[0048] The standardization of energy storage container sizes is crucial for the transportation and use of energy storage containers. Standardized energy storage container sizes make it easier to transport energy storage containers internationally. However, under a specific size, how to increase the energy density of energy storage containers has become one of the technical issues that need to be solved urgently.

[0049] In the related art, due to the arrangement of pipes in the liquid cooling system in the energy storage container, the liquid cooling system occupies too much space in the energy storage container, which makes the battery pack occupy less space in the energy storage container, thereby affecting the energy density of the energy storage container.

[0050] In view of this, the utility model proposes a liquid cooling system. Figures 1 to 8 Some embodiments of the present invention are shown below. Figures 1 to 8 As shown in the direction marking, the X direction is the first direction, the Z direction is the second direction, and the Y direction is the third direction. The first direction, the second direction, and the third direction intersect each other in pairs, and the angles between the first direction, the second direction, and the third direction are not limited, and can be 80°, 85°, 90°, 95°, or 100°; preferably, in the following embodiments, the angles between the first direction, the second direction, and the third direction are 90° for explanation, that is, a spatial rectangular coordinate system is established by the first direction, the second direction, and the third direction to explain some embodiments of the present application; it should be emphasized that the angle between the first direction, the second direction, and the third direction is 90°, which does not constitute a limitation on the following embodiments of the present application.

[0051] See also Figure 1 to Figure 2The liquid cooling system 1000 includes a liquid cooling component 1, and the liquid cooling component 1 includes a plurality of liquid cooling plate groups 11, and the plurality of liquid cooling plate groups 11 are arranged at intervals along a first direction X, and each of the liquid cooling plate groups 11 includes a plurality of liquid cooling plates 111 arranged at intervals along a second direction Z, and a liquid cooling cavity 1A is formed in each of the liquid cooling plates 111; wherein, a plurality of battery modules may be mounted on the liquid cooling plate 111, and one of the liquid cooling plates 111 may dissipate heat for the plurality of battery modules, that is, one of the liquid cooling plates 111 and the plurality of battery modules mounted on the liquid cooling plate 111 may constitute a part of a battery pack.

[0052] There is no limit to the number of the liquid cooling components 1, which may be one or more. In a specific embodiment of the present application, two liquid cooling components 1 are provided, and the two liquid cooling components 1 are arranged in the third direction Y. In the following embodiments, the liquid cooling system 1000 is explained as including one liquid cooling component 1.

[0053] In some embodiments of the present application, the liquid cooling system 1000 further includes a cooling tube group 2, the cooling tube group 2 includes a plurality of liquid inlet pipelines 21 and liquid outlet pipelines 22 extending along the second direction Z, and the plurality of liquid inlet pipelines 21 and the plurality of liquid outlet pipelines 22 are alternately arranged in the first direction X; each of the liquid cooling plate groups 11 is located between any adjacent liquid inlet pipelines 21 and the liquid outlet pipelines 22; wherein the plurality of liquid cooling plates 111 in each of the liquid cooling plate groups 11 are respectively connected to the liquid inlet pipeline 21 and the liquid outlet pipeline 22. The pipeline 22 is connected; the liquid inlet pipeline 21 and the liquid outlet pipeline 22 extend along the second direction Z, so that the liquid inlet pipeline 21 and the liquid outlet pipeline 22 will not occupy too much space between two adjacent liquid cooling plate groups 11 in the first direction X, thereby making the distance between the two adjacent liquid cooling plate groups 11 closer; on the basis of the fixed length of the energy storage container in the first direction X, more space can be reserved in the energy storage container for stacking battery packs, thereby improving the energy density per unit volume of the energy storage container.

[0054] In the technical solution of the present utility model, the liquid inlet pipeline 21 and the liquid outlet pipeline 22 are provided on opposite sides of one of the liquid cooling plate groups 11 to complete the circulation of the cooling liquid in the liquid cooling plate group 11 . The liquid inlet pipeline 21 located between two adjacent liquid-cooling plate groups 11 can be connected to the liquid-cooling cavities 1A of multiple liquid-cooling plates 111 in the two adjacent liquid-cooling plate groups 11, and the liquid outlet pipeline 22 located between the two adjacent liquid-cooling plate groups 11 can also be connected to the liquid-cooling cavities 1A of multiple liquid-cooling plates 111 in the two adjacent liquid-cooling plate groups 11; that is, only one pipeline is provided between the two adjacent liquid-cooling plate groups 11 to realize the inflow or outflow of coolant in the two liquid-cooling plate groups 11. Compared with the related art that two pipelines are required to be provided on the opposite sides of each liquid-cooling plate group 11 to realize the input or output of coolant, the technical solution of the present application can effectively reduce the number of pipelines of the cooling tube group 2, thereby reducing the space occupied by the cooling tube group 2 in the energy storage container, thereby providing more space in the energy storage container for placing battery packs, so as to improve the energy density of the energy storage container.

[0055] It can be understood that each of the liquid cooling plates 111 also includes a liquid inlet 1B and a liquid outlet 1C connected to the liquid cooling cavity 1A; the liquid inlet pipeline 21 connected to the liquid inlet 1B of the liquid cooling plate 111 can input cooling liquid into the liquid cooling cavity 1A in the liquid cooling plate 111, and the liquid outlet pipeline 22 connected to the liquid outlet 1C of the liquid cooling plate 111 can receive cooling liquid flowing out of the liquid cooling cavity 1A in the liquid cooling plate 111.

[0056] Taking the liquid cooling plate group 11 and the adjacent liquid inlet pipeline 21 and the liquid outlet pipeline 22 as an example, the opening positions of the liquid inlet 1B and the liquid outlet 1C of the liquid cooling plate 111 in the liquid cooling plate group 11 are not restricted; in one embodiment of the present application, the liquid inlet 1B of the liquid cooling plate 111 is arranged close to the liquid inlet pipeline 21, and the liquid outlet 1C of the liquid cooling plate 111 is arranged close to the liquid outlet pipeline 22; in another embodiment of the present application, the liquid outlet 1C of the liquid cooling plate 111 is arranged close to the liquid inlet pipeline 21, and the liquid inlet 1B of the liquid cooling plate 111 is arranged close to the liquid outlet pipeline 22.

[0057] See also Figure 2 In a specific embodiment of the present application, in the first direction, the liquid inlet pipeline 21 is arranged close to the liquid inlet 1B of the liquid cooling plate 111, and the liquid outlet 1C of the liquid cooling plate 111 is arranged close to the liquid outlet pipeline 22. That is, such an arrangement can shorten the length of the pipeline connecting the liquid inlet pipeline 21 and the liquid inlet 1B of the liquid cooling plate 111 and the length of the pipeline connecting the liquid outlet pipeline 22 and the liquid outlet 1C of the liquid cooling plate 111.

[0058] See also Figure 3 to Figure 4 In some embodiments of the present application, the liquid cooling system 1000 further includes a plurality of first pipelines 3, each of the first pipelines 3 connecting the liquid inlet pipeline 21 with the liquid inlet 1B of the liquid cooling plate 111 or connecting the liquid outlet pipeline 22 with the liquid outlet 1C of the liquid cooling plate 111.

[0059] Further, the first pipeline 3 includes a first pipe section 31, a second pipe section 32 and a connecting piece 33, the first pipe section 31 is connected to the liquid inlet 1B or the liquid outlet 1C of the liquid cooling plate 111; the second pipe section 32 is connected to the liquid inlet pipeline 21 or the liquid outlet pipeline 22; the connecting piece 33 connects the first pipe section 31 and the second pipe section 32, and the connecting piece 33 has a first working state and a second working state; wherein, when the connecting piece 33 is in the first working state, the first pipe section 31 is connected to the second pipe section 32, and when the connecting piece 33 is in the second working state, the first pipe section 31 is not connected to the second pipe section 32.

[0060] That is, in the above embodiment, the connector 33 can control the on-off of the first pipeline 3. When the liquid cooling plate 111 or the battery pack needs to be maintained, disassembled or replaced, the connector 33 is controlled to be in the second working state, that is, the coolant in the liquid inlet pipeline 21 will not flow into the liquid cooling cavity 1A of the liquid cooling plate 111 along the first pipeline 3, and the coolant in the liquid cooling cavity 1A of the liquid cooling plate 111 will not flow out along the first pipeline 3 to the liquid outlet pipeline 22. In this way, when the liquid cooling plate 111 or the battery pack is maintained, disassembled or replaced, the coolant can be prevented from flowing out of the liquid inlet pipeline 21 or the liquid outlet pipeline 22, thereby avoiding waste of coolant.

[0061] In addition, the second pipe segment 32 is extended along the third direction Y, that is, the orthographic projection of the second pipe segment 32 in the third direction Y is located on the liquid inlet pipeline 21 or the liquid outlet pipeline 22, thereby not increasing the gap between the two adjacent liquid cooling plate groups 11.

[0062] In some embodiments of the present application, the connecting member 33 includes a first connecting portion 33A and a second connecting portion 33B, the first connecting portion 33A is connected to the first pipe segment 31; the second connecting portion 33B is connected to the second pipe segment 32, and the second connecting portion 33B is detachably connected to the first connecting portion 33A; that is, in this embodiment, the connection or disconnection of the first pipeline 3 is controlled by connecting or separating the first connecting portion 33A and the second connecting portion 33B.

[0063] Further, when the connecting member 33 is in the first working state, the first connecting portion 33A and the second connecting portion 33B are connected and communicated with each other, the first connecting portion 33A is communicated with the first pipe segment 31, and the second connecting portion 33B is communicated with the second pipe segment 32; when the connecting member 33 is in the second working state, the first connecting portion 33A and the second connecting portion 33B are separated from each other, the first connecting portion 33A closes one end of the first pipe segment 31, and the second connecting portion 33B closes one end of the second pipe segment 32. In this embodiment, such an arrangement ensures that when the liquid cooling plate 111 is disassembled, the coolant in the liquid cooling chamber 1A in the liquid cooling plate 111 will not flow out from the first pipe section 31, and the coolant in the liquid inlet pipeline 21 and the liquid outlet pipeline 22 will also not flow out from the second pipe section 32, thereby avoiding waste of coolant; and the detachable connection of the connecting piece 33 can facilitate the operator to disconnect the pipeline connection between the liquid cooling plate 111 and the liquid inlet pipeline 21 or the liquid outlet pipeline 22, thereby facilitating the disassembly and connection of the liquid cooling plate 111.

[0064] In a specific embodiment of the present application, the connector 33 is a two-way stop valve 330. Since the cost of the two-way stop valve 330 is relatively high, the two-way stop valve 330 is provided on part of the first pipeline 3 to control the cost of the liquid cooling system 1000.

[0065] Please refer again Figure 1 and Figure 2 The liquid cooling system 1000 further includes a second pipeline 4, a third pipeline 5, and a liquid cooling unit 6. The second pipeline 4 is connected to the plurality of liquid inlet pipelines 21; the third pipeline 5 is connected to the plurality of liquid outlet pipelines 22; and the liquid cooling unit 6 is connected to both the second pipeline 4 and the third pipeline 5. The liquid cooling unit 6 can transport the cooling liquid from the second pipeline 4 to the plurality of liquid inlet pipelines 21, and recover the cooling liquid output from the plurality of liquid outlet pipelines 22 through the third pipeline 5.

[0066] See also Figures 5 and 6 The liquid cooling system 1000 also includes a plurality of switch components 7, which are respectively arranged on the liquid inlet pipeline 21 and the liquid outlet pipeline 22; the switch components 7 include a third working state and a fourth working state; wherein, when the switch component 7 is in the third working state, the second pipeline 4 is connected to the liquid inlet pipeline 21 or the third pipeline 5 is connected to the liquid outlet pipeline 22, and when the switch component 7 is in the fourth working state, the second pipeline 4 is not connected to the liquid inlet pipeline 21 or the third pipeline 5 is not connected to the liquid outlet pipeline 22.

[0067] That is, in the above embodiment, a liquid cooling plate group 11 is used for illustration, and the liquid cooling plate group 11 is respectively provided with a liquid inlet pipeline 21 and a liquid outlet pipeline 22 on two opposite sides in the first direction X. When it is necessary to dismantle or install a plurality of the liquid cooling plates 111 of the liquid cooling plate group 11, the switch element 7 on the liquid inlet pipeline 21 and the liquid outlet pipeline 22 is controlled to be in the fourth working state, thereby limiting the coolant from entering the liquid inlet pipeline 21 and limiting the coolant from flowing back to the liquid outlet pipeline 22, and thus when dismantling or installing a plurality of the liquid cooling plates 111 of the liquid cooling plate group 11, the waste of coolant in the liquid cooling system 1000 can be effectively avoided.

[0068] When the switch element 7 is in the third working state, the liquid inlet pipeline 21 is normally connected to the second pipeline 4 , and the liquid outlet pipeline 22 is normally connected to the third pipeline 5 .

[0069] In a specific embodiment of the present application, the switch member 7 is a switch valve, which, in addition to having the third working state and the fourth working state, can also adjust the flow in the liquid inlet pipeline 21 or the liquid outlet pipeline 22; see Figure 1 and Figure 2 The number of the first pipelines 3 connected to the liquid outlet pipelines 22 located on the opposite sides of the liquid cooling system 1000 in the first direction X is half the number of the first pipelines 3 connected to the liquid inlet pipeline 21 or the liquid outlet pipeline 22 located between two adjacent liquid cooling plate groups 11. Therefore, the flow rates of the multiple liquid inlet pipelines 21 and the liquid outlet pipelines 22 in the liquid cooling system 1000 can be controlled by adjusting the switch valve to ensure the consistency of flow distribution in the liquid cooling system 1000.

[0070] Further, a drain valve 8 is provided on at least one of the liquid inlet pipeline 21 or the liquid outlet pipeline 22. That is, on the basis of the above embodiment, when the switch members 7 located on the liquid inlet pipeline 21 and the liquid outlet pipeline 22 are both in the fourth working state, since the liquid inlet pipeline 21 and the liquid outlet pipeline 22 are connected to each other through the liquid cooling cavity 1A of the liquid cooling plate 111, the coolant in the liquid inlet pipeline 21, the liquid outlet pipeline 22 and the liquid cooling plate 111 can be completely drained through the drain valve 8, so as to further avoid the waste of coolant when the liquid cooling plate 111 is disassembled.

[0071] It can be understood that the drain valve 8 can be arranged on the liquid inlet pipeline 21, the liquid outlet pipeline 22, or both. For explanation, taking the second direction Z as the up-down direction, in some embodiments of the present application, the drain valve 8 is arranged at a position close to the bottom of the liquid inlet pipeline 21 and / or the liquid outlet pipeline 22, so that the coolant can be discharged under the action of gravity, thereby ensuring that the coolant in the liquid inlet pipeline 21, the liquid outlet pipeline 22 and the liquid cooling cavity 1A of the liquid cooling plate 111 in the above embodiment is completely drained; please refer to Figure 7 In a specific embodiment of the present application, the drain valve 8 is arranged on the liquid outlet pipeline 22.

[0072] In some embodiments of the present application, the second pipeline 4 and the third pipeline 5 are arranged on opposite sides of the plurality of liquid cooling plate groups 11 in the second direction Z; the second pipeline 4 is connected to the same end of the plurality of liquid inlet pipelines 21; the third pipeline 5 is connected to the same end of the plurality of liquid outlet pipelines 22. That is, in this embodiment, such an arrangement allows the pipelines in the liquid cooling system 1000 to be neatly arranged, and at the same time, the extension lengths of the second pipeline 4 and the third pipeline 5 can be effectively shortened, that is, the second pipeline 4 only needs to extend to the same end of the corresponding plurality of liquid inlet pipelines 21, and the third pipeline 5 only needs to extend to the same end of the corresponding plurality of liquid outlet pipelines 22.

[0073] In addition, since the pipeline of the liquid cooling system 1000 needs to discharge the gas in the pipeline when the coolant is passed through, in some embodiments of the present application, an exhaust valve 9 is also provided on the liquid inlet pipeline 21 and / or the liquid outlet pipeline 22, that is, the gas in the pipeline of the liquid cooling system 1000 can be discharged through the exhaust valve 9. Figure 8 In a specific embodiment of the present application, the exhaust valve 9 is arranged on the liquid inlet pipeline 21 and is arranged close to the top of the liquid inlet pipeline 21; since the air will move upward in the liquid inlet pipeline 21, the exhaust valve 9 located above the liquid inlet pipeline 21 can lead out the air in the pipeline of the liquid cooling system 1000.

[0074] The utility model further proposes an energy storage container, which includes a liquid cooling system 1000. The liquid cooling system 1000 is as described above. Since the energy storage container adopts all the technical solutions of all the above embodiments, it at least has the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.
