Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If capillary structures in the heat transfer plate and heat pipe are kept independent (not connected), then each structure can maintain its own capillary force, but the return efficiency of vaporized working fluid decreases
Solution Approach 1:
The patent connects the capillary structures of the heat transfer plate and heat pipe through a communication channel, merging them into a unified capillary network. This allows the capillary forces to work cooperatively, improving the return efficiency of vaporized working fluid while maintaining reliable capillary action throughout the system.
Solution Approach 2:
The patent introduces a communication channel as an intermediary structure that connects the heat transfer plate and heat pipe. This channel serves as a mediator that enables fluid communication between the two previously independent capillary structures, facilitating improved fluid return without compromising capillary force.
2Productivity
If capillary force is increased to improve heat dissipation efficiency, then heat transfer performance improves, but the device complexity increases
Solution Approach 1:
The communication channel serves multiple functions: it connects the heat transfer plate and heat pipe, enables fluid communication between them, and provides a pathway for vaporized working fluid return. This multi-functionality improves heat dissipation efficiency without requiring separate complex structures for each function.
Solution Approach 2:
The patent merges the capillary networks of the heat transfer plate and heat pipe into a unified system through the communication channel. This consolidation allows both components to work together as a single capillary system, improving overall heat dissipation efficiency while reducing the complexity that would arise from maintaining separate, independent capillary structures.
