EXHAUST HEAT RECOVERY DEVICE STRUCTURE

PROBLEM TO BE SOLVED: To provide an exhaust heat recovery device structure that can secure a work space without expanding a cross section of a floor tunnel in the structure in which an exhaust heat recovery device is disposed in the floor tunnel.SOLUTION: An exhaust heat recovery device structure includes: an exhaust pipe 10 that is extended in a vehicle longitudinal direction and from which gas generated in an internal combustion engine is discharged; a catalytic converter 12 connected to the exhaust pipe 10; an exhaust heat recovery device 16 that is disposed on a vehicle rear side from the catalytic converter 12 and on an inner side of a floor tunnel formed on a vehicle floor portion and in which water piping 30 for cooling water for cooling the internal combustion engine is connected to one side in the vehicle width direction to exchange heat between the cooling water and gas; and a connection pipe 14 that interconnects the catalytic converter 12 and the exhaust heat recovery device 16 on the inner side of the floor tunnel and in which the vehicle rear side is bent or curved to one side in the vehicle width direction relative to the vehicle front side in plane view.SELECTED DRAWING: Figure 1 【課題】排熱回収器がフロアトンネルに配設された構造において、フロアトンネルの断面を広げることなく、作業スペースを確保することができる排熱回収器構造を得る。【解決手段】排熱回収器構造は、車両前後方向に延在され、内燃機関で発生したガスが排出される排気管１０と、排気管１０に接続された触媒コンバータ１２と、触媒コンバータ１２よりも車両後方側且つ車両床部に形成されたフロアトンネルの内側に配設されると共に、内燃機関を冷却する冷却水の水配管３０が車両幅方向の一方側に接続され、冷却水とガスとの間で熱交換を行う排熱回収器１６と、フロアトンネルの内側で触媒コンバータ１２と排熱回収器１６とを連結すると共に、平面視で車両後方側が車両前方側に対して車両幅方向の一方側に屈曲又は湾曲した連結管１４と、を有する。【選択図】図１
