Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a chemosynthesis oil coolant with high boiling point is used in single liquid phase cooling, then coolant vaporization is avoided, but cooling capability is reduced due to high viscosity
Solution Approach 1:
The patent changes the physical state parameter of the coolant from liquid phase to gas-liquid phase change, enabling the use of low boiling point coolants that provide high cooling capability through vaporization while maintaining system reliability through controlled phase transition
Solution Approach 2:
The patent replaces the mechanical pump-based circulation system with a natural circulation system driven by density differences and pressure gradients, eliminating the need for high-power pumps and reducing energy consumption
2Reliability
If chemosynthesis oil coolant with high viscosity is used, then coolant stability is maintained, but pump driving force must be increased to speed up circulation
Solution Approach 1:
The patent changes the coolant's physical state to utilize phase transition, allowing the use of low-viscosity coolants that naturally circulate without requiring high pump power
Solution Approach 2:
The cooling system utilizes natural circulation driven by density differences and pressure gradients between vaporization and condensation zones, enabling self-service coolant circulation without external pump assistance
3Productivity
If low boiling point coolant is used for gas-liquid phase change cooling, then cooling capability and maintainability are improved, but coolant evaporation and loss increase
Solution Approach 1:
The patent utilizes controlled phase transitions of the coolant between liquid and vapor states, where vaporized coolant is condensed and returned to the liquid phase, creating a closed cycle that prevents coolant loss while maintaining high cooling capability
Solution Approach 2:
The patent creates a sealed environment for the coolant system, preventing evaporated coolant from escaping into the air and maintaining an inert atmosphere that prevents unwanted chemical reactions and coolant loss
4Productivity
If low boiling point coolant is used, then coolant viscosity is reduced and circulation is improved, but coolant tends to evaporate and escape into air
Solution Approach 1:
The patent implements a controlled phase transition system where coolant vaporization is harnessed for cooling and the resulting vapor is condensed back to liquid, preventing uncontrolled evaporation and escape into the air
Solution Approach 2:
The patent employs a sealed system environment that prevents coolant vapor from escaping into the surrounding air, containing the evaporated coolant within the system where it can be condensed and reused
