Description

Technical Field

[0001] This utility model relates to the field of accelerator tube technology, specifically to a diamond sheet for an electronic window, a ray tube, and an electron accelerator. Background Technology

[0002] In modern technology, X-ray tubes, as key components of numerous electronic devices, are widely used in medical imaging, scientific research, and industrial inspection. The electron window is a crucial component in the X-ray tube responsible for transmitting the electron beam, and its performance directly affects the tube's stability and lifespan. However, in related technologies, the electron window generates a significant amount of heat during operation. If this heat cannot be dissipated effectively and promptly, the electron window's temperature will rise, thus affecting its normal operation. Utility Model Content

[0003] This utility model is based on the inventor's discovery and understanding of the following facts and problems:

[0004] During operation, electron windows must continuously withstand the intense bombardment of high-energy electron beams emitted from a radiation source. These high-energy electron beams are not only fast and energetic but also extremely dense, posing a severe challenge to the electron windows. When electrons in the beam collide with atoms in the electron window material, they transfer their energy to these atoms. Due to the extremely high energy of the electron beam, these collisions cause violent atomic motion within the electron window material, generating a large amount of heat. This heat accumulates rapidly within the electron window and attempts to dissipate to the surrounding environment through thermal conduction, convection, or radiation.

[0005] However, due to the relatively small surface area of ​​the electronic window and its often tightly surrounded by other components, heat dissipation is relatively poor. This results in the electronic window being unable to dissipate the generated heat effectively and in a timely manner during operation, causing heat to accumulate inside the electronic window and eventually leading to high-temperature problems.

[0006] Therefore, an embodiment of this utility model proposes a diamond sheet for electronic windows, which includes a middle plate and an edge plate connected to each other. The edge plate is wrapped around the outside of the middle plate in a ring shape. The thickness of the edge plate is greater than the thickness of the middle plate. A transition surface is provided at the connection between the edge plate and the middle plate. The transition surface is one or a combination of one or more of the following: inclined slope, arc slope, and step.

[0007] In summary, the diamond sheet for electronic windows provided by this utility model not only significantly improves the heat dissipation efficiency of the diamond sheet by setting a transition surface at the connection between the middle plate and the edge plate, and setting the transition surface as one or more of the following: inclined slope, arc slope, and step shape, but also greatly enhances its structural strength and durability.

[0008] In some embodiments, the transition surface is stepped, and the transition surface is divided into single-step and multi-step. When the thickness ratio of the middle plate to the edge plate is greater than 1 / 3, the transition surface is set to single-step; when the thickness ratio of the middle plate to the edge plate is less than 1 / 3, the transition surface is set to multi-step.

[0009] In some embodiments, the transition surface is provided as an inclined slope, and the angle between the inclined surface where the transition surface is located and the horizontal plane where the intermediate plate is located is 100° to 130°.

[0010] In some embodiments, the intermediate plate has a first surface and a second surface disposed opposite to each other, the edge plate has a third surface and a fourth surface disposed opposite to each other, the first surface and the third surface are flush, and the transition surface is disposed at the junction of the second surface and the fourth surface.

[0011] In some embodiments, in the thickness direction of the diamond sheet for the electronic window, the intermediate plate is located at the middle position of the edge plate, and there are two transition surfaces, which are symmetrically arranged on both sides of the intermediate plate.

[0012] In some embodiments, the electronic window is made of a circular diamond sheet, and the middle plate and the edge plate are integrally formed.

[0013] In addition, one embodiment of this utility model also provides a window, which includes the diamond sheet for electronic windows described above.

[0014] In one embodiment of this utility model, an X-ray tube is also provided, the X-ray tube comprising an upper waveguide, a lower waveguide, and the aforementioned diamond sheet for an electronic window, the diamond sheet for the electronic window being sandwiched between the upper waveguide and the lower waveguide.

[0015] In some embodiments, the upper waveguide or the lower waveguide is provided with a positioning groove, and the electronic window is provided with a diamond sheet in the positioning groove.

[0016] In addition, one embodiment of the present invention also provides an electron accelerator, which includes the X-ray tube described in the above embodiment. Attached Figure Description

[0026] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] like Figures 1 to 7 As shown, this utility model provides a diamond sheet 10 for electronic windows, which includes a middle plate 11 and an edge plate 12 connected to each other. The edge plate 12 is wrapped around the outside of the middle plate 11 in a ring shape. The thickness of the edge plate 12 is greater than the thickness of the middle plate 11. A transition surface 13 is provided at the connection between the edge plate 12 and the middle plate 11. The transition surface 13 is a combination of one or more of the following: inclined slope, arc slope, and step shape. This not only improves heat dissipation performance but also enhances structural strength.

[0028] Specifically, the edge plate 12 has a ring-shaped structure, tightly wrapping around the periphery of the middle plate 11, and the edge plate 12 has a thickness difference compared to the middle plate 11, which can effectively increase the heat dissipation area. In other words, when the diamond sheet generates heat during operation, this heat can be dissipated more efficiently through the connection area between the middle plate 11 and the edge plate 12, thereby ensuring that the diamond sheet can work continuously and stably, avoiding performance degradation or damage due to overheating.

[0029] Furthermore, the transition surface 13 is not a simple straight transition, but rather a clever combination of one or more of the following: inclined slope, arc slope, and step shape. This allows the diamond sheet to maintain its structural integrity and stability even when facing complex and changing stress environments during long-term use.

[0030] In summary, the diamond sheet 10 for electronic windows provided by this utility model, by setting a transition surface 13 at the connection between the middle plate 11 and the edge plate, and setting the transition surface 13 as one or more of the inclined slope, arc slope and step shape, not only significantly improves the heat dissipation efficiency of the diamond sheet, but also greatly enhances its structural strength and durability.

[0031] In some embodiments, such as Figure 2 and Figure 3 In the first and second embodiments shown, the transition surface 13 can be configured as a step, which can be either a single-step or multi-step. When the thickness ratio of the middle plate 11 to the edge plate 12 is greater than 1 / 3, the transition surface 13 is configured as a single-step; when the thickness ratio of the middle plate 11 to the edge plate 12 is less than 1 / 3, the transition surface 13 is configured as a multi-step.

[0032] Specifically, when the thickness ratio of the intermediate plate 11 to the edge plate 12 is greater than 1 / 3, the transition surface 13 is designed as a single step to consider structural strength and smoothness of transition. This design simplifies the processing flow, reduces manufacturing costs, and allows the diamond sheet to distribute stress more evenly when subjected to external forces, thus improving overall durability and reliability while ensuring sufficient strength. Figure 2 The diamond sheet 10 for the electronic window in the first embodiment shown has a single-step design for its transition surface 13, which ensures sufficient structural support while maintaining a thin and light profile.

[0033] When the thickness ratio of the intermediate plate 11 to the edge plate 12 is less than 1 / 3, the transition surface 13 adopts a multi-step design. Through multiple gradually changing steps, a smooth transition is achieved from the thicker edge plate 12 to the thinner intermediate plate 11, effectively dispersing stress, reducing the potential crack risk caused by abrupt thickness changes, and more effectively alleviating stress concentration, thereby improving the crack resistance and service life of the diamond sheet. Figure 3 The transition surface 13 of the diamond sheet 10 for the electronic window in the second embodiment shown is multi-step.

[0034] Furthermore, when the thickness ratio of the intermediate plate 11 to the edge plate 12 is less than 1 / 5, to avoid unnecessary processing complexity and increased costs, while ensuring the stability of the diamond sheet's performance, the transition surface 13 is usually designed to avoid a multi-step shape. However, when the thickness ratio of the intermediate plate 11 to the edge plate 12 is between 1 / 3 and 1 / 5, i.e., when the thickness difference is moderate, the advantages of the multi-step transition surface 13 become apparent. It can not only effectively disperse stress and improve the crack resistance and service life of the diamond sheet, but also find a good balance between processing accuracy and material cost, ensuring that the overall performance of the diamond sheet reaches its optimal level.

[0035] In some embodiments, such as Figure 4 and Figure 5 In the third and fourth embodiments shown, the transition surface 13 can be configured as an inclined slope, which can be either a single-slope or multi-slope shape. This not only gives the diamond sheet a smoother outer tube but also improves its structural strength. Figure 4 In the third embodiment shown, the single-sloping transition surface 13 facilitates the transition from the intermediate plate 11 to the edge plate 12, which is relatively easy to process and can effectively disperse stress, improving the crack resistance and service life of the diamond sheet. Figure 5 The multi-sloping transition surface 13 in the fourth embodiment shown achieves a more complex stress transition through the combination of multiple continuous slopes, thereby exhibiting better performance when dealing with extreme stress conditions.

[0036] The angle between the inclined surface of the transition surface 13 and the horizontal plane of the intermediate plate 11 is between 100° and 130°. It should be noted that if the angle is too small, the inclined surface may be too steep, causing stress concentration in the transition area and increasing the risk of cracking or damage to the diamond sheet. Conversely, if the angle is too large, the inclined surface may be too gentle. While this can disperse stress, it may increase the overall volume and weight of the diamond sheet, hindering its development towards lightweight and high-efficiency designs. An angle of 100° to 130° ensures that the diamond sheet maintains its structural integrity and stability when subjected to various external forces.

[0037] In some embodiments, such as Figure 6In the fifth embodiment shown, in the thickness direction of the diamond sheet 10 for the electronic window, the intermediate plate 11 is located in the middle of the edge plate 12, and two transition surfaces 13 are provided, symmetrically arranged on both sides of the intermediate plate 11. This allows for a smoother and more gradual transition from the intermediate plate 11 to the edge plate 12, more effectively dispersing and alleviating the pressure generated by external stress, preventing the diamond sheet from cracking or breaking under extreme conditions, thereby significantly improving its structural strength and reliability. Furthermore, the symmetrical arrangement of the two transition surfaces 13 ensures the balance of the diamond sheet under stress, avoiding performance degradation or damage caused by uneven stress distribution.

[0038] In some embodiments, such as Figure 7 In the sixth embodiment shown, the middle plate 11 has a first surface 111 and a second surface 112 disposed opposite to each other, and the edge plate 12 has a third surface 121 and a fourth surface 122 disposed opposite to each other. The first surface 111 and the third surface 121 are flush, and the transition surface 13 is provided at the connection between the second surface 112 and the fourth surface 122. That is to say, Figure 7 In the sixth embodiment shown, the diamond sheet 10 for the electronic window has an asymmetrical shape, that is, the first surface 111 of the intermediate plate 11 is flush with the third surface 121 of the edge plate 12, so that one side of the intermediate plate 11 is flush with the edge plate 12, ensuring the continuity and consistency of the diamond sheet in a certain dimension, which helps to reduce stress concentration and improve the overall structural stability. There is a thickness difference between the second surface 112 of the intermediate plate 11 and the fourth surface 122 of the edge plate 12, and a transition surface 13 is provided at the connection between the second surface 112 and the fourth surface 122, realizing a smooth transition from the intermediate plate 11 to the edge plate 12, effectively dispersing the stress generated by the thickness difference, and avoiding cracking or damage of the diamond sheet due to stress concentration.

[0039] In this embodiment of the invention, the diamond sheet 10 for the electronic window is circular, and the middle plate 11 and the edge plate 12 are integrally formed, ensuring a seamless connection between the middle plate 11 and the edge plate 12 and avoiding performance degradation or damage due to weak connection. The integrally formed design also enables the diamond sheet to exhibit more uniform and stable performance under stress, further improving its durability and impact resistance.

[0040] In addition, this utility model embodiment also provides a window, which includes the diamond sheet 10 for electronic windows provided in the above embodiment.

[0041] This utility model embodiment also provides an X-ray tube, which includes an upper waveguide, a lower waveguide, and a diamond sheet 10 for an electronic window provided in the above embodiment.

This not only helps to reduce the loss of X-rays during transmission and improve the transmission efficiency of X-rays, but also effectively prevents X-ray leakage and ensures the safety and reliability of the X-ray tube.

[0042] Furthermore, a positioning groove is provided on the upper or lower waveguide, and the diamond sheet 10 for the electronic window is placed in the positioning groove, so that the diamond sheet can be easily aligned during installation without tedious adjustments and calibrations, thereby greatly simplifying the installation process and improving work efficiency.

[0043] This utility model embodiment also provides an electron accelerator, which includes the X-ray tube provided in the above embodiment.
