Electric Storage Holder with Wall Portions for Gas Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric storage apparatuses face inefficiencies in cooling due to column portions obstructing gas circulation, leading to ineffective temperature regulation, particularly for cells at the ends, and this issue extends to other electric storage devices like capacitors.
Innovation Solution
The design incorporates a holder body with wall portions and air vent portions that extend in specific directions to accommodate electric storage devices, allowing for unobstructed gas circulation and efficient cooling by forming inter-device air passages and inter-module air passages that maintain consistent gas flow rates across all cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If column portions are provided in the holder body to support electric storage devices, then the holder can accommodate and position the devices, but the column portions obstruct gas circulation and increase pressure loss
Solution Approach 1:
The invention removes the column portions from the holder body that were obstructing gas flow. Instead of using vertical column portions, the holder body is designed with wall portions that extend in the gas circulation direction, eliminating the obstruction while maintaining device accommodation capability.
Solution Approach 2:
The invention changes the orientation of the supporting structure from vertical columns (third direction) to horizontal walls (second direction parallel to gas flow). This dimensional reorientation allows the support structure to align with rather than obstruct the gas circulation path.
2Temperature
If gas circulates through air vent portions opened in the first direction, then cooling can be provided to electric storage devices, but column portions impede smooth gas circulation in the second direction
Solution Approach 1:
The invention extracts/removes the column portions that were creating resistance to gas flow. By eliminating these obstructive elements, gas can circulate smoothly through the air vent portions without impediment, maintaining high circulation efficiency while providing effective cooling.
Solution Approach 2:
The invention changes the geometric parameters of the holder body by replacing vertical column portions with horizontal wall portions. This parameter change modifies the flow path geometry to reduce turbulence and pressure loss, thereby improving gas circulation efficiency while maintaining cooling function.
3Productivity
If multiple column portions are spaced apart in the second direction to form air vent portions, then gas circulation paths are created, but the column portions necessarily increase pressure loss
Solution Approach 1:
Instead of creating air vent portions by spacing apart column portions (which creates obstruction), the invention inverts the approach by using continuous wall portions that extend parallel to the gas flow direction. This inversion eliminates the need for obstructive columns while maintaining gas circulation paths.
Solution Approach 2:
The invention optimizes the holder body design based on fluid flow principles, ensuring that the wall portions are positioned to minimize disruption to gas flow. The design allows smooth gas circulation through the air vent portions without creating unnecessary turbulence or pressure loss.
