Abstract
In an exhaust heat recovery structure, a heat exchange portion (a tubular part) is configured such that a height of a lower inner surface is lowered from an inlet toward an outlet. Hence, when exhaust gas is condensed and condensed water is thereby generated inside the heat exchange portion (the tubular part), the condensed water flows from the inlet side toward the outlet side where the lower inner surface is lowered, and is then discharged to a piping part. Accordingly, the condensed water is unlikely to be collected inside the heat exchange portion.
