Embodiments of the present invention

[0026] This application provides a flow regulating component, a liquid cooling assembly, and an energy storage system.

[0027] Figure 1 is a structural schematic diagram of some implementations of the liquid cooling assembly provided in this application. As shown in Figure 1, the liquid cooling assembly 100 includes a pipe structure 110 and multiple liquid cooling plates 121. The liquid cooling plates 121 are provided with cooling channels (not shown in the figure). The pipe structure 110 is connected to the cooling channels of the multiple liquid cooling plates 121, thereby providing coolant to the cooling channels of the multiple liquid cooling plates 121 through the pipe structure 110. The liquid cooling plates 121 are configured to be connected to the battery module (not shown in the figure) of the energy storage system to cool the battery module.

[0028] The energy storage system can include multiple battery modules, each connected to a corresponding liquid cooling plate 121, so that each liquid cooling plate 121 cools its corresponding battery module. Specifically, as shown in Figure 1, the multiple liquid cooling plates 121 are divided into multiple liquid cooling plate groups 120, each liquid cooling plate group 120 including multiple liquid cooling plates 121 spaced apart along the height direction of the energy storage system, and each liquid cooling plate 121 is equipped with a battery module.

[0029] Referring again to Figure 1, the piping structure 110 may include a main pipe 111 and multiple branch pipes 112. The branch pipes 112 are connected to the main pipe 111 and are distributed sequentially along the length of the main pipe 111. Each branch pipe 112 is connected to the cooling channel of at least one liquid-cooled plate 121. Thus, coolant can flow between the cooling channel of the liquid-cooled plate 121 and the main pipe 111 through the branch pipes 112. The main pipe 111 can be an inlet pipe, with coolant in the main pipe 111 distributed to different cooling channels of the liquid-cooled plate 121 through the multiple branch pipes 112. Alternatively, the main pipe 111 can also be an outlet pipe, with coolant in the cooling channel of the liquid-cooled plate 121 flowing into the main pipe 111 through the branch pipes.

[0030] Specifically, the piping structure 110 can include multiple main pipes 111, each of which is connected to multiple branch pipes 112. The inlets of the cooling channels of the multiple liquid cooling plates 121 of the liquid cooling plate assembly 120 are connected to one main pipe 111 via branch pipes 112, thereby diverting the coolant in the main pipe 111 to the cooling channels of the multiple liquid cooling plates 121 of the liquid cooling plate assembly 120 via the multiple branch pipes 112. The outlets of the cooling channels of the multiple liquid cooling plates 121 of the liquid cooling plate assembly 120 are connected to another main pipe 111 via another branch pipe 112, thereby allowing the coolant in the cooling channels of the multiple liquid cooling plates 121 of the liquid cooling plate assembly 120 to flow back to the other main pipe 111 via the other branch pipes 112, thus achieving the circulation of coolant to the liquid cooling plates 121 through the piping structure 110.

[0031] The main pipeline 111 extends along the height of the energy storage system, and multiple branch pipelines 112 are distributed sequentially along the length of the corresponding main pipeline 111.

[0032] The temperature of battery modules in different locations of the energy storage system will also vary. In order to ensure that the liquid cooling component 100 has a good cooling effect on each battery module, it is necessary to adjust the flow rate of the coolant that is distributed to different liquid cooling plates 121 in the pipeline structure 110, so as to adjust the cooling effect of different liquid cooling plates 121.

[0033] For example, more coolant in the pipe structure 110 can be diverted to the liquid cooling plate 121 corresponding to the battery module with a higher temperature, while less coolant in the pipe structure 110 can be diverted to the liquid cooling plate 121 corresponding to the battery module with a relatively lower temperature. This results in better cooling of the liquid cooling plate 121 corresponding to the battery module with a relatively higher temperature, while reducing the cooling effect of the liquid cooling plate 121 corresponding to the battery module with a relatively lower temperature. This allows for precise control of the cooling effect of each battery module, which helps to reduce the temperature difference between multiple battery modules and improve the overall performance of the energy storage system.

[0034] Furthermore, the coolant pressure varies at different locations within the piping structure 110, resulting in different flow rates of coolant diverted to the liquid cooling plate 121 at different locations within the piping structure 110. Therefore, it is necessary to adjust the flow rates of the coolant diverted to different liquid cooling plates 121 within the piping structure 110 to ensure that the coolant flow rate within the cooling channels of the liquid cooling plate 121 matches the required cooling effect of the liquid cooling plate 121.

[0035] In related technologies, the diameter of the pipes connected to different liquid cooling plates in the piping structure is usually adjusted, or the inner diameter of the tees or crosses connecting the main pipe and branch pipes is adjusted, in order to regulate the flow rate of coolant distributed to different liquid cooling plates. This method of regulating coolant flow rate increases the complexity of the piping structure, leading to an increase in the cost of the piping structure.

[0036] Taking the pipe structure 110 provided in this application as an example: the flow rate of coolant in the main pipeline 111 to different branch pipelines 112 can be adjusted by changing the diameter of each branch pipeline 112 or the inner diameter of the tee or cross (adapter 113) connecting the main pipeline 111 and the branch pipelines 112, thereby adjusting the flow rate of coolant entering the cooling channel of each liquid cooling plate 121. However, this method of adjusting the diameter of each branch pipeline 112 or the inner diameter of the tee or cross increases the complexity of the pipe structure 110, requiring the design of corresponding processing molds for branch pipelines 112 or tee or cross with different diameters, leading to an increase in the processing cost of the pipe structure 110. Moreover, during the assembly process of the pipe structure 110, it is easy to make mistakes in the assembly position of the branch pipelines 112, resulting in the coolant distribution ratio of the pipe structure 110 not matching the actual value.

[0037] To address the aforementioned issues, this application provides a flow regulator configured to regulate the flow rate of liquid within a pipeline.

[0038] As shown in Figures 3 to 6, the flow regulating component 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, and a gap 134 is formed between each of the two connecting portions 132 and the flow-blocking portion 131, which allows liquid to flow. The two connecting portions 132 of the flow regulating component 130 are configured to connect to the inner circumferential surface of the pipeline, and the flow-blocking portion 131 of the flow regulating component 130 is configured to form a channel 1100 for liquid flow between itself and the inner circumferential surface of the pipeline. This channel 1100 communicates with the gap 134.

[0039] Therefore, the flow regulating element 130 can be installed inside the pipeline, with its two connecting portions 132 connected to the inner circumferential surface of the pipeline, and the flow-blocking portion 131 forming a channel 1100 for liquid flow between itself and the inner circumferential surface of the pipeline. Moreover, by changing the radial cross-sectional area of ​​the flow-blocking portion 131 of the flow regulating element 130, the cross-sectional area of ​​the channel 1100 for liquid flow between the flow-blocking portion 131 and the inner circumferential surface of the pipeline can be adjusted, thereby regulating the flow rate of the coolant flowing through the channel 1100.

[0040] Therefore, by installing flow regulating components 130 in different pipelines and making the radial cross-sectional area of ​​the flow-blocking part 131 of the different flow regulating components 130 different, the cross-sectional area of ​​the channel 1100 for coolant flow in different pipelines can be made different, thereby achieving the regulation of coolant flow in different pipelines. This method of regulating coolant flow in pipeline structure 110 does not require adjusting the pipe diameter or the inner diameter of the tee or cross (adapter 113), resulting in low complexity of pipeline structure 110 and reducing its cost. Moreover, the flow regulating component 130 has a relatively simple structure, is easy to manufacture, and has little impact on increasing the cost of pipeline structure 110.

[0041] It should be noted that the radial cross-sectional area of ​​the flow-blocking part 131 refers to the cross-sectional area of ​​the flow-blocking part 131 perpendicular to its length direction.

[0042] In some implementations, the two connecting portions 132 of the flow regulating member 130 can be connected to the two ends of the flow blocking portion 131 in the length direction, so that the end position of the flow blocking portion 131 of the flow regulating member 130 in the length direction remains stable and is not easy to shake under the impact of the coolant, which is beneficial to improving the stability of the liquid cooling assembly 100.

[0043] In some implementations, the connecting portion 132 can extend circumferentially along the flow-blocking portion 131, and the surface of the connecting portion 132 facing away from the flow-blocking portion 131 can be configured to abut against the inner circumferential surface of the pipeline. This increases the contact area between the connecting portion 132 and the inner circumferential surface of the pipeline, thereby improving the connection stability between the flow regulating element 130 and the pipeline. Specifically, the connecting portion 132 extends circumferentially along the flow-blocking portion 131 in an annular structure. The flow-blocking portion 131 has a cylindrical structure. The connecting portion 132 has an annular structure. A gap 134 for liquid flow is formed between the connecting portion 132 and the outer circumferential surface of the flow-blocking portion 131.

[0044] In some implementations, the connecting portion 132 and the flow-blocking portion 131 are connected by a plurality of connecting segments 133, which are spaced apart circumferentially along the connecting portion 132. Thus, while connecting the connecting portion 132 and the flow-blocking portion 131, a gap 134 for liquid flow is formed between the connecting portion 132 and the flow-blocking portion 131.

[0045] This application also provides a liquid cooling assembly, which includes a flow regulating element. The specific structure of the flow regulating element is as described in the above embodiments. Since this liquid cooling assembly adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0046] As shown in Figures 1 to 5, the liquid cooling assembly 100 includes a flow regulating component 130, a piping structure 110, and multiple liquid cooling plates 121. The piping structure 110 includes a main pipe 111 and multiple branch pipes 112. The multiple branch pipes 112 are respectively connected to the main pipe 111 and are distributed sequentially along the length of the main pipe 111. The liquid cooling plates 121 are provided with cooling channels, and each branch pipe 112 is respectively connected to the cooling channel of at least one liquid cooling plate 121.

[0047] The system includes at least one flow regulator 130 within a branch pipe 112. The inner circumferential surface of the branch pipe 112 is connected to two connecting portions 132 of the flow regulator 130, forming a channel 1100 for liquid flow between the inner circumferential surface of the branch pipe 112 and the flow-blocking portion 131 of the flow regulator 130. Thus, by changing the radial cross-sectional area of ​​the flow-blocking portion 131 of the flow regulator 130, the coolant flow rate within the corresponding branch pipe 112 can be adjusted without adjusting the pipe diameter of the branch pipe 112, thereby reducing the complexity of the piping structure 110 and consequently lowering its cost. Furthermore, during the assembly of the piping structure 110, the specifications of the branch pipes 112 can be kept uniform, preventing incorrect installation of the branch pipes 112.

[0048] In some implementations, at least two branch pipes 112 may be provided with flow regulating elements 130, and the radial cross-sectional areas of the flow obstruction portions 131 of the at least two flow regulating elements 130 are different. This allows for the regulation of the coolant flow rate within the multiple branch pipes 112.

[0049] Of course, at least two branch pipes 112 may be provided with flow regulating elements 130, and the radial cross-sectional area of ​​the flow obstruction portion 131 of the flow regulating elements 130 in at least two branch pipes 112 may be the same, so that the coolant flow rate in at least two branch pipes 112 remains basically consistent.

[0050] In some implementations, as shown in Figures 3 to 5, the piping structure 110 includes an adapter 113, which includes a connecting pipe 1131 and a branch pipe 1132. One end of the branch pipe 1132 is connected to the connecting pipe 1131. The connecting pipe 1131 is located in the main pipeline 111, and the branch pipe 1132 is located in the branch pipeline 112. The coolant in the main pipeline 111 is diverted through the connecting pipe 1131 to the branch pipe 1132 located in the branch pipeline 112 to achieve coolant diversion.

[0051] A flow regulating component 130 can be provided inside the diversion pipe 1132, and a channel 1100 is formed between the inner circumferential surface of the diversion pipe 1132 and the flow obstruction part 131. Thus, the flow regulating component 130 can be installed into the diversion pipe 1132 through the opening 1133 at the end of the diversion pipe 1132 away from the connecting pipe 1131, which is very convenient to operate.

[0052] Two limiting portions 1134 are provided on the inner circumferential surface of the branch pipe 1132, and these two limiting portions 1134 are spaced apart along the length direction of the branch pipe 1132. Two connecting portions 132 are located between the two limiting portions 1134, and the two limiting portions 1134 are configured to abut against the two connecting portions 132 one-to-one to limit the movement distance of the flow regulating member 130 in the length direction of the branch pipe 1132. Thus, the movement of the flow regulating member 130 in the branch pipe 1132 along the length direction of the branch pipe 1132 can be limited by the two limiting portions 1134, preventing the flow regulating member 130 from falling out of the branch pipe 1132 and losing its flow regulating function, or preventing the flow regulating member 130 from entering the branch pipe 112 and obstructing the flow of coolant in the branch pipe 112.

[0053] In some implementations, as shown in Figure 5, a chamfer 1135 can be provided at the opening 1133 at the end of the diverter 1132 away from the connecting pipe 1131. This chamfer 1135 can guide the flow regulator 130, making it easier to install the flow regulator 130 into the diverter 1132.

[0054] This application also provides an energy storage system, which includes a liquid cooling component. The specific structure of the liquid cooling component is as described in the above embodiments. Since this energy storage system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0055] The energy storage system includes a liquid cooling assembly 100 and multiple battery modules, each battery module being connected to at least one liquid cooling plate 121 of the liquid cooling assembly 100. Specifically, the multiple battery modules are connected to the multiple liquid cooling plates 121 in a one-to-one correspondence, wherein the battery modules are disposed on one side of the corresponding liquid cooling plate 121 to facilitate the liquid cooling plate 121 to cool and dissipate heat from the battery modules.
