Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a water-cooled intercooler is used, then stable cooling efficiency can be maintained, but the cooling efficiency is lower than that of air-cooled intercoolers
Solution Approach 1:
The patent combines the water-cooled intercooler system with the air conditioning system by integrating the condenser of the AC system into the cooling water circuit. The condenser cools the cooling water using refrigerant, creating a hybrid system that merges advantages of both water-cooled stability and enhanced cooling capacity
Solution Approach 2:
The condenser of the air conditioning system serves dual functions: it cools the refrigerant for the AC system and simultaneously cools the cooling water for the intercooler. This multi-functionality allows the same component to address multiple thermal management needs, improving overall system efficiency
2Productivity
If an air-cooled intercooler is used, then cooling efficiency is good, but stable efficiency cannot be expected due to changes in ambient temperature
Solution Approach 1:
The patent introduces cooling water as an intermediary medium between the intercooler and the condenser. The cooling water absorbs heat from the intake air in the intercooler and transfers it to the refrigerant in the condenser, providing a stable thermal link that is less affected by ambient temperature variations compared to direct air-cooling
3Temperature
If cooling water temperature is reduced to improve intercooler performance, then intake air temperature decreases, but system complexity increases
Solution Approach 1:
The system uses the air conditioning system's own condenser to cool the intercooler's cooling water, making the intercooler self-cooling through the vehicle's existing thermal management infrastructure. This eliminates the need for separate cooling systems while reducing intake air temperature
