Description

Kühlflügel für Elektroden von Entladungsröhren Bei elektrischen Entladungsgefäßen, insbesondere bei Senderöhren hoher Leistung, kann im; Betrieb eine so starke Erwärmung des Gitters und der Anode auftreten, daß es notwendig ist, die Wärme von den Elektroden abzuführen, um: ein -Schadhaftwerden derselben zu vermeiden. Zur Abführung der Wärme werden deshalb die Elektroden vielfach mit wärmeabstrahlenden Kühlflügeln versehen oder gar mit einer Kühlflüssigkeit gekühlt. Es besteht nun die Gefahr, da.ß derartige Kühlflügel, insbesondere wenn sie an mechanisch nicht besonders festen Elektroden, beispielsweise an Gittern, angebracht sind, infolge der verschieden hohen Temperatur in: radialer Richtung ihre Form ändern und dadurch auch eine Verwerfung der Elektroden herbeiführen, die das ganze Entladungsgefäß unbrauchbar machen kann.Cooling blades for electrodes of discharge tubes For electrical discharge vessels, especially in the case of high-power transmission tubes, in the; Operation such a strong warming of the grid and the anode occur that it is necessary to remove the heat from the electrodes to: avoid damage to the same. To dissipate the heat Therefore, the electrodes are often provided with heat-radiating cooling blades or even cooled with a coolant. There is now the danger that such Cooling blades, especially if they are attached to electrodes that are not particularly strong mechanically, for example on grids, due to the different high temperatures in: the radial direction change their shape and thereby also a warping of the electrodes cause that can make the entire discharge vessel unusable.

Es sind bereits Elektronenröhren bekannt, bei denen die Elektroden mit den zugehörigen Kühlrippen aus einem Stück bestehen. Die Elektroden werden von mehreren Stangen, die an jeder Kühlrippe befestigt sind, nach: Art eines Auslegers getragen. Bei diesen bekannten Anordnungen gelingt nur schwer eine Zentrierung der Elektroden. Zudem, können bei den bekannten Anordnungen durch thermische Ausdehnung der Kühlrippen Änderungen des Abstandes der Elektroden erfolgen.There are already known electron tubes in which the electrodes consist of one piece with the associated cooling fins. The electrodes are from several rods attached to each cooling fin, according to: type of cantilever carried. With these known arrangements, it is difficult to center the Electrodes. In addition, in the known arrangements, thermal expansion the cooling fins changes in the distance between the electrodes.

Diese Nachteile werden bei Kühlflügeln für Elektroden von Entladungsröhren dadurch vermieden, d.aß erfindungsgemäß der Flügel. aus einem Blech besteht, das mit seiner einen Kante .an der Elektrode befestigt und in Richtung zu der der befestigten Kante abgewandten Kante hin mit Wellen versehen ist, deren Höhe zu der freien Kante hin zunimmt. Diese Anordnung zeichnet sich einerseits durch eine besonders große Oberfläche und andererseits durch hohe mechanische Steifigkeit .aus. Mechanische Spannungen, die als Folge verschiedener Temperaturen auftreten, werden sich ausgleichen und nicht auf die Elektrode übertragen, da Elektrode und Kühlflügel aus getrennten Teilen bestehen. Zudem besitzen die Kühlflügel .eine gute Wärmeableitung, da der Wärmewiderstand von der Elektrode zu den Enden der Kühlflügel abnimmt.These disadvantages become apparent in the case of cooling blades for electrodes of discharge tubes thereby avoided, d.aß according to the invention of the wing. consists of a sheet metal that with its one edge. attached to the electrode and in the direction of that of the attached Edge facing away from the edge is provided with waves, the height of which corresponds to the free edge increases towards. This arrangement is characterized on the one hand by a particularly large Surface and, on the other hand, high mechanical rigidity. Mechanical Tensions that occur as a result of different temperatures will even out and not transferred to the electrode, as the electrode and cooling wing are separate Share exist. In addition, the cooling blades have good heat dissipation because the Thermal resistance from the electrode to the ends of the cooling blades decreases.

In der beiliegenden Zeichnung ist ein Ausführungsbeispiel der Erfindung in Ansicht (Abb. i) und Aufsicht (Abb. a ) dargestellt. An den Gitterstreben i eines in bekannter Weise hergestellten Gitters sind die im Querschnitt sektorförmig ausgebildeten Kühlflügel :3, etwa durch Sch-%veißen, befestigt.In the accompanying drawing is an embodiment of the invention shown in elevation (Fig. i) and top view (Fig. a). On the lattice struts i one Grids produced in a known manner are those with a sector-shaped cross-section Cooling blades: 3, fastened, for example, by welding%.
