Description

TECHNICAL FIELD

[0001] The present application relates to a kind of accelerator power supply's conduction cooling structure, belongs to the field of ion accelerator. BACKGROUND

[0002] Accelerator power supply long-term operation, water cooling structure is the important component of its reliability, stable operation support.For the specification and variety of accelerator power supply, some thermal power is big, some thermal power is small, so its water cooling structure can cause water pipe, interface, process diversification.This makes the water cooling pipe installation, routing and maintenance work on site become relatively complex.At the same time, the quality and reliability of the consistency of the large number of water cooling structure is also difficult to guarantee.At the same time, accelerator cooling water is usually deionized water, in order to guarantee the heat dissipation requirement of different power supply, water pressure and flow have certain requirements, long time work, some water cooling structure, pipeline, joint is easy to aging, need regular replacement and maintenance, this requires the preparation of different water cooling structure corresponding spare parts.So, in order to facilitate maintenance, many different power supply water cooling structure needs to provide many types of spare parts.This also depends on the production of spare parts manufacturers, if due to the closure and other reasons can not produce the spare parts, you need to find manufacturers to design water cooling structure, the spare parts of the water cooling structure designed again, sometimes more difficult than spare parts, its reliability and applicability also need to spend time to verify, this increases the uncertainty of water cooling structure reliability invisibly.Obviously, the diversity of accelerator power supply water cooling structure not only increases the complexity of water cooling structure installation, maintenance, upgrade, but also increases the type and quantity of water cooling structure spare parts, at the same time, also increases the dependence on its manufacturers.

[0003] The fixed water cooling structure of the accelerator power supply is generally closely related to the circuit topology, and the circuit topology is determined when the water cooling structure is determined. Since the structure of the power supply is generally compact and the installation size is strict, the circuit or size is not allowed to be changed, otherwise the circuit cannot be installed. If the circuit is changed or upgraded, it is basically impossible. The only way is to redesign and process the structure. Moreover, the change of the structure will introduce unreliable factors, which need to be verified by experiments. From the perspective of reliability, the power supply structure can be divided into parts prone to problems and parts not prone to problems. Once the water cooling structure is verified, its stability is relatively high, and the circuit part is relatively prone to problems. However, the stability of the power supply is the overall evaluation, and the fixed water cooling structure cannot improve the reliability of the circuit part alone, and there is no possibility of quickly upgrading and optimizing the performance of the circuit. In addition, the heat dissipation efficiency of the traditional fixed water cooling structure is relatively low, and different power supplies usually use different water cooling parameters. At the same time, the traditional fixed water cooling structure needs to dissipate heat for power devices, reactors and transformer components respectively. The relative positions of some components are relatively far apart, and the installation and other problems also need to be considered, so the water cooling structure has problems such as inaccurate heat dissipation position and low heat dissipation efficiency. Generally, the heat dissipation of circuit components is different, and the fixed structure cannot adjust the heat dissipation efficiency according to different heat dissipation. Therefore, the fixed water cooling structure still has room for improvement in terms of heat dissipation efficiency and flexibility.

[0004] The accelerator power supply has a large number of types and specifications, and the water cooling structures of different power supplies not only differ from each other, but also have complex processes and cannot be produced industrially, so the quality, reliability and consistency cannot be guaranteed. Solving these problems is of great significance to the realization of the standardized power supply of the high-reliability accelerator and the construction of the new generation of future accelerators.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention are within the scope of protection of the present invention.

[0027] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0028] Since this invention proposes a conductive cooling structure for the standardized power supply of ion accelerators with water-electricity separation, the relevant content is described below to enable those skilled in the art to have a clearer understanding of the invention.

[0029] Ion accelerators typically consist of hundreds or even thousands of power supplies, mainly categorized into DC power supplies and pulsed power supplies. Classified by magnet type, they include dipole, tetrapole, hexapole, solenoid, superconducting, calibration, and scanning power supplies. These power supplies are specifically designed based on the magnet load parameters. Due to differences in magnet load parameters and the different functions of the power supplies within the accelerator, their internal structures are usually different. When different circuit topologies or operating principles are used, their internal structures, including water-cooling structures, vary considerably. This significantly increases the workload during the design, production, operation, maintenance, and upgrade phases. In most cases, different power supplies need to be designed for different magnets, and some power supplies require specialized personnel for repair, resulting in relatively low power supply maintenance efficiency. The design, production, operation, maintenance, and upgrade of power supply technology are highly dependent on manufacturers.

[0030] To meet the requirements of high reliability, high availability, high quality, and secure supply for accelerator power supplies, and to improve the efficiency of power supply design, production, processing, operation, and maintenance, some embodiments of this invention provide a water-electricity separation structure for ion accelerator power supplies. This structure separates the water and electricity in the ion accelerator power supply by setting up standard module units and conductive cooling units. Specifically, by combining and modifying the standard module units, the structure of different types and specifications of magnet power supplies and power source power supplies in ion accelerators is standardized, achieving standardization of ion accelerator power supplies. Conductive cooling of the standard module units is achieved by setting up a water-cooling unit inside the chassis and using a fastening unit to compress the standard module units, ensuring close contact between them. This invention simplifies and standardizes the production process, saves labor and production costs, improves the quality of power supply production and processing, increases the security of power supply supply, enhances the reliability of the power supply system, and meets the new demands of future next-generation accelerators for efficient, highly reliable, and highly available power supplies.

[0031] Example 1

[0032] like Figure 1a and Figure 1bAs shown, this embodiment provides a conductive cooling structure for an ion accelerator power supply, comprising: a chassis, and standard module units and a conductive cooling unit disposed within the chassis. The standard module unit includes at least one standard functional module detachably disposed within the chassis. Each standard functional module is connected to a backplate disposed on the rear panel of the chassis via a custom standard connector at its rear end, and is connected to the main controller via the backplate for communication. The conductive cooling unit includes at least two water-cooled plates adjacent to both sides of each standard functional module, and spring-loaded fastening plates disposed between the standard functional modules and the water-cooled plates. The inlet and outlet ports of each water-cooled plate are respectively connected to a main inlet pipe and a main outlet pipe disposed on the side of the chassis. Each spring-loaded fastening plate is used to press against each standard functional module, ensuring close contact between the standard functional module and the water-cooled plate, thereby cooling the standard functional module by the water-cooled plate.

[0033] Preferably, as shown in Figure 2 and Figure 3 As shown, each spring fastening plate has the same structure, and the upper and lower parts of the spring fastening plate are provided with several mounting holes for fastening connection with the standard functional module or water-cooling plate; the middle part of the spring fastening plate is provided with several springs, and the middle part of the standard functional module is provided with a corresponding convex rail. When the spring fastening plate is fastened to the standard functional module, the springs and the convex rail are pressed against each other to achieve a tight contact between the standard functional module and the water-cooling plate, thereby improving the heat dissipation efficiency.

[0034] Preferably, the spring clips on the spring clip fastening plate are arranged in an array on the spring clip fastening plate, and the number of them is determined according to the size of the standard functional module, preferably two rows or one row. Correspondingly, two or one convex rails are also provided on the standard functional module.

[0035] Preferably, such as Figure 4 As shown, the water-cooled plate includes a shell and a serpentine tube disposed inside the shell. The water inlet and water outlet of the serpentine tube are located at the upper and lower ends of one side of the water-cooled plate, respectively, and both the water inlet and water outlet are provided with internal threads for connecting the main water inlet pipe and the main water outlet pipe.

[0036] Preferably, such as Figure 5a and Figure 5b As shown, the main inlet and outlet water pipes are located on the rear sides of the chassis, respectively. A water pipe extends from the main inlet, connecting each water-cooled plate in series before entering the main outlet. Specifically, the water pipe from the main inlet enters through the inlet of the first water-cooled plate and exits through the outlet below it. Then, it enters through the outlet below the second water-cooled plate and exits through the inlet above it, sequentially entering the third water-cooled plate, thus forming a series connection of multiple water-cooled plates before finally entering the main outlet. The main inlet and outlet water pipes can be connected vertically depending on the number of chassis, allowing for the stacking of multiple chassis to provide water inlet and outlet.

[0037] Preferably, the standard functional modules are divided into two categories according to a preset power threshold (e.g., 2.5kW): a first standard functional module with power greater than the preset power threshold and a second standard functional module with power less than the preset power threshold. The height of the first standard functional module along the longitudinal direction of the chassis is twice that of the second standard functional module, and all other dimensions are the same.

[0038] Preferably, the first standard functional module and the second standard functional module are of the same type, both including a standard functional module body, a module handle disposed at the front end of the standard functional module body, and a custom standard connector disposed at the rear end of the standard functional module body. The standard functional module body includes a standard voltage module, a standard current module, and a discharge module.

[0039] To adapt to applications requiring rapid changes in current and voltage, the standard voltage module is mainly used to boost the voltage of the preceding stage as needed, enabling the superconducting magnet to accelerate the rapid rise or fall of current. Its voltage is adjustable within a certain range to meet the needs of different excitation voltage levels. The standard current module is mainly used to provide excitation current to the magnet, and its current magnitude is adjustable. The energy discharge module is mainly used to assemble the superconducting power supply, and after quench failure, it discharges energy from the load and the power supply internally to protect the circuit.

[0040] Preferably, an indicator light is provided in the center of the front panel of the standard function module to indicate the basic status of the standard function module, including fault, running and other statuses; a positioning pin is provided at the bottom of the front panel of the standard function module to lock the standard function module to the chassis for positioning when the standard function module is inserted into the chassis, and when the standard function module is to be removed, the handle is pressed down to retract the positioning pin so that the standard function module can be removed; a guide rail is provided at the bottom of the standard function module to reduce the friction when the standard function module is inserted into or removed from the chassis.

[0041] Preferably, the number of standard functional modules inside the chassis is set according to actual needs. For example, a chassis can accommodate 6 or 8 first standard functional modules, or 12 or 16 second standard functional modules. Since the volume of a first standard functional module is twice that of a second standard functional module, a chassis accommodating 6 first standard functional modules has the same size as a chassis accommodating 12 second standard functional modules, and a chassis accommodating 8 first standard functional modules has the same size as a chassis accommodating 16 second standard functional modules. The size of the chassis is related to the number of standard functional modules and can be flexibly adjusted according to requirements, but the width is usually an integer of TE, and the height is an integer multiple of U.

[0042] Example 2

[0043] like Figure 6The diagram illustrates the application of Embodiment 1. Five chassis are vertically stacked within the cabinet: two chassis containing eight first standard functional modules, one chassis containing sixteen first standard functional modules, one chassis containing six first standard functional modules, and one chassis containing twelve second standard functional modules. The main inlet and outlet water pipes within each chassis are connected to provide water supply to the standard functional modules within the multiple chassis. Each standard functional module within a chassis is connected to a backplane within the chassis and, through the backplane, to the main controller for communication, enabling series and parallel connections between different standard functional modules.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
