Description

Technical Field

[0001] This utility model relates to the field of particle accelerator technology, and in particular to a modular particle accelerator coil / magnet power supply chassis. Background Technology

[0002] Accelerator power supplies are crucial components in particle accelerators, characterized by high power, high current, and high current accuracy and stability. Due to the diverse operating modes, internal structures, and heat dissipation methods of accelerator power supplies, most are non-standard devices, custom-developed and assembled using different functional components as needed, making debugging difficult. Furthermore, the lack of unified standards results in poor versatility, a mixed technical system, and complex structural and process control.

[0003] Furthermore, integrated power supply designs are typically compact, resulting in high power density and concentrated heat generation, making heat dissipation a significant challenge. Inadequate heat dissipation design can lead to excessively high temperatures within the chassis, affecting power supply performance and lifespan, and even causing malfunctions. Additionally, assembly processes often face space constraints, resulting in limited operating space and significantly increased operational difficulty. Later maintenance and upgrades may require the disassembly of multiple components, leading to increased maintenance costs. Utility Model Content

[0004] To address the technical problems existing in the prior art, the purpose of this utility model is to provide a modular particle accelerator coil / magnet power supply chassis, which solves the structural problems of existing non-standard integrated power supplies.

[0005] The objective of this utility model is achieved through the following technical solution: a modular particle accelerator coil / magnet power supply chassis, including a chassis body and its built-in first backplate and second backplate. The first backplate and the second backplate are arranged facing each other, dividing the chassis cavity into a first compartment, a second compartment, and a third compartment in sequence. The first compartment is used to place board-type control modules, the third compartment is used to place board-type functional modules, and the second compartment is a wiring and operation space for interconnecting the modules. The second backplate facing the second compartment has a plurality of quick-connect terminals on its surface, which are used to independently connect each functional module to the second backplate. The quick-connect terminals are interconnected through copper busbars.

[0006] Specifically, the chassis body includes a front panel, a rear panel, an upper panel, a lower panel, and two side panels. The front panel and the rear panel are each composed of multiple independent panels. Each independent panel includes a board panel that is vertically connected to a board-type circuit module placed inside the chassis cavity.

[0007] Furthermore, it also includes a crossbeam and a guide rail. The crossbeam and the guide rail are erected perpendicularly to each other to form a frame for fixing the board-type circuit module. By removing the corresponding board panel, the board-type circuit module can be pulled out or installed along the guide rail.

[0008] Specifically, the crossbeam includes a front crossbeam and a rear crossbeam. At least two front crossbeams are arranged vertically on the inner wall of the front panel, and each independent panel is connected to the front crossbeam by screws to achieve the assembly of the front panel. At least two rear crossbeams are arranged vertically on the inner wall of the rear panel, and each independent panel is connected to the rear crossbeam by screws to achieve the assembly of the rear panel.

[0009] Furthermore, the crossbeam also includes a first middle crossbeam and a second middle crossbeam, with at least two first middle crossbeams and at least two second middle crossbeams arranged vertically within the chassis cavity, and the first middle crossbeam and the second middle crossbeam are arranged parallel to the front crossbeam and the rear crossbeam; the first middle crossbeam is close to the front crossbeam, and the first back plate is arranged between the two upper and lower first middle crossbeams; the second middle crossbeam is close to the rear crossbeam, and the second back plate is arranged between the two upper and lower second middle crossbeams.

[0010] Specifically, the guide rail includes at least two first guide rails and at least two second guide rails. The first guide rails are disposed in the first compartment and are vertically erected between the front crossbeam and the first middle crossbeam to form several first frames for placing board-type control modules. The second guide rails are disposed in the third compartment and are vertically erected between the rear crossbeam and the second middle crossbeam to form several second frames for placing board-type functional modules.

[0011] Furthermore, the independent panel also includes a ventilation panel and a blind panel.

[0012] Specifically, the front panel has front flanges on both sides to reinforce the connection between the front panel and the two side end panels, and the front flanges have handles; the rear panel has rear flanges on both sides to reinforce the connection between the rear panel and the two side end panels.

[0013] Furthermore, the first back panel does not completely separate the first compartment and the second compartment, and the connecting part is provided with a slide rail for placing the power module; or, the second back panel does not completely separate the second compartment and the third compartment, and the connecting part is provided with a slide rail for placing the power module.

[0014] Furthermore, the upper panel, lower panel, and / or both side panels are provided with ventilation holes.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] 1. This utility model upgrades and remodels the power supply chassis, avoiding the messy situation inside the power supply chassis caused by the use of traditional wires, so that the chassis can be planned with reasonable ventilation channels and improve heat dissipation.

[0017] 2. In terms of layout, this utility model divides the wiring and operation space through the first and second back plates, providing ample space for convenient operation while also ensuring more rational and safer wiring. Furthermore, it separates the functional modules from the control modules; the front half of the chassis houses the control modules, while the rear half contains the functional modules. This design avoids electromagnetic interference from the high current and high voltage generated by the power modules within the functional modules, ensuring the stability and accuracy of the control circuit. Additionally, power load fluctuations and temperature rise during operation can affect circuit performance; separating the two improves the overall reliability of the system.

[0018] 3. The copper busbar used in this utility model has high mechanical strength and is not easy to break or deform. In some harsh working environments or places with mechanical vibration, the copper busbar can maintain better connection because of its regular shape and size. Also, because the copper busbar is a one-piece molded structure, the possibility of errors is reduced during installation and fixing. Furthermore, because of its large heat dissipation area, its heat dissipation performance is better than that of wires, and the heat generated during high current transmission can be dissipated more quickly, which can effectively avoid electrical failures caused by overheating.

[0019] 4. This utility model features a frame to accommodate the inserted circuit board-type modules, enabling rapid installation and removal of the modules and quick adjustment of the power supply structure. Furthermore, the power supply uses a sliding rail to calibrate the position of the power module, saving time and effort during installation and preventing the possibility of incorrect wiring.

[0036] To facilitate understanding of this utility model, the technical solutions and advantages of the utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Any mechanisms or methods not elaborated in this utility model can be referred to in the prior art. The specific structure and features of this utility model are illustrated below by way of example and should not constitute any limitation on this utility model. Furthermore, any technical feature mentioned below (including implicit or disclosed features), as well as any technical feature directly shown or implied in the figures, can be arbitrarily combined or deleted among these technical features to form more other embodiments that may not be directly or indirectly mentioned in this utility model. The accompanying drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0037] Example 1

[0038] like Figure 1-4As shown, the modular particle accelerator coil / magnet power supply chassis of Embodiment 1 includes a chassis body and a first backplate 41 and a second backplate 42 placed inside it. The first backplate 41 and the second backplate 42 are arranged facing each other, dividing the chassis cavity into a first compartment 51, a second compartment 52, and a third compartment 53. The first compartment 51 is used to house a board-type control module 600, the third compartment 53 is used to house a board-type functional module 700, and the second compartment 52 is the wiring operation space for interconnecting the modules. The second backplate 42 facing the second compartment 52 has several quick-connect terminals 45, which are used to independently connect each functional module to the second backplate 42. The quick-connect terminals 45 are interconnected through copper busbars 46. Thus, by adjusting the wiring on the second backplate 42, different circuits and different polarity power supply modes can be switched.

[0039] Specifically, the main body of the chassis is a square container with six end faces, namely the front panel 11, the rear panel 12, the upper panel 13, the lower panel 14, and the two side end panels 15, which together enclose and form the inner cavity of the chassis.

[0040] The front panel 11 is composed of multiple independent panels, which can be blind plates 21, circuit board panels 23, or ventilation panels 25. Blind plates 21 refer to enclosed panels, circuit board panels 23 refer to panels vertically connected to circuit board modules placed inside the chassis, and ventilation panels 25 refer to panels with ventilation holes 250. Preferably, in this embodiment, the front panel 11 horizontally comprises a blind plate 21, multiple circuit board panels 23, and a ventilation panel 25. The inner wall of the front panel 11 has two vertically arranged front crossbeams 31, located at the upper and lower edges of the front panel 11, respectively. Each independent panel of the front panel 11 is connected to the front crossbeams 31 with screws to fix and assemble the front panel 11. The corresponding independent panel can be removed by unscrewing the corresponding screws. Furthermore, front flanges 17 are provided on both sides of the front panel 11 to reinforce the connection between the front panel 11 and the side end panels 15. The front flanges 17 have handles 170 for easy carrying and movement.

[0041] The rear panel 12 is also composed of multiple independent panels. In this preferred embodiment, the rear panel 12 horizontally includes multiple card panels 23. The inner wall of the rear panel 12 has two rear crossbeams 32 arranged vertically, located at the upper and lower edges of the rear panel 12, respectively. Each independent panel of the rear panel 12 is connected to the rear crossbeams 32 by screws, thus fixing and assembling the rear panel 12. The corresponding independent panel can be removed by unscrewing the corresponding screws. Rear flanges 18 are provided on both sides of the rear panel 12 to reinforce the connection between the rear panel 12 and the side end panels 15.

[0042] The upper panel 13, the lower panel 14, and the two side panels 15 are each integrally formed, and the panels are fixedly connected to each other by screws.

[0043] The chassis also features a central crossbeam and guide rails. The guide rails are perpendicular to each crossbeam in pairs, forming a square frame for fixing the board-type circuit modules. The board-type circuit modules refer to the aforementioned control modules and functional modules, all of which are circuit modules placed inside the chassis cavity. The central crossbeam is divided into two first central crossbeams 34 and two second central crossbeams 35. The two first central crossbeams 34 and two second central crossbeams 35 are arranged vertically, and are parallel to the front crossbeam 31 and the rear crossbeam 32. The first central crossbeams 34 are closer to the front crossbeam 31, and the second central crossbeams 35 are closer to the rear crossbeam 32.

[0044] The first backplate 41 is positioned between the two upper and lower first middle crossbeams 34, and the second backplate 42 is positioned between the two upper and lower second middle crossbeams 35, with a certain distance between them. The first backplate 41 and the front panel 11 form the first compartment 51, and the first backplate 41 and the second backplate 42 form the second compartment 52. The second backplate 42 and the rear panel 12 form the third compartment 53. The first compartment 51 is used to house the board-type control module 600, the third compartment 53 is used to house the board-type function module 700, and the second compartment 52 provides operating space for adjusting wiring.

[0045] The guide rails are divided into at least two first guide rails 37 and at least two second guide rails 38. The first guide rails 37 are located in the first compartment 51 and are vertically erected between the front crossbeam 31 and the first middle crossbeam 34, forming several first frames. The first frames are used to house the board-type control module 600. The second guide rails 38 are located in the third compartment 53 and are vertically erected between the rear crossbeam 32 and the second middle crossbeam 35, forming several second frames. The second frames are used to house the board-type functional module 700.

[0046] The second back panel 42 facing the second compartment 52 is provided with several quick-connect terminals 45. The board-type functional modules 700 in the third compartment 53 are connected to the second back panel 42 through the quick-connect terminals 45. Each board-type functional module 700 is functionally independent. The quick-connect terminals 45 are fixed to the copper busbar 46 by screws to realize the connection relationship between each functional module and between the functional modules and other modules.

[0047] Furthermore, in this preferred embodiment, the first back plate 41 does not completely separate the first compartment 51 and the second compartment 52. The first compartment 51 and the second compartment 52 remain connected on one side next to the first back plate 41. This connected portion has a slide rail 48 on the lower panel 14 for placing the power module 800. The slide rail 48 is located next to the first back plate 41 and corresponds to an independent panel on the front panel 11, which is a ventilation plate 25. The slide rail 48 not only enables the plug-in installation of the power module 800 but also allows for calibration of the installation position of the power module 800. This saves time and effort during installation and avoids the possibility of incorrect wiring. The lower panel 14 also has a third back plate 43. The third back plate 43 is connected to the power module 800 through several quick-connect terminals 45. The third back plate 43 is connected to the second back plate 42 through a copper busbar 46, thereby enabling the connection between the power module 800 and the functional module.

[0048] When using the chassis of Embodiment 1, the board-type control module 600 is sequentially inserted into each of the first frames in the first compartment 51 and fixed. The board-type function module 700 is sequentially inserted into each of the second frames in the third compartment 53 and fixed. The power module 800 is installed on the slide rail 48. The copper busbar 46 is fixed to the quick-connect terminal 45 with screws to connect the various modules and form a specific circuit pattern. The wiring is mainly concentrated in the second compartment 52, which effectively avoids messy wiring and facilitates operation. Finally, the various end panels of the chassis body are fixed with screws to achieve closed installation of the chassis. If it is necessary to adjust the power mode and replace the module in the future, simply remove the corresponding independent panel, take out the corresponding board-type circuit module, replace it with the required module, and reseal the independent panel to achieve quick disassembly and assembly.

[0049] Example 2

[0050] like Figure 5-7 As shown, the modular particle accelerator coil / magnet power supply chassis of Embodiment 2 is basically the same as that of Embodiment 1. However, Embodiment 1 targets a power module 800 with a smaller size and power, while Embodiment 2 is suitable for power modules 800 with larger size and power. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0051] 1) In Embodiment 2, both the front panel 11 and the rear panel 12 are divided into upper and lower independent panels. Preferably, in Embodiment 2, the upper layer of the front panel 11 includes a blind plate 21, multiple board panels 23, and a ventilation plate 25, while the lower layer of the front panel 11 is a ventilation plate 25. The upper layer of the rear panel 12 consists of multiple board panels 23, and the lower layer of the rear panel 12 is a ventilation plate 25. This increases the overall height of the chassis, accommodating the installation of high-power, large-volume power modules 800.

[0052] 2) In Embodiment 2, there are three crossbeams: front crossbeam 31, rear crossbeam 32, first middle crossbeam 34, and second middle crossbeam 35. An additional crossbeam is placed at the connection between the upper and lower layers for reinforcement. The first back plate 41, second back plate 42, first frame, and second frame are all located in the upper area, so that the upper area is used to place the control module and functional modules, and the lower area is used to place the power module 800.

[0053] 3) The second back panel 42 does not completely separate the second compartment 52 and the third compartment 53. The second compartment 52 and the third compartment 53 are still connected in the lower area. This connected part has a slide rail 48 on the lower panel 14 for placing the power module 800. The slide rail 48 is located below the second back panel 42 and corresponds to the ventilation plate 25 of the rear panel 12 located in the lower layer. In embodiment 2, the third back panel 43 is not provided. The power module 800 is connected to the second back panel 42 through a copper busbar 46 or a cable, thereby realizing the connection between the power module 800 and the functional module.

[0054] 4) For the high-power power module 800, in addition to increasing the height of the chassis and expanding the internal space, the upper panel 13 is provided with ventilation holes 250 to further improve the heat dissipation effect.

[0055] In other embodiments, ventilation holes 250 can be provided on the lower end panel 14 and both side end panels 15 to improve heat dissipation.

[0056] Compared to existing technologies, this utility model's modular particle accelerator coil / magnet power supply chassis upgrades and transforms the power supply chassis, avoiding the messy internal layout caused by traditional wiring. This allows for a more rational ventilation system, improving heat dissipation. The first and second backplates define the wiring and operation space, providing ample room for convenient operation while ensuring more rational and safer wiring. Furthermore, the separation of functional and control modules—with the control module in the front and the functional modules in the rear—prevents electromagnetic interference from the high current and voltage generated by the power modules in the functional modules, ensuring the stability and accuracy of the control circuit. Additionally, power load fluctuations and temperature rise during operation can affect circuit performance; separating the two improves the overall system reliability.

[0057] The above embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of protection of the present utility model. For those skilled in the art, it will be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
