この考案は空冷式クライストロン装置に係り、特にそのチュ−ナの駆動部を冷 却する手段に関する。 The present invention relates to an air-cooled klystron device, and more particularly to a means for cooling the drive part of its tuner.
【０００２】[0002]
従来、空冷式クライストロン装置の周波数調整機構（以下，チュ−ナと略称） 付近は、図３に示すように構成され、図中の符号１は高周波作用部の出力空胴、 ２は出力空胴１に設けられたチュ−ナであり、このチュ−ナ２の駆動部はチュ− ナロッド３，ねじ４，ベロ−ズ５などからなっている。６は出力導波管、７はポ −ルピ−ス、８は空冷式コレクタ、９は複数の放熱フィンである。そして、動作 時にはコレクタ外囲器１０の吸気孔１１から冷却風１２が導入され、この冷却風 １２は複数の放熱フィン９の間を通過してコレクタ８を冷却する。 Conventionally, the vicinity of a frequency adjusting mechanism (hereinafter, abbreviated as a tuner) of an air-cooled klystron device is configured as shown in FIG. The tuner 2 is provided with a tuner rod 3, and a driving portion of the tuner 2 includes a tuner rod 3, a screw 4, a bellows 5, and the like. Reference numeral 6 is an output waveguide, 7 is a pole piece, 8 is an air-cooled collector, and 9 is a plurality of radiation fins. Then, during operation, cooling air 12 is introduced from the intake holes 11 of the collector envelope 10, and the cooling air 12 passes between the plurality of radiating fins 9 to cool the collector 8.
【０００３】[0003]
一般にクライストロンにおける高周波作用部の共振空胴は、高周波出力の効率 や帯域，利得を得るために、上記のようにチュ−ナ２を持っている。特に、出力 空胴１においては、チュ−ナ２で発生する高周波損失は、他の共振空胴より非常 に大きくなる。即ち、高周波損失は共振空胴が励起されるパワ−の約０．４％程 度も、損失すると考えられる。このようなチュ−ナ２で発生する高周波損失は、 チュ−ナ２に大きな温度上昇をもたらすため、管内ガスの増加やチュ−ナ２の駆 動部の機械的な不具合（例えばチュ−ナロッド３の焼き付き）を生じさせる。 Generally, the resonance cavity of the high frequency acting part in the klystron has the tuner 2 as described above in order to obtain the efficiency, band and gain of the high frequency output. In particular, in the output cavity 1, the high frequency loss generated in the tuner 2 is much larger than that of other resonant cavities. That is, it is considered that the high frequency loss is about 0.4% of the power in which the resonant cavity is excited. The high-frequency loss generated in the tuner 2 causes a large temperature rise in the tuner 2 and thus increases the gas in the pipe and mechanical failure of the driving part of the tuner 2 (for example, the tuner rod 3). Image sticking).
【０００４】 この考案は、高周波損失による温度上昇が抑制され、大電力動作でもチュ−ナ の駆動部の焼き付き等を防止出来る空冷式クライストロン装置を提供することを 目的とする。An object of the present invention is to provide an air-cooled klystron device in which temperature rise due to high-frequency loss is suppressed and seizure of the drive part of the tuner can be prevented even at high power operation.
【０００５】[0005]
【課題を解決するための手段】 この考案は、チュ−ナが取付けられた出力空胴にポ−ルピ−スを介して空冷式 コレクタが連結され、更にポ−ルピ−スに通気孔が形成され、この通気孔を通し てコレクタを冷却する冷却風の一部がチュ−ナの駆動部に案内されるように構成 されてなる空冷式クライストロン装置である。According to the present invention, an air-cooled collector is connected through a pole piece to an output cavity having a tuner, and a vent hole is formed in the pole piece. The air-cooled klystron device is configured such that a part of the cooling air that cools the collector through the vent holes is guided to the drive portion of the tuner.
【０００６】[0006]
この考案によれば、高周波損失による温度上昇が抑制され、大電力動作でもチ ュ−ナの駆動部の焼き付き等を防止出来る。 According to this invention, temperature rise due to high frequency loss is suppressed, and burn-in of the drive section of the tuner can be prevented even at high power operation.
【０００７】[0007]
以下、図面を参照して、この考案の一実施例を詳細に説明する。 この考案による空冷式クライストロン装置の要部は図１に示すように構成され 、従来例（図３）と同一箇所は同一符号を付すことにする。 An embodiment of the present invention will be described in detail below with reference to the drawings. The main part of the air-cooled klystron device according to the present invention is constructed as shown in FIG. 1, and the same parts as those in the conventional example (FIG. 3) are designated by the same reference numerals.
【０００８】 即ち、図中の符号１は高周波作用部の出力空胴であり、この出力空胴１には出 力導波管６が連結されると共に、チュ−ナ２が設けられている。このチュ−ナ２ の駆動部は、チュ−ナ板２ａ，チュ−ナロッド３，ねじ４，ベロ−ズ５などから なっている。更に、出力空胴１には軸方向にポ−ルピ−ス７を介して空冷式コレ クタ８が連結され、このコレクタ８の外周には複数の放熱フィン９が放射状に突 設されている。そして、ポ−ルピ−ス７には図示のように通気孔１３が穿たれ、 この通気孔１３はコレクタ外囲器１０の吸気孔１１に連通している。That is, reference numeral 1 in the drawing is an output cavity of the high frequency acting portion, and an output waveguide 6 is connected to the output cavity 1 and a tuner 2 is provided. The drive part of the tuner 2 is composed of a tuner plate 2a, a tuner rod 3, a screw 4, a bellows 5, and the like. Further, an air-cooled collector 8 is axially connected to the output cavity 1 via a pole piece 7, and a plurality of heat radiation fins 9 are radially projected on the outer periphery of the collector 8. A vent hole 13 is bored in the pole piece 7 as shown in the drawing, and the vent hole 13 communicates with an intake hole 11 of the collector envelope 10.
【０００９】 動作時には、コレクタ外囲器１０の吸気孔１１から冷却風１２が導入され、こ の冷却風１２は複数の放熱フィン９の間を通過してコレクタ８を冷却するが、同 時に冷却風の一部１２ａが通気孔１３を通ってチュ−ナ２の駆動部に回り込み、 冷却する。During operation, cooling air 12 is introduced from the intake holes 11 of the collector envelope 10, and the cooling air 12 passes between the plurality of heat dissipating fins 9 to cool the collector 8. A part of the wind 12a passes through the ventilation hole 13 and wraps around the drive portion of the tuner 2 to cool it.
【００１０】 その結果、チュ−ナ２の温度は図２に示すようになり、従来例に比べ著しく低 下していることが判る。尚、図２における横軸の時間は、高周波を出力してから の時間を示している。As a result, the temperature of the tuner 2 becomes as shown in FIG. 2, and it can be seen that the temperature is significantly lower than that of the conventional example. The time on the horizontal axis in FIG. 2 indicates the time after the high frequency is output.
【００１１】[0011]
以上説明したようにこの考案によれば、ポ−ルピ−スに通気孔が形成され、こ の通気孔を通してコレクタを冷却する冷却風の一部がチュ−ナの駆動部に案内さ れるように構成されているので、チュ−ナの高周波損失による温度上昇が抑制さ れ、大電力動作でもチュ−ナの駆動部の焼き付き等を防止出来る。 As described above, according to the present invention, the vent hole is formed in the pole piece, and a part of the cooling air for cooling the collector is guided to the drive section of the tuner through the vent hole. Since it is configured, the temperature rise due to the high frequency loss of the tuner is suppressed, and it is possible to prevent the seizure of the drive section of the tuner even during high power operation.
