Exhaust heat recovery apparatus

An exhaust heat recovery apparatus for a vehicle that includes an engine and an engine coolant circuit through which an engine coolant for cooling the engine-flows, the exhaust heat recovery apparatus comprising:

• a duct part through which an exhaust gas generated from the engine flows;
• a heated fluid circuit through which a heated fluid to be heated by heat of the exhaust gas flows;
• an evaporator including a plurality of tubes through which an operation medium flows and disposed in the duct part, the evaporator evaporating the operation medium by the heat of the exhaust gas;
• and
• a condenser defining an operation medium circuit through which the operation medium flows, with the evaporator, such that the operation medium circulates through the evaporator and the condenser, the condenser disposed in a passage of the heated fluid circuit, the condenser condensing the operation medium therein by radiating the heat to the heated fluid of the heated fluid circuit, wherein
• the heated fluid circuit is separate from the engine coolant circuit,
• the evaporator further includes a fin disposed between the tubes and joined to the tubes, and
• the fin is provided with an operation force reducing portion that is capable of reducing an operation force applied to the fin caused by a thermal expansion difference between the tubes.
