[0050] The embodiments of the utility model provide a flow distribution component, a flow distribution assembly and a battery rack, wherein the flow distribution component and / or the flow distribution assembly can be applied to the battery rack, and it should be understood that the battery rack may include the flow distribution component and / or the flow distribution assembly. It should also be understood that the flow distribution component, the flow distribution assembly and the battery rack defined in the embodiments of the present application can all be applied to immersion scenarios, such as the flow distribution component, the flow distribution assembly and the battery rack can all be applied in the testing of battery devices. For those skilled in the art, the flow distribution component and the flow distribution assembly in the embodiments of the present application are not limited to immersion scenarios, and can also be applied to other fluid scenarios.

[0051] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use. All other embodiments obtained by those skilled in the art without creative work based on the embodiments in the present application belong to the scope of protection of the present application.

[0052] Reference to "embodiment" or "implementation" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment or implementation may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0053] like Figures 1 to 5 As shown, the battery rack 10 includes a rack body 200 and a plurality of flow distribution components 100, and the plurality of flow distribution components 100 are detachably connected to the rack body 200. Thus, the number of flow distribution components 100 installed on the rack body 200 and the installation position can be selected according to actual needs. Figure 1 The schematic diagram shows the installation relationship between a flow distribution component 100 and a frame 200. Figure 1 For an exemplary view, Figure 1 The number of flow distribution components 100 shown does not constitute a limitation on the number of flow distribution components 100 in the embodiment of the present application.

[0054] It should be noted that in the battery rack of the relevant battery device, the battery rack has too many diversion holes, and the diversion holes directly opened in the battery rack are used to divert the medium. In the relevant technology, each diversion hole of the battery rack has roughly the same flow rate and flow direction. However, in actual applications, the battery module arrangement method, boundary convection and other methods of the battery device lead to inconsistent temperatures of the battery modules placed in each immersion battery compartment.

[0055] It should also be noted that in the immersion scene, the flow field of the immersion scene needs to adjust the structure of the battery rack according to different media, resulting in high costs. In addition, the flow allocation of the immersion scene test prototype cannot be flexibly adjusted, resulting in high investment costs and long R&D cycles for the immersion scene test prototype.

[0056] In the embodiment of the present application, the frame 200 and multiple flow distribution components 100 are detachably connected, which can increase the flexibility of the deployment of the flow distribution components 100 to a certain extent. For example, in the first case, the frame 200 needs to be equipped with N flow distribution components 100, and in the second case, the frame 200 needs to be equipped with M flow distribution components 100, where M and N are both integers greater than zero, and M is greater than N. It should be understood that there may be other situations, which are not illustrated one by one here. Therefore, the battery rack 10 of the embodiment of the present application can improve flexibility to a certain extent during the deployment of the flow distribution components 100 of the immersion scene test prototype, and thus can reduce costs and shorten the research and development cycle to a certain extent. That is, in the embodiment of the present application, since multiple flow distribution components 100 can be detachably connected to the frame 200, the embodiment of the present application can set the number of flow distribution components 100 according to actual needs.

[0057] Exemplarily, the outer contours of the various flow distribution components 100 are substantially consistent, which is conducive to processing and molding the flow distribution components 100, such as using an injection molding process to mold a plurality of flow distribution components 100.

[0058] Among them, each flow distribution component 100 can distribute the medium, or the flow distribution component 100 is configured to distribute the medium. Specifically, each flow distribution component 100 can distribute liquid. It can also be understood that each flow distribution component 100 can transmit liquid.

[0059] Exemplarily, at least two of the multiple flow distribution components 100 distribute the medium at different flow rates. It should be understood that at least two flow distribution components 100 distribute the medium at different flow rates, which can also be understood as at least two flow distribution components having different medium flow rate distribution functions. Therefore, the multiple flow distribution components 100 in the embodiment of the present application can flexibly allocate flow distribution components 100 with different medium flow rate functions according to different needs, such as flexibly allocate flow distribution components 100 with different medium flow rate functions according to different media. In practical applications, when it is determined that the temperature at a predetermined position of the battery device is too high, a flow distribution component 100 with a larger medium flow rate can be allocated, so that the flow distribution component 100 provides a larger medium flow rate to the predetermined position, and the medium flow rate at the preset position can be increased to accelerate the reduction of the temperature at the predetermined position. Thereby, the temperature uniformity of the battery device during the charging and discharging process is improved.

[0060] That is, the multiple flow distribution components 100 in the embodiment of the present application can flexibly allocate different flow distribution components 100 according to different needs. For example, when the temperature at a predetermined position is high, a flow distribution component 100 with a larger flow rate of the distribution medium can be used to distribute the medium, which can improve the temperature uniformity of the battery device during the charging and discharging process.

[0061] In addition, the embodiment of the present application can allocate the flow distribution component 100 with different medium flow rate functions according to the needs, so the frame 200 of the embodiment of the present application can be applied to different needs, and the flow distribution component 100 installed on the frame 200 is determined according to different needs, so compared with the related art that one frame is applicable to one need, or one frame is applicable to one medium in the related art, or one frame is applicable to one medium flow rate in the related art, the embodiment of the present application can greatly reduce the cost. Moreover, the flow allocation of the immersion scene test prototype can be further flexibly adjusted, which can further reduce the investment cost of the immersion scene test prototype and shorten the research and development cycle.

[0062] Therefore, the outer contours of the various flow distribution components 100 in the embodiment of the present application are roughly the same, and at least two flow distribution components 100 distribute different flow rates of the medium. In practical applications, the flow distribution components 100 of required specifications can be installed at the preset position of the frame 200 according to actual needs. In the actual test process, it is convenient to adjust the flow distribution components 100 of different specifications for debugging, and there will be no installation obstacles.

[0063] The battery rack 10 has a length direction D1 and a width direction D2 , and the length direction D1 and the width direction D2 are substantially perpendicular to each other.

[0064] The frame 200 is provided with a flow guide channel 201, a plurality of battery compartments 202 and a plurality of mounting holes 203. The plurality of battery compartments 202 are connected to the plurality of mounting holes 203, and one battery compartment 202 is connected to at least one mounting hole 203. The embodiment of the present application takes one battery compartment 202 and one mounting hole 203 as an example. The flow guide channel 201 is connected to the plurality of mounting holes 203, and the plurality of mounting holes 203 are connected to the flow guide channel 201 and the plurality of battery compartments 202. It should be understood that when the mounting hole 203 is not equipped with a fluid distribution component 100, the flow guide channel 201 and the plurality of battery compartments 202 are directly connected through the plurality of mounting holes 203.

[0065] The multiple battery compartments 202 can be divided into two groups, one of which is located on one side of the guide channel 203, and the other is located on the other side of the guide channel 203. One group of battery compartments 202, the guide channel 203, and the other group of battery compartments 202 are arranged in sequence in the width direction D2 of the battery rack 10. There are multiple battery compartments 202 on both sides of the guide channel 203, and the multiple battery compartments 202 on the same side of the guide channel 203 are arranged in sequence along the length direction D1 of the battery rack 10.

[0066] Continue reading Figures 1 to 4The frame 200 includes a guide plate 210, a bottom plate 220, a side plate 230 and a plurality of partitions 240. The guide plate 210, the side plate 230 and the partitions 240 are all connected to the same surface of the bottom plate 220 to define a plurality of battery compartments 202. The guide plate 210, the side plate 230 and the bottom plate 220 together define a guide channel 201. A plurality of mounting holes 203 are all provided on the guide plate 210.

[0067] Exemplarily, the side plate 230 is connected to the periphery of the bottom plate 220, and the plurality of partitions 240 and the guide plate 210 are surrounded by the side plate 230. Exemplarily, the side plate 230 can be surrounded to form a rectangular space. One end of the plurality of partitions 240 is connected to the inner surface of the side plate 230, and the other end of the plurality of partitions 240 is connected to the guide plate 210.

[0068] Exemplarily, there are two guide plates 210, which are spaced apart and separated by the guide channel 201. One end of the two guide plates 210 is connected to the inner surface of one side of the side plate 230, and the other end of the two guide plates 210 is connected to the inner surface of the other side of the side plate 230.

[0069] The plurality of partitions 240 can be defined as two groups, one group of partitions 240 corresponding to one group of battery compartments 202. There is one battery compartment 202 between two adjacent partitions 240 in one group of partitions 240, and two of the partitions 240 in one group of partitions 240 and two sides of the side plate 230 form two battery compartments 202.

[0070] Each guide plate 210 is provided with a plurality of mounting holes 201, and one mounting hole 201 can directly connect one battery compartment 202 and the guide channel 201. Exemplarily, the number of mounting holes 201 provided on the two guide plates 210 is the same. Exemplarily, the positions of the mounting holes 201 provided on the two guide plates 210 are the same. It should be noted that the positions and the number of the mounting holes 201 provided on each guide plate 210 can be set according to actual needs.

[0071] Exemplarily, the two guide plates 210 are substantially flush with one another at surfaces away from the bottom plate 220 .

[0072] Exemplarily, the height of the two guide plates 210 is not higher than the height of the side plate 230. For example, the side of the two guide plates 210 away from the bottom plate 220 is roughly flush with the side of the side plate 230 away from the bottom plate 220, or the side of the two guide plates 210 away from the bottom plate 220 is slightly lower than the side plate 230, or the vertical distance between the two guide plates 210 and the bottom plate 220 is not greater than the vertical distance between the side plate 230 and the bottom plate 220.

[0073] Continue reading Figures 1 to 4The frame 200 is further provided with a flow inlet 204 , which penetrates the side plate 230 and is connected with the flow guide channel 201 .

[0074] Continue reading Figures 1 to 4 The frame 200 further includes a joint 250 , which is connected to the side plate 230 and is connected to the outer surface of the side plate 230 . The flow inlet 204 penetrates the joint 250 and the side plate 230 , and is communicated with the flow guide channel 201 .

[0075] Any battery compartment 202 can accommodate a battery cell, or a battery element.

[0076] A plurality of flow distribution components 100 can be installed in the mounting holes 203. When the plurality of flow distribution components 100 are connected to the frame 200, the plurality of flow distribution components 100 are installed in the plurality of mounting holes 203, and one flow distribution component 100 is installed in one mounting hole 203.

[0077] Any flow distribution component 100 is used to distribute the medium placed in the diversion channel 201 to the battery compartment 202, and at least two flow distribution components 100 can distribute the medium placed in the diversion channel 201 to the battery compartment 202 at different flow rates. Exemplarily, multiple flow distribution components 100 are each provided with at least one diversion hole 130, and the number of diversion holes 130 in each flow distribution component 100 is the same, and any flow distribution component 100 is used to distribute the medium placed in the diversion channel 201 to the battery compartment 202 connected thereto through its diversion hole 130. Or it can be understood that the flow distribution component 100 is configured to distribute the medium through its diversion hole 130, such as distributing it to the battery compartment 202 connected thereto, or distributing it to the corresponding connected battery compartment 202.

[0078] Exemplarily, the guide holes 130 of at least two flow distribution components 100 are of different sizes. For example, the plurality of flow distribution components 100 include one or more first flow distribution components and one or more second flow distribution components, and the difference between the first flow distribution component and the second flow distribution component is that the guide holes of the two are of different sizes, such as the guide holes of the first flow distribution component are larger than the guide holes of the second flow distribution component. When both the first flow distribution component and the second flow distribution component distribute the medium, the capacity of the medium distributed by the first flow distribution component is greater than the capacity of the medium distributed by the second flow distribution component, or the flow rate of the medium distributed by the first flow distribution component is greater than the flow rate of the medium distributed by the second flow distribution component.

[0079] Exemplarily, the different sizes of the guide holes 130 of at least two flow distribution components 100 include the different diameters of the guide holes 130 of at least two flow distribution components 100 .

[0080] Exemplarily, the guide hole 130 includes a first hole 131 and a second hole 132 that are connected. The first hole 131 is connected to the guide channel 201, and the second hole 132 is connected to the battery compartment 202. The diameter of the first hole 131 gradually decreases from one side of the flow distribution component 100 close to the guide channel 201 to the other side thereof, and the diameter of the first hole 131 is greater than the diameter of the second hole 132.

[0081] Exemplarily, the top of the guide plate 210 is flush with the top of the flow distribution component 100, or the end of the guide plate 210 away from the bottom plate 220 is flush with the end of the flow distribution component 100 away from the bottom plate 220. It should be understood that the top of the guide plate 210 and the top of the flow distribution component 100 defined in the embodiment of the present application are flush, which means that the two are roughly flush, within the range of processing error.

[0082] Exemplarily, the flow distribution component 100 and the frame 200 are detachably connected through a detachable structure. For example, the flow distribution component 100 includes a connected flow distribution body 110 and a first detachable structure 120, and the guide plate 210 is provided with a second detachable structure 211. The first detachable structure 120 and the second detachable structure 211 are detachably connected to achieve the detachable connection between the flow distribution component 100 and the frame 200. Specifically, when the flow distribution body 110 is installed in the installation hole 203, the first detachable structure 120 and the second detachable structure 211 are connected.

[0083] Exemplarily, one of the first detachable structure 120 and the second detachable structure 211 includes a connecting column, and the other includes a connecting groove, and the connecting column can be installed in the connecting groove. For example, the first detachable structure 120 includes one or more connecting columns, and the second detachable structure 211 includes multiple connecting grooves. Among them, the number of connecting grooves is the same as the number of connecting columns. The embodiment of the present application is described by taking the first detachable structure 120 including two connecting columns and the second detachable structure 211 including two connecting grooves as an example. It should be understood that the guide plate 210 is provided with multiple second detachable structures 211, and one second detachable structure 211 can be connected to the first detachable structure 120 of a flow distribution component 100.

[0084] For example, the cross section of the connecting column is an arc-shaped structure, and the shape and size of the connecting groove are adapted to the shape and size of the connecting column. It should be noted that the connecting column and the connecting groove may also adopt other shapes, which are not limited here.

[0085] Exemplarily, the top of the connecting column is flush with the top of the guide plate 210 and the top of the flow distribution body 110, or in other words, the top of the connecting column, the top of the guide plate 210 and the top of the flow distribution body 110 are substantially flush.

[0086] Exemplarily, the side wall of the flow distribution body 110 is flush with the side wall of the guide plate 210. The side wall of the guide plate 210 is connected to the top and bottom of the guide plate 210. The side wall of the flow distribution body 110 is connected to the top and bottom of the flow distribution body 110.

[0087] It should be noted that the manner in which the flow distribution component 100 achieves different flow rates of the distributed medium is not limited to using at least two flow distribution components 100 with the same number of guide holes 130 but different sizes.

[0088] In other optional embodiments, the number and size of the flow guide holes of at least two flow distribution components are different. This embodiment has the same technical effect as the above embodiment, and will not be described in detail here.

[0089] In other optional embodiments, the number of guide holes of at least two flow distribution components is different, but the size is the same. This embodiment has the same technical effect as the above embodiment, and will not be repeated here.

[0090] It should be noted that the methods for solving relevant technical problems are not limited to Figures 1 to 5 The battery rack described by way of example. Other battery racks may also be used to solve related technical problems. The following is an exemplary description in conjunction with other drawings.

[0091] like Figures 6 to 11 As shown, the flow distribution component 300 includes a mounting component 320 and a flow distribution component 310, the flow distribution component 310 and the mounting component 320 are connected, and the flow distribution component 310 can rotate relative to the mounting component 320 to change the direction of the medium distributed by the flow distribution component 310, or change the flow direction of the medium distributed by the flow distribution component 310. Specifically, the flow distribution component 310 may include a guide hole 315, and the flow distribution component 310 is configured to distribute the medium through its guide hole 315. During the rotation of the flow distribution component 310 relative to the mounting component 320, the flow direction of the medium distributed by the guide hole 315 can be changed. For details, please refer to Figure 6 and Figure 7 The different states of the flow distribution component 300 shown are specifically different flow directions of the medium distributed by the flow distribution component 310. It should be understood that the flow direction of the medium distributed by the flow distribution component 310 in the embodiment of the present application is not limited to Figure 6 and Figure 7 The two states shown in the embodiment of the present application are merely illustrative and will not be described one by one here.

[0092] When the flow distribution component 300 is applied to a battery rack immersed in a flow field, the flexibility of adjusting the flow distribution component 300 can be greatly improved. The position with a higher flow rate can reduce the resistance caused by the violent fluid turning. At the same time, targeted cooling is performed. When there is an obvious high-temperature area during testing or preliminary design, the adjacent reserved slots can be used to adjust the incident angle so that the flow distribution component 300 distributes the medium to the predetermined position, and the flow velocity of this part of the medium is increased in a targeted manner, and the temperature of the area is reduced. There is no need to redesign and develop a new battery rack, and it can be achieved by using only the same set of flow distribution components 300. Compared with related technologies, the embodiments of the present application can greatly reduce costs and shorten the research and development cycle, and can also improve the temperature uniformity of the battery device during the charging and discharging process.

[0093] Among them, the flow distribution component 310 and the installation component 320 can produce relative position changes, specifically, the flow distribution component 310 and the installation component 320 can rotate relative to each other. In one case, the flow distribution component 310 and the installation component 320 are connected by a rotating shaft 340. For example, one of the flow distribution component 310 and the installation component 320 is fixed to the rotating shaft 340, and the other is sleeved on the rotating shaft 340 and can rotate around the rotating shaft 340. Exemplarily, the rotating shaft 340 and the installation component 320 are fixed, such as an integral arrangement. The flow distribution component 310 is provided with an axial hole 316, and the rotating shaft 340 is installed in the axial hole 316. The flow distribution component 310 can rotate around the rotating shaft 340, so that the flow distribution component 310 rotates relative to the installation component 320.

[0094] It should be noted that the purpose of the flow distribution component 310 of the embodiment of the present application rotating relative to the mounting component 320 is to change the flow direction of the medium distributed by the guide hole 315. In practical applications, such as when the flow distribution assembly 300 is applied to a battery rack in an immersed flow field, the outlet 314 in the flow distribution component 310 connected to the guide hole 315 should always remain connected to the battery compartment of the battery rack. Therefore, during the rotation of the flow distribution component 310 relative to the mounting component 320, it is necessary to ensure that the outlet 314 of the flow distribution component 310 remains connected to the battery compartment of the battery rack, such as during the rotation of the flow distribution component 310 relative to the mounting component 320, the outlet 314 of the flow distribution component 310 remains on the other side of the mounting component 320.

[0095] Exemplarily, the flow distribution component 310 is further provided with an inlet 313 and an outlet 314 connected through the guide hole 315, that is, the inlet 313 and the outlet 314 connected by the guide hole 315. During the rotation of the flow distribution component 310 relative to the mounting component 320, the inlet 313 is maintained on one side of the mounting component 320, and the outlet 314 is maintained on the other side of the mounting component 320. It should be noted that the inlet 313 is maintained on one side of the mounting component 320, and can maintain communication with the guide channel of the battery rack.

[0096] Exemplarily, the flow distribution component 310 includes a connected flow distribution body 311 and a limiting structure 312, wherein the flow distribution body 311 is connected to the mounting component 320, and the flow distribution body 311 can rotate relative to the mounting component 320, and during the rotation of the flow distribution body 311 relative to the mounting component, the limiting structure 312 can limit the rotation range of the flow distribution body relative to the mounting component 320, so that the inlet 313 remains on one side of the mounting component 320, and the outlet 314 remains on the other side of the mounting component 320. In the case where the flow distribution assembly 300 is applied to a battery rack of an immersion flow field, the limiting structure 312 can keep the inlet 313 connected to the guide channel, and the outlet 314 connected to the battery compartment.

[0097] For example, the outlet 314 can be disposed on the restriction structure 312 , so that the guide hole 315 penetrates the restriction structure 312 and the flow distribution body 311 . In the embodiment of the present application, the restriction structure 312 is referred to as a nozzle.

[0098] In other optional embodiments, the outlet 314 is also provided on the flow distribution body 311. The limiting structure can be two limiting plate structures or limiting protrusion structures provided on both sides of the outlet 314, which can also play a role in limiting the rotation range of the flow distribution body 311 relative to the mounting component 320.

[0099] Exemplarily, the size of the inlet 313 is greater than the size of the outlet 314 .

[0100] Among them, the mounting component 320 is used as a carrier of the flow distribution component 310. When the flow distribution component 300 of the embodiment of the present application is applied to a battery rack of an immersed flow field, the mounting component 320 is used to be detachably mounted in the mounting hole of the battery rack. For example, the battery rack may include a frame body with a mounting hole and a flow distribution component 300, and the flow distribution component 300 is detachably mounted on the frame body. The following is an exemplary description in conjunction with the accompanying drawings of the battery rack.

[0101] The mounting component 320 includes a first mounting portion 321, an intermediate mounting portion 323 and a second mounting portion 322 connected in sequence, that is, the intermediate mounting portion 323 connects the first mounting portion 321 and the second mounting portion 322, and the first mounting portion 321, the intermediate mounting portion 323 and the second mounting portion 322 can be integrally arranged. The intermediate mounting portion 323 is connected to the bottom end of the first mounting portion 321 and the bottom end of the second mounting portion 322.

[0102] The first mounting portion 321, the middle mounting portion 323 and the second mounting portion 322 together define a mounting space 324, the flow distribution body 310 is mounted in the mounting space 324, and the middle mounting portion 323 is located below the flow distribution body 310. The rotating shaft 340 is connected to the middle mounting portion 323, such as being integrally arranged, and the rotating shaft 340 is located between the first mounting portion 321 and the second mounting portion 322. Exemplarily, the middle mounting portion 323 is of a regular shape, and the rotating shaft 340 is arranged at the center of the middle mounting portion 323.

[0103] Exemplarily, the top of the first mounting portion 321, the top of the second mounting portion 322, and the top of the flow distribution body 310 are flush. In other words, the end of the first mounting portion 321 away from the middle mounting portion 323, the end of the second mounting portion 322 away from the middle mounting portion 323, and the end of the flow distribution body 310 away from the middle mounting portion 323 are flush. It should be understood that the flushing of the top of the first mounting portion 321, the top of the second mounting portion 322, and the top of the flow distribution body 310 defined in the embodiment of the present application means that the tops of the three are roughly flush, which is within the range of processing error.

[0104] Exemplarily, the first mounting portion 321 includes a first limiting surface 3211, and when the limiting structure 312 such as a nozzle abuts against the first mounting portion 321, one side of the nozzle 312 abuts against the first limiting surface 3211. Exemplarily, the second mounting portion 3212 includes a second limiting surface 3221, and when the nozzle 312 abuts against the second mounting portion 322, the other side of the nozzle 312 abuts against the second limiting surface 3221. It should be understood that the two side surfaces of the nozzle 312 are adapted to the shapes of the first limiting surface 3211 and the second limiting surface 3221, so that in the process of adjusting the flow distribution body 311 to rotate relative to the mounting component 320, the nozzle 312 fits with the first limiting surface 3211 when it is in contact with the first mounting portion 321, and the nozzle 312 fits with the second limiting surface 3221 when it is in contact with the second mounting portion 322. This not only increases the contact stability between the nozzle 312 and the first mounting portion 321 and the second mounting portion 322, but also increases the matching stability, and the nozzle 312 fits with the first limiting surface 3211 and the second limiting surface 3221, so that the contact area is large enough and is not easily damaged during actual operation.

[0105] Exemplarily, the first limiting surface 3211 is connected to the side of the first mounting portion 321 and is tilted, and the second limiting surface 3221 is connected to the side of the second mounting portion 322 and is tilted. Exemplarily, the inclination between the first limiting surface 3211 and the first mounting portion 321 is the same as the inclination between the second limiting surface 3221 and the second mounting portion 322.

[0106] The first limiting surface 3211 and the second limiting surface 3221 are arranged opposite to each other, and the distance between the first limiting surface 3211 and the second limiting surface 3221 gradually decreases from one side of the mounting portion 320 toward the other side of the mounting portion 320, so that the first limiting surface 3211 and the second limiting surface 3221 are in an "eight" shape. The first limiting surface 3211 and the second limiting surface 3221 are close to one side of the mounting portion 320 and away from the other side of the mounting portion 320.

[0107] Exemplarily, the shape of the first limiting surface 3211 is substantially the same as the shape of the second limiting surface 3221, such as the first limiting surface 3211 and the second limiting surface 3221 are both rectangular. Exemplarily, the size of the first limiting surface 3211 is substantially the same as the size of the second limiting surface 3221.

[0108] Exemplarily, the first mounting portion 321 includes a first arcuate surface 3212, the second mounting portion 322 includes a second arcuate surface 3222, and the first arcuate surface 3212 and the second arcuate surface 3222 are opposite to each other. The peripheral outer surface of the flow distribution body 310 is adapted to the first arcuate surface 3212 and the second arcuate surface 3222. This makes the connection between the flow distribution component 300 and the mounting component 320 more compact and stable.

[0109] Exemplarily, the first mounting portion 321 and the second mounting portion 322 are symmetrically arranged relative to the middle mounting portion 323 .

[0110] In practical applications, for the adjusted flow distribution component 310, due to the flow of the medium or other external factors, the flow distribution component 310 is likely to produce a displacement change relative to the mounting component 320. It should be understood that the displacement change defined in the embodiment of the present application is a rotation change of the flow distribution component 310 relative to the mounting component 320. Therefore, the flow distribution assembly 300 of the embodiment of the present application further includes a positioning component 330, which connects the mounting component 320 and the flow distribution component 310 to limit the flow distribution component 310 from rotating relative to the mounting component 310.

[0111] It should be noted that the positioning component 330 connects the installation component 320 and the flow distribution component 310 after the flow distribution component 310 is adjusted to a suitable position.

[0112] Exemplarily, the mounting component 320 is provided with at least one first positioning groove 326, and the flow distribution component 310 is provided with a plurality of second positioning grooves 317, and the plurality of second positioning grooves 317 are arranged at intervals along the rotation direction of the flow distribution component 311. The positioning component 330 can be installed in one first positioning groove 326 and one second positioning groove 317 to limit the flow distribution component 310 from rotating relative to the mounting component 320.

[0113] Exemplarily, the mounting component 320 has two first positioning grooves 326 , one first positioning groove 326 is formed in the first mounting portion 321 , and the other first positioning groove 326 is formed in the second mounting portion 322 , and the first positioning groove 326 of the first mounting portion 321 and the first positioning groove 326 of the second mounting portion 322 are opposite.

[0114] It should be noted that the positioning method between the flow distribution component 310 and the installation component 320 implemented by the positioning component 330 in the embodiment of the present application is not limited to this. The embodiment of the present application does not limit how the positioning component 330 limits the positioning method between the flow distribution component 310 and the installation component 320.

[0115] Exemplarily, at least one of the first mounting portion 321 and the second mounting portion 322 is provided with a first detachable structure 325, and at least one of the first mounting portion 321 and the second mounting portion 322 is detachably connected to the frame of the battery rack through the first detachable structure 325. Exemplarily, both the first mounting portion 321 and the second mounting portion 322 are provided with a first detachable structure 325.

[0116] Exemplarily, the first detachable structure 325 is disposed on a side of the first mounting portion 321 and the second mounting portion 322 away from the flow distribution component 310 .

[0117] It should be noted that the flow distribution component 310 of the embodiment of the present application is also detachably connected to the rotating shaft 340 and the mounting component 320. Therefore, the flow distribution component 310 of suitable specifications can be installed on the rotating shaft 340 and the mounting component 320 according to the needs. In some cases, the mounting components 320 of multiple flow distribution components 300 have the same shape, and the guide holes 315 of each flow distribution component 310 in the multiple flow distribution components 300 have the same size, that is, the shape of each flow distribution component 310 is the same.

[0118] In other cases, the shapes of the mounting components 320 of the multiple flow distribution components 300 are the same, while the sizes of the guide holes 315 of the flow distribution components 310 in the multiple flow distribution components 300 are different. Therefore, the embodiment of the present application can not only adjust the flow direction of the medium distributed by the flow distribution component 310, but also replace the flow distribution components 310 of different specifications to change the flow rate of the medium distributed by the flow distribution component 310.

[0119] In other cases, the shapes of the mounting components 320 of the multiple flow distribution components 300 are the same, while the number of the guide holes 315 of each flow distribution component 310 in the multiple flow distribution components 300 is different. Therefore, the embodiment of the present application can not only adjust the flow direction of the medium distributed by the flow distribution component 310, but also replace the flow distribution components 310 of different specifications to change the flow rate of the medium distributed by the flow distribution component 310.

[0120] The flow guide holes 315 of each flow distribution component 310 may be different in size or number, which can be referred to in Figures 1 to 5 The contents shown will not be repeated here.

[0121] like Fig.12 and Fig.13 As shown, the battery rack 30 includes a rack body 400 and a plurality of flow distribution components 300, and the flow distribution components 300 are detachably connected to the rack body 400. Therefore, the number of flow distribution components 300 installed on the rack body 400 and the installation position can be selected according to actual needs. Fig.12The schematic diagram shows the installation relationship between a flow distribution component 300 and a plurality of installation components of the flow distribution components 300 and a frame 400. Fig.12 For an exemplary view, Fig.12 The number of flow distribution components 300 shown does not constitute a limitation on the number of flow distribution components 300 in the embodiment of the present application.

[0122] Among them, multiple flow distribution components 300 can refer to Figures 6 to 11 The flow distribution assembly 300 is shown and will not be described in detail here. It should be understood that the detachable connection between the flow distribution assembly 300 and the frame 400 can be understood as two parts. Specifically, the mounting component 320 of the flow distribution assembly 300 is detachably connected to the frame 400, and the flow distribution component 310 is detachably connected to the mounting component 320.

[0123] It should be noted that the mounting part 320 and the flow distribution part 310 of any flow distribution assembly 300 may not need to be mounted on the frame 400 together, such as the mounting part 320 of a part of the flow distribution assembly 300 is mounted on the frame 400, while the flow distribution part 310 is not mounted on the frame 400. For another example, the mounting part 320 and the flow distribution part 310 of all the flow distribution assemblies 300 are mounted on the frame 400.

[0124] Exemplarily, the shapes and sizes of the various mounting components 320 of the battery rack 30 are substantially the same, which is conducive to processing and forming. Among them, the external contours of the various flow distribution components 310 are substantially consistent, which is also conducive to processing and forming. In an optional embodiment, the ability of each flow distribution component 310 to distribute the medium is substantially the same, for example, the size of the guide holes 315 of each flow distribution component 310 is substantially the same, and the number of guide holes 315 is substantially the same. In other optional embodiments, the guide holes 315 of at least two flow distribution components 310 of each flow distribution component 310 are different in size, such as different apertures. For specific examples, please refer to Figures 1 to 5 In other optional embodiments, at least two flow distribution components 310 of each flow distribution component 310 have different numbers of guide holes 315. For specific examples, please refer to Figures 1 to 5 The contents shown will not be repeated here.

[0125] The battery rack 30 has a length direction D3 and a width direction D4 , and the length direction D3 and the width direction D4 are substantially perpendicular to each other.

[0126] The overall structure of the frame 400 of the embodiment of the present application is similar to the overall structure of the frame 200, such as the frame 400 is provided with a flow guide channel 401, multiple battery compartments 402 and multiple mounting holes 403, multiple battery compartments 402 are connected to multiple mounting holes 403, and one battery compartment 402 is connected to at least one mounting hole 403.

The flow guide channel 401 is connected to multiple mounting holes 403, and multiple mounting holes 403 are connected to the flow guide channel 401 and multiple battery compartments 402. It should be understood that when the mounting hole 403 is not installed with the flow distribution component 400, the flow guide channel 401 and the multiple battery compartments 402 are directly connected through the multiple mounting holes 403.

[0127] The multiple battery compartments 402 can be divided into two groups, one of which is located on one side of the guide channel 403, and the other is located on the other side of the guide channel 403. One group of battery compartments 402, the guide channel 403, and the other group of battery compartments 402 are arranged in sequence in the width direction D4 of the battery rack 30. There are multiple battery compartments 402 on both sides of the guide channel 403, and the multiple battery compartments 402 on the same side of the guide channel 403 are arranged in sequence along the length direction D3 of the battery rack 30.

The guide plate 410, the side plate 430 and the bottom plate 420 together define a guide channel 401. A plurality of mounting holes 403 are all provided on the guide plate 410.

[0129] Exemplarily, the side plate 430 is connected to the periphery of the bottom plate 420, and the plurality of partitions 440 and the guide plate 410 are surrounded by the side plate 430.

[0131] The plurality of partitions 440 can be defined as two groups, one group of partitions 440 corresponding to one group of battery compartments 402. There is one battery compartment 402 between two adjacent partitions 440 in one group of partitions 440, and two of the partitions 440 in one group of partitions 440 and two sides of the side plate 430 form two battery compartments 402.

[0138] The flow distribution component 310 is used to distribute the medium placed in the flow guide channel 401 to the battery compartment 2402 connected thereto through its flow guide holes 315 .

[0139] The guide plate 410 is provided with a second detachable structure 411, and the first detachable structure 325 and the second detachable structure 411 are detachably connected to realize the detachable connection between the mounting component 320 and the frame 400. Specifically, when the mounting component 320 is installed in the mounting hole 403, the first detachable structure 325 and the second detachable structure 411 are connected.

[0140] Exemplarily, one of the first detachable structure 325 and the second detachable structure 411 includes a connecting column, and the other includes a connecting groove, and the connecting column can be installed in the connecting groove. For example, the first detachable structure 325 includes one or more connecting columns, and the second detachable structure 411 includes one or more connecting grooves. Among them, the number of connecting grooves is the same as the number of connecting columns. The embodiment of the present application is described by taking the first detachable structure 325 including two connecting columns and the second detachable structure 411 including two connecting grooves as an example. It should be understood that the guide plate 410 is provided with a plurality of second detachable structures 411, and one detachable structure 411 can be connected to the first detachable structure 325 of a mounting component 320.

[0141] For example, the cross section of the connecting column is an arc-shaped structure, and the shape and size of the connecting groove are adapted to the shape and size of the connecting column.

The flow distribution components 500 are detachably connected to the rack body 400 and can rotate relative to the rack body 600. Fig.12 and Fig.13 In the battery rack 50 shown in the embodiment of the present application, the flow distribution component 500 can rotate directly relative to the rack 600, which is different from the flow distribution component 310 rotating relative to the mounting component 320, and the mounting component 320 is detachably connected to the rack 400.

[0150] The guide channel 601 , the guide inlet 604 , and the battery compartment 602 of the frame 600 may all refer to those of the frame 400 , and will not be described in detail herein.

[0151] The side plates 630 , the bottom plate 620 , the partition plates 640 and the joints 450 of the frame 600 may all refer to the frame 400 , and will not be described in detail herein.

[0152] It should be noted that the flow distribution assembly 300 of the embodiment of the present application is designed separately from the part connected to the frame 400 and the part rotating relative to the frame 400. Specifically, the flow distribution assembly 300 includes a flow distribution component 310 and a mounting component 320. The battery rack 30 and the battery rack 50 are compared in combination with actual applications.

[0153] In practical applications, the nozzle 312 of the flow distribution component 310 may be optimized. When structural optimization is required, since the flow distribution component 310 and the mounting component 320 are detachably connected, the flow distribution component 310 and the mounting component 320 can be connected in a coordinated manner without modifying the frame 400. The structure of the connection between the mounting component 320 and the frame 400 does not need to be changed.

[0154] Since the guide plate 610 of the frame 600 is provided with a rotating shaft 612, the rotating shaft 612 can be mounted on the guide plate 610 by machining or riveting, but the rotating shaft 612 is easily damaged or deformed during transportation and assembly. The rotating shaft 340 is connected to the mounting component 320, which can be realized by injection molding. Even if it is damaged, it can be replaced at a low cost, and it is easier to do incoming material inspection, which is beneficial to production and manufacturing.

[0155] Compared with the flow distribution component 300, the flow distribution component 500 omits the installation component 320, so that the flow distribution component 500 occupies a small space and can be applied to more subtle partitions.

[0156] The flow distribution assembly and battery rack provided in the embodiments of the present application are introduced in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. At the same time, for those skilled in the art, according to the ideas of the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
