Description

  

  Kühlflüssigkeit     führende        Hochfrequenzenergieleitung       Für die Verbindung eines HF-Generators mit  einem Induktor oder dergleichen werden mit Vorteil  koaxiale Leitungen verwendet. Die Zu- und Abfüh  rung von Kühlwasser an solche Verbraucher     erfolgt     dabei mittels zusätzlicher Schlauchleitungen. Für viele  Zwecke ist die Verlegung besonderer Schlauchleitun  gen für das Kühlwasser unerwünscht.  



  Aufgabe der Erfindung ist es daher, die Hoch  frequenzenergieleitung selber für die Kühlwasserlei  tung     mitzuverwenden.     



  Die Erfindung betrifft eine Kühlflüssigkeit füh  rende     Hochfrequenzenergieleitung,    die sich dadurch  auszeichnet, dass der Innenleiter ein Rohr ist und  dieses von einem anliegenden wasserundurchlässigen  Isoliermantel umschlossen ist und dass zwischen der  Innenwand des     rohrförmigen    Aussenleiters und dem  Isoliermantel ein Zwischenraum besteht und dass die  ser Zwischenraum sowie der rohrförmige Innenleiter  zur Führung des Kühlmittels, z. B. für den Induktor,  dienen.  



  Die Erfindung wird anhand eines Ausführungsbei  spieles näher erläutert.  



  Die Zeichnung zeigt den Aufbau der     Hochfre-          quenzleitung.    1 ist der     rohrförmige    Innenleiter. Um  den Innenleiter ist ein satt anliegender wasserundurch  lässiger Isoliermantel 2 umgelegt. Dieser     Isolierman-          tel    kann aus Kunststoff, z. B. Polyäthylen,     Teflon     usw., oder aus Gummi bestehen. Im Innenraum 1a  des Innenrohres fliesst das Kühlmittel, z. B. Wasser,  in der einen Richtung. Um das Ganze erstreckt sich  mit einem Zwischenraum 3 der     rohrförmige    Aussen  leiter 4. Der Zwischenraum ist so gewählt, dass er  die notwendige     Kühlmittelmenge,    z. B.

   Wasser, so  zu führen vermag, dass der Druckabfall tragbar, etwa  wie derjenige des Innenrohres ist. Hierfür ist ein  relativ kleiner Zwischenraum erforderlich.    Die     Befürchtung,    dass, wenn als Kühlmittel Was  ser verwendet wird, der     Hochfrequenzstrom    zum Teil  in dem Wasser fliesst und deshalb hohe Verluste zu  erwarten wären, trifft nicht zu. Messungen ergaben,  dass bei einer solchen Leitung eine Güte der  Leitung von über 100 erreicht wird, bei
EMI0001.0017  
   einer     Induk-          tivität    der Leitung von etwa 0,1     ,u        Hy/m.     



  Wenn die Leitung in Verbindung mit einem In  duktor verwendet wird, ergeben sich relative Verluste  von nur wenigen Prozenten.  



  Das Kühlmittel, welches über die Hochfrequenz  energieleitung hin und zurück fliesst, lässt sich in be  sonders einfacher Weise durch den Induktor hin  durchleiten. Das die     I'Iochfrequenzspannung        führende     Innenrohr ist durch das geerdete Aussenrohr voll  ständig abgeschirmt. Die Innenleitung braucht auch  nicht genau koaxial zu liegen. Der     Innenleiter    mit  dem Isoliermantel darf einseitig an der Innenwand  des Aussenrohres anliegen, ohne dass sich daraus nach  teilige elektrische Verhältnisse ergeben würden. Die       Kupferrohrleiter    erlauben infolge ihrer zylindrischen  Enden das Anbringen von flüssigkeitsdichten An  schlüssen in besonders zuverlässiger Weise.



  Radiofrequency power line carrying coolant For the connection of an HF generator to an inductor or the like, coaxial lines are advantageously used. The supply and discharge of cooling water to such consumers takes place by means of additional hose lines. For many purposes, the laying of special hose lines for the cooling water is undesirable.



  The object of the invention is therefore to use the high-frequency power line itself for the Kühlwasserlei device.



  The invention relates to a cooling liquid leading high-frequency power line, which is characterized in that the inner conductor is a tube and this is enclosed by an adjacent water-impermeable insulating jacket and that between the inner wall of the tubular outer conductor and the insulating jacket there is a space and that this space and the tubular inner conductor for guiding the coolant, e.g. B. for the inductor, serve.



  The invention is explained in more detail using a game Ausführungsbei.



  The drawing shows the structure of the high-frequency line. 1 is the tubular inner conductor. A tightly fitting water-impermeable insulating jacket 2 is wrapped around the inner conductor. This insulating jacket can be made of plastic, e.g. B. polyethylene, Teflon, etc., or made of rubber. In the interior 1a of the inner tube, the coolant flows, for. B. water, in one direction. To the whole extends with a space 3 of the tubular outer conductor 4. The space is chosen so that it has the necessary amount of coolant, for. B.

   Water, able to lead in such a way that the pressure drop is tolerable, roughly like that of the inner pipe. A relatively small gap is required for this. The fear that, if water is used as the coolant, the high-frequency current flows partly in the water and therefore high losses would be expected, does not apply. Measurements showed that such a line achieves a line quality of over 100, at
EMI0001.0017
   an inductance of the line of about 0.1 u Hy / m.



  If the line is used in conjunction with an inductor, the relative losses are only a few percent.



  The coolant, which flows back and forth over the high-frequency power line, can be passed through the inductor in a particularly simple manner. The inner tube carrying the high frequency voltage is fully shielded by the earthed outer tube. The inner line does not have to be exactly coaxial either. The inner conductor with the insulating jacket may rest on one side of the inner wall of the outer tube without this resulting in disadvantageous electrical conditions. Due to their cylindrical ends, the copper pipes allow the attachment of liquid-tight connections in a particularly reliable manner.
