Solution Overview
Problem
High-temperature storage batteries, such as sodium-sulfur batteries, face inefficiencies due to heat discharge into the interior of their containers, leading to temperature differences and reduced operating efficiency, and existing solutions complicate the structure with separate units for air inlet and exhaust port control.
Innovation Solution
A storage battery container with air supply and exhaust portions, where air inlet ports are opened and closed based on power supply and variable heat dissipation device operation, and air exhaust ports are correspondingly controlled to prevent heat discharge into the container interior, using a simplified structure with electromagnetic chucks and filters to manage airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If heat dissipation devices are added to prevent excessive temperature rise in storage batteries, then temperature control is improved, but heat is discharged into the container interior causing temperature differences and reduced operating efficiency
Solution Approach 1:
The invention extracts the harmful heat from the storage battery system by providing dedicated exhaust ports that vent hot air directly to the exterior of the container. The exhaust ports are positioned to receive hot air from the heat dissipation devices and discharge it outside the container, preventing heat accumulation and temperature differences in the container interior, thus maintaining high operating efficiency while achieving effective temperature control.
Solution Approach 2:
The invention introduces air inlet ports as intermediary elements that supply fresh air to the heat dissipation devices. These air inlet ports work in conjunction with the exhaust ports to create a controlled airflow path, where cool air enters through the inlet ports, absorbs heat from the batteries, and exits through the exhaust ports, thereby mediating the thermal management process without allowing heat to accumulate in the container interior.
2Ease of operation
If separate units are provided to control air inlet and exhaust ports, then port control is improved, but device structure becomes complicated
Solution Approach 1:
The invention merges the control functions of air inlet ports and exhaust ports into a unified structure. Both types of ports are integrated into the container body with coordinated positioning and control mechanisms, eliminating the need for separate control units. The ports work together as an integrated airflow management system, simplifying the overall device structure while maintaining effective control over air circulation and heat dissipation.

AI summary
A storage battery container is provided with an air supply part having an air supply port provided to the bottom surface, a variable heat dissipation device that balances accumulated heat inside the storage battery, and an air discharge part of a rear surface having an air discharge port correspondingly provided to a heat release part of the variable heat dissipation device. The air supply part puts the air supply port in an open state when power is being supplied, and puts the air supply port in a closed state when the power supply stops. The air discharge part puts the air discharge port in an open state when the variable heat dissipation device is actuated, and puts the air discharge port in a closed state when the actuation of the variable heat dissipation device stops.
