Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If liquid cooling system is employed to cool high power consumption servers, then cooling effect is improved, but coolant leakage risk increases due to damaged pipeline walls
Solution Approach 1:
The patent applies preliminary action by continuously monitoring the cooling system through flow rate sensors at the inlet and outlet, detecting potential coolant leakage before it causes serious damage. The system proactively identifies abnormal flow rate differences and triggers warnings or shutdowns in advance, preventing catastrophic failures.
2Measurement precision
If flow rate sensors are installed at inlet and outlet to detect coolant leakage, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
The patent applies the extraction principle by isolating the detection function into separate flow rate sensors positioned at specific locations (inlet and outlet). This allows the detection system to be independently installed and maintained without disrupting the entire cooling system, reducing overall complexity while maintaining high measurement precision.
3Loss of time
If continuous monitoring of flow rate difference is implemented, then response time to coolant leakage is reduced, but energy consumption increases
Solution Approach 1:
The patent applies periodic action by implementing continuous monitoring through flow rate sensors that operate at appropriate intervals to detect flow rate differences. The system monitors continuously but can adjust monitoring intensity based on detected anomalies, triggering more frequent checks only when needed, thus reducing unnecessary energy consumption while maintaining rapid response capability.

AI summary
A detection method for a cooling system includes detecting first flow rate difference information of the cooling system of a server device through a flow rate detection device, and determining status information of the cooling system according to the first flow rate difference information. The first flow rate difference information indicates a difference between an inlet flow rate and an outlet flow rate of the cooling system. The status information indicates whether the cooling system has a coolant leakage.
