Battery Rack Spray Pipe Layout for Fast Fire Agent Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire extinguishing systems for energy storage systems struggle to effectively suppress high-pressure fires in battery cells due to increased flame and ejection pressure, necessitating a more efficient method to quickly deliver fire extinguishing agents to multiple fire points.
Innovation Solution
A fire extinguishing device with a storage box, supplier, distributor, and spray pipes is designed to rapidly distribute fire extinguishing agents through a network of pipes and valves, allowing for targeted delivery based on fire detection, with sensors and controllers adjusting flow rates and directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If general fire suppression equipment is used, then the system is simple and cost-effective, but it cannot effectively suppress high-pressure fires in battery cells with increased flame and ejection pressure
Solution Approach 1:
The fire suppression system is divided into multiple independent spray pipes, each equipped with its own control valve. This segmentation allows targeted suppression at different locations and enables the system to handle high-pressure fires from multiple points simultaneously, improving overall effectiveness without requiring a completely complex centralized system
Solution Approach 2:
The system incorporates controllable valves that can dynamically adjust or completely close off individual spray pipes based on fire detection. This dynamic control allows the system to adapt to different fire scenarios, directing extinguishing agents precisely where needed while maintaining system simplicity through on-demand activation
2Loss of time
If fire extinguishing agents are supplied from a single location, then the system structure is simple, but the time to reach multiple fire points is extended
Solution Approach 1:
The distribution system transitions from a single-point linear supply to a multi-dimensional network with spray pipes positioned at different heights and locations within the rack frame. This spatial distribution enables simultaneous coverage of multiple fire points, dramatically reducing delivery time while maintaining manageable system complexity through modular pipe and valve components
3Device complexity
If the storage box is located at the rear of the rack frame, then the system structure is simplified, but the flow direction must be changed to reach upper battery modules
Solution Approach 1:
The rack pipe incorporates a dynamic flow direction change capability, allowing the extinguishing agent to be redirected upward to reach battery modules at different heights. This dynamic flow control maintains the simplified rear-mounted storage box structure while ensuring efficient distribution to all locations within the rack frame

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enhances fire suppression by reducing the time taken for extinguishing agents to reach fire points, increasing the spray amount, and optimizing delivery based on fire location and extent, thereby improving fire extinguishment speed and efficiency.
