To provide a heat exchanger which can suppress the lowering of heat exchange performance within a range in which a first fluid flows into and out of each stage of a flow passage.SOLUTION: In a heat exchange part 113, outer fins 200 are arranged in a clearance 105 between one tube 100 and another tube 100 in a range except a range including a cup part 110, and the heat exchange part exchanges heat between cooling water flowing through flow passages 103 of a plurality of the tubes 100 and supercharged air flowing through the clearance 105. The cup part 110 has a heat transmission promotion part 201 arranged in a range corresponding to the cup part 110 of the clearance 105, and exchanges heat between the cooling water flowing through the flow passages 103 of the plurality of the tubes 100 and the supercharged air flowing through the range corresponding to the cup part 110 of the clearance 105 via the heat transmission promotion part 201. By this constitution, even if the supercharged air flows into the range including the cup part 110, heat exchange between the cooling water and the supercharged air becomes possible via the heat transmission promotion part 201.SELECTED DRAWING: Figure 2 【課題】第１流体が流路の各段に流出入する範囲における熱交換性能の低下を抑制することができる熱交換器を提供する。【解決手段】熱交換部１１３は、カップ部１１０を含む範囲を除いた範囲において、一方のチューブ１００と他方のチューブ１００との隙間１０５にアウターフィン２００が設けられ、複数のチューブ１００の流路１０３に流れる冷却水と、隙間１０５に流れる過給気と、の熱交換を行う。カップ部１１０は、隙間１０５のうち当該カップ部１１０に対応する範囲に設けられた伝熱促進部２０１を有し、伝熱促進部２０１を介して、複数のチューブ１００の流路１０３に流れる冷却水と、隙間１０５のうち当該カップ部１１０に対応する範囲に流れる過給気と、の熱交換を行う。これにより、カップ部１１０を含む範囲に過給気が流入しても、伝熱促進部２０１を介して冷却水と過給気との熱交換が可能になる。【選択図】図２
