PROBLEM TO BE SOLVED: To solve the following problem: when integral brazing is performed in furnace while a joint block is attached to a leading end of a flow path structure, an empty weight of the joint block acts on the flow path structure, and the flow path structure is tilted from a regular joint position toward a head tank.SOLUTION: A flow path structure having two refrigerant flow paths for allowing a refrigerant to flow in/out of an air heat exchange part includes: a head tank 8; and a flow path structure 1 to be brazed to a side plate 15. In tentative fastening before integral brazing, a plurality of first fastening claws 71 which are bendable in a bent axis direction parallel to a core surface 29 of a laminate heat exchanger, and a second fastening claw 72 which is bendable in a bent axis direction vertical to the core surface 29 are provided in the flow path structure 1. Accordingly, during the integral brazing, the flow path structure 1 is prevented from tilting from the regular joint position toward a head tank 8. |
