この考案はＸ線管を容器（ハウベ）内に収容し
たＸ線管装置に関する。[Detailed Description of the Invention] This invention relates to an X-ray tube device in which an X-ray tube is housed in a container (Haube).
周知の通りＸ線管はハウベと称される密閉容器
内に取付けられ、容器内には絶縁油、絶縁ガス等
の絶縁、冷却媒体が充填される。 As is well known, the X-ray tube is installed in a closed container called a Haube, and the container is filled with insulation and cooling media such as insulating oil and gas.
即ち、従来のＸ線管装置は第１図に示すように
構成され、容器１内にはＸ線管２が収容されると
共に冷却を兼ねる絶縁油３が充填されている。こ
の場合、Ｘ線管２を容器１に取付けるに当つて
は、図示していないが容器１内面のねじ受け用突
起に漏斗状の絶縁体４がねじにより固着されてい
る。この絶縁体４にＸ線管２の一端が嵌合され、
更にローター５を駆動するステータ６がねじ（図

尚、図中７は絶縁体４に複数個穿つた自然対流に
よる絶縁油３の移動孔である。 That is, the conventional X-ray tube apparatus is constructed as shown in FIG. 1, in which an X-ray tube 2 is housed in a container 1 and is filled with insulating oil 3 which also serves as cooling. In this case, when attaching the X-ray tube 2 to the container 1, a funnel-shaped insulator 4 is fixed to a screw receiving projection on the inner surface of the container 1 with a screw (not shown). One end of the X-ray tube 2 is fitted into this insulator 4,
Furthermore, a stator 6 for driving the rotor 5 is fixed to the side wall of the insulator 4 with screws (not shown).
In the figure, reference numeral 7 indicates a plurality of holes drilled in the insulator 4 for movement of the insulating oil 3 by natural convection.
ところが上記のような従来のＸ線管装置におい
ては、Ｘ線管２のローター５を回転させるステー
タ６は、動作することにより数百ワツトの熱を発
生させる。この熱は冷却を兼ねる絶縁油３に伝達
されるが、この絶縁油３は伝達率が非常に悪い。
しかもＸ線管２のターゲツトから大きな熱が発生
するので、容器１の循環しない絶縁油３は熱発生
部分だけが異状に温度が高くなる。従つて、ステ
ータ６周辺の温度は非常に温度が高くなり、ステ
ータ自身の温度が異状に上昇し、その結果、ステ
ータ６の寿命が短かくなるという欠点がある。 However, in the conventional X-ray tube device as described above, the stator 6 that rotates the rotor 5 of the X-ray tube 2 generates several hundred watts of heat as it operates. This heat is transferred to the insulating oil 3 which also serves as cooling, but this insulating oil 3 has a very poor transfer rate.
Moreover, since a large amount of heat is generated from the target of the X-ray tube 2 , the temperature of the non-circulated insulating oil 3 in the container 1 becomes abnormally high only in the heat-generating portion. Therefore, the temperature around the stator 6 becomes extremely high, and the temperature of the stator itself rises abnormally, resulting in a drawback that the life of the stator 6 is shortened.

置を提供することを目的とする。 The object of this invention is to provide an X-ray tube device that eliminates the above-mentioned conventional drawbacks.

In the figure, 9 is a pump motor, 10 is a pump blade, and 11 is a pump oil suction port. Furthermore, a heat exchanger 12 is provided integrally with the container 1 on the outside of the lid 1a.
This heat exchanger 12 is constructed, for example, as shown in FIGS. 3a and 3b, in which corrugated fins 14 are disposed between meandering portions of a meandering insulating oil inflow path 13. A fan 15 is provided adjacent to the heat exchanger 12 , and a cover 16 is provided so as to surround the fan 15 and the heat exchanger 12 , and is integrally attached to the container 1. This cover 16 is provided with an air inflow hole 17 facing the fan 15,
Air outflow holes 18 and 19 are bored on the sides.
Further, an inflow pipe 20 and an outflow pipe 21 are protruded from both ends of the heat exchanger 12 , respectively.
The inflow pipe 20 passes through the lid 1a of the container 1 and is connected to the pump 8 , and the outflow pipe 21 passes through the lid 1a of the container 1.
The stator 6 passes through the lid 1a and the insulator 4.
It extends close to. In addition, the symbols 1b, 1 in the figure

On the other hand, air is sent from the air inflow hole 17 to the fan 15 and hits the fin 14 to cool the insulating oil that has entered the heat exchanger 12 . Furthermore, the cooled insulating oil 3 is sprayed onto the stator 6 through the outflow pipe 21 to cool the stator 6.
