Document Type and Number:
Japanese Patent JP7221853
Kind Code:
B2
Abstract:
To provide a technique for suppressing unnecessary heat exchange.SOLUTION: An exhaust heat recovery device includes a pipe part constructing a first flow path as a flow path where heat exchange between exhaust gas and a heat exchanger is not performed, and a second flow path as a flow path where the heat exchange is performed, and a valve constructed to be movable to a first position and to a second position, the first position being a position for blocking a first outlet to further increase the flow amount of exhaust gas to the second flow path than before blocking it, the second position being a position for opening the first outlet to further reduce the flow amount of the exhaust gas to the second flow path than before opening it. The valve when being at the second position guides at least part of the exhaust gas from the first outlet to a second outlet.SELECTED DRAWING: Figure 3
