Abstract
The present disclosure relates to a vacuum heat-insulation device for a large low-temperature tank, the vacuum heat-insulation device having excellent heat insulation properties and vacuum stability by using a low-temperature heat-insulating material maintained in a vacuum at all times so as to store an ultra-low-temperature liquefied gas such as liquid nitrogen (LN2) or liquid hydrogen (LH2), and to a vacuum heat-insulation device for a low-temperature tank, the vacuum heat-insulation device having a flexible structure in which a vacuum jacket is partially contractible according to contraction of a low-temperature tank or a low-temperature heat-insulating layer.
Claims20
A vacuum heat-insulation device for a low-temperature tank, the vacuum heat-insulation device comprising:
- a low-temperature tank having a storage space for accommodating an ultra-low-temperature fluid therein;
- a low-temperature heat-insulation layer provided to surround an outer shell of the low-temperature tank;
- and
- a vacuum jacket having an internal space maintained in a vacuum state and sealed to surround an outer surface of the low-temperature heat-insulation layer to maintain airtightness with the outside,
- wherein the vacuum jacket has a flexible structure in which at least a portion thereof is contracted or expanded.
