(EN) Exhaust heat recovery device
Abrégé
(EN)

An exhaust heat recovery device includes: a first pipe through which exhaust gas from an engine flows; a second pipe that communicates with the first pipe and bypasses the first pipe; a heat recovery unit that is disposed at an interior of the second pipe, and that exchanges heat between the exhaust gas and cooling water that circulates at an interior of the heat recovery unit, and that recovers heat of the exhaust gas; and a heat transfer suppressing mechanism that is provided at a portion connecting the first pipe with the second pipe, and that suppresses transfer of heat from the first pipe to the second pipe.
