Description

Technical Field

[0002] A battery energy storage system is a system that uses batteries as the main energy storage medium. It can store electrical energy and release it when needed.

[0003] Battery energy storage systems of related technologies typically include a prefabricated compartment and multiple battery packs installed within it. During the charging and discharging process, the battery packs generate heat. If the heat is too high, it will affect the performance and lifespan of the battery packs. Therefore, a liquid cooling system is required to cool the battery packs. The liquid cooling system includes a return water point and multiple circulation pipes. The coolant after cooling the batteries flows sequentially through the outlet of the battery cooling plate and the condenser into the circulation pipes. The coolant in the multiple circulation pipes is collected in the return water point and then transported to the evaporator for further cooling.

[0004] However, since the return water point is fixed in a predetermined position inside the prefabricated compartment, when multiple circulation pipes are arranged inside the prefabricated compartment, due to the large number of devices inside the prefabricated compartment, the circulation pipes need to bypass some devices inside the prefabricated compartment to connect with the same return water point, which increases the length of the circulation pipes and makes it inconvenient to arrange multiple circulation pipes. Utility Model Content

[0005] This application provides a liquid cooling system for prefabricated energy storage compartments to solve the technical problem that the circulation pipes in related technologies need to bypass certain equipment inside the prefabricated compartment, which makes it inconvenient to arrange multiple circulation pipes.

[0006] This application provides a liquid cooling system for a prefabricated energy storage compartment, including an evaporation assembly, a condensation assembly, and a battery cooling return water pipe. The liquid outlet of the evaporation assembly is connected to the liquid inlet of a plurality of battery cooling plates. A plurality of first regulating components are connected to the battery cooling return water pipe. The liquid inlet of the evaporation assembly is connected to the battery cooling return water pipe. The plurality of first regulating components are respectively connected to the liquid outlet of a plurality of battery cooling plates. The first regulating components are used to regulate the flow rate of the coolant. The condensation assembly is connected to the evaporation assembly to reduce the temperature of the coolant entering the evaporation assembly.

[0016] This application provides a liquid cooling system for a prefabricated energy storage compartment. An evaporation assembly delivers low-temperature coolant to the battery cooling plates, thereby cooling the battery pack. The heated coolant then enters multiple first regulating components from the outlet of the battery cooling plates and re-enters the evaporation assembly via the battery cooling return pipe. A condensation assembly cools the coolant, and the cooled coolant then re-enters the battery cooling plates through the evaporation assembly, thus circulating the coolant to cool the battery pack. By employing multiple first regulating components, the outlets of the multiple battery cooling plates are aligned with the various points on the battery cooling return pipe. The connection is made so that the outlets of multiple battery cooling plates do not need to be converged at the same return point, shortening the arrangement length of multiple pipelines between the outlets of multiple battery cooling plates and multiple first regulating components. This also eliminates the need for the pipelines between the outlets of multiple battery cooling plates and multiple first regulating components to bypass certain equipment in the prefabricated compartment, making it easier to arrange multiple pipelines between the outlets of multiple battery cooling plates and multiple first regulating components in the prefabricated compartment. Furthermore, by using the first regulating components, the flow rate of coolant entering the battery cooling return water pipe can be adjusted, thereby indirectly improving the delivery efficiency of the evaporation component to the battery cooling plates.

[0033] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0034] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0035] As described in the background section, battery energy storage systems of the relevant technology typically include a prefabricated compartment and multiple battery packs installed within the prefabricated compartment. During the charging and discharging process, the battery packs generate heat. If the heat is too high, it will affect the performance and lifespan of the battery packs. Therefore, a liquid cooling system is required to cool the batteries. The liquid cooling system includes a return water point and multiple circulation pipes. The coolant after cooling the batteries flows sequentially through the outlet end of the battery cooling plate and the condenser into the circulation pipes. The coolant in the multiple circulation pipes is collected in the return water point and then transported to the evaporator for further cooling.

[0036] However, since the return water point is fixed in a predetermined position within the prefabricated compartment, when multiple circulation pipes are arranged within the prefabricated compartment, due to the large number of devices inside, the circulation pipes need to bypass some devices within the prefabricated compartment to connect with the same return water point. For example, when the return water point is set at one end of the prefabricated compartment, the circulation pipes on the battery packs that are far from the return water point in multiple battery packs need to cross multiple battery packs to connect with the return water point, increasing the length of the circulation pipes and making it inconvenient to arrange multiple circulation pipes.

[0037] To address the aforementioned technical problems, this application provides a liquid cooling system for a prefabricated energy storage compartment. By employing multiple first adjusting components, the liquid outlets of multiple battery cooling plates are connected to various locations on the battery cooling return water pipe. This eliminates the need to converge the liquid outlets of multiple battery cooling plates at a single return water point, shortening the length of the multiple pipelines between the liquid outlets of the multiple battery cooling plates and the multiple first adjusting components. Furthermore, it eliminates the need for the pipelines between the liquid outlets of the multiple battery cooling plates and the multiple first adjusting components to bypass certain equipment within the prefabricated compartment, facilitating the arrangement of the multiple pipelines between the liquid outlets of the multiple battery cooling plates and the multiple first adjusting components within the prefabricated compartment. The coolant within the evaporation assembly can flow along the battery cooling... The water inlet pipe enters into multiple second regulating components, and then enters into the liquid inlet of multiple battery cooling plates through these components, achieving separate cooling for multiple battery packs and indirectly improving the cooling efficiency of multiple battery packs. By using multiple first connectors, the liquid outlets of multiple inverter cooling pipes are connected to various positions on the inverter cooling return water pipe, thus eliminating the need to collect the liquid outlets of multiple inverter cooling pipes at a single return water point, thereby facilitating the connection between the liquid outlets of multiple inverter cooling pipes and multiple first connectors. By using multiple second connectors, the coolant enters into the liquid inlet of multiple inverter cooling pipes through these second connectors, indirectly improving the cooling efficiency of the inverter.

[0038] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0039] A liquid cooling system for a prefabricated energy storage compartment includes an evaporation assembly 100, a condensation assembly 200, and a battery cooling return water pipe 300. The liquid outlet of the evaporation assembly 100 is connected to the liquid inlet of a plurality of battery cooling plates 720. A plurality of first regulating members 310 are connected to the battery cooling return water pipe 300. The liquid inlet of the evaporation assembly 100 is connected to the battery cooling return water pipe 300. The plurality of first regulating members 310 are respectively connected to the liquid outlet of the plurality of battery cooling plates 720. The first regulating members 310 are used to regulate the flow rate of the coolant. The condensation assembly 200 is connected to the evaporation assembly 100 to reduce the temperature of the coolant entering the evaporation assembly 100.

[0040] In this embodiment, the evaporation assembly 100 is configured as an evaporator, and the condensation assembly 200 is configured as a condenser. After the battery cooling plate 720 absorbs the heat from the battery pack 710, it can transfer this heat to the coolant in the evaporator, thereby reducing the temperature of the battery cooling plate 720. When the coolant flows to the condenser, it is cooled again by the condenser. The number of the first adjusting members 310 can be adjusted adaptively as needed.

[0041] By adopting the above technical solution, the evaporation assembly 100 can deliver low-temperature coolant to the battery cooling plate 720, thereby enabling the battery cooling plate 720 to cool the battery pack 710. The heated high-temperature coolant can enter multiple first regulating members 310 from the outlet end of the battery cooling plate 720, and then re-enter the evaporation assembly 100 through the battery cooling return water pipe 300. The condensation assembly 200 cools the high-temperature coolant, and the cooled coolant can then re-enter the battery cooling plate 720 through the evaporation assembly 100, thus circulating the coolant to cool the battery pack 710. By using multiple first regulating members 310, the outlet ends of the multiple battery cooling plates 720 and various positions on the battery cooling return water pipe 300 are aligned. The connection eliminates the need to converge the outlets of multiple battery cooling plates 720 at a single return point, shortening the length of the multiple pipes between the outlets of the multiple battery cooling plates 720 and the multiple first adjusting members 310. This also eliminates the need for the pipes between the outlets of the multiple battery cooling plates 720 and the multiple first adjusting members 310 to bypass certain equipment within the prefabrication chamber 700, facilitating the arrangement of the multiple pipes between the outlets of the multiple battery cooling plates 720 and the multiple first adjusting members 310 within the prefabrication chamber 700. Furthermore, by employing the first adjusting member 310, the flow rate of the coolant entering the battery cooling return water pipe 300 can be adjusted, thereby indirectly improving the delivery efficiency of the evaporation assembly 100 to the battery cooling plates 720. The first adjusting member 310 includes a first reducing male connector 311.

[0042] In this embodiment, the diameter of the first variable diameter male connector 311 gradually increases from the liquid outlet end of the battery cooling plate 720 toward the battery cooling return water pipe 300, thereby increasing the flow rate of the coolant in the battery cooling return water pipe 300, which facilitates the cooling of the coolant and its return to the evaporator.

[0043] By adopting the above technical solution and by setting the first variable diameter male connector 311, the flow rate of the coolant can be adjusted by changing the diameter of the first variable diameter male connector 311. The structure is simple, the effect of adjusting the flow rate of the coolant is improved, and it is easy to make the flow rate of the coolant at each position of the first adjusting component 310 on the battery cooling return pipe 300 the same.

[0044] The liquid cooling system for the prefabricated energy storage compartment also includes a battery cooling water inlet pipe 400. The liquid outlet end of the evaporation assembly 100 is connected to the battery cooling water inlet pipe 400. Multiple second adjusting members 410 are connected to the battery cooling water inlet pipe 400. The multiple second adjusting members 410 are used to connect to the liquid inlet ends of multiple battery cooling plates 720 respectively. The second adjusting members 410 are used to adjust the flow rate of the coolant. In this embodiment, the number of second adjusting members 410 can be adjusted adaptively as needed.

[0045] By adopting the above technical solution, the coolant in the evaporation component 100 can enter the multiple second regulating members 410 along the battery cooling water inlet pipe 400, and then enter the liquid inlet end of the multiple battery cooling plates 720 through the multiple second regulating members 410, thereby realizing the branch cooling of the multiple battery packs 710 and indirectly improving the cooling efficiency of the multiple battery packs 710; and the arrangement of multiple second regulating members 410 can regulate the flow rate of coolant entering the cooling plates of the battery packs 710, thereby making the cooling of the multiple battery plates more even and further improving the cooling efficiency of the multiple cooling packs.

[0046] The second adjusting member 410 includes a second reducing male connector 411.

[0047] In this embodiment, the diameter of the second variable diameter male connector 411 gradually increases from the direction of the battery cooling water inlet pipe 400 toward the liquid inlet end of the battery cooling plate 720. By reducing the diameter of the second variable diameter male connector 411, the speed at which the coolant passes through the battery cooling plate 720 is slowed down, so that the coolant can fully pass through the battery cooling plate 720 to cool the battery pack 710, thereby indirectly improving the cooling efficiency of the battery cooling plate 720.

[0048] By adopting the above technical solution, the flow rate of coolant can be adjusted by changing the diameter of the second variable diameter male connector 411. The structure is simple, the effect of adjusting the flow rate of coolant is improved, and it is easy to ensure that the flow rate of coolant at each position of the second adjusting component 410 on the battery cooling water inlet pipe 400 is the same.

[0049] The battery cooling return pipe 300 includes a plurality of first connecting pipes 320, which are detachably connected to each other. The battery cooling inlet pipe 400 includes a plurality of second connecting pipes 420, which are detachably connected to each other.

[0050] In this embodiment, multiple first connecting pipes 320 are located on the same straight line, and adjacent first connecting pipes 320 are detachably connected by flanges and bolts; multiple second connecting pipes 420 are located on the same straight line, and adjacent second connecting pipes 420 are detachably connected by flanges and bolts; by adopting the method of detachable connection by flanges and bolts, the connection strength and sealing effect of adjacent first connecting pipes 320 and second connecting pipes 420 are improved, and it is convenient to install and disassemble adjacent first connecting pipes 320 and second connecting pipes 420.

[0051] By adopting the above technical solution and by using multiple first connecting pipes 320, it is convenient to assemble battery cooling return water pipes 300 of different lengths, so that battery cooling return water pipes 300 of different lengths are suitable for different numbers of battery packs 710; by using multiple second connecting pipes 420, it is convenient to assemble battery cooling inlet water pipes 400 of different lengths, so that battery cooling inlet water pipes 400 of different lengths are suitable for different numbers of battery packs 710.

[0052] An evaporation assembly 100 is disposed at one end of the prefabrication chamber 700, a condensation assembly 200 is disposed on the top wall of the prefabrication chamber 700, and a battery cooling water return pipe 300 and a battery cooling water inlet pipe 400 are disposed on the bottom wall of the prefabrication chamber 700 along the length of the plurality of battery packs 710. In this embodiment, the battery cooling water return pipe 300 and the battery cooling water inlet pipe 400 are parallel to each other and spaced apart.

[0053] By adopting the above technical solution, by setting the evaporation component 100 at one end of the prefabricated compartment 700 and setting the condensation component 200 on the top wall of the prefabricated compartment 700, it is convenient to connect the battery cooling water return pipe 300 and the battery cooling water inlet pipe 400 with the evaporation component 100, and it is also convenient to connect the evaporation component 100 with the condensation component 200. By setting the battery cooling water inlet pipe 400 along the length direction of the multiple battery packs 710, it is convenient to connect the battery cooling water inlet pipe 400 with the cooling plates of the multiple battery packs 710.

[0054] The liquid cooling system for the prefabricated energy storage compartment also includes an inverter cooling return water pipe 500. The liquid outlet of the evaporation assembly 100 is used to connect with the liquid inlet of multiple inverter cooling pipes 740. Multiple first connectors 510 are connected to the inverter cooling return water pipe 500. The liquid inlet of the evaporation assembly 100 is connected to the inverter cooling return water pipe 500. The multiple first connectors 510 are used to connect with the liquid outlet of multiple inverter cooling pipes 740 respectively.

[0055] In this embodiment, the inverter cooling return water pipe 500 is parallel to the battery cooling inlet water pipe 400, and the number of first connectors 510 can be adjusted as needed. The first connector 510 can be set as one of the following: external thread end-connected water pipe connector, compression fitting water pipe connector, and self-locking water pipe connector. The use of the first connector 510 facilitates the connection between the inverter cooling return water pipe 500 and the liquid outlet of the condenser assembly 200.

[0056] By adopting the above technical solution, the evaporation assembly 100 can deliver low-temperature coolant to the inverter cooling pipe 740, thereby cooling the inverter 730. The heated high-temperature coolant can enter the evaporation assembly 100 from the outlet end of the inverter cooling pipe 740, and the condensation assembly 200 cools the high-temperature coolant in the evaporation assembly 100. The cooled coolant can then re-enter the inverter cooling pipe 740 through the evaporation assembly 100, thus circulating the coolant to cool the inverter 730. By using multiple first connectors 510, multiple inverter cooling pipes can be connected to the evaporation assembly 100. The outlet end of the cooling pipe 740 is connected to various positions on the inverter cooling return water pipe 500, so that the outlet ends of multiple inverter cooling pipes 740 do not need to be gathered at the same return water point. This shortens the arrangement length of multiple pipes between multiple first connectors 510 and multiple outlet ends of multiple inverter cooling pipes 740, and eliminates the need to bypass certain equipment in the prefabricated compartment 700 for the pipes between multiple first connectors 510 and multiple outlet ends of multiple inverter cooling pipes 740. This facilitates the arrangement of multiple pipes between multiple first connectors 510 and multiple outlet ends of multiple inverter cooling pipes 740 in the prefabricated compartment 700.

[0057] The liquid cooling system for the prefabricated energy storage compartment also includes an inverter cooling water inlet pipe 600. The liquid outlet end of the evaporation component 100 is connected to the inverter cooling water inlet pipe 600. Multiple second connectors 610 are connected to the inverter cooling water inlet pipe 600. The multiple second connectors 610 are used to connect to the liquid inlet ends of multiple inverter cooling pipes 740 respectively.

[0058] In this embodiment, the inverter cooling water inlet pipe 600 and the inverter cooling water return pipe 500 are arranged parallel and spaced apart; the number of second connectors 610 can be adjusted as needed; the second connectors 610 can be set as one of external thread end-connected water pipe connectors, compression fitting water pipe connectors and self-locking water pipe connectors, and the use of second connectors 610 facilitates the connection between the inverter cooling water inlet pipe 600 and the inverter cooling pipeline 740.

[0059] By adopting the above technical solution, the coolant in the evaporation component 100 can enter into multiple second connectors 610 along the inverter cooling water inlet pipe 600, and then enter into the liquid inlet of multiple inverter cooling pipes 740 through the multiple second connectors 610, thereby achieving synchronous cooling of multiple inverters 730. By using multiple second connectors 610, the coolant enters into multiple inverter cooling pipes 740 through multiple pipes, indirectly improving the cooling efficiency of multiple inverters 730.

[0060] The inverter cooling return water pipe 500 includes multiple third connecting pipes 520, and adjacent third connecting pipes 520 are detachably connected. The inverter cooling inlet water pipe 600 includes multiple fourth connecting pipes 620, and adjacent fourth connecting pipes 620 are detachably connected.

[0061] In this embodiment, multiple third connecting pipes 520 are located on the same straight line, and adjacent third connecting pipes 520 are detachably connected by flanges and bolts; multiple fourth connecting pipes 620 are located on the same straight line, and adjacent fourth connecting pipes 620 are detachably connected by flanges and bolts; by adopting the method of detachable connection by flanges and bolts, the connection strength and sealing effect of adjacent third connecting pipes 520 and fourth connecting pipes 620 are improved, and it is convenient to install and disassemble adjacent third connecting pipes 520 and fourth connecting pipes 620.

[0062] By adopting the above technical solution and by using multiple third connecting pipes 520, it is convenient to assemble inverter cooling return water pipes 500 of different lengths, so that inverter cooling return water pipes 500 of different lengths can be used for inverters 730 of different shapes and positions; by using multiple fourth connecting pipes 620, it is convenient to assemble inverter cooling inlet water pipes 600 of different lengths, so that inverter cooling inlet water pipes 600 of different lengths can be used for inverters 730 of different shapes and positions.

[0063] Inverter cooling return water pipe 500 and inverter cooling inlet water pipe 600 are installed on the bottom wall of the prefabricated compartment 700 along the length of the multiple battery packs 710.

[0064] By adopting the above technical solution, by setting the inverter cooling return water pipe 500 along the length direction of the multiple battery packs 710, it is convenient to connect the inverter cooling return water pipe 500 with the liquid outlet of the multiple inverter cooling pipes 740; by setting the inverter cooling inlet water pipe 600 along the length direction of the multiple battery packs 710, it is convenient to connect the inverter cooling inlet water pipe 600 with the inverter cooling pipes 740.

[0065] By employing multiple first adjusting members 310, the liquid outlets of multiple battery cooling plates 720 are connected to various locations on the battery cooling return water pipe 300. This eliminates the need to converge the liquid outlets of multiple battery cooling plates 720 at a single return water point, shortening the length of the multiple pipelines between the liquid outlets of multiple battery cooling plates 720 and the multiple first adjusting members 310. Furthermore, it eliminates the need for the pipelines between the liquid outlets of multiple battery cooling plates 720 and the multiple first adjusting members 310 to bypass certain equipment within the prefabrication chamber 700, facilitating the arrangement of the multiple pipelines between the liquid outlets of multiple battery cooling plates 720 and the first adjusting members 310 within the prefabrication chamber 700. The coolant in the evaporation assembly 100 can enter the multiple second adjusting members 410 along the battery cooling inlet water pipe 400. The coolant enters the inlet of the multiple battery cooling plates 720 through multiple second adjusting members 410, thereby achieving branch cooling of the multiple battery packs 710 and indirectly improving the cooling efficiency of the multiple battery packs 710. By using multiple first connectors 510, the outlet of the multiple inverter cooling pipes 740 is connected to various positions on the inverter cooling return water pipe 500, so that the outlet of the multiple inverter cooling pipes 740 does not need to be collected at the same return water point, thus facilitating the connection between the outlet of the multiple inverter cooling pipes 740 and the multiple first connectors 510. By using multiple second connectors 610, the coolant enters the inlet of the multiple inverter cooling pipes 740 through the multiple second connectors 610, indirectly improving the cooling efficiency of the inverter 730.
