Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If cooling channels are disposed in parallel with battery cells, then heat exchange capability is improved, but thermal conductivity between cooling channels and battery cells is insufficient due to lack of close adherence
Solution Approach 1:
The connecting parts of the heat exchange member are bent in a curved shape to follow the contour of the battery cell surfaces. This curvature enables the heat exchange member to closely adhere to the battery cells, maximizing the contact area and improving thermal conductivity between the cooling channels and battery cells.
Solution Approach 2:
A filler material is applied to the connecting parts of the heat exchange member to enhance thermal conductivity. The filler acts as an intermediary substance that fills gaps and improves thermal contact between the heat exchange member and battery cells, thereby improving overall heat exchange capability.
2Reliability
If multiple components are used to achieve close adherence, then thermal conductivity is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The partition walls and connecting parts are integrated into a single heat exchange member component. This merging of components simplifies the overall structure, reduces the number of parts that need to be assembled, and lowers manufacturing complexity while maintaining the bent shape and filler application for close adherence to battery cells.
