Abstract

An exhaust heat recovering device comprising an exhaust heat recovering tool (10) adapted to recover a heat of an exhaust gas of an internal combustion engine for a vehicle and an inflow side pipeline (14) and an exhaust side pipeline (13) adapted to connect the internal combustion engine and the exhaust heat recovering tool, wherein the inflow side pipeline (14) and the exhaust side pipeline (13) are mounted only on a component included in a non-vehicle body vibration system supported on a vehicle body (2) through an elastic body (4, 5, 6).

First claim

The invention claimed is:

1. An exhaust heat recovering device comprising:
an exhaust heat recovering tool adapted to recover a heat of an exhaust gas of an internal combustion engine for a vehicle and
an inflow side pipeline and an exhaust side pipeline adapted to connect the internal combustion engine and the exhaust heat recovering tool, wherein
the inflow side pipeline and the exhaust side pipeline are mounted only on a component included in a non-vehicle body vibration system supported on a vehicle body through an elastic body; and
at least either one of the inflow side pipeline and the exhaust side pipeline is mounted on at least either one of the internal combustion engine or the exhaust passage included in the non-vehicle body vibration system at a position other than both ends thereof.

2. The exhaust heat recovering device according to claim 1 , wherein
the exhaust heat recovering tool is interposed in an exhaust passage on a downstream of an underfloor catalyst.

3. The exhaust heat recovering device according to claim 1 , wherein
as a component included in the non-vehicle body vibration system, at least either one of the internal combustion engine and an exhaust passage through which the exhaust gas flows is included.

4. The exhaust heat recovering device according to claim 3 , wherein
at least either one of the inflow side pipeline and the exhaust side pipeline is mounted on the internal combustion engine and the exhaust passage at positions other than the both ends thereof, and a vibration absorbing unit is included between a mount position on the internal combustion engine and a mount position on the exhaust passage adjacent to the mount position on the internal combustion engine.

5. The exhaust heat recovering device according to claim 1 , wherein
a heat medium take-out port of the inflow side pipeline is connected to an EGR cooler fixed/supported on the internal combustion engine.
