Summary of the Invention

Problems to be Solved by the Invention

[0006] According to one aspect of the present disclosure, it is for providing a liquid immersion cooling module capable of effectively maintaining the cooling performance of a cooling fluid through the flow of the cooling fluid in a separate space where the inflow direction and the outflow direction of the cooling fluid for cooling a battery cell are different from each other.

[0007] Another aspect of this disclosure provides a control method for an immersion cooling module that can maximize the cooling performance of a cooling fluid by appropriately controlling the flow and direction of the cooling fluid in separate spaces where the inflow and outflow directions of the cooling fluid for cooling battery cells are different from each other. [Means for solving the problem]

[0008] An immersion cooling module according to one embodiment of the present disclosure may include: a housing portion containing a cooling fluid and impregnated with battery cells; a support portion that divides the housing portion into a first space on one side containing a first cooling fluid and a second space on the other side containing a second cooling fluid, and to which at least one of the battery cells is coupled; and a circulator that is coupled to and driven by the support portion so that the first space on one side of the support portion and the second space on the other side are in communication, and so that the first cooling fluid and the second cooling fluid can flow to each other.

[0009] Here, the battery cell is coupled to the support portion, but a porous moisture-absorbing member may be further included between the coupling surface of the support portion and the battery cell.

[0010] Furthermore, the circulator may include a first screw formed in the region of the first space, a second screw formed in the region of the second space, a rotating shaft to which the first screw and the second screw are coupled, a support plate to which the rotating shaft is rotatably coupled to a drive device and to which the drive device is coupled to the support portion, and which has at least one through hole formed therein that allows the first space and the second space to communicate.

[0011] Furthermore, the housing may also include a first inlet at one end of the first space into which the first cooling fluid flows, a first outlet at the other end of the first space into which the first cooling fluid flows, a second inlet at one end of the second space in the direction in which the first outlet was formed into which the second cooling fluid flows, and a second outlet at the other end of the second space in the direction in which the first inlet was formed into which the second cooling fluid flows.

[0012] Furthermore, the through holes in the support plate may be formed in a circular shape in multiple locations in the circumferential direction of the support plate.

[0013] A control method for an immersion cooling module according to one embodiment of the present disclosure includes the steps of: measuring the temperature on the first space side and the temperature on the second space side of a plurality of circulators that connect a first space containing a first cooling fluid and a second space containing a second cooling fluid; determining whether the temperature difference between the first space side and the second space side exceeds a predetermined threshold; and, if the temperature difference between the first space side and the second space side exceeds the predetermined threshold, moving the first circulator at the location where the temperature difference was measured to the first or second cooling on the first or second space side where the temperature is even lower. The procedure may include the steps of: driving the first circulator to cause the fluid to flow to a second or first space with a higher temperature; and driving a second circulator adjacent to the direction in which the second or first cooling fluid flows from the second inlet to the second outlet, or from the first inlet to the first outlet, in the second or first space with a higher temperature, to cause the second or first cooling fluid to flow from the second or first space with a higher temperature to the first or second space with a lower temperature.

[0014] Here, if the temperature difference between the first space and the second space exceeds a predetermined threshold, the step of driving the first circulator at the location where the temperature difference was measured to flow the first or second cooling fluid from the first space or the second space, which has a lower temperature, to the second space or the first space, which has a higher temperature, may further include the step of selecting the location where the temperature difference is largest, if there are multiple locations where the temperature difference was measured, when the temperature difference between the first space and the second space exceeds a predetermined threshold.

[0015] Furthermore, the step of determining whether the temperature difference between the first space and the second space exceeds a predetermined threshold may further include the step of measuring the temperature of the first cooling fluid in the first space and the temperature of the second cooling fluid in the second space in real time at multiple locations where a circulator connecting the first space and the second space is coupled, and measuring the difference between them.

[0016] The features and advantages of this disclosure will become more apparent in the subsequent detailed description based on the accompanying drawings.

[0017] Prior to this, terms or words used in this specification and claims should not be interpreted in their ordinary or lexicographical sense, but rather in a sense and concept consistent with the technical idea of ​​this disclosure, in accordance with the principle that an inventor may appropriately define the concept of a term in order to best describe his invention. [Effects of the Invention]

[0018] According to one embodiment of the present disclosure, there is an effect that the cooling efficiency can be maximized depending on the flow direction of the cooling fluid.

[0019] Furthermore, by adjusting the flow direction of the cooling fluid, it is possible to control the rise in the temperature of the cooling fluid and the object being cooled, as well as adjust the flow of the cooling fluid according to the degree of cooling.

[0020] Furthermore, by improving the cooling effect according to the flow direction of the cooling fluid and effectively controlling the flow direction of the cooling fluid to maximize cooling efficiency, the overall energy efficiency of the device is increased, reducing power consumption and thus reducing carbon emissions from the operation of the related devices.

[0026] Hereinafter, an embodiment of the present disclosure will be described in detail with reference to the accompanying drawings.

[0027] Figure 1 is a schematic cross-sectional view of an immersion cooling module according to one embodiment of the present disclosure, Figure 2 is an enlarged view of portion A in Figure 1, and Figure 3 is a schematic diagram of the configuration of a circulator 50 according to one embodiment of the present disclosure.

[0028] An immersion cooling module according to one embodiment of the present disclosure may include: a housing 10 in which cooling fluids L1 and L2 are contained and a battery cell 20 is impregnated; a support 40 which divides the housing 10 into a first space 10a on one side in which the first cooling fluid L1 is contained and a second space 10b on the other side in which the second cooling fluid L2 is contained, and to which at least one of the battery cells 20 is connected; and a circulator 50 which is connected to the support 40 so as to communicate between the first space 10a and the second space 10b of the support 40 and is driven so as to allow the first cooling fluid L1 and the second cooling fluid L2 to flow to each other.

[0029] As shown in Figure 1, the housing section 10 contains cooling fluids L1 and L2 and forms a space into which the battery cell 20 is impregnated. Here, a battery cell 20 is used as an example to illustrate the object impregnated with cooling fluids L1 and L2, but considering the size and specifications of the liquid immersion cooling module, it can be applied to data centers and other facilities containing large equipment or systems, rather than just battery cells 20.

[0030] As shown in Figure 1, the support portion 40 can be connected inside the housing portion 10 so as to divide the upper and lower spaces of the housing portion 10. The connection configuration of the support portion 40 or the configuration of the support portion 40 is not limited to those shown, but can be appropriately arranged so as to form flows of cooling fluids L1 and L2 in the two spaces.

[0031] In one embodiment of the present disclosure, the support portion 40 is described as being connected so as to divide the lower space of the support portion 40 into a first space 10a and the upper space into a second space 10b. The first space 10a and the second space 10b are formed as physically separated spaces, and cooling fluids L1 and L2, i.e., the first cooling fluid L1 and the second cooling fluid L2, can flow individually into each space.

[0032] In other words, as shown in Figure 1, in the first space 10a, a first inlet 11 into which the first cooling fluid L1 flows in and a first outlet 12 into which the first cooling fluid L1 flows out are formed on one side and the other side, respectively, thereby forming the flow direction of the cooling fluids L1 and L2.

[0033] Separately, in the second space 10b, an inlet and an outlet can be formed on opposite sides from the first space 10a. Specifically, a second inlet 13 can be formed on the opposite side of the first inlet 11 of the first space 10a, through which the second cooling fluid L2 flows into the second space 10b, and a second outlet 14 can be formed on the opposite side of the first outlet 12 of the first space 10a, through which the second cooling fluid flows out into the second space 10b.

[0034] While it is possible to apply different types of cooling fluids L1 and L2 to the first and second cooling fluids L1 and L2, it is also possible to apply the same type of cooling fluid L1 and L2.

[0035] When different cooling fluids L1 and L2 are applied, relevant conditions such as the physical arrangement of the first space 10a and the second space 10b, the mixability between the fluids, or the difference in their specific gravity can be appropriately selected and applied to ensure that the first cooling fluid L1 and the second cooling fluid L2 mix and flow smoothly.

[0036] The cooling fluids L1 and L2 can be non-conductive fluids to prevent electricity from flowing through the impregnated electronic product, battery cell 20, server, etc. For example, the cooling fluids L1 and L2 may include a base oil. The base oil may include mineral oil, polyalphaolefin (PAO), and / or ester base oil. However, the cooling fluids L1 and L2 of this disclosure are not limited to these, and any fluid capable of cooling a battery cell can be included.

[0037] The support portion 40 can be formed to divide the space inside the housing portion 10 into a first space 10a and a second space 10b, and to connect the battery cell 20. In this disclosure, an example is shown in which the battery cell 20 is connected to the support portion 40, but in the case of other devices such as coolable electronic devices or servers, they can be physically fixedly connected to the support portion 40 so that immersion cooling is effectively performed inside the housing portion 10.

[0038] Since the battery cells 20 to be cooled are connected to the support portion 40 and positioned at each fixed location, the flow direction of the first cooling fluid L1 and the second cooling fluid L2 can be appropriately adjusted according to the temperature or flow state at each location of the cooling fluids L1 and L2, or a mixed flow of the cooling fluids L1 and L2 can be induced to effectively cool the battery cells 20 positioned at each location.

[0039] Here, a porous moisture-absorbing member 30 can be attached to the joint surface where the battery cell 20 and the support part 40 are joined. By attaching the porous moisture-absorbing member 30, a buffering effect is possible on the joint between the support part 40 and the battery cell 20, so that it can appropriately respond to the expansion or physical deformation of the battery cell 20. In addition, the cooling fluids L1 and L2 are naturally absorbed by the porous moisture-absorbing member 30, cooling the outer surface of the battery cell 20, and the battery cell 20 can be cooled again through the latent heat of vaporization of the cooling fluids L1 and L2 due to the heat generated by the battery cell 20.

[0040] The circulator 50 can be driven by being coupled to the support portion 40 at at least one point so as to cause the first cooling fluid L1 and the second cooling fluid L2 in the first space 10a and the second space 10b, which are partitioned by the support portion 40, to mix and flow with each other.

[0041] As shown in Figure 2, the circulator 50 may include a first screw 53 impregnated in a first cooling fluid L1 in a first space 10a and a second screw 54 impregnated in a second cooling fluid L2 in a second space 10b.

[0042] The first screw 53 and the second screw 54 are connected to a rotating shaft 51a, and the rotating shaft 51a is connected to a drive device 51 and rotated, thereby allowing the flow direction of the first cooling fluid L1 and the second cooling fluid L2 to be determined according to the direction of rotation.

[0043] Specifically, as shown in Figure 3, the circulator 50 may include a first screw 53 formed in the region of the first space 10a, a second screw 54 formed in the region of the second space 10b, a rotating shaft 51a to which the first screw 53 and the second screw 54 are coupled, and a support plate 52 to which the rotating shaft 51a is rotatably coupled to a drive unit 51, the drive unit 51 is coupled to a support unit 40, and at least one through hole 52a is formed so that the first space 10a and the second space 10b are in communication.

[0044] In other words, the support plate 52 is connected to the support portion 40 at the boundary between the first space 10a and the second space 10b, and the drive device 51 can be connected to the support plate 52. The drive device 51 may include, for example, a motor drive device, and various other rotary drive devices can be applied to rotate the rotating shaft 51a.

[0045] A drive unit 51 is coupled to a support plate 52, and the drive unit 51 can be rotatably coupled to a rotating shaft 51a so as to rotate the first screw 53 and the second screw 54.

[0046] By simultaneously driving the first screw 53 and the second screw 54 in the direction of rotation of the rotating shaft 51a, the first cooling fluid L1 can flow from the first space 10a to the second space 10b, or the second cooling fluid L2 can flow from the second space 10b to the first space 10a in the opposite direction.

[0047] The direction of movement of the cooling fluid is formed to be the same according to the rotation direction of the first screw 53 and the second screw 54, and the flow of the cooling fluids L1 and L2 can be controlled by adjusting the rotation direction of one rotating shaft 51a.

[0048] As shown in Figure 3, the support plate 52 can have at least one through-hole 52a that connects the first space 10a and the second space 10b when the first screw 53 and the second screw 54 are driven and the cooling fluids L1 and L2 flow. By adjusting the amount or rate at which the cooling fluids L1 and L2 flow in per unit time according to the shape and size of the through-hole 52a, the cooling efficiency can be maximized.

[0049] The through holes 52a in the support plate 52 can be formed by a plurality of circular through holes 52a spaced apart in the circumferential direction of the support plate 52, and it goes without saying that they can be formed into through holes 52a of different shapes by making their diameters different from each other. Furthermore, the cooling efficiency can be improved by determining the appropriate size and number of through holes 52a according to the placement position of the circulator 50, that is, according to the temperature of the cooling fluids L1 and L2 according to the flow of the first cooling fluid L1 and the second cooling fluid L2, and according to the degree of heat generation of the battery cells 20 connected to each part of the support part 40.

[0050] By adjusting the area of ​​the through-holes 52a through which the cooling fluids L1 and L2 mutually flow between the first space 10a and the second space 10b, the flow velocity of the cooling fluids L1 and L2 passing through the support plate 52 per unit time can be adjusted, and by adjusting the total area L of the through-holes 52a, the total amount of cooling fluids L1 and L2 passing through per unit time can be adjusted.

[0051] Figure 4 is a flowchart of a control method for an immersion cooling module according to one embodiment of the present disclosure, Figure 5 is a first operation flowchart of a control method for an immersion cooling module according to one embodiment of the present disclosure, and Figure 6 is a second operation flowchart of a control method for an immersion cooling module according to one embodiment of the present disclosure.

[0052] A control method for an immersion cooling module according to one embodiment of the present disclosure includes the steps of: measuring the temperature on the first space 10a side and the temperature on the second space 10b side of a plurality of circulators 50 that connect a first space 10a containing a first cooling fluid L1 and a second space 10b containing a second cooling fluid L2; determining whether the temperature difference between the first space 10a side and the second space 10b side exceeds a predetermined threshold; and, if the temperature difference between the first space 10a side and the second space 10b side exceeds a predetermined threshold, moving the first circulator 50a at the location where the temperature difference was measured to the first or second space 10b side, which has an even lower temperature. The method may include the steps of: driving the cooling fluids L1 and L2 to flow towards the second space 10b or the first space 10a, where the temperature is higher; and driving a second circulator 50b adjacent to the second space 10b or the first space 10a, where the second cooling fluid L2 or the first cooling fluid L1 flows in the direction from the second inlet 13 to the second outlet 14, or from the first inlet 11 to the first outlet 12, so that the second cooling fluid L2 or the first cooling fluid L1 flows from the second space 10b or the first space 10a, where the temperature is higher, to the first space 10a or the second space 10b, where the temperature is lower.

[0053] As shown in Figure 5, the first step is to measure the temperature on the side of the first space 10a and the side of the second space 10b of at least one circulator 50 that connects the first space 10a containing the first cooling fluid L1 and the second space 10b containing the second cooling fluid L2, respectively, via the first temperature sensor T1 and the second temperature sensor T2.

[0054] In one embodiment of this disclosure, the flow direction of the first cooling fluid L1 in the first space 10a and the flow direction of the second cooling fluid L2 in the second space 10b can be designed to be opposite to each other. The temperature of the cooling fluids L1 and L2 is lowest at the inlet, and as the fluids move in the direction of flow, the temperature of the cooling fluids L1 and L2 gradually increases while cooling the battery cell 20, which is the object to be cooled, and the cooling efficiency decreases.

[0055] Therefore, by causing the first cooling fluid L1 and the second cooling fluid L2 to flow in opposite directions in the first space 10a and the second space 10b, respectively, the cooling efficiency of the battery cell 20 impregnated in the housing 10 can be maximized.

[0056] By measuring the temperature difference between the first cooling fluid L1 and the second cooling fluid L2 at the point where the circulator 50 is connected so that the first space 10a and the second space 10b are in communication, the heat generation state or cooling efficiency state of the battery cell 20 can be effectively checked. Furthermore, since the temperature difference at the location where the circulator 50 is placed can be measured, it would be appropriate to consider this when placing the circulator 50 and install and connect it at an appropriate position and interval.

[0057] Next is the step of determining whether the measured temperature difference between the first space 10a and the second space 10b exceeds a predetermined threshold.

[0058] The temperature range of the first cooling fluid L1 depending on the flow direction of the first cooling fluid L1 and the temperature range of the second cooling fluid L2 depending on the flow direction of the second cooling fluid L2 can be formed within a predetermined range. Therefore, it can be seen that if the mutual temperature difference between the first cooling fluid L1 and the second cooling fluid L2 at each location exceeds a threshold, the heat generation of the battery cell 20 as a whole or at a specific location at that location will increase rapidly. Because the battery cell 20 spans both the first space 10a and the second space 10b, the temperature difference between the first cooling fluid L1 and the second cooling fluid L2 in the first space 10a and the second space 10b can increase rapidly due to the heat generation problem at locations close to the interface.

[0059] It goes without saying that the threshold for the temperature difference between the first space 10a and the second space 10b can be set to be different at each point in the direction in which the cooling fluid flows.

[0060] If the measured temperature difference between the first space 10a and the second space 10b exceeds a predetermined threshold, the first circulator 50a can be activated at the location where the temperature difference is measured to exceed the threshold.

[0061] In other words, the first circulator 50a at the location where the temperature difference is measured can be driven to cause the first cooling fluid L1 or the second cooling fluid L2 from the first space 10a side or the second space 10b side, where the temperature is even lower, to flow to the second space 10b side or the first space 10a side, where the temperature is even higher.

[0062] By directing the cooling fluids L1 and L2 from the lower-temperature space to the relatively higher-temperature space, the temperature difference between the first space 10a and the second space 10b can be minimized, maintaining a cooling balance and effectively addressing heat generation at specific locations.

[0063] Next, a second circulator 50b adjacent to the second space 10b side or the first space 10a side, where the temperature is even higher, can be driven to cause the second cooling fluid L2 or the first cooling fluid L1 to flow in the direction from the second inlet 13 to the second outlet 14, or from the first inlet 11 to the first outlet 12.

[0064] In other words, when the first circulator 50a is driven, the second circulator 50b adjacent to it can be driven in the direction in which the cooling fluids L1 and L2 flow, that is, when the cooling fluids L1 and L2 in a space with a relatively lower temperature flow into a space with a higher temperature.

[0065] For example, as shown in Figure 5, the first cooling fluid L1 is impregnated into the first space 10a at the bottom of the support portion 40, and the second cooling fluid L2 is impregnated into the second space 10b at the top of the support portion 40.

[0066] If, at the point where the first circulator 50a is connected, the temperature of the first cooling fluid L1 in the first space 10a is higher than the temperature of the second cooling fluid L2 in the second space 10b, and the temperature difference exceeds a threshold, the first circulator 50a can be driven.

[0067] The first circulator 50a causes the second cooling fluid L2 from the second space 10b, which is at a relatively lower temperature, to flow into the first space 10a, which is at an even higher temperature. In this way, the second cooling fluid L2 flows into the first space 10a and mixes with the first cooling fluid L1, thereby lowering the overall temperature of the cooling fluids L1 and L2.

[0068] In this case, the second circulator 50b adjacent to the first circulator 50a can be driven in the direction of flow of the first cooling fluid L1 in the first space 10a, which has a relatively higher temperature, i.e., from the first inlet 11 to the first outlet 12. The second circulator 50b can improve the cooling efficiency by circulating the cooling fluids L1 and L2 in the opposite direction to the first circulator 50a, from the first space 10a to the second space 10b, thereby inducing overall circulation of the cooling fluids L1 and L2.

[0069] Furthermore, as shown in Figure 6, if the temperature of the first cooling fluid L1 in the first space 10a is lower than the temperature of the second cooling fluid L2 in the second space 10b at the point where the first circulator 50a is connected, and the temperature difference exceeds a threshold, the first circulator 50a can be driven.

[0070] The first circulator 50a causes the first cooling fluid L1 from the first space 10a, which is at a relatively lower temperature, to flow into the second space 10b, which is at an even higher temperature. In this way, the first cooling fluid L1 flows into the second space 10b and mixes with the second cooling fluid L2, thereby lowering the overall temperature of the cooling fluids L1 and L2.

[0071] In this case, the second circulator 50b adjacent to the first circulator 50a can be driven in the direction of flow of the second cooling fluid L2 in the second space 10b, which has a relatively higher temperature, i.e., from the second inlet 13 to the second outlet 14. The second circulator 50b can improve the cooling efficiency by circulating the cooling fluids L1 and L2 from the second space 10b to the first space 10a, in the opposite direction to the first circulator 50a, thereby inducing overall circulation of the cooling fluids L1 and L2.

If the temperature difference between the first space and the second space exceeds a predetermined threshold, the first circulator at the location where the temperature difference was measured is driven to move the first or second cooling fluid from the first or second space, which has a lower temperature, to the second or first space, which has a higher temperature. A method for controlling an immersion cooling module according to claim 6, further comprising the step of selecting the location where the temperature difference is largest if the temperature difference between the first space and the second space exceeds a predetermined threshold, and there are multiple locations where the temperature difference has been measured.

8. The step of determining whether the temperature difference between the first space and the second space exceeds a predetermined threshold is: A method for controlling an immersion cooling module according to claim 6, further comprising the step of measuring in real time the temperature of the first cooling fluid on the first space side and the temperature of the second cooling fluid on the second space side at a plurality of locations where a circulator connecting the first space side and the second space side is coupled, and measuring the difference between them.
