First, the background of testing requirements for liquid cooling panels for new energy vehicles
The controller of the whole vehicle of the new energy vehicle will generate a lot of heat during the working process. As the core component to reduce the temperature of the chip, the sealing performance of the liquid cooling plate is very important. If the liquid cooling plate leaks, it will not only affect the heat dissipation effect, but also may cause damage to the controller and even cause safety accidents. Therefore, in the production process, the liquid cooling plate needs to undergo strict air tightness test and liquid running test to ensure long-term stable operation under actual working conditions.

At present, the test of liquid-cooled boards faces multiple challenges such as high-pressure environment, frequent insertion and unplugging, and sealing reliability. The traditional connection method has problems such as complicated operation and unstable sealing effect, which is difficult to meet the efficiency requirements of modern production lines. In response to this pain point, the application of professional fast-sealing connectors is particularly important.
II.G30The core technical advantages of the series of fast sealing connectors
GripSealG30Series Quick Seal CouplingIt is a special connection tool developed for high-voltage testing environments. Its design concept revolves around improving test efficiency and ensuring seal reliability, which is embodied in the following aspects:
1. Pressure assisted sealing mechanism
This series of joints features a unique pressure-assisted sealing design, which increases the sealing force when the test pressure is increased. This adaptive feature ensures that under high pressure test conditions, the joints are always sealed in an excellent state, effectively preventing leakage.2. Quick operation process
The operator only needs to align the connector with the pipe fitting and insert it, and then turn the handle.90This simplified operation process greatly reduces the test assistance time and improves the work efficiency of the production line. It is equally simple to disconnect, and the handle can be reset after the pressure returns to zero.3. Reliable grip structure
The joint is equipped with high-hardness locking minions, and the surface is designed with horizontal lines, which increases the contact area with the pipe fittings. This structure can firmly grasp the surface of the pipe fittings, and there will be no loosening even in high-pressure tests, ensuring the safety of the test process.4. Variety of material options
To adapt to different test scenarios and budget requirements,G30The series is available in stainless steel and aluminum alloy versions. The stainless steel material has excellent corrosion resistance and mechanical strength, making it suitable for long-term high-frequency use; the aluminum alloy version provides a more cost-effective option while ensuring basic performance.

In response to the specific testing requirements of new energy vehicle liquid cooling panels,G30Series Sealed ConnectorsShows good adaptability:
1High-pressure test scenario: For liquid-cooled plates with high test pressure requirements, stainless steel is recommendedG30-ASeries. This series can withstand higher working pressures, ensuring good sealing performance under severe test conditions.
2Routine test scenarios: For test stations with general pressure requirements, aluminum alloy models can fully meet the needs of use, while having more economical procurement and maintenance costs.
3Size adaptation range:G30Series can be covered6mmto19.5mmPipe sealing requirements in the outer diameter range. The nozzle size of the liquid cooling plate is usually within this range, and the user can choose the corresponding joint model according to the actual pipe diameter.
4High-frequency use and maintenance: For long-term high-frequency use of test stations, it is recommended to regularly check the wear of the sealing ring and the state of the locking minions. Timely replacement of worn parts can prolong the overall service life of the joint and maintain a stable test effect.
IV. Selection and use precautions
To ensureG30Series sealing jointTo achieve the best performance in practical applications, users should pay attention to the following points when selecting and using:
1. Select the appropriate material according to the test pressure
To determine the maximum pressure value of the liquid-cooled plate test, stainless steel is preferred in high-pressure environments, and aluminum alloy can be selected for conventional pressures to achieve the best balance between performance and cost.
2. Accurately measure the outer diameter of pipe fittings
Before use, it is necessary to accurately measure the outer diameter of the nozzle of the liquid-cooled plate and ensure that the joint of the corresponding specification is selected. The size matching directly affects the sealing effect and service life.3. Standardize the operation process
Operators should receive professional training and use the connector in strict accordance with the operating procedures. It is particularly important to note that the handle must be reset and disconnected after the test pressure is completely zero. This operating habit is essential to ensure safety and prolong the life of the connector.4. Establish a maintenance plan
For high-frequency test stations, it is recommended to establish a regular maintenance plan, including seal inspection, cleaning and maintenance, and replacement of worn parts, to ensure that the joints are always in optimum working condition.V. conclusion
With the continuous advancement of thermal management technology, the testing requirements for liquid cooling plates will also continue to increase. Fast sealing connector technology will continue to be optimized and upgraded to provide more complete test connection solutions for the new energy vehicle industry.
