Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If air cooling is used, then no separate cooling medium is required, but cooling efficiency is low
Solution Approach 1:
The patent changes the physical parameters of the cooling medium by using a fluid with optimized thermal conductivity and electrical insulation properties. The specific heat capacity, viscosity, and thermal expansion coefficient are adjusted to achieve both high cooling efficiency and electrical safety, resolving the contradiction between cooling performance and system simplicity.
2Productivity
If water cooling is used, then cooling efficiency is high, but direct contact with heat source is difficult
Solution Approach 1:
The patent modifies the electrical properties of the cooling fluid by adjusting its composition to achieve extremely low electrical conductivity (≤20 pS/m). This parameter change enables direct contact with electronic heat sources while maintaining high cooling efficiency, as the fluid can now penetrate into electrical components without causing short circuits.
3Productivity
If conventional coolants are used, then cooling function is provided, but thermal efficiency and chemical stability are insufficient
Solution Approach 1:
The patent employs a composite cooling fluid formulation combining multiple components with complementary properties. The base fluid provides thermal transfer capability while additives enhance chemical stability, corrosion resistance, and electrical insulation. This composite approach achieves both effective cooling and long-term reliability in electronic equipment.
