Reference numeral 31 is a tube container made of cast aluminum alloy, and an X-ray tube 32 is housed in the tube container 31. The X-ray tube 32 includes an anode 33, a cathode 34, and a vacuum valve 35 accommodating the anode 33 and the cathode 34. The anode 33 is composed of an anode target 33a and a rotor 33b.

The space between the X-ray tube 32, the field coil 35 and the like and the tube container 31 is filled with a liquid insulating oil for ensuring electrical insulation of each component and for cooling. There is. Note that the insulating oil used to cool the X-ray tube, etc.

When the heat exchanger 38 is used in this way, the heat exchanger 38 cannot be installed close to the X-ray tube device because the heat exchanger 38 generates noise. Therefore, the X-ray tube device and the heat exchanger 38 are connected by a hose of about 30 to 40 m, and the heat exchanger 38 is separated from the X-ray tube device. In FIG. 3, X

In the X-ray tube device having the above structure, thermoelectrons are emitted from the cathode 34.

As another method for cooling the X-ray tube apparatus, there is a method in which a resin in which a high thermal conductive filler is dispersed is arranged between the constituent members of the X-ray tube which generate heat (Japanese Patent Laid-Open No. Hei 10-1999) 6-267690).

In the conventional X-ray tube device, a heat-resistant epoxy resin having a large heat capacity is usually used alone as a material for the support. Also,
The insulating oil used as a medium for insulating the support also has a low thermal conductivity. Therefore, the cooling efficiency of the X-ray tube device is low.

Therefore, when an X-ray tube device is used for a medical diagnostic apparatus, the temperature rises greatly as the working time for photographing or the like becomes long, and the heat dissipation amount of the X-ray tube device becomes insufficient. Therefore, the insulating oil that has cooled the X-ray tube device is sent to the heat exchanger to increase the cooling capacity of the X-ray tube device.

However, in the case of a structure utilizing a heat exchanger,
Since the noise of the heat exchanger is large, the heat exchanger cannot be brought close to the X-ray tube device, and a hose is connected between the X-ray tube device and the heat exchanger. In this case, when air bubbles enter from the X-ray tube device or the connection between the heat exchanger and the hose, the withstand voltage characteristic of the X-ray tube device deteriorates due to this. Also,
Insulating oil is filled between the X-ray tube device, the hose, and the heat exchanger, making it difficult to separate them. Therefore, even if one of the X-ray tube device, the hose, and the heat exchanger fails, all of them must be replaced, which is disadvantageous in terms of cost. Further, the insulating oil functions as a refrigerant, but at the same time, an insulating function is required. Therefore, since the material cannot be selected only from the aspect of the refrigerant function, a material having low heat exchange efficiency is also used. Therefore, even if the efficiency of heat exchange from oil to air in the heat exchanger is high, the efficiency of heat exchange from the X-ray tube to the oil performed by the X-ray tube device is low, and the overall heat exchange efficiency is low.

According to the present invention, there is provided an X-ray tube having an anode target and a cathode arranged in a vacuum valve, a field coil for rotating the anode target, the X-ray tube and the field coil. In an X-ray tube device including a tube container for storing the X-ray tube, at least a partial region of a space sandwiched between the tube container and the X-ray tube has a lower layer portion located on the X-ray tube side. Contacting the outer periphery of the tube container, the surface of the upper layer portion located on the tube container side is uneven, and one side in the tube axis direction of the X-ray tube between the recessed part and the inner surface of the tube container. To the other side, a resin layer is provided in which a passage for the refrigerant is formed.

The X-ray tube has an anode target and a cathode arranged in a vacuum valve, a field coil for rotating the anode target, and a tube container accommodating the X-ray tube and the field coil. In the X-ray tube device described above, the X-ray tube and the field coil are embedded inside, and
The surface of the upper layer portion located on the side of the pipe container is uneven, and the X portion is formed between the concave portion and the inner surface of the pipe container.
A resin layer is provided in which a refrigerant passage is formed from one side to the other side in the tube axis direction of the wire tube.

Further, the structure of the resin layer is such that, when the resin layer is sectioned in a direction perpendicular to the tube axis of the X-ray tube, the inside has a circular shape and a predetermined wall thickness, and the outside has a circumferential direction. It has a pleated shape with irregularities.

According to the above construction, the high pressure portion of the X-ray tube device is covered with the resin. Therefore, the withstand voltage characteristic does not deteriorate even if air, dust, or the like enters the inside of the X-ray tube device. In this case, even if only a part of the X-ray tube device is covered with resin, a corresponding effect can be obtained. However, if the high-voltage portion such as the X-ray tube or the field coil is completely covered with resin, the effect is further enhanced.

Further, a passage is formed on the surface of the resin layer between the resin container and the pipe container. Therefore, the heat exchange efficiency can be improved by causing the cooling medium to flow through the passage portion. At this time, since the high voltage portion is insulated by the resin, it is not necessary to consider the insulating property as the cooling medium. Therefore, the material can be selected in terms of cooling characteristics, the material having high heat exchange efficiency can be selected, and the heat exchange efficiency can be improved. Further, since the surface of the resin layer has irregularities and the surface area is large, the heat exchange efficiency between the resin layer and the cooling medium is also improved.
For example, by making the surface of the resin layer pleated, the heat exchange rate from the X-ray tube or field coil to the refrigerant can be improved by 5 to 10 times, and a compact and highly efficient X-ray tube device can be realized.
