Abstract (en)
A counter-flow heat exchanger (100) including: a primary flow passageway (102) comprising a primary flow inlet (104), a primary flow outlet (106), and a plurality of primary flow subset passageways (108) therebetween; a secondary flow passageway (112) comprising a secondary flow inlet (114), a secondary flow outlet (116), and a plurality of secondary flow subset passageways (118) therebetween; and a heat exchanger core (120) comprising portions of the plurality of primary flow subset passageways (108) and the plurality of secondary flow subset passageways (118), the secondary flow passageway (112) being in thermal communication with the primary flow passageway (102) in the heat exchanger core (120), wherein the primary flow subset passageways (108) in the heat exchanger core (120) and the secondary flow subset passageways (118) in the heat exchanger core (120) are oriented such that primary fluid flow through the primary flow subset passageways (108) flows opposite secondary fluid flow through the secondary flow subset passageways (118).
