Summary:To improve strength of a heat exchanger.SOLUTION: In an oil cooler 1, a boss part 21 and a boss part 24 formed so as to surround a through hole 13 and an oil passage hole 11 are brazed. The oil cooler 1 can secure a large brazing area due to the boss parts 21, 24 having a large outline and a large area, can eliminate a space between first and second core plates 5, 6 adjacent in a lamination direction in an inter-plate cooling water flow path 8, and can improve strength around the oil passage hole 11 and the through hole 13, which are fluid ports.SELECTED DRAWING: Figure 3 【課題】熱交換器の強度を向上させる。【解決手段】オイルクーラ１は、貫通穴１３とオイル通過穴１１を囲んで形成されたボス部２１とボス部２４をろう付けするようにしている。オイルクーラ１は、輪郭が大きく面積の大きなボス部２１，２４により大きなろう付け面積を確保できるとともに、プレート間冷却水流路８内において積層方向に隣接する第１、第２コアプレート５，６の間の空間をなくすことができ、流体ポートであるオイル通過穴１１及び貫通穴１３の周囲の強度を向上させることができる。【選択図】図３
