Zusammenfassung:To provide a heat exchanger which inhibits a temperature of a fluid from increasing locally to improve heat exchange efficiency.SOLUTION: A heat exchanger 100 includes second passages 22, each of which is formed between adjacent tubes 50 and in which a coolant (a second fluid) circulates. Each tube 50 has: an oblique guide 71 which protrudes to the second passages 22 and extends so as to come closer to an upstream side part 63 in a direction away from a second fluid inlet 25; and vertical guides 73 to 76 protruding to the second passage 22 and extending in an X axis direction (a passage direction). The pair of oblique guides 71, which face each other and protrude from the adjacent tubes 50, forms gaps at the upstream side of the vertical guides 73 to 76 at the second passage 22.SELECTED DRAWING: Figure 3 【課題】流体の温度が局所的に上昇することを抑えて、熱交換効率を高められる熱交換器を提供すること。【解決手段】熱交換器100は、隣り合うチューブ50の間に形成されて冷却水(第2流体)が流通する第2流路22を備える。チューブ50は、第2流路22に突出して第2流体入口25から離れるほど上流辺部63に近づくように延在する斜めガイド71と、第2流路22に突出してX軸方向(流路方向)に延在する縦ガイド73〜76と、を有する。隣り合うチューブ50から互いに対向して突出する対の斜めガイド71は、第2流路22において縦ガイド73〜76の上流側に間隙を形成する構成とした。【選択図】図3
