ENERGY CONVERSION STACK, ENERGY CONVERSION UNIT AND ENERGY CONVERSION DEVICE

摘要

To provide an energy conversion stack capable of efficiently recovering thermal energy converted from oscillation energy of gaseous medium.SOLUTION: An energy conversion stack comprises a conversion unit and a heat medium flow passage. The conversion unit has a columnar shape, a plurality of open holes penetrates the inside of the conversion unit over a bottom surface of a columnar body, and the conversion unit can mutually convert oscillation energy and thermal energy of gaseous medium in the plurality of open holes. The heat medium flow passage is provided so as to surround at least a part of the side surface of the conversion unit in a circumferential direction.SELECTED DRAWING: Figure 1
