[0077] Through the above-mentioned accompanying drawings, specific embodiments of the present application have been shown, and more detailed descriptions will be provided hereinafter. These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0078] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0079] Inside the server, there are a large number of electronic components such as CPUs, memories, hard disks, etc. These components generate heat during operation. The server needs to run continuously for 24 hours, and has extremely high requirements for stability. Excessive temperature will cause the performance of electronic components to decline, and even cause the server to crash and restart frequently, affecting the continuity of business. Therefore, it is crucial for the server to dissipate heat.

[0080] At present, the main server heat dissipation methods are air-cooled heat dissipation and liquid-cooled heat dissipation. As there are more and more heat-generating devices and higher and higher heat generation power inside the server, it is difficult for air-cooled heat dissipation to meet the heat dissipation requirements. Therefore, the application of liquid-cooled heat dissipation is becoming more and more common. Among them, liquid-cooled heat dissipation mainly includes cold plate liquid cooling and immersion liquid cooling. Cold plate liquid cooling requires connecting the cold plates corresponding to different heat-generating devices together through pipelines. However, when there are more heat-generating devices, the pipeline connection will be more complex, and there are more possible leakage points. At the same time, since it is impossible to completely use liquid-cooled methods for all devices inside the cold plate, devices other than the cold plate still need fans for heat dissipation, that is, a hybrid air-liquid heat dissipation method is adopted; immersion liquid cooling is a heat exchange method in which the devices to be cooled are completely immersed in the coolant, which can achieve 100% full liquid cooling and does not require pipelines and cold plates to connect different devices together. Therefore, the complexity of the internal structure of the server can be greatly reduced, and at the same time, the power usage effectiveness (PUE) of the data center can be greatly reduced.

[0081] However, in existing immersion liquid cooling systems, generally, the flow rate of the coolant is adjusted by a circulation pump to adapt to the heat generation power of the heat-generating devices of the devices to be cooled. When the heat generation power of the heat-generating devices increases, it is necessary to significantly increase the output power of the circulation pump to meet the flow rate requirements of the coolant for the heat-generating devices, resulting in a significant increase in the energy consumption of the immersion liquid cooling system.

[0082] In view of the above technical problems, the present application proposes an immersion liquid cooling box and system, which adapt to different heating powers of heating devices by distributing the flow rate of the coolant flowing through the heating devices and other devices outside the heating devices, effectively reducing the energy consumption of the immersion liquid cooling system while achieving rapid heat dissipation of the heating devices.

[0083] The technical solutions of the immersion liquid cooling box and system provided by the present application will be described in detail below through specific embodiments. It should be noted that the following embodiments can exist independently or be combined with each other, and the same or similar content may not be repeated in different embodiments.

[0084] Figure 1 The structural schematic diagram of an immersion liquid cooling box provided by an embodiment of the present application is shown in Figure 1 , in some embodiments, the immersion liquid cooling box includes a first flow equalizing plate 200, a flow equalizing adjustment assembly 300, and a box body 100; the first flow equalizing plate 200 is disposed inside the box body 100, and the first flow equalizing plate 200 divides the internal cavity of the box body 100 into an upper cooling chamber 105 and a drainage chamber 104, and a plurality of first flow equalizing ports 202 and drainage ports 201 for the coolant to flow through are provided on the first flow equalizing plate 200; the drainage port 201 is connected to the heating device of the device 400 to be cooled immersed in the cooling chamber 105 through a drainage pipe 106 to perform targeted heat dissipation on the heating device; the flow equalizing adjustment assembly 300 is disposed inside the box body 100, and the flow equalizing adjustment assembly 300 is used to adjust the opening size of the first flow equalizing port 202; a liquid inlet 103 and an overflow port 102 are provided on the box body 100, the liquid inlet 103 is communicated with the drainage chamber 104, and the overflow port 102 is communicated with the cooling chamber 105.

[0085] In this embodiment, the box body 100 is separated into a cooling chamber 105 and a diversion chamber 104 by a first flow equalizing plate 200. The cooling chamber 105 is used to immerse the device 400 to be cooled, and the diversion chamber 104 is used to guide the coolant into the cooling chamber 105. The high-power heating devices inside the device 400 to be cooled are connected to the diversion port 201 through a diversion pipe 106, so as to realize the targeted diversion of the coolant directly to the area of the high-power heating devices. Other devices inside the device 400 to be cooled are cooled by the cooling liquid flowing through the flow equalizing port. The flow rate of the flow equalizing port and the flow rate of the diversion port 201 are adjusted by the flow equalizing adjustment component 300, so as to adjust the distribution of the internal flow rate of the box body 100, and distribute the flow rate of the coolant flowing through the heating device and other devices outside the heating device, so as to adapt to the different heating powers of the heating devices. And when the heating power of the heating device of the device 400 to be cooled increases, it is not necessary to greatly increase the output power of the circulation pump 600 in the immersion liquid cooling system, and the distribution of the internal flow rate of the box body 100 can be quickly adjusted, so as to quickly increase the cooling flow rate required by the heating device, and take into account the smoothness of the flow rate adjustment, so as to quickly reduce the temperature of the heating device to be cooled. While realizing the rapid heat dissipation of the heating device, the energy consumption of the immersion liquid cooling system is effectively reduced.

[0086] Specifically, for the connection between the diversion pipe 106 and the heating device, a cold plate can be set at the heating part of the heating device, and then the diversion pipe 106 is connected to the cold plate to dissipate heat from the heating device through the cold plate. Using the diversion pipe 106 to guide the coolant to dissipate heat from the heating device in a targeted manner is because compared with the cold plate liquid cooling, the cooling effect of the immersion liquid cooling is worse. Therefore, targeted heat dissipation of the heating device can further improve the heat dissipation efficiency of the heating device.

[0087] Refer to Figure 3 、 Figure 4 and Figure 5 Specifically, the opening size of the first flow equalizing port 202 is adjusted by the flow equalizing adjustment component 300, so as to change the flow cross-sectional area of the first flow equalizing port 202, and adjust the flow rate of the coolant in the area of the first flow equalizing port 202 and the area of the diversion port 201.

[0088] Among them, when the first flow equalizing port 202 is fully opened, the coolant flow rate in the area of the first flow equalizing port 202 is the largest, and the coolant flow rate in the area of the diversion port 201 will be the smallest. At this time, it is applicable to the working condition when the heating power of the heating device is small; when the first flow equalizing port 202 is completely closed, the flow rate in the area of the first flow equalizing port 202 is the smallest, and the coolant flow rate in the area of the diversion port 201 will be the smallest. At this time, it is applicable to the working condition when the heating power of the heating device is extremely large. However, this situation generally does not exist in actual applications, only for extreme illustration; when the first flow equalizing port 202 is partially opened, both the area of the first flow equalizing port 202 and the area of the diversion port 201 have a certain coolant flow rate. At this time, it is applicable to most working conditions of the device 400 to be cooled.

[0089] Specifically, the numbers of the first flow equalizing ports 202 and the drainage ports 201 can be adjusted according to the cooling requirements.

[0090] Specifically, the coolant is mainly divided into two categories: mineral oil-based coolants and fluorinated liquid-based coolants. Among them, the mineral oil-based coolants include natural mineral oils, synthetic oils, etc., and the fluorinated liquid-based coolants include hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), hydrofluoroethers (HFEs), etc.

[0091] Specifically, the first flow equalizing port 202 can be circular, square or oval. When a higher requirement for smoothness of flow rate adjustment is needed, a flow equalizing port with a longer flow cross-section can be used for flow rate adjustment.

[0092] Refer to Figure 1 , optionally, a heat dissipation guide cover 401 is sleeved outside the heat generating device, and the drainage port 201 is communicated with the heat dissipation guide cover 401 through a drainage pipe 106.

[0093] Among them, the heat dissipation guide cover 401 covers the outside of the heat generating device. After the coolant flowing through the drainage port 201 enters the heat dissipation guide cover 401, the heat dissipation guide cover 401 optimizes the liquid flow path to guide the coolant to more evenly perform targeted heat dissipation on the whole body of the heat generating device, so as to increase the heat dissipation area and improve the heat dissipation efficiency.

[0094] Refer to Figure 1 , optionally, a partition plate 107 is further provided on the first flow equalizing plate 200; the height of the partition plate 107 is lower than the top end of the box body 100, and the partition plate 107 and the side wall of the box body 100 enclose an overflow channel 101, and the overflow channel 101 is communicated with the overflow port 102.

[0095] Among them, the overflow channel 101 is formed by enclosing the partition plate 107 and the side wall of the box body 100, and the coolant in the box body 100 is circulated and discharged through the overflow channel 101. The overflow channel 101 usually has a larger cross-sectional area and a smoother drainage path, and can discharge the excess coolant more quickly and smoothly.

[0096] Refer to Figure 2 , in some embodiments, the flow equalizing adjustment assembly 300 includes a second flow equalizing plate 304 stacked with the first flow equalizing plate 200, and a translation mechanism disposed inside the box body 100; a plurality of second flow equalizing ports 305 are provided on the second flow equalizing plate 304; the translation mechanism is used to drive the second flow equalizing plate 304 to move horizontally to adjust the overlapping ratio between the second flow equalizing ports 305 and the first flow equalizing ports 202.

[0097] In this embodiment, refer to Figure 3 , Figure 4 and Figure 5The second flow balancing plate 304 is driven to move horizontally by the translation mechanism, so that the second flow balancing port 305 on the second flow balancing plate 304 is close to overlap or away from the corresponding first flow balancing port 202. When the second flow balancing port 305 is close to the first flow balancing port 202, the second flow balancing port 305 gradually overlaps with the first flow balancing port 202. The larger the overlap area between the second flow balancing port 305 and the first flow balancing port 202, the larger the opening size of the first flow balancing port 202 for the coolant to flow.

[0098] On the contrary, when the second flow equalizing port 305 is away from the first flow equalizing port 202, the second flow equalizing port 305 and the first flow equalizing port 202 are offset away from each other, and the smaller the overlapping area between the second flow equalizing port 305 and the first flow equalizing port 202, the smaller the opening size of the first flow equalizing port 202 for the coolant to flow through.

[0099] Therefore, by controlling the translational movement of the second flow balancing plate 304 using the translation mechanism, the flow rate of the coolant at the first flow balancing port 202 can be adjusted by adjusting the overlap ratio between the second flow balancing port 305 and the first flow balancing port 202 .

[0100] See also Figure 2 Optionally, the translation mechanism includes a gear bar 303, a transmission gear 302 and a first driving mechanism 301; the gear bar 303 is arranged on the second current equalizing plate 304; the first driving mechanism 301 is drivingly connected to the transmission gear 302, and the transmission gear 302 is meshingly connected to the gear bar 303.

[0101] The first driving mechanism 301 is used to drive the transmission gear 302 to rotate, and the transmission gear 302 drives the gear bar 303 to move in translation, so that the gear bar 303 drives the second current equalizing plate 304 to move in translation.

[0102] Specifically, the first driving structure is a reduction motor, which can change the speed and torque of the power machine by adjusting the ratio of the reducer, converting high-power, high-speed original power into low-speed, low-power mechanical energy, thereby meeting the speed requirement of the second current equalizing plate 304.

[0103] See also Figure 6 Optionally, the first flow balancing port 202 and the second flow balancing port 305 are waist-shaped holes.

[0104] Among them, the waist-shaped hole is a strip hole, which can facilitate smoother adjustment of the overlap size of the second flow equalizing port 305 and the first flow equalizing port 202. Compared with the round hole, it can better achieve smooth distribution of the flow rate of the flow equalizing channel and the flow rate of the drainage channel.

[0105] See also Figure 7In some embodiments, the flow equalizing regulating component 300 includes a third flow equalizing plate 308 stacked with the first flow equalizing plate 200, and a rotating mechanism disposed in the box 100; a plurality of third flow equalizing ports 309 are disposed on the third flow equalizing plate 308; the rotating mechanism is used to drive the third flow equalizing plate 308 to rotate horizontally to adjust the overlap ratio between the third flow equalizing port 309 and the first flow equalizing port 202.

[0106] In this embodiment, see Figure 8 , Figure 9 and Figure 10 ,, the third equalizing plate 308 is driven to rotate horizontally by the rotating mechanism, so that the third equalizing port 309 on the third equalizing plate 308 is close to overlap or away from the corresponding first equalizing port 202. When the third equalizing port 309 is close to the first equalizing port 202, the third equalizing port 309 gradually overlaps with the first equalizing port 202, and the larger the overlap area between the third equalizing port 309 and the first equalizing port 202, the larger the opening size of the first equalizing port 202 for the coolant to flow.

[0107] On the contrary, when the third flow equalizing port 309 is away from the first flow equalizing port 202, the third flow equalizing port 309 and the first flow equalizing port 202 are offset away from each other, and the smaller the overlapping area between the third flow equalizing port 309 and the first flow equalizing port 202, the smaller the opening size of the first flow equalizing port 202 for the coolant to flow through.

[0108] Therefore, by using the rotating mechanism to control the horizontal rotation of the second flow balancing plate 304 , the flow rate of the coolant at the first flow balancing port 202 can be adjusted by adjusting the overlap ratio between the third flow balancing port 309 and the first flow balancing port 202 .

[0109] See also Figure 7 Optionally, the rotating mechanism includes a rotating shaft 307 and a second driving mechanism 306 ; the second driving mechanism 306 is drivingly connected to the rotating shaft 307 , and the rotating shaft 307 is connected to the third current equalizing plate 308 .

[0110] The second driving mechanism 306 drives the rotating shaft 307 to rotate, and the rotating shaft 307 drives the third current equalizing plate 308 to rotate horizontally.

[0111] Specifically, the second driving mechanism 306 can be a reduction motor, which can change the speed and torque of the power machine by adjusting the ratio of the reducer, converting high-power, high-speed original power into low-speed, low-power mechanical energy, thereby meeting the speed requirement of the third current equalizing plate 308.

[0112] See also Figure 11, in some embodiments, the flow equalizing adjustment component 300 includes a fourth flow equalizing plate 311 arranged in parallel with the first flow equalizing plate 200, and a lifting mechanism disposed within the box body 100; a plurality of conical bosses 312 are provided on the fourth flow equalizing plate 311; the lifting mechanism is configured to drive the fourth flow equalizing plate 311 to move up and down, so as to adjust the length of the conical bosses 312 extending into the first flow equalizing port 202.

[0113] In this embodiment, referring to Figure 12 , Figure 13 and Figure 14 , by driving the fourth flow equalizing plate 311 to move up and down through the lifting mechanism, the fourth flow equalizing plate 311 is brought closer to or farther away from the first flow equalizing plate 200. When the fourth flow equalizing plate 311 approaches the first flow equalizing plate 200, the conical bosses 312 extend into the first flow equalizing port 202. Due to the conical structure of the conical bosses 312, when they extend into the first flow equalizing port 202, the length of the conical bosses 312 extending into the first flow equalizing port 202 becomes larger and larger, and the size of the opening of the first flow equalizing port 202 through which the coolant can flow becomes smaller and smaller.

[0114] Conversely, when the fourth flow equalizing plate 311 moves away from the first flow equalizing plate 200, the conical bosses 312 withdraw from the first flow equalizing port 202. Due to the conical structure of the conical bosses 312, when they withdraw from the first flow equalizing port 202, the length of the conical bosses 312 extending into the first flow equalizing port 202 becomes smaller and smaller, and the size of the opening of the first flow equalizing port 202 through which the coolant can flow becomes larger and larger.

[0115] Therefore, by using the lifting to control the up and down movement of the fourth flow equalizing plate 311, the flow rate of the coolant at the first flow equalizing port 202 can be adjusted by adjusting the length of the conical bosses 312 extending into the first flow equalizing port 202.

[0116] Specifically, the lifting mechanism is a linear driving mechanism such as a hydraulic cylinder or a pneumatic cylinder, and the lifting mechanism is vertically arranged to achieve the lifting drive of the fourth flow equalizing plate 311.

[0117] Figure 15 is a schematic structural diagram of an immersion liquid cooling system provided by an embodiment of the present application. Referring to Figure 15 , the immersion liquid cooling system includes a circulation pump 600, a heat exchanger 500, and the above-mentioned immersion liquid cooling box; the liquid inlet end of the heat exchanger 500 is communicated with the overflow port 102 of the immersion liquid cooling box, the liquid outlet end of the heat exchanger 500 is communicated with the liquid inlet end of the circulation pump 600, and the liquid outlet end of the circulation pump 600 is communicated with the liquid inlet port 103 of the immersion liquid cooling box.

[0118] In this embodiment, the immersion liquid cooling box is used to hold the coolant and the electronic devices to be cooled (such as servers, chips, etc.). By completely immersing the device 400 to be cooled in the coolant, it is ensured that heat can be directly and efficiently transferred to the coolant. The circulation pump 600 is the power source in the immersion liquid cooling system and is responsible for driving the coolant to circulate in the system. It generates pressure to form a closed-loop flow of the coolant between the immersion liquid cooling box and the heat exchanger 500, thereby continuously removing the heat generated by the device 400 to be cooled. The heat exchanger 500 is used to dissipate the heat in the coolant to the external environment. The heat exchanger 500 cools the coolant by exchanging heat between the coolant and the external environment (such as air or a cooling medium), thereby maintaining its cooling capacity.

[0119] Therefore, in the immersion cooling system, the device 400 to be cooled is completely immersed in the coolant in the immersion liquid cooling box, and heat is directly transferred from the heat-generating device to the coolant, causing the temperature of the coolant to rise. The circulation pump 600 is started to generate pressure to make the coolant circulate between the immersion liquid cooling box and the heat exchanger 500. The heated coolant is transported to the heat exchanger 500. In the heat exchanger 500, the coolant exchanges heat with the external environment, and the heat is dissipated to the external environment, and the temperature of the coolant decreases. The cooled coolant is transported back to the immersion liquid cooling box by the circulation pump 600 again to continue absorbing the heat of the device 400 to be cooled, forming a continuous heat dissipation cycle.

[0120] Specifically for the device to be cooled, in the immersion cooling system, multiple temperature sensors, pressure sensors, and flow sensors are also provided to more precisely control the flow rate of the coolant, the working power of the circulation pump 600, the heat dissipation efficiency of the device 400 to be cooled, etc.
