HEAT EXCHANGER

To provide a heat exchanger capable of improving mountability while enabling mounting to a desired mounted object.SOLUTION: A heat exchanger 10 includes a bracket 50 joined to an outer face 220 of an outermost shell plate member 22 in a plate lamination direction Z. The bracket 50 has a joining portion 51 joined to the outer face 220 of the outermost shell plate member 22, and fixing portions 52a-52d disposed separately from the outer face 220 of the outermost shell plate member in the plate lamination direction Z. On the outer face 220 of the outermost shell plate member 22, the fixing portions 52a-52d are disposed on a part that is capable of being fixed to a vehicle body and avoids a compression force application portion on the outer surface 220 of the outermost shell plate member 22, when the part to which the compression force is applied in joining a plurality of plate members 21 is the compressor force application portion.SELECTED DRAWING: Figure 1 【課題】所望の取付対象への取り付けを可能としながらも、搭載性を向上させることが可能な熱交換器を提供する。【解決手段】熱交換器１０は、プレート積層方向Ｚにおける最外殻プレート部材２２の外面２２０に接合されるブラケット５０を備える。ブラケット５０は、最外殻プレート部材２２の外面２２０に接合される接合部５１と、最外殻プレート部材の外面２２０からプレート積層方向Ｚに離間して配置される固定部５２ａ〜５２ｄとを有する。最外殻プレート部材２２の外面２２０において、複数のプレート部材２１を接合する際に圧縮力が付与される部分を圧縮力付与部とするとき、固定部５２ａ〜５２ｄは、車両ボディへの固定が可能な部分であり、最外殻プレート部材２２の外面２２０において圧縮力付与部を避けた部分に配置されている。【選択図】図１
