Description

Technical Field

[0001] The present invention relates to the technical field of liquid cooling devices, and in particular to a liquid cooling device supporting automatic liquid injection. Background Art

[0002] In the current technological context, as the performance of electronic devices continues to improve, their heat generation also increases, which puts higher demands on cooling technology. Traditional air cooling methods are gradually unable to meet the cooling needs of modern electronic devices due to their low cooling efficiency and high noise. Therefore, liquid cooling technology has become an increasingly popular solution due to its excellent thermal conductivity and low noise level.

[0003] Liquid cooling systems transfer heat from heat sources to cooling devices (such as water cooling radiators) through fluid circulation, and then dissipate the heat to the outside through radiators, thereby achieving the purpose of reducing the temperature of the equipment. However, existing liquid cooling systems have some shortcomings. For example, the liquid in the system may decrease due to evaporation over time, resulting in reduced cooling efficiency; at the same time, gas may accumulate inside the system, affecting the circulation efficiency of the fluid.

[0004] In Chinese patent application 202111495914.6, an operation and maintenance test device for liquid-cooled electronic equipment is disclosed, which is installed on the liquid-cooled electronic equipment. The operation and maintenance test device includes a liquid supply unit, and the first liquid outlet of the liquid supply unit is connected to the liquid inlet of the liquid-cooled electronic equipment through a liquid supply pipeline, and the first liquid inlet of the liquid supply unit is connected to the liquid outlet of the liquid-cooled electronic equipment through a first return liquid pipeline, and the liquid inlet of the liquid-cooled electronic equipment is also connected to the charging unit through the air intake pipeline of the operation and maintenance test device, and the charging unit is used to inflate the liquid-cooled electronic equipment when the liquid supply pipeline is closed, so that the coolant is discharged from the liquid-cooled electronic equipment; thereby, the operating environment of the liquid-cooled electronic equipment can be guaranteed when performing multiple mode tests on the liquid-cooled electronic equipment, which solves the technical problem of high cost and low efficiency caused by the need to use different tools for different testing tasks of the liquid-cooled electronic equipment in the prior art. The structure is simple, the cost is low, and the test work efficiency is improved.

[0005] In order to solve the above problems, it is particularly important to develop a liquid cooling device with automatic liquid injection function. Summary of the invention

[0006] The object of the present invention is to provide a liquid cooling device supporting automatic liquid injection.

[0007] In order to solve the above technical problems, the present invention provides a liquid cooling device supporting automatic liquid injection, comprising:

[0008] A cooling unit, wherein the cooling unit is used to cool the device body;

[0009] a first liquid cooling water tank, the first liquid cooling water tank being in communication with the cooling unit and circulating cooling liquid thereto;

[0010] a second liquid cooling water tank, the second liquid cooling water tank being connected to the first liquid cooling water tank, a third connecting pipe being installed between the second liquid cooling water tank and the first liquid cooling water tank, and a water level monitoring unit being installed inside the first liquid cooling water tank and the second liquid cooling water tank;

[0011] an exhaust unit, the exhaust unit comprising a fourth connecting pipe communicating with the first liquid-cooling water tank and the second liquid-cooling water tank and a first exhaust chamber connected to the fourth connecting pipe, wherein the first exhaust chamber is connected to the second exhaust chamber;

[0012] A pressure detection unit is installed inside the first exhaust chamber and the second exhaust chamber;

[0013] When the water level monitoring unit detects that the water level in the first liquid cooling water tank is lower than the first preset threshold, the third connecting pipe is opened, and the liquid in the second liquid cooling water tank enters the first liquid cooling water tank; when the pressure detection unit detects that the gas pressure in the first exhaust chamber is greater than the second preset threshold, the second valve is opened, and the gas in the first exhaust chamber enters the second exhaust chamber; when the water level monitoring unit detects that the first liquid cooling water tank is lower than the third preset threshold or the pressure detection unit detects that the gas pressure in the second exhaust chamber is greater than the fourth preset threshold, the second exhaust chamber is opened to exhaust the gas, and the first liquid cooling water tank and the second liquid cooling water tank are opened for liquid replenishment;

[0014] The first preset threshold is greater than the third preset threshold, and the second preset threshold is greater than the fourth preset threshold.

[0015] Furthermore, the cooling unit includes an equipment body and a first connecting pipe and a second connecting pipe connected to the equipment body, a first water pump is installed on the second connecting pipe, a water cooling row is installed on the first connecting pipe, and the first connecting pipe and the second connecting pipe are respectively connected to the first liquid cooling water tank.

[0016] Furthermore, an exhaust valve is installed on one side of the first exhaust chamber, a flow meter is installed at the inlet of the first exhaust chamber and the third connecting pipe, and a display control unit is connected to the second exhaust chamber. The flow meter is used to detect the gas discharged from the first liquid cooling water tank. When it exceeds the preset value of the flow meter, the flow meter transmits the information to the display control unit.

[0017] Furthermore, the first exhaust chamber is communicated with the second exhaust chamber, and a second valve is installed between the first exhaust chamber and the second exhaust chamber.

[0018] Furthermore, when the water level in the first liquid cooling water tank decreases abnormally and the gas discharged from the first liquid cooling water tank exceeds the preset value of the flow meter at the same time, the display control unit controls the first water pump to close, and the second water pump to turn on to pump the liquid in the first liquid cooling water tank and the connecting pipe into the second liquid cooling water tank, and the display control unit controls the second valve to pass the gas in the second exhaust chamber into the pipeline.

[0019] Furthermore, a plurality of first temperature detectors are installed on the device body, and a flow rate controller is installed between the first water pump and the device. The flow rate controller is used to control the flow rate of the liquid in the second connecting pipe according to the temperature detected by the first temperature detector.

[0020] Furthermore, a second temperature detector is installed on one side of the water cooling radiator, and the second temperature detector is used to detect the liquid cooled from the water cooling radiator. When the temperature does not reach a preset threshold, the flow rate is accelerated by the flow rate controller, and the second water pump is turned on to pass the liquid in the second liquid cooling tank into the first liquid cooling tank.

[0021] Furthermore, the liquid flow rate calculation formula is:

[0022]

[0023] Q is the heat load (W), ρ is the density of the coolant (kg / m 3 ), v is the volume flow rate of the coolant (m 3 / s), C P is the specific heat capacity of the coolant (J / kg·K), and ΔT is the temperature change (K).

[0024] The beneficial effects of the present invention are:

[0025] 1. When the water level monitoring unit detects that the water level in the first liquid cooling water tank is lower than the preset threshold, the second water pump starts automatically and the third valve opens at the same time to pump the liquid in the second liquid cooling water tank into the first liquid cooling water tank, ensuring that the cooling system always maintains a sufficient amount of coolant, avoiding a decrease in cooling efficiency or overheating of the equipment due to insufficient coolant. By automatically replenishing the coolant in a timely manner, the system can maintain a stable operating temperature, extend the service life of the equipment and improve the overall performance.

[0026] 2. When the water level in the first liquid cooling water tank decreases abnormally and the gas discharged from the first liquid cooling water tank exceeds the normal value of the flow meter, the display control unit shuts down the first water pump, starts the second water pump to pump the coolant into the second liquid cooling water tank, and then opens the second valve to allow the gas in the second exhaust chamber to flow smoothly into the pipeline and quickly fill the pipelines to detect and determine the leakage location.

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0040] like Figure 1-4 As shown, a liquid cooling device supporting automatic liquid injection of the present invention includes: a cooling unit 1, the cooling unit 1 includes an equipment body 16 and a first connecting pipe 11 and a second connecting pipe 12 connected to the equipment body 16, a first water pump 13 is installed on the second connecting pipe 12, and a water cooling row 14 is installed on the first connecting pipe 11.

[0041] The first connecting pipe 11 is directly connected to the device body 16, on which a water cooling radiator 14 is installed. The coolant is used to conduct heat from the device body 16, and then the heat is transferred to other parts of the system through liquid circulation to dissipate heat. The second connecting pipe 12 is also connected to the device body 16, and the coolant is pushed to flow in the entire system through the first water pump 13 to ensure that the coolant can continuously absorb and transfer heat.

[0042] A first liquid-cooled water tank 3, the first liquid-cooled water tank 3 is connected to the first connecting pipe 11 and the second connecting pipe 12, a second liquid-cooled water tank 31, a third connecting pipe 32 is installed between the second liquid-cooled water tank 31 and the first liquid-cooled water tank 3, the second liquid-cooled water tank 31 is connected to the first liquid-cooled water tank 3, and a water level monitoring unit 33 is installed inside the first liquid-cooled water tank 3 and the second liquid-cooled water tank 31.

[0043] The first connecting pipe 11 and the second connecting pipe 12 of the first liquid cooling water tank 3 are connected, and the cooling liquid flows from the first liquid cooling water tank 3 to the equipment body 16, absorbs heat at the water cooling row 14, and then flows back to the first liquid cooling water tank 3, forming a closed circulation system.

[0044] The second liquid cooling water tank 31 is connected to the first liquid cooling water tank 3 through the third connecting pipe 32. The first liquid cooling water tank 3 and the second liquid cooling water tank 31 can exchange cooling liquid with each other, which increases the cooling capacity of the system under high load. When the system is running under high load for a long time, the temperature of the cooling liquid in the first liquid cooling water tank 3 may rise. At this time, the cooler cooling liquid in the second liquid cooling water tank 31 can flow into the first liquid cooling water tank 3 through the third connecting pipe 32 to help further reduce the temperature. At the same time, the second liquid cooling water tank 31 is connected to the external water pipe for continuous liquid supply. At the same time, the second liquid cooling water tank 31 can pump water in the first liquid cooling water tank 3 into it. By setting a water level monitoring unit 33 in the two water tanks, it is used to monitor the water level of the cooling liquid in the two water tanks in real time to ensure that there is enough cooling liquid circulating in the system to maintain an effective cooling effect. When the water level is detected to be lower than the preset value, the water in the second liquid cooling water tank 31 can be automatically replenished to the first liquid cooling water tank 3.

[0045] Automatic water injection test data (such as Figure 4 ):

[0046] The reason why the water volume does not reach the preset value after the automatic injection is completed is: because of the program setting, the actual water injection volume = the preset value of water full - (the initial value of water volume - the water volume after the cooling system runs stably) - the water volume when the automatic injection is turned on, to prevent abnormal backflow function;

[0047] Long-term operation leads to water shortage, and the water pump inside the machine drains water out, resulting in water shortage;

[0048] The exhaust unit 4 includes a fourth connecting pipe 41 connected to the first liquid-cooling water tank 3 and the second liquid-cooling water tank 31 and a first exhaust chamber 43 connected to the fourth connecting pipe 41, the first exhaust chamber 43 is connected to the second exhaust chamber 44, and pressure detection units are installed inside the first exhaust chamber 43 and the second exhaust chamber 44;

[0049] The second exhaust chamber 44 is used to detect the air tightness of the liquid cooling device according to the first exhaust chamber 43 and the water level monitoring unit 33 ; the display control unit 5 is connected to the second exhaust chamber 44 .

[0050] The fourth connecting pipe 41 connects the first liquid cooling water tank 3 and the second liquid cooling water tank 31 to the exhaust system. The gases accumulated in the two water tanks can be effectively guided to the exhaust unit 4 for treatment. The two exhaust chambers are installed in sequence on the exhaust path. The first exhaust chamber 43 first collects the gas from the cooling system and discharges it through the exhaust valve 42. The second exhaust chamber 44 stores gas, which can be a colorless non-toxic gas such as helium. When the entire device leaks, the second exhaust chamber 44 can be opened to pass gas into the pipeline through which the coolant flows for detection.

[0051] The display control unit 5 is used to receive the information detected by the water level monitoring unit 33 and the flow meter 45, and control the first water pump 13, the second water pump 34, the exhaust valve 42, the second valve 46 and the flow rate controller 21. By analyzing these data, the display control unit 5 can provide the user with instant system status feedback.

[0052] An exhaust valve 42 is installed on one side of the first exhaust chamber 43, and a flow meter 45 is installed at the inlet of the first exhaust chamber 43 and the third connecting pipe 32. The flow meter 45 is used to detect the gas discharged from the first liquid cooling water tank 3. When it exceeds the preset value of the flow meter 45, the flow meter 45 transmits the information to the display control unit 5.

[0053] When it is detected that there is gas that needs to be discharged, the exhaust valve 42 is opened to discharge the gas from the system to ensure that the flow of coolant is not affected by gas accumulation, thereby maintaining the cooling efficiency, and the amount of gas discharged from the first liquid cooling water tank 3 is detected by the flow meter 45. By monitoring the gas flow, the flow meter 45 can be set to a suitable monitoring interval. When it exceeds the preset value, it is an abnormal state. When it is in an abnormal state, the flow meter 45 transmits information to the display control unit 5 to notify the staff to observe whether there is leakage or other abnormalities.

[0054] A second water pump 34 is installed on the third connecting pipe 32 , and a third valve 35 is installed on one side of the second water pump 34 . When the water level in the first liquid cooling water tank 3 decreases, the second water pump 34 automatically starts to pump the liquid in the second liquid cooling water tank 31 into the first liquid cooling water tank 3 .

[0055] The second water pump 34 is responsible for transmitting coolant between the first liquid-cooling water tank 3 and the second liquid-cooling water tank 31. When the water level monitoring unit 33 detects that the water level in the first liquid-cooling water tank 3 is lower than a preset threshold, the second water pump 34 starts automatically, and the third valve 35 opens at the same time to pump the liquid in the second liquid-cooling water tank 31 into the first liquid-cooling water tank 3, ensuring that the cooling system always maintains a sufficient amount of coolant, avoiding a decrease in cooling efficiency or overheating of the equipment due to insufficient coolant. By automatically replenishing the coolant in a timely manner, the system can maintain a stable operating temperature, extend the service life of the equipment and improve the overall performance.

[0056] The first exhaust chamber 43 is communicated with the second exhaust chamber 44 . A second valve 46 is installed between the first exhaust chamber 43 and the second exhaust chamber 44 . The second valve 46 controls the exhaust of the gas inside the second exhaust chamber 44 .

[0057] When the water level monitoring unit 33 detects that the water level in the first liquid-cooled water tank 3 is lower than the first preset threshold, the third connecting pipe 32 is opened, and the liquid in the second liquid-cooled water tank 31 enters the first liquid-cooled water tank 3; when the pressure detection unit detects that the gas pressure in the first exhaust chamber 43 is greater than the second preset threshold, the second valve 46 is opened, and the gas in the first exhaust chamber 43 enters the second exhaust chamber 44; when the water level monitoring unit 33 detects that the first liquid-cooled water tank 3 is lower than the third preset threshold or the pressure detection unit detects that the gas pressure in the second exhaust chamber 44 is greater than the fourth preset threshold, the second exhaust chamber 44 is opened to exhaust the gas, and the first liquid-cooled water tank 3 and the second liquid-cooled water tank 31 are opened for liquid replenishment;

[0058] The first preset threshold is greater than the third preset threshold, and the second preset threshold is greater than the fourth preset threshold. The first threshold is set to achieve the critical value for the liquid in the second liquid cooling water tank 31 to enter the first liquid cooling water tank 3. At this time, the water level in the liquid cooling water tank can also achieve self-regulation, that is, the liquid in the second liquid cooling water tank 31 enters the first liquid cooling water tank 3; the second threshold is set to achieve the gas in the first exhaust chamber to enter the second exhaust chamber. At this time, the gas in the exhaust chamber can also achieve self-regulation, that is, the gas in the first exhaust chamber enters the second exhaust chamber.

[0059] When the water level monitoring unit detects that the first liquid cooling water tank 3 is lower than the third preset threshold or the pressure detection unit detects that the gas pressure of the second exhaust chamber 44 is greater than the fourth preset threshold, at this time, the water level in the liquid cooling tank or the gas in the exhaust chamber can no longer be self-regulated, and re-liquid filling or gas discharge is required. In addition, the logic takes into account the correlation between the liquid water level and the gas pressure, that is, as long as the water level monitoring unit detects that the first liquid cooling water tank 3 is lower than the third preset threshold or the pressure detection unit detects that the gas pressure of the second exhaust chamber 44 is greater than the fourth preset threshold, re-liquid filling and gas discharge are started.

[0060] The display control unit 5 controls the first water pump 13 to close, and the second water pump 34 to start to pump the liquid in the first liquid-cooled water tank 3 and the connecting pipe into the second liquid-cooled water tank 31. At the same time, the exhaust valve 42 discharges the gas in the first exhaust chamber 43 and closes to ensure that there are no other impurity gases in the system that affect the detection. The display control unit 5 controls the second valve 46 to pass the gas in the second exhaust chamber 44 into the pipeline.

[0061] When the display control unit 5 shows two situations at the same time, it proves that there is a high possibility that there is a leak in the liquid cooling equipment. At this time, the display control unit 5 instructs to shut down the first water pump 13 to prevent further deterioration of coolant loss caused by possible system leakage or other faults. Subsequently, the second water pump 34 is started to pump the liquid in the first liquid cooling water tank 3 and the connecting pipe into the second liquid cooling water tank 31, and reduce the impact of potential leakage by reducing the liquid amount in the first liquid cooling water tank 3. At the same time, the display control unit 5 will also adjust the state of the second valve 46, so that the gas in the second exhaust chamber 44 can smoothly pass into the pipeline, quickly fill each pipeline to detect and determine the leakage location, thereby minimizing the impact on equipment performance. When there is no leakage, the gas is recovered to the second exhaust chamber 44 again.

[0062] A plurality of first temperature detectors 2 are installed on the equipment body 16, and a flow rate controller 21 is installed between the first water pump 13 and the equipment. The flow rate controller 21 is used to control the liquid flow rate in the second connecting pipe 12 according to the temperature detected by the first temperature detector 2, and at the same time, the second water pump is turned on to pass the liquid in the second liquid cooling water tank into the first liquid cooling water tank. The first temperature detector 2 can be a heat flow meter, which is used to directly measure the heat flow through the surface of the equipment body 16, and calculate the liquid flow rate according to the liquid flow rate calculation formula:

[0063]

[0064] Q is the heat load (W), ρ is the density of the coolant (kg / m 3 ), v is the volume flow rate of the coolant (m 3 / s), C P is the specific heat capacity of the coolant (J / kg·K), ΔT is the temperature change (K), and the control flow rate is calculated.

[0065] The multiple first temperature detectors 2 installed on the equipment body 16 are responsible for real-time monitoring of the operating temperature of the equipment. According to the temperature data provided by the first temperature detector 2, the flow rate of the liquid in the second connecting pipe 12 is dynamically adjusted. When the equipment temperature rises, the flow rate controller 21 can increase the flow rate of the coolant to speed up the transfer and dissipation of heat; when the equipment temperature drops to a safe range, the flow rate can be appropriately reduced to save energy and reduce the burden on the cooling system, which not only improves the cooling efficiency, but also avoids over-cooling or insufficient cooling, thereby ensuring that the equipment operates stably within an appropriate temperature range.

[0066] A second temperature detector 15 is installed on one side of the water-cooling radiator 14. The second temperature detector 15 is used to detect the liquid cooled from the water-cooling radiator 14. When the temperature does not reach a preset threshold, the flow rate is accelerated through the flow rate controller 21 to improve the cooling efficiency.

[0067] The second temperature detector 15 is responsible for measuring the temperature of the liquid cooled by the water-cooling row 14. When the liquid temperature measured by the second temperature detector 15 is higher than the preset threshold value, it indicates that the cooling effect has not reached the optimal state. At this time, the flow rate controller 21 will automatically increase the flow rate of the coolant in the second connecting pipe 12 according to this information. Increasing the flow rate helps to improve the efficiency of heat transfer, thereby accelerating the cooling process and ensuring that the temperature of the equipment is effectively controlled, which not only improves the cooling efficiency but also extends the service life of the system.

[0068] Embodiment 2, a method for using a liquid cooling device supporting automatic liquid injection of the present invention, comprising the following steps:

[0069] The cooling process starts: the first water pump 13 is started to pump the coolant from the first liquid cooling water tank 3 into the second connecting pipe 12, and the heat of the equipment body 16 is taken out through the liquid, and the coolant is cooled and returned to the first cooling water tank by the water cooling row 14 on the first connecting pipe 11;

[0070] Automatic water level adjustment: The water level in the first liquid cooling water tank 3 is detected by the water level monitoring unit 33. When the water level in the first liquid cooling water tank 3 decreases normally, the second water pump 34 is automatically started to draw liquid from the second liquid cooling water tank 31 to replenish the first liquid cooling water tank 3. When an abnormality occurs, the information is transmitted to the display control unit 5;

[0071] Temperature monitoring and flow rate adjustment: The temperature of the liquid after cooling of the device and the water-cooling radiator 14 is monitored in real time through the first temperature detector 2 on the device body 16 and the second temperature detector 15 on one side of the water-cooling radiator 14. The flow rate controller 21 automatically adjusts the flow rate of the liquid in the second connecting pipe 12 according to the detected temperature.

[0072] Leakage detection: When the water level in the first liquid cooling water tank 3 decreases abnormally and the gas discharged from the first liquid cooling water tank 3 exceeds the normal value of the flow meter 45, the display control unit 5 executes to close the first water pump 13, and turns on the second water pump 34 to pump the coolant into the second liquid cooling water tank 31. Then, the display control unit 5 opens the second valve 46, so that the gas in the second exhaust chamber 44 can smoothly pass into the pipeline and quickly fill each pipeline to detect and determine the leakage location.

[0073] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
