摘要： An exhaust heat recovery device with which a coolant medium in a heat exchanger can be prevented from reaching high temperatures is provided. An exhaust heat recovery system 10 is provided with an heat exchanger 18 that performs heat exchange between exhaust gas and a coolant medium; and a natural convection water pipe 56 whose one end is connected to an upper portion in the direction of gravity of an engine coolant water pipe 42 in the heat exchanger 18 and whose other end is connected to a lower portion in the direction of gravity of the engine coolant water pipe 42, and whose intermediate portion is positioned at the outer side of the heat exchanger 18.
