FIRE SAFETY APPARATUS OF HIGH-PRESSURE GAS FUEL TANK

摘要

PURPOSE: A fire safety apparatus of a high-pressure gas fuel tank for a vehicle is provided to evacuate the high-pressure gas fuel tank before the high-pressure gas fuel tank is damaged in a fire. CONSTITUTION: A fire safety apparatus of a high-pressure gas fuel tank for a vehicle comprises a pressure actuator(30) and a storage medium(50). The pressure actuator is installed around a high-pressure gas fuel tank(1) and operated to connect or cut off a tank connection channel(3a) and an outside connection channel(3b) according to pressure changes. The storage medium contains a thermal reactive material that creates pressure through thermal phase-change in the event of a fire and is installed in connection with the pressure actuator around the high-pressure gas fuel tank.
