Stacked Energy Storage Airflow Layout to Prevent Hot Air Recirculation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In energy storage devices stacked in double layers, heat dissipation issues arise as hot air from lower devices is sucked by the air inlet of upper devices, affecting their normal operation.
Innovation Solution
An energy storage apparatus with a support structure and an air guide structure that guides air away from the air outlet of one device to prevent hot air from entering the air inlet of adjacent devices, using hollowed-out or partitioned support layers and air guide hoods with inclined surfaces to direct airflow.

1Area of stationary object
If energy storage devices are stacked in double layers to save space, then space utilization is improved, but heat from lower devices is sucked by upper devices affecting normal operation
Solution Approach 1:
An air guide structure is introduced as an intermediary component between the lower and upper energy storage devices. This structure includes an air guide hood with a first air inlet and a first air outlet, where the air outlet is positioned away from the air inlet to prevent hot air from the lower device from being directly sucked into the upper device's air inlet, thus eliminating the harmful heat interference while maintaining the stacked configuration
Solution Approach 2:
The air inlet and air outlet of the air guide structure are positioned in different spatial dimensions and orientations. The air inlet is configured at a first position while the air outlet is configured at a second position away from the air inlet, creating a three-dimensional airflow path that prevents direct thermal coupling between stacked devices while maintaining compact space utilization
2Loss of energy
If air inlet is positioned on sidewall and air outlet at top for heat dissipation, then heat dissipation function is improved, but hot air from lower device enters upper device air inlet
Solution Approach 1:
The air guide hood is designed with asymmetric positioning of air inlet and air outlet. The first air inlet is positioned at a first position on the air guide hood while the first air outlet is positioned at a second position away from the air inlet, creating an asymmetric airflow path that prevents hot air recirculation while maintaining effective heat dissipation from the energy storage device

AI summary
An energy storage apparatus is provided. The energy storage apparatus includes: a support structure, which is provided with at least one support layer in a height direction of the support structure; an energy storage device, an air outlet is defined at the top of the energy storage device, and an air inlet is defined on a sidewall of the energy storage device, where the number of the energy storage device is at least two, the energy storage devices are arranged in at least two layers through the support layer, and the support layer between adjacent layers of energy storage devices is hollowed out or configured in a partitioning manner; and an air guide structure mounted on the energy storage device and in communication with an air inlet of the energy storage device, the air guide structure is configured to guide air from a position away from the air outlet of the energy storage device having the air guide structure or away from an air outlet of an adjacent energy storage device, thereby reducing the amount of heat of hot air that is discharged from the air outlet of the energy storage device and enters the air inlet of the energy storage device in an upper layer or the same layer, thereby avoiding affecting the normal operation of the energy storage device.
