Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fluid collectors in battery systems are prone to damages such as bending or breakage due to unsupported weight, which can compromise the integrity and functionality of the battery system.
Innovation Solution
A battery design that includes a heat exchanger bearing the battery cell and connected to a fluid collector, with a support member positioned below the fluid collector to transfer at least part of the battery cell's weight, reducing the likelihood of damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the fluid collector is suspended outside the case without support, then the structure is simple and easy to manufacture, but the fluid collector is prone to bending or breakage due to the weight of the battery cell
Solution Approach 1:
The heat exchanger serves as an intermediary component between the battery cell and the fluid collector. It is heat-conductively connected to the battery cell and connected to the fluid collector, allowing the heat exchanger to bear the battery cell weight and transfer it to the fluid collector, thereby supporting the fluid collector without requiring additional support structures
Solution Approach 2:
The heat exchanger performs multiple functions: it conducts heat from the battery cell to the fluid collector for thermal management, and simultaneously serves as a support structure to bear the battery cell weight and prevent fluid collector damage. This multi-functionality eliminates the need for separate support components
2Device complexity
If the heat exchanger is positioned only between the battery cell and the case, then the structure is simple, but the heat management efficiency is reduced
Solution Approach 1:
The heat exchanger is positioned between the battery cell and the cover plate (above the battery cell) rather than only between the battery cell and the case (below the battery cell). This spatial repositioning in another dimension allows the heat exchanger to conduct heat upward through the cover plate to external components, enabling heat dissipation from both sides of the battery system simultaneously
3Device complexity
If the fluid collector is directly connected to the battery cell without a heat exchanger in between, then the structure is simpler, but the fluid collector bears full weight and is prone to damage
Solution Approach 1:
The heat exchanger is introduced as an intermediary component between the battery cell and the fluid collector. It bears the battery cell weight and transfers it to the fluid collector, preventing the fluid collector from bearing the full weight directly while maintaining the connection necessary for heat management functionality
