Exhaust-gas heat recovery appliance
First Claim
1. An exhaust-gas heat recovery appliance comprising a heat exchanger line and a bypass line installed at a position on a motor vehicle, the heat exchanger line and the bypass line connected at their upstream ends to a first exhaust-line fork and downstream at their downstream ends to a second exhaust-line fork, a heat exchanger being arranged in the region of the heat-exchanger line, an “
- S”
shaped line element in the heat-exchanger line located upstream of an inlet of the second exhaust-line fork, and at least one valve device adapted to influence the mass flow of exhaust gas being provided in the heat-exchanger line and the bypass line, wherein, in the installed position the heat-exchanger line and the bypass line run parallel to one another a short distance apart in plan view, and when viewed from the side at least the heat-exchanger line has a slope in a direction of flow of the exhaust gas and the “
S”
shaped line element has a slope steeper than the slope of the heat-exchanger line to act as a barrier to return flow.

Abstract
An exhaust-gas heat recovery appliance having a heat-exchanger line and a bypass line and a heat exchanger being arranged in the region of the heat-exchanger line. At least one valve device, for the purpose of influencing the mass flow of exhaust gas, is provided in the heat-exchanger line and the bypass line. Further, at least the heat-exchanger line has a slope in the direction of flow of the exhaust gas in the installed position.
