Opposed louver flaps in corrugated strips boost rotary air heat exchanger transfer while lowering flow resistance, material use, and fan demand.
A heat accumulator structure uses a medium flushing device to generate cold and hot flushing flows between storage elements.
A movable second heat transfer member passes through a slot in a first member to enable direct thermal conduction.
Offset beveled foils redirect fluid flow while foil bridges reduce transverse thermal conduction loss in thermoacoustic transducers.
Draining bulk material during the cold phase prevents thermal expansion damage to grates and reduces erosion in steelmaking regenerators.
