In view of the foregoing, a first aspect of the present application provides an anode structure of an X-ray tube, the anode structure 1 including a target disk 10, a die holder 20, a cooling sleeve 40, and a housing 30, referring to fig. 1 and 2. The target disk 10 is adapted to be bombarded by electron flow and is disposed at one end of the die holder 20. The cooling shaft sleeve 40 comprises a heat collecting section 41 and a heat dissipating section 42, wherein the heat collecting section 41 is provided with a heat collecting cavity 41A, one end of the tube core support 20, which is far away from the target disc 10, is connected with the heat collecting section 41 and is at least partially positioned in the heat collecting cavity 41A, the heat dissipating section 42 is connected with the heat collecting section 41, and a liquid cooling pipeline 42A is arranged in the heat dissipating section 42. The housing 30 has a receiving cavity (not identified in the figures) in which the target disk 10, the die holder 20, and the cooling sleeve 40 are disposed.
Structurally, the die holder 20 receives a large amount of heat from the target disk 10, and the heat is rapidly transferred to the cooling sleeve 40 through a part of the structure in the heat collecting cavity 41, and the cooling sleeve 40 discharges the heat by using a liquid cooling pipeline 42A on the surface or in the cooling sleeve 40, so that the accumulation of the heat in the anode structure 1 is reduced. The housing 30 accommodates the above-described structure therein, and plays a role of supporting and protecting.
It should be noted that the description of the "heat collecting section" or the "heat dissipating section" is only for the convenience of those skilled in the art to understand that, for example, the surface of the heat collecting section 41 also has a heat dissipating function, and thus, the function of the structure is not to be understood as being limited to this or a special requirement on the material structure thereof, thereby limiting the present application.

The rotor 21 can rotate under the drive of power and drives the target disk 10 to rotate, so that the parts of the target disk 10 which bear the bombardment of electron flow are continuously and circularly changed, the utilization rate of materials is improved, and the probability of burning the anode structure 1 caused by excessive heat concentration is also reduced.
