Turnkey Solution for New Energy Intelligent Equipment
A water-cooling leak tightness test is a critical quality control procedure in the battery PACK production process. It is specifically designed to evaluate the sealing performance of water-cooling systems integrated into battery PACKs. As lithium battery modules generate substantial heat during charge and discharge cycles, water cooling plays a vital role in maintaining optimal operating temperatures. However, if the cooling system is not properly sealed, coolant leakage can cause overheating, short circuits, and even fire hazards.
This test ensures that the internal cooling circuit is completely sealed, allowing the coolant to flow smoothly without risk of leakage. It is an essential step in safeguarding battery safety, longevity, and thermal management efficiency.
Comprehensive Leak Detection
By pressurizing the battery PACK’s cooling channels, the system identifies even the smallest air or fluid leaks, guaranteeing reliable sealing.
Simulation of Real-World Conditions
The testing system can simulate actual operating environments, such as temperature fluctuations and liquid circulation under load conditions.
Automated and Intelligent Equipment
Modern leak testing machines integrate smart sensors and automation systems, enabling fast, accurate, and repeatable tests.
Real-Time Monitoring & Data Logging
Leak tests can be conducted in-line with real-time data acquisition, allowing immediate identification of defects and traceable quality control records.
Non-Destructive and Safe
Leak tests are non-destructive and designed to ensure that the battery PACKs remain intact and safe for further assembly and use
Water-cooling leak tightness testing is widely used in the production of high-performance battery systems, particularly in:
Any battery module using a liquid cooling system must undergo strict leak testing to ensure operational safety and compliance.
When choosing a water-cooling leak tightness testing solution, manufacturers should consider:
Ensure the testing equipment matches your specific battery design, cooling pipe layout, and sealing materials.
Higher sensitivity allows the detection of micro-leaks that could cause long-term performance degradation.
Inline automated systems reduce labor costs and improve testing speed, especially for mass production environments.
Consider how many PACKs can be tested per hour and whether the test speed meets your production line capacity.
A robust data logging system helps with compliance, root cause analysis, and continuous quality improvement.
Choose suppliers that provide installation guidance, training, and responsive technical support.
