EXHAUST HEAT RECOVERY DEVICE STRUCTURE

摘要

An exhaust heat recovery device structure comprises: an exhaust pipe which is extended in the longitudinal direction of a vehicle and allows the gas generated in an internal combustion engine to be discharged thereto; a catalyst converter which is connected to the exhaust pipe; an exhaust heat recovery device which is formed behind the catalyst converter in the rear part of the vehicle or on the inner side of a floor tunnel formed in the bottom part of the vehicle, allows a cooling water pipe for cooling the internal combustion engine to be connected to one side thereof in the width direction of the vehicle, and performs heat exchange between the cooling water and the gas; and a curved connection pipe which connects the catalyst converter and the exhaust heat recovery device to each other on the inner side of the floor tunnel and is curved from the rear part to the front part of the vehicle in the width direction of the vehicle when seeing at a plane. Therefore, the present invention secures a work space without an increase in the cross section of the floor tunnel.
