Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a conventional cooling plate with simple channels is used, then the structure is simple and easy to manufacture, but the coolant flow is not uniform and temperature deviations occur among battery cells
Solution Approach 1:
The cooling plate divides the cooling function into multiple independent channels (first cooling channel, second cooling channel, third cooling channel) that can be designed and optimized separately. Each channel serves specific battery cells, allowing tailored cooling paths that improve temperature uniformity without requiring complete redesign of the entire cooling system.
Solution Approach 2:
The patent implements different channel configurations in different regions of the cooling plate. The first and second channels provide linear cooling paths for respective battery cells, while the third channel provides diagonal cooling. This local customization of cooling paths ensures that each region receives appropriate cooling based on its specific thermal requirements, improving overall temperature uniformity.
2Temperature
If coolant flow is concentrated in certain areas, then cooling efficiency in those areas improves, but temperature deviations occur and some battery cells are overheated
Solution Approach 1:
The cooling plate segments the coolant flow into multiple independent channels, each serving specific battery cells. This segmentation ensures that coolant is distributed to different regions simultaneously and uniformly, preventing concentration in single areas and maintaining consistent cooling efficiency across all battery cells.
Solution Approach 2:
The cooling channel design creates equipotential cooling conditions by providing multiple parallel paths (first, second, and third channels) with similar flow characteristics. This ensures that coolant flows uniformly through each channel, creating equal cooling potential across all battery cells and preventing temperature deviations.
3Temperature
If the cooling plate uses multiple channels with different directions, then temperature uniformity improves, but the manufacturing complexity increases
Solution Approach 1:
The patent merges multiple cooling functions into a single integrated cooling plate structure. The first, second, and third channels are combined in one plate, with the third channel connecting the first and second channels. This merging approach achieves temperature uniformity through multi-directional cooling while maintaining a unified structure that is easier to manufacture than separate cooling components.
Solution Approach 2:
The cooling plate is designed as a multi-functional component that simultaneously provides linear cooling (first and second channels) and diagonal cooling (third channel). This universal design achieves temperature uniformity across different battery cell arrangements while maintaining a single standardized cooling plate structure that simplifies manufacturing and installation.
