Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If liquid cooling technology is adopted for high power density servers, then heat dissipation efficiency is improved, but risk of liquid leakage damaging hardware increases
Solution Approach 1:
The server interior space is segmented into liquid-cooled regions and air-cooled regions using partition structures. The partition structures divide the casing into separate zones, allowing liquid cooling to be applied only to specific high-power components while isolating it from other hardware, thus enabling efficient heat dissipation while preventing liquid leakage from damaging unrelated components.
Solution Approach 2:
Partition structures serve as intermediary barriers between the liquid cooling system and other hardware components. These partitions act as protective intermediaries that contain potential liquid leakage within designated zones, preventing direct contact between cooling liquid and sensitive electronics, thereby maintaining hardware safety while preserving cooling effectiveness.
2Reliability
If conventional air cooling is used, then hardware safety is maintained, but heat dissipation efficiency is insufficient for high power density servers
Solution Approach 1:
The cooling system is segmented into multiple zones with different cooling methods. High-power density components are placed in liquid-cooled zones for efficient heat removal, while other components remain in air-cooled zones maintained at safe temperatures. This spatial segmentation allows the system to achieve overall heat dissipation efficiency while maintaining hardware safety through controlled liquid containment.
Solution Approach 2:
Different cooling qualities are applied to different regions of the server. Liquid cooling with high heat dissipation capability is applied locally to high-power components, while air cooling is used for other areas. This localized approach optimizes heat dissipation efficiency where needed while maintaining hardware safety across the entire system.
3Temperature
If liquid cooling module is placed close to functional modules for efficient cooling, then heat dissipation is improved, but risk of liquid leakage to other modules increases
Solution Approach 1:
The server interior is segmented into isolated zones using partition structures. The liquid cooling module is placed in a dedicated zone adjacent to functional modules for efficient cooling, but the partition structures create physical barriers that prevent liquid leakage from affecting other modules. This segmentation enables close proximity for heat dissipation while containing potential harmful effects.
Solution Approach 2:
Partition structures with blocking walls and guiding walls form flexible boundary definitions that contain liquid within specific zones. These partition structures act as protective barriers that can guide liquid flow along predetermined paths to drip holes, preventing uncontrolled spread of leaked liquid to other modules while maintaining efficient cooling proximity.
