Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional cooling channel is used, then the structure is simple, but the coolant flow is not uniformly distributed causing temperature deviations among battery cells
Solution Approach 1:
The cooling channel is divided into multiple segments (first cooling channel, second cooling channel, third cooling channel) with different flow directions. The dispersion member further segments the coolant flow into multiple streams using protrusions and recesses, creating uniformly distributed flow paths across the cooling plate surface.
Solution Approach 2:
Different regions of the cooling plate are provided with cooling channels having different flow directions (first direction, second direction, third direction). The dispersion member creates local variations in flow patterns through its protrusions and recesses, ensuring each region receives appropriately directed coolant flow for uniform temperature distribution.
2Reliability
If coolant flow is not dispersed, then the cooling channel structure is simple, but temperature deviations occur among battery cells
Solution Approach 1:
The dispersion member segments the coolant flow into multiple discrete streams using protrusions that create recesses. This segmentation disperses the concentrated coolant flow into uniformly distributed patterns across the cooling plate, preventing temperature deviations among battery cells.
Solution Approach 2:
The dispersion member acts as an intermediary component between the coolant supply and the battery cells. It modifies the coolant flow pattern before reaching the cooling channels, ensuring uniform distribution of cooling effect across all battery cells without requiring complex modifications to the cooling channels themselves.
3Productivity
If single-direction coolant flow is used, then the cooling channel is simple, but thermal management efficiency is insufficient
Solution Approach 1:
Different cooling channels are configured with different flow directions (first direction, second direction, third direction) to match the thermal distribution patterns of battery cells in different regions. This local optimization of flow direction enhances overall cooling efficiency while maintaining reasonable structural complexity.
Solution Approach 2:
The cooling system transitions from single-direction linear flow to multi-directional flow patterns by adding channels in first, second, and third directions. This dimensional expansion of flow paths improves thermal management coverage and efficiency across the battery module.
