These drawings and text descriptions are not intended to limit the scope 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 DESCRIPTION

[0069] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0070] As described in the background technology, the immersion liquid cooling system in the related technology has the defect of low cooling efficiency. The inventors have found that the main reason for this problem is that the immersion liquid cooling system usually includes a liquid cooling device and a heat exchange device. The liquid cooling device has a first refrigerant and an object to be cooled immersed in the first refrigerant. The object to be cooled absorbs the heat of the first refrigerant and is cooled. After that, the first refrigerant that absorbs the heat of the object to be cooled will flow into the heat exchanger and exchange heat with the air and cool down. The cooled first refrigerant flows back to the liquid cooling device to continue cooling the object to be cooled. However, the first refrigerant flowing through the heat exchange device mainly relies on heat exchange with the air, and it is difficult to restore to an ideal state, thereby reducing the cooling effect of the immersion liquid cooling system.

[0071] The immersion liquid cooling system provided in the embodiment of the present application is provided with a cooling device on the top of the heat exchange equipment. When the first refrigerant after absorbing the object to be cooled enters the heat exchanger, the first refrigerant can exchange heat with the air, and can also exchange heat with the second refrigerant flowing out from the refrigerant outlet of the cooling device and flowing to the heat exchanger. In this way, the heat exchange effect of the heat exchanger can be enhanced, thereby better reducing the temperature of the first refrigerant passing through the heat exchanger, thereby improving the cooling effect of the immersion liquid cooling system.

[0072] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0073] The immersion liquid cooling system provided in the embodiment of the present application is used to cool the object to be cooled 120 to reduce the temperature of the object to be cooled 120, wherein the object to be cooled 120 can be equipment in a data center, such as a liquid-cooled server, a PDU power supply supporting the liquid-cooled server, a weak-current integrated wiring system supporting the liquid-cooled server, etc.

[0074] Please refer to Figures 1 to 4The immersion liquid cooling system includes a liquid cooling device 100 and a heat exchange device 200, wherein the liquid cooling device 100 includes a liquid cooling box 110, and the liquid cooling box 110 is used to accommodate a first refrigerant and an object to be cooled 120, wherein the first refrigerant is used to cool the object to be cooled 120, and the first refrigerant has a strong cooling capacity. For example, the first refrigerant may include mineral oil, synthetic oil, fluorocarbon compounds, etc.

[0075] In one example, a bearing member (not shown in the figure) detachably connected to the liquid cooling box 110 is provided in the liquid cooling box 110, and a storage space is provided in the bearing member. For example, the bearing member may include a first support plate and a second support plate and a third support plate spaced apart on the first support plate. The first support plate, the second support plate and the third support plate form a storage space with a top opening, and the top opening can facilitate the placement or removal of the object to be cooled 120. In this example, the second support plate and the first support plate are arranged at an angle to each other, and the third support plate and the first support plate are arranged at an angle to each other, so that the storage space is a structure with a large top and a small bottom. In this way, on the one hand, it is more convenient to place or remove the object to be cooled 120 from the storage space; on the other hand, it can facilitate the installation of other equipment. For example, the surface of the second support plate facing the storage space can be used to set the power distribution unit (PDU) 130, and the surface of the third support plate facing the storage space is used to set the integrated wiring weak current cable 140.

[0076] The object to be cooled 120 is detachably connected in the accommodating space. For example, the first support plate is provided with an accommodating groove, and one end of the object to be cooled 120 can be inserted into the accommodating groove, so that the object to be cooled 120 can be conveniently placed in or removed from the accommodating space. It should be noted that the accommodating space can accommodate one object to be cooled 120, or multiple objects to be cooled 120. For example, the first support plate has multiple accommodating grooves arranged at intervals, and each accommodating groove is used to fix one object to be cooled 120. In this way, the scope of application of the immersion liquid cooling system can be improved.

[0077] The heat exchange equipment 200 includes a heat exchanger 210 and a cooling device 220, wherein the cooling device 220 has a second refrigerant, wherein the second refrigerant may be the same as or different from the first refrigerant. For example, the second refrigerant may be water with lower volatility. In this way, the consumption of the second refrigerant may be reduced, thereby reducing the cost of the immersion liquid cooling system.

[0078] The heat exchanger 210 is connected to the liquid cooling box 110, and the cooling device 220 has a refrigerant outlet (not shown in the figure). The first refrigerant entering the heat exchanger 210 is configured to exchange heat with the air and the second refrigerant flowing out of the refrigerant outlet of the cooling device 220 and flowing to the heat exchanger 210. In this way, when the first refrigerant after absorbing the object to be cooled 120 enters the heat exchanger 210, the first refrigerant can exchange heat with the air and the second refrigerant flowing out of the refrigerant outlet of the cooling device 220 and flowing to the heat exchanger 210. In this way, the heat exchange effect of the heat exchanger 210 can be enhanced, thereby better reducing the temperature of the first refrigerant passing through the heat exchanger 210, and improving the cooling effect of the immersion liquid cooling system.

[0079] It should be noted that, in the present embodiment, the second refrigerant flowing to the heat exchanger 210 can be understood as the second refrigerant flowing to the surface of the heat exchanger 210, and can also be understood as the heat exchanger 210 having a pipe for circulating the second refrigerant, and the second refrigerant can flow into the heat exchanger 210 from the inlet of the pipe, and then flow out of the heat exchanger 210 from the outlet of the pipe. When the second refrigerant flows in the heat exchanger 210, the first refrigerant entering the heat exchanger 210 can be cooled.

[0080] There are many options for the relative position of the cooling device 220 and the heat exchanger 210. For example, Figure 3 , the cooling device 220 can be located above the heat exchanger 210, and the second refrigerant in the cooling device 220 can be sprayed onto the surface of the heat exchanger 210 by gravity. For another example, the cooling device 220 can be located below the heat exchanger 210, in which case a power pump needs to be provided at the refrigerant outlet of the cooling device 220, and the second refrigerant is transported to the heat exchanger 210 by the power pump.

[0081] In a possible implementation, the heat exchange device 200 further includes a water collector 250, which is disposed below the heat exchanger 210 and is used to collect the second refrigerant after heat exchange with the heat exchanger 210. When the second refrigerant in the cooling device 220 flows to the surface of the heat exchanger 210 through the refrigerant outlet (not shown in the figure), the second refrigerant will flow downward along the surface of the heat exchanger 210 under the influence of gravity. Therefore, in this embodiment, the water collector 250 is disposed below the heat exchanger 210, so that the second refrigerant after heat exchange with the heat exchanger 210 can be collected and reused.

[0082] The collected second refrigerant can be directly transported to the outside of the immersion liquid cooling system by using the water collector 250. A drain port 251 can be provided on the water collector 250. The drain port 251 is used to discharge the collected second refrigerant from the water collector 250. In this way, the collected second refrigerant can be recovered to the cooling device 220 through the drain port 251, or the collected second refrigerant can be recovered to other storage devices through the drain port 251.

[0083] In a possible implementation, the cooling device 220 further includes a cooling box and a refrigerant inlet 221, and the cooling box is used to accommodate the second refrigerant. The refrigerant inlet 221 is arranged on the cooling box and is arranged opposite to the refrigerant outlet, so that the fluidity of the second refrigerant in the cooling box can be enhanced. The shape of the cooling box can be regular or irregular, and this embodiment will not be described in detail here.

[0084] It should be noted that the structure of the cooling device is not limited to the above description. For example, the cooling device 220 may also include a cooling pipe, and one end of the cooling pipe away from the heat exchanger 210 may be connected to a municipal water supply device.

[0085] In one possible implementation, continue to refer to Figure 2 The heat exchanger 210 can be a plate heat exchanger. For example, the heat exchanger 210 includes a first heat exchange inlet and a first heat exchange outlet; the first heat exchange inlet is connected to the refrigerant outlet of the liquid cooling box 110 through the first pipe 211, and the first heat exchange outlet is connected to the refrigerant inlet 221 of the liquid cooling box 110 through the second pipe 212. The first refrigerant entering the first pipe 211 flows back to the liquid cooling box 110 through the heat exchanger 210 and the second pipe 212.

[0086] A delivery pump 230 is disposed on the first pipeline 211 , and the delivery pump 230 is used to accelerate the fluidity of the first refrigerant between the heat exchanger 210 and the liquid cooling box 110 .

[0087] The heat exchange device 200 also includes a first regulating valve 213 and a second regulating valve 214; the first regulating valve 213 and the second regulating valve 214 are arranged on the first pipeline 211 and are respectively located on both sides of the delivery pump 230. For example, the first regulating valve 213 can be arranged between the delivery pump 230 and the liquid cooling device 100, and the second regulating valve 214 is arranged between the delivery pump 230 and the heat exchanger 210.

[0088] The first regulating valve 213 and the second regulating valve 214 can accurately control the flow rate of the first refrigerant in the first pipe 211. For example, the first regulating valve 213 can perform a first adjustment on the flow rate of the first refrigerant flowing in the first pipe 211, and the second regulating valve 214 can perform a second adjustment on the flow rate of the first refrigerant according to actual needs, such as increasing or decreasing the flow rate of the first refrigerant.

[0089] The first regulating valve 213 and the second regulating valve 214 can also intercept the first refrigerant in the first pipe 211. For example, during the use of the immersion liquid cooling system, the delivery pump 230 needs to be regularly repaired or replaced. Therefore, during the repair or replacement process, it is necessary to prevent the first refrigerant from circulating in the first pipe 211. Therefore, in this embodiment, a first regulating valve 213 is set between the delivery pump 230 and the liquid cooling equipment 100, and a second regulating valve 214 is set between the delivery pump 230 and the heat exchanger 210. In this way, the first refrigerant in the heat exchanger 210 can be prevented from flowing toward the delivery pump 230, and the first refrigerant in the liquid cooling box 110 can be prevented from flowing toward the delivery pump 230, thereby ensuring that the delivery pump 230 can be disassembled for repair or replacement; at the same time, the leakage of the first refrigerant can also be avoided, reducing the loss of the first refrigerant.

[0090] The heat exchange device 200 further includes a third regulating valve 215 , which is disposed on the second pipe 212 and is used to control the flow rate of the first refrigerant in the second pipe 212 .

[0091] In one possible implementation, continue to refer to Figure 4 The system also includes a cabinet 300, and the heat exchange device 200 and the liquid cooling device 100 are arranged in the cabinet 300. In this way, the heat exchange device 200 and the liquid cooling device 100 can be integrated into one. Compared with the solution in the related art that the heat exchange device 200 and the liquid cooling device 100 are sold separately and the customer needs to reassemble the heat exchange device 200 and the liquid cooling device 100 after purchase, this embodiment integrates the heat exchange device 200 and the liquid cooling device 100 into the same cabinet 300, which can realize the integrated delivery of the immersion liquid cooling system and solve the problems of complex procurement and long construction period for customers. In addition, this embodiment integrates the heat exchange device 200 and the liquid cooling device 100 into the same cabinet 300, which can also reduce the floor space of the immersion liquid cooling system in the related art and save the floor space of the computer room of the data center.

[0092] In one example, the cabinet 300 has relatively independent first accommodating space 350 and second accommodating space 360. For example, a partition 380 can be set in the cabinet 300, and the partition 380 divides the cabinet 300 into mutually independent first accommodating space 350 and second accommodating space 360, wherein the liquid cooling device 100 is set in the first accommodating space 350, and the heat exchange device 200 is set in the second accommodating space 360. In this way, mutual interference between the heat exchange device 200 and the liquid cooling device 100 can be prevented.

[0093] In another example, the cabinet 300 has a relatively independently arranged first accommodating space 350, a second accommodating space 360 ​​and a third accommodating space 370. For example, two partitions 380 can be arranged in the cabinet 300, and the two partitions 380 divide the cabinet 300 into a first accommodating space 350, a second accommodating space 360 ​​and a third accommodating space 370 that are independent of each other, wherein the liquid cooling device 100 is arranged in the first accommodating space 350, the heat exchange device 200 is arranged in the second accommodating space 360, and the uninterruptible power supply 500 is arranged in the third accommodating space 370, and the uninterruptible power supply 500 is electrically connected to the object to be cooled 120 and the heat exchange device 200, respectively, to prevent the object to be cooled 120 and the heat exchange device 200 from failing to work normally after a municipal power outage. The third accommodating space 370 may be disposed on a side of the first accommodating space 350 away from the second accommodating space 360 ​​, or may be disposed on a side of the second accommodating space 360 ​​away from the first accommodating space 350 .

[0094] In this example, a second heat dissipation fan 510 is also provided in the third accommodating space 370. The second heat dissipation fan 510 is used to conduct the heat generated during the operation of the uninterruptible power supply 500 to the outside of the cabinet 300, thereby preventing the above-mentioned heat from accumulating in the cabinet 300 and improving the safety of the immersion liquid cooling system.

[0095] In a possible implementation, a first heat dissipation fan 240 is further disposed in the first accommodation space 350. The first heat dissipation fan 240 is used to accelerate the air flow in the first accommodation space 350, accelerate the heat exchange between the heat exchanger 210 and the air, enhance the heat exchange capacity of the heat exchanger 210, and further increase the heat exchange rate between the heat exchanger 210 and the first refrigerant. In one example, the first heat dissipation fan 240 can be disposed adjacent to the heat exchanger 210. For example, taking the orientation shown in the figure as an example, the first heat dissipation fan 240 is disposed in front of the heat exchanger 210.

[0096] It should be noted that in this embodiment, the number of the first heat dissipation fans 240 may be one or more. For example, the plurality of first heat dissipation fans 240 are arranged at intervals along a direction perpendicular to the bottom surface of the cabinet 300 .

[0097] In order to prevent the air after heat exchange from gathering in the first accommodation space 350, at least one air outlet is provided at the position of the cabinet 300 corresponding to the first accommodation space 350. For example, there is one air outlet, which can be arranged opposite to the first heat dissipation fan 240, so that the air flow in the first accommodation space 350 can be ensured. For another example, there are multiple air outlets, and illustratively, there are three air outlets. In order to facilitate the description of the position of the air outlets, the air outlets may be divided into a first air outlet 310, a second air outlet 320 and a third air outlet 330, wherein the second air outlet 320 is arranged opposite to the first heat dissipation fan, the side where the first air outlet 310 is located is adjacent to and perpendicular to the side where the second air outlet 320 is located, and the third air outlet 330 is arranged on the top surface of the cabinet 300.

[0098] by Figure 1 Take the orientation shown as an example. Figure 1 In the middle Y direction, the first cooling fan 240 is located in front of the heat exchanger 210, and the second air outlet 320 can be arranged behind the heat exchanger 210, that is, the second air outlet 320 is arranged on the rear side of the cabinet 300, and accordingly, the first air outlet 310 is arranged on the left side of the cabinet 300, that is, the first air outlet 310 is arranged on the side of the cabinet 300 away from the liquid cooling device 100.

[0099] In this embodiment, three air outlets are provided on the cabinet 300 to accelerate the speed of air flow in the first accommodating space 350, thereby ensuring the cooling effect of the immersion liquid cooling system.

[0100] In this embodiment, a filter or a louver can be provided on each air outlet. When a filter is provided on the air outlet, the filter can be used to prevent external impurities from entering the first accommodation space 350, thereby ensuring the safety of the heat exchanger 210 or other components located in the first accommodation space 350. When a louver is provided on the air outlet, the opening degree of the louver can be adjusted to reasonably adjust the opening state of each air outlet. For example, the opening degree of the louver on the first air outlet 310, the louver on the second air outlet 320, and the louver on the third air outlet 330 can be adjusted to reasonably adjust the opening state of the first air outlet 310, the second air outlet 320, and the third air outlet 330.

[0101] It should be noted that the opening states of the first air outlet 310, the second air outlet 320 and the third air outlet 330 are also related to the location of the immersion liquid cooling system in the installation space (such as a room), wherein one of the walls of the room has an air inlet window 600 and an air outlet window 700. In one example, Figure 5 and Figure 6As shown, the side where the first air outlet 310 is located in the cabinet 300 of the immersion liquid cooling system is against the wall with the air inlet window 600 and the air outlet window 700, so that the first air outlet 310 is located at the air outlet window 700. At this time, the second air outlet 320 and the third air outlet 330 are closed. In this way, the heat of the cabinet 300 can be directly discharged from the room through the first air outlet 310 and the air outlet window 700.

[0102] In another example, the side of the cabinet 300 of the immersion liquid cooling system where the second air outlet 320 is located is arranged against the wall with the air inlet window 600 and the air outlet window 700, so that the second air outlet 320 is located at the air outlet window 700. At this time, the first air outlet 310 and the third air outlet 330 are closed, so that the heat of the cabinet 300 can be directly discharged from the room through the second air outlet 320 and the air outlet window 700. Or, as Figure 7 and Figure 8 As shown, the cabinet 300 of the immersion liquid cooling system is spaced apart from the wall having an air inlet window 600 and an air outlet window 700, but the second air outlet 320 of the cabinet 300 faces the air outlet window and is opposite to the air outlet window 700. In this way, the heat of the cabinet 300 is directly discharged from the room through the space inside the cabinet 300, the second air outlet 320 and the air outlet window 700.

[0103] In another example, Fig. 9 and Fig.10 As shown, when the sides where the first air outlet 310 and the second air outlet 320 are located are not set against the wall, the first air outlet 310 and the second air outlet 320 are closed and the third air outlet 330 is opened, but an air supply duct 390 is required to be set between the third air outlet 330 and the air outlet window 700. In this way, the heat generated in the cabinet 300 can be discharged from the room through the third air outlet 330, the air supply duct 390 and the air outlet window 700.

[0104] In a possible implementation, Figure 2 and Fig.11 As shown, the immersion liquid cooling system also includes a controller 400 and a temperature detection component. The working states of the heat exchanger 210 and the first heat dissipation fan 240 in the immersion liquid cooling system need to be related to the temperature of the first refrigerant in the liquid cooling equipment 100, and the working state of the cooling device 220 needs to be related to the temperature of the second refrigerant. Therefore, a controller 400 and a temperature detection component are provided in this embodiment. The controller 400 receives the temperature value of the temperature detection component and controls the working states of the heat exchanger 210, the first heat dissipation fan 240 and the cooling device 220 according to the temperature value.

[0105] In one example, the temperature detection component includes a first temperature sensor 111 and a second temperature sensor 112 disposed in a liquid cooling box 110. The first temperature sensor 111 is used to detect the temperature of the object to be cooled 120. In order to more accurately characterize the temperature of the object to be cooled 120, the first temperature sensor 111 can be used to detect the temperature of the chip 121 of the object to be cooled 120, and the second temperature sensor 112 is used to detect the temperature of the first refrigerant. The controller 400 is also connected to the first regulating valve 213, the second regulating valve 214 and the third regulating valve 215 respectively. The controller 400 is used to control the opening of the first regulating valve 213, the second regulating valve 214 and the third regulating valve 215 according to the detected temperatures of the first temperature sensor 111 and the second temperature sensor 112. For example, the first temperature sensor 111 detects that the temperature of the object to be cooled 120 is higher than the set value (for example, the set value is 50°C), and the first temperature sensor 111 transmits the temperature to the controller 400. The controller 400 compares the temperature with the set value, and the controller 400 can send an action instruction to the first regulating valve 213, the second regulating valve 214, and the third regulating valve 215 to increase the opening of the first regulating valve 213, the second regulating valve 214, and the third regulating valve 215 to increase the circulation speed of the first refrigerant between the heat exchanger 210 and the liquid cooling device 100, so that the temperature of the first refrigerant and the temperature of the object to be cooled 120 are controlled within the target allowable range. For another example, the controller 400 can also control the speed of the delivery pump 230 according to the detected temperature of the first temperature sensor 111 and the second temperature sensor 112.

[0106] In another example, a fourth regulating valve 222 is provided at the refrigerant inlet 221 of the cooling device 220, and the temperature detection component also includes a third temperature sensor 223 and a fourth temperature sensor 224; the third temperature sensor 223 is used to detect the first temperature at the refrigerant inlet 221 of the cooling device 220, and the fourth temperature sensor 224 is used to detect the second temperature at the refrigerant outlet of the cooling device 220; the controller 400 is respectively connected to the fourth regulating valve 222, the third temperature sensor 223 and the fourth temperature sensor 224, and is used to control the opening size of the fourth regulating valve 222 according to the first temperature detected by the third temperature sensor 223 and the second temperature detected by the fourth temperature sensor 224, thereby adjusting the flow rate and flow speed of the second refrigerant entering the cooling device 220.

[0107] In another example, the temperature detection component also includes a fifth temperature sensor 241 and a sixth temperature sensor 242 arranged in the first accommodating space 350, the fifth temperature sensor 241 is used to detect the inlet air temperature of the first cooling fan 240, and the sixth temperature sensor 242 is used to detect the outlet air temperature of the heat exchanger 210 away from the first cooling fan 240; that is, the fifth temperature sensor 241 is used to detect the temperature of the air before entering the first cooling fan 240, and the sixth temperature sensor 242 is used to detect the temperature of the air after heat exchange through the heat exchanger 210.

[0108] The controller 400 is also electrically connected to the first cooling fan 240 , and is used to control the rotation speed of the first cooling fan 240 according to the detected temperatures of the fifth temperature sensor 241 and the sixth temperature sensor 242 , and adjust the working state of the first cooling fan 240 in real time.

[0109] In some embodiments, a touch screen 340 may also be provided on the cabinet 300 , and the touch screen 340 is used to display control information or detection information of each sensor.

[0110] An embodiment of the present application also provides a control method for an immersion liquid cooling system, which is applied to the immersion liquid cooling system in the above embodiment. Specifically, the immersion liquid cooling system includes a liquid cooling device 100 and a heat exchange device 200. The liquid cooling device 100 has an object to be cooled 120 and a first refrigerant that immerses the object to be cooled 120, wherein the first refrigerant is used to cool the object to be cooled 120, and the heat exchange device 200 is used to cool the first refrigerant after absorbing the object to be cooled 120.

[0111] See also Fig.12 , the control method comprises the following steps:

[0112] Step S201: obtaining the actual temperature of the object to be cooled and the actual temperature of the first refrigerant.

[0113] The execution subject in the embodiment of the present application may be a controller of the immersion liquid cooling system, and the controller may be implemented by software or by a combination of software and hardware.

[0114] In this step, the actual temperature can be obtained through a temperature sensor. For example, a first temperature sensor can be set on the object to be cooled, and the first temperature sensor is used to obtain the actual temperature of the chip of the object to be cooled; a first temperature sensor is set in the liquid cooling box, and the actual temperature of the first refrigerant is obtained by using the first temperature sensor.

[0115] The number of objects to be cooled may be one or more. When the number of objects to be cooled is one, the actual temperature of the single cooling object may be directly obtained. When the number of objects to be cooled is more than one, the actual temperature of the object to be cooled and the actual temperature of the first refrigerant may be obtained in the following manner.

[0116] Exemplarily, the actual temperature of each object to be cooled is acquired, and the maximum value and the minimum value of the actual temperatures of all objects to be cooled are obtained.

[0117] The actual temperature of the object to be cooled is determined according to the difference between the maximum value of the actual temperature of all the objects to be cooled and the minimum value of the actual temperature. For example, if the difference between the maximum value and the minimum value of the actual temperature of the object to be cooled is less than 3°C, the average value of the actual temperature of all the objects to be cooled can be used as the actual temperature value of the object to be cooled. For another example, if the difference between the maximum value and the minimum value of the actual temperature of the object to be cooled is greater than or equal to 3°C, the minimum value of the actual temperature is used as the actual temperature value of the object to be cooled.

[0118] The actual temperature of the first refrigerant at multiple positions in the liquid cooling box is obtained, and the maximum and minimum values ​​of the actual temperature of the first refrigerant at all positions are obtained. For example, multiple first temperature sensors are set in the liquid cooling box to obtain the actual temperature of the first refrigerant at multiple positions in the liquid cooling box.

[0119] The actual temperature of the first refrigerant is determined according to the maximum value of the actual temperature of the first refrigerant and the minimum value of the actual temperature of the first refrigerant. For example, if the difference between the maximum value and the minimum value of the actual temperature of the first refrigerant is less than 3°C, the average value of all values ​​of the actual temperature of the first refrigerant is taken as the actual temperature of the first refrigerant. For another example, if the difference between the maximum value and the minimum value of the actual temperature of the first refrigerant is greater than or equal to 3°C, the highest value of the actual temperature of the first refrigerant is taken as the actual temperature value of the first refrigerant.

[0120] Step S202: Determine the current environmental state of the object to be cooled according to the actual temperature of the object to be cooled and the actual temperature of the first refrigerant.

[0121] This step can determine whether the environmental state of the object to be cooled is a supercooling state or a non-supercooling state according to the actual temperature of the object to be cooled and the actual temperature of the first refrigerant.

[0122] Step S203: Control the working state of the heat exchanger and the cooling device according to the current environmental state of the object to be cooled.

[0123] The embodiment of the present application determines the current environmental state of the object to be cooled based on the actual temperature of the object to be cooled and the actual temperature of the first refrigerant. Then, based on the current environmental state of the object to be cooled, the working state of the heat exchanger and the cooling device is controlled in a targeted manner. In this way, waste of resources can be avoided and the function of economical energy saving can be achieved.

[0124] exist Fig.12 Based on the embodiment shown below, combined with Fig.13 The control method of the above-mentioned immersion liquid cooling system is described in detail.

[0125] Step S301: obtaining the actual temperature of the object to be cooled and the actual temperature of the first refrigerant.

[0126] It should be noted that the execution process of step S301 can refer to the execution process of step S201, which will not be repeated here.

[0127] Step S302: determining a temperature difference between the actual temperature of the object to be cooled and the actual temperature of the first refrigerant according to the actual temperature of the object to be cooled and the actual temperature of the first refrigerant.

[0128] Step S303: determining, based on the temperature difference and the first difference threshold, whether the current environmental state of the object to be cooled is an overcooling state or a non-overcooling state.

[0129] The difference threshold may be preset and entered in advance by the user, or may be obtained by querying after establishing a communication connection with a local database or cloud data.

[0130] If the temperature difference is greater than the difference threshold, it is determined that the temperature of the first refrigerant is relatively low, and the first refrigerant's own heat can be used to cool the cooling device, thereby determining that the current environmental state of the object to be cooled is an overcooled state.

[0131] If the temperature difference is less than the difference threshold, it is determined that the temperature of the first refrigerant is high and needs to be cooled by external heat exchange equipment, and then it is determined that the current environmental state of the object to be cooled is a non-supercooling state.

[0132] Step S304: When the current environment state of the object to be cooled is an overcooling state, the heat exchanger and the cooling device are controlled to be in a non-working state.

[0133] In this step, the heat exchanger and the cooling device are in a paused state, mainly relying on the first refrigerant's own heat to exchange heat with the object to be cooled. In this way, on the one hand, it can avoid the waste of resources and achieve the function of economic energy saving; on the other hand, it can prevent the temperature of the object to be cooled from being too low, affecting the normal use of the object to be cooled.

[0134] Step S305: When the current environment state of the object to be cooled is a non-supercooling state, the heat exchanger and the cooling device are controlled to be in a working state, or the heat exchanger is controlled to be in a working state and the cooling device is controlled to be in a non-working state.

[0135] Specifically, the working states of the heat exchanger and the cooling device can be adjusted according to the temperatures detected by various temperature sensors, so as to minimize the energy consumption of the immersion liquid cooling system, thereby achieving maximum energy saving.

[0136] As a further improvement of the above embodiment, considering that the immersion liquid cooling system also includes a first heat dissipation fan, the first heat dissipation fan is used to dissipate heat from the heat exchanger, and then dissipate heat from the first refrigerant flowing into the heat exchanger, affecting the temperature of the first refrigerant. Therefore, it is necessary to use the air temperature in the first accommodating space of the cabinet and the temperature of the second refrigerant entering the cooling device as a basis to determine whether it is necessary to start the first heat dissipation fan.

[0137] In one example, step S305 further includes the following steps: Step S3051: obtaining the air inlet temperature of the air inlet side of the first cooling fan.

[0138] In this step, the inlet air temperature of the first heat dissipation fan at the inlet air side is acquired in real time through the fifth temperature sensor at the inlet air side of the first heat dissipation fan.

[0139] Step S3052: According to the air inlet temperature and the first temperature threshold, the heat exchanger, the cooling device and the first cooling fan are controlled to be in working state. The first temperature threshold may be preset and entered by the user in advance, or may be obtained by querying after communicating with the local database or cloud data.

[0140] For example, if the inlet air temperature is greater than the first temperature threshold, it means that the temperature of the inlet side entering the first cooling fan is too high, and the air with a higher temperature is difficult to exchange heat with the first refrigerant entering the heat exchanger, and then it is difficult to lower the temperature of the first refrigerant. At this time, the heat exchanger, the cooling device and the first cooling fan are all required to be in working state to increase the heat exchange efficiency between the heat exchanger and the air and the heat exchange efficiency between the cooling device and the heat exchanger.

[0141] After the heat exchanger, the first cooling fan and the cooling device continue to work for a period of time, the temperature of the first refrigerant may drop to the target allowable range. At this time, if the heat exchanger, the first cooling fan and the cooling device continue to work, it will cause a waste of resources. Therefore, this embodiment also includes the following steps:

[0142] Step S3053: Obtain the first temperature at the refrigerant inlet of the cooling device.

[0143] In this step, the second temperature of the refrigerant inlet of the cooling device can be obtained by a third temperature sensor disposed at the refrigerant inlet of the cooling device.

[0144] Step S3054: According to the first temperature and the second temperature threshold, the first cooling fan is controlled to be in an inoperative state, and the heat exchanger and the cooling device are controlled to be in an operative state.

[0145] For example, if the first temperature is less than the first temperature threshold, it means that the first temperature of the refrigerant inlet entering the cooling device is lower, and the cooling device can better cool the first refrigerant in the heat exchanger. At this time, the first cooling fan can be controlled to be in an inoperative state, and the heat exchanger and the cooling device can be used to exchange heat with the first refrigerant in the heat exchanger.

[0146] The above steps are to determine whether the first heat dissipation fan is in working state when the heat exchanger and the cooling device are both in working state.

[0147] In another example, step S305 further includes the following steps:

[0148] Step S3055: Acquire the air inlet temperature of the air inlet side of the first cooling fan.

[0149] It should be noted that the execution process of step S3055 can refer to the execution process of step S3051, which will not be repeated here.

[0150] Step S3056: According to the inlet air temperature and the third temperature threshold, the first heat dissipation fan and the cooling device are controlled to be in an inoperative state, and the heat exchanger is controlled to be in an operative state, wherein the third temperature threshold is less than the first temperature threshold.

[0151] This step is to determine whether the first cooling fan is in working state when the heat exchanger is in working state and the cooling device is in non-working state.

[0152] In this embodiment, the third temperature threshold represents that the air temperature is low enough. At this time, the fourth regulating valve of the first heat dissipation fan and the cooling device can be closed, so that the first heat dissipation fan and the cooling device are in an inoperative state. Relying on the operation of the heat exchanger and the heat exchange by air contact, the immersion liquid cooling system can be operated with minimized power to achieve maximum energy saving.

[0153] The present application also provides a control device 10 for an immersion liquid cooling system. Fig.14 The device 10 includes: an acquisition module 11, a determination module 12 and a control module 13.

[0154] The acquisition module 11 is used to acquire the actual temperature of the object to be cooled and the actual temperature of the first refrigerant.

[0155] The determination module 12 is used to determine the current environmental state of the object to be cooled according to the actual temperature of the object to be cooled and the actual temperature of the first refrigerant.

[0156] The control module 13 is used to control the working state of the heat exchanger and the cooling device according to the current environmental state of the object to be cooled.
