Description

Technical Field

[0001] This utility model relates to the field of X-ray tube technology, specifically to an X-ray tube anode cooling structure. Background Technology

[0002] An X-ray tube is a vacuum diode that operates at high voltage. It contains two electrodes: a filament that emits electrons, serving as the cathode, and a target that receives the electrons, serving as the anode. Both electrodes are sealed within a high-vacuum glass or ceramic housing.

[0003] In an X-ray tube, the anode plays a crucial role. It not only acts as a conductor, receiving and conducting electrons emitted from the cathode to the cable and back to the high-voltage generator, but also provides essential mechanical support for the X-ray target. Simultaneously, the anode is also a highly efficient heat radiator, effectively and rapidly dissipating the heat generated by the interaction of electrons with the anode. However, properly managing this heat, especially for high-capacity X-ray tubes, has always been a significant challenge for engineers, thus necessitating an X-ray tube anode cooling structure.
