Embodiment 1

[0027] In Embodiment 1 of the present invention, in combination with figure 1 and figure 2 As shown, the conduction cooling large-scale high-temperature superconducting magnet structure includes a coil former 1, a single high-temperature superconducting coil group 2 wound on the coil former 1, and a cooling channel assembly 3; the coil former 1 and the high-temperature superconducting coil group 2 A first insulating layer A is arranged between them to prevent electrification of the coil skeleton; the high temperature superconducting coil group 2 is provided with an electrical connection component 4, and the electrical connection component 4 is used to excite the high temperature superconducting coil group 2; the cooling channel component 3 and the high temperature A second insulating layer B made of thermally conductive material is arranged between the superconducting coil groups 2 to prevent the cooling channel assembly 3 from being electrified as a whole; The outer surface...

Embodiment 2

[0032] Such as Figure 4 As shown, the difference between Embodiment 2 and Embodiment 1 mainly lies in that the conduction-cooled large-scale high-temperature superconducting magnet structure in this embodiment includes six high-temperature superconducting coil groups 2, and there is cooling between adjacent high-temperature superconducting coil groups 2. The plates 7 are electrically connected to the adjacent high-temperature superconducting coil groups 2 through the electrical connection assembly 4 . Including six stacked high-temperature superconducting coil groups 2 is a preferred illustration of this embodiment in conjunction with the accompanying drawings. In practical applications, the high-temperature superconducting coil group 2 is not limited to six, and there may be more or fewer , is not limited.

Abstract

The invention provides a conduction cooling large-scale high-temperature superconducting magnet structure. The conduction cooling large-scale high-temperature superconducting magnet structure comprises a coil framework, a high-temperature superconducting coil group and a cooling channel assembly, wherein the high-temperature superconducting coil assembly is provided with an electric connection assembly, and the electric connection assembly is used for exciting the high-temperature superconducting coil assembly; a second insulating layer made of a heat conduction material is arranged between the cooling channel assembly and the high-temperature superconducting coil assembly and is used for preventing the cooling channel assembly from being wholly electrified; two sides of the second insulating layer are in thermal contact with the high-temperature superconducting coil assembly and the cooling channel assembly respectively; the cooling channel assembly is provided with a gas inlet used for inputting low-temperature helium and a gas outlet used for discharging the low-temperature helium. The structure is simple in structure, easy to process and suitable for conduction cooling of large-scale high-temperature superconducting magnets; The large-scale high-temperature superconducting magnet adopting the structure has better temperature uniformity in the operation process, the cooling effect is improved, and the refrigeration cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of superconducting magnets, in particular to a conduction cooling large-scale high-temperature superconducting magnet structure. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] Strong magnetic field technology has a wide range of applications in the fields of industry, medical treatment, national defense and scientific research. For magnets wound with ordinary wires, the increase in magnetic field strength is limited due to the limitation of Joule heat generated by the operating current. For magnets wound with superconducting wires (ribbons), the running current does not generate Joule heat, and the magnetic field strength can be greatly increased. Superconducting magnets have broad application prospec...
