HEAT/ACOUSTIC WAVE CONVERSION COMPONENT AND HEAT/ACOUSTIC WAVE CONVERSION UNIT

摘要

Provided are a heat/acoustic wave conversion component having a honeycomb structure and with improved startability to convert heat/acoustic waves, and a heat/acoustic wave conversion unit. A heat/acoustic wave conversion component includes a partition wall 11 that defines a plurality of cells 14, inside of the cells being filled with fluid that oscillates to transmit acoustic waves, the heat/acoustic wave conversion component mutually converting heat exchanged between the partition wall 11 and the fluid and energy of acoustic waves resulting from oscillations of the fluid. The plurality of cells have an average of hydraulic diameters HDs that is 0.4 mm or less in a plane perpendicular to the cell extending direction, the heat/acoustic wave conversion component 1 has an open frontal area at each end face of 60% or more and 93% or less, and distribution of hydraulic diameters HDs of the plurality of cells has relative standard deviation that is 2% or more and 30% or less.
