Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a greater number of battery units are used to achieve greater voltage and current output, then the power output is improved, but the volume of the battery pack increases and more heat is generated
Solution Approach 1:
The cooling plate utilizes both sides of its structure to contact battery units, effectively doubling the heat dissipation surface area within the same volume. This dimensional utilization allows the battery pack to accommodate more battery units for higher power output without proportionally increasing the overall pack volume, as the cooling plate serves dual-sided thermal management.
Solution Approach 2:
The cooling plate is designed to simultaneously contact and cool multiple battery units on both its first and second sides, making it a multi-functional component that serves several battery units at once. This universal cooling approach allows efficient heat dissipation for a larger number of battery units without requiring separate cooling components for each unit, thus managing higher power output within limited space.
2Power
If a greater number of battery units are used to achieve greater voltage and current output, then the power output is improved, but the heat generation increases
Solution Approach 1:
The cooling plate extends its heat dissipation capability to both sides, creating a three-dimensional heat transfer structure that contacts battery units on the first side, second side, and through the fluid channel. This multi-directional thermal contact area allows the system to manage heat from a greater number of battery units producing higher power output, effectively distributing thermal load across multiple surfaces.
Solution Approach 2:
The cooling plate acts as an intermediary thermal management component between the battery units and the cooling fluid. It receives heat from multiple battery units through its first and second sides, then transfers this heat through the fluid channel where cooling fluid circulates. This intermediary function enables efficient heat removal from high-power battery configurations.
3Volume of stationary object
If the battery pack volume is reduced to fit limited vehicle space, then the compactness is improved, but the heat dissipation capability may be compromised
Solution Approach 1:
The cooling plate maximizes heat dissipation surface area by utilizing both sides of the plate structure within a compact volume. This allows the battery pack to maintain a compact form factor while achieving sufficient heat dissipation capability through the expanded thermal contact area on both the first and second sides of the cooling plate.
Solution Approach 2:
The cooling plate merges the functions of multiple cooling surfaces into a single integrated component. By combining the first side, second side, and fluid channel into one unified structure, the design achieves comprehensive heat dissipation capability within a compact volume, eliminating the need for separate cooling components that would increase overall pack size.
