THREE-DIMENSIONAL SHELL STRUCTURE, PRESSURE VESSEL PROVIDED WITH THE SAME AND FABRICATION METHOD THEREOF

摘要

The present invention relates to a pressure vessel for storage and storage of fluid, and a three-dimensional shell structure used therein. The three-dimensional shell structure is a three-dimensional shell structure for a pressure vessel divided into two sub-spaces consisting of a first sub-space and a second sub-space in which the interior is twisted by an interface, among the two sub-spaces. At least one is provided as a storage space for accommodating a fluid, and is sealed with a shielding plate except for a portion for carrying in/out of the fluid among portions exposed to the outside of the subspace provided as the storage space. In the case of the pressure vessel according to the present invention, a shell structure in which the interior is divided into two subvolumes in a twisted form by an interface and each sub-space is continuous is composed of the pressure vessel body. Meanwhile, by independently utilizing the two sub-spaces as a storage space for high-pressure fluid or a space for receiving or moving a heat exchange medium, the wall thickness is thin and the storage volume to weight is large, while having excellent pressure resistance characteristics, and at the same time, excellent specific surface area. , Fluid permeability and heat transfer properties. In addition, when the interface is configured in TPMS, it is particularly advantageous in terms of the stability of the high-pressure vessel. In addition, regardless of the external shape of the container, the geometric structure of the shell structure such as TPMS or the characteristics required for the pressure container can be satisfied or improved by the separation of the internal space. Restrictions can be remarkably alleviated, and the shape of the vessel can be freely designed, so when applied to a mobile pressure vessel, the functionality or appearance characteristics based on the shape can be greatly improved.
