Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual flow regulation is used in liquid cooling cabinets, then the system structure remains simple, but the flow regulation precision is insufficient leading to imbalances
Solution Approach 1:
The patent implements automatic feedback control by equipping each liquid cooling cabinet with pressure difference detection apparatus that continuously monitors coolant flow conditions. The detected pressure difference signals are fed back to flow regulation apparatus (electromagnetic valves or variable frequency pumps) which automatically adjust coolant flow rates, replacing manual regulation and achieving precise, dynamic flow control without requiring complex manual intervention systems
Solution Approach 2:
The system enables self-service flow regulation where each liquid cooling cabinet independently monitors its own pressure difference and automatically adjusts its coolant flow through integrated detection and control components. This decentralized self-regulation mechanism eliminates the need for centralized manual control while maintaining simple overall system structure through autonomous cabinet-level decision making
2Adaptability or versatility
If multiple liquid cooling cabinets are connected in parallel, then the system can serve multiple electronic devices, but flow imbalances occur due to different power requirements
Solution Approach 1:
The patent applies local quality control by equipping each liquid cooling cabinet with independent pressure difference detection and flow regulation apparatus. Each cabinet independently monitors its local pressure difference conditions and adjusts its coolant flow rate according to its specific power requirements and heat dissipation needs, enabling tailored flow control for different electronic devices while maintaining overall system stability through decentralized adaptation
