Description

Technical Field

[0001] The utility model relates to the technical field of X-ray tubes, and specifically relates to an anode head assembly of an anode target of an X-ray tube. Background Art

[0002] The anode head assembly of the anode target of the X-ray tube is a crucial part in the X-ray tube. It directly participates in the X-ray generation process. The anode head assembly mainly consists of an anode head, a target surface, an anode cover, a glass ring, an anode stem, etc. These parts cooperate together to ensure that the X-ray tube can work stably and efficiently.

[0003] In the existing anode head assembly of the anode target of the X-ray tube, it is inconvenient to set a heat dissipation structure inside the anode head at the rear end of the target surface. As a result, the heat dissipation of the target surface solely depends on the anode head itself, leading to an ineffective heat dissipation effect. For this reason, we propose an anode head assembly of an anode target of an X-ray tube. Summary of the Utility Model

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] For this reason, the technical solution adopted by the utility model is as follows:

[0006] An anode head assembly of an anode target of an X-ray tube, comprising: an anode assembly, a heat dissipation assembly; the anode assembly includes an anode head, a target surface installed at the front end of the anode head, an anode cover installed at the outer end of the anode head, an anode stem and a glass ring respectively installed at the rear end of the anode head; the heat dissipation assembly includes a heat conducting block fixedly installed inside the anode head, a first installation cavity opened inside the anode head at the rear end of the heat conducting block, a second installation cavity opened inside the anode stem, a heat conducting column fixedly installed at the rear end of the heat conducting block, a first heat dissipation ring fixedly installed at the outer end of the anode head, and a second heat dissipation ring fixedly installed at the outer end of the anode stem.

[0007] Preferably, a plurality of groups of first heat dissipation openings and second heat dissipation openings are respectively arranged in the anode head and the anode stem in a row, and the first heat dissipation openings and the second heat dissipation openings are arranged in a circular pattern.

[0008] Preferably, first heat conducting sheets and second heat conducting sheets are respectively movably installed in the first heat dissipation openings and the second heat dissipation openings.

[0009] Preferably, both ends of the first heat conducting sheet are respectively kept in contact with the heat conducting column and the first heat dissipation ring, and both ends of the second heat conducting sheet are respectively kept in contact with the heat conducting column and the second heat dissipation ring.

[0010] Preferably, both the first heat dissipation ring and the second heat dissipation ring are of a cylindrical structure.

[0011] By adopting the above technical solution, the beneficial effects obtained by the utility model are as follows:

[0012] In this utility model, when the X-ray tube is working, the electron flow emitted by the cathode flies at high speed towards the target surface inside the anode head under the action of the electric field. When the electron flow bombards the target surface, the kinetic energy of a small amount of electron flow is converted into X-ray energy, and the rest is converted into heat energy. A large amount of heat will be generated on the target surface, resulting in an increase in the working temperature. After the temperature of the target surface rises, the heat conducting block and heat conducting column at its rear end will conduct heat, so that the heat on the target surface is quickly transferred to the first heat dissipation ring and the second heat dissipation ring at the outer end through multiple groups of first heat conducting sheets and second heat conducting sheets at the outer end of the heat conducting column, thereby quickly conducting and dissipating the heat on the target surface and ensuring the high efficiency of the heat dissipation of the target surface.

It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.

[0019] The following describes an anode head assembly of an anode target of an X-ray tube provided by some embodiments of the present utility model in conjunction with the accompanying drawings.

[0021] Combined with Figure 1-2As shown in the figure, an anode head assembly of an X-ray tube anode target provided by the present utility model includes: an anode assembly 100 and a heat dissipation assembly 200; the anode assembly 100 includes an anode head 101, a target surface 102 installed at the front end of the anode head 101, an anode cover 103 installed at the outer end of the anode head 101, an anode stem 104 and a glass ring 105 respectively installed at the rear end of the anode head 101; the heat dissipation assembly 200 includes a heat conduction block 201 fixedly installed inside the anode head 101, a first installation cavity 202 opened inside the anode head 101 at the rear end of the heat conduction block 201, a second installation cavity 203 opened inside the anode stem 104, a heat conduction column 204 fixedly installed at the rear end of the heat conduction block 201, a first heat dissipation ring 205 fixedly installed at the outer end of the anode head 101, a second heat dissipation ring 206 fixedly installed at the outer end of the anode stem 104. A plurality of groups of first heat dissipation openings 207 and second heat dissipation openings 209 are respectively arranged in the anode head 101 and the anode stem 104 in an array, and the first heat dissipation openings 207 and the second heat dissipation openings 209 are arranged in a circular pattern. First heat conduction sheets 208 and second heat conduction sheets 210 are respectively movably installed in the first heat dissipation openings 207 and the second heat dissipation openings 209. Both ends of the first heat conduction sheet 208 are kept in contact with the heat conduction column 204 and the first heat dissipation ring 205 respectively, and both ends of the second heat conduction sheet 210 are kept in contact with the heat conduction column 204 and the second heat dissipation ring 206 respectively. Both the first heat dissipation ring 205 and the second heat dissipation ring 206 are of a cylindrical structure.

[0022] Specifically, the anode head assembly of the X-ray tube anode target is a crucial part of the X-ray tube. It directly participates in the X-ray generation process. The anode head assembly is mainly composed of an anode head 101, a target surface 102, an anode cover 103, a glass ring 105, an anode stem 104, etc.; when the X-ray tube is working, the electron flow emitted by the cathode flies at high speed towards the target surface 102 inside the anode head 101 under the action of the electric field. When the electron flow bombards the target surface 102, a small amount of the kinetic energy of the electron flow is converted into X-ray energy, and the rest is converted into heat energy. A large amount of heat will be generated on the target surface 102, resulting in an increase in the working temperature. After the temperature of the target surface 102 rises, the heat conduction block 201 and the heat conduction column 204 at its rear end will conduct heat, so that the heat on the target surface 102 is quickly transferred to the first heat dissipation ring 205 and the second heat dissipation ring 206 at the outer end through a plurality of groups of first heat conduction sheets 208 and second heat conduction sheets 210 at the outer end of the heat conduction column 204, thereby quickly conducting and dissipating the heat on the target surface 102 and ensuring the high efficiency of heat dissipation of the target surface 102.

[0023] The working principle and usage process of the present utility model:

[0024] When the inner target surface 102 of the anode head 101 is at a high temperature during operation, the heat conduction block 201 at the rear end of the target surface 102 will conduct the heat on the target surface 102 to the heat conduction column 204 at the rear end. Through multiple groups of first heat conduction fins 208 and second heat conduction fins 210 arranged annularly at the front and rear ends of the heat conduction column 204, the heat is conducted to the first heat dissipation ring 205 and the second heat dissipation ring 206 at the outer ends of the anode head 101 and the anode handle 104 for external heat dissipation, so as to quickly and efficiently conduct and dissipate the heat generated during the operation of the target surface 102 and improve the efficiency of heat dissipation of the target surface 102.
