Document Type and Number:
WIPO Patent Application WO/2021/059877
Kind Code:
A1
Abstract:
This heat exchanger (100) is provided with a flow passage layer (10) in which a first flow passage (11) extending in a first direction and a second flow passage (12) extending in a second direction are disposed in the same layer. The first flow passage and the second flow passage respectively have flow passage cross-sectional areas which decrease and inrease in the extending direction of the flow passages. The first flow passage and the second flow passage cross in the same layer in first portions (23, 33) having reduced flow passage cross-sectional areas due to the displacements of the first portions (23, 33) in a third direction.
