GAS STORAGE TANK AND IT'S MANUFACTURING METHOD

摘要

PURPOSE: A gas-storage tank and a manufacturing method thereof are provided to improve the heat transfer efficiency by increasing heating area between tubes a hydrogen storage alloy and a heat-exchanging medium are flowed filled in the gas-storage tank. CONSTITUTION: A gas-storage tank is composed of a heat-exchanging unit(50), a hydrogen storage alloy, a housing(70), and an end cap(80). The heat-exchanging unit is composed of a radiation plate(10), a tube(20) inserted in the radiation plate to make the heat-exchanging medium flowed, an inlet pipe(31), and an end plate(30) which has an outlet pipe(32) for exhausting hydrogen gas. The hydrogen storage alloy is filled in the heat-exchanging unit. The housing is arranged outside the heat-exchanging unit. A gas entry pipe and a gas outlet pipe are penetrated in the end cap. The end cap is combined to both ends of the housing with an inlet pipe(81) and an outlet pipe(82).
