Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If water-cooling method is used to cool the coil, then cooling efficiency is improved, but leakage risk and insulation complexity increase
Solution Approach 1:
The patent introduces a thermal conductor plate as an intermediary component between the coil and cooling water. The plate conducts heat from the coil to the cooling water, enabling efficient heat transfer while maintaining physical separation and insulation between the high-voltage coil and conductive cooling water, thus eliminating leakage risks
Solution Approach 2:
The cooling system is segmented into distinct functional components: the coil, the thermal conductor plate, and the cooling water chamber. This segmentation allows each component to perform its specific function optimally while reducing the risk of direct contact and potential leakage between the coil and cooling water
2Reliability
If air-cooling method is used to cool the coil, then leakage risk is reduced, but cooling efficiency decreases
Solution Approach 1:
The patent employs a water-based cooling system (hydraulic principle) instead of air cooling, utilizing the superior heat capacity and thermal conductivity of water to achieve efficient heat dissipation from the coil through the thermal conductor plate
3Reliability
If oil-cooling method is used to cool the coil, then leakage risk is reduced, but cooling efficiency decreases due to slow heat transfer
Solution Approach 1:
The patent changes the thermal parameters of the cooling system by using water instead of oil, leveraging water's higher thermal conductivity and heat capacity to achieve rapid and efficient heat transfer from the coil, eliminating the slow heat transfer characteristic of oil-based systems
4Temperature
If compressor or radiator method is used as cooling unit, then cooling capability is improved, but vibrations and noises increase
Solution Approach 1:
The patent extracts and eliminates the compressor and radiator components from the cooling system, replacing them with a simpler water circulation system that passes cooling water directly through or around the coil, thereby removing the sources of vibrations and noises associated with mechanical compression and radiation systems
5Temperature
If direct water contact with coil is implemented, then cooling efficiency is improved, but insulation complexity and leakage risk increase
Solution Approach 1:
The thermal conductor plate serves as an intermediary that enables efficient heat transfer between the coil and cooling water without requiring direct contact. This intermediate component simplifies the insulation requirements while maintaining high cooling efficiency through effective thermal conduction
