REACTION VESSEL, HEAT STORAGE SYSTEM, AND CRAMPING FRAME

PROBLEM TO BE SOLVED: To effectively inhibit expansion of a heat storage material.SOLUTION: A reaction vessel includes: a plurality of heat storage materials which generate heat by bonding with a reaction medium, or which store heat by elimination of the reaction medium; a heat exchange part which is laminated on one side of the heat storage materials and performs heat exchange with the heat storage materials; and a cramping frame including a plurality of first frames respectively surrounding the heat storage materials when viewed in a lamination direction of the heat exchange part and the heat storage materials, and a second frame surrounding the first frames when viewed in the lamination direction.SELECTED DRAWING: Figure 8 【課題】蓄熱材の膨張を効果的に抑制する。【解決手段】反応器は、反応媒体と結合して発熱する、又は反応媒体が脱離して蓄熱する複数の蓄熱材と、前記蓄熱材の片側に積層され、前記蓄熱材との間で熱交換する熱交換部と、前記熱交換部と前記蓄熱材との積層方向に見て前記複数の蓄熱材のそれぞれを囲む複数の第一枠と、前記積層方向に見て前記複数の第一枠を囲む第二枠と、を有する拘束枠と、を備えている。【選択図】図８
