PROBLEM TO BE SOLVED: To provide a heat exchanger including two partitioned tank spaces and capable of suppressing cost increase due to the shape of packing.SOLUTION: An outer peripheral packing 62 interposed between an outer circumferential end portion 441 of a tank outer shell 44 and a core plate member 40 is a separated component from a partition packing 64 interposed between a tank partition portion 46 and the core plate member 40. Owing to this, the outer peripheral packing 62 is similar in shape to a packing for a heat exchanger in which a tank space is not partitioned. On the other hand, if an integral packing member obtained by integrating the outer peripheral packing 62 with the partition packing 64 is used, the integration makes the shape of the integral packing member complicated. Therefore, component cost of combination of the separately provided outer peripheral packing 62 and partition packing 64 is lower than that of the integral packing member. It is thus possible to suppress cost increase due to the packing shape. |
