Immersed liquid cooling technology is an innovative heat dissipation method that achieves efficient heat dissipation by completely immersing electronic equipment in a medium with high thermal conductivity. Compared with traditional air cooling, liquid cooling technology has higher heat dissipation efficiency and can solve the heat dissipation problem of high-performance electronic equipment. This technology is widely used in high-performance computing, data centers, artificial intelligence and other fields.

[0034] S2: Screening of wire substrate: Select appropriate substrate according to the cooling oil composition and perform modification on the substrate;

[0038] Furthermore, in step S5, the prepared universal data center immersion liquid cooling system dedicated power harness is subjected to siphon and capillary tests, thermal life tests, electrical performance tests, and flame retardant performance evaluation tests.

[0039] Example:

[0040] The essence of anti-siphonage is to prevent liquid reflux caused by negative pressure. In a liquid cooling system, when the negative pressure inside the pipe is greater than that outside, the surrounding liquid may be sucked into the pipe, causing pollution or damage to the equipment. Therefore, measures need to be taken to prevent the occurrence of siphonage.

[0041] The test adopted a variety of anti-siphoning measures, including but not limited to high-pressure injection molding, the use of oil-resistant polyurethane AB glue, and the replacement of the board end with a crystal plug connection method with a waterproof design similar to aviation plugs, etc. These measures are intended to prevent the occurrence of siphoning through different mechanisms.

[0042] Capillary phenomenon refers to the phenomenon that liquid rises or falls in a thin tube. Its principle is related to the surface tension of the liquid and the adhesion of the tube wall to the liquid. In the immersion liquid cooling system, the capillary phenomenon may affect the flow and distribution of the liquid, so it is necessary to study it and eliminate the capillary phenomenon outside the wire.

[0043] Capillary phenomena are affected by many factors, including the properties of the liquid (such as surface tension, density, viscosity, etc.), the material and roughness of the pipe wall, temperature, and pipe diameter, etc. In the test, an inverted funnel-shaped SR is performed on the outside of the wire to block it.

[0044] Test equipment

[0045] Select appropriate test materials and equipment, build a test platform, and ensure that the test conditions meet the requirements.

[0046] Test operation

[0047] Operate according to the preset test plan, including liquid injection, temperature control, variable adjustment, etc. At the same time, record key data during the test, such as the height and time of liquid rise or fall.

[0048] Experimental Replication and Comparison

[0049] In order to ensure the reliability of the test results, it is necessary to repeat the test for the same set of test conditions many times and compare and analyze the test results under different conditions.

[0050] Data collection

[0051] During the test, the data of comparative experiments are collected regularly to collect and record key data in real time. These data include but are not limited to the height and time of liquid rise or fall.

[0052] Data analysis methods

[0053] The collected data were collated and analyzed, and by comparing and analyzing the test results under different conditions, the effects of anti-siphon and capillary phenomena on the immersion liquid cooling system and their optimization solutions were obtained.

[0054] Anti-siphon design optimization

[0055] The siphon phenomenon can be effectively prevented by improving the design of the jumper interface and adding anti-siphon structures. At the same time, anti-siphon materials are used to make the cable sheath to further reduce the risk of siphoning.

[0056] Capillary suppression measures

[0057] A special process is used to treat the inside of the cable to prevent coolant penetration; an inverted funnel-shaped SR is installed on the outside to reduce the capillary effect and prevent coolant from climbing. In addition, the coolant is replaced regularly to maintain its cleanliness to reduce the probability of capillary phenomena.

[0058] Improvement of test environment control and monitoring technology

[0059] The monitoring technology is improved by using the equivalent method, substitution method and other methods to ensure the accuracy of the test data. At the same time, the cable status is monitored periodically by regular monitoring to improve the accuracy of the test data.

[0060] Optimize the design of the immersion liquid-cooled network jumper to improve its anti-siphon and anti-capillary performance, change the connector matching form, and consider the change of protection method from both the board end and the wire end to achieve the anti-siphon and capillary effects. By preventing these two phenomena, the service life of the network jumper can be extended and the reliability of the entire liquid cooling system can be improved.

Refrigerant component analysis: Analyze the mainstream insulating cooling oil component and identify the cooling oil component; Wire base material screening: According to the cooling oil component, select a suitable base material and modify the base material; Wire base material testing: Test the selected base material and the modified base material Thermal aging life test; Wire base material selection: Combine test results, material cost, and processing methods to make a multi-dimensional selection and finally determine the wire base material material; Solve the siphon and capillary phenomena: Introduce a universal cooling oil cable for the terminal power distribution of the data center immersion liquid cooling system, design the terminal assembly to prevent siphoning, screen and replace materials to prevent capillary phenomena, and prepare a universal data center immersion liquid cooling system dedicated power harness, optimize the design of the immersion liquid cooling network jumper to improve its anti-siphon and anti-capillary performance, change the connector matching form, and consider the change of protection method from both the board end and the wire end to achieve the anti-siphon and capillary effects.
