Title:
X-RAY TUBE
Document Type and Number:
WIPO Patent Application WO/2017/028473
Kind Code:
A1
Abstract:
An X-ray tube (100) comprises a rotor shaft (106); a rotor seat (108), which is an integral structure, electrically conductive and thermally insulating, and connected to the rotor shaft in a fixed manner; a bearing (104), which is connected in a fixed manner to the rotor seat. The X-ray tube increases the radiative cooling capability of the anode, and reduces the thermal effect on the rotor and bearing. The anode can be used at a high temperature, so that the entire anode can be made of TZM molybdenum alloy with no need for graphite brazing. Compared with X-ray tubes having fixed-anode, the X-ray tube has a relatively high short-time pulse power and small size, and compared with large-size rotary tubes, has a relatively high continuous power.
