[0058] Hereinafter, an embodiment of the present disclosure will be described in detail with reference to the accompanying drawings.

[0059] Figure 1 This is a cross-sectional schematic diagram of a liquid immersion cooling module according to an embodiment of the present disclosure. Figure 2 yes Figure 1 An enlarged view of part A. Figure 3 This is a schematic diagram of the construction of a looper 50 according to an embodiment of the present disclosure.

[0060] According to one embodiment of the present disclosure, a liquid immersion cooling module may include: a receiving portion 10 containing cooling fluids L1 and L2 to immerse a battery cell 20; a support portion 40 dividing the receiving portion 10 into a first space 10a on one side containing the first cooling fluid L1 and a second space 10b on the other side containing the second cooling fluid L2, and being coupled to at least one of the battery cells 20; and a circulator 50 coupled to the support portion 40 in a manner that the first space 10a and the second space 10b communicate with each other, and being coupled to and driven by the support portion 40 to allow the first cooling fluid L1 and the second cooling fluid L2 to flow to each other.

[0061] like Figure 1 As shown, the receiving portion 10 forms a space to receive cooling fluids L1 and L2 to immerse the battery cell 20. Here, the battery cell 20 is used as an example of an object immersed in the cooling fluids L1 and L2, but considering the size or specifications of this liquid immersion cooling module, it can of course also be applied to data centers, etc., including large devices or systems, instead of the battery cell 20.

[0062] like Figure 1 As shown, the support portion 40 can be integrated into the interior of the receiving portion 10 in a way that divides the upper and lower spaces of the receiving portion 10. The integration form or shape of the support portion 40 is not limited to that shown in the figure, and it can be appropriately configured to allow the flow of cooling fluids L1 and L2 to occur in the two spaces.

[0063] In one embodiment of this disclosure, the support portion 40 is described as being combined to form a first space 10a, which serves as the lower space of the support portion 40, and a second space 10b, which serves as the upper space of the support portion 40. The first space 10a and the second space 10b are physically separated spaces, and each space can be supplied with cooling fluids L1 and L2, that is, the first cooling fluid L1 and the second cooling fluid L2 flow independently.

[0064] That is, such as Figure 1 As shown, a first inflow portion 11 into which the first cooling fluid L1 flows in at one end and a first outflow portion 12 into which the first cooling fluid L1 flows out at the other end are respectively formed on one side and the other side of the first space 10a, thereby forming the flow direction of the cooling fluids L1 and L2.

[0065] Furthermore, the second space 10b may have an inflow portion and an outflow portion formed on opposite sides of the first space 10a. That is, a second inflow portion 13 may be formed on the second space 10b on the side opposite to the first inflow portion 11 of the first space 10a, allowing the second cooling fluid L2 to flow in, and a second outflow portion 14 may be formed on the second space 10b on the side opposite to the first outflow portion 12 of the first space 10a, allowing the second cooling fluid L2 to flow out.

[0066] The first cooling fluid L1 and the second cooling fluid L2 can be different types of cooling fluids L1 and L2, or they can be the same type of cooling fluid L1 and L2.

[0067] When different cooling fluids L1 and L2 are used, the configuration of the physical spaces of the first space 10a and the second space 10b, the mixing probability between the fluids required for the smooth mixing flow of the first cooling fluid L1 and the second cooling fluid L2, or the difference in their specific gravity can be appropriately selected and applied.

[0068] The cooling fluids L1 and L2 can be non-conductive fluids to prevent energization of the submerged electronic products, battery cells 20, servers, etc. For example, the cooling fluids L1 and L2 can contain base oil. The base oil can contain mineral oil, or it can contain polyalphaolefin (PAO) and / or ester base oil. However, the cooling fluids L1 and L2 disclosed herein are not limited to these; any fluid capable of cooling the battery cell is acceptable.

[0069] The support portion 40 can be configured to divide the space inside the receiving portion 10 into a first space 10a and a second space 10b and be combined with the battery cell 20. Although an example of the battery cell 20 being combined with the support portion 40 is shown in this disclosure, it can also be physically fixed to the support portion 40 in the case of other devices such as coolable electronic devices or servers, so as to effectively immerse and cool them inside the receiving portion 10.

[0070] The battery cell 20, which is the object of cooling, is combined with the support part 40 and disposed at each fixed position. Therefore, 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 of the cooling fluids L1 and L2 at each point, or the battery cell 20 disposed at each point can be effectively cooled by guiding the mixed flow of the cooling fluids L1 and L2.

[0071] A porous moisture-absorbing component 30 can be attached to the joint surface where the battery cell 20 and the support portion 40 meet. By attaching the porous moisture-absorbing component 30, a buffering effect can be provided at the joint between the support portion 40 and the battery cell 20, thereby appropriately coping with the expansion or physical deformation of the battery cell 20. Furthermore, the cooling fluids L1 and L2 naturally absorb moisture from the porous moisture-absorbing component 30 to cool the outer peripheral surface of the battery cell 20, and the latent heat generated by the vaporization of the cooling fluids L1 and L2 due to the heat generated by the battery cell 20 can further cool the battery cell 20.

[0072] The circulator 50 can be driven at at least one point on the support 40 to cause the first cooling fluid L1 and the second cooling fluid L2 in the first space 10a and the second space 10b divided by the support 40 to mix and flow with each other.

[0073] like Figure 2 As shown, the circulator 50 may include a first propeller 53 immersed in a first cooling fluid L1 in a first space 10a and a second propeller 54 immersed in a second cooling fluid L2 in a second space 10b.

[0074] The first propeller 53 and the second propeller 54 are connected to the rotating shaft 51a, which is driven to rotate by the drive device 51. Therefore, the flow direction of the first cooling fluid L1 and the second cooling fluid L2 can be determined according to the rotation direction.

[0075] Specifically, such as Figure 3 As shown, the circulator 50 may include: a first propeller 53 formed in the region of the first space 10a; a second propeller 54 formed in the region of the second space 10b; a rotating shaft 51a, which is coupled with the first propeller 53 and the second propeller 54; and a support plate 52, which is coupled with the drive device 51 to enable the rotating shaft 51a to rotate, and the drive device 51 is coupled to the support portion 40, and has at least one through hole 52a that connects the first space 10a and the second space 10b.

[0076] That is, the support plate 52 is combined with the support portion 40 and located at the boundary between the first space 10a and the second space 10b, and the drive device 51 can be combined with the support plate 52. The drive device 51 may include, for example, a motor drive device, or various rotary drive devices may be used to rotate the rotating shaft 51a.

[0077] The support plate 52 is combined with the drive device 51, and the drive device 51 can be combined to form a rotating shaft 51a that can rotate, so that the first propeller 53 and the second propeller 54 can rotate.

[0078] The first propeller 53 and the second propeller 54 are driven simultaneously in the direction of rotation of the rotation axis 51a, which can cause the first cooling fluid L1 to flow from the first space 10a to the second space 10b, or cause the second cooling fluid L2 to flow from the second space 10b to the first space 10a in the opposite direction.

[0079] Since the direction of movement of the cooling fluid is the same as the direction of rotation of the first propeller 53 and the second propeller 54, the flow of the cooling fluids L1 and L2 can be controlled by adjusting the direction of rotation of a rotating shaft 51a.

[0080] like Figure 3 As shown, the support plate 52 may have at least one through hole 52a that connects the first space 10a and the second space 10b when the first propeller 53 and the second propeller 54 drive the cooling fluids L1 and L2 to flow. The amount or speed of the cooling fluids L1 and L2 flowing in per unit time can be adjusted according to the shape or size of the through hole 52a to maximize the cooling efficiency.

[0081] The through holes 52a of the support plate 52 can be spaced apart to form multiple circular through holes 52a along the circumference of the support plate 52. Of course, through holes 52a of different shapes can also be formed by changing their diameter. In addition, the appropriate size and number of through holes 52a can be determined according to the configuration position of the circulator 50, that is, according to the temperature of the cooling fluids L1 and L2 flowing based on the first cooling fluid L1 and the second cooling fluid L2, or according to the heat generation of the battery cells 20 connected to each point of the support portion 40, in order to improve cooling efficiency.

[0082] By adjusting the area of ​​the through-hole 52a through which cooling fluids L1 and L2 flow to and from the first space 10a and the second space 10b, the flow rate of cooling fluids L1 and L2 through the support plate 52 per unit time can be adjusted, and by adjusting the total area of ​​the through-hole 52a, the total amount of cooling fluids L1 and L2 passing through per unit time can be adjusted.

[0083] Figure 4 This is a flowchart of a control method for a liquid immersion cooling module according to an embodiment of the present disclosure. Figure 5 This is a first flowchart of a control method for a liquid immersion cooling module according to an embodiment of the present disclosure. Figure 6 This is a second flowchart of a control method for a liquid immersion cooling module according to an embodiment of the present disclosure.

[0084] A control method for a liquid immersion cooling module according to an embodiment of the present disclosure may include: measuring the temperature of the first space 10a side and 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 preset threshold; and when the temperature difference between the first space 10a side and the second space 10b side exceeds the preset threshold, driving the first circulator 50a at the point where the temperature difference is measured, so that the first space 10a side or the second space 10b side with a lower temperature... The steps include: the first cooling fluid L1 or the second cooling fluid L2 on the 0b side flowing towards the second space 10b side or the first space 10a side with a higher temperature; and the second circulator 50b adjacent to the direction in which the second cooling fluid L2 or the first cooling fluid L1 flows from the second inlet 13 to the second outlet 14 or from the first inlet 11 to the first outlet 12 along the direction in which the second cooling fluid L2 or the first cooling fluid L1 flows from the second space 10b side or the first space 10a side with a higher temperature to the first space 10a side or the second space 10b side with a lower temperature.

[0085] like Figure 5As shown, the first step is to measure the temperature of the first space 10a side and the second space 10b side 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 using the first temperature sensor T1 and the second temperature sensor T2 respectively.

[0086] 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. At the inflow section, the temperature of the cooling fluids L1 and L2 is the lowest. As they move along the flow direction, the temperature of the cooling fluids L1 and L2 gradually increases during the cooling of the battery cell 20, which is the object of cooling, thereby reducing the cooling efficiency.

[0087] 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, the cooling efficiency of the battery cell 20 submerged in the housing 10 can be maximized.

[0088] 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 in a manner that connects the first space 10a and the second space 10b, the heating state or cooling efficiency state of the battery cell 20 can be effectively monitored. Furthermore, since the temperature difference at the location where the circulator 50 is positioned can be measured, this should be taken into account when configuring the circulator 50 to ensure it is installed and connected at an appropriate location and spacing.

[0089] The next step is to determine whether the temperature difference measurement value of the first space 10a side and the second space 10b side exceeds the preset threshold.

[0090] The temperatures of the first cooling fluid L1 according to its flow direction and the second cooling fluid L2 according to its flow direction can be formed within a predetermined range. Therefore, when the temperature difference between the first cooling fluid L1 and the second cooling fluid L2 at each location exceeds a threshold, it indicates a sharp increase in heat generation at the cell 20 as a whole or at a specific location. Since the cell 20 spans the first space 10a side and the second space 10b side, a sharp increase in 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 may occur due to heat generation issues near the interface.

[0091] The threshold for the temperature difference between the first space 10a side and the second space 10b side can, of course, be set to different values ​​at various points in the direction of cooling fluid flow.

[0092] If the temperature difference between the first space 10a side and the second space 10b side exceeds a preset threshold, the first circulator 50a at the point where the temperature difference exceeds the threshold can operate.

[0093] That is, the first circulator 50a at the point where the temperature difference is measured can be driven to flow the first cooling fluid L1 or the second cooling fluid L2 from the side of the first space 10a or the second space 10b, which has a lower temperature, to the side of the second space 10b or the first space 10a, which has a higher temperature.

[0094] By directing the cooling fluids L1 and L2 from the lower-temperature side of the space to the relatively higher-temperature side, the temperature difference between the first space 10a and the second space 10b can be mitigated to the maximum extent to maintain cooling balance, and the heat generation at specific points can be effectively addressed.

[0095] Next, the second circulator 50b adjacent to the second circulator 50b can drive the second cooling fluid L2 or the first cooling fluid L1 to flow from the second inlet 13 to the second outlet 14 or from the first inlet 11 to the first outlet 12 in the direction where the second cooling fluid L2 or the first cooling fluid L1 flows from the side of the second space 10b or the first space 10a, which is at a higher temperature, to the side of the first space 10a or the second space 10b, which is at a relatively lower temperature.

[0096] That is, when the first circulator 50a is driven, a second circulator 50b can be driven in the direction of the flow of cooling fluids L1 and L2, i.e., when the cooling fluids L1 and L2 in the space with a relatively lower temperature flow into the space with a higher temperature, and the space into which the cooling fluids L1 and L2 flow.

[0097] For example, such as Figure 5 As shown, the first space 10a at the lower part of the support 40 is not immersed in the first cooling fluid L1, and the second space 10b at the upper part of the support 40 is not immersed in the second cooling fluid L2.

[0098] Initially, when the temperature of the first cooling fluid L1 in the first space 10a at the point where the first circulator 50a is connected 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 activated.

[0099] The first circulator 50a draws a second cooling fluid L2, which has a relatively lower temperature, into the first space 10a, which has a higher temperature. The second cooling fluid L2 can then mix with the first cooling fluid L1 after flowing into the first space 10a to reduce the overall temperature of the cooling fluids L1 and L2.

[0100] In this case, a second circulator 50b adjacent to the first circulator 50a can be driven along the direction in which the first cooling fluid L1 flows 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 guide the circulation of the overall cooling fluids L1 and L2 to improve cooling efficiency by circulating the cooling fluids L1 and L2 in the opposite direction to the first circulator 50a, i.e., from the first space 10a to the second space 10b.

[0101] In addition, such as Figure 6 As shown, at the point where the first circulator 50a is connected, when 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 and the temperature difference exceeds a threshold, the first circulator 50a can be activated.

[0102] The first circulator 50a draws the first cooling fluid L1, which has a relatively lower temperature, into the second space 10b, which has a higher temperature. The first cooling fluid L1 can then mix with the second cooling fluid L2 after flowing into the second space 10b to reduce the overall temperature of the cooling fluids L1 and L2.

[0103] In this case, the second circulator 50b, adjacent to the first circulator 50a, can be driven along the direction of the flow of the second cooling fluid L2 in the relatively higher second space 10b, i.e., from the second inlet 13 to the second outlet 14. The second circulator 50b can guide the circulation of the overall cooling fluids L1 and L2 to improve cooling efficiency by circulating the cooling fluids L1 and L2 in the opposite direction to the first circulator 50a, i.e., from the second space 10b to the first space 10a.

These implementation examples are used to specifically illustrate the present disclosure, which is merely illustrative and not intended to limit the scope of the appended claims.
