Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cooling fluid is supplied to multiple cooling tubes in a conventional battery pack, then cooling is provided to battery cells, but the cooling fluid cannot be distributed uniformly to each cooling tube, resulting in uneven flow and deteriorated cooling performance
Solution Approach 1:
The cooling fluid distribution member is divided into multiple distribution channels, with each channel corresponding to a specific cooling tube. This segmentation allows the cooling fluid to be distributed uniformly to each cooling tube through dedicated channels, preventing uneven flow and improving cooling performance reliability
Solution Approach 2:
The distribution channels are designed with different cross-sectional areas to match the specific cooling requirements of different battery cell groups. By adjusting the local flow characteristics of each channel, uniform cooling fluid distribution is achieved across all cooling tubes, resolving the uniformity issue
2Reliability
If a cooling fluid distribution member is added to achieve uniform distribution, then cooling performance improves, but the structural complexity of the battery pack increases
Solution Approach 1:
The cooling fluid distribution member is integrated with the battery module structure, combining the distribution function with the existing mechanical support structure. This merging approach achieves uniform cooling fluid distribution while minimizing additional structural complexity
Solution Approach 2:
The cooling fluid distribution member serves multiple functions: it distributes cooling fluid uniformly to multiple cooling tubes, provides structural support for the battery module, and facilitates thermal management. This multi-functionality improves cooling performance without proportionally increasing structural complexity
