EXHAUST GAS HEAT RECOVERY DEVICE

摘要

An exhaust gas heat recovery device of the present invention recovers heat of an exhaust gas from an internal combustion engine. The exhaust gas heat recovery device includes an exhaust pipe (1) that leads the exhaust gas from an upstream side to a downstream side, a cylindrical shell (2) that covers an outside of the exhaust pipe, and an exhaust gas heat recovery section (4) that is interposed between the exhaust pipe and the cylindrical shell and that performs heat exchange between the exhaust gas and a heat exchange medium. The exhaust gas heat recovery section includes a stacked body (10) that is composed by stacking a plurality of jacket parts (6, 8) each having a heat exchange medium conduit provided thereinside. In the stacked body, the respective heat exchange medium conduits (20) in the plurality of jacket parts are serially connected to each other.
