[0001] The present invention relates to the technical field of servers, and in particular to a server liquid cooling method. Background Art

[0002] As the requirements for server performance continue to increase, server heat dissipation has become a key and difficult issue. Due to the complex structure of the server system, conventional air cooling can no longer meet its heat dissipation needs. Liquid cooling solutions have better heat dissipation performance than air cooling solutions.

[0003] In existing liquid cooling, the cooling pipelines often work at full load and cannot be adjusted according to the server status. The cooling efficiency is poor and it also brings a heavy load to the circuit of the computer room, consumes a lot of energy, and there is a risk of circuit overload, which is not conducive to the normal operation of the server. Summary of the invention

[0006] Set the cooling temperature threshold T and cooling temperature standard value T S , cooling line fluid pressure threshold value P, cooling line fluid pressure standard value P S And turbine flow threshold L, turbine flow standard value L S ;

[0007] The sensor detects the first pipeline temperature T1 in real time;

[0042] The object of the present invention is to provide a server liquid cooling method for improving the cooling efficiency of a cooling system and achieving energy-saving effects.

[0043] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0044] like Figure 1 , Figure 2 As shown, the present invention provides a server liquid cooling method, which is applied to a server liquid cooling system. The server liquid cooling system includes: a first pipeline 1, the first pipeline 1 includes at least two pump bodies, and the first pipeline 1 is normally open; a second pipeline 2, the second pipeline 2 is normally closed, and is used to assist the first pipeline 1 in cooling and to adjust the pipeline fluid pressure and flow. The server liquid cooling method includes the following steps:

[0045] Set the cooling temperature threshold T and cooling temperature standard value T S , cooling line fluid pressure threshold value P, cooling line fluid pressure standard value P S And turbine flow threshold L, turbine flow standard value L S ;

[0046] The sensor detects the temperature T1 of the first pipeline 1 in real time;

[0047] The control system compares T1 with T. If T1 < T, the first pipeline 1 is kept running; if T1 > T, the first pipeline 1 is kept running while the second pipeline 2 is run.

[0048] When T1<T S When the second pipeline 2 is stopped;

[0049] The sensor detects the fluid pressure P1 of the first pipeline 1 in real time;

[0050] The control system records the special point P2 of fluid pressure;

[0051] The control system maintains normal pipeline fluid pressure;

[0052] Real-time detection of turbine flow L1 of the first pipeline 1;

[0053] The control system compares L1 and L. If L1 < L S , then check whether the main pump body in the first pipeline 1 is operating normally. If the main pump body is abnormal, the auxiliary pump body is operated at the same time; if L1>L, part of the second pipeline 2 is opened;

[0054] When L1=L S When , close the second pipeline 2;

[0055] Among them, T>T S , P>P S , L>L S .

[0056] Through at least two pump bodies, one is used as the main pump body and is always running, and the other pump bodies are used as auxiliary pump bodies. The auxiliary pump bodies are kept normally closed, and the second pipeline 2 assists the first pipeline 1 in liquid cooling. The second pipeline 2 is normally closed to achieve the effect of adjusting the liquid cooling system according to the server status and saving energy. When the temperature T1 of the first pipeline 1 exceeds the cooling temperature threshold T, the second pipeline 2 is opened and the auxiliary pump is operated to assist the liquid cooling of the first pipeline 1. Detect the fluid pressure P1 of the first pipeline 1 and record the special point P2 of the fluid pressure as the basis for the control system to open the second pipeline 2 to adjust the fluid pressure, so as to maintain the normal fluid pressure of the entire pipeline. Under normal circumstances, running the main pump body alone can maintain the turbine flow L1 of the first pipeline 1 at a normal value, that is, L S <L1<L, so when the turbine flow L1 of the first pipeline 1 is less than the turbine flow standard value L S When the turbine flow L1 of the first pipeline 1 is greater than the turbine flow threshold L, the control system opens the second pipeline 2 to shunt the flow to maintain normal turbine flow.

[0057] The control system compares L1 with L, and specifically includes: if L1=0, the main pump body is stopped and the auxiliary pump body is operated.

[0058] Optionally, there may be one or more auxiliary pump bodies, and the auxiliary pump bodies are connected in parallel with the main pump body.

[0059] When L1=0, the main pump body is judged to be completely damaged, and the control system shuts down the main pump body in time to avoid unnecessary energy consumption.

[0060] The control system maintains the normal fluid pressure in the pipeline, specifically including: the control system opens the second pipeline 2 in the time period when the special fluid pressure point P2 appears according to the recorded time when the special fluid pressure point P2 appears; compares the fluid pressure P1 of the first pipeline 1 with the standard value P of the fluid pressure of the cooling pipeline S size.

[0061] Specifically, the time period in which the special fluid pressure points P2 appear in large numbers can be obtained by counting the number of times the special fluid pressure points P2 appear in hours and selecting the time period in which the most special fluid pressure points P2 appear.

[0062] In order to avoid high-frequency opening and closing of the valves related to the second pipeline 2 when maintaining the pipeline fluid pressure, the second pipeline 2 is set to open during the period when the pipeline fluid pressure fluctuates greatly, that is, when the special fluid pressure point P2 appears more concentrated, so as to achieve the purpose of regulating the pipeline fluid pressure. The fluid pressure P1 of the first pipeline 1 is compared with the standard value P of the cooling pipeline fluid pressure. S The size of the fluid pressure P1 in the first pipeline 1 is detected.

[0063] The server liquid cooling system also includes: a heat exchanger 3; a liquid storage tank 4, which is connected to the heat exchanger 3 by a pipeline; a first pipeline 1 connects the pump body and the heat exchanger 3; the second pipeline 2 includes an auxiliary pipeline 21, and the starting end and the end of the second pipeline 2 are both connected to the heat exchanger 3; if T1>T, the first pipeline 1 is kept running and the second pipeline 2 is run at the same time, specifically including: at least two pump bodies in the first pipeline 1 work at the same time, the second pipeline 2 is partially opened, and the valve of the auxiliary pipeline 21 remains closed.

[0064] When the temperature of the first pipeline 1 is higher than the cooling temperature threshold, the auxiliary pump body is started, the main pump body and the auxiliary pump body run at the same time, and the second pipeline 2 is opened to enhance the liquid cooling effect on the server. The valve of the auxiliary pipeline 21 remains closed to keep the fluid pressure in the pipeline and the pipeline turbine flow stable.

[0065] like Figure 3 As shown, the first pipeline 1 includes: a first liquid supply pipe 11 and a first liquid return pipe 12. One end of the first liquid supply pipe 11 is connected to the pump body; one end of the first liquid return pipe 12 is connected to the heat exchanger 3; the sensor detects the fluid pressure P1 of the first pipeline 1 in real time, including: the sensor detects the pipeline fluid pressure P1 at the first liquid return pipe 12 in real time; the control system records the special point P2 of fluid pressure, including: the control system compares the size of P1 and P, if P1>P, it is judged as the special point P2 of fluid pressure and records the appearance time of the special point P2 of fluid pressure; if P1<P, it is judged as a normal point.

[0066] Realize the determination and recording of the special point P2 of fluid pressure.

[0067] like Figure 4 As shown, the second pipeline 2 includes: a second liquid supply pipe 22 and a second liquid return pipe 23. One end of the second liquid supply pipe 22 is connected to the heat exchanger 3; one end of the second liquid return pipe 23 is connected to the heat exchanger 3; the auxiliary pipeline 21 connects the second liquid supply pipe 22 and the second liquid return pipe 23; the control system maintains the normal pressure of the pipeline fluid includes: the control system opens the second liquid supply pipe 22, the second liquid return pipe 23 and the auxiliary pipeline 21 in the time period when the special fluid pressure point P2 appears according to the recorded time when the special fluid pressure point P2 appears.

[0068] Among them, a valve is provided on the auxiliary pipeline 21, and the control system can control the opening and closing angle of the valve.

[0069] The second liquid supply pipe 22, the auxiliary pipeline 21 and the second liquid return pipe 23 form a pipeline loop, so that the coolant is diverted through the auxiliary pipeline 21 to achieve the purpose of regulating the pipeline fluid pressure.

[0070] Compare the first pipeline 1 fluid pressure P1 with the cooling pipeline fluid pressure standard value P S The size of P1=P S When the control system closes the second liquid supply pipe 22, the second liquid return pipe 23 and the auxiliary pipeline 21.

[0071] If P1=P S When the server liquid cooling system is still in the time period where the special fluid pressure point P2 appears, the control system will not open the pipeline loop composed of the second liquid supply pipe 22, the auxiliary pipeline 21 and the second liquid return pipe 23 again.

[0072] When the fluid pressure P1 of the first pipeline 1 returns to the standard value, the second liquid supply pipe 22, the auxiliary pipeline 21 and the second liquid return pipe 23 are closed to form a pipeline loop to prevent the fluid pressure of the first pipeline 1 from being too low or the pump body from overloading to maintain the pipeline fluid pressure.

[0073] The server liquid cooling system also includes: a first outer tube and a second outer tube. The first outer tube connects the first liquid supply tube 11 and the first liquid return tube 12; the second outer tube connects the second liquid supply tube 22 and the second liquid return tube 23; real-time detection of the turbine flow L1 of the first pipeline includes: detecting the turbine flow L1 of the first outer tube; if L1>L, opening part of the second pipeline 2 includes: opening the valve of the auxiliary pipeline 21, and detecting the change of the turbine flow L1 of the first outer tube, if L1 does not change or increases, then opening the valve of the second outer tube.

[0074] The second outer pipe has a longer stroke than the auxiliary pipe 21 .

[0075] The first outer tube and the second outer tube pass through the server components to achieve a liquid cooling effect on the server. The turbine flow at the first outer tube is relatively stable and accurate. The auxiliary pipeline 21 is opened when the turbine flow of the first outer tube is too large to divert the flow. If the turbine flow of the first outer tube does not show a downward trend after the auxiliary pipeline 21 is opened, it is determined that the auxiliary pipeline 21 is faulty, and the second outer tube is opened to achieve a diversion effect.

[0076] The sensor detects the temperature T1 of the first pipeline 1 in real time, specifically including: the sensor detects the pipeline temperature T1 of the first liquid return pipe 12 in real time.

[0077] The cooling liquid passes through the first liquid supply pipe 11 and the first outer pipe. After cooling the server, the cooling liquid temperature increases and flows back into the first liquid return pipe 12. The cooling liquid temperature at the first liquid return pipe 12 can accurately reflect the temperature status of the components in the server.

[0078] The server liquid cooling method also includes: a fault alarm, when both the main pump body and the auxiliary pump body fail to work, the control system alarms.

[0079] Specifically, when the auxiliary pump is running, the turbine flow rate L1 of the first pipeline 1 is less than the turbine flow rate standard value L S When the auxiliary pump fails, the control system determines that the auxiliary pump is faulty.

[0080] After determining that the auxiliary pump body is faulty, the control system should promptly shut down the auxiliary pump body, close the second outer pipe valve and the auxiliary pipeline 21 valve to prevent the second pipeline 2 liquid from reflux and leaking during the maintenance process, and alarm to facilitate manual maintenance in a timely manner.

[0081] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
