Abstract:
An exhaust heat recovery device according to one aspect of the present disclosure includes a main flow path, a secondary flow path, a plurality of heat exchangers, and a communication portion. Exhaust gas flows in the main flow path. The secondary flow path is a flow path branched from the main flow path, and at least a portion of the exhaust gas flows in the secondary flow path. The plurality of heat exchangers are arranged in the secondary flow path. The communication portion communicates with the plurality of heat exchangers and constitutes a portion of the secondary flow path. The communication portion is provided with an exhaust gas outlet which is an outlet for exhaust gas used for exhaust gas recirculation.

Claim (Index 7):
The exhaust heat recovery device according to  claim 3 , wherein among the plurality of heat exchangers, in the heat exchanger located on an upstream side in a flow direction of the exhaust gas in the main flow path, the heat exchange capacity is set to be higher than that of the heat exchanger located on a downstream side in the flow direction of the exhaust gas in the main flow path.
