[0044] 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 embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Here is an explanation of the terms used in the text:

[0046] Superconducting magnets: Superconducting magnets are electromagnets made by using superconductors with specific transition temperatures and particularly high critical magnetic fields to form coils at low temperatures. Their main characteristics are that there is no electrical loss caused by the resistance of the wires, nor is there any magnetic loss caused by the presence of an iron core.

[0047] Superconducting coil: A coil made of coils made of superconducting tape is called a superconducting coil. There is no resistance or Joule energy loss in a superconducting coil, so once a current is superimposed, the current can exist indefinitely, and the magnetic field it generates can be maintained indefinitely without external work.

[0048] Liquid nitrogen: Liquid nitrogen refers to nitrogen gas in liquid form. In industrial production, liquid nitrogen is obtained by fractional distillation of compressed liquid air. It can be used as a deep refrigerant to provide the temperature required for high-temperature superconductors to exhibit superconductivity, such as yttrium barium copper oxide.

[0049] Thermal cutoff components: These are structures in superconducting magnets used to cool heat sources such as current leads and main support structures.

[0050] Normal heat flux: Heat flux (or thermal flux density) is a vector quantity with directionality. Its magnitude equals the amount of heat flowing through a unit area per unit time along this direction. The direction is along the normal to the isothermal surface, pointing from the high-temperature direction to the low-temperature direction. The unit is W / m². 2 It can characterize the degree and direction of heat transfer.

[0051] Topology optimization is a mathematical method that optimizes the distribution of materials within a given region based on given load conditions, constraints, and performance indicators. It is a type of structural optimization.

[0052] Draft angle: It is an angle designed for molds. More precisely, it is the draft angle of the molded part of the mold in the direction parallel to the mold exit direction.

[0053] Parameter optimization: Parameter optimization is a method to achieve design goals. By parameterizing the design goals, optimization methods are used to continuously adjust the design variables so that the design results continuously approach the parameterized target values.

[0054] Volume fraction: Applying a 30% volume fraction means that the volume of the optimal design must be less than or equal to 30% of the original volume.

[0055] Based on the background information, during the invention process of this application, the inventors discovered that the design of existing heat-blocking components relies on the original structural configuration and engineers' experience, and even after multiple iterations of design, there is a possibility that they may not be able to meet the design requirements.

[0056] Based on this, embodiments of the present invention provide a design method for a thermal cutoff component of an ultracryogenic component, which optimizes the distribution position and shape of the thermal cutoff component. Specifically, the optimal distribution position of the thermal cutoff component is determined by a structural topology optimization method, and the optimal shape of the thermal cutoff component is determined by a structural parameter optimization method, so that the external heat is transferred to the superconducting coil as little as possible.

[0057] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0058] refer to Figure 1 , Figure 1 This is a flowchart illustrating a design method for a cryogenic component thermal cutoff part according to an embodiment of the present invention. The design method for the cryogenic component thermal cutoff part includes:

[0059] S101: Establish the design domain for the thermal cutoff component on the main support structure connecting the liquid nitrogen chamber and the external Dewar chamber.

[0060] S102: Obtain the target distribution location of the thermal cutoff component through thermo-coupling topology analysis.

[0061] S103: Perform parametric modeling at the target distribution location.

[0062] S104: Perform parameter optimization to obtain the target shape of the thermal cutoff component.

[0063] S105: Verify the thermal cutoff component with the target shape located at the target distribution position.

[0064] In this step, a thermo-mechanical coupling analysis is performed on the heat cut-off component with the target shape located at the target distribution position to verify whether the heat cut-off component meets the requirements of temperature field (i.e., normal heat flux not greater than 45W) and stress field (maximum Mises stress not exceeding 85% of the material yield strength).

[0065] Specifically, in this embodiment, the design method of the ultracryogenic component heat cut-off part optimizes the distribution position and shape of the heat cut-off part. Specifically, the optimal distribution position of the heat cut-off part is determined by the structural topology optimization method, and the optimal shape of the heat cut-off part is determined by the structural parameter optimization method, so that the external heat is transferred to the superconducting coil as little as possible.

[0066] Optionally, in another embodiment of the invention, reference is made to... Figure 2 , Figure 2 A flowchart illustrating another design method for a thermal cutoff component of an ultra-cryogenic component provided in an embodiment of the present invention.

[0067] One possible way to achieve step S102, "obtaining the target distribution location of the thermal cutoff component through thermo-coupled topology analysis," is as follows:

[0068] S1021: Set the working temperature and mechanical boundary conditions at both ends of the main support structure, and fix the main support structure to the room temperature connection end; take the normal heat flux of the middle section of the main support structure and the weight of the heat cut-off component as optimization objectives, and take the material volume fraction not exceeding the first threshold and the maximum Mises stress of the material not exceeding the second threshold as constraints. At the same time, multiply the Young's modulus, density and heat capacity of the design domain with the topology optimization penalty function to perform topology optimization iterative design, and obtain the target distribution position of the heat cut-off component.

[0069] Specifically, in this embodiment, thermo-mechanical coupling boundary conditions are applied, that is, the working temperature and mechanical boundary conditions at both ends of the main support structure are set. For example, the initial room temperature is set to 293.15K and the low temperature position temperature is 20K. The connection end between the main support structure and the room temperature is fixedly constrained. The normal heat flux of the middle section of the main support structure (e.g., the plane 28mm away from the room temperature connection end) (requiring the normal heat flux of the middle section of the main support structure to be as small as possible) and the weight of the heat cut-off component (requiring the weight of the heat cut-off component to be as light as possible) are used as optimization objectives. The material volume fraction not exceeding a first threshold (e.g., 30%) and the maximum Mises stress of the material not exceeding a second threshold (e.g., 85%) are used as constraints. At the same time, the Young's modulus K, density ρ, and heat capacity C of the design domain are multiplied with the topology optimization penalty function to perform topology optimization iterative design and obtain the optimal distribution position of the heat cut-off component, that is, the target distribution position mentioned above.

[0070] Optionally, in another embodiment of the invention, reference is made to... Figure 3 , Figure 3 This is a flowchart illustrating another design method for a thermal cutoff component of an ultra-cryogenic component provided in an embodiment of the present invention.

[0071] One possible way to implement "perform parametric modeling at the target distribution location" in step S103 is as follows:

[0072] S1031: Parametric modeling is performed at the target distribution location based on the length, width, height, draft angle, and fillet radius of the heat cut-off component.

[0073] Specifically, in this embodiment, parametric modeling is performed at the optimal distribution position of the heat cut-off component obtained in step S102, mainly including the length L, width W, height H, draft angle θ, and fillet R of the heat cut-off component.

[0074] Optionally, in another embodiment of the invention, reference is made to... Figure 4 , Figure 4 This is a flowchart illustrating another design method for a thermal cutoff component of an ultra-cryogenic component provided in an embodiment of the present invention.

[0075] One possible way to achieve step S104, "performing parameter optimization to obtain the target shape of the thermal cutoff component," is as follows:

[0076] S1041: Set the working temperature and mechanical boundary conditions at both ends of the main support structure, and fix the main support structure to the room temperature connection end; take the normal heat flux of the middle section of the main support structure as the optimization target, and take the range of variables in the parametric modeling as the constraint condition, and perform structural parameter optimization design to determine the target shape of the heat cut-off component.

[0077] Specifically, in this embodiment, thermo-coupling boundary conditions are applied, that is, the working temperature and mechanical boundary conditions at both ends of the main support structure are set. For example, the initial room temperature is set to 293.15K and the low temperature position temperature is 20K. The connection end between the main support structure and the room temperature is fixedly constrained. The normal heat flux of the middle section of the main support structure (e.g., the plane 28mm away from the room temperature connection end) is used as the optimization target (the normal heat flux of the middle section of the main support structure is required to be as small as possible). The constraint conditions are designed as the upper and lower bounds of the variables in the parametric modeling of the heat cut-off component (e.g., 5mm < length L < 10mm, 2mm < width W < 8mm, 2mm < height H < 8mm, 0° < draft angle θ < 30° and 0 < fillet R < 5mm). The structural parameters are optimized to determine the optimal shape of the heat cut-off component, that is, the target shape mentioned above.
