PURPOSE:To obtain the heat exchanger having high strength and reliability by a method wherein fins having a plurality of communicating ports and bulkheads having communicating ports are laminated alternately to form orthogonally intersecting flow paths for two kinds of fluid. CONSTITUTION:The platelike fins 8 having a plurality of communicating ports 9 made by blanking and a plurality of bulkheads 10a-10n having communicating ports 11 are laminated and adhered alternately. The bulkheads 10a-10n are disposed in parallel with predetermined intervals. According to this constitution, the orthogonally mutually intersecting flow paths, consisting of the flow paths 12 between the bulkheads 10a-10n and the flow paths 13 constituted with the communicating ports 9, 11, are formed. |
