To downsize a heat exchanger and to provide a vehicular heat exchange system which can effectively use exhaust heat from a motor.SOLUTION: The heat exchanger is provided in which a first flow passage (second, fourth, and sixth layers) and a third flow passage (first, third, fifth, and seventh layers) are alternately arranged in a stacked direction in a region from a partition wall 56 at one end to a partition wall 55m in the middle, a second flow passage (eighth, tenth, and twelfth layers) and a third flow passage (ninth, eleventh, and thirteenth layers) are alternately arranged in a region from a partition wall 56m in the middle to a partition wall 54 at the other end, and the third flow passage (first, third, fifth, and seventh layers) and the third flow passage (ninth, eleventh, and thirteenth layers) communicate with each other to form a continuous flow passage. The vehicular heat exchange system is also provided that comprises: a first heat exchanger exchanging heat between a first medium for use in cooling of an internal combustion engine and a third medium for use in lubrication of a transmission and/or cooling of a motor; and a second heat exchanger exchanging heat between a second medium for use in cooling of an inverter and the third medium.SELECTED DRAWING: Figure 13

    【課題】熱交換器の小型化を図ること。モータからの排熱を有効利用し得る車両用の熱交換システムを提供すること。【解決手段】一端の隔壁56から途中の隔壁55mまでは積層方向において第1の流路(第2、4、6層)と第3の流路(第1、3、5、7層)とが交互に配置され、途中の隔壁56mから他端の隔壁54までは第2の流路(第8、10、12層)と第3の流路(第9、11、13層)とが交互に配置され、第3の流路(第1、3、5、7層)と第3の流路(第9、11、13層)とが連通して連続した流路を形成している熱交換器。内燃機関の冷却に用いられる第1媒体と、トランスミッションの潤滑および/またはモータの冷却に用いられる第3媒体と、の間の熱交換を行う第1熱交換器と、インバータの冷却に用いられる第2媒体と、前記第3媒体と、の間の熱交換を行う第2熱交換器と、を備える車両用の熱交換システム。【選択図】図13
