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.
