摘要:
A novel tank cryogenic-compatible composite pressure vessel that beneficially utilizes Vapor Cooled Shielding (VCS) is introduced to minimize thermal gradients along support stmctures and reduces heat loads on cryogenic systems. In particular, the configurations and mechanisms to be utilized herein include: providing for a desired number of passageways and a given thickness of the VCS, reducing the thermal conductivity of the VCS material, and increasing the cooling capacitance of the hydrogen vapors.

Embodiments are directed to compressed gas storage units exhibiting one or more safety features. Particular embodiments employ a pressure relief mechanism to rapidly yet safely vent the contents of the tank in the event of a fire. The mechanism may comprise an internally piloted relief valve in communication with temperature-sensitive element(s) present along the tank dimensions. Under high temperature conditions indicative of a fire, the element communicates a signal to open the internally piloted relief valve. In some embodiments the element is configured to communicate a heat signal (e.g., by thermal conduction). In certain embodiments the element is configured to communicate a pressure change signal (e.g., pneumatic, hydraulic). In other embodiments the element may communicate different signal types, such as electric (e.g., thermoelectric) or mechanical (e.g., shear or tension forces). Also disclosed is a module incorporating a plurality of tanks to offer enhanced storage capacity.

Vorrichtung zum Schutz eines Hochdruckgasbehälters (10) eines Kraftfahrzeugs mit einer intumeszierenden Schicht (20). Die intumeszierende Schicht (20) ist derart angeordnet und ausgebildet, dass die intumeszierende Schicht (20) den Hochdruckgasbehälter (10) zumindest teilweise abschirmt. Die intumeszierende Schicht (20) weist ein intumeszierendes Elastomermaterial auf.
摘要:
The invention relates to a liquid gas storage site comprising a closed concrete shield (1) for accommodating a tank (2), the walls of which are located at a distance from the inner wall of the concrete shield (1), the inside of the concrete shield (1) being provided with a steel sheet lining (3) in the wall region. The invention is characterized in that the lining (3) is formed from thin steel sheet strips (6), the adjacent edges (6.1) of which are gas-tightly joined together using a clamping connection.
摘要:
A composite pressure vessel and method of manufacture. A composite pressure vessel comprises a multi-component mandrel that is integrated into the vessel, thereby becoming a permanent part of the pressure vessel, and comprises a cylinder and dome ends. Dome ends are made from custom molds with a fiber reinforced polymer. Components of the mandrel may be pieced together with a joining resin. The mandrel comprises a permeation barrier coated on the inside by spraying with elastomer resin, for example. Filaments are wound onto the mandrel, allowing any length of cylinder section to be made for the pressure vessel.
