Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application. In addition, it should be understood that the specific implementation manners described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, unless otherwise stated, the orientation words such as "upper" and "lower" usually refer to the upper and lower in the actual use or working state of the device, specifically the drawing direction in the accompanying drawings; and "inner" and "outer" refer to the outline of the device.

[0034] An embodiment of the present application provides a flow regulator, a liquid cooling component and an energy storage system.

[0035] Figure 1 Schematic structural diagram of an embodiment of the liquid cooling component provided by an embodiment of the present application. As Figure 1As shown, the liquid cooling component 100 includes a pipeline structure 110 and a plurality of liquid cooling plates 121. A cooling flow channel (not shown in the figure) is provided inside the liquid cooling plate 121. The pipeline structure 110 is communicated with the cooling flow channels of the plurality of liquid cooling plates 121, so as to supply coolant to the cooling flow channels of the plurality of liquid cooling plates 121 through the pipeline structure 110. The liquid cooling plate 121 is used to connect with a battery module (not shown in the figure) of the energy storage system to cool the battery module.

[0036] Among them, the energy storage system can include a plurality of battery modules, and the plurality of battery modules are connected to the plurality of liquid cooling plates 121 in a one-to-one correspondence, so that each liquid cooling plate 121 cools the corresponding battery module. Specifically, as Figure 1 shown, the plurality of liquid cooling plates 121 are divided into a plurality of liquid cooling plate groups 120. Each liquid cooling plate group 120 includes a plurality of liquid cooling plates 121 arranged at intervals along the height direction of the energy storage system. A battery module is arranged on each liquid cooling plate 121.

[0037] Continue to refer to Figure 1 , the pipeline structure 110 can include a main pipeline 111 and a plurality of branch pipelines 112. The plurality of branch pipelines 112 are respectively communicated with the main pipeline 111 and are sequentially distributed along the length direction of the main pipeline 111. Each branch pipeline 112 is respectively communicated with the cooling flow channel of at least one liquid cooling plate 121. Thus, the coolant can flow between the cooling flow channel of the liquid cooling plate 121 and the main pipeline 111 through the branch pipeline 112. Among them, the main pipeline 111 can be an inlet pipe, and the coolant in the main pipeline 111 is branched into the cooling flow channels of different liquid cooling plates 121 through the plurality of branch pipelines 112. Or, the main pipeline 111 can also be an outlet pipe, and the coolant in the cooling flow channel of the liquid cooling plate 121 flows into the main pipeline 111 through the branch pipeline.

[0038] Specifically, the pipeline structure 110 can include a plurality of main pipelines 111, and each main pipeline 111 is respectively communicated with a plurality of branch pipelines 112. The inlets of the cooling flow channels of the plurality of liquid cooling plates 121 in the liquid cooling plate group 120 are respectively communicated with a main pipeline 111 through the branch pipelines 112, so that the coolant in the main pipeline 111 is branched into the cooling flow channels of the plurality of liquid cooling plates 121 in the liquid cooling plate group 120 through the plurality of branch pipelines 112. The outlets of the cooling flow channels of the plurality of liquid cooling plates 121 in the liquid cooling plate group 120 are respectively communicated with another main pipeline 111 through other branch pipelines 112, so that the coolant in the cooling flow channels of the plurality of liquid cooling plates 121 in the liquid cooling plate group 120 converges into another main pipeline 111 through other branch pipelines 112, so as to realize the cyclic supply of coolant to the liquid cooling plate 121 through the pipeline structure 110.

[0039] Among them, the main pipeline 111 is along the height direction of the energy storage system, and the plurality of branch pipelines 112 are sequentially distributed along the length direction of the corresponding main pipeline 111.

[0040] For the battery modules at different positions in the energy storage system, there are also differences in their temperatures. In order to enable the liquid cooling component 100 to have a good cooling effect on each battery module, it is necessary to adjust the flow rate of the coolant flowing into different liquid cooling plates 121 in the pipeline structure 110, so as to adjust the cooling effects of different liquid cooling plates 121.

[0041] For example: more coolant in the pipeline structure 110 can be diverted into the liquid cooling plate 121 corresponding to the battery module with a higher temperature, while less coolant in the pipeline structure 110 is diverted into the liquid cooling plate 121 corresponding to the battery module with a relatively lower temperature, so that the cooling effect of the liquid cooling plate 121 corresponding to the battery module with a relatively higher temperature is better, while reducing the cooling effect of the liquid cooling plate 121 corresponding to the battery module with a relatively lower temperature, realizing precise control of the cooling effect of each battery module, which is beneficial to reducing the temperature difference between multiple battery modules and improving the overall performance of the energy storage system.

[0042] In addition, there are differences in the pressure of the coolant at different positions in the pipeline structure 110, resulting in differences in the flow rate of the coolant diverted from different positions of the pipeline structure 110 into the liquid cooling plate 121. Therefore, it is also necessary to adjust the flow rate of the coolant flowing into different liquid cooling plates 121 in the pipeline structure 110, so that the flow rate of the coolant in the cooling flow channel of the liquid cooling plate 121 is adapted to the cooling effect that the liquid cooling plate 121 needs to achieve.

[0043] In the related art, usually, the pipe diameter of the pipeline connected to different liquid cooling plates in the pipeline structure is adjusted, or the inner diameter of the three-way or four-way joint connecting the main pipeline and the branch pipeline is adjusted to adjust the flow rate of the coolant flowing into different liquid cooling plates. This way of adjusting the coolant flow rate will increase the complexity of the pipeline structure and lead to an increase in the cost of the pipeline structure.

[0044] Taking the pipeline structure 110 provided in the embodiment of the present application as an example: the flow rate of the coolant in the main pipeline 111 diverted into different branch pipelines 112 can be adjusted by adjusting the pipe diameter of each branch pipeline 112 or the inner diameter of the diversion pipe 1132 of the three-way or four-way joint (adapter 113) connecting the main pipeline 111 and the branch pipeline 112, and then the flow rate of the coolant flowing into the cooling flow channel of each liquid cooling plate 121 can be adjusted. However, this way of adjusting the pipe diameter of each branch pipeline 112 or the inner diameter of the three-way or four-way joint will increase the complexity of the pipeline structure 110, and corresponding processing molds need to be designed for the branch pipelines 112 or three-way or four-way joints with different pipe diameters, resulting in an increase in the processing cost of the pipeline structure 110. Moreover, during the assembly process of the pipeline structure 110, it is easy to have incorrect assembly positions of the branch pipelines 112, resulting in the diversion ratio of the pipeline structure 110 to the coolant not conforming to the actual situation.

[0045] To improve the above problems, an embodiment of the present application provides a flow regulator, which is configured to regulate the liquid flow in a pipeline.

[0046] As Figures 3 to 6 shown, the flow regulator 130 includes a flow blocking portion 131 and two connecting portions 132 connected to each other. The two connecting portions 132 are arranged along the length direction of the flow blocking portion 131. There is a gap 134 between each of the two connecting portions 132 and the flow blocking portion 131, and the gap 134 can allow liquid to flow through. Among them, the two connecting portions 132 of the flow regulator 130 are configured to be connected to the inner peripheral surface of the pipeline, and the flow blocking portion 131 of the flow regulator 130 is configured to form a channel 1100 for liquid to flow through between it and the inner peripheral surface of the pipeline, and the channel 1100 communicates with the gap 134.

[0047] Thus, the flow regulator 130 can be disposed in the pipeline, so that the two connecting portions 132 of the flow regulator 130 are connected to the inner peripheral surface of the pipeline, and a channel 1100 for liquid to flow through is formed between the flow blocking portion 131 and the inner peripheral surface of the pipeline. Moreover, by changing the area of the radial cross-section of the flow blocking portion 131 of the flow regulator 130, the cross-sectional area of the channel 1100 for liquid to flow through formed between the flow blocking portion 131 and the inner peripheral surface of the pipeline can be adjusted, thereby regulating the flow rate of the coolant flowing through the channel 1100.

[0048] Therefore, by arranging the flow regulators 130 in different pipelines and making the areas of the radial cross-sections of the flow blocking portions 131 of different flow regulators 130 different, the cross-sectional areas of the channels 1100 for coolant to flow through in different pipelines can be made different, thereby realizing the regulation of the coolant flow in different pipelines. This way of regulating the coolant flow in the pipeline structure 110 does not require adjusting the pipe diameter of the pipeline or the inner diameters of tees and crosses (adapter 113). The complexity of the pipeline structure 110 is low, which is beneficial to reducing the cost of the pipeline structure 110. Moreover, the structure of the flow regulator 130 is relatively simple, easy to process, and has little impact on increasing the cost of the pipeline structure 110.

[0049] It should be noted that the area of the radial cross-section of the flow blocking portion 131 refers to the cross-sectional area of the flow blocking portion 131 perpendicular to its length direction.

[0050] In some embodiments, the two connecting portions 132 of the flow regulator 130 can be connected to both ends of the flow blocking portion 131 in the length direction, so that the end positions of the flow blocking portion 131 of the flow regulator 130 in the length direction are kept stable and are not easily shaken under the impact of the coolant, which is beneficial to improving the stability of the liquid cooling assembly 100.

[0051] In some embodiments, the connecting portion 132 can extend along the circumferential direction of the flow blocking portion 131, and the surface of the connecting portion 132 facing away from the flow blocking portion 131 is arranged to abut against the inner circumferential surface of the pipeline. Thus, the abutting area between the connecting portion 132 and the inner circumferential surface of the pipeline can be increased, thereby improving the connection stability between the flow regulating member 130 and the pipeline. Specifically, the connecting portion 132 extends along the circumferential direction of the flow blocking portion 131 to form an annular structure. The flow blocking portion 131 is a cylindrical structure. The connecting portion 132 is an annular structure. A gap 134 for liquid to flow through is formed between the outer circumferential surface of the connecting portion 132 and the flow blocking portion 131.

[0052] In some embodiments, the connecting portion 132 and the flow blocking portion 131 are connected by a plurality of connecting segments 133, and the plurality of connecting segments 133 are arranged at intervals along the circumferential direction of the connecting portion 132. Thus, while the connecting portion 132 and the flow blocking portion 131 can be connected, a gap 134 for liquid to flow through is also formed between the connecting portion 132 and the flow blocking portion 131.

[0053] The embodiment of the present application also provides a liquid cooling assembly, which includes a flow regulating member. The specific structure of the flow regulating member refers to the above embodiments. Since this liquid cooling assembly adopts all the technical solutions of the above all embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, and will not be elaborated herein one by one.

[0054] Among them, as Figures 1 to 5 shown, the liquid cooling assembly 100 includes a flow regulating member 130, a pipeline structure 110, and a plurality of liquid cooling plates 121. The pipeline structure 110 includes a main pipeline 111 and a plurality of branch pipelines 112. The plurality of branch pipelines 112 are respectively communicated with the main pipeline 111 and are sequentially distributed along the length direction of the main pipeline 111. A cooling flow channel is provided in the liquid cooling plate 121, and each branch pipeline 112 is respectively communicated with the cooling flow channel of at least one liquid cooling plate 121.

[0055] Among them, a flow regulating member 130 is provided in at least one branch pipeline 112. The inner circumferential surface of the branch pipeline 112 is connected to the two connecting portions 132 of the flow regulating member 130, and a channel 1100 for liquid to flow through is formed between the inner circumferential surface of the branch pipeline 112 and the flow blocking portion 131 of the flow regulating member 130. Thus, by changing the radial cross-sectional area of the flow blocking portion 131 of the flow regulating member 130, the coolant flow rate in the corresponding branch pipeline 112 can be adjusted without adjusting the pipe diameter of the branch pipeline 112, thereby reducing the complexity of the pipeline structure 110 and further reducing the cost of the pipeline structure 110. Moreover, during the assembly of the pipeline structure 110, since the specifications of the branch pipelines 112 can be kept unified, the situation of misplacing the positions of the branch pipelines 112 will not occur.

[0056] In some embodiments, flow regulators 130 may be provided in at least two branch pipelines 112, and the radial cross-sectional areas of the flow-blocking portions 131 of at least two flow regulators 130 are different. Thus, the coolant flow rates in multiple branch pipelines 112 can be adjusted.

[0057] Of course, flow regulators 130 may also be provided in at least two branch pipelines 112, and the radial cross-sectional areas of the flow-blocking portions 131 of the flow regulators 130 in at least two branch pipelines 112 are the same, so that the coolant flow rates in at least two branch pipelines 112 are kept substantially consistent.

[0058] In some embodiments, as Figures 3 to 5 shown, the pipeline structure 110 includes an adapter 113, and the adapter 113 includes a connecting pipe 1131 and a shunt pipe 1132. One end of the shunt pipe 1132 is communicated with the connecting pipe 1131. The connecting pipe 1131 is located in the main pipeline 111, and the shunt pipe 1132 is located in the branch pipeline 112. The coolant in the main pipeline 111 is shunted into the shunt pipe 1132 located in the branch pipeline 112 through the connecting pipe 1131 to achieve the shunting of the coolant.

[0059] Among them, a flow regulator 130 may be provided in the shunt pipe 1132, and a channel 1100 is formed between the inner peripheral surface of the shunt pipe 1132 and the flow-blocking portion 131. Thus, the flow regulator 130 can be installed into the shunt pipe 1132 through the opening 1133 at the end of the shunt pipe 1132 far from the connecting pipe 1131, and the operation is very convenient.

[0060] Among them, two limiting portions 1134 may be convexly provided on the inner peripheral surface of the shunt pipe 1132, and the two limiting portions 1134 are arranged at intervals along the length direction of the shunt pipe 1132. Two connecting portions 132 are located between the two limiting portions 1134, and the two limiting portions 1134 are used to abut against the two connecting portions 132 in one-to-one correspondence to limit the moving distance of the flow regulator 130 in the length direction of the shunt pipe 1132. Thus, the movement of the flow regulator 130 in the shunt pipe 1132 along the length direction of the shunt pipe 1132 can be limited by the two limiting portions 1134, preventing the flow regulator 130 from coming out of the shunt pipe 1132 and losing the flow regulating function, or preventing the flow regulator 130 from entering the branch pipeline 112 and hindering the coolant flow in the branch pipeline 112.

[0061] In some embodiments, as Figure 5 shown, a chamfer 1135 may be provided at the opening 1133 at the end of the shunt pipe 1132 far from the connecting pipe 1131, and the chamfer 1135 can guide the flow regulator 130 to make it easier to install the flow regulator 130 into the shunt pipe 1132.

[0062] The embodiment of the present application further provides an energy storage system, which includes a liquid cooling component. The specific structure of the liquid cooling component refers to the above embodiment. Since this energy storage system adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0063] Among them, the energy storage system includes a liquid cooling component 100 and a plurality of battery modules, and each battery module is connected to at least one liquid cooling plate 121 of the liquid cooling component 100. Specifically, the plurality of battery modules are connected to the plurality of liquid cooling plates 121 in a one-to-one correspondence, where the battery modules are arranged on one side plate surface of the corresponding liquid cooling plate 121 to facilitate the liquid cooling plate 121 to cool the battery modules.

[0064] The above has introduced the embodiments of the present application in detail. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those skilled in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
