Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If liquid cooling is applied to electronic components, then heat dissipation efficiency is improved, but damage to electronic components occurs due to dust, vibration, and performance degradation
Solution Approach 1:
The patent introduces a specially formulated perfluoro compound as an intermediary cooling medium between the cooling system and electronic components. This mediator provides effective heat transfer while being chemically inert and physically gentle on the components, avoiding direct harmful interactions. The perfluoro compound serves as a protective layer that enables cooling without transmitting damaging vibrations or allowing dust contamination.
Solution Approach 2:
The patent changes the physical and chemical parameters of the cooling fluid by using a perfluoro compound with specific properties: low viscosity for good heat transfer, high chemical stability to prevent component degradation, and controlled vapor pressure to minimize vibration effects. The azeotropic point between 40-60°C is optimized to provide effective cooling while maintaining component safety.
2Temperature
If conventional cooling fluids are used, then cooling performance is achieved, but capacitor performance decreases due to compromised electrical properties
Solution Approach 1:
The patent modifies the electrical and physical parameters of the cooling fluid by selecting a perfluoro compound with high dielectric strength and chemically stable molecular structure. This ensures the cooling fluid maintains excellent electrical insulation properties even at operating temperatures, preventing capacitor performance degradation while providing effective cooling.
Solution Approach 2:
The patent uses a composite perfluoro compound formulation combining PFBE with specific fluoroalkanes to create a cooling fluid with optimized properties. This composite material achieves the right balance between cooling efficiency, electrical stability, and chemical inertness to protect capacitors and other electronic components.
