Description

Technical Field

[0001] The present invention relates to the technical field of servers, and in particular to a production testing device for an immersed server. Background Art

[0002] Liquid cooling technology, as the core key technology for energy saving and efficiency improvement in data centers, has been widely used in the field of server heat dissipation. This technology uses liquid as an efficient heat dissipation medium, mainly including three types: cold plate, immersion and spray. Among them, the application of cold plate liquid cooling technology in the industry has been quite mature; while immersion liquid cooling technology has been widely used in the field of high-performance computing due to its significant energy-saving advantages. Immersion liquid cooling technology is further subdivided into single-phase immersion liquid cooling and two-phase immersion liquid cooling according to whether the coolant undergoes phase change during the circulation heat dissipation process. Since the coolant price of single-phase immersion liquid cooling is relatively low, the deployment cost is lower, the risk is lower, and the maintenance requirements are less, so single-phase immersion liquid cooling has a wider application range and higher maturity; and when the demand is adjusted, the single-phase immersion liquid cooling system is also easier to repair.

[0003] However, in the current production process of single-phase immersion liquid cooling servers, liquid cooling tanks are usually used for testing. This testing method has problems such as large footprint, bulkiness, insufficient space utilization, and low cooling medium utilization. In addition, due to the wide variety of single-phase immersion cooling media and the lack of universal cooling media, whenever there is a demand for different cooling media, the liquid cooling tank, cooling media, and cooling circulation system must be frequently replaced. These frequent replacement operations are not only difficult to construct and costly, but also reduce production efficiency. Summary of the invention

[0004] In view of this, the present invention provides a production test device for an immersion server to solve the problem that when facing the demand for different cooling media, the liquid cooling tank, cooling media and cooling circulation system need to be frequently replaced, the construction is difficult, the cost is high, and the production efficiency is low.

[0005] The present invention provides a production test device for an immersion server, comprising a cold plate heat exchange device, a heat exchange tank and an immersion independent unit; the heat exchange tank is connected to the cold plate heat exchange device; a first cooling medium is arranged in the heat exchange tank, and the first cooling medium circulates between the cold plate heat exchange device and the heat exchange tank; the immersion independent unit comprises a packaging box and a second cooling medium, and the second cooling medium is filled in the packaging box; the packaging box is arranged in the heat exchange tank, and is used to package the immersion server body.

[0006] By setting up a heat exchange tank, the cold plate heat exchange device can cool down the immersed independent unit, realizing the compatibility of the heat exchange system of the immersed server and the cold plate liquid cooling server; by setting up a packaging box, the first cooling medium can be separated from the immersed server body and the second cooling medium, ensuring that the immersed independent unit and the heat exchange tank each operate as an independent circulation system, avoiding the mixing of the first cooling medium and the second cooling medium. When it is necessary to replace a different second cooling medium for testing, there is no need to move or relocate the original heat exchange tank and the cold plate heat exchange device. Only the immersed independent unit needs to be taken out for replacement, avoiding the possibility of repeated construction and excessive construction, reducing the cost of infrastructure construction, improving the flexibility and scalability of the system, reducing operating costs, and maximizing benefits.

[0007] In an optional embodiment, a pump drive unit is further included, and the pump drive unit is connected to the immersion independent unit and is used for circulating the second cooling medium in the packaging box.

[0008] By setting up a pump drive unit, the continuous circulation flow of the second cooling medium inside the packaging box is achieved, ensuring that the second cooling medium can efficiently flow through the immersion server body, effectively absorbing and taking away the heat generated during the operation of the immersion server body, thereby ensuring a good heat dissipation effect of the immersion server body, not only maintaining the immersion server body in an appropriate operating temperature range, but also improving the overall heat dissipation efficiency.

[0009] In an optional embodiment, the pump drive unit includes a liquid supply pipeline, a liquid return pipeline, a driving pump, a flow sensor and a control system; one end of the liquid supply pipeline is connected to the packaging box, and the other end is used to connect to the liquid storage tank of the second cooling medium; and a first valve and a second valve are provided on the liquid supply pipeline, and the first valve and the second valve are arranged at intervals; and the first valve is arranged on the side close to the packaging box; one end of the liquid return pipeline is connected to the packaging box; the other end is arranged between the first valve and the second valve, and is connected to the liquid supply pipeline, and a third valve is arranged on the liquid return pipeline; the driving pump is arranged on the liquid supply pipeline, located between the first valve and the liquid return pipeline; the flow sensor is arranged on the liquid supply pipeline, located between the first valve and the liquid return pipeline; the control system receives flow data from the flow sensor, and when the flow data is lower than a preset value, the control system controls the first valve and the second valve to open, and controls the third valve to close; when the flow data reaches the preset value, the control system controls the first valve and the third valve to open, and controls the second valve to close.

[0010] Since the liquid supply pipeline is equipped with a driving pump, when the first valve and the second valve are in an open state and the third valve is in a closed state, the driving pump can effectively drive the second cooling medium to flow smoothly in the liquid supply pipeline, so that the second cooling medium can enter the packaging box from the liquid supply pipeline; and since the driving pump is arranged between the first valve and the liquid return pipeline, and the first valve is arranged on the side close to the packaging box. When the second valve is closed and the first valve and the third valve are opened at the same time, the driving pump can guide the second cooling medium to form a closed-loop circulation flow system between the packaging box, the liquid supply pipeline and the liquid return pipeline. By setting a flow sensor, the flow of the second cooling medium entering the packaging box can be monitored in real time, and since the control system controls the opening and closing of the first valve, the second valve and the third valve according to the flow data of the flow sensor, the flow of the second cooling medium inside the packaging box is accurately controlled, ensuring that the supply of the second cooling medium is both sufficient and not excessive, and effectively preventing overflow caused by excessive injection.

[0011] In an optional embodiment, the pump drive unit also includes a discharge pipeline, one end of which is arranged between the first valve and the drive pump and connected to the liquid supply pipeline, and the other end is used to connect to the liquid storage tank of the second cooling medium, and a fourth valve is provided on the discharge pipeline.

[0012] By setting up a drainage pipeline, when the immersed independent unit needs to be replaced, the second cooling medium inside the packaging box can be discharged through the drainage pipeline first, which is helpful for replacing the immersed independent unit; and because the drainage pipeline is connected to the storage tank of the second cooling medium, the second cooling medium discharged from the packaging box will not be directly discarded, but will be guided to the storage tank for recovery, thereby realizing the recycling of the second cooling medium, greatly improving the utilization efficiency of resources, and reducing operating costs.

[0013] In an optional embodiment, the pump drive unit further includes a temperature sensor, which is disposed on the liquid return pipeline and is communicatively connected to the control system. The control system controls the frequency of the drive pump according to temperature data from the temperature sensor.

[0014] By setting a temperature sensor, when the temperature sensor accurately monitors that the temperature of the second cooling medium in the return liquid pipeline is at a high level, it means that the temperature of the immersion server body is high. The control system adjusts the working state of the drive pump to speed up the circulation flow rate of the second cooling medium in the system. This dynamic adjustment not only improves the cooling efficiency, but also effectively ensures that the immersion server body is maintained within a suitable operating temperature range, ensuring its stable operation; when the temperature sensor monitors that the temperature of the second cooling medium in the return liquid pipeline is low, it means that the temperature of the immersion server body is low. The control system adjusts the working state of the drive pump to slow down the circulation flow rate of the second cooling medium, thereby achieving effective energy conservation without affecting the server's heat dissipation requirements.

[0015] In an optional embodiment, the pump drive unit further includes a filter, which is disposed on the liquid supply pipeline and located between the first valve and the liquid return pipeline.

[0016] Since the filter is arranged between the first valve and the liquid return line, during the liquid filling process, when the second cooling medium enters the packaging box, the filter can first purify it and effectively remove the particles and impurities that may be carried, thereby ensuring that the second cooling medium entering the packaging box has a high degree of purity from the source, providing a clean and stable operating environment for the immersion server body; during the circulation process, when the second cooling medium flows through the liquid return line and the liquid supply line in sequence and enters the packaging box again, the filter will also purify it again, thereby further improving the purity of the second cooling medium entering the packaging box during the circulation process, thereby ensuring the long-term stable operation of the immersion server body.

[0017] In an optional embodiment, the pump drive unit further includes a pressure sensor, which is disposed on the liquid supply pipeline and located between the packaging box and the liquid discharge pipeline.

[0018] Since the pressure sensor is installed between the packaging box and the discharge pipeline, it can detect the pressure changes of the pipeline during the injection process and the pressure changes of the pipeline during the circulation process. It has comprehensive pressure monitoring capabilities. Once abnormally high pressure is detected, it indicates that there may be a risk of pipeline blockage. The system will immediately issue an alarm and take corresponding preventive measures to avoid damage to the pipeline due to high pressure and the occurrence of abnormal situations such as overload of the drive pump.

[0019] In an optional embodiment, the packaging box includes a liquid inlet assembly, which includes a liquid inlet pipe and multiple nozzles; the liquid inlet pipe is arranged at the bottom of the packaging box, connected to the liquid supply pipeline, and arranged parallel to the bottom surface of the packaging box; the multiple nozzles are arranged in sequence along the length direction of the liquid inlet pipe.

[0020] Since the liquid inlet pipe is arranged at the bottom of the packaging box and is arranged parallel to the bottom surface, and a plurality of nozzles are arranged on the liquid inlet pipe, a water flow beam can be formed when the second cooling medium enters the interior of the packaging box through the nozzle. The water flow beam can promote the flow of the second cooling medium existing inside the packaging box, which not only enhances the uniform mixing and distribution of the second cooling medium, but also promotes the convection effect of the second cooling medium inside the packaging box, so that the second cooling medium can more fully exchange heat with the immersion server body, thereby achieving an efficient heat dissipation effect.

[0021] In an optional embodiment, the packaging box includes a liquid return component, which includes a liquid outlet pipe and multiple liquid outlets; the liquid outlet pipe is arranged inside the packaging box, connected to the liquid return pipeline, and extends along the height direction of the packaging box; the multiple liquid outlets are arranged in sequence along the length direction of the liquid outlet pipe.

[0022] Since the liquid outlet pipe extends along the height direction of the packaging box, the liquid outlet pipe can cover a larger area of ​​the packaging box, and a plurality of liquid outlets are provided on the liquid outlet pipe. When the second cooling medium flows out through the liquid outlets, it will take away the heat of various areas inside the packaging box, and can disturb the second cooling medium in the entire internal area of ​​the packaging box, thereby accelerating the heat dissipation speed; effectively avoiding the problem of local high temperature or local low temperature, and ensuring the uniformity of temperature distribution inside the packaging box.

[0023] In an optional embodiment, a water inlet and a water outlet are provided on the heat exchange tank, and the water inlet and the water outlet are respectively arranged on two opposite side walls of the heat exchange tank, and the water inlet is arranged near the bottom of the heat exchange tank, and the water outlet is arranged near the top of the heat exchange tank.

[0024] Since the water inlet is arranged near the bottom of the heat exchange tank, and the water outlet is arranged near the top of the heat exchange tank, the first cooling medium has an upper in-and-lower-out flow pattern inside the heat exchange tank. When the first cooling medium enters the heat exchange tank from the water inlet, it can start to exchange heat with the immersed independent unit inside the heat exchange tank from the bottom. The first cooling medium continuously absorbs heat during the rising process, and achieves a large-area contact with the packaging box of the immersed independent unit, which not only ensures that the first cooling medium can fully exchange heat with the immersed independent unit, but also promotes the uniform distribution of heat inside the heat exchange tank, and accelerates the overall heat exchange efficiency.

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0032] Combine the following Figures 1 to 3 , describing an embodiment of the present invention.

[0033] According to an embodiment of the present invention, a production test device for an immersion server is provided, comprising a cold plate heat exchange device, a heat exchange tank 2 and an immersion independent unit; the heat exchange tank 2 is connected to the cold plate heat exchange device; a first cooling medium is provided in the heat exchange tank 2, and the first cooling medium circulates between the cold plate heat exchange device and the heat exchange tank 2; the immersion independent unit comprises a packaging box 31 and a second cooling medium 32, and the second cooling medium 32 is filled in the packaging box 31; the packaging box 31 is arranged in the heat exchange tank 2, and is used to package the immersion server body 4.

[0034] By setting up the heat exchange tank 2, the cold plate heat exchange device can cool down the immersed independent unit, thereby achieving compatibility between the heat exchange systems of the immersed server and the cold plate liquid cooling server; by setting up the packaging box 31, the first cooling medium can be separated from the immersed server body 4 and the second cooling medium 32, ensuring that the immersed independent unit and the heat exchange tank 2 each operate as an independent circulation system, avoiding the mixing of the first cooling medium and the second cooling medium 32. When it is necessary to replace a different second cooling medium 32 for testing, there is no need to move or relocate the original heat exchange tank 2 and the cold plate heat exchange device. Only the immersed independent unit needs to be taken out for replacement, avoiding the possibility of repeated construction and excessive construction, reducing the cost of infrastructure construction, improving the flexibility and scalability of the system, reducing operating costs, and maximizing benefits.

[0035] In a specific implementation, the packaging box 31 is in direct contact with the first cooling medium for heat exchange. The box body of the packaging box 31 is made by processes such as indentation, roughening or welding folds to increase the heat exchange area between the box body of the packaging box 31 and the first cooling medium, ensuring that the heat of the immersed independent unit can be transferred out in time.

[0036] In a specific embodiment, the cold plate heat exchange device includes a cold capacity distribution unit 11, a cold source 12, a primary side circulation pipe network 13 and a secondary side circulation pipe network 14; the primary side circulation pipe network 13 is connected to the cold capacity distribution unit 11 and the cold source 12, and the third cooling medium circulates between the cold capacity distribution unit 11 and the cold source 12 through the primary side circulation pipe network 13; the secondary side circulation pipe network 14 is connected to the cold capacity distribution unit 11 and the heat exchange tank 2, and the first cooling medium circulates between the cold capacity distribution unit 11 and the heat exchange tank 2 through the secondary side circulation pipe network 14.

[0037] In a specific embodiment, the cold source 12 is a device that continuously provides cold air for the cold plate heat exchanger and dissipates the heat generated by the cold plate heat exchanger into the atmosphere; the cold source 12 can be an air-cooled chilled water system, a water-cooled chilled water system or a closed cooling tower, etc., or it can be a natural air cooling unit, a mechanical refrigeration unit or a hybrid unit of natural air cooling and mechanical refrigeration.

[0038] In a specific implementation, the third cooling medium can be ethylene glycol or propylene glycol solution. The specific third cooling medium is ethylene glycol solution; since the primary side circulation pipe network 13 is connected to the cold source 12 and may be in an outdoor environment, setting the third cooling medium to ethylene glycol solution has a good antifreeze effect.

[0039] In a specific embodiment, a heat exchanger is provided inside the cooling distribution unit 11, and the heat exchanger may be a plate heat exchanger, a shell and tube heat exchanger, etc. The heat exchanger is used to isolate the third cooling medium and the first cooling medium and exchange energy, and the heat of the first cooling medium is transferred to the third cooling medium to cool the first cooling medium, thereby achieving cooling of the immersed independent unit by the heat exchange tank 2; and the third cooling medium transfers the heat to the cold source 12 for heat dissipation and cooling.

[0040] In a specific implementation, one cold source 12 can be connected to multiple cold distribution units 11 at the same time.

[0041] In a specific implementation, a variable frequency pump is provided inside the cooling distribution unit 11 to provide power for the first cooling medium in the secondary side circulation pipe network 14 to ensure that the first cooling medium can reach the heat exchange tank 2 .

[0042] In a specific implementation, the first cooling medium may be pure water. Compared with solutions such as ethylene glycol and propylene glycol, pure water is more environmentally friendly, has a better cost performance, and is more compatible with the box materials it contacts.

[0043] In a specific embodiment, the first cooling medium flowing in the secondary side circulation pipe network 14 and the heat exchange tank 2 can be the cooling medium of the cold plate liquid cooling server, so the cold plate heat exchange device can be used for cooling the cold plate liquid cooling server and for cooling the immersed independent unit.

[0044] In one embodiment, a pump drive unit 5 is further included, and the pump drive unit 5 is connected to the immersion independent unit and is used for circulating the second cooling medium 32 in the packaging box 31 .

[0045] By setting up the pump drive unit 5, the continuous circulation flow of the second cooling medium 32 inside the packaging box 31 is achieved, ensuring that the second cooling medium 32 can efficiently flow through the immersion server body 4, effectively absorbing and taking away the heat generated during the operation of the immersion server body 4, thereby ensuring a good heat dissipation effect of the immersion server body 4, not only maintaining the immersion server body 4 in an appropriate operating temperature range, but also improving the overall heat dissipation efficiency.

[0046] In one embodiment, the pump drive unit 5 includes a liquid supply pipeline 51, a liquid return pipeline 52, a driving pump 53, a flow sensor 54 and a control system; one end of the liquid supply pipeline 51 is connected to the packaging box 31, and the other end is used to communicate with the liquid storage tank of the second cooling medium 32; and a first valve 511 and a second valve 512 are provided on the liquid supply pipeline 51, and the first valve 511 and the second valve 512 are arranged at intervals; and the first valve 511 is arranged on a side close to the packaging box 31; one end of the liquid return pipeline 52 is connected to the packaging box 31; the other end is arranged between the first valve 511 and the second valve 512, and is connected to the liquid supply pipeline 51, A third valve 521 is provided on the liquid return pipeline 52; the driving pump 53 is arranged on the liquid supply pipeline 51, and is located between the first valve 511 and the liquid return pipeline 52; the flow sensor 54 is arranged on the liquid supply pipeline 51, and is located between the first valve 511 and the liquid return pipeline 52; the control system receives flow data from the flow sensor 54, and when the flow data is lower than a preset value, the control system controls the first valve 511 and the second valve 512 to open, and controls the third valve 521 to close; when the flow data reaches the preset value, the control system controls the first valve 511 and the third valve 521 to open, and controls the second valve 512 to close.

[0047] Since the driving pump 53 is provided on the liquid supply pipeline 51, when the first valve 511 and the second valve 512 are in an open state and the third valve 521 is in a closed state, the driving pump 53 can effectively drive the second cooling medium 32 to flow smoothly in the liquid supply pipeline 51, so that the second cooling medium 32 can enter the packaging box 31 from the liquid supply pipeline 51; and since the driving pump 53 is arranged between the first valve 511 and the liquid return pipeline 52, and the first valve 511 is arranged on a side close to the packaging box 31. When the second valve 512 is closed and the first valve 511 and the third valve 521 are opened, the driving pump 53 can guide the second cooling medium 32 to form a closed-loop circulation flow system between the packaging box 31, the liquid supply pipeline 51 and the liquid return pipeline 52. By setting up the flow sensor 54, the flow of the second cooling medium 32 entering the packaging box 31 can be monitored in real time. Since the control system controls the opening and closing of the first valve 511, the second valve 512 and the third valve 521 according to the flow data of the flow sensor 54, the flow of the second cooling medium 32 inside the packaging box 31 is accurately controlled, ensuring that the supply of the second cooling medium 32 is both sufficient and not excessive, and effectively preventing overflow caused by excessive injection.

[0048] Preferably, the pump drive unit 5 also includes an inlet shock absorber pipe and an outlet shock absorber pipe, the inlet shock absorber pipe is arranged on one side of the liquid inlet of the driving pump 53, and the outlet shock absorber pipe is arranged on one side of the liquid outlet 3122 of the driving pump 53; through the synergistic effect of the inlet shock absorber pipe and the outlet shock absorber pipe, the vibration energy generated by the driving pump 53 during operation is effectively absorbed and eliminated, ensuring a stable connection between the liquid supply pipeline 51 and the return liquid pipeline 52 and the packaging box 31, effectively preventing loose connection due to vibration, avoiding the risk of accidental leakage of the second cooling medium 32 from the connection gap between the liquid supply pipeline 51 and the return liquid pipeline 52 and the packaging box 31, and preventing the second cooling medium from entering the first cooling medium and causing contamination to the first cooling medium.

[0049] In a specific implementation, both ends of the liquid supply pipeline 51 are quick-connect interfaces, and quick connection is achieved with the packaging box 31 and the liquid storage tank of the second cooling medium 32 through the quick-connect interfaces.

[0050] In a specific implementation, the liquid return pipeline 52 is quickly connected to the packaging box 31 through a quick-connect interface.

[0051] In a specific implementation, the first valve 511 , the second valve 512 , and the third valve 521 are all electric ball valves.

[0052] In a specific embodiment, the driving pump 53 is a variable frequency pump.

[0053] In one embodiment, the pump drive unit 5 also includes a drain pipeline 55, one end of which is arranged between the first valve 511 and the drive pump 53 and connected to the liquid supply pipeline 51, and the other end is used to connect to the liquid storage tank of the second cooling medium 32, and a fourth valve 551 is provided on the drain pipeline 55.

[0054] By setting up the drain pipe 55, when the immersed independent unit needs to be replaced, the second cooling medium 32 inside the packaging box 31 can be discharged through the drain pipe 55 first, which is helpful for replacing the immersed independent unit; and because the drain pipe 55 is connected to the liquid storage tank of the second cooling medium 32, the second cooling medium 32 discharged from the packaging box 31 will not be directly discarded, but will be guided to the liquid storage tank for recovery, thereby realizing the recycling of the second cooling medium 32, greatly improving the utilization efficiency of resources, and reducing operating costs.

[0055] In a specific implementation, the liquid discharge pipeline 55 is quickly connected to the liquid storage tank of the second cooling medium 32 through a quick-connect interface.

[0056] In one embodiment, the pump drive unit 5 further includes a temperature sensor 56 , which is disposed on the liquid return pipeline 52 and is in communication with the control system. The control system controls the frequency of the drive pump 53 according to the temperature data of the temperature sensor 56 .

[0057] By setting the temperature sensor 56, when the temperature sensor 56 accurately monitors that the temperature of the second cooling medium 32 in the return liquid pipeline 52 is at a high level, it means that the temperature of the immersion server body 4 is high, and the control system adjusts the working state of the drive pump 53 to speed up the circulation flow rate of the second cooling medium 32 in the system. This dynamic adjustment not only improves the cooling efficiency, but also effectively ensures that the immersion server body 4 is maintained within a suitable operating temperature range and ensures its stable operation; when the temperature sensor 56 monitors that the temperature of the second cooling medium 32 in the return liquid pipeline 52 is low, it means that the temperature of the immersion server body 4 is low, and the control system adjusts the working state of the drive pump 53 to slow down the circulation flow rate of the second cooling medium 32, thereby achieving effective energy conservation without affecting the heat dissipation requirements of the server.

[0058] In one embodiment, the pump drive unit 5 further includes a filter 57 , which is disposed on the liquid supply pipeline 51 and between the first valve 511 and the liquid return pipeline 52 .

[0059] Since the filter 57 is arranged between the first valve 511 and the return liquid pipeline 52, during the injection process, when the second cooling medium 32 enters the packaging box 31, the filter 57 can first purify it and effectively remove the particles and impurities that may be carried, ensuring that the second cooling medium 32 entering the packaging box 31 has a high degree of purity from the source, providing a clean and stable operating environment for the immersion server body 4; during the circulation process, when the second cooling medium 32 flows through the return liquid pipeline 52 and the liquid supply pipeline 51 in turn and enters the packaging box 31 again, the filter 57 will also purify it again, further improving the purity of the second cooling medium 32 entering the packaging box 31 during the circulation process, and ensuring the long-term stable operation of the immersion server body 4.

[0060] In one embodiment, the pump drive unit 5 further includes a pressure sensor 58 , which is disposed on the liquid supply pipeline 51 and located between the packaging box 31 and the liquid discharge pipeline 55 .

[0061] Since the pressure sensor 58 is arranged between the packaging box 31 and the drainage pipeline 55, it can detect the pressure changes of the pipeline during the injection process and the pressure changes of the pipeline during the circulation process. It has comprehensive pressure monitoring capabilities. Once abnormally high pressure is detected, it indicates that there may be a risk of pipeline blockage. The system will immediately issue an alarm and take corresponding preventive measures to avoid damage to the pipeline due to high pressure and the occurrence of abnormal situations such as overloading of the drive pump 53.

[0062] In a specific embodiment, the pressure sensors 58 are arranged in two groups, and the two groups of pressure sensors 58 are arranged at intervals, wherein one group of pressure sensors 58 is arranged on a side close to the discharge pipeline 55 , and the other group of pressure sensors 58 is arranged on a side close to the packaging box 31 .

[0063] In a specific implementation, a manual ball valve 59 is provided between the pressure sensor 58 and the liquid supply pipeline 51 .

[0064] In a specific embodiment, when the second cooling medium 32 is injected into the packaging box 31, the control system opens the first valve 511 and the second valve 512, and controls the third valve 521 to be closed, and the second cooling medium 32 is discharged from the liquid storage tank of the second cooling medium 32 into the liquid supply pipeline 51, and flows through the second valve 512, the driving pump 53, the filter 57, a group of pressure sensors 58, the flow sensor 54, the first valve 511 and another group of pressure sensors 58 in sequence, and then enters the packaging box 31.

[0065] In a specific embodiment, when the second cooling medium 32 circulates, the control system controls the first valve 511 and the third valve 521 to open, and controls the second valve 512 to close; the second cooling medium 32 flows out of the packaging box 31 into the return liquid pipeline 52, flows through the third valve 521, enters the liquid supply pipeline 51, and then flows through the drive pump 53, the filter 57, a group of pressure sensors 58, the flow sensor 54, the first valve 511 and another group of pressure sensors 58 in sequence, and then enters the packaging box 31 again to achieve a circulating flow.

[0066] In a specific embodiment, when the second cooling medium 32 inside the packaging box 31 is discharged, the control system controls the first valve 511 and the second valve 512 to close, and opens the third valve 521 and the fourth valve 551. The second cooling medium 32 flows out of the packaging box 31 into the return liquid pipeline 52, flows through the third valve 521, enters the liquid supply pipeline 51, and then flows through the drive pump 53, the filter 57, enters the discharge pipeline 55, flows through the third valve 521, and finally enters the liquid storage tank of the second cooling medium 32.

[0067] In a specific embodiment, each immersion independent unit is connected to a group of pump-driven units 5, and all operations such as injection, circulation, drainage, heat exchange, etc. of the second cooling medium 32 in the packaging box 31 of the corresponding immersion independent unit can be realized through a group of pump-driven units 5. The overall operation is simple and convenient. Moreover, since the second cooling medium 32 only circulates between the immersion independent unit and the pump-driven unit 5, compared with the traditional immersion liquid cooling system, the usage of the second cooling medium 32 is reduced and the investment cost is lower.

[0068] In one embodiment, the packaging box 31 includes a liquid inlet component 311, which includes a liquid inlet pipe 3111 and a plurality of nozzles 3112; the liquid inlet pipe 3111 is arranged at the bottom of the packaging box 31, connected to the liquid supply pipeline 51, and arranged parallel to the bottom surface of the packaging box 31; the plurality of nozzles 3112 are arranged in sequence along the length direction of the liquid inlet pipe 3111.

[0069] Since the liquid inlet pipe 3111 is arranged at the bottom of the packaging box 31 and is parallel to the bottom surface, and a plurality of nozzles 3112 are provided on the liquid inlet pipe 3111, a water flow beam can be formed when the second cooling medium 32 enters the interior of the packaging box 31 through the nozzle 3112. The water flow beam can promote the flow of the second cooling medium 32 already inside the packaging box 31, which not only enhances the uniform mixing and distribution of the second cooling medium 32, but also promotes the convection effect of the second cooling medium 32 inside the packaging box 31, so that the second cooling medium 32 can more fully exchange heat with the immersion server body 4, thereby achieving an efficient heat dissipation effect.

[0070] In one embodiment, the packaging box 31 includes a liquid return component 312, and the liquid return component 312 includes a liquid outlet pipe 3121 and a plurality of liquid outlets 3122; the liquid outlet pipe 3121 is arranged inside the packaging box 31, connected to the liquid return pipeline 52, and extends along the height direction of the packaging box 31; the plurality of liquid outlets 3122 are arranged in sequence along the length direction of the liquid outlet pipe 3121.

[0071] Since the liquid outlet pipe 3121 extends along the height direction of the packaging box 31, the liquid outlet pipe 3121 can cover a larger area of ​​the packaging box 31, and a plurality of liquid outlets 3122 are provided on the liquid outlet pipe 3121. When the second cooling medium 32 flows out through the liquid outlets 3122, it will take away the heat of each area inside the packaging box 31, and can disturb the second cooling medium 32 in the entire internal area of ​​the packaging box 31, thereby accelerating the heat dissipation speed; effectively avoiding the problem of local high temperature or local low temperature, and ensuring the uniformity of temperature distribution inside the packaging box 31.

[0072] In a specific embodiment, the pump-driven unit 5 and the immersion independent unit are both arranged inside the heat exchange tank 2, and the pump-driven unit 5 is arranged below the immersion independent unit and communicated with the immersion independent unit; one end of the liquid supply pipeline 51 is connected to the liquid inlet pipe 3111, and the other end is extended to the outside of the heat exchange tank 2 and communicated with the liquid storage tank of the second cooling medium 32; one end of the liquid outlet pipe 3121 is connected to the liquid supply pipeline 51, and the other end is extended to the outside of the heat exchange tank 2 and communicated with the liquid storage tank of the second cooling medium 32.

[0073] In one embodiment, a water inlet 21 and a water outlet 22 are provided on the heat exchange tank 2. The water inlet 21 and the water outlet 22 are respectively arranged on two opposite side walls of the heat exchange tank 2, and the water inlet 21 is arranged close to the bottom of the heat exchange tank 2, and the water outlet 22 is arranged close to the top of the heat exchange tank 2.

[0074] Since the water inlet 21 is arranged near the bottom of the heat exchange tank 2, and the water outlet 22 is arranged near the top of the heat exchange tank 2, the first cooling medium has an upper in-and-lower-out flow pattern inside the heat exchange tank 2. When the first cooling medium enters the heat exchange tank 2 from the water inlet 21, it can start to perform heat exchange with the immersed independent unit inside the heat exchange tank 2 from the bottom. The first cooling medium continuously absorbs heat during the rising process, and achieves a large-area contact with the packaging box 31 of the immersed independent unit, which not only ensures that the first cooling medium can perform sufficient heat exchange with the immersed independent unit, but also promotes the uniform distribution of heat inside the heat exchange tank 2, thereby accelerating the overall heat exchange efficiency.

[0075] In a specific implementation, when it is necessary to test the immersion server, the secondary side circulation pipe network 14 of the cold plate heat exchange device is first connected to the heat exchange tank 2, and the first cooling medium circulates between the cold plate heat exchange device and the heat exchange tank 2; then the immersion independent unit is placed in the heat exchange tank 2 and immersed in the first cooling medium; then the control system controls the first valve 511 and the second valve 512 to open, and controls the third valve 521 to close, and the liquid supply pipeline 51 injects the second cooling medium 32 into the packaging box 31; when the flow data monitored by the flow sensor 54 reaches a preset value, the control system controls the first valve 511 and the third valve 521 to open, and controls the second valve 512 to close, and the second cooling medium 32 circulates between the packaging box 31 and the liquid supply pipeline 51 and the liquid return pipeline 52, and the immersion independent unit enters the test mode; after the test is completed, the control system controls the first valve 511 and the second valve 512 to close, and opens the third valve 521 and the fourth valve 551 to achieve the drainage of the packaging box 31. After the test is completed, the immersion independent unit is taken out from the heat exchange tank 2, and the next round of testing can be carried out; and if a different second cooling medium 32 is replaced, only the immersion independent unit and the corresponding pump drive unit 5 need to be replaced. In actual use, the present application can achieve the compatibility of the heat exchange system of the immersion server and the cold plate liquid cooling server, which can save 20% of the cost compared with the immersion server and the cold plate liquid cooling server respectively setting up independent heat exchange systems; when it is necessary to meet the test requirements of different second cooling media 32, only the immersion independent unit and the corresponding pump drive unit 5 need to be replaced, which can save 30% of the cost compared with the traditional method of replacing the entire immersion liquid cooling system.

[0076] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
