Definitions

  • the present invention relates to an exhaust heat recovery device, which is applied to, for example, an exhaust system, etc. of an internal combustion engine.
  • an exhaust heat recovery device which performs heat exchange between exhaust gas of an internal combustion engine and a heat exchange medium, such as cooling water, so as to recover the exhaust heat.
  • the exhaust heat recovery device is provided with a diversion valve at an outlet of an exhaust pipe, which is capable of opening and closing the outlet.
  • the exhaust heat recovery device is provided with a heat exchange path that extends from a branch port provided inside of the exhaust pipe through a heat exchanger part, to an exhaust port provided outside of the exhaust pipe (see, Patent Document 1 below).
  • Patent Document 1 Japanese Unexamined Patent Application Publication No. 2009-114995
  • An exhaust heat recovery device in one aspect of the present invention includes: 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.
  • the shell member includes 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; the exhaust port is positioned between the outlet and the intersecting plane in the axial direction.
  • the opening and closing unit for example, diversion valve
  • an amount of the exhaust gas flowing in the heat exchange part can be further reduced. The reason can be assumed as below.
  • the shell member comprises the intersecting plane intersecting the virtual ray that extends from an end part of the outlet on a side of the exhaust port, the end part serving as the starting point, and the virtual ray being inclined outwardly at the angle of 7° with respect to the axial direction of the exhaust pipe, and the intersecting plane forms the 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 of the exhaust pipe and therefore, the exhaust port is covered with the aforementioned swirl. For this reason, a phenomenon of drawing exhaust gas from the exhaust port by the flow of the exhaust gas in the exhaust pipe is less likely to occur. Consequently, an amount of the exhaust gas flowing in a flow path from the branch port through the heat exchange part to the exhaust port is further reduced. This further inhibits unnecessary heat exchange.
  • the above-described exhaust heat recovery device may comprise, for example, a partition plate that is provided in the exhaust port and that forms a passage that guides the exhaust gas to the downstream side.
  • a partition plate that is provided in the exhaust port and that forms a passage that guides the exhaust gas to the downstream side.
  • an outlet of the passage formed by the partition plate is closer to the aforementioned swirl of the exhaust gas and therefore, the outlet is more likely to be covered with the swirl of the exhaust gas. Consequently, unnecessary heat exchange can be further inhibited.

  • FIG. 2 is a cross sectional view taken along a line II-II in FIG. 1 .
