Abstract
A coolant preservation container having vacuum space in a peripheral portion of the interior thereof for making a container member adiabatic and a partition for dividing the container member into a plurality of chamber. Each chamber has ports from and via which a coolant is taken out from and returned to the chamber. These ports are suited to circulate a coolant contained in the chamber on external cooling trap.
Claims18
A coolant preservation container comprising:
- an outerwall defining an enclosed space therein;
- an innerwall provided within said enclosed space and defining a container member therein;
- means defining at least one vacuum space formed between said outerwall and said innerwall for making said container member adiabatic;
- a partition comprised of a single, thermally conductive plate dividing said container member into a plurality of individual closed chambers;
- and
- at least one port provided on each individual closed chamber for introducing a cryogenic liquid into each individual closed chamber and/or for discharging the cryogenic liquid from each individual closed chamber.

A container for storing coolant comprising:
- an outer shell;
- an inner shell disposed within and spaced apart from the outer shell to define an enclosed space within the outer shell;
- partition means comprised of a thermally conductive plate for dividing the enclosed space into a plurality of individual closed chambers and for equalizing the temperature of coolant stored in adjacent individual closed chambers by thermal conduction of heat energy through the thermally conductive plate, each individual closed chamber having means for charging coolant thereto and discharging coolant therefrom;
- and insulation means disposed between the outer and inner shells for thermally insulating the individual closed chambers from the outside.
