Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Battery modules in energy storage apparatuses experience reduced service life due to inadequate heat dissipation, as they are densely arranged and lack effective cooling mechanisms, leading to prolonged high-temperature operation.
Innovation Solution
The energy storage apparatus incorporates a cabinet with cyclic cooling units and an air supply duct, separating the inner cavity into air intake and return regions, allowing cooling gas to flow through a heat dissipation duct within the battery module, ensuring efficient heat dissipation and temperature control.
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 modules, creating distinct zones for cool air supply and hot air discharge. This segmentation enables organized airflow paths that improve heat dissipation while maintaining dense arrangement.
Solution Approach 2:
A heat dissipation duct is introduced as an intermediary component within the battery module, providing a dedicated channel for cooling gas to flow through the battery module interior. This mediator enables effective heat removal without requiring additional space, thus maintaining high cabinet deployment rate while improving heat dissipation.
2Power
If battery modules operate at high temperature for extended periods to maintain performance, then energy output is maintained, but service life deteriorates
Solution Approach 1:
The cyclic cooling unit establishes continuous circulation of cooling gas through the system, with gas continuously flowing from the air intake region, through the battery modules via heat dissipation ducts, to the air return region, and back to the cooling unit. This continuous cooling action maintains battery temperature within safe operating ranges, preserving service life while allowing sustained energy output.
Solution Approach 2:
The cyclic cooling system provides thermal feedback control by continuously circulating cooling gas through the battery modules, automatically adjusting heat removal based on thermal conditions. The cooling gas absorbs heat from battery modules and returns to the cooling unit for recooling, creating a self-regulating thermal management system that extends service life.

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 enhances heat dissipation, improves the reliability of battery modules, and prolongs their service life by effectively managing working temperatures.
Implementation Method 1
cooling gas with a low temperature in the air intake region flows into the battery module, and then flows 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
Implementation Method 2
The cyclic cooling unit is configured to supply cooling gas from the air inlet vent. 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

AI summary
This application provides an energy storage apparatus, including a cabinet, cyclic cooling units, a support, battery modules, and an air supply duct. The support is fastened in an inner cavity of the cabinet, the battery modules are fastened on the support, and the support and the battery modules jointly separate the inner cavity into an air intake region and an air return region. A heat dissipation duct communicating with the air intake region and the air return region is disposed in the battery module. The cyclic cooling unit is located outside the cabinet, and includes an air inlet vent and an air return vent. One end of the air supply duct communicates with the air inlet vent, and the other end of the air supply duct communicates with the air intake region. The air return vent communicates with the air return region. Cooling gas supplied by the cyclic cooling unit from the air inlet vent successively passes through the air supply duct, the air intake region, the heat dissipation duct, the air return region, and the air return vent, and flows back to the cyclic cooling unit. According to the energy storage apparatus in this application, a flow path for the cooling gas in the inner cavity is designed, so that the cooling gas can flow back only by mainly passing through the heat dissipation duct of the battery module. This ensures a heat dissipation effect of the energy storage apparatus, and helps to prolong a service life of the battery module.
