Battery Cooling Line Check Valve for Integrated Fire Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery systems face challenges in compact and cost-effective temperature control and fire extinguishing, as traditional temperature control devices require additional space and complex extinguishing devices that are costly and inefficient.
Innovation Solution
A temperature control device with a check valve in the temperature control line allows for continuous flow in the normal direction while blocking in the reverse direction, enabling the same device to both control temperature and extinguish fires by directing the temperature control fluid to the source of the fire through a leakage point created by a safety section or valve element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional extinguishing devices are installed in battery systems to ensure rapid fire suppression, then fire suppression capability is improved, but installation space increases and device complexity increases
Solution Approach 1:
The temperature control device is designed to perform dual functions: normal temperature control during operation and fire suppression during emergencies. The same pump device, temperature control line, and temperature control fluid are used for both cooling the battery subsystems and extinguishing fires, eliminating the need for separate extinguishing devices and reducing overall system complexity
Solution Approach 2:
The temperature control system serves itself by using its existing components for fire suppression. The pump device automatically or manually directs the temperature control fluid through the temperature control line to the fire location, allowing the system to suppress fires using its own integrated resources without requiring external extinguishing systems
2Reliability
If additional extinguishing devices are installed in battery systems to ensure rapid fire suppression, then fire suppression capability is improved, but installation space increases
Solution Approach 1:
The temperature control device is designed to perform dual functions: normal temperature control during operation and fire suppression during emergencies. The same pump device, temperature control line, and temperature control fluid are used for both cooling the battery subsystems and extinguishing fires, eliminating the need for separate extinguishing devices and reducing overall system complexity
Solution Approach 2:
The fire suppression function is merged with the existing temperature control system. The pump device, temperature control line, and temperature control fluid serve both cooling and fire suppression purposes, combining two functions into one integrated system to minimize installation space
3Reliability
If check valve is arranged in the temperature control line to enable bidirectional flow control for fire extinguishing, then fire suppression capability is improved, but device complexity increases
Solution Approach 1:
The check valve acts as an intermediary component that enables bidirectional flow control in the temperature control line. It allows the temperature control fluid to flow in the normal direction during cooling operation and automatically directs flow in the reverse direction toward the fire location during fire suppression, facilitating the dual-function capability with a single simple mechanical component
Solution Approach 2:
The fire suppression capability is extracted and enabled through the addition of a simple check valve to the existing temperature control system. This single component extraction allows the system to achieve bidirectional flow control and fire suppression functionality without requiring complex additional devices or systems

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 solution allows for effective temperature control and fire extinguishing within the existing device, reducing the need for additional extinguishing devices, enhancing safety and compactness by using existing components to manage thermal energy and direct fluid flow to the fire location.
Implementation Method 1
the check valve blocks in a second flow direction, wherein the second flow direction is opposite to the first flow direction
Implementation Method 2
thermal energy, in other words waste heat from the battery subsystems, can be absorbed by the temperature control fluid and transported away from the battery subsystems
Implementation Method 3
Through a thermally conductive connection of the temperature control line, for example a temperature control section of the temperature control line, with the individual battery subsystems of a battery system, thermal energy, in other words waste heat from the battery subsystems, can be absorbed by the temperature control fluid and transported away from the battery subsystems, or brought to the battery subsystems by the temperature control fluid and transferred to them
