Description

Technical Field

[0001] This application relates to the field of server liquid cooling technology, and in particular to a method, apparatus, computer equipment, and storage medium for detecting leakage in liquid cooling equipment. Background Technology

[0002] With the rapid development of information technology, communication equipment is becoming increasingly integrated, and the power density of servers is constantly rising, making heat dissipation a challenge. Many servers use liquid cooling systems for heat dissipation. However, liquid leakage in liquid cooling systems is a problem, as it directly affects server operation and the overall operation of the server room. Some servers use liquid cooling modules with leakage detection capabilities for heat dissipation. The designed leakage detection structure is simple, only providing an alarm and feedback to the server. Even with a catch-the-leak structure, if a leak is detected, the switch valve on the liquid cooling system's supply pipe is directly closed, the server shuts down, and the collected leakage is discharged. This means that even a minor leak can cause the server to malfunction, and it cannot maintain normal server operation when a minor leak exists in the liquid cooling system. Summary of the Invention

[0003] Based on this, a method, apparatus, computer equipment, and storage medium for detecting leakage in liquid cooling equipment are provided to solve the technical problem that directly controlling the shut-off valve on the liquid cooling system supply pipeline to close when there is a leakage in the liquid cooling system, causing the server to shut down, cannot maintain normal server operation when there is a minor leakage in the liquid cooling system.

[0004] On the one hand, a method for detecting leakage in a liquid cooling device is provided, the method comprising:

[0005] In response to the start-up of the liquid cooling equipment, a leakage sensor on the heat exchange structure is used to detect whether there is leakage in the heat exchange structure.

[0006] In response to leakage in the heat exchange structure, a pressure sensor located in the liquid-contacting structure below the heat exchange structure is used to detect whether there is leakage in the liquid-contacting structure.

[0007] In response to leakage within the heat exchange structure, the pressure value of the leakage within the liquid-contacting structure is calculated using the pressure signal value of the pressure sensor of the liquid-contacting structure.

[0008] In response to the calculated pressure value being less than or equal to a first threshold, the rate at which coolant is delivered into the heat exchange structure is kept constant.

[0009] In response to the calculated pressure value being greater than the second threshold, the supply of coolant to the heat exchange structure is stopped.

[0010] In response to the calculated pressure value being greater than a first threshold and less than or equal to a second threshold, the rate at which coolant is delivered into the heat exchange structure is controlled to be negatively correlated with the calculated pressure value.

[0011] In one embodiment, the step of detecting whether there is a leak in the heat exchange structure via a leak sensor in response to the start of the liquid cooling device includes:

[0012] The leak sensor of the heat exchange structure is detected to check for leak signals.

[0013] In response to the leakage sensor of the heat exchange structure having a leakage signal value, after multiple loop detections, it is determined again whether the leakage sensor of the heat exchange structure has a leakage signal value. If it does, it is determined that the heat exchange structure has leakage; otherwise, it is determined that the heat exchange structure does not leak.

[0014] In one embodiment, the step of detecting whether there is leakage in the liquid-contacting structure via a pressure sensor located in the liquid-contacting structure below the heat exchange structure in response to leakage includes:

[0015] The pressure sensor located on the liquid-contact structure below the heat exchange structure is checked for pressure signal value.

[0016] If any pressure sensor in the liquid-contacting structure has a pressure signal value, it is determined that there is a leak in the heat exchange structure.

[0024] In response to the calculated pressure value being greater than a first threshold and less than or equal to a second threshold, the opening angle n of the switching valve is controlled to be... The rate at which coolant is delivered into the heat exchange structure is negatively correlated with the calculated pressure value.

[0025] In one embodiment, the method further includes:

[0026] In response to the presence of leakage within the liquid-contacting structure, the wetted perimeter value of the leakage detector within the liquid-contacting structure is obtained;

[0027] If the wetted perimeter value of the leak detector in the liquid-contacting structure is greater than the third threshold, the drain pump is activated to drain the leaked liquid in the liquid-contacting structure into the liquid storage structure.

[0028] After the drainage pump is started, the drainage flow rate is detected by the flow meter on the drainage pipeline of the drainage pump, and the drainage pressure is detected by the pressure sensor on the drainage pipeline of the drainage pump.

[0029] In response to the discharge flow rate being less than or equal to a flow rate threshold and the discharge pressure being less than or equal to a pressure threshold, the discharge pump is controlled to stop.

[0030] After the drainage pump is started, the liquid level in the liquid storage structure is detected by the liquid level sensor;

[0031] The drain valve of the liquid storage structure is opened in response to the liquid level in the liquid storage structure being higher than the first liquid level.

[0032] The drain valve of the liquid storage structure is closed in response to the liquid level in the liquid storage structure being lower than the second liquid level.

[0033] After the drainage pump stops, replace the heat exchange structure and control the heat exchange structure to be powered on again;

[0034] The system detects whether there is any leakage in the heat exchange structure. If there is no leakage, the system controls the liquid cooling equipment to reset and restart.

[0035] In one embodiment, the method further includes:

[0036] In response to leakage within the heat exchange structure, the liquid cooling device activates leakage protection and monitors the calculated pressure value.

[0038] On the other hand, a liquid cooling equipment leakage detection device is provided, which includes a liquid cooling supply mechanism, a supply pipeline, a switching valve, a heat exchange structure, a leakage sensor, a liquid receiving structure, a pressure sensor, and a system control module.

[0039] The liquid cooling supply mechanism forms a cooling circuit with the heat exchange structure through the liquid supply pipe. The switch valve is installed on the liquid supply pipe. The heat exchange structure is used to liquid cool the server heat exchange unit. The liquid receiving structure is located below the heat exchange structure. The leakage sensor is located on the heat exchange structure. At least two pressure sensors are installed on the liquid receiving structure to obtain the pressure of leakage in the liquid receiving structure.

[0040] The leakage sensor of the heat exchange structure is used to detect whether there is leakage in the heat exchange structure when the liquid cooling equipment is started.

[0041] The pressure sensor of the liquid-contacting structure is used to detect whether there is leakage in the liquid-contacting structure when there is leakage in the heat exchange structure.

[0042] The system control module is used to calculate the pressure value of the leaking liquid in the liquid-contacting structure by using the pressure signal value of the pressure sensor of the liquid-contacting structure when there is leakage in the liquid-contacting structure; in response to the pressure calculation value being less than or equal to a first threshold, control the speed of supplying coolant to the heat exchange structure to remain unchanged; in response to the pressure calculation value being greater than a second threshold, stop supplying coolant to the heat exchange structure; and in response to the pressure calculation value being greater than the first threshold and less than or equal to the second threshold, control the speed of supplying coolant to the heat exchange structure to be negatively correlated with the pressure calculation value.

[0043] In another aspect, a computer device is provided, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to perform the following steps:

[0044] In response to the start-up of the liquid cooling equipment, a leakage sensor on the heat exchange structure is used to detect whether there is leakage in the heat exchange structure.

[0045] In response to leakage in the heat exchange structure, a pressure sensor located in the liquid-contacting structure below the heat exchange structure is used to detect whether there is leakage in the liquid-contacting structure.

[0046] In response to leakage within the heat exchange structure, the pressure value of the leakage within the liquid-contacting structure is calculated using the pressure signal value of the pressure sensor of the liquid-contacting structure.

[0047] In response to the calculated pressure value being less than or equal to a first threshold, the rate at which coolant is delivered into the heat exchange structure is kept constant.

[0048] In response to the calculated pressure value being greater than the second threshold, the supply of coolant to the heat exchange structure is stopped.

[0049] In response to the calculated pressure value being greater than a first threshold and less than or equal to a second threshold, the rate at which coolant is delivered into the heat exchange structure is controlled to be negatively correlated with the calculated pressure value.

[0050] In another aspect, a computer-readable storage medium is provided having a computer program stored thereon, which, when executed by a processor, performs the following steps:

[0052] In response to leakage in the heat exchange structure, a pressure sensor located in the liquid-contacting structure below the heat exchange structure is used to detect whether there is leakage in the liquid-contacting structure.

[0053] In response to leakage within the heat exchange structure, the pressure value of the leakage within the liquid-contacting structure is calculated using the pressure signal value of the pressure sensor of the liquid-contacting structure.

[0054] In response to the calculated pressure value being less than or equal to a first threshold, the rate at which coolant is delivered into the heat exchange structure is kept constant.

[0055] In response to the calculated pressure value being greater than the second threshold, the supply of coolant to the heat exchange structure is stopped.

[0056] In response to the calculated pressure value being greater than a first threshold and less than or equal to a second threshold, the rate at which coolant is delivered into the heat exchange structure is controlled to be negatively correlated with the calculated pressure value.

[0057] The aforementioned liquid cooling equipment leakage detection method, device, computer equipment, and storage medium calculate the pressure value of the leaking liquid in the liquid-contacting structure by using the pressure signal value of the pressure sensor in the liquid-contacting structure when there is leakage in both the heat exchange structure and the liquid-contacting structure. The speed at which coolant is delivered to the heat exchange structure is controlled based on the magnitude of the calculated pressure value, without directly controlling the server to shut down. This avoids server shutdown due to micro-leakage and ensures that the server continues to operate normally when there is micro-leakage in the liquid cooling system. Attached Figure Description

[0066] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0067] The liquid cooling equipment leakage detection method provided in this application can be applied to, for example... Figure 1 , Figure 2 In the application environment shown, the liquid cooling equipment leakage detection device includes a liquid cooling supply mechanism 1, a supply pipe 2, a switching valve 3, a heat exchange structure 4, a leakage sensor 5, a liquid receiving structure 6, and a pressure sensor 7. The liquid cooling supply mechanism 1 forms a cooling circuit with the heat exchange structure 4 through the supply pipe 2. The switching valve 3 is installed on the supply pipe 2. The heat exchange structure 4 is used for liquid cooling of the server heat exchange unit. The liquid receiving structure 6 is located below the heat exchange structure 4. The leakage sensor 5 is located on the heat exchange structure 4. At least two pressure sensors 7 are installed on the liquid receiving structure 6 to obtain the pressure of leakage within the liquid receiving structure 6.

[0068] like Figure 2 As shown, the liquid receiving structure 6 is provided with a middle partition 61, at least two pressure sensors 7 are provided below the middle partition 61, and a drain hole is provided at the low water level part of the middle partition 61.

[0069] The liquid cooling equipment leakage detection device further includes a leakage detector 8, a drain pump 9, a flow meter 10, a liquid storage structure 11, a liquid level sensor 12, and a drain valve 13. The leakage detector 8 is located inside the liquid receiving structure 6 and is used to detect the wetted perimeter value. The drain pump 9 is connected to the liquid receiving structure 6. The drain pipe of the drain pump 9 is equipped with the flow meter 10 and the pressure sensor 7. The flow meter 10 is used to measure the drain flow rate of the drain pump 9. The drain pump 9 is connected to the liquid storage structure 11. The liquid storage structure 11 is equipped with the liquid level sensor 12, which is used to detect the liquid level inside the liquid storage structure 11. The drain valve 13 is located at the bottom of the liquid storage structure 11 and is connected to the liquid cooling supply mechanism 1 and / or the heat exchange structure 4.

[0070] The liquid cooling equipment leakage detection device further 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 drain pump 9, the flow meter 10, the liquid level sensor 12, and the drain valve 13.

[0071] In one embodiment, such as Figure 3 , Figure 4 As shown, a method for detecting leakage in liquid cooling equipment is provided, which can be applied to... Figure 1 , Figure 2 Taking a liquid cooling equipment leak detection device as an example, the following steps are included:

[0072] S1. In response to the start of the liquid cooling equipment, the leakage sensor 5 of the heat exchange structure 4 is used to detect whether there is leakage in the heat exchange structure 4;

[0073] S2. In response to the presence of leakage in the heat exchange structure 4, the pressure sensor 7 located in the liquid receiving structure 6 below the heat exchange structure 4 is used to detect whether there is leakage in the liquid receiving structure 6.

[0074] S3. In response to the presence of leakage in the heat exchange structure 4, the pressure value of the leakage in the liquid receiving structure 6 is calculated using the pressure signal value of the pressure sensor 7 of the liquid receiving structure 6.

[0075] S4. In response to the calculated pressure value being less than or equal to a first threshold, the rate at which coolant is supplied to the heat exchange structure 4 is kept constant; in response to the calculated pressure value being greater than a second threshold, the supply of coolant to the heat exchange structure 4 is stopped; in response to the calculated pressure value being greater than the first threshold and less than or equal to the second threshold, the rate at which coolant is supplied to the heat exchange structure 4 is controlled to be negatively correlated with the calculated pressure value.

[0076] Specifically, when there is leakage in both the heat exchange structure 4 and the liquid receiving structure 6, the pressure signal value of the pressure sensor 7 in the liquid receiving structure 6 is used to calculate the pressure value of the leakage in the liquid receiving structure 6. The speed at which coolant is delivered to the heat exchange structure 4 is controlled based on the magnitude of the pressure value, without directly controlling the server to shut down. This avoids server shutdown due to micro-leakage and ensures that the server continues to operate normally when there is micro-leakage in the liquid cooling system.

[0077] In this embodiment, the step of detecting whether there is leakage in the heat exchange structure 4 via the leakage sensor 5 in response to the start of the liquid cooling device includes:

[0078] The leak sensor 5 of the heat exchange structure 4 is used to detect whether there is a leak signal value.

[0079] If the leakage sensor 5 of the heat exchange structure 4 has a leakage signal value, the system will check again after multiple cycles of detection to see if the leakage sensor 5 of the heat exchange structure 4 has a leakage signal value. If it does, the system will determine that the heat exchange structure 4 is leaking; otherwise, the system will determine that the heat exchange structure 4 is not leaking.

[0080] Preferably, the number of cyclic detections is three. This can avoid false judgments by the leakage sensor 5 through three cyclic detections, and can accurately determine whether the heat exchange structure 4 is leaking through multiple detections.

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

[0082] The pressure sensor 7 located on the liquid-contacting structure 6 below the heat exchange structure 4 is checked for pressure signal value.

[0083] If any pressure sensor 7 of the liquid-receiving structure 6 has a pressure signal value, it is determined that there is a leak in the heat exchange structure 4.

[0084] like Figure 2As shown, to facilitate the drainage of leaks within the liquid receiving structure 6, a middle partition 61 is provided in the liquid receiving structure 6. The middle partition 61 is inclined, and a drain hole is provided at the low water level of the middle partition 61. This results in the different heights of the multiple pressure sensors 7. Even if there is a leak within the liquid receiving structure 6, not all pressure sensors 7 will detect a leak signal value. Therefore, if any pressure sensor 7 in the liquid receiving structure 6 has a pressure signal value, it is determined that there is a leak within the heat exchange structure 4, thus improving the accuracy of leak detection.

[0085] In this embodiment, the step of calculating the pressure value of the leak in the liquid receiving structure 6 in response to the presence of leakage in the heat exchange structure 4 includes:

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

[0087] The average pressure signal of the pressure sensor 7 of the liquid-contact structure 6 is obtained. ;

[0088] Obtain the calculated pressure value of leakage within the liquid-contacting structure 6. .

[0089] Preferably, nine pressure sensors 7 are arrayed below the intermediate partition 61. Since the leakage signal value of each pressure sensor 7 may be different, it is necessary to calculate the overall leakage pressure value in the liquid receiving structure 6. The calculated pressure value is used to measure the magnitude of the leakage pressure in the liquid receiving structure 6, thereby determining the amount of leakage in the liquid receiving structure 6.

[0090] The calculated pressure value if the liquid leakage occurs within the liquid-contacting structure 6 When K is a coefficient, 10 ≤ K ≤ 30, thus mainly relying on To obtain the pressure value of leakage within the liquid-contacting structure 6, the pressure calculation value has low sensitivity. If the pressure value of leakage within the liquid-contacting structure 6 is... Then it would be equivalent to Increasing sensitivity increases the control sensitivity.

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

[0092] The speed at which coolant is delivered into the heat exchange structure 4 is controlled by the opening angle n of the switching valve 3.

[0093] Set a standard value for determining the amount of leakage. The first threshold is the standard value. a times, the second threshold is the standard value. b times, where a < b;

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

[0095] Preferably, a is 10% and b is 85%. First threshold = *10%, second threshold = *85%, thus in *10%<p≤ At 85%, the opening angle of the switching valve 3 is controlled as follows: The rate at which coolant is delivered into 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 its original state. When the calculated value is between 10% and 85% of the standard value, the switch valve 3 uses the system control program to control the opening and closing degree of the switch valve 3. When the calculated value exceeds 85% of the standard value, the switch valve 3 is directly closed. The server is powered on again and there is no leakage signal, and the switch valve 3 is reopened.

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

[0098] In response to leakage within the liquid-contacting structure 6, the wetted perimeter value of the leakage detector 8 within the liquid-contacting structure 6 is obtained;

[0099] In response to the wetted perimeter value of the leak detector 8 in the liquid receiving structure 6 being greater than the third threshold, the drain pump 9 is activated to drain the leaked liquid in the liquid receiving 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 rate being less than or equal to a flow rate threshold and the discharge pressure being less than or equal to a pressure threshold, the discharge pump 9 is controlled to stop.

[0102] After the drainage 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, the drain valve 13 of the liquid storage structure 11 is opened;

[0104] If the liquid level in the liquid storage structure 11 is lower than the second liquid level, the drain valve 13 of the liquid storage structure 11 is closed.

[0105] After the drainage pump 9 stops, the heat exchange structure 4 is replaced and the heat exchange structure 4 is powered on again.

[0106] The system detects whether there is any leakage in the heat exchange structure 4. If there is no leakage in the heat exchange structure 4, the system controls the liquid cooling device to reset and restart.

[0107] The liquid storage structure 11 can buffer leakage. Leakage is only discharged when the liquid level in the liquid storage structure 11 is higher than the first liquid level, and leakage is not discharged when the liquid level in the liquid storage structure 11 is lower than the second liquid level, which facilitates the replacement of the heat exchange structure 4.

[0108] Preferably, the third threshold is 70%, the flow threshold is 0, and the pressure threshold is 0. The drain pump 9 starts based on the wetted area value of the leak detector 8 to determine whether to initiate draining. If the wetted area value exceeds 70%, draining begins, and the drain pump 9 discharges the liquid inside the receiving structure 6 into the storage structure 11. A flow meter 10 and a pressure sensor 7 are installed on the drain pipeline to detect the flow rate and pressure of the draining system. When the flow rate and pressure approach zero, the drain pump 9 stops working to prevent it from running dry. The storage structure 11 has a level sensor 12 to determine the level of stored liquid. If the upper limit is reached, the drain valve 13 is opened to drain the liquid; if the lower limit is reached, the drain valve 13 is closed. This completes the system's leak drainage protection and ensures that the leak location does not affect the operation of other location servers. This method accurately determines the leak situation and handles the liquid at the leak location, providing leak server protection and preventing other location servers from malfunctioning due to leaks.

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

[0110] In response to leakage within the liquid receiving structure 6, the time from the shutdown of the drain pump 9 to its next startup is obtained, the increase in liquid leakage within the liquid receiving structure 6 during the time is obtained, and the leakage rate is obtained by dividing the increase in liquid by the time.

[0111] When the leakage rate exceeds a preset leakage rate threshold, the drain pump 9 is stopped and a warning message is issued to replace the heat exchange structure 4.

[0112] The leakage rate within the liquid receiving structure 6 can be used to feedback the leakage rate of the heat exchange structure 4, allowing for timely assessment of the availability of the heat exchange structure 4. When the leakage rate exceeds a preset leakage rate threshold, the heat exchange structure 4 can be replaced promptly to prevent severe leakage.

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

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

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

[0116] Leakage sensors 5 and pressure sensors 7 are evenly distributed at each interface of the heat exchange unit and at the bottom of the liquid-receiving structure 11. The system uses leakage sensors 4 to detect leakage and the amount of leakage, and sends feedback signals to the leakage detection control module 14. The leakage detection control module 14 issues control commands to the system control module 15 and the server control module. The system control module 15 and the server control module process the feedback signals accordingly. The server control module performs server protection processing based on the feedback signals. If there is no leakage signal, the system operates normally and the server module does not take any action. If there is a leakage signal, the server module activates the leakage protection mechanism. The server control system has an internal protection mechanism for leakage situations to protect the server.

[0117] In the above-mentioned liquid cooling equipment leakage detection method, when there is leakage in the heat exchange structure 4 and leakage in the liquid receiving structure 6, the pressure signal value of the pressure sensor 7 of the liquid receiving structure 6 is used to calculate the pressure value of the leakage in the liquid receiving structure 6. The speed of supplying coolant to the heat exchange structure 4 is controlled according to the magnitude of the pressure calculation value, without directly controlling the server to shut down, thus avoiding server shutdown in the event of a micro-leak and ensuring normal server operation when there is a micro-leak in the liquid cooling system.

[0118] In one embodiment, such as Figure 1 , Figure 2As shown, a liquid cooling equipment leakage detection device is provided to implement the steps of the liquid cooling equipment leakage detection method described above. The liquid cooling equipment leakage detection device includes a liquid cooling supply mechanism 1, a supply pipe 2, a switching valve 3, a heat exchange structure 4, a leakage sensor 5, a liquid receiving structure 6, a pressure sensor 7, and a system control module 15. The liquid cooling supply mechanism 1 forms a cooling circuit with the heat exchange structure 4 through the supply pipe 2. The switching valve 3 is installed on the supply pipe 2. The heat exchange structure 4 is used to liquid cool the server heat exchange unit. The liquid receiving structure 6 is located below the heat exchange structure 4. The leakage sensor 5 is located on the heat exchange structure 4. At least two pressure sensors 7 are installed on the liquid receiving structure 6 to obtain the pressure of the leakage in the liquid receiving structure 6.

[0119] The leakage sensor of the heat exchange structure 4 is used to detect whether there is leakage in the heat exchange structure 4 when the liquid cooling equipment is started.

[0120] The pressure sensor of the liquid-contacting structure 6 is used to detect whether there is leakage in the liquid-contacting structure 6 when there is leakage in the heat exchange structure.

[0121] The system control module 15 is used to calculate the pressure value of the leaking liquid in the liquid-contacting structure 6 by using the pressure signal value of the pressure sensor of the liquid-contacting structure 6 when there is leakage in the liquid-contacting structure 6; in response to the pressure calculation value being less than or equal to a first threshold, control the speed of supplying coolant to the heat exchange structure 4 to remain unchanged; in response to the pressure calculation value being greater than a second threshold, stop supplying coolant to the heat exchange structure 4; in response to the pressure calculation value being greater than the first threshold and less than or equal to the second threshold, control the speed of supplying coolant to the heat exchange structure 4 to be negatively correlated with the pressure calculation value.

[0122] like Figure 2 As shown, the liquid receiving structure 6 is provided with a middle partition 61, and at least two pressure sensors 7 are arranged below the middle partition 61.
