Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If air cooling forced convection is used for battery pack cooling, then the cooling system can be implemented, but the air flow cannot be uniformly dispersed, resulting in dead zones and non-uniform temperature distribution
Solution Approach 1:
The patent transitions from air cooling to liquid cooling by introducing a cooling liquid circulation system. The cooling liquid flows through cooling channels formed by the battery cooling plate and battery thermal management plate, providing more uniform heat transfer and eliminating dead zones that occur with air cooling convection.
2Area of stationary object
If conventional layout of liquid cooling module components is used, then the system can function, but the unit size becomes large and occupies more area
Solution Approach 1:
The patent integrates multiple components into a compact arrangement where the battery cooling plate and battery thermal management plate are positioned adjacent to each other, forming integrated cooling channels. The heat exchanger is efficiently coupled with the cooling liquid circulation system, and the refrigeration device is strategically positioned to maximize space utilization, thereby reducing the overall system area while maintaining functional合理性.
3Device complexity
If cooling liquid system and heat exchanger are separately arranged, then maintenance is easier, but space utilization is poor and structure is not compact
Solution Approach 1:
The patent divides the cooling system into modular components including the battery cooling plate, battery thermal management plate, heat exchanger, and refrigeration device. These segmented modules are arranged in a compact sequence, allowing each component to be independently accessed and maintained while maintaining overall structural compactness and efficient space utilization.
