[0001] The present application relates to the technical field of accelerating tubes, and in particular to an accelerating tube water cooling structure and a cooling water channel assembly. Background Art

[0002] The accelerating tube is a key component of the electron linear irradiation accelerator, which can accelerate the electron beam incident from the electron gun from low energy to high energy and produce X-rays by hitting the target. During the operation of the irradiation accelerator, the temperature of the accelerating tube will continue to rise due to the current on the surface of the accelerating tube wall and the bombardment of the electron beam. If the heat cannot be dissipated in time and effectively, the temperature inside the accelerating tube will be too high, thereby affecting the electron acceleration process inside, reducing the performance of the accelerating tube, and even damaging the accelerating tube.

[0003] However, the cooling effect of the accelerating tube water cooling structure in the related art is poor. Summary of the invention

[0012] In one embodiment, the cooling water channel assembly includes a plurality of connectors, and the connectors are detachably connected to the partition and the accelerating tube, respectively, so that the partition can be detachably arranged on the outer peripheral side of the accelerating tube.

[0034] In the related art, the water cooling structure of the accelerating tube 10 cools down the accelerating tube 10 by brazing a cooling water channel assembly 20 on the accelerating tube 10. However, brazing on the prepared accelerating tube will cause the cavity of the accelerating tube 10 to deform. The deformation of the cavity of the accelerating tube 10 will change the electric field distribution and electron motion trajectory inside it, thereby causing the acceleration performance of the accelerating tube 10 to deteriorate and fail to meet the acceleration requirements of high precision and high efficiency.

[0035] An embodiment of the present application provides a water cooling structure for an accelerating tube 10. Figure 1 , Figure 2 and Figure 6 The water cooling structure of the accelerating tube 10 includes an accelerating tube 10 and a cooling water channel assembly 20 .

[0036] The cooling water channel assembly 20 includes a plurality of partitions 21 , and the partitions 21 are detachably disposed around the circumference of the accelerating tube 10 .

[0037] The partitions 21 are arranged at intervals along the extending direction of the accelerating tube 10 , and the spaces between adjacent partitions 21 are connected to form a water flow channel 20 a extending along the extending direction of the accelerating tube 10 .

[0038] Another embodiment of the present application provides a cooling water channel assembly, and the cooling water channel assembly 20 is the cooling water channel assembly 20 of any embodiment of the present application.

[0039] Specifically, the cooling water channel assembly 20 refers to a component for cooling the accelerating tube 10. The cooling water channel assembly 20 removes the heat generated by the accelerating tube 10 through water circulation to maintain the operating temperature of the accelerating tube 10 within a reasonable range.

[0040] The partition plate 21 refers to a member constituting a boundary of the water flow channel 20a.

[0041] The structure type of the partition 21 is not limited. For example, the partition 21 is an arc-shaped or annular sheet structure, and its curvature matches the curvature of the outer circumference of the accelerating tube 10, ensuring that the partition 21 fits tightly with the outer wall of the accelerating tube 10 so that the cooling water moves along the water flow channel 20a.

[0042] The material type of the partition 21 is not limited. For example, the material type of the partition 21 is copper. Since copper is relatively soft, the flow path of the water flow channel 20a can be adaptively adjusted by adjusting the partition 21.

[0043] The connection method between the partition plate 21 and the accelerating tube 10 is not limited.

[0044] For example, the partition plate 21 and the accelerating tube 10 are connected by snapping.

[0045] For another example, the partition plate 21 is connected to the accelerating tube 10 by bolts.

[0046] Along the extending direction of the accelerating tube 10 , the distances between two adjacent partitions 21 may be the same or different.

[0047] The spacing range between adjacent partitions 21 is not limited, as long as a spacing space can be formed and each spacing space is connected to form a water flow channel 20a.

[0048] By using a plurality of partitions 21 to connect with the accelerating tube 10 , it is possible to facilitate the assembly of the partitions 21 and the accelerating tube 10 , thereby facilitating the formation of the water flow channel 20 a .

[0049] The shape of the water flow channel 20a is not limited.

[0050] For example, the water flow channel 20 a is an annular water flow channel 20 a arranged around the circumference of the accelerating tube 10 .

[0051] For another example, the water flow channel is a spiral water flow channel 20a. Thus, the spiral water flow channel 20a can increase the contact area and contact time between water and the accelerating tube 10, further improve the heat exchange efficiency, and further improve the cooling effect.

[0052] The water cooling structure of the accelerating tube 10 of the embodiment of the present application includes the accelerating tube 10 and the cooling water channel assembly 20. The cooling water channel assembly 20 includes a plurality of baffles 21, which are detachably arranged around the circumference of the accelerating tube 10. The baffles 21 are arranged at intervals along the extension direction of the accelerating tube 10, and the interval spaces between the adjacent baffles 21 are connected to form a water flow channel 20a extending along the extension direction of the accelerating tube 10. Therefore, on the one hand, the baffles 21 are detachably arranged around the accelerating tube 10, which avoids the deformation of the cavity of the accelerating tube 10 caused by the welding of the baffles 21 and the accelerating tube 10, and effectively protects the original structure and performance of the accelerating tube 10. On the other hand, the baffles 21 are arranged at intervals to form the water flow channel 20a arranged along the extension direction of the accelerating tube 10, which can effectively take away the heat generated by the accelerating tube 10 during operation, improve the cooling effect, and enable the accelerating tube 10 to maintain constant temperature operation, thereby improving the acceleration efficiency and accuracy of the accelerating tube 10.

[0053] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 6 , the partition 21 includes a first connecting section 211 and a second connecting section 212. Along the extension direction of the water flow channel 20a, the first connecting section 211 is located upstream of the second connecting section 212, and one end of the first connecting section 211 is connected to the second connecting section 212, and the other end of the first connecting section 211 is connected to the second connecting section 212 of the adjacent partition 21, so that the water flow channel 20a is arranged around the circumference of the outer surface of the accelerating tube 10. In this way, the water flow channel 20a can be arranged around the circumference of the outer surface of the accelerating tube 10, and the circumferentially surrounding water flow can more evenly absorb the heat generated at various positions on the surface of the accelerating tube 10, avoiding the occurrence of local overheating, thereby effectively improving the cooling uniformity and efficiency of the accelerating tube 10 as a whole.

[0054] Specifically, the first connecting segment 211 and the second connecting segment 212 may be integrally formed; or they may be separately formed, and the partition 21 is formed by connecting one end of the first connecting segment 211 with one end of the second connecting segment 212 .

[0055] Along the extension direction of the water flow channel 20a, the first connecting section 211 is located upstream of the second connecting section 212, which means that the cooling water passes through the first connecting section 211 and the second connecting section 212 of the partition plate 21 in sequence along the water flow channel 20a.

[0056] Along the water flow channel 20a, the second connecting section 212 of the upstream partition 21 is connected to the first connecting section 211 of the downstream partition 21.

[0057] The connection method of the first connection section 211 and the second connection section 212 of two adjacent partitions 21 is not limited, for example, welding or bolt connection.

[0058] It can be understood that the first connecting section 211 has a first opening, the second connecting section 212 has a second opening, and the fastener passes through the first opening and the second opening to achieve the connection between two adjacent partitions 21 .

[0059] One end of the first connecting section 211 is connected to the second connecting section 212 of the baffle 21 to which it belongs, forming a local connection structure inside the baffle 21; and the other end is connected to the second connecting section 212 of the adjacent baffle 21. Through such a connection method, multiple baffles 21 are connected end to end in sequence, so that the water flow channel 20a can be arranged around the outer surface of the accelerating tube 10.

[0060] In one embodiment, please refer to Figure 1 and Figure 3 The cooling water channel assembly includes a plurality of connectors 22, which are detachably connected to the partition 21 and the accelerating tube 10, respectively, so that the partition 21 can be detachably arranged on the outer peripheral side of the accelerating tube 10. Thus, on the one hand, it can be avoided that the partition 21 is welded to the accelerating tube 10, which causes the cavity of the accelerating tube 10 to deform, thereby affecting the performance of the accelerating tube 10. On the other hand, when the cooling water channel assembly 20 fails, the partition 21 can be quickly and conveniently removed from the accelerating tube 10 for repair or replacement. There is no need to disassemble the entire accelerating tube 10 water cooling system on a large scale, which greatly shortens the maintenance time, reduces the maintenance cost, and improves the overall availability and operation efficiency of the equipment.

[0061] Specifically, the connecting member 22 refers to a member for stably fixing the partition plate 21 to the outer peripheral side of the accelerating tube 10 .

[0062] The connection method between the connecting member 22 and the partition plate 21 is not limited.

[0063] For example, the connecting member 22 is snap-connected to the partition 21 .

[0064] For another example, the connecting member 22 is connected to the partition plate 21 by bolts.

[0065] The connection method between the connecting member 22 and the accelerating tube 10 is not limited.

[0066] For example, the connecting piece 22 is snap-connected to the accelerating tube 10 .

[0067] For another example, the connecting member 22 is connected to the accelerating tube 10 by bolts.

[0068] In a specific embodiment, the connecting member 22 is connected to the partition 21 with bolts. The connecting member 22 and the partition 21 have bolt holes. Bolts pass through the bolt holes to connect the connecting member 22 and the partition 21. The number of the connecting members 22 corresponds to the number of the bolt holes.

[0069] In a specific embodiment, the connecting member 22 is connected to the accelerating tube 10 with bolts. The connecting member 22 and the accelerating tube 10 have bolt holes. Bolts pass through the bolt holes to connect the connecting member 22 and the accelerating tube 10. The number of connecting members 22 corresponds to the number of bolt holes.

[0070] In a specific embodiment, the connecting member 22 is bolted to the accelerating tube 10, the connecting member 22 has a bolt hole, the accelerating tube 10 has a threaded hole, the bolt passes through the bolt hole and is connected to the threaded hole to connect the connecting member 22 to the accelerating tube 10, and the number of the connecting members 22 corresponds to the number of the bolt holes and the threaded holes.

[0071] In a specific embodiment, please refer to Figure 5 and Figure 6 The accelerating tube 10 includes an accelerating section 11, and a plurality of accelerating sections 11 are arranged at intervals along the extending direction of the water flow channel 20a to form the accelerating tube 10. The accelerating section 11 has a screw hole 11a, and the connecting piece 22 is connected to the screw hole 11a so that the partition 21 is fixed on the accelerating tube 10. Therefore, by providing the screw hole 11a on the accelerating section 11, the microwave performance of the accelerating cavity will not be affected when the partition 21 is installed on the accelerating section 11, and no readjustment is required after the partition 21 is installed.

[0072] In one embodiment, please refer to Figure 1 and Figure 3 The connecting member 22 includes a first panel 221 and a second panel 222 connected to each other. The first panel 221 is firmly connected to the accelerating tube 10, and the second panel 222 is firmly connected to the ends of two adjacent partitions 21 that are close to each other. Thus, the partitions 21 and the accelerating tube 10 can be stably connected.

[0073] Specifically, the first panel 221 refers to a portion of the connecting member 22 that directly contacts and establishes a fastened connection with the accelerating tube 10 .

[0074] The second panel 222 refers to a component that is fastened to two adjacent partitions 21 , so that the partitions 21 can be arranged in order on the periphery of the accelerating tube 10 according to a predetermined design and form a complete water flow channel 20 a .

[0075] The first panel 221 and the second panel 222 may be integrally formed, or may be separately formed and connected to each other to form the connecting member 22 .

[0076] The shape of the first panel 221 is not limited.

[0077] For example, the first panel 221 is a planar structure.

[0078] For another example, the first panel 221 is a curved structure.

[0079] The shape of the second panel 222 is not limited.

[0080] For example, the second panel 222 is a planar structure.

[0081] For another example, the second panel 222 is a curved structure.

[0082] The relative positions of the first panel 221 and the second panel 222 are not limited.

[0083] For example, the first panel and the second panel 222 are arranged vertically. Thus, the connection member 22 can be fixed more firmly on the periphery of the accelerating tube 10, reducing the risk of loosening or deformation of the connection member 22 due to uneven force, thereby ensuring the stability of the overall structure of the cooling water channel assembly 20.

[0084] In one embodiment, please refer to Figure 4 and Figure 6 The cooling water channel assembly includes at least one coupler 23. The coupler 23 is provided at at least one end of the accelerating tube 10. The coupler 23 has a plurality of water outlet channels 23a extending along the extending direction of the accelerating tube 10. The water outlet channels 23a are arranged at intervals along the circumference of the coupler 23 and are all connected to the water flow channel 20a. Therefore, by providing a plurality of water outlet channels 23a arranged at intervals along the circumference of the coupler 23, the cooling water can flow into the water flow channel 20a uniformly from all around the end of the accelerating tube 10, thereby effectively cooling the accelerating tube 10, avoiding the occurrence of local overheating, and improving the heat dissipation efficiency of the accelerating tube 10.

[0085] Specifically, the coupler 23 refers to a component that connects the accelerating tube 10 and the external waterway. External cooling water enters the water flow channel 20a through the water outlet channel 23a of the coupler 23.

[0086] The coupler 23 may be disposed at only one end of the accelerating tube 10 , or may be disposed at both opposite ends of the accelerating tube 10 .

[0087] The water outlet channel 23a of the coupler 23 is not limited.

[0088] For example, the coupler 23 has two water outlet channels 23 a.

[0089] For another example, the coupler 23 has three water outlet channels 23a.

[0090] The water outlet channels 23 a are arranged at intervals along the circumference of the coupler 23 . The distances between adjacent water outlet channels 23 a along the circumference of the coupler 23 may be the same or different.

[0091] In a specific embodiment, the accelerating tube 10 has an inlet end and an outlet end, and a coupler 23 is provided at both the inlet end and the outlet end. Cooling water flows into the water flow channel 20a from multiple water outlet channels 23a of the inlet end coupler 23. The water paths of the multiple water outlet channels 23a merge into one in the water flow channel 20a, and the accelerating tube 10 is circumferentially cooled when flowing along the water flow channel 20a. After the cooling water flows to the outlet end coupler 23, it is divided into multiple water flows and flows out through the water outlet channel 23a. In view of the presence of other structural accessories at both ends of the accelerating tube 10, the end plates cannot be placed at both ends of the accelerating tube 10 to construct a spiral waterway. Therefore, water outlet channels 23a are provided at both ends of the accelerating tube 10 and are spaced apart along the circumference of the coupler 23, so as to achieve circumferential cooling treatment of both ends of the accelerating tube 10, thereby effectively improving the cooling effect of both ends of the accelerating tube 10.

[0092] In one embodiment, please refer to Figure 4 The coupler 23 has a waveguide installation position on one side along the first direction, and a water flow channel 20a on the other side along the first direction; along the second direction, a water flow channel 20a is respectively provided on the opposite sides of the connector 22, and the first direction and the second direction are perpendicular. Thus, the cooling water can avoid the waveguide structure, effectively avoiding the cooling water directly contacting the waveguide during the flow process or the electromagnetic interference, physical impact and other adverse effects on the waveguide caused by factors such as water flow fluctuations and splashing.

[0093] Specifically, the waveguide installation position refers to a position for installing the waveguide. The waveguide is arranged in the waveguide installation position and communicates with the accelerating tube 10, thereby being able to transfer high-frequency microwave energy into the accelerating tube 10.

[0094] In a specific embodiment, please refer to Figure 1 The water cooling structure of the accelerating tube 10 includes a water jacket 30 and a flange. The water jacket 30 is sleeved on the outer peripheral side of the accelerating tube 10. At least one end of the water jacket 30 is provided with a flange, which is used to seal the water jacket 30. The coupler 23 has a plurality of water outlet channels 23a, and the water outlet channels 23a are parallel. On the one hand, the plurality of water outlet channels 23a will not hinder the installation of the water jacket 30, and on the other hand, the water cooling effect of both ends of the accelerating tube 10 can be excellent.
