Hydrogen storage container
View Patent ↗A hydrogen storage container that stores hydrogen gas using a hydrogen storage material capable of storing hydrogen gas includes: a hollow liner that stores the hydrogen gas and includes a liner opening portion into which the hydrogen gas is introduced; a hollow sub-tank disposed inside the liner to house the hydrogen storage material; a heat exchange pipe which is disposed inside the sub-tank and through which a heat exchange medium passes; a sub-tank support portion that supports an end portion of the sub-tank relative to the liner opening portion and supports an end portion of the heat exchange pipe; and a heat exchange medium passage that is formed to penetrate the sub-tank support portion and leads the heat exchange medium to the heat exchange pipe.
1. A hydrogen storage container that is configured to store hydrogen gas using a hydrogen storage material capable of storing hydrogen gas, the hydrogen storage container comprising:
a hollow liner that is configured to store the hydrogen gas and includes a liner opening portion into which the hydrogen gas is introduced;
a hollow sub-tank disposed inside the liner to house the hydrogen storage material;
a heat exchange pipe which is disposed inside the sub-tank and through which a heat exchange medium passes;
a sub-tank support portion that supports an end portion of the sub-tank relative to the liner opening portion and supports an end portion of the heat exchange pipe; and
a heat exchange medium passage that is formed to penetrate the sub-tank support portion and leads the heat exchange medium to the heat exchange pipe, wherein
the liner includes a pair of liner opening portions,
the sub-tank is supported by the respective liner opening portions at both ends via a pair of sub-tank support portions,
respective end portions of the heat exchange pipe are inserted into the heat exchange medium passage and supported by the respective sub-tank support portions, and
each of the respective sub-tank support portion is provided with a hydrogen gas passage, the hydrogen gas passage being configured to allow the hydrogen gas to enter and exit therethrough.

the sub-tank is supported by the respective liner opening portions at both ends via a pair of sub-tank support portions,
respective end portions of the heat exchange pipe are supported by the respective sub-tank support portions, and
the heat exchange pipe includes:
a pipe spiral portion that bends from a pipe base end portion projecting from one of the sub-tank support portions and extends in a coil shape; and
a pipe reciprocating portion that bends from a tip end of the pipe spiral portion, extends in a U shape on an inner side of the pipe spiral portion, and has a pipe tip end portion on a tip end thereof that is inserted into the other sub-tank support portion.
3. The hydrogen storage container as defined in claim 1 , wherein
the heat exchange pipe includes a plurality of pipe projections that extend in a lengthwise direction of the heat exchange pipe, and
the heat exchange pipe has a cross-sectional shape in which the plurality of pipe projections project radially toward an outer periphery of the heat exchange pipe.
4. The hydrogen storage container as defined in claim 3 , wherein the pipe projections extend spirally in the lengthwise direction of the heat exchange pipe.
