Abstract
A separated coolant circulation structure for a water-cooled power generator includes a cooling circulation channel for a stator bar to cool heat of a stator bar winding, and a cooling circulation channel for a connector ring to heat of a connector ring, wherein the cooling circulation channel for the stator bar and the cooling circulation channel for the connector ring form separate coolant supply paths to improve cooling efficiency and reduce a pump load.
