Stackable Battery Pack Cooling Enclosure for Modular Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current battery packs have a low degree of modularity, requiring additional fixing frames for assembly, which results in inefficient assembly processes.
Innovation Solution
A battery pack design featuring enclosure plates surrounding a liquid cooling plate with integrated inlet and outlet pipes, accommodating cavities, and engaging connecting components on the top and bottom surfaces, allowing for easy stacking and assembly of multiple battery packs into a module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If additional fixing frames are used to connect multiple battery packs, then the battery module assembly is achieved, but the assembly efficiency is reduced and device complexity increases
Solution Approach 1:
The patent integrates the connecting component directly into the enclosure plate structure, merging the functions of the enclosure plate and the fixing frame into a single integrated component. This eliminates the need for separate fixing frames and simplifies the assembly process by reducing the number of parts and assembly steps.
Solution Approach 2:
The enclosure plate is designed with dual functionality: it serves as both the protective enclosure structure and the connecting component for joining battery packs. The connecting components on the top and bottom surfaces enable direct stacking and connection of multiple battery packs without requiring additional specialized fixing structures.
2Productivity
If battery packs are designed with high modularity for easy stacking, then assembly efficiency improves, but structural strength may be compromised
Solution Approach 1:
The connecting component is integrated into the enclosure plate itself, creating a unified structure that provides both the enclosure function and the mechanical connection function. This integration ensures that the structural strength is not compromised by separate weak connection elements, while still enabling efficient stacking assembly.
Solution Approach 2:
The connecting component features a groove structure that provides mechanical interlocking between stacked battery packs. The groove and corresponding protrusion design creates a robust mechanical connection that maintains structural integrity while enabling straightforward stacking assembly.
