Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a coolant supply assembly with multiple filtration devices is used to remove three-phase impurities, then the reliability of the immersion liquid cooling system is improved, but the device complexity increases
Solution Approach 1:
The patent combines pre-filter, main filter, and desiccant unit into a single integrated coolant supply assembly. The housing unifies multiple filtration functions, and the mounting portions on the housing allow compact arrangement of all components in one location, reducing system complexity while maintaining reliable three-phase impurity removal
Solution Approach 2:
The coolant supply assembly performs multiple functions within a single device: particle filtration through pre-filter and main filter, water removal through desiccant unit, and system pressure regulation through the integrated pump. This multi-functionality eliminates the need for separate components for each function, improving reliability without proportionally increasing complexity
2Adaptability or versatility
If the desiccant unit uses fixed molecular sieves, then the structure is simple, but the adaptability to different liquid levels and operating conditions is reduced
Solution Approach 1:
The desiccant unit employs adjustable molecular sieves that can be vertically positioned at different heights within the housing. This dynamic adjustment capability allows the molecular sieves to adapt to varying liquid levels and operating conditions, optimizing water removal efficiency while maintaining a relatively simple overall structure
Solution Approach 2:
The molecular sieves are pre-positioned at adjustable heights within the desiccant unit during manufacturing. This preliminary positioning allows the system to be pre-configured for different operating scenarios, enabling quick adaptation to various liquid levels and conditions without requiring complex real-time adjustment mechanisms

Function Achieved in This Case
The assembly reliably removes three-phase impurities, enhancing the efficiency and service life of immersion liquid cooling systems by reducing wear and preventing molecular sieve failure, while optimizing operation through integrated sensors and valves.
Implementation Method 1
a gas phase filter molecular sieve, and a liquid phase filter molecular sieve. The upper cover, the lower cover and the shell may form an internal volume, the gas phase filter molecular sieve being disposed in an upper portion of the internal volume, and the liquid phase filter molecular sieve being disposed in a lower portion of the internal volume
Implementation Method 2
The desiccant unit may further include a spring and a regulator, the spring and the regulator being configured to cooperate to automatically adjust a vertical position of the gas phase filter molecular sieve and the liquid phase filter molecular sieve
