[0023] The X-ray tube body 1 is installed on the X-ray tube fixing socket 7, and a spiral cooling coil 8 is wound on the outer wall of the X-ray tube body 1. One end of the spiral cooling coil 8 is connected with the water inlet pipe 9, and the other end of the spiral cooling coil 8 is connected with the water outlet pipe 10. The spiral cooling coil 8 is wound on the outer wall of the X-ray tube body 1, one end is connected with the water inlet pipe 9, and the other end is connected with the water outlet pipe 10. During operation, cooling water (or other suitable cooling medium) flows into the spiral cooling coil 8 from the water inlet pipe 9. During the flow in the coil, the cooling medium is heated by absorbing the heat generated by the X-ray tube body 1 through heat conduction, and then flows out of the water outlet pipe 10, thereby realizing effective cooling of the X-ray tube body 1.
