Abstract

The present invention relates to an X-ray apparatus comprising an electron radiation source which generates an electron to an anode, a shaft which rotatably supports the anode, a stator which generates a force to rotate a rotor shaft, an enclosure which maintains at least the anode, electron radiation source and rotor shaft in vacuum, and a housing which contains a cooling medium around the enclosure. The X-ray apparatus is characterized in that an electric wire material to supply power to the electron radiation source and stator, or a connector used for connection with the electric wire material is molded by a material having an electrical insulating property.

Claims (33)

1. An X-ray apparatus comprising:

an anode target which generates X-rays;

an electron radiation source which generates an electron to the anode target;

a rotor which is connected to the anode target;

a stator coil which generates a driving force to rotate the rotor;

an enclosure which maintains at least the anode target, electron radiation source and rotor in a specified vacuum;

a housing around the enclosure which contains a cooling medium that contains water as a main component; and

an electric wire material which supplies power to the stator coil,

wherein a molding material is provided at a specified position to prevent the cooling medium from contacting the electric wire material.

2. The X-ray apparatus according to claim 1 , wherein the molding material includes a resin having an electrical insulating property.

3. The X-ray apparatus according to claim 2 , wherein the molding material includes an electrical insulating material to increase thermal conductivity.

4. The X-ray apparatus according to claim 1 , wherein the cooling medium includes a mixture of glycol including water as a main component.

5. The X-ray apparatus according to claim 1 , wherein the cooling medium is cooled and circulated by a cooling unit.

6. The X-ray apparatus according to claim 5 , wherein the cooling medium is circulated in the vicinity of at least the anode target and electron radiation source.

7. An X-ray apparatus comprising:

a rotary anode target;

an electron radiation source which generates an electron to the rotary anode target;

a rotor which is connected to the rotary anode target;

a stator coil which generates a driving force to rotate the rotor;

an enclosure which maintains at least the rotary anode target, electron radiation source and rotor in specified vacuum;

a housing which contains a cooling medium, that includes water as a main component, around the enclosure;

an electric wire material which supplies power to the stator coil, or a connector used for connection with the electric wire material; and

a molding material which prevents the cooling medium from contacting the electric wire material and/or any area of the stator coil.

8. The X-ray apparatus according to claim 7 , wherein the cooling medium is cooled and circulated by a cooling unit.

9. The X-ray apparatus according to claim 8 , wherein the cooling medium is circulated in the vicinity of at least the rotary anode target and electron radiation source.

10. An X-ray apparatus comprising:

a rotary anode target; an electron radiation source which generates an electron to the rotary anode target;

a rotor which is connected to the rotary anode target;

a stator coil which generates a driving force to rotate the rotor;

an enclosure which maintains at least the rotary anode target, electron radiation source and rotor in specified vacuum;

a housing which contains a cooling medium, that includes water as a main component, around the enclosure; and

an electric wire material which supplies power to the stator coil, or a connector used for connection with the electric wire material,

wherein the electric wire material and/or any area of the stator coil is molded by a material having electrical insulating property.
