A high efficiency heat accumulator according to the present invention comprises a heat accumulator frame having an inlet and an outlet for gas; and a heat exchanging member which is mounted in the heat accumulator frame and has an internal flow path of a branched tree structure in order to reduce pressure drop of gas passing under a constant volume condition. On the assumption that the heat accumulator of the present invention has the same volume, and the same flow rate and temperature of induced gas as those of the conventional heat accumulator, because the internal flow path of the heat exchanging member which is a heat accumulating body has the branched tree structure, to which the constructal law is applied, and is reduced in size at a fixed ratio whenever the internal path is branched, the high efficiency heat accumulator remarkably reduces pressure loss of passing gas in comparison with the conventional heat accumulator. |
