Description

Die Erfindung bezieht sich auf eine Hochfrequenzröhre zur Erzeugung oder Verstärkung sehr kurzer Wellen, bei der die Innentemperatur ihres Gefäßes während des Betriebes mindestens annähernd konstant gehalten wird.The invention relates to a high frequency tube for generating or amplifying very short waves at which the internal temperature of your vessel is kept at least approximately constant during operation.

Es s'ind bereits Röhren dieser Art bekannt, bei denen die Innentemperatur durch um die Gefäßwand herumgelegte Kühlschlangen auf einen annähernd gleichbleibenden Wert herabgesetzt wird. Andere bekannte Vorrichtungen verwenden zur Kühlung der Gefäßwand motorisch angetriebene Gebläse, deren Luftmenge in Abhängigkeit von der Temperatur der Gefäßwand geregelt wird.Tubes of this type are already known in which the internal temperature passes around the vessel wall cooling coils lying around is reduced to an approximately constant value. Other known Devices use motor-driven fans to cool the vessel wall, their Air volume is regulated depending on the temperature of the vessel wall.

Im Gegensatz zu den bekannten Vorrichtungen wird gemäß der Erfindung vorgeschlagen, die Temperaturkompensation durch eine zusätzliche Heizvorrichtung zu erzielen, die in die Wandung des Gefäßes eingebaut ist. Der besondere Vorteil einer solchen Anordnung besteht darin, daß insbesondere beim Einschalten der Röhre rasch die erforderlichen Temperaturwerte erreicht werden und sich schon nach kurzer Zeit ein stabilisierter Zustand 'einstellt. Dies ist besonders bei tragbaren Therapiegeräten von Vorteil, die schnell einsatzbereit sein sollen. Außerdem kann die Heizvorrichtung wegen des Einbaues in die Gefäßwand und der sich daraus ergebenden guten Wärmeleitung für verhältnismäßig kleine Leistungen bemessen werden und bedarf daher keiner zusätzlichen Armaturen od. dgl., wie dies bei den seither bekannten Vorrichtungen der Fall war.In contrast to the known devices, the invention proposes temperature compensation to be achieved by an additional heating device built into the wall of the vessel is. The particular advantage of such an arrangement is that, especially when switching on the required temperature values can be reached quickly and after a short time a stabilized state 'sets. This is particularly advantageous with portable therapy devices that work quickly should be ready for use. In addition, because of the installation in the vessel wall and the resulting good heat conduction can be measured for relatively small capacities and therefore does not require any additional fittings or the like, as is the case with the devices known since then was the case.

In der Zeichnung ist als Ausführungsbeispiel der Erfindung eine Magnetfeldröhre teilweise in der Ansicht und teilweise im Schnitt dargestellt.In the drawing, as an exemplary embodiment of the invention, a magnetron tube is partially in view and shown partially in section.

Der mit 1 bezeichnete Anodenkörper der Magnetfeldröhre hat an seinen beiden Stirnseiten je einen Deckel 2. In seinem Innern ist das Schwingsystem 3 und ehne in der Zeichnung nicht näher erkennbare Kathode enthalten, deren Zuführungsleitungen mit 4 bezeichnet sind. Zur Auskopplung der im Schwingsystem erregten Leistung dient ein stabförmiger Dipol 5. The anode body, denoted by 1, of the magnetron tube has a cover 2 on each of its two end faces. Inside, the oscillating system 3 and a cathode, which cannot be seen in detail in the drawing, are contained, the supply lines of which are denoted by 4. A rod-shaped dipole 5 is used to decouple the power excited in the oscillating system.

An den Anodenkörper 1 ist ein Block 6 angegossen oder angebaut, der eine zusätzliche Heizwicklung 7 und einen Thermoschalter 8 enthält. Mit den Kontakten 9 wird diese Heizwicklung an die Stromversorgung des Hochfrequenzgenerators angeschlossen. Sobald der Generator eingeschaltet wird und solange der Bimetallstreifen 8 noch kalt ist, ist die Zusatzheizung 7 eingeschaltet, so daß das Röhrengefäß 1, 2 schnell aufgeheizt wird. Sobald bei hoher Belastung die Innentemperatur des Röhrengefäßes infolge der Röhrenverlustleistung steigt und die durch die thermischen Veränderungen der mechanischen Bauelemente bedingte Frequenzabweichung die zulässigen Werte Temperaturstabilisierte HochfrequenzröhreA block 6, which contains an additional heating winding 7 and a thermal switch 8, is cast or built onto the anode body 1. With the contacts 9 this heating winding is connected to the power supply of the high-frequency generator. As soon as the generator is switched on and as long as the bimetallic strip 8 is still cold, the auxiliary heating 7 is switched on so that the tubular vessel 1, 2 is heated up quickly. As soon as the internal temperature of the tubular vessel rises due to the tube power loss and the frequency deviation caused by the thermal changes in the mechanical components increases the permissible values, temperature-stabilized high-frequency tube
