1. A separated coolant circulation structure for a water-cooled power generator, comprising:
- a cooling circulation channel for a stator bar including a first coolant supply path that is configured to cool heat of a stator bar winding; and
a cooling circulation channel for a connector ring including a second coolant supply path that is configured to cool heat of a connector ring,wherein the first coolant supply path is separated from the second coolant supply path, the first coolant supply path is connected to a first coolant discharge ring, and the second coolant supply path is connected to a second coolant discharge ring to improve cooling efficiency and reduce a pump load.

14. A method of separately cooling a water-cooled power generator, comprising:
-
cooling heat of a stator winding by a cooling circulation channel for the stator winding that includes a first coolant supply path; cooling heat of a connector ring by a cooling circulation channel for the connector ring that includes a second coolant supply path, wherein, the step of cooling the stator winding includes supplying a coolant through the first coolant supply path to the first coolant discharge ring and the step of cooling the connector ring includes supplying the coolant through the second coolant supply path, separated from the first coolant supply path, to a second coolant discharge ring, thereby improving cooling efficiency and reducing a pump load. - View Dependent Claims (15, 16, 17, 18, 19, 20)
