Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Battery modules in energy storage apparatuses are densely arranged, leading to poor heat dissipation and reduced service life due to high operating temperatures.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If battery modules are densely arranged to increase cabinet deployment rate, then space utilization is improved, but heat dissipation capability deteriorates
Solution Approach 1:
The inner cavity is segmented into air intake region and air return region by the support and battery module arrangement, creating distinct zones for cool air supply and hot air discharge. This segmentation enables effective heat dissipation while maintaining high-density battery module placement.
Solution Approach 2:
A heat dissipation duct is introduced as an intermediary component within the battery module to facilitate controlled airflow through the battery cells. This mediator enables efficient heat removal without requiring reduced deployment density.
2Productivity
If battery modules operate at high temperature for extended periods to maintain deployment efficiency, then space utilization is maintained, but service life deteriorates
Solution Approach 1:
The cyclic cooling unit establishes continuous airflow circulation through the battery modules, with cooling gas continuously supplied through the air supply duct, passing through the heat dissipation duct, and returning via the air return duct. This continuous cooling action maintains reliable operating temperatures while preserving high deployment rate.
Solution Approach 2:
The cyclic cooling system creates a feedback loop where heated air from the battery modules is continuously captured, cooled, and redistributed back to the air intake region. This closed-loop feedback mechanism ensures sustained temperature control and extends battery service life.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design achieves better heat dissipation, maintains battery module reliability, and extends its service life by controlling working temperatures effectively.
Implementation Method 1
The cooling gas successively passes through the air supply duct, the air intake region, the heat dissipation duct, and the air return region, and finally flows back to the cyclic cooling unit from the air return vent
Implementation Method 2
cooling gas with a low temperature in the air intake region may flow into the battery module, and then flow into the air return region after being fully in contact with, in the heat dissipation duct, gas with a high temperature in the battery module
