Description
また、カバー部材の熱伝導率は、容器本体の表面側での熱伝導率よりも高いため、カバー部材によって熱を早く開放手段へ伝えることができる。
また、カバー部材には、複数の容器本体が内側に収容されているため、容器本体側から開放手段へ熱を伝えるための手段を、複数の容器本体の各々に個別に設けなくて済む。そのため、部品点数の増加を抑制した高圧容器とすることができる。
さらに、開放手段は、容器本体の長手方向の両端側に設けられていることで、カバー部材が加熱された場合に、熱源の位置がカバー部材に対して偏っていたとしても、熱源から近い方の開放手段に熱がより早く伝えられる。そのため、容器本体に収容された流体をより早く外部に放出することができる。
また、複数の容器本体の各々の放出部に対応して開放手段が設けられ、複数の容器本体が放出部を介して連通される連通手段が、カバー部材の内側に収容されることで、全ての容器本端の流体が、連通手段を介して、熱源から伝えられた熱によって最も早く開放された開放手段から放出される。そのため、カバー部材が加熱された場合に、複数の容器本体に収容された流体をより早く外部に放出することができる。
(燃料電池車両12の概略)
本高圧タンク10が適用された車両12は、駆動手段としての駆動モータ14を備えている。駆動モータ14は、例えば、車両12の車両後側部分に配置されている。また、駆動モータ14は、直接又は減速ギヤ列等の変速手段を介して間接的に車両12の駆動輪としての後輪16へ機械的に接続されており、駆動モータ14から出力された駆動力は、後輪16へ伝わるようになっている。
一方、図1に示されるように、高圧タンク10は、車両12における車両前後方向中間部における車両12の床部又は車体としてのフロアパネル20の車両下側に設けられている。図2から図4の各図に示されるように、高圧タンク10は、複数の容器本体としてのタンク本体22を備えている。これらのタンク本体22は、略円筒形状にされており、タンク本体22の長手方向(中心軸方向)は、車両前後方向とされている。また、これらのタンク本体22は、車幅方向に一列(一層)に並んで設けられている。しかも、これらのタンク本体22は、車幅方向に互いに接近された状態で敷詰められており、車幅方向に隣合うタンク本体22の間隔は、タンク本体22の外周部の直径寸法よりも充分に狭くされている。これによって、複数のタンク本体22は、全体的に車両上下方向に薄い扁平状となるように配置されている。
次に、本実施形態の作用並びに効果を説明する。
次に、第2の実施の形態について説明する。
