Description

Technical Field

[0001] The utility model belongs to the technical field of thermal insulation of vacuum thermal insulation cryogenic pressure vessels, and particularly relates to a thermal insulation material coating tooling for a small-volume cryogenic tank body. Background Art

[0002] The storage application of cryogenic liquids is inseparable from insulation technology, and vacuum multi-layer insulation is the most effective way in this field. The principle of vacuum multi-layer insulation technology is to arrange multiple insulation layers closely to form a vacuum environment. In such an environment, the air is extracted or sealed to achieve the purpose of reducing heat transfer. In vacuum multi-layer insulation technology, the surface flatness and overall looseness of the insulation material have a huge impact on the insulation performance of the entire cryogenic liquid. If the surface unevenness of the insulation material is high, it will cause local accumulation of heat, making the local temperature too high, which will lead to increased heat loss. Therefore, the flat surface can better absorb and diffuse radiant heat, reduce the difference in local temperature and improve the overall insulation effect.

[0005] In the above-mentioned existing technologies, their applications are concentrated on larger volume tanks that can be mounted on equipment. Small volume tanks have higher requirements for thermal insulation capacity, but they are currently covered manually; however, manual covering easily leads to uneven surfaces of the final thermal insulation material due to the thermal insulation material being pressed by fingers and palms.
