<P>PROBLEM TO BE SOLVED: To provide a heat storage device of high efficiency by improving utilization factor of a heat storage agent. <P>SOLUTION: This heat storage device is constituted by successively stacking a heat storage panel 8 having a primary-side fluid flow channel and a flow channel flat plate 13 having a secondary-side fluid flow channel through a heat reservoir 11, and the heat reservoir 11, the heat storage panel 8 and the flow channel flat plate 13 are closely kept into contact with each other. The heat reservoir 11 is held between the heat storage panel 8 having the primary-side fluid flow channel and the flow channel flat plate 13 having the secondary-side fluid flow channel and stacked, thus the heat storage agent can be packed with high concentration, the heat of a heat source can be directly transferred to the heat reservoir 11, and the heat can be taken in and out to the heat storage agent with high efficiency. <P>COPYRIGHT: (C)2007,JPO&INPIT |
