Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery module assemblies suffer from poor heat dissipation due to gaps between the battery module and thermally conductive slurry or between the cooling component and the slurry, resulting in increased thermal resistance and reduced efficiency.
Innovation Solution
The battery module is designed with an injection channel on its limit frame, allowing thermally conductive slurry to be injected into an accommodation cavity formed between the battery module and the cooling component, ensuring full coverage and contact, thereby improving heat dissipation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If thermally conductive slurry is directly spread on the cooling component and the battery module is placed on it, then the manufacturing process is simple, but the heat dissipation performance is poor due to gaps between the battery module and slurry or cooling component and slurry
Solution Approach 1:
The patent introduces an injection channel as an intermediary structure that enables precise delivery of thermally conductive slurry to the accommodation cavity. This mediator ensures complete filling of the cavity without gaps, resolving the heat dissipation performance issue while maintaining manufacturing simplicity through the straightforward injection process
Solution Approach 2:
The battery module is segmented into distinct functional components: the limit frame with injection channel, the accommodation cavity, and the cooling component. This segmentation allows the injection channel to be integrated into the limit frame structure, enabling precise slurry delivery without complicating the overall device design
2Reliability
If thermally conductive slurry is injected into the accommodation cavity through the injection channel, then the heat dissipation efficiency is improved by full filling, but the device structure becomes more complex
Solution Approach 1:
The injection channel is merged with the limit frame structure, combining two functional elements into a single integrated component. This merging eliminates the need for separate injection channel structures, thereby improving heat dissipation efficiency without significantly increasing device complexity
Solution Approach 2:
The limit frame serves multiple functions: it provides structural support, defines the accommodation cavity, and incorporates the injection channel for slurry delivery. This multi-functionality reduces the number of separate components needed, maintaining device simplicity while achieving full cavity filling for optimal heat dissipation
