Abstract: A heat exchanger causes heat exchange between water and a refrigerant. The heat exchanger includes a first flow path through which the water flows, and a second flow path through which the refrigerant flows. A fragile portion is formed by any one of members forming the first flow path other than a partition wall partitioning the first flow path and the second flow path or any one of joining portions where members forming the first flow path are joined to each other. The fragile portion has a lower strength than the other members forming the first flow path.

Abstract: In a heat exchanger, a fluid flows in a first direction between a first opening and a second opening. The heat exchanger includes a member forming N flow path regions arranged adjacent to each other along the first direction between the first opening and the second opening. N is an integer of 2 or more. Each of the N flow path regions includes a flow path through which the fluid flows. A first flow path region and an N-th flow path region are different from each other in number and cross-sectional area of the flow paths. The first flow path region is one of the N flow path regions located to be closest to the first opening in the first direction. The N-th flow path region is one of the N flow path regions located to be N-th closest to the first opening in the first direction.
