Abstract
A tube-array-type liquid nitrogen container includes a container body having a mouth; a tube array component received in the container body; and a top cap sealing the mouth from above. The top cap is rotatable in the mouth. The tube array component is composed of a plurality of holding tubes. The holding tube is opened at one end thereof, wherein the opening thereof faces the top cap. The top cap has at least one tube access passing therethrough. Each tube access is atop covered by a tube access cover. The tube-array-type liquid nitrogen container uses a tube-array component composed of the a plurality of holding tubes to store the freezing tubes, and is cooperated with the rotatable top cap and an external robotic arm, thereby improving space utilization and thermal insulation, effectively ensuring safety of the freezing tubes, and facilitating automatic storage of freezing tubes.
