Segmented Battery Retainment Block for Thermal Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery retainment blocks face inefficiencies in heat radiation due to the difficulty in applying cooling air between adjacent batteries, leading to inadequate heat dissipation.
Innovation Solution
A battery retainment block design featuring cylindrical block pieces with alternating large and small diameter sections, where the small diameter sections form a gap for a circulation space between adjacent pieces, allowing for efficient air circulation and heat radiation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a thermal runaway prevention wall is provided along the entire axial direction of the battery between two adjacent batteries, then thermal runaway prevention is improved, but cooling air circulation between batteries is blocked
Solution Approach 1:
The thermal runaway prevention wall is segmented into two parts: a first thermal runaway prevention wall at the upper end and a second thermal runaway prevention wall at the lower end of the battery, with a gap between them. This segmentation allows cooling air to pass through the gap while maintaining thermal runaway prevention functionality at both ends of the battery.
Solution Approach 2:
The cooling air circulation is enabled by creating a vertical gap dimension between the upper and lower thermal runaway prevention walls, allowing air flow in the axial direction while the walls themselves maintain their barrier function horizontally between adjacent batteries.
2Stability of the object's composition
If block pieces are bonded together to form a battery retainment block, then structural stability is improved, but heat radiation efficiency deteriorates
Solution Approach 1:
The battery retainment block is segmented into multiple block pieces that are bonded together, with circulation spaces created between adjacent block pieces. This segmentation allows the structure to maintain stability through bonding while providing channels for cooling air circulation to improve heat radiation.
Solution Approach 2:
Cooling air acts as an intermediary medium that flows through the circulation spaces between bonded block pieces, enabling heat transfer from the batteries to the surrounding environment while maintaining the structural integrity of the bonded block assembly.
3Strength
If the entire periphery of the battery is covered by block pieces, then mechanical protection is improved, but cooling air application is prevented
Solution Approach 1:
The block pieces are segmented to create circulation spaces between them, so that while the batteries are mechanically protected by the block structure, gaps remain through which cooling air can reach the battery surfaces for effective heat dissipation.
