摘要： Regarding an engine exhaust gas heat exchanger that allows exhaust gas to collide with a coolant passage through apertures, a configuration that can improve efficiency of heat exchange is provided. The engine exhaust gas heat exchanger 1 is provided with multiple stages of unit exhaust gas passages 3a, 3b, 3c that are configured with a first exhaust gas passage A in which a plane facing an inlet is blocked and that has a plurality of apertures 30 in a circumferential direction and in a flow direction, and a second exhaust gas passage B that has a dividing wall facing the apertures 30 and also serving as the coolant passage 20 and an outlet that also serves as an inlet of the first exhaust gas passage A of a next stage or an outlet 26 of the engine exhaust gas heat exchanger 1.
