[0040] Embodiment:

[0041] The essence of anti-siphon is to prevent liquid backflow caused by negative pressure. In a liquid cooling system, when the negative pressure inside the pipe is greater than the outside, the surrounding liquid may be sucked into the pipe, causing contamination or damage to the equipment. Therefore, measures need to be taken to prevent siphon phenomenon.

[0042] The test takes various anti-siphon measures, including but not limited to high-pressure injection, use of oil-resistant polyurethane AB glue, and replacement of the board end with a water crystal head connection method using a similar navigation plug waterproof design. These measures aim to prevent siphon phenomenon through different mechanisms.

[0043] Capillary phenomenon refers to the phenomenon of liquid rising or falling in a thin tube, which is related to the surface tension of the liquid and the adhesion of the tube wall to the liquid. In an immersion liquid cooling system, capillary phenomenon may affect the flow and distribution of liquid, so it needs to be studied and the capillary phenomenon outside the wire is eliminated.

[0044] Capillary phenomenon is influenced by various factors, including the properties of the liquid (such as surface tension, density, viscosity, etc.), the material and roughness of the tube wall, temperature, and pipe diameter. The test will block the SR on the outside of the wire in a similar inverted funnel shape.

[0045] Test equipment

[0046] Select appropriate test materials and equipment, build a test platform, and ensure that the test conditions meet the requirements.

[0047] Test operation

[0048] Follow the pre-set test plan to operate, including liquid injection, temperature control, variable adjustment, etc. At the same time, record the key data during the test process, such as the height and time of liquid rising or falling.

[0049] Test repetition and comparison

[0050] To ensure the reliability of the test results, the same set of test conditions needs to be repeated several times, and the test results under different conditions need to be compared and analyzed.

[0051] Data collection

[0052] During the test, collect and record key data in real time. These data include but are not limited to the height and time of liquid rising or falling.

[0053] Data analysis method

[0054] The collected data is sorted and analyzed, and the test results under different conditions are compared and analyzed to obtain the influence of anti-siphon and capillary phenomenon in the immersed liquid cooling system and the optimization scheme.

[0055] Anti-siphon design optimization

[0056] By improving the jumper interface design, adding anti-siphon structure and other measures, the occurrence of siphon phenomenon is effectively prevented. At the same time, the cable outer skin is made of anti-siphon material, which further reduces the risk of siphon.

[0057] Capillary phenomenon suppression measures

[0058] The cable is treated inside by special process to prevent cooling liquid from penetrating; SR is installed outside in the form of inverted funnel to reduce capillary effect and prevent cooling liquid from climbing. In addition, the cooling liquid is replaced regularly to maintain its cleanliness, so as to reduce the probability of capillary phenomenon.

[0059] Test environment control and monitoring technology improvement

[0060] The monitoring technology is improved by using equivalent method, alternative method and other methods to ensure the accuracy of test data. At the same time, the cable state is monitored periodically to improve the accuracy of test data.

[0061] The design of immersed liquid cooling network jumper is optimized to improve its anti-siphon and capillary phenomenon performance. The connector is changed to the matching form, and the protection method is changed from the board end and the line end at the same time to prevent siphon and capillary. By preventing these two phenomena, the service life of the network jumper can be prolonged, and the reliability of the entire liquid cooling system can be improved.
