Description
Wassergekühlte hochspannungs- und strahlensichere Röntgenröhre mit an Hochspannung liegender Anode Trockengekühlte Röntgenröhren mit Strahlenschutz und gleichzeitigem Hochspannungsschutz sind bekannt. Der Hochspannungsschutz wird allgemein dadurch erreicht, daß entweder die ganze Röhre in einer durchschlagsicheren. Isolierhülle eingebaut ist,- wobei letztere noch mit einer geerdeten Metallhülle umgeben werden kann, oder aber daß die Röhre von einer geerdeten Metallhülle in so großer Entfernung umgeben ist, daß von den hochspannungführenden Teilen der Röhre durch die zwischenbefindliche Luft auf die geerdete Schutzhülle kein Funkenübergang stattfinden kann. Um die. Funkenschlagweite zu vergrößern und die Entfernung des spannungführenden Rippenkühlers von der geerdeten Metallhaube zu verkleinern, sind auch schon versetzte Lamellen aus Isolierstoff in den Zwischenraum eingebaut Urorden. Um die notwendige Kühlung des Rippenkühlers oder auch andersgeformten Kühlers zu :erreichen, sind eine Anzahl. Öffnungen vorgesehen, welche die Lüftung ermöglichen. Auch wurde des :öfteren ein eingebauter Ventilator oder zugeführte Preßluft mit Erfolg angewandt.Water-cooled high-voltage and radiation-safe X-ray tube with Anode connected to high voltage. Dry-cooled X-ray tubes with radiation protection and simultaneous high voltage protection are known. The high voltage protection will generally achieved by either the whole tube in a puncture-proof. Insulating cover is installed - the latter still having a grounded metal cover can be surrounded, or that the tube can be surrounded by a grounded metal sheath so far away that it is surrounded by the high-voltage parts of the tube No spark transfer due to the air in between on the earthed protective cover can take place. To the. To increase the spark width and the distance of the live finned cooler to be reduced from the grounded metal hood Also staggered lamellas made of insulating material built into the space between the primeval order. To provide the necessary cooling for the finned cooler or other shaped cooler : reach are a number. Openings provided to allow ventilation. Also, a built-in fan or compressed air was often used Success applied.
Erfindungsgemäß wird eine gute Kühlung ohne Preßl.uft und Ventilatoren und ohne große Hochspannungsschutzhaube bei kleinstmöglichen Dimensionen dadurch erreicht, daß die abzuführende Wärme der Anode über einen mit ihr öder ihrem Kühler wärmegekuppelten großflächig anliegenden festen Isolator, z. B. Porzellan, und über eine an dem Isolator großflächig anliegende geerdet von dem Kühlwasser umspülte Metallhülse abgeleitet wird.According to the invention, good cooling is achieved without compressed air and fans and without a large high-voltage protective hood with the smallest possible dimensions achieves that the heat to be dissipated from the anode via a with it or its cooler heat-coupled, large-area adjacent solid insulator, e.g. B. Porcelain, and about one that rests on the insulator over a large area and is earthed by the cooling water Metal sleeve is derived.
Hierdurch wird -: es ermöglicht, eine auf Hochspannung liegende Anode auf einfache Weise durch Anschluß an die Wasserleitung zu kühlen.This makes it possible to have a high-voltage anode easy to cool by connecting to the water pipe.
In der schematischen Darstellung der Röhre Abb. i und 2 stellt i den unmittelbar mit der Anode in Verbindung stehenden Teil der Kühlvorrichtung dar. In Ahb. i ist der Querschnitt eines solchen aus Metallen oder Metallegierungen hergestellten Teils von der Form :eines H und in Abb. 2 von der Form eines U. 2 ist der wärmeleitende, jedoch durchschlagsichere Isolator; welcher die Röhre ganz umgibt und welcher beispielsweise in der Mitte unterteilt sein kann: Das im Querschnitt H- oder U-förmige metallische Kühlelement i muß mit der Isolierhülle 2 besten Wärmekontakt von solcher Größe hesitzen, daß die geringere Leitfähigkeit des Isolators keine Rolle mehr spielt. Besonders gut zu erreichen ist dies durch Ausfüllen des Zwischenraumes mit einem leicht deformierbaren guten Wärmeleiter, z. B. Quecksilber und seine Amalgame, Woodsches Metall usw. Der durchschlagsichere Isolator, z. B. aus Porzellan, ist auf seiner Außenseite mit einer eng anliegenden Metallhülle 3 umgeben, deren Wandstärke groß genug ist, um eine Weiterleitung der Wärme auf die ganze oder einen Großteil der Oberfläche zu .ermöglichen und gleichzeitig ,einen Teil der Röntgenstrahlenabsorptiön zu übernehmen. Ein guter Wärmekontakt auf der Außenseite des Isolators kann durch galvanischen Metallüberzug oder durch Bespritzen mit Metallen, Verfahren nach Schoop, usw. hergestellt werden.In the schematic representation of the tube Fig. I and 2 i represents the part of the cooling device that is directly connected to the anode. In Ahb. i is the cross-section of such a part made of metals or metal alloys of the shape: of an H and in Fig. 2 of the shape of a U. 2 is the thermally conductive, but puncture-proof insulator; which completely surrounds the tube and which can, for example, be divided in the middle: the metal cooling element i, which is H- or U-shaped in cross-section, must have the best thermal contact with the insulating sleeve 2 and of such a size that the lower conductivity of the insulator no longer plays a role. This is particularly easy to achieve by filling the gap with an easily deformable good heat conductor, e.g. B. Mercury and its amalgams, Wood's metal, etc. The puncture-proof insulator, z. B. made of porcelain, is surrounded on its outside with a tight-fitting metal shell 3, the wall thickness is large enough to allow the heat to be passed on to all or a large part of the surface and at the same time to take over part of the X-ray absorption. Good thermal contact on the outside of the insulator can be achieved by galvanic metal coating or by spraying with metals, using the Schoop method, etc.
