Technical Field

[0001] The present invention relates to electronic equipment cooling technology, and in particular to a liquid cooling medium dispersion device and method, and a cooling system. Background Art

[0002] As the power consumption of electronic devices continues to increase, immersion liquid cooling technology has become the core development direction of heat dissipation compared to traditional air cooling and the current mainstream plate-type liquid cooling solutions. Immersion liquid cooling technology refers to immersing heat-generating components in a non-volatile, low-viscosity insulating liquid cooling medium (such as nanofluid medium, mineral oil, fluorinated liquid, etc.), and transferring heat from the heat-generating components inside the electronic device to the external radiator through forced circulation of the liquid cooling medium.

[0003] However, nanofluid media or liquid cooling media such as mineral oil and fluorinated liquid may agglomerate during the circulation process, resulting in a significant attenuation of thermal conductivity and a sudden increase in viscosity, which seriously hinders the practical application of liquid cooling media in the field of immersion liquid cooling.

[0004] Therefore, how to effectively improve the cooling performance of the liquid cooling medium and ensure its use effect in the liquid cooling system is a technical problem that those skilled in the art currently need to solve. Summary of the Invention

[0005] The object of the present invention is to provide a liquid cooling medium dispersion device and method, and a cooling system for reducing energy consumption while ensuring the cooling performance of the liquid cooling medium.

[0006] To achieve the above objectives, the present invention provides the following technical solutions.

[0007] A liquid-cooling medium dispersion device comprises: a dispersion assembly, comprising a dispersion chamber, a dispersion function module, and a filter chamber, the dispersion chamber and the filter chamber being isolated from each other, the dispersion function module being used to disperse the liquid-cooling medium in the dispersion chamber and the filter chamber; a water inlet pipeline, comprising a first branch and a second branch, the first branch being used to supply the liquid-cooling medium in the liquid storage device to flow into an immersion chamber of an electronic device, and the second branch being used to supply the liquid-cooling medium in the liquid storage device to flow into the immersion chamber after passing through the dispersion chamber; a water outlet pipeline being used to supply the liquid-cooling medium in the immersion chamber to flow back to the liquid storage device after passing through the filter chamber; and a controller being used to obtain dispersion state parameter information of the liquid-cooling medium in the filter chamber and adjust the flow ratio between the first branch and the second branch according to the dispersion state parameter information, and / or adjust the power of the dispersion function module; the total flow ratio between the first branch and the second branch being 100%.

[0008] A liquid cooling system includes the above-mentioned liquid cooling medium dispersion device.

[0009] The application discloses a liquid cooling medium dispersion method, which comprises the following steps: acquiring dispersion state parameter information of liquid cooling medium in a filtering cabin; judging a mode of a liquid cooling medium dispersion device according to the dispersion state parameter information, wherein the mode comprises a normal dispersion mode, an enhanced dispersion mode and a self-cleaning mode; when the liquid cooling medium dispersion device is in the enhanced dispersion mode, the flow proportion in a second branch is increased and / or the power of a dispersion function module is increased; when the liquid cooling medium dispersion device is in the self-cleaning mode, the flow proportion in the second branch is kept unchanged and the power of the dispersion function module is increased until the liquid cooling medium dispersion device is in the normal dispersion mode.

[0010] The liquid cooling medium dispersion device has the following beneficial effects: firstly, liquid cooling medium in a liquid storage device is transported into an immersion cabin through a water inlet pipeline, and the liquid cooling medium in the immersion cabin is transported back into the liquid storage device through a water outlet pipeline, so that liquid cooling circulation of the whole liquid cooling medium dispersion device is realized; for the water inlet pipeline, the water inlet pipeline comprises a first branch and a second branch, and a dispersion cabin is connected to the second branch; after the liquid cooling medium in the liquid storage device flows into the water inlet pipeline, the liquid cooling medium flows into the first branch and the second branch respectively; the liquid cooling medium in the first branch directly flows into the immersion cabin, and the liquid cooling medium in the second branch flows into the immersion cabin after passing through the dispersion cabin; the dispersion assembly has two functions, one of which is to disperse and treat the liquid cooling medium in the second branch, and the other of which is to disperse and treat and filter the liquid cooling medium flowing out of the immersion cabin; secondly, a dispersion assembly is arranged between the liquid storage device and the immersion cabin of an electronic device, the dispersion assembly comprises a dispersion cabin, a dispersion function module and a filtering cabin; the dispersion cabin and the filtering cabin are components for liquid cooling medium flow; the dispersion cabin transports the liquid cooling medium in the liquid storage device after dispersion treatment into the immersion cabin, and the filtering cabin transports the liquid cooling medium in the immersion cabin after dispersion and filtration treatment back into the liquid storage device; the dispersion function module in the dispersion assembly can disperse and treat the liquid cooling medium flowing into the immersion cabin and the liquid cooling medium flowing out of the immersion cabin; on one hand, the dispersion function module reduces the particle agglomerates flowing into the immersion cabin, thereby ensuring the cooling efficiency of the liquid cooling medium; on the other hand, the dispersion function module disperses and treats the liquid cooling medium flowing out of the immersion cabin, filters the particle agglomerates and prevents the particle agglomerates from entering the liquid storage device; meanwhile, the dispersion state parameter information of the liquid cooling medium in the filtering cabin can be used to dynamically adjust the flow proportion in the second branch and / or the power of the dispersion function module.

[0011] Further, the liquid cooling medium dispersion device further comprises a controller, which obtains dispersion state parameter information of the liquid cooling medium in the filtering cabin, judges whether the liquid cooling medium in the immersion cabin has agglomeration phenomenon affecting normal cooling function, and selects two operations according to the dispersion state parameter information of the liquid cooling medium in the filtering cabin, the first operation is to increase the flow ratio in the second branch, that is, to make more liquid cooling medium enter the second branch for dispersion treatment, thereby reducing the flow ratio in the first branch and reducing the proportion of the liquid cooling medium directly entering the immersion cabin without dispersion treatment from the source; the second operation is to increase the power of the dispersion function module, that is, to improve the processing capacity of the dispersion function module, so that the liquid cooling medium in the second branch can be dispersed more quickly, thereby reducing the probability of agglomeration of the liquid cooling medium entering the immersion cabin; the above two operations can be operated alternatively, or both operations can be operated simultaneously, and when both operations are operated, the adjustment ratio can be set; of course, one of the operations can be adjusted first, and then the other operation can be adjusted according to the improvement of the dispersion state parameter information of the liquid cooling medium in the filtering cabin, and the actual adjustment process can be selected according to actual needs.

[0012] The liquid cooling medium dispersion device provided by the application divides the liquid cooling medium in the water inlet pipeline into two paths to enter the immersion cabin, so that all the liquid cooling medium does not need to be dispersed, but the flow ratio entering the second branch is selected according to needs, that is, the liquid cooling medium is divided according to the dispersion state parameter information, so that energy waste caused by continuous dispersion treatment of full flow is avoided, energy consumption is saved, and cost is reduced.

[0013] In an embodiment, the dispersion state detection component comprises a first pressure sensor and a second pressure sensor, which are respectively arranged at the inlet side and the outlet side of the filter cabin to obtain the pressure at the inlet side and the outlet side of the filter cabin, and are both connected to the controller, which is configured to calculate the inlet-outlet pressure difference in the filter cabin according to the pressure at the inlet side and the outlet side of the filter cabin, and to adjust the flow ratio in the first branch and the second branch and / or the power of the dispersion function module according to the inlet-outlet pressure difference. With the above arrangement, the first pressure sensor and the second pressure sensor are arranged at the inlet side and the outlet side of the filter cabin respectively, and the inlet-outlet pressure difference of the filter cabin is detected, and according to the basic principle of fluid mechanics, the inlet-outlet pressure difference of the filter cabin increases as the clogging of the filter cabin becomes more serious. By setting a pressure difference threshold and comparing the inlet-outlet pressure difference of the filter cabin with the pressure difference threshold, the flow ratio in the second branch or the power of the dispersion function module can be adjusted and set according to the actual situation, until the inlet-outlet pressure difference of the filter cabin is less than a certain threshold, and the controller determines that the liquid cooling medium in the filter cabin flows smoothly and the particle agglomerates are less. The detection by the first pressure sensor and the second pressure sensor is convenient, low in cost, high in precision and easy to control.

When the liquid cooling medium dispersion device is in the normal dispersion mode, it can be operated according to the initial set parameters at this time. When the liquid cooling medium dispersion device is in the enhanced dispersion mode, the particle agglomerates in the liquid cooling medium increase, and at this time, the flow ratio in the second branch can be increased and / or the power of the dispersion function module can be increased to improve the dispersion degree of the liquid cooling medium in the filter cabin. When the liquid cooling medium dispersion device is in the self-cleaning mode, the flowability of the liquid cooling medium in the immersion cabin is poor at this time, and the power of the dispersion function module needs to be increased until the liquid cooling medium dispersion device returns to the normal dispersion mode to ensure the normal use of the device.

[0028] In order for those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0029] In this embodiment, please refer to Figure 1 The liquid cooling medium dispersion device 1 comprises a dispersion assembly 11, a water inlet pipeline 12, a water outlet pipeline 13, and a controller 14. The dispersion assembly 11 comprises a dispersion cabin 111, a dispersion function module 112, and a filter cabin 113. The dispersion cabin 111 is isolated from the filter cabin 113. The dispersion function module 112 is configured to perform dispersion processing on the liquid cooling medium in the dispersion cabin 111 and the filter cabin 113. The water inlet pipeline 12 comprises a first branch 121 and a second branch 122. The first branch 121 is configured to allow the liquid cooling medium in the liquid storage device 2 to flow into the immersion cabin 3 of the electronic device 4. The second branch 122 is configured to allow the liquid cooling medium in the liquid storage device 2 to flow into the immersion cabin 3 after passing through the dispersion cabin 111. The water outlet pipeline 13 is configured to allow the liquid cooling medium in the immersion cabin 3 to flow back to the liquid storage device 2 after passing through the filter cabin 113. The controller 14 is configured to obtain dispersion state parameter information of the liquid cooling medium in the filter cabin 113, and adjust the flow ratio in the first branch 121 and the second branch 122 and / or the power of the dispersion function module 112 according to the dispersion state parameter information. The sum of the flow ratio in the first branch 121 and the second branch 122 is 100%.

[0030] Specifically, the liquid cooling medium dispersion device 1 can be applied in the electronic device 4, such as an immersion server. The liquid cooling medium can be a nanofluid medium or a mineral oil, a fluorinated liquid, or other medium that may increase in viscosity or may have agglomeration phenomenon during circulation, such as a high-performance graphene fluorinated liquid nanofluid medium. The liquid cooling medium dispersion device 1 is isolated from and independent of the electronic device 4, and is connected only through pipelines. While taking advantage of the excellent heat conduction, temperature uniformity, material compatibility, and other advantages of the liquid cooling medium, the core problem of the high-performance graphene fluorinated liquid and other liquid cooling media that are prone to agglomeration and cause the heat dissipation performance to decay is solved, making it truly feasible to be applied in an immersion liquid cooling server. The heat dissipation performance of a single-phase immersion liquid cooling server system can be further improved to a new height.

[0031] Further, the dispersion state parameter information of the liquid cooling medium is mainly used to represent the dispersion state of the liquid cooling medium, such as viscosity, particle agglomerate concentration, or flow rate of the liquid cooling medium. Parameters that can represent the fluid dispersion state of the liquid cooling medium are all acceptable.

[0032] The liquid cooling medium dispersion device 1 transports the liquid cooling medium in the liquid storage device 2 into the immersion cabin 3 through the water inlet pipeline 12, and transports the liquid cooling medium in the immersion cabin 3 back into the liquid storage device 2 through the water outlet pipeline 13, so as to realize the liquid cooling circulation of the whole liquid cooling medium dispersion device 1; for the water inlet pipeline 12, the water inlet pipeline 12 includes a first branch 121 and a second branch 122, and the dispersion cabin 111 is connected to the second branch 122; after the liquid cooling medium in the liquid storage device 2 flows into the water inlet pipeline 12, it flows into the first branch 121 and the second branch 122 respectively; the liquid cooling medium in the first branch 121 directly flows into the immersion cabin 3, and the liquid cooling medium in the second branch 122 flows into the immersion cabin 3 after passing through the dispersion cabin 111; the dispersion assembly 11 has two functions, one is to disperse the liquid cooling medium in the second branch 122, and the other is to disperse and filter the liquid cooling medium flowing out of the immersion cabin 3; specifically, the dispersion assembly 11 is arranged between the water storage device and the immersion cabin 3 of the electronic equipment 4, the dispersion assembly 11 includes a dispersion cabin 111, a dispersion function module 112 and a filter cabin 113, the dispersion cabin 111 and the filter cabin 113 are components for the flow of the liquid cooling medium, the dispersion cabin 111 transports the liquid cooling medium in the liquid storage device 2 after dispersion treatment to the immersion cabin 3, and the filter cabin 113 transports the liquid cooling medium in the immersion cabin 3 after dispersion and filtration treatment back to the liquid storage device 2; the dispersion function module 112 in the dispersion assembly 11 can disperse the liquid cooling medium flowing into the immersion cabin 3 and the liquid cooling medium flowing out of the immersion cabin 3, on the one hand, to reduce the particle agglomerates flowing into the immersion cabin 3, to ensure the cooling efficiency of the liquid cooling medium, and on the other hand, to disperse the liquid cooling medium flowing out of the immersion cabin 3, and to filter the particle agglomerates to avoid entering the liquid storage device 2; at the same time, the dispersion state parameter information of the liquid cooling medium in the filter cabin can be used to dynamically adjust the flow ratio in the second branch 122 and / or the power of the dispersion function module 112.

[0033] Further, refer to Figure 4The liquid cooling medium dispersion device 1 further comprises a controller 14. The controller 14 acquires the dispersion state parameter information of the liquid cooling medium in the filtering cabin 113, judges whether the liquid cooling medium in the immersion cabin 3 has the agglomeration phenomenon affecting the normal cooling function, and selects two operations according to the dispersion state parameter information of the liquid cooling medium in the filtering cabin 113. The first operation is to increase the flow ratio in the second branch 122, that is, to make more liquid cooling medium enter the second branch 122 for dispersion treatment, thereby reducing the flow ratio in the first branch 121 and reducing the proportion of the liquid cooling medium directly entering the immersion cabin 3 without dispersion treatment from the source. The second operation is to increase the power of the dispersion function module 112, that is, to improve the processing capacity of the dispersion function module 112, so that the liquid cooling medium in the second branch 122 can be dispersed more quickly, thereby reducing the probability of agglomeration of the liquid cooling medium entering the immersion cabin 3. The above two operations can be operated alternatively or simultaneously. When both operations are performed, the adjustment ratio can be set. Of course, one of the operations can be adjusted first, and then the other operation can be adjusted according to the improvement of the dispersion state parameter information of the liquid cooling medium in the filtering cabin 113. The actual adjustment process can be selected according to actual needs.

[0034] The liquid cooling medium dispersion device 1 provided by the application divides the liquid cooling medium in the water inlet pipeline 12 into two paths to enter the immersion cabin 3, without dispersing all the liquid cooling medium. Instead, the flow ratio entering the second branch 122 is selected according to needs, that is, the liquid cooling medium is divided according to the dispersion state parameter information, for example, the nanofluid agglomeration time characteristic dynamic flow division, to avoid energy waste caused by continuous dispersion treatment of full flow, save energy, and reduce cost. While taking advantage of the excellent heat conduction, temperature uniformity, material compatibility and other advantages of the liquid cooling medium, the main defect of easy agglomeration in actual application is avoided.

[0035] In some embodiments, the dispersion function module 112 comprises at least one of a physical dispersion module and a chemical dispersion module. The physical dispersion module disperses the liquid cooling medium by physical means, for example, by jet impact or by stirring with a fan. The chemical dispersion module disperses the liquid cooling medium by chemical means, for example, by adding a dispersant or a stabilizer, such as silicate, polyphosphate, stearate, etc.

[0036] In some embodiments, the physical dispersion module includes an ultrasonic transducer module 1121 and / or a high-pressure microjet module 1122. The ultrasonic transducer module 1121 and the high-pressure microjet module 1122 perform dispersion processing by different means. The ultrasonic transducer module 1121 coarsely disperses the liquid-cooling medium, while the high-pressure microjet module 1122 finely disperses the liquid-cooling medium. The ultrasonic transducer module 1121 and the high-pressure microjet module 1122 are used together for better effect; the chemical dispersion module includes a dispersant injection module 1123 and / or a stabilizer injection module. The dispersant injection module 1123 can select a surfactant, and the stabilizer injection module can be an anionic or cationic stabilizer. The selection of dispersants and stabilizers can be determined according to actual needs and is not limited to the method given in this embodiment. Regarding the use of the dispersant injection module 1123 and the stabilizer injection module, for example, the quantitative addition of dispersants or stabilizers can be achieved through structures such as injection devices.

[0037] In some embodiments, see Figure 2The dispersion module 112 includes at least one of a dual-frequency ultrasonic transducer module, a high-pressure microjet module 1122, and a dispersant injection module 1123. Specifically, between the dispersion chamber 111 and the filtration chamber 113, the dispersion module 112 comprises three independent functional submodules, each of which is independently upgradeable and replaceable. The low-frequency transducer in the dual-frequency ultrasonic transducer module provides a typical 28 kHz ultrasonic wave. Through its transient cavitation fragmentation effect, it generates high-speed microjets and shock waves, directly physically breaking up large micron-sized particle agglomerates. The high-frequency transducer in the dual-frequency ultrasonic transducer module provides a typical 1.2 MHz ultrasonic wave. Through its steady-state cavitation fragmentation effect and acoustic streaming effect, it applies high-frequency shear force to nano-sized particle agglomerates, suppressing secondary agglomeration caused by van der Waals forces and promoting uniform particle distribution. The synergistic combination of low and high frequencies achieves full coverage of particle agglomerate size breakdown from micron to nanometer scale, effectively reducing overall power consumption and temperature rise. The high-pressure microjet module 1122 drives the medium through a micron-sized channel at ultra-high pressure to form a high-speed jet. Utilizing its powerful shear force, collision impact, and turbulent cavitation effect, it further disperses nano-particle agglomerates to a size close to their original size, forming a "coarse crushing + fine grinding" functional combination with the dual-frequency ultrasonic module. The dispersant injection module 1123 is used to inject a dispersant, such as a polyelectrolyte or polymer chain, into the dispersion chamber 111 or the filtration chamber 113. The dispersant can form an adsorption layer on the surface of the nanoparticles. Through the dual effects of steric hindrance and electrostatic repulsion, it offsets the van der Waals and electrostatic forces between the particles, reducing the tendency of spontaneous agglomeration caused by the high surface energy state of the fresh particles after crushing. This achieves a "cluster breaking-cluster stabilization" closed loop based on the physical crushing of ultrasound and microjet, forming a triple synergistic effect with the former two. In actual applications, any one of the dual-frequency ultrasonic transducer module, the high-pressure microjet module 1122, and the dispersant injection module 1123 can be selected, or any two of them can be combined. The best solution is to cooperate with each other.

[0038] In some embodiments, the dispersion component 11 includes a dispersion shell 114, and the dispersion cabin 111, the dispersion functional module 112 and the filtration cabin 113 are all arranged inside the dispersion shell 114, the dispersion cabin 111 and the filtration cabin 113 are respectively located on both sides of the dispersion shell 114, and the dispersion functional module 112 is located between the dispersion cabin 111 and the filtration cabin 113; through the restriction of the dispersion shell 114, the layout of the dispersion cabin 111, the dispersion functional module 112 and the filtration cabin 113 can be facilitated, and the dispersion functional module 112 can be well supported.

[0039] In some embodiments, the decentralized functional module 112 is detachably installed in the decentralized housing 114. Specifically, each submodule in the decentralized functional module 112 is detachably installed in the decentralized housing 114, which is convenient for disassembly, maintenance, or upgrading.

[0040] In some embodiments, referring to Figure 3 Further comprising a flow distribution valve 15, an inlet of the flow distribution valve 15 is communicated with the water inlet pipeline 12, and the flow distribution valve 15 has two outlets communicated with the first branch 121 and the second branch 122 respectively; the flow distribution valve 15 is used to distribute the liquid cooling medium in the liquid storage device 2 to the first branch 121 and the second branch 122 according to a target proportion. Specifically, since the nanofluid has a certain time process of agglomeration and cannot be formed in a short time, and the dispersion of the full-flow liquid cooling medium at all times will cause great power waste and increase in heat generation. Based on energy saving, a flow distribution valve 15 is arranged here to first distribute the full-flow liquid cooling medium from the liquid storage device 2, for example, to adjust only 20% of the flow medium to enter the second branch 122, then flow into the dispersion cabin 111 for processing, and then enter the immersion cabin 3 for heat dissipation after the processing is completed, and the remaining part of the liquid cooling medium directly enters the immersion cabin 3 for heat dissipation along the first branch 121, so that the dispersion of the full-flow medium can be completed before the nanofluid agglomeration, and the power consumption and heat generation of the dispersion device can be reduced to the greatest extent, and the balance of energy efficiency can be realized.

[0042] In some embodiments, the valve body 151 is provided with an input channel 1511, a first valve port 1512, a second valve port 1513, a first output channel 1514, and a second output channel 1515. The first output channel 1514 and the second output channel 1515 are connected to the first branch 121 and the second branch 122, respectively. The first valve port 1512 is located between the input channel 1511 and the first output channel 1514, and the second valve port 1513 is located between the input channel 1511 and the second output channel 1515. The valve core 152 includes a first valve core 1521 and a second valve core 1522. 522, the first valve core 1521 is used to block or release the first valve port 1512, and the second valve core 1522 is used to block or release the second valve port 1513. The first valve core 1521 and the second valve core 1522 are both installed on the transmission rod 153. The transmission rod 153 is used to drive the first valve core 1521 and the second valve core 1522 to move synchronously to reversely adjust the opening of the first valve port 1512 and the second valve port 1513, that is, when the transmission rod 153 moves, it increases the opening of the first valve port 1512 while reducing the opening of the first valve port 1512, and vice versa, which is convenient to control.

The CDU is connected between the cooling tower 21 and the liquid-cooling medium dispersion device 1, and the liquid-cooling medium dispersion device 1 is connected between the CDU and the immersion chamber 3. Specifically, the CDU is connected to the cooling tower 21 through water inlet and outlet pipes. The immersed liquid-cooled electronic equipment 4 will completely immerse the heat-generating components in the liquid-cooling medium. The low-temperature liquid-cooling medium pumped by the CDU drive pump is forced to circulate to complete heat exchange and remove heat.

A detachable and integrated nanofluid liquid cooling medium dispersion device 1 is added between the CDU and the immersion chamber 3, and is connected to the inlet and outlet pipes of the immersion chamber 3 and the inlet and outlet pipes of the CDU through quick-connect connectors.

[0056] In addition to the above-mentioned liquid cooling medium dispersion device 1, please refer to Figure 5 The present invention also provides a liquid cooling medium dispersion method. The liquid cooling medium dispersion method includes the following steps.

[0057] Step S1: obtaining dispersion state parameter information of the liquid cooling medium in the filter cabin 113, and determining the mode of the liquid cooling medium dispersion device 1 according to the dispersion state parameter information. The modes include normal dispersion mode, enhanced dispersion mode and self-cleaning mode.

[0058] Step S2: When the liquid cooling medium dispersion device 1 is in the enhanced dispersion mode, the flow rate ratio in the second branch 122 is increased, and / or the power of the dispersion function module 112 is increased.

[0059] Step S3: When the cooling medium dispersing device 1 is in the self-cleaning mode, the flow ratio in the second branch 122 is kept unchanged, and the power of the dispersing function module 112 is increased until the cooling medium dispersing device 1 is in the normal dispersing mode.

[0060] The liquid cooling medium dispersion method, by acquiring the dispersion state parameter information of the liquid cooling medium in the filtering cabin 113, judges the dispersion state of the liquid cooling medium in the immersion cabin 3 by means of the dispersion state parameter information of the liquid cooling medium in the filtering cabin 113, so as to determine the working mode of the liquid cooling medium dispersion device 1 at this time; when the liquid cooling medium dispersion device 1 is in the normal dispersion mode, it can run according to the initial setting parameters at this time; when the liquid cooling medium dispersion device 1 is in the enhanced dispersion mode, it means that the particle agglomerates in the liquid cooling medium increase, at this time, the flow ratio in the second branch 122 can be increased, and / or the power of the dispersion function module 112 can be increased, to promote the dispersion of the liquid cooling medium in the filtering cabin 113; when the liquid cooling medium dispersion device 1 is in the self-cleaning mode, it means that the flowability of the liquid cooling medium in the immersion cabin 3 is poor at this time, so the power of the dispersion function module 112 needs to be increased until the liquid cooling medium dispersion device 1 returns to the normal dispersion mode, to ensure the normal use of the device.

[0061] In some embodiments, the dispersion state parameter information includes the inlet and outlet pressure difference in the filtering cabin 113; please refer to Figure 6 According to the dispersion state parameter information, the mode of the liquid cooling medium dispersion device 1 includes the following steps.

[0062] Step S11: When the inlet and outlet pressure difference Δp1≤Δp<Δp2, it is judged that the mode of the liquid cooling medium dispersion device 1 is the enhanced dispersion mode, wherein Δp1<Δp2.

[0063] Step S12: When the inlet and outlet pressure difference Δp≥Δp2, it is judged that the mode of the liquid cooling medium dispersion device 1 is the self-cleaning mode.

[0064] Specifically, the inlet side and the outlet side of the filter cabin 113 are respectively provided with a first pressure sensor 161 and a second pressure sensor 162, which are used to detect the pressure difference change in the filter cabin 113; assuming that the pressure detected by the first pressure sensor 161 at the input port of the filter cabin 113 is p1, and the pressure detected by the second pressure sensor 162 at the output port is p2, at this time the pressure difference Δp = p1-p2, according to the basic principle of fluid mechanics, Δp will become larger as the filter cabin 113 is blocked; the dispersion device in the present application is initially provided with two pressure difference thresholds Δp1 and Δp2, and the size relationship between them is Δp1<Δp2, and the specific values can be adjusted and set according to the actual situation. When Δp<Δp1, it is determined that the medium in the filter cabin 113 passes smoothly, and the particle agglomerates are less, and the dispersion device will work in the normal dispersion mode; when Δp becomes larger until Δp1<Δp<Δp2, it is determined that the current dispersion effect of the dispersion device is poor, for example, there are a certain concentration of particle agglomerates in the filter cabin 113, at this time the dispersion device will start the enhanced dispersion mode, including increasing the proportion of the shunt valve 15 to the branch shunt of the dispersion cabin 111, enhancing the working power of the dual-frequency ultrasonic transducer, increasing the driving pressure of the high-pressure micro-jet module 1122, increasing the injection amount / concentration of the dispersant injection module 1123, etc., until Δp decreases to Δp<Δp1, at this time the dispersion device will exit the enhanced dispersion mode and return to the normal dispersion mode; when Δp>Δp2, it is determined that the filter cabin 113 has approached the filtering limit after a long time of filtering material accumulation, at this time the dispersion device will start the self-cleaning mode of the filter cabin 113, and the dual-frequency ultrasonic transducer, the high-pressure micro-jet module 1122 and the dispersant injection module 1123 will act on the filter cabin 113 with a certain intensity, until Δp decreases to Δp<Δp1, at this time the dispersion device will exit the self-cleaning mode of the filter cabin 113 and return to the normal dispersion mode.

[0065] In some embodiments, the method further comprises: step S13: when the outlet-inlet pressure difference Δp<Δp1, it is determined that the mode of the liquid cooling medium dispersion device 1 is the normal dispersion mode; when the liquid cooling medium dispersion device 1 is in the normal dispersion mode, the flow ratio in the second branch 122 and / or the power of the dispersion function module 112 are dynamically adjusted according to the outlet-inlet pressure difference. The above setting is to realize dynamic balance, and in the normal dispersion mode state, the flow ratio in the second branch 122 and / or the power of the dispersion function module 112 are still dynamically adjusted according to the change of the outlet-inlet pressure difference Δp, so as to save energy consumption to the greatest extent.

[0066] Specifically, please refer to Figure 7, the second branch 122 and the power of the dispersion function module 112 are dynamically adjusted according to the inlet and outlet pressure difference, including: step S131, setting a target inlet and outlet pressure difference Δp0; step S132, acquiring the inlet and outlet pressure difference Δp, and when the inlet and outlet pressure difference Δp is greater than Δp0, the flow ratio in the second branch 122 is increased according to a preset ratio amplitude, and after a first preset time is maintained, it is judged whether the inlet and outlet pressure difference Δp is less than or equal to Δp0; if not, the power of the dispersion function module 112 is increased according to a preset power amplitude; the above setting is that when the inlet and outlet pressure difference Δp is greater than Δp0, the flow valve is adjusted first, the flow ratio in the second branch 122 is increased, and if the requirement cannot be met by only changing the flow ratio in the second branch 122, the power of the dispersion function module 112 is increased; because the control of the flow valve is more convenient and the cost is lower, the power balance can be more fully utilized in the normal dispersion mode, and the energy consumption is reduced.

[0067] In some embodiments, further comprising: setting an initial flow ratio of the second branch 122 according to the agglomeration rate constant of the liquid cooling medium, the circulating flow of the liquid storage device 2, the target dispersion state parameter information and the processing efficiency of the liquid cooling medium dispersion device 1. Specifically, in the specific implementation, the full flow medium distributed by the CDU is split by the flow valve 15, for example, the medium flow ratio in the second branch 122 is only adjusted to 20% according to the actual situation, and after the dispersion processing is completed, the remaining part of the medium flow enters the server immersion tank 3 for heat dissipation along the first branch 121; the greater the agglomeration rate constant of the liquid cooling medium, the greater the circulating flow of the liquid storage device 2, the smaller the target dispersion state parameter information, and the higher the processing efficiency of the liquid cooling medium dispersion device 1, the higher the initial flow ratio of the second branch 122.

[0068] The liquid cooling medium dispersion method provided by the application can automatically adjust the working mode and intensity in real time according to the actual situation through the above feedback closed-loop control mechanism, realize the maximum balance of energy efficiency while ensuring the dispersion effect, reduce the working heat generation, and also realize self-cleaning of the device and prolong the working life; by embedding the detachable integrated dispersion device between the CDU and the immersion tank 3, the three-field synergistic dispersion of sound field, flow field and chemical field is realized, and the liquid cooling medium agglomeration problem is efficiently solved; for the energy efficiency balance points, the flow of the dispersion processing is dynamically adjusted by the flow valve 15, and the dispersion intensity is controlled by the pressure sensor feedback, which greatly reduces the power consumption and eliminates over-processing and under-processing; for the industrial scene maintenance difficulties, the whole detachable integrated design is adopted, the internal function submodules are independently selected and designed, and the self-cleaning can be controlled by the pressure sensor feedback, so that the efficient maintenance of the dispersion device is realized.
