Claim Text:
1. A Rankine cycle, comprising: an waste-heat recovery device that is configured to exchange heat between cooling water coming out from an engine and exhaust gas exhausted from the engine; a heat exchanger including an evaporator through which the cooling water coming out from the engine flows to recover waste-heat of the engine to refrigerant, and a superheater through which the cooling water coming out from the waste-heat recovery device flows to recover the waste-heat of the engine to the refrigerant; an expander that is configured to generate power using the refrigerant coming out from the heat exchanger; a condenser that is configured to condense the refrigerant coming out from the expander; and a refrigerant pump that is configured to supply the refrigerant coming out from the condenser to the heat exchanger by being driven by the expander; wherein the cooling water coming out from the superheater is returned to the engine after being joined with the cooling water coming out from the evaporator.
