Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If capillary structures in the heat transfer plate and heat pipe are kept separate and independent, then the structure is simple and easy to manufacture, but the working fluid flow is reduced and heat dissipation efficiency decreases
Solution Approach 1:
The patent merges the capillary structures of the heat transfer plate and heat pipe by establishing a liquid-tight connection between them. The heat transfer plate's capillary structure extends into the heat pipe, and the heat pipe's capillary structure extends into the heat transfer plate, creating an integrated system where the working fluid flows continuously through both components without separation, thereby improving heat dissipation efficiency while maintaining manufacturing feasibility
2Productivity
If the capillary force of the structures is increased to improve heat dissipation efficiency, then the heat transfer performance improves, but the working fluid flow is restricted and return efficiency decreases
Solution Approach 1:
The patent applies local quality by creating different capillary force distributions in different regions of the heat transfer device. The heat transfer plate has a first capillary force value while the heat pipe has a second capillary force value, with the ratio controlled within specific ranges. This localized differentiation allows the working fluid to flow efficiently through the heat transfer plate while maintaining effective heat transfer in the heat pipe, balancing heat dissipation efficiency with working fluid flow and return efficiency
