Exhaust Heat Recovery Device

Abstract

An exhaust heat recovery device according to one aspect of the present invention comprises an exhaust pipe, a branch port, a heat exchange part, an exhaust port, an opening and closing unit, and a shell member. The shell member comprises an intersecting plane intersecting a virtual ray that extends from an end part of an outlet of the exhaust pipe on a side of the exhaust port, the end part serving as a starting point, and the virtual ray being inclined outwardly at an angle of 7° with respect to an axial direction of the exhaust pipe, and the intersecting plane forms an angle of 90° to 97° with respect to the virtual ray. The exhaust port is positioned between the outlet and the intersecting plane in the axial direction.

1 . An exhaust heat recovery device comprising:
 an exhaust pipe that guides exhaust gas from an upstream side to a downstream side;   a branch port for the exhaust gas, provided inside of the exhaust pipe;   a heat exchange part that performs heat exchange between the exhaust gas branched from the branch port and a heat exchange medium;   an exhaust port that discharges the exhaust gas, which has passed through the heat exchange part, to outside of the exhaust pipe;   an opening and closing unit that opens and closes an outlet of the exhaust pipe; and   a shell member that guides the exhaust gas discharged from the outlet and the exhaust port, to the downstream side,   wherein the shell member comprises an intersecting plane intersecting a virtual ray that extends from an end part of the outlet on a side of the exhaust port, the end part serving as a starting point, and the virtual ray being inclined outwardly at an angle of 7° with respect to an axial direction of the exhaust pipe, and the intersecting plane forms an angle of 90° to 97° with respect to the virtual ray, and   wherein the exhaust port is positioned between the outlet and the intersecting plane in the axial direction.   
     
     
         2 . The exhaust heat recovery device according to  claim 1 , further comprising a partition plate provided in the exhaust port and forming a passage that guides the exhaust gas to the downstream side.
