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.

Claim (Index 1):
An exhaust heat recovery device comprising a heat exchange portion, an exhaust branch portion, and an exhaust distribution portion,\n 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 honeycomb body comprises partition walls made of ceramic as a main component, and a plurality of cells extending from the first end face to the second end face and serving as a flow path of exhaust gas are defined and formed by the partition walls, the casing comprises a cylindrical member arranged so as to be fitted to an outer circumferential surface of the honeycomb body, and a casing body arranged outside the cylindrical member, forming a path of a heat exchange medium for recovering exhaust heat by heat exchange with the exhaust gas, and comprising a heat exchange medium introduction port into which the heat exchange medium is introduced and a heat exchange medium discharge port from which the heat exchange medium is discharged, the exhaust branch portion has a branch path that branches the path of the 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.
