Description

Technical Field

[0001] This application relates to the field of battery technology, specifically to a shunt assembly, a temperature regulation system, and a battery pack. Background Technology

[0002] Currently, the mainstream battery cell types on the market include cylindrical cells, prismatic cells, and pouch cells. Large cylindrical cells have higher energy density, better safety and stability, and lower cost, and have been widely used in electric vehicles, gradually becoming the future development trend of electric vehicle batteries.

[0003] Large cylindrical battery pack systems widely employ a serpentine tube liquid cooling plate that contacts the side of the cell for thermal management. The large contact area between the serpentine tube liquid cooling plate and the cell achieves efficient cooling. Furthermore, the parallel liquid cooling system design of the serpentine tubes reduces voltage drop, further improving overall cooling efficiency. However, in related technologies, multiple serpentine tubes are typically connected in parallel with inlet and outlet pipes via connectors. This connection method leads to low assembly efficiency. In addition, the installation of the inlet and outlet pipes, along with related connectors, occupies considerable space, potentially causing space constraints in battery system design. Utility Model Content

[0004] The embodiments of this application provide a temperature regulation system and a battery pack, which can improve the problems of low assembly efficiency and large space occupation of the serpentine tube inlet / outlet liquid structure.

[0005] In a first aspect, embodiments of this application provide a diversion component, including multiple flow collection structures, which are sequentially snapped together along a first direction. Each flow collection structure is provided with a first channel and a second channel that are isolated from each other and extend along the first direction. The first channels of the multiple flow collection structures are sequentially connected along the first direction to form a liquid inlet channel, and the second channels of the multiple flow collection structures are sequentially connected along the first direction to form a liquid outlet channel.

[0006] Each of the aforementioned flow collection structures is provided with a third channel and a fourth channel that are isolated from each other and extend along a second direction. The third channel is connected to the first channel, and the fourth channel is connected to the second channel. The flow collection structure is provided with a plug-in end on one side along the second direction. The plug-in end is used to plug into the end of the temperature regulating plate so that the liquid inlet of the temperature regulating plate is connected to the liquid inlet channel through the third channel, and the liquid outlet of the temperature regulating plate is connected to the liquid outlet channel through the fourth channel.

[0007] One of the flow collection structures is provided with a liquid inlet end, the channel of which is connected to the first channel; the other flow collection structure is provided with a liquid outlet end, the channel of which is connected to the second channel.

[0008] In some embodiments, the flow collection structure includes:

[0009] The current collector includes a first current collector cavity and a second current collector cavity that are isolated from each other, and one end of the current collector is provided with an opening along a second direction;

[0010] The connector is provided with the third channel and the fourth channel. The third channel is connected to the first collection cavity, and the fourth channel is connected to the second collection cavity. The connector includes a first end and a second end distributed along the second direction. The first end is inserted into the end of the collection fluid that has the opening, and the second end is used to connect to the temperature regulating plate.

[0011] A first connector is installed at one end of the current collector along the first direction, and the first connector has a first sub-channel and a second sub-channel.

[0012] The second connector is installed at the other end of the current collector along the first direction, and the second connector has a third sub-channel and a fourth sub-channel.

[0013] Along the first direction, the first connectors of the plurality of current collection structures are engaged with the second connectors of the adjacent current collection structures, and the first sub-channel, the first current collection cavity, and the third sub-channel are sequentially connected to form the first channel, and the second sub-channel, the second current collection cavity, and the fourth sub-channel are sequentially connected to form the second channel.

[0014] In this embodiment, the flow collector structure comprises a flow collector, a connector, a first joint, and a second joint. The flow collector is designed with independent first and second flow collecting chambers, and has an opening at one end along a second direction. The connector is inserted into the opening end of the flow collector via its first end, facilitating assembly between the connector and the flow collector. The second end of the connector is used to connect to a temperature regulating plate. This flow collector is responsible for managing the flow and distribution of the temperature regulating medium within the system, thereby achieving efficient fluid transfer.

[0015] During assembly of the flow divider assembly, the flow collector structure is connected to the second connector of the adjacent flow collector structure via a first connector, thereby connecting the first and second channels of the adjacent flow collector structures. At one end of the flow divider assembly, a first sealing plate is installed on the flow collector structure; at the other end, a second sealing plate is installed, thus forming a complete inlet and outlet channel. The flow collector design is simple and easy to assemble.

[0016] In some embodiments, the current collector is provided with a limiting structure, and the connector is provided with an abutting structure. The limiting structure abuts against the abutting structure to limit the relative movement between the connector and the current collector.

[0017] In some embodiments, the current collector is injection molded to the connector; or, the current collector is bonded to the connector.

[0018] In this embodiment, the current collector and the connector are injection molded together, which makes the processing of the current collector and the connector more convenient and the connection between the current collector and the connector more stable. Alternatively, the current collector and the connector can be bonded together, which makes the connection between the current collector and the connector more convenient.

[0019] In some embodiments, the first connector includes two first sub-connectors, which are movably mounted on one side of the current collector along a first direction. One of the first sub-connectors is provided with a first sub-channel, and the other first sub-connector is provided with a second sub-channel.

[0020] In this embodiment, the first connector includes two first sub-connectors. By allowing the first sub-connectors to move relative to the current collector, when the first connector is connected to the second connector of the adjacent current collector structure, the first sub-channel is connected to the third sub-channel, and the second sub-channel is connected to the fourth sub-channel. The position of the first connector can be adaptively adjusted according to the relative position of the first connector and the second connector of the adjacent current collector structure, so that the first connector can be accurately connected to the second connector of the adjacent current collector structure. This reduces the assembly accuracy requirements of the first connector and the second connector of the adjacent current collector structure and improves the assembly efficiency of the current distribution assembly.

[0021] In some embodiments, the first sub-connector includes a guide segment extending from one end of the first sub-connector away from the current collector toward the current collector, the guide segment having a circumscribed circle diameter that gradually decreases in the direction away from the current collector, and the guide segment being inserted into an adjacent second connector.

[0022] In this embodiment, the first sub-connector includes a guide section. When the first connector is connected to the second connector of the adjacent current collection structure, the outer peripheral surface of the guide section can guide the first connector to be quickly and accurately inserted into the second through hole of the second connector of the adjacent current collection structure, thereby improving the connection efficiency of the two current collection structures.

[0023] In some embodiments, the third sub-channel and the fourth sub-channel of the second connector each include a guide hole segment. The guide hole segment extends from one end of the second connector away from the current collector toward the current collector. The inner diameter of the guide hole segment gradually decreases along the direction close to the current collector. The guide segment of the first connector is inserted into the guide hole segment of the second connector.

[0024] In this embodiment, the second through hole includes a guide hole section. When the first connector is connected to the second connector of the adjacent current collection structure, the inner circumferential surface of the guide hole section can guide and cooperate with the guide section, so that the first connector can be quickly and accurately inserted into the second connector of the adjacent current collection structure, thereby improving the connection efficiency of the two current collection structures.

[0025] In some embodiments, a sealing ring is provided between the first sub-connector and the current collector, the sealing ring is disposed around the first sub-connector, and the first sub-connector and the current collector clamp the sealing ring to form a sealing and protective structure.

[0026] In this embodiment, by making the first sub-connector movable relative to the collector and providing a sealing ring between the first sub-connector and the collector, a sealed protective structure is formed between the first sub-connector and the collector. While the position of the first sub-connector relative to the collector is adjustable, the temperature regulating medium in the first channel and the second channel will not leak out from the gap between the first sub-connector and the collector.

[0027] In some embodiments, the collector structure further includes a connecting structure, wherein the collector is disposed on one side along the first direction, the first sub-connector includes a connecting portion, the connecting portion being movably connected to the connecting structure; the connecting structure includes a limiting member connected to the collector, the limiting member being located on the side of the connecting portion away from the collector, the limiting member abutting against the side of the connecting portion away from the collector, so that the connecting portion and the collector clamp the sealing ring.

[0028] In this embodiment, a thrust can be applied to the connecting part by a limiting member, so that the connecting part and the current collector clamp the sealing ring. While achieving the clamping and fixing of the sealing ring, the number of parts is reduced, making the overall structure of the current collector structure compact.

[0029] In some embodiments, the connection structure further includes a connection protrusion protruding from one side of the current collector along the first direction. The connection protrusion surrounds and forms two grooves. The bottom surfaces of the two grooves are provided with a first interface and a second interface. The first interface communicates with the first current collector cavity, and the second interface communicates with the second current collector cavity. The connection portions of the two first sub-connectors are at least partially accommodated in the corresponding grooves. The first sub-channel communicates with the first interface, and the second sub-channel communicates with the second interface. The limiting member is connected to the connection protrusion.

[0030] In this embodiment, a connecting protrusion is formed on the side of the current collector, and the connecting protrusion surrounds two grooves. The connecting part of the first sub-connector is at least partially accommodated in the corresponding groove, which facilitates the positioning and assembly of the first sub-connector and the current collector. The limiting member is connected to the protrusion mechanism to make the connection between the limiting member and the current collector more convenient and to form a stable limit on the connecting part.

[0031] In some embodiments, the limiting member is disposed around the first sub-connector; the limiting member has a clearance hole for the corresponding first sub-connector to pass through;

[0032] The first sub-connector includes a mating section located within the clearance hole, wherein the inner diameter of the clearance hole is larger than the outer diameter of the mating section; and the outer diameter of the connecting portion is larger than the inner diameter of the clearance hole.

[0033] In this embodiment, the first connector includes a mating section, and the inner diameter of the clearance hole is larger than the outer diameter of the mating section; the outer diameter of the connecting portion is larger than the inner diameter of the clearance hole. This allows the limiting member to have a larger area to abut against the surface of the connecting portion away from the collector fluid, making the limiting member more stably abut against the connecting portion. Furthermore, the clearance hole provides space for the mating section to move and swing radially in the first channel, allowing the first connector to move and swing radially relative to the connecting structure in the first channel. Additionally, it allows the limiting member to abut against the side of the connecting portion away from the collector fluid more stably, preventing the connecting portion from dislodging from the clearance hole.

[0034] In some embodiments, the limiting member has a first engaging portion on the side opposite to the current collector, the second connector has two second engaging portions, the outer wall of the third sub-channel has one second engaging portion, and the outer wall of the fourth sub-channel has one second engaging portion. The second engaging portions engage with the first engaging portions of adjacent current collector structures to limit the relative movement distance between the two current collector structures in the first direction. This makes the connection between the first connector and the second connector of the adjacent current collector structure more stable, reducing the risk of the two current collector structures separating due to opposite movement in the first direction.

[0035] In some embodiments, the first snap-fit ​​portion includes a plurality of first sub-snap-fit ​​portions, which are spaced apart circumferentially along the first sub-connector.

[0036] The second latching portion includes a plurality of second sub-latching portions, which are spaced apart circumferentially along the third sub-channel or the fourth sub-channel;

[0037] The second sub-clamping portion abuts against the corresponding first sub-clamping portion to limit the relative movement distance of the two current collection structures in the first direction.

[0038] In this embodiment of the application, the first snap-fit ​​part includes a plurality of first sub-snap-fit ​​parts, and the second snap-fit ​​part includes a plurality of second sub-snap-fit ​​parts. By having the plurality of first sub-snap-fit ​​parts and the plurality of second sub-snap-fit ​​parts cooperate to snap-fit, the snap-fit ​​and fixation of two adjacent current collector structures is realized, reducing the probability of the two current collector structures becoming detached and improving the connection reliability of the two current collector structures.

[0039] In some embodiments, one of the multiple flow collection structures further includes a third connector, which is disposed on the side of the flow collector opposite to the opening. The third connector has a fifth channel that communicates with the first flow collection cavity or the second flow collection cavity. The third connector is used to connect to an inlet pipe or an outlet pipe.

[0040] In this embodiment, one of the multiple flow collection structures is provided with a third connector, which is connected to the inlet pipe or outlet pipe to realize the inlet or outlet of the flow distribution component. The third connector has a simple structure and facilitates the connection between the flow distribution component and the inlet pipe or outlet pipe.

[0041] In some embodiments, the current collector has a boss on the side near the third connector, the boss extends radially along the fifth channel, the boss extends from one side of the fifth channel into the fifth channel, and the boss portion is located on the extension path of the fifth channel.

[0042] In this embodiment, a boss is provided on the side of the current collector near the third connector. The boss is located on the extension path of the fifth channel. When the flow divider enters or exits, the temperature regulating medium flows through the boss. The boss has a flow limiting function, which reduces the flow resistance and pressure drop in the flow divider.

[0043] In some embodiments, the boss has a through hole, and the through hole communicates with the fifth channel.

[0044] In this embodiment, a through hole is provided on the boss to ensure smooth flow of the temperature regulating medium.

[0045] Secondly, embodiments of this application provide a temperature regulation system, including:

[0046] Inlet pipe;

[0047] Discharge tube;

[0048] Multiple temperature regulating plates are spaced apart along a first direction;

[0049] In any of the above-mentioned diversion components, the inlet pipe is connected to the inlet end, the outlet pipe is connected to the outlet end, the diversion component is installed on one side of the temperature regulating plate along the second direction, and the flow collection structure is inserted into the end of the corresponding temperature regulating plate.

[0050] In some embodiments, a BDU liquid cooling plate is also included, located on one side of the temperature regulating plate along the height direction of the temperature regulating plate, and the BDU liquid cooling plate is connected to the inlet pipe and the outlet pipe.

[0051] In this embodiment, the BDU liquid cooling plate and the flow distribution assembly share the same inlet and outlet pipes, reducing pipe layout and improving space utilization.

[0052] In some embodiments, two flow dividers are included, which are disposed at the ends of corresponding battery modules. The liquid inlet ends of the two flow dividers and the liquid inlet end of the BDU liquid cooling plate are connected to the liquid inlet pipe through a pipe connector, and the liquid outlet ends of the two flow dividers and the liquid outlet end of the BDU liquid cooling plate are connected to the liquid outlet pipe through a pipe connector.

[0053] In this embodiment, the inlet pipe connects to the inlet ends of two shunt components and the inlet end of the BDU liquid cooling plate via pipe fittings, ensuring that the temperature regulating medium can smoothly enter each shunt component for processing. The outlet pipe also connects to the outlet ends of multiple shunt components and the outlet end of the BDU liquid cooling plate via pipe fittings, ensuring that the processed temperature regulating medium can be quickly discharged, thereby guaranteeing the continuity and stability of the system. The assembly method of the inlet pipe, outlet pipe, pipe fittings, and shunt components is simple, improving the assembly efficiency of the battery pack.

[0054] Thirdly, embodiments of this application provide a battery pack including the temperature regulation system described above.

[0055] In some embodiments, a plurality of stacked battery modules are included, each battery module including a plurality of battery packs, and a current shunt assembly is mounted at one end of each battery module. The temperature regulating plate is mounted on both sides of the battery packs in the corresponding battery module.

[0056] In this embodiment, a temperature regulating medium is delivered to the temperature regulating plate corresponding to each battery module through multiple shunt components, thereby achieving temperature regulation of the battery pack and making the battery pack structure compact.

[0057] The beneficial effects of the embodiments of this application are as follows:

[0058] The flow-diverting assembly provided in this embodiment comprises multiple flow-collecting structures sequentially snapped together along a first direction. Each flow-collecting structure has a first channel and a second channel extending along the first direction. The first channels of the multiple flow-collecting structures are continuous along the first direction, forming a continuous liquid inlet channel for conveying the temperature-regulating medium. Simultaneously, the second channels of the multiple flow-collecting structures are also continuous along the first direction, forming a liquid outlet channel for discharging the temperature-regulating medium. This optimizes the flow path of the temperature-regulating medium and improves the overall efficiency of the system.

[0059] In addition, each manifold structure includes a third and a fourth channel extending along the second direction. The first and third channels are connected, allowing the temperature regulating medium to enter the temperature regulating plate through the third channel for heat exchange. The second and fourth channels are connected, allowing the temperature regulating medium that has undergone heat exchange to flow into the outlet channel through the fourth channel, completing the entire temperature regulating medium circulation process. This ensures smooth flow of the temperature regulating medium within the temperature regulating plate and guarantees the effectiveness of temperature regulation.

[0060] Each manifold is equipped with a plug-in terminal that mates with the end of the temperature control plate to ensure a stable and reliable connection. This design not only reduces the space occupied by the temperature control plate end, making the entire structure more compact, but also saves material costs. Furthermore, the assembly of the shunt components is very simple, allowing users to easily install them, greatly reducing assembly time and labor costs. The assembly method with the temperature control plate has also been optimized, significantly improving the assembly efficiency of the entire system and thus enhancing production efficiency.

Detailed Implementation

[0085] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0086] See Figure 1 and Figure 2 This application provides a current collector structure 11, a temperature regulation system 21, and a battery pack 20. These will be described in detail below.

[0087] See Figure 1 and Figure 2 The battery pack 20 includes a battery module 22, which includes multiple battery packs 220. Temperature regulating plates 210 are provided on both sides of the battery packs 220. The outer peripheral surface of the battery packs 220 exchanges heat with the temperature regulating plates 210 to regulate the temperature of the multiple battery modules 22 and keep the multiple battery modules 22 at a suitable operating temperature.

[0088] It should be noted that the temperature regulation system 21 can heat or cool multiple battery modules 22, depending on the ambient temperature of the internal thermometer of the battery pack 20.

[0089] Among them, see Figure 1 and Figure 2 The battery module 22 may include multiple rows of battery packs 220, which are located between temperature regulating plates 210. Multiple cylindrical batteries in the battery packs 220 are arranged sequentially along the second direction Y. The temperature regulating plate 210 has an arc-shaped structure that matches the cylindrical batteries, ensuring a large contact area between the temperature regulating plate 210 and the cylindrical batteries, thus improving the temperature regulation effect of the battery module 22. The temperature regulating plate 210 has flow channels. A flow distribution assembly 10 is connected to the temperature regulating plate 210. The temperature regulating medium in the flow distribution assembly 10 is distributed to different flow channels of the temperature regulating plates 210 through a current collector structure 11, and heat is exchanged between the battery modules 22 of the battery pack 20 through the temperature regulating plates 210 to cool or heat the battery modules 22. The temperature regulating medium can be coolant, refrigerant, etc., and is not limited here.

[0090] To improve the assembly efficiency of the temperature regulating plate 210 and save the space occupied by the liquid inlet and outlet structure of the temperature regulating plate 210, this application provides a flow diversion component 10. The flow diversion component 10 will be described in detail below with reference to the accompanying drawings.

[0091] See Figure 4 , Figure 5 , Figure 8 , Figure 9 and Figure 10 A diversion assembly 10 includes multiple flow-collecting structures 11, each flow-collecting structure 11 having a first channel 12 and a second channel 13 extending along a first direction X, which are mutually isolated from each other. The multiple flow-collecting structures 11 are sequentially connected along the first direction X. The first channels 12 of the multiple flow-collecting structures 11 are sequentially connected along the first direction X to form an inlet channel 23, and the second channels 13 of the multiple flow-collecting structures 11 are sequentially connected along the first direction X to form an outlet channel 24. Each flow-collecting structure 11 has a third channel 14 and a fourth channel 15 extending along a second direction Y, which are mutually isolated from each other. The third channel 14 communicates with the first channel 12, and the fourth channel 15 communicates with the second channel 13. For example, a baffle 16 is formed between the third channel 14 and the fourth channel 15, and the baffle 16 extends along the second direction Y. The flow collector 11 has a plug-in end on one side along the second direction Y. The plug-in end is used to connect with the end of the temperature regulating plate 210, so that the liquid inlet of the temperature regulating plate 210 is connected to the liquid inlet channel 23 through the third channel 14, and the liquid outlet of the temperature regulating plate 210 is connected to the liquid outlet channel 24 through the third channel 14. One of the flow collectors 11 has a liquid inlet end 1174, and the channel in the liquid inlet end 1174 is connected to the first channel 12. The adjacent flow collector 11 has a liquid outlet end 1175, and the channel in the liquid outlet end 1175 is connected to the second channel 13. The first direction X and the second direction Y are set at an angle, such as the first direction X being perpendicular to the second direction Y.

[0092] The diversion assembly 10 provided in this embodiment includes multiple flow-collecting structures 11 sequentially connected along a first direction X. Each flow-collecting structure 11 has a first channel 12 and a second channel 13 extending along the first direction X. The first channels 12 of the multiple flow-collecting structures 11 are continuous along the first direction X, forming a continuous liquid inlet channel 23 for conveying the temperature-regulating medium. Simultaneously, the second channels 13 of the multiple flow-collecting structures 11 are also continuous along the first direction X, forming a liquid outlet channel 24 for discharging the temperature-regulating medium. This optimizes the flow path of the temperature-regulating medium and improves the overall efficiency of the system.

[0093] See Figure 4Each manifold 11 also includes a third channel 14 and a fourth channel 15 extending along the second direction Y. The first channel 12 is connected to the third channel 14, allowing the temperature regulating medium to enter the temperature regulating plate 210 for heat exchange through the third channel 14. The second channel 13 is connected to the fourth channel 15, allowing the temperature regulating medium that has undergone heat exchange to flow into the outlet channel 24 through the fourth channel 15, completing the entire temperature regulating medium circulation process. This ensures smooth flow of the temperature regulating medium within the temperature regulating plate 210 and guarantees the effectiveness of temperature regulation.

[0094] Each manifold 11 is equipped with a plug-in terminal that mates with the end of the temperature regulating plate 210 to ensure a stable and reliable connection. This design not only reduces the space occupied at the end of the temperature regulating plate 210, making the entire structure more compact, but also saves material costs. Furthermore, the assembly of the shunt assembly 10 is very simple, allowing users to easily install it, greatly reducing assembly time and labor costs. The assembly method with the temperature regulating plate 210 has also been optimized, significantly improving the assembly efficiency of the entire system and thus enhancing production efficiency.

[0095] In some embodiments, see Figure 3 and Figure 4 The fluid collection structure 11 includes a collector 110, a connector 116, a first connector 113, and a second connector 115.

[0096] Along the first direction X, the first connector 113 and the second connector 115 are respectively installed on both sides of the current collector 110, so that adjacent current collector structures 11 can be snap-fitted together through the first connector 113 and the second connector 115. This facilitates the assembly of the current collector structure 11 and improves assembly efficiency.

[0097] Along the second direction Y, connector 116 is installed on one side of the manifold 110, and connector 116 is used to connect to the temperature regulating plate 210. This enables the manifold structure 11 to perform effective temperature control during fluid management, helping to maintain fluid stability under different operating conditions. The arrangement of the first connector 113, the second connector 115, and connector 116 on the manifold 110 facilitates the assembly of the manifold structure 11 with each other, as well as the assembly of the manifold structure 11 with the temperature regulating plate 210, improving the assembly efficiency of the flow distribution assembly 10.

[0098] Specifically, see Figure 4The current collector 110 has a first current collecting cavity 1110 and a second current collecting cavity 1111 that are isolated from each other, and has an opening 1120 at one end along the second direction Y. The connector 116 is designed with a third channel 14 and a fourth channel 15 extending along the second direction Y, wherein the third channel 14 communicates with the first current collecting cavity 1110, and the fourth channel 15 communicates with the second current collecting cavity 1111. This ensures that the fluid can be split and merged according to a preset path when passing through the current collector 110, thereby improving the efficiency of the system.

[0099] See Figure 4 The connector 116 includes a first end 1161 and a second end 1162 distributed along the second direction Y. The first end 1161 is inserted into one end of the opening 1120 of the collector 110, and the second end 1162 is used to connect to the temperature regulating plate 210. This design ensures tight coupling between the connector 116 and other components, which not only improves the reliability of the fluid system, but also simplifies the installation and maintenance of the structure.

[0100] See Figure 3 and Figure 5 The first connector 113 has a first sub-channel 1130 and a second sub-channel 1131 extending along a first direction X, and the second connector 115 has a third sub-channel 1151 and a fourth sub-channel 1152 extending along the first direction X. The first sub-channel 1130, the first collecting cavity 1110, and the third sub-channel 1151 are sequentially connected to form the first channel 12, while the second sub-channel 1131, the second collecting cavity 1111, and the fourth sub-channel 1152 are sequentially connected to form the second channel 13. This multi-channel design allows for complex flow and exchange of fluid within the collecting cavity 110, significantly improving the functionality and application range of the collecting structure 11.

[0101] In some embodiments, see Figure 11 , Figure 12 , Figure 13 and Figure 14 The first connector 113 of the flow collection structure 11 at one end of the flow distribution assembly 10 can be replaced with the first sealing plate 118, while the second connector 115 of the flow collection structure 11 at the other end can be replaced with the second sealing plate 119. Through the sealing effect of the first sealing plate 118 and the second sealing plate 119, both ends of the liquid inlet channel 23 and the liquid outlet channel 24 are effectively sealed. Simultaneously, any one of the flow collectors 110 located between the first sealing plate 118 and the second sealing plate 119 can be configured as either the liquid inlet end 1174 or the liquid outlet end 1175 to flexibly adapt to different operational requirements.

[0102] Specifically, see Figure 11 and Figure 12A flow collection structure 11 located at the end of the flow splitting assembly 10 includes a flow collector 110, a connector 116, a second connector 115, and a first sealing plate 118. In the first direction X, the second connector 115 and the first sealing plate 118 are located on both sides of the flow collector 110, and the first sealing plate 118 is connected to the flow collector 110 and seals the side of the first flow collection cavity 1110 and the second flow collection cavity 1111 away from the second connector 115.

[0103] Correspondingly, see Figure 13 and Figure 14 A flow collection structure 11 located at the other end of the flow divider assembly 10 includes a flow collector 110, a connector 116, a first connector 113, and a second sealing plate 119. Along the first direction X, the second sealing plate 119 and the first connector 113 are respectively positioned on both sides of the flow collector 110. The second sealing plate 119 connects to the flow collector 110 and seals the ends of the first flow collection chamber 1110 and the second flow collection chamber 1111 away from the first connector 113. It is worth noting that the first sealing plate 118 or the second sealing plate 119 can be an integral structure with the flow collector 110. This design not only simplifies the manufacturing process but also enhances the overall strength and durability of the structure.

[0104] The structure of the shunt assembly 10 combines equipment assembly, flow management, and temperature regulation functions. Through precise structural layout and multi-channel design, the performance and adaptability of the shunt assembly 10 are significantly improved.

[0105] In some embodiments, see Figure 4 The current collector 110 is provided with a limiting structure 112, and the connector 116 is provided with an abutting structure 1163. The limiting structure 112 abuts against the abutting structure 1163 to limit the relative movement between the connector 116 and the current collector 110.

[0106] For example, see Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The limiting structure 112 includes a first limiting portion 1121, and the abutting structure 1163 includes a first abutting portion 1164. The current collector 110 is provided with the first limiting portion 1121, and the connector 116 is provided with the first abutting portion 1164. The first limiting portion 1121 is located on one side of the first abutting portion 1164 along the second direction Y, so that the first limiting portion 1121 abuts against the first abutting portion 1164 to restrict the connector 116 from moving relative to the current collector 110 along the second direction Y.

[0107] The current collection structure 11 provided in this application embodiment provides a first limiting part 1121 in the current collector 110 and a first abutting part 1164 in the connector 116, and positions the first limiting part 1121 on one side of the first abutting part 1164 along the second direction Y, so that the first limiting part 1121 abuts against the first abutting part 1164 to restrict the connector 116 from moving relative to the current collector 110 along the second direction Y, thereby making the connector 116 and the current collector 110 stably connected together. When the second end 1162 of the connector 116 is connected to the temperature regulating plate 210, so that the flow channel in the temperature regulating plate 210 is connected to the third channel 14 and the fourth channel 15 of the connector 116, the flow channel in the temperature regulating plate 210 can be connected to the first collecting cavity 1110 and the second collecting cavity 1111 of the collector 110, so that the temperature regulating medium of the collector 110 can flow into the flow channel of the temperature regulating plate 210, or the temperature regulating medium in the flow channel of the temperature regulating plate 210 can flow into the collector 110.

[0108] Compared with the related technology in which the current collector 110 is directly welded to the temperature regulating plate 210, the current collector 110 of the current collection structure 11 provided in this application embodiment is first connected to the connector 116, and then the connector 116 is connected to the temperature regulating plate 210. The current collector 110 does not need to be directly welded to the temperature regulating plate 210. The current collector 110 and the temperature regulating plate 210 can be made of different materials, which is beneficial to reducing the production cost of the current collector 110, and thus reducing the cost of the current collection structure 11.

[0109] In particular, when the temperature regulating plate 210 is made of a metal with high thermal conductivity, the material of the current collector 110 can be plastic or other low-cost materials, making the cost of the current collector 110 of the current collection structure 11 even lower.

[0110] See Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The first end 1161 of the connector 116 can be inserted into the opening 1120 of the collector 110, so that the first end 1161 is connected to the end of the collector 110 with the opening 1120, making it easier to connect the first end 1161 of the connector 116 to the end of the collector 110 with the opening 1120. The first limiting part 1121 can protrude from the inner circumferential surface of the collector cavity, and the first abutting part 1164 can protrude from the outer circumferential surface of the connector 116, so that the first limiting part 1121 can stably abut against the first abutting part 1164, thereby restricting the movement of the connector 116 relative to the collector 110 along the first direction X.

[0111] The first abutting portion 1164 can be extended circumferentially along the opening 1120 of the collector 110 to increase the length of the first abutting portion 1164 extending circumferentially in the opening 1120 of the collector 110, so that the first limiting portion 1121 can abut more stably with the first abutting portion 1164.

[0112] See Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 This allows the first limiting portion 1121 to extend circumferentially along the opening 1120, thereby increasing the length of the first limiting portion 1121 extending circumferentially in the opening 1120 of the current collector 110, so that the first limiting portion 1121 can more stably abut against the first abutting portion 1164.

[0113] It should be noted that both the first limiting part 1121 and the first abutting part 1164 can extend along the circumference of the opening 1120, or only the first limiting part 1121 or the first abutting part 1164 can extend along the circumference of the opening 1120. Of course, the former can make the abutment of the first limiting part 1121 and the first abutting part 1164 more stable.

[0114] As a variation, the end of the current collector 110 with the opening 1120 can be inserted into the channel of the connector 116, so that the first end 1161 is inserted into the end of the current collector 110 with the opening 1120, making it easier to insert the first end 1161 of the connector 116 into the end of the current collector 110 with the opening 1120. Specifically, the first limiting part 1121 can protrude from the outer peripheral surface of the current collector 110, and the first abutting part 1164 can protrude from the inner peripheral surface of the channel, so that the first limiting part 1121 can stably abut against the first abutting part 1164, thereby restricting the movement of the connector 116 relative to the current collector 110 along the second direction Y.

[0115] For example, see Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The abutment structure 1163 further includes a second abutment portion 1165, which is disposed on the connector 116. The second abutment portion 1165 is located on one side of the first limiting portion 1121 along the second direction Y. The first limiting portion 1121 abuts against the second abutment portion 1165 to restrict the movement of the connector 116 relative to the collector along the second direction Y. Thus, by cooperating with the first abutment portion 1164 and the second abutment portion 1165 and the first limiting portion 1121, the relative movement of the collector and the connector 116 in the second direction Y can be limited, making the connection between the collector and the connector 116 more stable.

[0116] Continue to refer to Figure 4 The limiting structure 112 also includes a second limiting part 1122, which may also be on the current collector 110. The first abutting part 1164 is located on one side of the second limiting part 1122 along the second direction Y. The second limiting part 1122 abuts against the first abutting part 1164 to restrict the movement of the connecting member 116 relative to the current collector along the second direction Y. Thus, by cooperating with the first limiting part 1121 and the second limiting part 1122 and the first abutting part 1164, the relative movement of the current collector and the connecting member 116 in the second direction Y can be limited, making the connection between the current collector and the connecting member 116 more stable.

[0117] The connector 116 is a pipe structure extending along the second direction Y. The first abutting portion 1164 abuts against the second limiting portion 1122 on one side along the second direction Y. The first limiting portion 1121 abuts against the first abutting portion 1164 on one side along the second direction Y. The second abutting portion 1165 abuts against the first limiting portion 1121 on one side along the second direction Y. The second abutting portion 1165 protrudes from the outer periphery of the connector 116. The second abutting portion 1165 extends circumferentially along the opening 1120. The second limiting portion 1122 is provided on the inner circumferential surface of the collecting cavity. The second limiting portion 1122 extends circumferentially along the opening 1120. The first abutting portion 1164 extends circumferentially along the opening 1120 in a ring structure. The second abutting portion 1165 extends circumferentially along the opening 1120 in a ring structure. The first limiting portion 1121 extends circumferentially along the opening 1120 in a ring structure. The second limiting part 1122 extends circumferentially along the opening 1120 in a ring structure.

[0118] In some embodiments, the manifold and the connector 116 can be injection molded together, thereby making the processing of the manifold and the connector 116 more convenient and the connection between the manifold and the connector 116 more stable.

[0119] Alternatively, the current collector can be bonded to the connector 116, making the connection between the current collector and the connector 116 more convenient.

[0120] In some embodiments, see Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The first connector 113 includes two first sub-connectors 1133, which are movably mounted on one side of the current collector 110 along the first direction X. The two first sub-connectors 1133 are arranged side-by-side along the height direction Z of the current collector 110. One of the first sub-connectors 1133 has a first sub-channel 1130, and the other first sub-connector 1133 has a second sub-channel 1131.

[0121] Correspondingly, the second connector 115 includes two second sub-connectors 1157, which are located on the side of the current collector 110 away from the first connector 113. One of the second sub-connectors 1157 has a third sub-channel 1151, and the other second sub-connector 1157 has a fourth sub-channel 1152. When adjacent current collector structures 11 are connected, the two first sub-connectors 1133 are aligned with the two second sub-connectors 1157, and the first sub-connectors 1133 engage with the corresponding second sub-connectors 1157.

[0122] By making the first sub-connector 1133 movable relative to the current collector 110, when connecting the first sub-connector 113 to the second sub-connector 115 of the adjacent current collector structure 11, and connecting the first sub-channel 1130 to the third sub-connection of the adjacent current collector structure 11, and the second sub-channel 1131 to the first filament of the adjacent current collector structure 11, the position of the first sub-connector 1133 can be adaptively adjusted according to the relative position of the first sub-connector 1133 and the second sub-connector 1157 of the adjacent current collector structure 11, so that the first sub-connector 1133 can be accurately connected to the second sub-connector 1157 of the adjacent current collector structure 11, reducing the assembly accuracy requirements of the first sub-connector 1133 and the second sub-connector 1157 of the adjacent current collector structure 11, and improving the assembly efficiency of the diversion assembly 10.

[0123] In some embodiments, see Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The first sub-connector 1133 can be inserted into the second sub-connector 1157 of the adjacent current collection structure 11, so that the first sub-connector 1133 is connected to the second sub-connector 1157 of the adjacent current collection structure 11.

[0124] Multiple annular seals 1142 can be fitted onto the outer circumferential surface of the first sub-connector 1133. When the first sub-connector 1133 is inserted into the second sub-connector 1157 of the adjacent manifold structure 11, the annular seals 1142 abut against the inner circumferential surface of the channel in the second sub-connector 1157 of the adjacent manifold structure 11, so as to form a sealing structure between the outer circumferential surface of the first sub-connector 1133 and the inner circumferential surface of the channel in the second sub-connector 1157 of the adjacent manifold structure 11, thereby preventing the temperature regulating medium from leaking out from the gap between the outer circumferential surface of the first sub-connector 1133 and the second sub-connector 1157 of the adjacent manifold structure 11.

[0125] Of course, the second sub-connector 1157 of the adjacent current collection structure 11 can also be inserted into the first sub-connector 1133 of the current collection structure 11 so that the first connector 113 is connected to the second connector 115 of the adjacent current collection structure 11.

[0126] In some embodiments, see Figure 3, Figure 4 , Figure 5 , Figure 6 and Figure 7 The first sub-connector 1133 can include a guide section 1137, which extends from the end of the first sub-connector 1133 away from the current collector 110 toward the current collector 110. The outer diameter of the guide section 1137 gradually decreases in the direction away from the current collector 110. The guide section 1137 is inserted into the adjacent second connector 115. Thus, when the first sub-connector 1133 is inserted into the second connector 115 of the adjacent current collector structure 11, the outer circumferential surface of the guide section 1137 can guide the first sub-connector 1133 to be connected to the second sub-connector 1157 of the adjacent current collector structure 11, thereby improving the assembly efficiency of the two current collector structures 11.

[0127] The first sub-connector 1133 can be moved radially relative to the current collector 110 in the first channel 12. The amount of radial movement of the first sub-connector 1133 relative to the current collector 110 in the first channel 12 is λ. The difference between the maximum and minimum circumscribed radius of the guide section 1137 is X1. X1 can be ≥ 0.5λ. This further improves the guiding effect of the guide section 1137, allowing the first sub-connector 1133 to be inserted more quickly and accurately into the second sub-connector 1157 of the adjacent current collector structure 11.

[0128] X1 can be 0.6λ, 0.68λ, 0.72λ, 0.8λ, 0.9λ, etc., and can be determined according to the size and shape of the first sub-connector 1133, the first sub-channel 1130, and the second sub-channel 1131.

[0129] Alternatively, the third sub-channel 1151 and the fourth sub-channel 1152 of the second connector 115 can both include guide hole sections 1153. These guide hole sections 1153 extend from the end of the second connector 115 away from the collector 110 towards the collector 110, and the inner diameter of the inscribed circle of the guide hole section 1153 gradually decreases in the direction approaching the collector 110. Therefore, when the first sub-connector 1133 is inserted into the second sub-connector 1157 of the adjacent collector structure 11 to connect with the second sub-connector 1157 of the adjacent collector structure 11, the inner circumferential surface of the guide hole section 1153 can provide guidance, allowing the first sub-connector 1133 to be quickly and accurately inserted into the second sub-connector 1157 of the adjacent collector structure 11, thus improving the connection efficiency of the two collector structures 11.

[0130] like Figure 5As shown, the difference between the maximum and minimum inscribed circle radii of the guide hole segment 1153 is X2, where X2-0.5λ ≥ 0.5 mm. This further improves the guiding effect of the guide hole segment 1153, allowing the first sub-connector 1133 to be inserted more quickly and accurately into the second sub-connector 1157 of the adjacent current collection structure 11. The value of X2-0.5λ can be 0.55 mm, 0.62 mm, 0.68 mm, 0.72 mm, 0.8 mm, 0.9 mm, etc., specifically determined according to the size and shape of the first connector 113 and the first through hole.

[0131] It should be noted that the first sub-connector 1133 may include a guide section 1137, and the third sub-channel 1151 or the fourth sub-channel 1152 may include a guide hole section 1153. Alternatively, only the first sub-connector 1133 may include a guide section 1137, or only the third sub-channel 1151 or the fourth sub-channel 1152 may include a guide hole section 1153. Of course, the former allows the first sub-connector 1133 to be inserted more quickly and accurately into the second sub-connector 1157 of the adjacent current collection structure 11.

[0132] In some embodiments, such as Figure 3 , Figure 5 and Figure 6 As shown, a connecting structure 1112 can be provided on one side of the current collector 110 along the first direction X. The first connector 113 includes a connecting portion 1132, which is movably connected to the connecting structure 1112, so that the first sub-connector 1133 is movably installed on one side of the current collector 110 along the first direction X. A sealing ring 1141 is provided between the first sub-connector 1133 and the current collector 110. The sealing ring 1141 surrounds the first sub-connector 1133, and the first sub-connector 1133 and the current collector 110 clamp the sealing ring 1141 to form a sealing and protective structure. Thus, while the position of the first sub-connector 1133 relative to the current collector 110 is adjustable, the temperature regulating medium in the first channel 12 and the second channel 13 will not leak out from the gap between the first connector 113 and the current collector 110.

[0133] In some embodiments, the first sub-connector 1133 may be moved radially relative to the connecting structure 1112 in the first channel 12 or the second channel 13. When connecting the first sub-connector 1133 to the second sub-connector 1157 of the adjacent current collection structure 11, if the first sub-connector 1133 and the second sub-connector 1157 of the adjacent current collection structure 11 are misaligned radially in the first channel 12, the first sub-connector 1133 can be aligned with the second sub-connector 1157 of the adjacent current collection structure 11 by moving the first sub-connector 1133 a certain distance radially relative to the connecting structure 1112 in the first channel 12, so that the first sub-connector 1133 and the second sub-connector 1157 of the adjacent current collection structure 11 can be quickly and accurately connected together.

[0134] Alternatively, the first sub-connector 1133 can be oscillated radially relative to the connecting structure 1112 in the first channel 12 or the second channel 13. When connecting the first sub-connector 1133 to the second sub-connector 1157 of the adjacent collector structure 11, if the first sub-connector 1133 and the second sub-connector 1157 of the adjacent collector structure 11 are tilted at a certain angle in the radial direction of the first channel 12, the first sub-connector 1133 and the second sub-connector 1157 of the adjacent collector structure 11 can be aligned by oscillating the first sub-connector 1133 relative to the connecting structure 1112 in the radial direction of the first channel 12, so that the first sub-connector 1133 and the second sub-connector 1157 of the adjacent collector structure 11 can be quickly and accurately connected together.

[0135] Furthermore, the first sub-connector 1133 can be moved axially relative to the connecting structure 1112 in the first channel 12 or the second channel 13. When connecting the first sub-connector 1133 to the second sub-connector 1157 of the adjacent collector structure 11, if the distance between the first sub-connector 1133 and the second sub-connector 1157 of the adjacent collector structure 11 in the first channel 12 is relatively large, the first sub-connector 1133 can be quickly and accurately connected to the second sub-connector 1157 of the adjacent collector structure 11 by moving the first sub-connector 1133 relative to the connecting structure 1112 in the first channel 12 a certain distance.

[0136] It should be noted that the first sub-connector 1133 can be moved relative to the connection structure 1112 in one or more of the above three modes of operation, depending on the accuracy requirements of the connection between the first sub-connector 1133 and the second sub-connector 1157 of the adjacent current collection structure 11.

[0137] In some embodiments, see Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7The connecting structure 1112 may include a limiting member 1113 connected to the collector 110. The limiting member 1113 is located on the side of the connecting portion 1132 away from the collector 110. The limiting member 1113 abuts against the side of the connecting portion 1132 away from the collector 110, so that the connecting portion 1132 and the collector 110 clamp the sealing ring 1141.

[0138] Therefore, the limiting member 1113 can apply a thrust to the connecting part 1132, causing the connecting part 1132 to clamp the sealing ring 1141 with the collector 110. Moreover, the connecting part 1132 can also move and swing radially relative to the connecting structure 1112 in the first sub-channel 1130 or the second sub-channel 1131 of the first sub-joint 1133, and can also move a certain distance axially along the first sub-channel 1130 or the second sub-channel 1131, so that the first sub-joint 1133 can move and swing radially relative to the connecting structure 1112 in the first sub-channel 1130 or the second sub-channel 1131, and can also move axially along the first sub-channel 1130 or the second sub-channel 1131.

[0139] In some embodiments, see Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The connecting structure 1112 may also include a connecting protrusion 1115 protruding from the current collecting structure 11 along the first direction X. The connecting protrusion 1115 encloses two grooves 1116, and the bottom surfaces of the two grooves 1116 are respectively provided with a first interface 1117 and a second interface 1118. The first interface 1117 communicates with the first current collecting cavity 1110, and the second interface 1118 communicates with the second current collecting cavity 1111. The connecting portion 1132 of the two first sub-connectors 1133 At least partially accommodated within the corresponding groove 1116, the first sub-channel 1130 communicates with the first interface 1117, the second sub-channel 1131 communicates with the second interface 1118, and the limiting member 1113 is connected to the connecting protrusion 1115 to make the connection between the limiting member 1113 and the collector 110 more convenient. The limiting member 1113 can be located on the side of the connecting portion 1132 of the first sub-connector 1133 away from the collector 110 to stably limit the connecting portion 1132.

[0140] The limiting member 1113 can be welded or bonded to the connecting protrusion 1115 to increase the connection strength between the limiting member 1113 and the connecting protrusion 1115 and simplify the structure. Of course, the limiting member 1113 can also be connected to the connecting protrusion 1115 by means of screw fixing, snap-fit, etc.

[0141] Specifically, the connecting protrusion 1115 is an annular protrusion surrounding the first sub-connector 1133. The connecting portion 1132 is accommodated within the groove 1116 of the connecting protrusion 1115. Axially, in the first sub-channel 1130 or the second sub-channel 1131 of the first sub-connector 1133, the thickness of the connecting portion 1132 is less than the depth of the groove 1116. The limiting member 1113 is an annular plate-like structure surrounding the first sub-connector 1133. The outer edge of the limiting member 1113 is connected to the end of the connecting protrusion 1115 away from the current collector 110, and covers the groove 1116 formed by the connecting protrusion 1115.

[0142] In some embodiments, the limiting member 1113 may be disposed around the first sub-connector 1133. This allows the limiting member 1113 to have a larger area to abut against the surface of the connecting portion 1132 on the side opposite to the current collector 110, making the limiting member 1113 more stably abut against the first sub-connector 1133.

[0143] The limiting member 1113 has a clearance hole 1114 for the first sub-connector 1133 to pass through. The first sub-connector 1133 includes a mating section 1136 located within the clearance hole 1114, the inner diameter of the clearance hole 1114 being larger than the outer diameter of the mating section 1136. Thus, the clearance hole 1114 provides space for the mating section 1136 to move and swing radially in the first sub-channel 1130 or the second sub-channel 1131, thereby allowing the first sub-connector 1133 to move and swing radially relative to the connecting structure 1112 in the first sub-channel 1130 or the second sub-channel 1131.

[0144] In some embodiments, see Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 This allows the outer diameter of the connecting portion 1132 to be larger than the inner diameter of the clearance hole 1114. As a result, the limiting member 1113 can more stably abut against the side of the connecting portion 1132 away from the collector 110, preventing the connecting portion 1132 from coming out of the clearance hole 1114.

[0145] In some embodiments, the connecting portion 1132 can be located at one end of the first sub-connector 1133 near the collector 110, and the first sub-channel 1130 or the second sub-channel 1131 passes through the connecting portion 1132; the sealing ring 1141 is located between the connecting portion 1132 and the collector 110, and the connecting portion 1132 and the collector 110 clamp the sealing ring 1141. By clamping the sealing ring 1141 between the connecting portion 1132 and the collector 110, the gap between the first connector 113 and the collector 110 can be effectively sealed.

[0146] In some embodiments, see Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 This allows the compression ratio of the sealing ring 1141 to be greater than or equal to 8% and less than or equal to 42%, enabling the sealing ring 1141 to have a high sealing effect and sealing stability.

[0147] The compression ratio of the sealing ring 1141 can be greater than or equal to 15% and less than or equal to 30% to improve the sealing effect and extend the sealing time. Specifically, the compression ratio of the sealing ring 1141 can be 18%, 20%, 23%, 26%, 29%, etc.

[0148] In some embodiments, see Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 A first engaging portion 1123 can be provided on the side of the limiting member 1113 facing away from the current collector 110. The second connector 115 has two second engaging portions 1154. A second engaging portion 1154 is provided on the outer wall of the third sub-channel 1151 and the outer wall of the fourth sub-channel 1152. The second engaging portions 1154 engage with the first engaging portion 1123 of the adjacent current collector structure 11 to limit the relative movement distance of the two current collector structures 11 in the first direction X. This makes the connection between the first sub-connector 1133 and the second sub-connector 1157 of the adjacent current collector structure 11 more stable, reducing the risk of the two current collector structures 11 moving away from each other in the first direction X and separating.

[0149] The first latching portion 1123 may include a plurality of first sub-latching portions 1124, which are spaced apart circumferentially along the first sub-connector 1133. The second latching portion 1154 includes a plurality of second sub-latching portions 1155, which are spaced apart circumferentially along the corresponding third sub-channel 1151 or fourth sub-channel 1152. The first sub-latching portions 1124 are located between the second sub-latching portions 1155, and the second sub-latching portions 1155 abut against the first sub-latching portions 1124 to limit the relative movement distance of the two current collection structures 11 in the first direction X and the radial direction of the first channel 12.

[0150] The first locking portion 1123 includes a first protrusion 1125 extending from the limiting member 1113 along a first direction X, and a first sub-locking portion 1124 connected to one end of the first protrusion 1125 along the first direction X. The second locking portion 1154 includes a second protrusion 1156 extending from the second connector 115 or the current collector 110 in a direction away from the first connector 113, and the second sub-locking portion 1155 is located at the end of the second protrusion 1156 away from the current collector 110.

[0151] In some embodiments, see Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 A connecting portion 1132 is provided at one end of the first sub-connector 1133 near the collector 110. A sealing ring 1141 is located between the connecting portion 1132 and the collector 110, with the connecting portion 1132 and the collector 110 clamping the sealing ring 1141. This design aims to enhance the stability and sealing performance of the diversion assembly 10. The first sub-connector 1133 clamps and fixes the sealing ring 1141 with the collector 110, reducing the need for fixing the sealing ring 1141 and improving the structural compactness of the collector structure 11. This also simplifies the installation and replacement of the sealing ring 1141, reducing maintenance costs and time.

[0152] In some embodiments, see Figure 15 , Figure 16 and Figure 17 One of the multiple flow collection structures 11 further includes a third connector 117. The third connector 117 is disposed on the side of the flow collector 110 opposite to the opening 1120. The third connector 117 has a fifth channel 1171, which communicates with the first flow collection chamber 1110 or the second flow collection chamber 1111. The third connector 117 is used to connect to the inlet pipe 25 or the outlet pipe 26. The third connector 117 is inserted and fixed to the inlet pipe 25 or the outlet pipe 26, which facilitates the connection of the flow distribution assembly 10 to the inlet pipe 25 and the outlet pipe 26.

[0153] Specifically, when the third connector 117 on the manifold structure 11 is used to connect with the inlet pipe 25, the fifth channel 1171 communicates with the first manifold chamber 1110. When the fourth connector on the manifold structure is used to connect with the outlet pipe 26, the fifth channel 1171 communicates with the second manifold chamber 1111. The end of the inlet pipe 25 or the outlet pipe 26 is inserted into the fifth channel 1171 of the third connector 117. The inner surface of the fifth channel 1171 of the third connector 117 is provided with a sealing groove, and a sealing ring is installed in the sealing groove. The inlet pipe 25 or the outlet pipe 26 is sealed to the third connector 117 through the sealing ring, ensuring the reliability of the liquid inlet or outlet of the diversion assembly 10.

[0154] In some embodiments, see Figure 15, Figure 16 and Figure 17 The current collector 110 has a boss 1172 on the side near the third connector 117. The boss 1172 extends radially along the fifth channel 1171. The boss 1172 extends from one side of the fifth channel 1171 into the fifth channel 1171. The boss 1172 is partially located on the extension path of the fifth channel 1171.

[0155] Understandably, by providing a boss 1172 on the side of the current collector 110 near the third connector 117, with part of the boss 1172 located on the extension path of the fifth channel 1171, the temperature regulating medium flowing out of or into the fifth channel 1171 is dispersed by the impact of the boss 1172, thereby achieving a flow limiting function and reducing the flow resistance pressure drop in the diversion assembly 10.

[0156] In some embodiments, see Figure 15 , Figure 16 and Figure 17 The boss 1172 has a through hole 1173, which is connected to the fifth channel 1171. The through hole 1173 is a "U"-shaped through hole 1173, with the opening 1120 facing the axis of the fifth channel 1171. The temperature regulating medium flowing out of or into the fifth channel 1171 is impacted and dispersed by the boss 1172 and passes through the through hole 1173. The boss 1172 not only serves to divert the flow but also further reduces the flow resistance.

[0157] The second aspect, see [link / reference]. Figure 9 and Figure 10 This application also provides a temperature control system 21, which includes an inlet pipe 25, an outlet pipe 26, multiple temperature control plates 210, and the aforementioned diversion assembly 10. The inlet pipe 25 is connected to the inlet end 1174, and the outlet pipe 26 is connected to the outlet end 1175. The diversion assembly 10 is installed along the second direction Y on one side of the temperature control plate 210, and the flow collecting structure 11 is inserted into the end of the corresponding temperature control plate 210. The specific structure of the diversion assembly 10 is as described in the above embodiments. Since this temperature control system 21 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.

[0158] In some implementations, see Figure 9 and Figure 10 The temperature control system 21 also includes a BDU liquid cooling plate 211. Along the height direction Z of the temperature control plate 210, the BDU liquid cooling plate 211 is located on one side of the temperature control plate 210. The BDU liquid cooling plate 211 is connected to the inlet pipe 25 and the outlet pipe 26.

[0159] In this embodiment, the BDU liquid cooling plate 211 and the diversion assembly 10 share the inlet pipe 25 and the outlet pipe 26, reducing the pipeline layout and improving space utilization.

[0160] In some embodiments, the temperature control system 21 includes two shunt components 10, which are disposed at the ends of corresponding battery modules 22. The liquid inlet ends 1174 of the two shunt components 10 and the liquid inlet end 1174 of the BDU liquid cooling plate 211 are connected to the liquid inlet pipe 25 via a pipe connector 27. The liquid outlet ends 1175 of the two shunt components 10 and the liquid outlet end 1175 of the BDU liquid cooling plate 211 are connected to the liquid outlet pipe 26 via a pipe connector 27. The pipe connector 27 can be a four-way connector 27, facilitating the assembly of the shunt components 10, the BDU liquid cooling plate 211, and the liquid inlet pipe 25 or the liquid outlet pipe 26, improving the assembly effect of the temperature control system 21 and reducing production costs.

[0161] See Figure 1 This application also provides a battery pack 20, which includes a temperature regulation system 21. The specific structure of the temperature regulation system 21 is as described in the above embodiments. Since the battery pack 20 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.

[0162] In some embodiments, see Figure 1 The battery pack 20 includes multiple stacked battery modules 22, each battery module 22 includes multiple battery packs 220, and each battery module 22 has a shunt assembly 10 at its end. A temperature regulating plate 210 is installed on both sides of the battery packs 220 of the corresponding battery module 22.

[0163] In this embodiment, a temperature regulating medium is delivered to the temperature regulating plate 210 corresponding to each battery module 22 through multiple shunt components 10, thereby achieving temperature regulation of the battery pack 20, and the battery pack 20 has a compact structure.

[0164] For example, the battery pack 20 includes two battery modules 22 stacked along the height direction Z of the battery pack 20, and each battery module 22 includes multiple battery packs 220. The corresponding temperature regulation system 21 includes two shunt components 10, which are disposed at the ends of the battery modules 22 and are located on the same side of the battery pack 20. The temperature regulating plate 210 connected to each current collector structure 11 in the shunt component 10 is disposed on both sides of the battery pack 220. The BDU liquid cooling plate is installed on one side of the battery pack 20 along the height direction Z. The liquid inlet end 1174 of the BDU liquid cooling plate 211, the liquid inlet ends 1174 of the two shunt components 10 and the liquid inlet pipe 25 are assembled through a four-way pipe connector 27, and the liquid outlet end 1175 of the BDU liquid cooling plate 211, the liquid outlet end 1175 of the two shunt components 10 and the liquid outlet pipe 26 are assembled through a four-way pipe connector 27.

[0165] In this embodiment, the inlet pipe 25 is connected to the inlet ends 1174 of multiple flow dividers 10 via pipe connectors 27, ensuring that the temperature regulating medium can smoothly enter each flow divider 10 for processing. The outlet pipe 26 is also connected to the outlet ends 1175 of multiple flow dividers 10 via pipe connectors 27, ensuring that the processed temperature regulating medium can be quickly discharged, thereby ensuring the continuity and stability of the system. The assembly method of the inlet pipe 25, outlet pipe 26, pipe connectors 27, and flow dividers 10 is simple, improving the assembly efficiency of the battery pack 20.
