Document Type and Number:

WIPO Patent Application WO/2019/225150

Kind Code:

A1

Abstract:

This exhaust heat recovery device 1 is provided with a heat exchange flow channel 10A (a heat exchange part 10) and a main exhaust flow channel 20A (a bypass part 20) bypassing the heat exchange flow channel 10A, the heat exchange flow channel 10A and the main exhaust flow channel 20A being provided on an exhaust path. An exhaust gas flows from the main exhaust flow channel 20A to the heat exchange flow channel 10A via a gas inlet 11, and flows from the heat exchange flow channel 10A to the main exhaust flow channel 20A via a gas outlet 12. In the heat exchange part 10, heat is exchanged between the exhaust gas and a heat medium. On the main exhaust flow channel 20A inside the bypass part 20, a valve 30 is provided on the downstream side of the gas outlet 11. A return flow channel 17 through which the exhaust gas flows in the reverse direction B1 from the flow direction of the exhaust gas inside the main exhaust flow channel 20A is provided on the furthest downstream side of the heat exchange flow channel 10A.
