AI Technical Summary
Traditional cryogenic storage containers are prone to settling and compaction under vibration loads and repeated thermal cycling, resulting in the failure of the interlayer insulation and a lack of effective control over radiative heat transfer. This leads to vaporization and pressurization of the inner medium, posing a safety hazard.
The system employs a multi-layered insulation layer composed of radiation shielding panels and fiberglass paper, arranged parallel to the outer wall of the inner liner, and combined with a high-vacuum interlayer to prevent heat transfer through convection, conduction, and radiation. A support frame is installed between the inner liner and the jacket to increase stability, and the pipe assembly provides safe pressure relief.
It effectively reduces the temperature of the inner liner, prevents the medium from vaporizing and pressurizing, improves the safety of the container, and is suitable for the safe transportation of highly toxic media. It solves the problems of insulation failure and safety hazards of traditional containers.
