THREE-DIMENSIONAL SHELL STRUCTURE, PRESSURE VESSEL HAVING SAME, AND MANUFACTURING METHOD THEREFOR

摘要

Disclosed is a pressure vessel for storing and keeping fluid and a three-dimensional shell structure used therefor. The pressure vessel has a shell structure in which an inner part is divided and partitioned into two sub volumes which are twisted with each other, by the interface and sub volumes are continuous, as a main body of the pressure vessel, and two sub volumes are independently utilized as a storage space of a high pressure vessel or a space for receiving or moving a heat exchange medium.
