Kahlverfahren für Röntgenröhren.
Es ist bekannt, durch kontinuierliche Erneuerung des Kühlwassers oder durch Einlassen von Luft die Antikathode der Röntgenröhre zu kühlen.

wieder Entladungen ergeben.
Das nachstehend angegebene erfndungsgemässe Kühlverfahren, welches darin besteht, dass nicht die Antikathode direkt, sondern das nissige Kühlmittel gekühlt wird, behebt nun die angeführten Übelstände, weil es gestattet, das flüssige Kühlmittel auf einer bestimmten Temperatur zu erhalten und dielSiedehitze und rasche Verflüchtigung des flüssigen Kühlmittels zu verhindern.
Ferner sind statische Aufladungen ausgeschlossen und ist das Verfahren ohne bedeutende Vorkehrungen und ohne den Röhren mit KühICüasigkeit erst eine bestimmte Form geben zu müssen überall leicht in Anwendung zu bringen.
Das Verfahren soll an Hand der in der Figur dargestellten Röntgenröhre erläutert werden.
Es besteht darin, dass in die Kühlabteilung K der Röntgenröhre R ein Ausströmer AS, welcher bis an die Antikathode A reicht, eingelegt wird. Dieser Ausströmer ist ein mit einem für Gase leicht durchgängigen Pfropfen PF an dem der Antikathode zugewendeten Ende verschlossenes Rohr. Durch das Rohr wird ein Gas, z. B. Luft, in das flüssige Kühlmittel, z. B. Wasser. durch die Poren des Pfropfen PF hindurchgepresst. Das Gas durchströmt in Form von. Gasperlen das flüssige Kühlmittel, nimmt, die in demselben angesammelte Wärme leicht auf und entweicht, an der Oberfläche des flüssigen Kühlmittels angelangt, in den Raum.
Insbesondere bei der Therapie, wo das Auswechseln der Röhren oder das fortwährende Erneuern des verdampften flüssigen Kühlmittels eine sehr störende Unterbrechung verursacht, ist die angegebene Methode von nicht zu unterschätzendem Vorteile.

Kahlverfahren for X-ray tubes.
It is known to cool the anticathode of the X-ray tube by continuously renewing the cooling water or by letting in air.
EMI1.1
again results in discharges.
The cooling method according to the invention given below, which consists in not cooling the anticathode directly, but the sneaky coolant, now remedies the disadvantages mentioned, because it allows the liquid coolant to be kept at a certain temperature and the boiling point and rapid volatilization of the liquid coolant to prevent.
Furthermore, static charges are excluded and the process can easily be used everywhere without significant precautions and without first having to give the tubes with coolness a certain shape.
The method will be explained using the X-ray tube shown in the figure.
It consists in that in the cooling compartment K of the X-ray tube R, an outflow AS, which extends as far as the anticathode A, is inserted. This outflow is a tube closed with a plug PF, which is easily through-going for gases, at the end facing the anticathode. A gas, e.g. B. air, into the liquid coolant, e.g. B. water. pressed through the pores of the plug PF. The gas flows through in the form of. Gas pearls, the liquid coolant, easily absorbs the heat that has accumulated in it and escapes into the room when it reaches the surface of the liquid coolant.
Particularly in therapy, where the replacement of the tubes or the continuous renewal of the vaporized liquid coolant causes a very disturbing interruption, the indicated method has advantages that should not be underestimated.
