Storage vessel for extremely low temperature material with cryogenic jacket
A storage vessel for an extremely low temperature material for reducing a vaporization rate by forming a plating layer at an outer surface of a discharge pipe thereof is provided. The storage vessel for an extremely low temperature material includes an inner container configured to store an extremely low temperature material of a liquefied state through a supply pipe in an inner receiving space; an outer container installed at a separated space at the outside of the inner container and having a vacuum port configured to enable the separated space to be a vacuum state; and a heat insulating member installed in a vacuum region between the inner container and the outer container to block a heat from being transferred to the inner container, wherein a discharge pipe connected to an outlet of the inner container and configured to vaporize and discharge an extremely low temperature material is disposed between the inner container and the outer container, and at an outer surface of the discharge pipe, a thermally conductive layer coated with a highly conductive material having high thermal conductivity is formed. By a such a configuration, a heat applied to an outer container can be effectively blocked from being transferred to an inner container for storing an extremely low temperature material, and by reducing a vaporization rate of the extremely low temperature material by increasing a heat transfer area of a discharge pipe, a loss rate according to vaporization of the extremely low temperature material can be reduced and a separate cheap auxiliary extremely low temperature material in addition to the extremely low temperature material can be subsidiarily used for fuel or industrial use.
DELIVERY TANK WITH PRESSURE REDUCTION, SATURATION AND DESATURATION FEATURES
A cryogenic delivery tank includes a vessel having inner and outer shells and an interior that may contain a cryogenic liquid with a headspace above.

Cellular load-responsive multilayer insulation
An insulation panel includes a face sheet hermetically coupled to a plurality of structural walls to define a plurality of cell bodies, with each cell body positioned contiguously with an adjacent cell body. An insulation structure is disposed within each cell body and further includes a first radiant barrier layer, a second radiant barrier layer, and a spacer disposed between the first radiant barrier layer and the second radiant barrier layer. Sealed cells formed by completing the cell bodies may contain a gas that condenses or freezes in response to cryogenic cooling of a structure to which the insulation panel is coupled. Load-responsive spacers may also be disposed between the insulation structure and the face sheet to support the face sheet while in atmospheric conditions and to disengage from the face sheet in low pressure environments, such as space.
