Engineering Contradiction Analysis
1Extent of automation
If manual adjustment of coolant flow rate is used, then the system can operate with fixed flow rate, but the flow rate cannot be automatically adjusted when server quantity changes
Solution Approach 1:
The system uses detectors to monitor the communication states of liquid cooling units and feeds this information back to the controller, which automatically adjusts the coolant flow rate based on the detected number of active units. This closed-loop feedback mechanism enables automatic adaptation to changing server quantities without manual intervention.
Solution Approach 2:
The liquid cooling system performs self-adjustment by automatically detecting the number of connected liquid cooling units through communication state detection and autonomously modifying the coolant flow rate accordingly. The system serves itself by eliminating the need for manual flow rate adjustment when server quantity changes.
2Ease of operation
If manual flow rate adjustment is required, then the system structure remains simple, but operational convenience deteriorates when server quantity changes
Solution Approach 1:
Detectors continuously monitor the communication states of liquid cooling units and provide feedback to the controller, enabling automatic flow rate adjustment based on the number of active servers. This feedback mechanism significantly improves operational convenience by eliminating manual adjustment requirements.
Solution Approach 2:
The system replaces manual mechanical adjustment with an automated control system that uses communication state detection and electronic control to adjust coolant flow rate. This substitution of mechanical manual operation with automated electronic control enhances ease of operation.
3Productivity
If fixed flow rate is used, then the system is easy to control, but heat exchange efficiency cannot be optimized for varying server quantities
Solution Approach 1:
The coolant flow rate is transformed from a fixed static parameter to a dynamic adjustable parameter that automatically adapts to the number of active liquid cooling units. The controller dynamically modifies flow rate based on real-time detection of communication states, optimizing heat exchange efficiency for varying server quantities.
Solution Approach 2:
The system automatically changes the coolant flow rate parameter based on the detected number of active liquid cooling units. By varying the flow rate parameter dynamically rather than maintaining a fixed value, the system optimizes heat exchange efficiency according to actual server workload and quantity.
