Separated Coolant Circulation for Water-Cooled Generator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-capacity water-cooled power generators face decreased cooling efficiency and increased pump load due to prolonged coolant circulation paths, which are exacerbated by simultaneous cooling of stator bars and connector rings using the same coolant lines.
Innovation Solution
A separated coolant circulation structure is implemented, where the connector ring cooling circulation unit and stator bar cooling circulation unit have distinct coolant supply paths, with annular coolant supply and discharge rings and coupling hoses to efficiently direct coolant flow, reducing the length of each cooling path and pump load.

Engineering Contradiction Analysis
1Reliability
If the coolant circulation path is prolonged to cool both stator bars and connector rings using the same coolant lines, then both components can be cooled, but the cooling efficiency decreases and pump load increases
Solution Approach 1:
The patent divides the coolant circulation system into separate circulation paths: one for stator bars and another for connector rings. This segmentation allows each component to be cooled independently with optimized coolant flow paths, preventing the cooling efficiency degradation that would result from a single prolonged circulation path cooling both components sequentially.
