Description

Technical Field

[0002] With the rapid development of informatization, the integration of communication equipment is getting higher and higher, and the configuration power density of servers is constantly increasing. Heat dissipation has become a problem. Many servers use liquid cooling systems for system heat dissipation. The use of liquid cooling systems is a problem for server liquid leakage. Once a leak occurs, it will directly affect the use of the server and the operation of the entire computer room server. In the related art, some servers use liquid cooling modules with a leak detection function for heat dissipation. The designed leak detection structure is simple, and it only alarms for leaks and feeds back to the server. Even if a liquid receiving structure is set to receive the leaked liquid, when there is a leak in the liquid cooling system, the switch valve on the liquid supply pipeline of the liquid cooling system is directly controlled to be closed, the server is shut down, and the leaked liquid received in the liquid receiving structure is discharged.

[0070] The liquid cooling equipment leakage detection device also includes a leakage detection control module 14 and a system control module 15, the leakage detection control module 14 is connected to the leakage detector 8, and the system control module 15 is connected to the switch valve 3, the pressure sensor 7, the drainage pump 9, the flow meter 10, the liquid level sensor 12 and the drainage valve 13.

[0071] In one embodiment, Figure 3 , Figure 4 As shown, a method for detecting leakage of a liquid cooling device is provided, and the method is applied to Figure 1 , Figure 2 The liquid cooling equipment leakage detection device in the example is used to illustrate, including the following steps:

[0072] S1, in response to the liquid cooling device being started, detecting whether there is liquid leakage in the heat exchange structure 4 through the liquid leakage sensor 5 of the heat exchange structure 4;

[0073] S2, in response to the presence of liquid leakage in the heat exchange structure 4, detecting whether there is liquid leakage in the liquid contact structure 6 by means of a pressure sensor 7 of the liquid contact structure 6 located below the heat exchange structure 4;

[0074] S3, in response to the presence of liquid leakage in the heat exchange structure 4, using the pressure signal value of the pressure sensor 7 of the liquid contact structure 6 to calculate and obtain the pressure calculation value of the liquid leakage in the liquid contact structure 6;

[0075] S4. In response to the pressure calculation value being less than or equal to a first threshold value, the speed of delivering coolant into the heat exchange structure 4 is controlled to remain unchanged; in response to the pressure calculation value being greater than a second threshold value, the delivery of coolant into the heat exchange structure 4 is stopped; in response to the pressure calculation value being greater than the first threshold value and less than or equal to the second threshold value, the speed of delivering coolant into the heat exchange structure 4 is controlled to be negatively correlated with the pressure calculation value.

[0076] Among them, when there is leakage in the heat exchange structure 4 and there is leakage in the liquid contacting structure 6, the pressure signal value of the pressure sensor 7 of the liquid contacting structure 6 is used to calculate the pressure calculation value of the leakage in the liquid contacting structure 6, and the speed of delivering coolant to the heat exchange structure 4 is controlled according to the size of the pressure calculation value. The server shutdown is not directly controlled, so as to avoid the server shutdown caused by micro-leakage, and to maintain the normal operation of the server when there is micro-leakage in the liquid cooling system.

[0077] In this embodiment, in response to the liquid cooling device being started, the step of detecting whether the heat exchange structure 4 has leakage by means of the liquid leakage sensor 5 of the heat exchange structure 4 comprises:

[0078] Detect whether the liquid leakage sensor 5 of the heat exchange structure 4 has a liquid leakage signal value;

[0079] In response to the leakage sensor 5 of the heat exchange structure 4 having a leakage signal value, it is determined again after multiple cycles of detection whether the leakage sensor 5 of the heat exchange structure 4 has a leakage signal value. If so, it is determined that the heat exchange structure 4 has leakage; otherwise, it is determined that the heat exchange structure 4 has no leakage.

[0080] Preferably, the number of cycle detections is three times, so that misjudgment of the leakage sensor 5 can be avoided through three cycle detections, and whether the heat exchange structure 4 is leaking can be accurately determined through multiple detections.

[0081] In this embodiment, in response to the presence of liquid leakage in the heat exchange structure 4, the step of detecting whether there is liquid leakage in the liquid contact structure 6 by means of a pressure sensor 7 of the liquid contact structure 6 located below the heat exchange structure 4 includes:

[0082] Detect whether the pressure sensor 7 of the liquid contact structure 6 located below the heat exchange structure 4 has a pressure signal value;

[0083] In response to a pressure signal value from any one of the pressure sensors 7 of the liquid contact structure 6 , it is determined that there is liquid leakage in the heat exchange structure 4 .

[0084] like Figure 2As shown, in order to facilitate the drainage of the leakage in the liquid contacting structure 6, a middle partition 61 is provided in the liquid contacting structure 6, and the middle partition 61 is arranged at an angle. A drainage hole is arranged at the low water level part of the middle partition 61, which will cause the heights of the multiple pressure sensors 7 to be different. Even if there is leakage in the liquid contacting structure 6, not all pressure sensors 7 can detect the leakage signal value. Therefore, if any pressure sensor 7 in the liquid contacting structure 6 has a pressure signal value, it is determined that there is leakage in the heat exchange structure 4, thereby improving the accuracy of leakage judgment.

[0085] In this embodiment, in response to the presence of liquid leakage in the heat exchange structure 4, the step of calculating and obtaining the pressure calculation value of the liquid leakage in the liquid contact structure 6 by using the pressure signal value of the pressure sensor 7 of the liquid contact structure 6 includes:

[0086] Read the pressure signal value of the pressure sensor 7 in the liquid contact structure 6, and set the pressure signal value p of the i-th pressure sensor 7 i , where i is an integer;

[0087] Obtain the average value of the pressure signal of the pressure sensor 7 of the liquid contact structure 6

[0088] Obtain the calculated pressure value of the leaked liquid in the liquid contact structure 6

[0089] Preferably, nine pressure sensors 7 are arranged in an array below the middle partition 61. In this way, the leakage signal value of each pressure sensor 7 may be different. Therefore, it is necessary to calculate the pressure calculation value of the leakage in the liquid contacting structure 6 as a whole. The pressure calculation value is used to measure the pressure of the leakage in the liquid contacting structure 6, thereby judging the amount of leakage in the liquid contacting structure 6.

[0090] If the pressure calculation value of the leakage in the liquid contact structure 6 is When K is a coefficient, 10≤K≤30, so it mainly depends on To obtain the pressure calculation value of the leakage in the liquid contact structure 6, the pressure calculation value has low sensitivity. would be equivalent to Increasing sensitivity increases control sensitivity.

[0091] In this embodiment, in response to the calculated pressure value being greater than a first threshold value and less than or equal to a second threshold value, controlling the speed of delivering coolant into the heat exchange structure 4 to be negatively correlated with the calculated pressure value includes:

[0092] The speed of delivering the coolant into the heat exchange structure 4 is controlled by the opening angle n of the switch valve 3;

[0093] Set the standard value p for judging the leakage amount 标 , the first threshold is the standard value p 标 a times, the second threshold is the standard value p 标 b times, where a<b;

[0094] In response to the calculated pressure value being greater than the first threshold value and less than or equal to the second threshold value, the opening angle n of the switch valve 3 is controlled to be The speed of conveying the coolant into the heat exchange structure 4 is controlled to be negatively correlated with the pressure calculation value.

[0095] Preferably, a is 10% and b is 80%. The first threshold value = p 标 *10%, second threshold = p 标 *85%, so in p 标 *10%<p≤p 标 * When 85%, the opening angle of the switch valve 3 is controlled to be The speed of delivering the coolant to the heat exchange structure 4 is controlled based on the amount of leakage.

[0096] When the calculated value is 10% lower than the standard value, the switch valve does not move and maintains the original state. When the calculated value is between 10%-85% of the standard value, the switch valve 3 uses the system control program to control the switching degree of the switch valve 3. When the calculated value exceeds 85% of the standard value, the switch valve 3 is directly closed. When the server is powered on again and there is no leakage signal, the switch valve 3 is reopened.

[0097] like Figure 4 As shown, in this embodiment, the method further includes:

[0098] In response to the presence of liquid leakage in the liquid contact structure 6, a wetted perimeter value of a liquid leakage detector 8 in the liquid contact structure 6 is obtained;

[0099] In response to the wetted perimeter value of the liquid leakage detector 8 in the liquid contact structure 6 being greater than a third threshold value, the liquid discharge pump 9 is started to discharge the leaked liquid in the liquid contact structure 6 into the liquid storage structure 11;

[0100] After the drainage pump 9 is started, the drainage flow rate is detected by the flow meter 10 on the drainage pipeline of the drainage pump 9, and the drainage pressure is detected by the pressure sensor 7 on the drainage pipeline of the drainage pump 9;

[0101] In response to the discharge flow being less than or equal to a flow threshold, and the discharge pressure being less than or equal to a pressure threshold, controlling the discharge pump 9 to stop;

[0102] After the liquid discharge pump 9 is started, the liquid level in the liquid storage structure 11 is detected by the liquid level sensor 12;

[0103] In response to the liquid level in the liquid storage structure 11 being higher than the first liquid level, opening the liquid discharge valve 13 of the liquid storage structure 11;

[0104] In response to the liquid level in the liquid storage structure 11 being lower than the second liquid level, closing the liquid discharge valve 13 of the liquid storage structure 11;

[0105] After the liquid displacement pump 9 stops, the heat exchange structure 4 is replaced, and the heat exchange structure 4 is controlled to be powered on again;

[0106] Detect whether the heat exchange structure 4 has leakage. If the heat exchange structure 4 does not have leakage, control the liquid cooling device to reset and restart.

[0107] Among them, the liquid storage structure 11 can buffer the leaked liquid. The leaked liquid is discharged only when the liquid level in the liquid storage structure 11 is higher than the first liquid level. The leaked liquid is not discharged when the liquid level in the liquid storage structure 11 is lower than the second liquid level, which is convenient for replacing the heat exchange structure 4.

[0108] Preferably, the third threshold is 70%, the flow threshold is 0, and the pressure threshold is 0. The drainage pump 9 is started to determine whether to start drainage according to the wet cycle value of the leakage detector 8. If the wet cycle value exceeds 70%, the drainage is started, and the drainage pump 9 discharges the liquid inside the liquid contact structure 6 into the liquid storage structure 11. The drainage pipeline is equipped with a flow meter 10 and a pressure sensor 7 to detect the flow and pressure of the drainage system. When the flow is close to zero and the pressure is close to zero, the drainage pump 9 stops working to prevent the drainage pump 9 from running dry. There is a liquid level sensor 12 inside the liquid storage structure 11 to judge the storage liquid situation. When the upper limit is reached, the drainage valve 13 is opened for drainage, and when the lower limit is reached, the drainage valve 13 is closed. The system leakage drainage protection is completed, and it is ensured that the leakage position does not affect the operation of servers at other locations. This method accurately judges the leakage situation and processes the liquid at the leakage position, protects the leakage server, and avoids the servers at other locations from not working properly due to the leakage.

[0109] In this embodiment, the method further includes:

[0110] In response to the presence of liquid leakage in the liquid contact structure 6, the duration from the shutdown of the liquid discharge pump 9 to the next startup is obtained, the increase in the amount of liquid leaking in the liquid contact structure 6 during the duration is obtained, and the leakage rate is obtained by dividing the increase in the amount of liquid by the duration;

[0111] In response to the leakage rate being greater than a preset leakage rate threshold, the drainage pump 9 is controlled to stop, and a warning message for replacing the heat exchange structure 4 is issued.

[0112] Among them, the leakage rate of the heat exchange structure 4 can be fed back through the leakage rate in the liquid contacting structure 6, and the availability of the heat exchange structure 4 can be timely evaluated. When the leakage rate is greater than the preset leakage rate threshold, the heat exchange structure 4 can be replaced in time to avoid serious leakage.

[0113] like Figure 4 As shown, in this embodiment, the method further includes:

[0114] In response to the presence of liquid leakage in the heat exchange structure 4, the liquid cooling device starts liquid leakage protection and monitors the magnitude of the pressure calculation value;

[0115] In response to the calculated pressure value being greater than a second threshold, the liquid cooling device is controlled to be powered off and shut down.

[0116] Among them, leakage sensors 5 and pressure sensors 7 are evenly distributed at each interface position of the heat exchange unit and at the bottom of the liquid receiving structure 11. The system detects leakage and leakage amount through the leakage sensor 4, and feeds back the feedback signal to the leakage detection control module 14. The leakage detection control module 14 sends a control command to the system control module 15 and the server control module. The system control module 15 and the server control module perform corresponding processing methods according to the feedback signal. The server control module performs server protection processing according to the feedback signal. If there is no leakage signal, the system operates normally and the server module does not take corresponding actions. If there is a leakage signal, the server module starts the leakage protection mechanism. The server control system is internally provided with a corresponding action protection mechanism for the leakage situation to perform server protection.

[0117] In the above-mentioned liquid cooling equipment leakage detection method, when there is leakage in the heat exchange structure 4 and there is leakage in the liquid contacting structure 6, the pressure signal value of the pressure sensor 7 of the liquid contacting structure 6 is used to calculate the pressure calculation value of the leakage in the liquid contacting structure 6, and the speed of delivering coolant to the heat exchange structure 4 is controlled according to the size of the pressure calculation value. The server shutdown is not directly controlled, so as to avoid the server shutdown caused by micro-leakage, and to maintain the normal operation of the server when there is micro-leakage in the liquid cooling system.

[0118] In one embodiment, Figure 1 , Figure 2As shown, a liquid cooling device leakage detection device is provided, which is used to implement the steps of the liquid cooling device leakage detection method described above; the liquid cooling device leakage detection device includes a liquid cooling liquid supply mechanism 1, a liquid supply pipeline 2, a switch valve 3, a heat exchange structure 4, a leakage sensor 5, a liquid contact structure 6 and a pressure sensor 7 and a system control module 15; the liquid cooling liquid supply mechanism 1 forms a cooling circuit with the heat exchange structure 4 through the liquid supply pipeline 2, the switch valve 3 is arranged on the liquid supply pipeline 2, the heat exchange structure 4 is used for liquid cooling the server heat exchange unit, the liquid contact structure 6 is arranged below the heat exchange structure 4, the leakage sensor 5 is arranged on the heat exchange structure 4, and at least two of the pressure sensors 7 are installed on the liquid contact structure 6 to obtain the pressure of the leakage in the liquid contact structure 6;
