die vorliegende Erfindung gelöst, indem die Platte in der Auflagefläche für den Gummi quer zur Richtung der Gummileiste geschlitzt, die so entstandenen Abschnitte brückenartig wechseiweise nach oben und unten durchgebogen und von dem Gummi eingeschlossen sind. Auf diese Weise entsteht ein durch die Brükken geschlungener Gummistreifen ο ohne jede Unterbrechung, der durch die verhältnismäßig breiten Zargen sicher festgehalten wird. As to fasten the plates, solved by the present invention, in that the plate in the support surface for the rubber is slit transversely to the direction of the rubber strip, the resulting sections are bent up and down like a bridge and are enclosed by the rubber. This creates a rubber strip looped through the bridges ο without any interruption, which is securely held in place by the relatively wide frames.
Die Erfindung wird durch die beiliegende Zeichnung veranschaulicht, und zwar zeigt
Abb, ι eine Draufsicht,
Abb. 2 einen Schnitt A-Ä der Abb. i,
Abb. 3 einen Schnitt B-B der Abb. i. '40The invention is illustrated by the accompanying drawing, namely shows
Fig, ι a top view,
Fig. 2 a section A-Ä of Fig. I,
Fig. 3 shows a section BB of Fig. I. '40
In den Abbildungen sind α die Platten, b die Einschnitte. Die dadurch entstandenen Abschnitte c werden abwechselnd nach oben und abwärts gebogen, so daß sie, wie in Abb. 2 gezeigt, Brücken d bilden. Durch dieses Gebilde hindurch wird die Gummischicht e aufvulkanisiert und ist so außerordentlich haltbar.In the figures, α are the plates, b the incisions. The resulting sections c are alternately bent up and down so that, as shown in Fig. 2, they form bridges d. The rubber layer e is vulcanized through this structure and is therefore extremely durable.
