Abstract (en)
[origin: US2021180870A1] A component for a heat exchanger can comprise a body including a ceramic and can have a central cavity extending along a length of the body; a plurality of spirals extending around the central cavity; a plurality of interspiral channels disposed between the plurality of spirals; a plurality of intraspiral channels contained within the plurality of spirals; wherein a twist angle of each spiral of the plurality of spirals in relation to a length direction of the body is varying. The heat exchanger component can be used for making a heat exchanger having three flow paths and can reach an exceptional efficiency while allowing an economic manufacturing.
