[0033] Figure 1 This is a cross-sectional schematic diagram of an X-ray apparatus according to some embodiments of this application. Please see below. Figure 1 One aspect of this application relates to an X-ray device 50, which includes a housing 1. The X-ray device 50 can be used as an X-ray source, a computed tomography (CT) source, such as a security screening CT source. The housing 1 may be generally rectangular in shape. The internal space of the housing 1 may be filled with a fluid (not shown), which may be a cooling or insulating medium such as air or transformer insulating oil.

[0034] The X-ray device 50 includes an X-ray tube 7 disposed within the housing 1. The X-ray tube 7 can be surrounded and protected by the housing 1. The X-ray tube 7 can be surrounded by fluid, for example, the X-ray tube 7 can be immersed in air or transformer insulating oil.

[0035] Figure 2 for Figure 1 A partial cross-sectional schematic diagram of the X-ray device. (See attached diagram.) Figure 2 As shown, the X-ray tube 7 includes a housing 10, a cathode assembly 11, an anode shank 12, and an anode target 13. The housing 10 may be made of glass. The interior of the housing 10 may be under high pressure or a vacuum atmosphere. The cathode assembly 11 may be at least partially located within the housing 10. The anode target 13 may be located within the housing 10, spaced apart from and opposite to the cathode assembly 11. The anode shank 12 may support the anode target 13 and extend away from the cathode assembly 11.

[0036] The anode shank 12 includes a hollow groove 15 and an opening 68. The hollow groove 15 includes a sealed end 52 and an open end 54, wherein the sealed end 52 is closer to the anode target 13 than the open end 54.

[0037] Figure 3 yes Figure 1 A perspective view of an X-ray device. Figure 4 for Figure 1 Partial fluoroscopic and exploded schematic diagram of the X-ray device. Please refer to [reference needed]. Figure 3 , 4 The X-ray device 50 includes a heat dissipation assembly 9, which includes a hollow tube 16, an anode stalk heat sink 18, an output pipe 19, a fluid heat sink 20, an input pipe 22, and a fluid delivery element 23. The hollow tube 16 includes an output end 56 housed within the hollow groove 15 and spaced apart from the sealed end 52, and an input end 58 communicating with the output end 56. The fluid delivery element 23, the output pipe 19, the fluid heat sink 20, the input pipe 22, the input end 58, the output end 56, and the hollow groove 15 are fluidly connected.

[0038] The hollow tube 16, the output pipe 19, and the input pipe 22 can each be a generally tubular structure in which the fluid can flow. The hollow tube 16 can be inserted into the hollow groove 15 through the open end 54. The output end 56 can be closer to the sealed end 52 than the input end 58.

[0039] The fluid radiator 20 can dissipate heat and cool the fluid inside it. Examples of the fluid radiator 20 may include, but are not limited to, an oil radiator.

[0040] The fluid delivery element 23 can be a machine capable of extracting or pressing in fluids such as liquids or gases, such as a pump.

[0041] In some embodiments, the anode target 13 can generate X-rays under bombardment of the high-speed electron beam of the cathode assembly 11 during operation of the X-ray device 50. The window 3 can filter secondary electrons from the X-rays. A majority, such as 99% or more, of the energy of the electron beam can be converted into heat energy at the anode target 13. This heat energy is transferred to the surrounding medium, such as the anode stem 12, the anode stem heat sink 18, the housing 10, the fluid, thereby causing the X-ray tube 7, the fluid to heat up and increase in temperature. The anode stem heat sink 18 can contact the anode stem 12 and passively dissipate heat from the anode stem 12, the anode target 13 to the surrounding medium, such as the fluid, without requiring additional energy, by virtue of its material and construction, to reduce the temperature of the anode stem 12, the anode target 13.

[0042] In the event that the temperature sensor (not shown) detects that the temperature has risen to a set value, the fluid delivery element 23 can be activated, either automatically or manually, to cause the fluid to flow to actively dissipate heat. The fluid delivery element 23 causes the fluid inside the housing 1 that has been heated by the X-ray tube 7, the anode stem heat sink 18 to be input to the fluid heat sink 20 through the output conduit 19.

[0043] The fluid heat sink 20 can dissipate heat from the fluid flowing through it to cool the fluid by virtue of its material and construction. For example, the fluid heat sink 20 can include a plurality of hollow heat dissipation fins (not shown) that can be provided with a heat-conductive gauze mesh (not shown) therebetween to improve heat dissipation efficiency. The fluid can dissipate heat and reduce in temperature as it flows through the plurality of hollow heat dissipation fins, the heat-conductive gauze mesh.

[0044] The fluid that has been cooled by flowing through the fluid heat sink 20 is caused to flow by the fluid delivery element 23, through the input conduit 22, the input end 58, the output end 56, into the hollow groove 15, towards the closed end 52, to absorb heat from the anode stem 12, the anode target 13, to reduce the temperature of the anode stem 12, the anode target 13.

[0045] The gap 70 between the hollow tube 16 and the hollow groove 15 can be in fluid communication with the opening 68. This can facilitate fluid circulation and improve heat dissipation.

[0046] The gap 70 can include the space between the closed end 52 and the output end 56. The inner wall of the hollow groove 15 can have a size that is greater than the size of the outer wall of the hollow tube 16. The gap 70 can include the space between the inner wall of the hollow groove 15 and the outer wall of the hollow tube 16.

[0047] The fluid flows into the hollow slot 15 along the direction indicated by the first arrow A through the hollow tube 16, and the fluid in the hollow tube 16 can cool the fluid outside the hollow tube 16 and the anode stem 12.

[0048] The opening 68 can be in fluid communication with the hollow slot 15. The opening 68 can communicate the inside of the hollow slot 15 and the outside of the anode stem 12. The fluid outside the hollow tube 16 and inside the gap 70 can absorb the heat of the anode stem 12 and flow out from the inside of the hollow slot 15 to the outside of the anode stem 12 through the opening 68 along the directions indicated by the second arrow B and the third arrow C.

[0049] Embodiments of the present application can help the X-ray device to dissipate heat effectively, have high heat dissipation efficiency, and the like.

[0050] For example, the anode stem heat sink 18 and the fluid heat sink 20 included in the X-ray device 50 can dissipate heat. Moreover, the fluid delivery element 23, the output pipeline 19, the fluid heat sink 20, the input pipeline 22, the input end 58, the output end 56, and the hollow slot 15 can be in fluid communication and can help fluid flow, actively dissipate heat, and further improve heat dissipation capacity on the basis of passive heat dissipation of the anode stem heat sink 18 and the fluid heat sink 20. Meanwhile, the hollow tube 16, the gap 70, and the opening 68 can dissipate heat through fluid, and the fluid heat dissipation area of the X-ray device 50 is large. Therefore, embodiments of the present application can help the X-ray device 50 to dissipate heat effectively, have high heat dissipation efficiency, improve the insulation and the like of the X-ray device 50, reduce the risk of target melting and damage of the X-ray device 50, improve the stability of the X-ray device 50, and / or guarantee the service life of the X-ray device 50.

For example, comparedly, the closer to the center is the inner, the farther from the center is the outer, the closer to the ground is the lower, the farther from the ground is the upper, the closer to the user is the front, the farther from the user is the back, and the like.

[0052] In some embodiments, the fluid heat sink 20 is arranged outside the housing 1. In this way, the fluid heat sink 20 can be facilitated to dissipate heat from outside the housing 1, and the X-ray device 50 can be effectively cooled with a high cooling efficiency. The fluid in the housing 1 can return to the housing 1 after being cooled by the fluid heat sink 20 outside the housing 1, and the temperature of the X-ray tube 7 in the housing 1 can be reduced.

[0053] When the housing 1 is a cuboid, the fluid heat sink 20 can be arranged outside one of the six sides of the housing 1, for example, the fluid heat sink 20 can be arranged above the top side of the housing 1.

[0054] The fluid heat sink 20 can be in contact with or mounted on the housing 1, and can dissipate heat from the housing 1 while dissipating heat from the fluid.

[0055] In some embodiments, the cooling assembly 9 includes a fan 21 arranged outside the housing 1 and adjacent to the fluid heat sink 20. In this way, the fan 21 can be facilitated to dissipate heat from outside the housing 1, promote heat dissipation of the adjacent fluid heat sink 20, and the structure of the X-ray device 50 is compact and small in size.

[0056] The fan 21 can be multiple. The fluid heat sink 20 can be arranged between the fan 21 and the housing 1. The fan 21 can accelerate the cooling of the fluid inside the fluid heat sink 20 by promoting the circulation of the surrounding air, and significantly improve the cooling efficiency.

[0057] In some embodiments, the anode stem 12 includes a main body portion 64 and a necked portion 66 smaller in size relative to the main body portion 64, the sealing end 52 is arranged on the main body portion 64, and the necked portion 66 is closer to the anode target 13 than the main body portion 64. In this way, the anode stem 12 can be facilitated to quickly conduct heat and ensure the service life of the X-ray tube 7.

[0058] The sealing end 52 is arranged on the main body portion 64, and the necked portion 66 can not have the hollow groove 15, and the necked portion 66 can be more robust. The anode target 13 can be arranged at one end of the necked portion 66 close to the cathode assembly 11, and the main body portion 64 can extend from the end of the necked portion 66 away from the anode target 13 to a direction away from the anode target 13. The heat of the anode target 13 can be transferred to the main body portion 64, the fluid in the hollow groove 15, etc. through the necked portion 66.

[0059] In some embodiments, the X-ray tube 7 comprises an anode cover 14, which covers the constricted portion 66 and the anode target 13, and is adjacent to the main body portion 64. In this way, heat can be conducted quickly, and the service life of the X-ray tube 7 can be ensured.

[0060] The anode cover 14 can at least partially cover the constricted portion 66 and the portion of the anode target 13 exposed inside the housing 10. The anode cover 14 can be located at one end between the anode target 13, the constricted portion 66 and the cathode assembly 11, and at the other end between the constricted portion 66 and the portion of the main body portion 64 beyond the constricted portion 66, and abuts the portion of the main body portion 64 beyond the constricted portion 66.

[0061] The anode cover 14 can function to block scattered radiation, shield scattered secondary electrons and / or dissipate heat.

[0062] The anode cover 14, the anode target 13 and the anode stem 12 can constitute an anode assembly (not numbered) of the X-ray tube 7.

[0063] In some embodiments, the extension direction of the opening 68 is not parallel to the extension direction of the hollow tube 16. In this way, fluid circulation flow can be facilitated, and heat dissipation capacity can be improved.

[0064] The angle between the extension direction of the opening 68 and the extension direction of the hollow tube 16 can not be equal to 0 degrees. The angle between the extension direction of the opening 68 and the extension direction of the hollow tube 16 can be greater than 0 degrees.
