Abstract
Official abstract text for this publication.
A heat exchanger core includes: a first passage row which is formed by a plurality of first passages; a plurality of first dividing walls separating the plurality of first passages from each other; a second passage row which is disposed adjacent to the first passage row and is formed by a plurality of second passages; a plurality of second dividing walls separating the plurality of second passages from each other; and a partition wall located between the first passage row and the second passage row, and separating the plurality of first passages and the plurality of second passages. (a) The partition wall has a greater section modulus in an orthogonal direction than either the first dividing wall or the second partition, or (b) a constituent material of the partition wall has a greater breaking strength than a constituent material of either the first dividing wall or the second dividing wall.
First claim
Opening claim text (preview).
1 . A heat exchanger core, comprising: a first passage row which is formed by a plurality of first passages arranged along a reference plane; a plurality of first dividing walls disposed so as to intersect the reference plane and separating the plurality of first passages from each other; a second passage row which is disposed adjacent to the first passage row in an orthogonal direction of the reference plane and is formed by a plurality of second passages arranged along the reference plane; a plurality of second dividing walls disposed so as to intersect the reference plane and separating the plurality of second passages from each other; and a partition wall located between the first passage row and the second passage row in the orthogonal direction of the reference plane, and separating the plurality of first passages and the plurality of second passages, wherein (a) the partition wall has a greater section modulus in the orthogonal direction than either the first dividing wall or the second partition, or (b) a constituent material of the partition wall has a greater breaking strength than a constituent material of either the first dividing wall or the second dividing wall. 2 . The heat exchanger core according to claim 1 , wherein the partition wall has a larger thickness than either the first dividing wall or the second dividing wall. 3 . The heat exchanger core according to claim 1 , wherein either the first dividing wall or the second dividing wall includes a crack origination portion. 4 . The heat exchanger core according to claim 3 , wherein a pair of the adjacent first passages or the adjacent second passages communicate with each other via the crack origination portion.
