Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If dual-phase heat absorbing fluorine coolants are used in the immersion heat dissipation system, then heat exchange efficiency is improved, but environmental pollution increases due to non-zero global warming potential
Solution Approach 1:
The patent changes the physical state parameter of the coolant from dual-phase (liquid-gas mixture) to single-phase (liquid only), and selects coolant material with zero GWP value, thereby maintaining heat exchange efficiency through single-phase heat transfer while eliminating environmental pollution associated with fluorine-based dual-phase coolants
Solution Approach 2:
The patent employs single-phase coolants with zero GWP that can be used without stringent environmental containment requirements, effectively replacing expensive and environmentally harmful dual-phase fluorine coolants with simpler, cleaner alternatives that do not require high airtightness infrastructure
2Productivity
If dual-phase coolants are used to achieve good heat exchange efficiency, then heat dissipation performance is improved, but device costs increase due to high airtightness requirements
Solution Approach 1:
The patent changes the operational parameters by using single-phase coolant circulation instead of dual-phase evaporation-condensation cycles, which eliminates the need for high airtightness sealed enclosures and associated costly infrastructure, thereby reducing device costs while maintaining effective heat exchange
Solution Approach 2:
The patent extracts and removes the requirement for high airtightness sealed environments from the heat dissipation system by transitioning to single-phase coolant operation, thereby eliminating the need for expensive airtightness maintenance infrastructure and associated device costs
3Reliability
If non-conductive synthetic oil with high flash point is used, then safety requirements are met, but thermal conductivity efficiency is limited
Solution Approach 1:
The patent changes the thermal parameter optimization approach by focusing on circulation dynamics and heat exchange system design rather than relying solely on high flash point materials, thereby achieving both safety compliance and improved thermal conductivity efficiency through enhanced single-phase liquid circulation and heat transfer mechanisms
4Ease of manufacture
If single-phase coolant is used, then airtightness requirements are reduced, but heat dissipation efficiency may be limited compared to dual-phase systems
Solution Approach 1:
The patent applies dynamic circulation mechanisms with pumps and circulation modules to enhance single-phase coolant flow velocity and heat transfer coefficients, thereby compensating for the lower heat dissipation efficiency of single-phase systems compared to dual-phase systems while maintaining reduced airtightness requirements
Solution Approach 2:
The patent implements preliminary heating and pre-cooling sections in the circulation path to optimize the temperature differential and heat transfer efficiency of the single-phase coolant before it contacts the heat-generating components, thereby enhancing overall heat dissipation efficiency without requiring high airtightness
