A LOW HEAT LOSS CRYOGENIC LIQUID CONTAINER

摘要

The present invention provides a low-thermal loss low-temperature liquid container including: an outer container of which an upper part is connected to an upper cover and an internal space is at a vacuum atmosphere; an inner container positioned inside the outer container to be separated from an inner lateral wall of the outer container and receiving a low-temperature liquid; a liquid intake and discharge pipe connecting the outside of the outer container and the inside of the inner container and functioning as a passage for filling or extracting the low-temperature liquid; and a support unit positioned between an inner bottom surface of the outer container and the underside of the inner container and having a support shaft member made of a low-conductive material for the prevention of thermal conduction and a spring positioned in at least one among a position between a top surface of the supporting shaft member and the underside of the inner container, a position between the underside of the supporting shaft member and the underside of the outer container, and a position between both ends of the supporting shaft member. The purpose of the present invention is to provide the low-thermal loss low-temperature liquid container capable of improving structural stability and minimizing conductive heat transmission through the support unit.
