Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In energy storage devices, the existing cooling assemblies attached to the sides of battery modules lead to inefficient heat dissipation and temperature inconsistencies between cells, causing large temperature differences and potential safety issues.
Innovation Solution
The integration of heat insulation supports within the case of the energy storage device, which fix the cooling assemblies and reduce heat exchange between them and the case, ensuring even temperature distribution and improved cooling efficiency by acting as a triangular or four-point support to stabilize the cooling assemblies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the cooling assembly is fixed to the side board of the battery module, then the cooling assembly can be stably positioned, but heat transfer occurs between the cooling assembly, side board, and battery box, leading to large temperature differences in the battery module
Solution Approach 1:
The patent introduces heat insulation supports as intermediary components between the cooling assembly and the battery module side board. These supports are made of heat-insulating materials and feature buffering structures that reduce direct thermal contact while maintaining mechanical support, thereby preventing harmful heat transfer paths that cause temperature non-uniformity in the battery module
Solution Approach 2:
The cooling assembly is divided into multiple independent cooling units, each fixed to the side board through separate heat insulation supports. This segmentation allows independent thermal management for different regions, preventing heat accumulation and promoting uniform temperature distribution across the entire battery module
2Ease of manufacture
If the cooling assembly is fixed to the side board, then the structure is simple and easy to manufacture, but heat dissipation efficiency is reduced due to heat transfer through the side board and battery box
Solution Approach 1:
Heat insulation supports serve as intermediary components that block heat transfer paths through the side board and battery box. These supports maintain the structural simplicity of the original design while effectively reducing energy loss through unwanted thermal conduction, thereby improving heat dissipation efficiency without significantly complicating the manufacturing process
