An integrated exhaust heat recovery device positioned in an exhaust gas channel includes: a positioning section that comprises a tubular section extending in a downward-flow direction of exhaust gas, and has an exhaust gas purification device positioned therein; a heat exchange section positioned on a downstream side of the positioning section and having a heat exchanger; and an exhaust gas control unit for introducing exhaust gas, which flows from the positioning section, to the heat exchange section. The heat exchanger includes: a plurality of plates positioned so as to overlap in the downward-flow direction; an intake section for causing fluid to flow into heat exchange channels inside the plurality of plates from an intake port that opens laterally; and a discharge section for causing fluid to exit from the heat exchange channels through a discharge port that opens laterally.

Integrated exhaust heat recovery device

An exhaust heat recovery device comprises an exhaust pipe, a shell member, a heat exchange portion, an inflow portion, a valve, a driving portion that generates a driving force for driving the valve, and a transmitting portion that transmits the driving force generated by the driving portion to the valve. The driving portion comprises an expansion portion that expands when an external electrical signal is inputted thereto, and a linearly moving portion that extends according to expansion of the expansion portion.

Exhaust heat recovery device including engagement portion configured to rotate valve

A valve device opens/closes an opening that is located at an end portion of a flow path and whose shape is a point symmetrical or substantially point symmetrical planar figure. The valve device includes a lid portion closing the opening and an arm portion rotating the lid portion about an axis to open/close the opening. A straight line passing through the center of the opening and orthogonal to the opening is taken as a center line. The axis is a straight line intersecting the flow path without intersecting the center line. When closing the opening, the arm portion rotates the lid portion toward the center line, and when opening the opening, the arm portion rotates the lid portion to the opposite side of the center line.
