[0031] The following will be described in combination with Figures 1 to 6 The structure and working process of the directional cooling device for the high heat load area of the ion accelerator of the present application are described.

[0032] One embodiment of the present application provides a directional cooling device for the high heat load area of an ion accelerator, which comprises Figure 1 and Figure 2 As shown in the figure, the directional cooling device for the high heat load area of the ion accelerator comprises a fixed pipe 1, a connecting pipe 2 and a cooling pipe 3. The fixed pipe 1 is fixedly connected to the outlet end of the vacuum pipe of the ion accelerator. The connecting pipe 2 is detachably connected to the fixed pipe 1. The cooling pipe 3 is sleeved on the outer peripheral surface of the connecting pipe 2 in a spiral structure. A cooling medium flows in the cooling pipe 3, which is used to cool the connecting pipe 2. The cooling pipe 3 comprises a first spiral section 31 close to the fixed pipe 1 and a second spiral section 32 away from the fixed pipe 1. The first spiral section 31 and the second spiral section 32 are communicated. The pitch of the first spiral section 31 is smaller than the pitch of the second spiral section 32.

[0033] The directional cooling device for high heat load area of ion accelerator of the embodiment can be used for directional cooling of the high heat load area of the ion accelerator, wherein the fixed pipe 1 is fixed at the outlet end of the ion accelerator vacuum pipe as a permanent interface through welding or flange connection to ensure vacuum tightness; the connecting pipe 2 is connected to the fixed pipe 1 through quick-release connection structure to allow replacement of the cooling unit without damaging the vacuum environment; the cooling pipe 3 is wound on the outer circumferential surface of the connecting pipe 2, and when the high-temperature beam and ion flow pass through the connecting pipe 2, the cooling medium (generally cooling water) in the cooling pipe 3 wrapped on the outer circumferential surface of the connecting pipe 2 cools and lowers the temperature of the connecting pipe 2 and the high-temperature ion flow in the connecting pipe 2; the cooling pipe 3 adopts variable pitch design, the first spiral section 31 is used as the proximal end with dense pitch, and the second spiral section 32 is used as the distal end with loose pitch; and the cooling medium of the cooling pipe 3 flows through the first spiral section 31 and then the second spiral section 32 under forced convection.

[0034] It can be understood that after the fixed pipe 1 is communicated with the connecting pipe 2, the high-temperature ions enter the fixed pipe 1 through the outlet pipe of the ion accelerator injection device, and then flow into the connecting pipe 2, and the cooling pipe 3 on the outer circumferential surface of the connecting pipe 2 cools the high-temperature ions. When the accelerated ions pass through the connecting pipe 2, they first pass through the first spiral section 31 of the cooling pipe 3 with dense number of turns. The first spiral section 31 of the cooling pipe 3 of the embodiment is arranged in a dense spiral manner in the region, and the pitch is small, so that when the cooling medium flows through this region, a flow path with multiple turns is formed. The first spiral section 31 is located in the proximal end high-temperature region of the ion beam, significantly increases the residence time of the cooling medium in the high-temperature region, maximizes the contact area of the cooling medium with the connecting pipe 2 wall, and prolongs the heat exchange time through the multiple-turn flow path, so that the heat generated by the high-temperature ion beam can be fully absorbed. The dense spiral structure realizes the maximum heat exchange area in a limited space, and is particularly suitable for the initial cooling stage of the high-temperature ion beam after acceleration.

[0035] The ion beam cooled by the first spiral section 31 of the cooling pipe 3 continues to flow in the connecting pipe 2 and reaches the second spiral section 32 of the cooling pipe 3. The second spiral section 32 of the cooling pipe 3 is arranged in a relatively loose spiral manner in the region. On the one hand, the appropriately widened pitch effectively reduces the flow resistance of the cooling medium, avoiding the pressure accumulation of the cooling medium caused by the first spiral section 31. On the other hand, the second spiral section 32 balances the pressure distribution of the entire cooling system, ensures that the cooling medium can flow out smoothly, and prevents flow instability caused by uneven pressure. At the same time, although the heat exchange efficiency of the second spiral section 32 is relatively low, the temperature of the ion beam has been significantly reduced after passing through the first spiral section 31. This staged design not only ensures the cooling effect, but also maintains the fluid performance of the system.

[0036] In some embodiments of the directional cooling device for high heat load area of ion accelerator of the present application, further referring to Figure 1As shown, the directional cooling device for high heat load area of ion accelerator further comprises a cooling box 4, the connecting pipe 2 is arranged through the cooling box 4, the cooling pipe 3 is arranged in the cooling box 4, the upper surface of the cooling box 4 is provided with an inlet pipe 41, the inlet pipe 41 is communicated with the first spiral section 31, the lower surface of the cooling box 4 is provided with an outlet pipe 42, and the outlet pipe 42 is communicated with the second spiral section 32.

[0037] It can be understood that the high-temperature ions enter the fixed pipe 1 through the outlet pipe of the ion accelerator injection device, and then flow into the connecting pipe 2, when entering the cooling box 4, the cooling medium enters the cooling box 4 from the inlet pipe 41, flows through the first spiral section 31 (enhances heat dissipation in the high-temperature area) and the second spiral section 32 (reduces flow resistance) of the cooling pipe 3, and finally is discharged from the outlet pipe 42, so that the partitioned rapid cooling treatment of the ions is finally realized. The cooling box 4 serves as a storage and circulation container for the cooling medium, the cooling medium flows and circulates through the inlet pipe 41 and the outlet pipe 42, the upper surface of the cooling box 4 is fixedly communicated with the inlet pipe 41, the lower surface of the cooling box 4 is fixedly communicated with the outlet pipe 42, the inlet and outlet of the cooling medium are distributed on the upper and lower surfaces to form a clear flow direction, avoid the formation of a dead zone in the cooling box 4, and form a closed loop, so that the cooling efficiency is stable.

[0038] The cooling box 4 is equivalent to an external cooling component, the connecting pipe 2 is communicated with the fixed pipe 1, the connecting pipe 2 penetrates through the cooling box 4, in some specific examples, the cooling box 4 comprises two half box bodies which are fixedly spliced, the two half box bodies are fixedly spliced by the threaded column 43, so that the cooling component can be quickly assembled and fixed. The temperature sensor 44 is fixedly arranged on the upper surface of the cooling box 4, the temperature probe of the temperature sensor 44 is closely attached to the outer circumferential surface of the connecting pipe 2, the temperature of the outer side of the beam pipe after being cooled by the connecting pipe 2 and the cooling pipe 3 can be monitored by the temperature sensor 44, so that the cooling efficiency is ensured.

[0040] The fixed pipe 1 and the connecting pipe 2 of the directional cooling device for high heat load area of ion accelerator in the embodiment adopt the combination of the clamping type quick release mechanism, so that the cooling efficiency and the maintenance convenience of the cooling device of the ion accelerator are significantly improved. In the use process, the original pipe of the accelerator does not need to be changed, the fixed pipe 1 is retained on the vacuum pipe as a permanent interface, and subsequently only the connecting pipe 2 and the cooling box 4 module need to be connected / disconnected through the clamping type quick release mechanism.

[0041] It can be understood that the embodiment is provided with the insertion tube 21 at the end of the connecting pipe 2, which is used for insertion with the fixed pipe 1. When the insertion tube 21 is inserted into the fixed pipe 1, the sliding sleeve 5 is slid to the position of the insertion slot 22 on the outer periphery of the insertion tube 21, the sliding column 51 is inserted into the insertion slot 22, the sliding sleeve 5 is connected with the insertion tube 21, and then the fixed pipe 1 is connected and fixed with the connecting pipe 2. When disassembling, the sliding column 51 is pulled out of the insertion slot 22, the sliding sleeve 5 is disconnected with the insertion tube 21, and the fixed pipe 1 is disconnected with the connecting pipe 2.

[0042] In some specific examples, referring to Figure 4 It is shown that the sliding column 51 is provided with the limiting plate 52 at the part outside the sliding sleeve 5, the sliding column 51 is provided with the mounting plate 53 and the reset spring 54 at the part inside the sliding sleeve 5, one end of the reset spring 54 is connected to the inner wall of the sliding sleeve 5, the other end is connected to the mounting plate 53, and the insertion block 55 is mounted on the side of the mounting plate 53 away from the reset spring 54.

[0043] In combination with Figure 3 and Figure 4 It is shown that one end of the sliding column 51 extends into the sliding sleeve 5 and is fixedly connected with the mounting plate 53, the lower surface of the mounting plate 53 is fixedly mounted with the insertion block 55, the outer surface of the sliding column 51 is provided with the reset spring 54, the two ends of the reset spring 54 are connected with the mounting plate 53 and the inner side wall of the sliding sleeve 5 respectively, the reset force of the insertion block 55 is provided, the insertion block 55 is used for insertion into the insertion slot 22 and is provided with sliding, the width of the insertion block 55 is the same as the width of the insertion slot 22, so that the insertion block 55 can be completely inserted into the inside of the insertion slot 22, the part of the sliding column 51 not extending into the sliding sleeve 5 is fixedly mounted with the limiting plate 52, the limiting plate 52 can facilitate the limiting treatment of the sliding column 51 and reduce the possibility of falling off. When mounting, the insertion tube 21 is inserted into the fixed pipe 1, the sliding sleeve 5 is slid to the farthest sliding position, at this time, the sliding column 51 of the sliding sleeve 5 is aligned with the insertion slot 22, the sliding column 51 is driven to move towards the insertion slot 22, the insertion block 55 is inserted into the insertion slot 22, and then the quick mounting of the insertion tube 21 with the fixed pipe 1 is realized.

[0044] Further, referring to Figure 5 It is shown that the outer periphery of the insertion tube 21 is provided with the annular groove 23 at the part beside the insertion slot 22, and the side groove wall of the annular groove 23 forms the inclined groove wall 24. The insertion block 55 is provided with the inclined surface 57 consistent with the inclination of the inclined groove wall 24, and the end of the sliding column 51 outside the sliding sleeve 5 is provided with the pull ring 56.

[0045] It can be understood that the outer circumferential surface of the insertion tube 21 is provided with an annular groove 23, the side wall of the annular groove 23 is provided as a beveled groove wall 24, the cross-sectional area of the insertion block 55 is triangular, the side wall of the insertion block 55 is provided with a bevel 57 consistent with the slope of the beveled groove wall 24, and in the initial state, the insertion block 55 at the lower end of the sliding column 51 extends into the annular groove 23 and the bevel 57 of the insertion block 55 is in contact with the beveled groove wall 24 of the annular groove 23, and the contact surfaces form a wedge-shaped structure. During the sliding process of the sliding sleeve 5, the beveled groove wall 24 of the annular groove 23 continuously presses the bevel 57 of the insertion block 55, and the insertion block 55 is pushed out of the annular groove 23, when the insertion block 55 at the lower end of the sliding column 51 moves to the insertion slot 22, at this time, the insertion block 55 is driven to move back by the elastic force of the return spring 54, so that the insertion block 55 is inserted into the insertion slot 22, when the insertion block 55 is inserted into the insertion slot 22, the vertical part of the insertion block 55 is in contact with the inner wall of the insertion slot 22, and the insertion block 55 is locked and fixed, thereby realizing the quick fixing of the insertion tube 21. When it is necessary to disconnect the connection between the insertion tube 21 and the fixed tube 1, the pull ring 56 provided at the end of the sliding column 51 outside the sliding sleeve 5 is pulled to move the sliding column 51 away from the insertion slot 22, so that the insertion block 55 is separated from the insertion slot 22, and the quick disconnection of the insertion tube 21 and the fixed tube 1 is realized.

[0046] In some embodiments of the directional cooling device for the high heat load area of the ion accelerator, the combination of Figure 3 and Figure 6 It can be understood that the outer circumferential surface of the insertion tube 21 is provided with an annular groove 23, the side wall of the annular groove 23 is provided as a beveled groove wall 24, the cross-sectional area of the insertion block 55 is triangular, the side wall of the insertion block 55 is provided with a bevel 57 consistent with the slope of the beveled groove wall 24, and in the initial state, the insertion block 55 at the lower end of the sliding column 51 extends into the annular groove 23 and the bevel 57 of the insertion block 55 is in contact with the beveled groove wall 24 of the annular groove 23, and the contact surfaces form a wedge-shaped structure. During the sliding process of the sliding sleeve 5, the beveled groove wall 24 of the annular groove 23 continuously presses the bevel 57 of the insertion block 55, and the insertion block 55 is pushed out of the annular groove 23, when the insertion block 55 at the lower end of the sliding column 51 moves to the insertion slot 22, at this time, the insertion block 55 is driven to move back by the elastic force of the return spring 54, so that the insertion block 55 is inserted into the insertion slot 22, when the insertion block 55 is inserted into the insertion slot 22, the vertical part of the insertion block 55 is in contact with the inner wall of the insertion slot 22, and the insertion block 55 is locked and fixed, thereby realizing the quick fixing of the insertion tube 21. When it is necessary to disconnect the connection between the insertion tube 21 and the fixed tube 1, the pull ring 56 provided at the end of the sliding column 51 outside the sliding sleeve 5 is pulled to move the sliding column 51 away from the insertion slot 22, so that the insertion block 55 is separated from the insertion slot 22, and the quick disconnection of the insertion tube 21 and the fixed tube 1 is realized.

[0047] It can be understood that the outer circumferential surface of the insertion tube 21 is provided with an annular groove 23, the side wall of the annular groove 23 is provided as a beveled groove wall 24, the cross-sectional area of the insertion block 55 is triangular, the side wall of the insertion block 55 is provided with a bevel 57 consistent with the slope of the beveled groove wall 24, and in the initial state, the insertion block 55 at the lower end of the sliding column 51 extends into the annular groove 23 and the bevel 57 of the insertion block 55 is in contact with the beveled groove wall 24 of the annular groove 23, and the contact surfaces form a wedge-shaped structure. During the sliding process of the sliding sleeve 5, the beveled groove wall 24 of the annular groove 23 continuously presses the bevel 57 of the insertion block 55, and the insertion block 55 is pushed out of the annular groove 23, when the insertion block 55 at the lower end of the sliding column 51 moves to the insertion slot 22, at this time, the insertion block 55 is driven to move back by the elastic force of the return spring 54, so that the insertion block 55 is inserted into the insertion slot 22, when the insertion block 55 is inserted into the insertion slot 22, the vertical part of the insertion block 55 is in contact with the inner wall of the insertion slot 22, and the insertion block 55 is locked and fixed, thereby realizing the quick fixing of the insertion tube 21. When it is necessary to disconnect the connection between the insertion tube 21 and the fixed tube 1, the pull ring 56 provided at the end of the sliding column 51 outside the sliding sleeve 5 is pulled to move the sliding column 51 away from the insertion slot 22, so that the insertion block 55 is separated from the insertion slot 22, and the quick disconnection of the insertion tube 21 and the fixed tube 1 is realized.

[0048] Specifically, when installing the directional cooling device of the ion accelerator high heat load area of the embodiment, after pressing the clamping column 27 to press it into the installation slot 25, the insertion tube 21 is inserted into the fixed tube 1, and the fixed tube 1 is provided with a through hole 11 matched with the clamping column 27. When the clamping column 27 slides to the through hole 11, the clamping column 27 is subjected to the elastic force of the compression spring 26, and the clamping column 27 penetrates the through hole 11. At the same time, during the insertion of the insertion tube 21, the insertion block 55 is always in contact with the outer surface of the insertion tube 21. When the insertion block 55 slides to the annular groove 23, it is subjected to the elastic force of the reset spring 54 and extends into the annular groove 23. When the insertion tube 21 and the sliding sleeve 5 continue to move relative to each other until the clamping column 27 penetrates the through hole 11, the insertion block 55 is located at the insertion slot 22 at this time, and the insertion block 55 is inserted into the insertion slot 22 under the elastic force of the reset spring 54. When the insertion block 55 is inserted into the insertion slot 22, the insertion tube 21 is pulled outwards at this time, and the vertical part of the insertion block 55 is in contact with the inner wall of the insertion slot 22. Moreover, the clamping column 27 and the through hole 11 are axially locked, so that the insertion tube 21 (connecting tube 2) and the fixed tube 1 form a double connection and fixation.

[0049] In some embodiments of the directional cooling device of the ion accelerator high heat load area of the present application, referring again to Figure 3 As shown, the outer peripheral surface of the fixed tube 1 is fixedly sleeved with a mounting ring 12, and the end surface of the mounting ring 12 towards the connecting tube 2 is uniformly provided with a plurality of sliding rods 13. The sliding rods 13 are provided on the sleeve wall of the sliding sleeve 5 and form a sliding fit with the sliding sleeve 5. The sliding rods 13 are sleeved with tension springs 14, one end of the tension springs 14 is connected with the mounting ring 12, and the other end is connected with the sliding sleeve 5. Further, the clamping column 27 is provided with a spherical protrusion 28 towards the end of the fixed tube 1. The sliding sleeve 5 slides on the outer peripheral surface of the fixed tube 1, and the inner wall surface of the sliding sleeve 5 is adapted to form a touch pressure with the spherical protrusion 28.

[0050] It can be understood that when it is necessary to quickly disassemble the connecting tube 2, the sliding column 51 is pulled outwards, the insertion block 55 is pulled outwards to separate from the insertion slot 22, and the locking and fixation of the insertion slot 22 is released. At this time, the sliding sleeve 5 is pulled, and the sliding sleeve 5 drives the sliding column 51 and the insertion block 55 to slide towards the mounting ring 12. At the same time, in the sliding process, the sliding sleeve 5 will extrude the spherical protrusion 28 on the upper side of the clamping column 27, so as to extrude the clamping column 27 into the installation slot 25, and the locking and fixation of the insertion tube 21 is released. At this time, the connecting tube 2 can be directly pulled out to quickly disassemble and separate the connecting tube 2 and the fixed tube 1. After the circulating pipe connected with the liquid inlet pipe 41 and the liquid outlet pipe 42 is disconnected, the cooling box 4 can be directly pulled out for quick disassembly and maintenance.

[0051] In some embodiments of the directional cooling device for the high heat load area of the ion accelerator, the insertion tube 21 is provided with a sealing sleeve 29 at the end of the fixed tube 1, which is generally made of butyronitrile material, and can realize the sealing of the insertion tube 21 after insertion into the fixed tube 1 when the fixed tube 1 is connected with the connecting tube 2.

[0052] Based on the structure of the directional cooling device for the high heat load area of the ion accelerator in each of the above embodiments or examples, the present application provides a cooling device which can be directed to the high heat load area of the ion accelerator. Through the design of the variable pitch spiral cooling tube 3, the first spiral section 31 enhances the heat dissipation at high temperature, and the second spiral section 32 reduces the flow resistance. In combination with the clamping type quick release mechanism, the cooling efficiency and maintenance convenience of the cooling device of the ion accelerator are significantly improved. The directional reinforced cooling can be realized for the high heat load area such as the front-end tube of the analysis magnet and the outlet of the acceleration tube, so as to avoid the thermal distortion of the beam. At the same time, through the modular buckle, the insertion block-slot linkage and spring reset, the cooling device can be quickly disassembled, and during the installation and disassembly process, no screwdriver or other disassembly tools are needed, so that the maintenance time is greatly shortened, and the disassembly and maintenance efficiency of the device is improved.
