Abstract
An exhaust heat recovery device including a heat exchange portion, an exhaust branch portion, and an exhaust distribution portion, wherein the heat exchange portion comprises a pillar-shaped honeycomb body having a first end face and a second end face, and a casing accommodating the honeycomb body, the exhaust branch portion has a branch path that branches a path of exhaust gas flowing into the honeycomb body into a central portion and an outer circumferential portion in a cross-section orthogonal to an axial direction of the honeycomb body, and the exhaust distribution portion has an exhaust distribution mechanism that adjusts a heat recovery amount by changing an airflow resistance of the path of the exhaust gas in the central portion of the honeycomb body and varying the exhaust amount passing through the path of the exhaust gas in the outer circumferential portion of the honeycomb body.
