Ventilation Plates for Uniform Cooling in Energy Storage Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current energy storage container ventilation systems suffer from uneven air distribution and temperature inconsistencies among battery racks, leading to inefficient cooling and potential safety hazards due to the complexity of air duct designs and inertia-induced cold air accumulation.
Innovation Solution
The energy storage container ventilation system employs ventilation plates with adjustable structures and orientations at the interface between air ducts and battery boxes to control air intake volume, ensuring uniform cooling across all batteries by fine-tuning the number and arrangement of ventilation holes and using shielding sheets to adjust ventilation areas, thereby reducing temperature differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single air conditioner is used to cool multiple columns of battery racks, then the cooling coverage is improved, but the air volume distribution among battery racks becomes uneven
Solution Approach 1:
The patent divides the air duct system into multiple independent air ducts, with each air duct serving a specific battery rack. This segmentation allows independent control of air volume for each rack, resolving the uneven distribution problem while maintaining comprehensive cooling coverage through centralized air conditioner operation.
Solution Approach 2:
The patent implements local quality control by equipping each air duct with adjustable air volume control components (such as dampers or adjustable outlets). This enables localized adjustment of air flow to each battery rack according to its specific cooling requirements, achieving uniform air volume distribution across all racks while using a single central air conditioner.
2Manufacturing precision
If stepped or divergent air ducts are designed to evenly distribute air, then the air distribution uniformity is improved, but the structural complexity increases
Solution Approach 1:
Instead of designing complex stepped or divergent air duct structures, the patent segments the air distribution system into multiple simple, straight air ducts. Each duct is equipped with independent air volume control components, achieving uniform air distribution through controlled flow regulation rather than geometric complexity.
Solution Approach 2:
The patent changes the control parameter from geometric shape (stepped or divergent duct designs) to flow parameters (air volume control through dampers or adjustable outlets). This allows simple duct structures to achieve uniform air distribution by adjusting flow rates to match each battery rack's cooling requirements.
3Temperature
If cold air flows in from the top of battery rack, then the cooling effect is improved, but cold air accumulates on the bottom due to inertia causing uneven cooling
Solution Approach 1:
The patent introduces dynamic adjustment capabilities through air volume control components in each air duct. These components can be adjusted based on actual temperature measurements and cooling demands, allowing the system to adaptively compensate for cold air accumulation effects and maintain uniform temperature distribution throughout each battery rack.
Solution Approach 2:
The patent implements feedback control by monitoring temperatures in battery racks and adjusting air volume control components accordingly. Temperature sensors detect hot spots or uneven cooling patterns, and the control system adjusts damper positions or outlet openings to redistribute cold air flow, eliminating accumulation effects and achieving uniform temperature distribution.
