Title:
HIGH-VACUUM MULTI-LAYER FLEXIBLE THERMAL INSULATION TUBE FOR HIGH-TEMPERATURE SUPERCONDUCTING CABLE AND FABRICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/267417
Kind Code:
A1
Abstract:
A high-vacuum multi-layer flexible thermal insulation tube for a high-temperature superconducting cable and a fabrication method, the flexible thermal insulation tube comprising an outer tube (15), an inner tube (14), and an interface flange (7). The flexible thermal insulation tube further comprises: a vacuum interlayer (1), which is located between the inner tube and the outer tube; a multi-layer thermal insulation material (2), which is located on the side of the vacuum interlayer close to an outer wall of the inner tube for thermal insulation; and protrusions (3) are provided on the outer wall of the inner tube so as to reduce the contact area between the multi-layer thermal insulation material and the outer wall of the inner tube. The contact area between the thermal insulation material of the flexible thermal insulation tube and the outer wall of the inner tube is small, the evacuation efficiency is high, and the thermal insulation performance is good. Moreover, in the fabrication method, heat leakage data of different thermal insulation tubes is accurately calculated and simulated, which provides a strong guarantee for the design of thermal insulation tubes and the verification of the performance of thermal insulation tubes.
