Title:
HEAT EXCHANGER
Document Type and Number:
Japanese Patent JP2023073882
Kind Code:
A
Abstract:
To provide a heat exchanger enabling suppression of increase in pressure loss due to distribution of fluid even when the heat exchanger is formed in such a manner that a plurality of kinds of flow channel openings are formed in a mixed manner in a core surface.SOLUTION: A heat exchanger 100 comprises: a core portion 1 having a core surface 12 in which a plurality of flow channel openings 13 are arranged in a matrix state; and a phase adjustment portion 2 including a plurality of passages 21 respectively connected to the plurality of flow channel openings 13 and disposed in the core surface 12. The plurality of flow channel openings 13 are arranged in the core surface 12 in a manner that arrangement patterns for each kind of fluid are same in each row, and phases of the arrangement patterns for each row are not the same. The plurality of passages 21 of the phase adjustment portion 2 include inclined passage rows 23a inclined in a row direction to align the phases of the arrangement patterns of each row. In the phase adjustment portion 2, the other end openings 22 of the passages 21 for each kind of fluid are formed by a unit of line by arranging the passages 21 in which the fluid of the same kind flows, in the line direction.SELECTED DRAWING: Figure 6
