Detailed description of the embodiments

[0015] Embodiments of the present application provide a flow distribution component, a flow distribution assembly, and a battery tray. The flow distribution component and / or the flow distribution assembly can be attached to the battery tray. It should be understood that the battery tray can include the flow distribution component or the flow distribution assembly. It should further be understood that the flow distribution component, the flow distribution assembly, and the battery tray can all be used for immersion scenarios; for example, the flow distribution component, the flow distribution assembly, and the battery tray can all be used in the testing of battery devices. Those skilled in the art will appreciate that the flow distribution component and the flow distribution assembly are not limited to immersion scenarios and can be used in other liquid scenarios.

[0016] In the following, a clear and complete description of the technical solution in the embodiments of the present application is given in conjunction with the attached drawings.

[0017] As in Fig. 1 to Fig. 5, a battery tray 10 includes a support body 200 and a plurality of flow distribution components 100. The plurality of flow distribution components 100 are detachably connected to the support body 200. Therefore, the number and installation positions of the flow distribution components 100 installed on the support body 200 can be selected according to actual needs. Fig. 1 schematically shows an installation relationship between a flow distribution component 100 and the support body 200. Fig. 1 is an exemplary representation, and the number of Fig. 1 does not represent a limitation on the number of flow distribution components 100 of the embodiments of the present application.

[0018] It should be noted that in related battery devices, the battery tray is provided with too many flow guide holes. The flow guide holes formed directly on the battery tray are used to guide media. In related technologies, the plurality of flow guide holes of the battery tray essentially have the same flow velocity and flow direction. However, in practical applications in the battery device, the temperature of the battery modules housed in a plurality of submersible battery compartments may be uneven due to the arrangement of the battery modules, boundary convection, and other factors.

[0019] It should also be noted that in the immersion scenarios of related technologies, a flow field of the immersion scenario requires adjusting the structure of the battery tray according to different media, resulting in high costs. Furthermore, the flow distribution of an immersion scenario test prototype cannot be flexibly adjusted, resulting in high investment costs and long research and development cycles for the immersion scenario test prototype.

[0020] Since the carrier body 200 and the plurality of flow distribution components 100 are detachably connected to each other, the flexibility of using the flow distribution components 100 can be increased to a certain extent. For example, in a first situation, the carrier body 200 needs to be equipped with N flow distribution components 100, while in a second situation, the carrier body 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 also be other situations not individually illustrated here. Therefore, the battery carrier 10 can improve the flexibility of using the flow distribution components 100 of the immersion scenario test prototype to a certain extent, thereby reducing costs and shortening the research and development cycle to a certain extent.That is, since the plurality of flow distribution components 100 can be detachably connected to the support body 200, the number of flow distribution components 100 of the present application can be configured according to actual needs.

[0021] For example, the contours of the plurality of flow distribution components 100 are substantially uniform, which facilitates processing and molding of the flow distribution components 100, such as using injection molding to form a plurality of flow distribution components 100.

[0022] Each flow distribution component 100 can distribute a medium, or to say that the flow distribution component 100 is configured to distribute the medium. In some cases, each flow distribution component 100 can distribute a liquid. It can also be understood that each flow distribution component 100 can transfer liquid.

[0023] For example, at least two of the plurality of flow distribution components 100 distribute the medium at different flow rates. The fact that the at least two flow distribution components 100 distribute the medium at different flow rates can also be understood to mean that the at least two flow distribution components have different medium flow rate distribution functions. Therefore, the present application can flexibly configure the flow distribution components 100 with different medium flow rate functions according to different needs, such as flexibly configuring 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 can be configured with a larger medium flow rate so that the flow distribution component 100 can provide a larger medium flow rate for the predetermined position, so that the medium flow rate at the predetermined position can be increased to accelerate the reduction of the temperature at the predetermined position. This can improve the temperature uniformity of the battery device during charging and discharging.

[0024] That is, the present application can flexibly configure various flow distribution components 100 according to different needs. For example, when the temperature at a predetermined location is high, a flow distribution component 100 with a higher medium flow rate can be used to distribute the medium, which can improve the temperature uniformity of the battery device during charging and discharging.

[0025] Furthermore, the present application can configure the flow distribution components 100 with different functions for the medium flow rate as needed, so that the support body 200 can be adapted to different needs, and the flow distribution components 100 installed on the support body 200 can be determined according to the different needs. Compared with related technologies in which a support body is adapted to one type of need, or to related technologies in which a support body is adapted to a medium, or to related technologies in which a support body is adapted to a medium flow rate, the present application can significantly reduce costs.In addition, the flow allocation of the immersion scene test prototype can be flexibly adjusted, which can reduce the investment cost of the immersion scene test prototype and shorten the research and development cycles.

[0026] Since the contours of the plurality of flow distribution components 100 of the present application are substantially uniform and at least two flow distribution components 100 distribute the medium at different flow rates, in practical applications, the flow distribution components 100 of a desired specification can be installed at predetermined positions of the support body 200 according to actual needs. During an actual test operation, it is convenient to set the flow distribution components 100 with different specifications for testing without installation obstacles.

[0027] The battery carrier 10 has a longitudinal direction D1 and a width direction D2, wherein the longitudinal direction D1 and the width direction D2 are substantially perpendicular to one another.

[0028] The support body 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 communicate with the plurality of mounting holes 203, and a battery compartment 202 communicates with at least one mounting hole 203. In the present application, a battery compartment 202 and a mounting hole 203 are considered as an example of a connection. The flow guide channel 201 communicates with the plurality of mounting holes 203. The plurality of mounting holes 203 communicate with the flow guide channel 201 and the plurality of battery compartments 202. It is understood that the flow guide channel 201 communicates directly with the plurality of battery compartments 202 through the plurality of mounting holes 203 when the mounting holes 203 are not installed with the flow distribution components 100.

[0029] The plurality of battery compartments 202 can be divided into two groups, one group being arranged on one side of the flow guide channel 203 and the other group being arranged on the other side of the flow guide channel 203. One group of battery compartments 202, the flow guide channel 203, and the other group of battery compartments 202 are arranged one behind the other in the width direction D2 of the battery tray 10. There are a plurality of battery compartments 202 on both sides of the flow guide channel 203, and the plurality of battery compartments 202 on the same side of the flow guide channel 203 are arranged sequentially at intervals along the longitudinal direction D1 of the battery tray 10.

[0030] As in Fig. 1 to Fig. 4, the support body 200 includes a flow guide plate 210, a bottom plate 220, a side plate 230, and a plurality of partition plates 240. The flow guide plate 210, the side plate 230, and the partition plates 240 are all connected to the same surface of the bottom plate 220 to collectively define the plurality of battery compartments 202. The flow guide plate 210, the side plate 230, and the bottom plate 220 together form the flow guide channel 201. The plurality of mounting holes 203 are all formed on the flow guide plate 210.

[0031] For example, the side plate 230 is connected to the peripheral edges of the bottom plate 220, and the plurality of partition plates 240 and the flow guide plate 210 are surrounded by the side plate 230. The side plate 230 may, for example, surround and form a cuboid-shaped space. One end of the plurality of partition plates 240 is connected to an inner surface of the side plate 230, and the other end of the plurality of partition plates 240 is connected to the flow guide plate 210.

[0032] For example, there are two flow guide plates 210 spaced apart from each other. The two flow guide plates 210 are spaced apart from each other by the flow guide channel 201. One end of the two flow guide plates 210 is connected to an inner surface of one side of the side plate 230, and the other end of the two flow guide plates 210 is connected to an inner surface of the other side of the side plate 230.

[0033] For example, the plurality of partition plates 240 may be divided into two groups, with one group of partition plates 240 corresponding to one group of battery compartments 202. One battery compartment 202 is spaced between two adjacent partition plates 240 in a group of partition plates 240, and two corresponding battery compartments 202 are formed between two partition plates 240 in a group of partition plates 240 and two sides of the side plate 230.

[0034] Each flow guide plate 210 is provided with a plurality of mounting holes 203, and each mounting hole 203 can directly communicate with a battery compartment 202 and the flow guide channel 201. For example, the number of mounting holes 203 formed in the two flow guide plates 210 is the same. For example, the positions of the mounting holes 203 formed in one of the two flow guide plates 210 are opposite to the positions of the mounting holes 203 formed in the other of the two flow guide plates 210. It should be noted that the positions and number of mounting holes 203 formed on each flow guide plate 210 can be adjusted according to actual needs.

[0035] For example, the two flow guide plates 210 are substantially flush with each other at the surfaces remote from the base plate 220.

[0036] For example, the height of the two flow guide plates 210 is not higher than the height of the side plate 230. For example, a side of the two flow guide plates 210 facing away from the bottom plate 220 is substantially flush with a side of the side plate 230 facing away from the bottom plate 220. Another example is that the side of the two flow guide plates 210 facing away from the bottom plate 220 is slightly lower than the side plate 230. In other words, a vertical distance between the two flow guide plates 210 and the bottom plate 220 is not greater than a vertical distance between the side plate 230 and the bottom plate 220.

[0037] As in Fig. 1 to Fig. 4, the support body 200 is further provided with a flow inlet 204 which penetrates the side plate 230 and communicates with the flow guide channel 201.

[0038] As in Fig. 1 to Fig. 4, the support body 200 is further provided with a connector 250. The connector 250 is connected to the side plate 230 and is connected to an outer surface of the side plate 230. The flow inlet 204 penetrates the connector 250 and the side plate 230 and communicates with the flow guide channel 201.

[0039] Each battery compartment 202 can accommodate one cell or one battery component.

[0040] The 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 support body 200, the plurality of flow distribution components 100 are installed in the plurality of mounting holes 203, and a flow distribution component 100 is installed in a corresponding mounting hole 203.

[0041] Each of the flow distribution components 100 is configured to distribute the medium introduced into the flow guide channel 201 into the battery compartment 202, and at least two of the flow distribution components 100 can distribute the medium introduced into the flow guide channel 201 into the battery compartments 202 at different flow rates. For example, each flow distribution component 100 is provided with at least one flow guide hole 130, and the number of flow guide holes 130 on each of the plurality of flow distribution components 100 is the same. Each flow distribution component 100 is configured to distribute the medium introduced into the flow guide channel 201 into the battery compartment 202 through its flow guide hole 130, which communicates with the flow distribution component 100.Alternatively, the flow distribution component 100 may be considered to be configured to distribute the medium through its flow guide hole 130, for example, to distribute the medium into the battery compartment 202 communicating with the flow distribution component 100, or to say, to distribute the medium into the correspondingly communicated battery compartment 202.

[0042] For example, the flow guide holes 130 of at least two of the flow distribution components 100 have different sizes. For example, the plurality of flow distribution components 100 includes one or more first flow distribution components and one or more second flow distribution components. The difference between the first flow distribution component and the second flow distribution component is that the size of their flow guide holes is different. For example, the flow guide hole of the first flow distribution component is larger than the flow guide hole 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 first flow distribution component to distribute the medium is greater than that of the second flow distribution component, or in other words, the flow velocity of the medium distributed by the first flow distribution component is greater than the flow velocity of the medium distributed by the second flow distribution component.

[0043] The different sizes of the flow guide holes 130 of the at least two flow distribution components 100 include, for example, the different diameters of the flow guide holes 130 of the at least two flow distribution components 100.

[0044] For example, the flow guide hole 130 includes a first hole 131 and a second hole 132 that communicate with each other. The first hole 131 communicates with the flow guide channel 201, and the second hole 132 communicates with the battery compartment 202. The diameter of the first hole 131 gradually decreases from one side of the flow distribution component 100 near the flow guide channel 201 to the other side of the flow distribution component 100, and the diameter of the first hole 131 is larger than the diameter of the second hole 132.

[0045] For example, an upper end of the flow guide plate 210 is flush with an upper end of the flow distribution component 100, or in other words, an end of the flow guide plate 210 remote from the bottom plate 220 is flush with an end of the flow distribution component 100 remote from the bottom plate 220. It should be understood that the upper end of the flow guide plate 210 and the upper end of the flow distribution component 100 defined in the embodiments of the present application are substantially flush with each other, which is within a processing error range.

[0046] For example, the flow distribution component 100 and the support body 200 are detachably connected to each other via detachable structures. Thus, the flow distribution component 100 includes a flow distribution body 110 and a first detachable structure 120 that are connected to each other, and the flow 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 each other to establish a detachable connection between the flow distribution component 100 and the support body 200. In particular, the first detachable structure 120 and the second detachable structure 211 are connected to each other when the flow distribution body 110 is installed in the mounting hole 203.

[0047] For example, one of the first detachable structure 120 and the second detachable structure 211 includes a connecting column, and the other includes a connecting slot, and the connecting column can be installed in the connecting slot. For example, the first detachable structure 120 includes one or more connecting columns, and the second detachable structure 211 includes a plurality of connecting slots. The number of connecting slots is the same as the number of connecting columns. The embodiments of the present application are described using the first detachable structure 120 with two connecting columns and the second detachable structure 211 with two connecting slots as examples.It is understood that the flow guide plate 210 is provided with a plurality of second removable structures 211, and each second removable structure 211 can be connected to a corresponding first removable structure 120 of a flow distribution component 100.

[0048] For example, the cross section of the connecting column is an arc-shaped structure, and the shape and size of the connecting slot are adapted to the shape and size of the connecting column. It should be noted that the connecting column and the connecting slot can also take other shapes, which are not limited here.

[0049] For example, an upper end of the connecting column is flush with an upper end of the flow guide plate 210 and an upper end of the flow distribution body 110. Or in other words, the upper end of the connecting column, the upper end of the flow guide plate 210, and the upper end of the flow distribution body 110 are substantially flush.

[0050] For example, the side wall of the flow distribution body 110 is flush with the side wall of the flow guide plate 210. The side wall of the flow guide plate 210 is connected to the upper end and the lower end of the flow guide plate 210. The side wall of the flow distribution body 110 is connected to the upper end and the lower end of the flow distribution body 110.

[0051] It should be noted that the manner in which the flow distribution component 100 achieves different medium flow velocities is not limited to the flow guide holes 130 of at least two of the flow distribution components 100 having the same number but different sizes.

[0052] In other optional embodiments, the flow guide holes of at least two flow distribution components have a different number and different sizes. This embodiment has the same technical effects as the embodiments of the present application, which will not be described again here.

[0053] In other optional embodiments, the flow guide holes of at least two flow distribution components have a different number but the same size. This embodiment has the same technical effects as the above-mentioned embodiments of the present application, which will not be described again here.

[0054] It should be noted that the manner in which the technical effects of the embodiments of the present application are achieved is not limited to the Fig. 1 to Fig. 5. Other battery carriers may also be used to achieve corresponding technical effects. An exemplary description is given below in conjunction with other drawings.

[0055] As in Fig. 6 to Fig. 11, a flow distribution assembly 300 includes a mounting component 320 and a flow distribution component 310. The flow distribution component 310 is connected to the mounting component 320 and can rotate relative to the mounting component 320 to change a flow direction in which the flow distribution component 310 distributes the medium, or to say, to change the flow direction of the medium distributed by the flow distribution component 310. In some cases, the flow distribution component 310 may have a flow guide hole 315, and the flow distribution component 310 is configured to distribute a medium through the flow guide hole 315 thereof. During rotation of the flow distribution component 310 relative to the mounting component 320, the flow direction of the medium distributed through the flow guide hole 315 can be changed.In particular, various states of the flow distribution assembly 300 can be shown in . Fig. 6 and Fig. 7, which show 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 embodiments of the present application is not limited to the two Fig. 6 and Fig. 7. The embodiments of the present application are illustrative only and will not be explained individually here.

[0056] When the flow distribution assembly 300 is applied to a battery tray in a submerged flow field, the adjustment flexibility of the flow distribution assembly 300 can be significantly improved. At positions with high flow velocities, the resistance caused by the sharp rotation of the fluid can be reduced. Furthermore, targeted cooling can be performed. For obvious high-temperature areas during testing or preliminary design, adjacent reserved slots can be used to adjust an angle of incidence so that the flow distribution assembly 300 distributes the medium to the predetermined position, thereby selectively increasing the medium flow velocity in that part and lowering the temperature in that area by using only the same set of flow distribution assemblies 300, without the need to redesign and develop new battery trays.Compared with related technologies, the present application can significantly reduce costs, shorten research and development cycles, and improve the temperature uniformity of battery devices during charging and discharging.

[0057] The flow distribution component 310 and the mounting component 320 can change their position relative to each other. For example, the flow distribution component 310 and the mounting component 320 can be rotated relative to each other. In one situation, the flow distribution component 310 and the mounting component 320 are connected via a rotation shaft 340. For example, one of the two components, namely the flow distribution component 310 and the mounting component 320, is fixedly connected to the rotation shaft 340, while the other component is inserted onto the rotation shaft 340 and can rotate about the rotation shaft 340. For example, the rotation shaft 340 and the mounting component 320 are fixedly connected to each other, e.g., as an integral part.The flow distribution component 310 is provided with a shaft hole 316, and the rotation shaft 340 is installed in the shaft hole 316 so that the flow distribution component 310 can rotate about the rotation shaft 340, thereby achieving rotation of the flow distribution component 310 relative to the mounting component 320.

[0058] It should be noted that the flow distribution component 310 of the present application rotates relative to the mounting component 320, which can change the flow direction of the medium distributed through the flow guide hole 315. In practical applications, when the flow distribution assembly 300 is mounted on a battery tray in a submerged flow field, an outlet 314 of the flow distribution component 310 communicating with the flow guide hole 315 should always remain connected to the battery tray's battery compartment. Therefore, during rotation of the flow distribution component 310 relative to the mounting component 320, it must be ensured that the outlet 314 of the flow distribution component 310 maintains communication with the battery tray's battery compartment.For example, the outlet 314 of the flow distribution component 310 is maintained on the other side of the mounting component 320 facing the battery compartment during rotation of the flow distribution component 310 relative to the mounting component 320.

[0059] For example, the flow distribution component 310 is further provided with an inlet 313 and an outlet 314, which communicate with each other through the flow guide hole 315. That is, the flow guide hole 315 connects the inlet 313 and the outlet 314. During rotation of the flow distribution component 310 relative to the mounting component 320, the inlet 313 is held on one side of the mounting component 320 facing the flow guide channel, and the outlet 314 is held on the other side of the mounting component 320 facing the battery compartment. It should be noted that the inlet 313 is held on one side of the mounting component 320 to maintain communication with the flow guide channel of the battery tray.

[0060] The flow distribution component 310 includes, for example, a flow distribution body 311 and a limiting structure 312 that are connected to each other. The flow distribution body 311 is connected to the mounting component 320, and the flow distribution body 311 can be rotated relative to the mounting component 320. During rotation of the flow distribution body 311 relative to the mounting component 320, the limiting structure 312 can limit the range of rotation of the flow distribution body 311 relative to the mounting component 320 such that the inlet 313 is held on one side of the mounting component 320 while the outlet 314 is held on the other side of the mounting component 320.In the event that the flow distribution assembly 300 is mounted on a battery tray in a submerged flow field, the restriction structure 312 may maintain the inlet 313 in communication with the flow guide channel while the outlet 314 remains in communication with the battery compartment.

[0061] For example, the outlet 314 can be arranged on the restriction structure 312 such that the flow guide hole 315 penetrates the restriction structure 312 and the flow distribution body 311. In the embodiments of the present application, the restriction structure 312 is referred to as a nozzle. The inlet 313 is arranged on the flow distribution body 311.

[0062] In other optional embodiments, the outlet 314 is also arranged on the flow distribution body 311. The limiting structure may be two limiting plate structures arranged on either side of the outlet 314 or a limiting protrusion structure, which may also play a role in limiting the rotational range of the flow distribution body 311 relative to the fastening element 320.

[0063] For example, the size of the inlet 313 is larger than the size of the outlet 314.

[0064] The mounting component 320 is used as a support for the flow distribution component 310. When the flow distribution assembly 300 of the present application is attached to a battery tray in a submerged flow field, the mounting component 320 is configured to be removably installed in the mounting hole of the battery tray. For example, the battery tray may include a support body with mounting holes and flow distribution assemblies 300, wherein the flow distribution assemblies 300 may be removably attached to the support body. An exemplary description of a battery tray is provided below in conjunction with the accompanying drawings.

[0065] The mounting component 320 includes a first mounting portion 321, a middle mounting portion 323, and a second mounting portion 322, which are sequentially connected. That is, the middle mounting portion 323 connects the first mounting portion 321 and the second mounting portion 322. The first mounting portion 321, the middle mounting portion 323, and the second mounting portion 322 can be mounted as a whole. The middle mounting portion 323 is connected to a lower end of the first mounting portion 321 and a lower end of the second mounting portion 322.

[0066] The first mounting portion 321, the middle mounting portion 323, and the second mounting portion 322 together form a mounting space 324. The flow distribution body 311 is mounted in the mounting space 324, and the middle mounting portion 323 is located below the flow distribution body 311. The rotation shaft 340 is connected to the middle mounting portion 323, for example, integrally arranged, and the rotation shaft 340 is located between the first mounting portion 321 and the second mounting portion 322. For example, the middle mounting portion 323 has a regular shape, and the rotation shaft 340 is arranged in the center of the middle mounting portion 323.

[0067] For example, an upper end of the first mounting portion 321, an upper end of the second mounting portion 322, and an upper end of the flow distribution body 310 are flush. In other words, an end of the first mounting portion 321 remote from the middle mounting portion 323, an end of the second mounting portion 322 remote from the middle mounting portion 323, and an end of the flow distribution body 310 remote from the middle mounting portion 323 are flush. It should be understood that the upper end of the first mounting portion 321, the upper end of the second mounting portion 322, and the upper end of the flow distribution body 310 defined in the present application are substantially flush, which means that the upper ends of the three are substantially flush, within the range of processing error.

[0068] For example, the first mounting portion 321 includes a first boundary surface 3211, and when the boundary structure 312, such as a nozzle, abuts against the first mounting portion 321, one side surface of the nozzle 312 fits against the first boundary surface 3211. For example, the second mounting portion 322 includes a second boundary surface 3221, and when the nozzle 312 abuts against the second mounting portion 322, the other side surface of the nozzle 312 fits against the second boundary surface 3221.It is 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 when the flow distribution body 311 is adjusted for rotation relative to the mounting component 320, the nozzle 312 abuts against the first limiting surface 3211 when in contact with the first mounting portion 321, and the nozzle 312 abuts against the second limiting surface 3221 when in contact with the second mounting portion 322. In this way, not only can the contact stability between the nozzle 312 and the first mounting portion 321 and the second mounting portion 322 be increased, but also the fitting stability can be increased, 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.

[0069] For example, the first boundary surface 3211 is connected to a side surface of the first mounting portion 321 and is inclined. The second boundary surface 3221 is connected to a side surface of the second mounting portion 322 and is inclined. For example, an inclination between the first boundary surface 3211 and the first mounting portion 321 is the same as an inclination between the second boundary surface 3221 and the second mounting portion 322.

[0070] The first mounting portion 321 includes a first side surface and a second side surface arranged opposite each other along a width direction of the first mounting portion 321, wherein the first boundary surface 3211 is connected to the first side surface and inclined. The first mounting portion 321 further includes a first end surface connecting the first side surface and the second side surface, wherein the first end surface is spaced apart from the second mounting portion 322. For example, the first boundary surface 3211 is spaced apart from the second side surface and the first end surface.

[0071] The second mounting portion 322 includes a third side surface and a fourth side surface arranged opposite each other along a width direction of the second mounting portion 322, wherein the second limiting surface 3221 is connected to the third side surface and is inclined. The second mounting portion 322 further includes a second end surface connecting the third side surface and the fourth side surface, wherein the second end surface is distant from the first mounting portion 321. For example, the second limiting surface 3221 is spaced apart from the third side surface and the second end surface. The first side surface is closer to the outlet 314 than the second side surface, and the third side surface is closer to the outlet 314 than the fourth side surface.

[0072] The first boundary surface 3211 and the second boundary surface 3221 are arranged to be inclined relative to each other, and a distance between the first boundary surface 3211 and the second boundary surface 3221 gradually changes along the width direction of the mounting component 320. For example, the distance between the first boundary surface 3211 and the second boundary surface 3221 gradually increases along a direction from the inlet 313 to the outlet 314. It can also be understood that the distance between the first boundary surface 3211 and the second boundary surface 3221 gradually decreases from the first side surface to the second side surface along the width direction of the mounting component 320. In other words, the distance between the first boundary surface 3211 and the second boundary surface 3221 gradually decreases from the third side surface to the fourth side surface along the width direction of the fastening member 320.So that the first boundary surface 3211 and the second boundary surface 3221 have the shape of a “. ". The width direction of the mounting component 320 can be understood as the width direction of the flow distribution assembly 300.

[0073] For example, the shape of the first boundary surface 3211 is substantially the same as the shape of the second boundary surface 3221. For example, the first boundary surface 3211 and the second boundary surface 3221 are both rectangular. For example, the size of the first boundary surface 3211 is substantially equal to the size of the second boundary surface 3221.

[0074] For example, 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 each other. An outer peripheral surface of the flow distribution body 310 is adapted to the first arcuate surface 3212 and the second arcuate surface 3222, thereby making the connection between the flow distribution component 300 and the mounting component 320 more compact and stable.

[0075] For example, the first mounting portion 321 and the second mounting portion 322 are arranged symmetrically to the middle mounting portion 323.

[0076] In practical applications, with an adjusted flow distribution component 310, it may easily occur that the flow distribution component 310 experiences a displacement change relative to the mounting component 320 due to the flow of the medium or other external factors. It should be understood that the displacement change defined in the present application is a rotation change caused by the flow distribution component 310 relative to the mounting component 320. Therefore, the flow distribution assembly 300 of the present application further includes a positioning component 330 that interconnects the mounting component 320 and the flow distribution component 310 to limit the rotation of the flow distribution component 310 relative to the mounting component 310.

[0077] It should be noted that the positioning component 330 is connected to the mounting component 320 and the flow distribution component 310 after the flow distribution component 310 is adjusted to a suitable position.

[0078] For example, 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 spaced at intervals along the rotation direction of the flow distribution component 311. The positioning component 330 can be installed in one of the first positioning grooves 326 and one of the second positioning grooves 317 to limit the rotation of the flow distribution component 310 relative to the mounting component 320.

[0079] For example, the mounting component 320 is provided with two first positioning grooves 326, wherein 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 in the first mounting portion 321 and the first positioning groove 326 in the second mounting portion 322 are opposite to each other.

[0080] It should be noted that in the positioning component 330 in the present application, the manner of positioning between the flow distribution component 310 and the mounting component 320 is not limited thereto. The embodiments of the present application do not limit how the positioning component 330 realizes the positioning between the flow distribution component 310 and the mounting component 320.

[0081] For example, 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 support body of the battery tray by the first detachable structure 325. For example, both the first mounting portion 321 and the second mounting portion 322 are provided with the first detachable structure 325.

[0082] For example, the first removable structure 325 is arranged on a side of the first mounting portion 321 and the second mounting portion 322 that is remote from the flow distribution component 310.

[0083] It should be noted that the flow distribution component 310 of the present application is further detachably connected to the rotating shaft 340 and the mounting component 320. Therefore, the flow distribution component 310 can be installed with appropriate specifications on the rotating shaft 340 and the mounting component 320 according to requirements. In some cases, the mounting components 320 of a plurality of flow distribution assemblies 300 have the same shape, and the flow guide hole 315 of each flow distribution component 310 of the plurality of flow distribution assemblies 300 has the same size; that is, the shapes of the plurality of flow distribution components 310 are the same.

[0084] In other cases, the mounting components 320 of the plurality of flow distribution assemblies 300 have the same shape, while the flow guide hole 315 of each flow distribution component 310 of the plurality of flow distribution assemblies 300 has different sizes. Therefore, 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 with different specifications to change the flow rate of the medium distributed by the flow distribution component 310.

[0085] In other cases, the mounting components 320 of the plurality of flow distribution assemblies 300 have the same shape, while the number of flow guide holes 315 of each flow distribution component 310 of the plurality of flow distribution assemblies 300 is different. Therefore, 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 with different specifications to change the flow rate of the medium distributed by the flow distribution component 310.

[0086] Regarding the different sizes or number of flow guide holes 315 of each flow distribution component 310, reference can be made to the Fig. 1 to Fig. 5, which are not described repeatedly here.

[0087] As in Fig. 12 and Fig. As shown in Figure 13, the battery tray 30 includes a tray body 400 and a plurality of flow distribution assemblies 300. The flow distribution assemblies 300 are detachably connected to the tray body 400. Therefore, the number and installation positions of the flow distribution assemblies 300 installed on the tray body 400 can be selected according to actual needs. Fig. 12 schematically shows an installation relationship between a flow distribution assembly 300, the mounting components of the plurality of flow distribution assemblies 300, and the support body 400. Fig. 12 is an exemplary diagram, and the Fig. The number of flow distribution assemblies 300 shown in Figure 12 does not represent a limitation on the number of flow distribution assemblies 300 of the present application.

[0088] With regard to the plurality of flow distribution assemblies 300, reference may be made to Fig. 6 to Fig. 11, which will not be described repeatedly here. It should be understood that the detachable connection between the flow distribution assembly 300 and the support body 400 can be understood as two parts. In particular, the mounting component 320 of the flow distribution assembly 300 and the support body 400 are detachably connected to each other, and the flow distribution component 310 and the mounting component 320 are detachably connected to each other.

[0089] It should be noted that the mounting component 320 and the flow distribution component 310 of each flow distribution assembly 300 do not necessarily have to be installed together on the support body 400. For example, the mounting component 320 of some flow distribution assemblies 300 is installed on the support body 400, while the flow distribution components 310 are not installed on the support body 400. In another example, the mounting portions 320 and the flow distribution assemblies 310 of all flow distribution assemblies 300 are attached to the support body 400.

[0090] For example, the shapes and sizes of the plurality of mounting components 320 of the battery tray 30 are substantially the same, which facilitates processing and molding. For example, the contours of the plurality of flow distribution components 310 are substantially the same, which facilitates processing and molding. In an optional embodiment, the media distribution capabilities of the plurality of flow distribution components 310 are substantially the same, e.g., the sizes of the flow guide holes 315 of the plurality of flow distribution components 310 are substantially the same, and the number of flow guide holes 315 is substantially the same. In other optional embodiments, the flow guide holes 315 of at least two of the plurality of flow distribution components 310 have different sizes, such as different hole diameters. For specific examples, reference is made to the Fig. 1 to Fig. 5, which will not be described repeatedly here. In other optional embodiments, at least two of the plurality of flow distribution components 310 have a different number of flow guide holes 315. For specific examples, reference is made to the Fig. 1 to Fig. 5, which are not described repeatedly here.

[0091] The battery carrier 30 has a longitudinal direction D3 and a width direction D4, and the longitudinal direction D3 and the width direction D4 are substantially perpendicular to each other.

[0092] An overall structure of the support body 400 of the present application is similar to an overall structure of the support body 200. For example, the support body 400 is provided with a flow guide channel 401, a plurality of battery compartments 402, and a plurality of mounting holes 403. The plurality of battery compartments 402 communicate with the plurality of mounting holes 403, and a battery compartment 402 communicates with at least one mounting hole 403. In the present application, a battery compartment 402 and a mounting hole 403 are considered as an example of a connection. The flow guide channel 401 communicates with the plurality of mounting holes 403. The plurality of mounting holes 403 communicate with the flow guide channel 401 and the plurality of battery compartments 402.It is understood that when the mounting holes 403 are not installed with the flow distribution assembly 300, the flow guide channel 401 directly communicates with the plurality of battery compartments 402 through the plurality of mounting holes 403.

[0093] The plurality of battery compartments 402 can be divided into two groups, with one group arranged on one side of the flow guide channel 403 and the other group arranged on the other side of the flow guide channel 403. One group of battery compartments 402, the flow guide channel 403, and the other group of battery compartments 402 are arranged one behind the other in the width direction D4 of the battery tray 30. There are a plurality of battery compartments 402 on both sides of the flow guide channel 403, and the plurality of battery compartments 402 on the same side of the flow guide channel 403 are arranged sequentially at intervals along the longitudinal direction D3 of the battery tray 30.

[0094] The support body 400 includes a flow guide plate 410, a bottom plate 420, a side plate 430, and a plurality of partition plates 440. The flow guide plate 410, the side plate 430, and the partition plates 440 are all connected to the same surface of the bottom plate 420 to collectively define the plurality of battery compartments 402. The flow guide plate 410, the side plate 430, and the bottom plate 420 together form the flow guide channel 401. The plurality of mounting holes 403 are all formed on the flow guide plate 410.

[0095] For example, the side plate 430 is connected to the peripheral edges of the bottom plate 420, and the plurality of partition plates 440 and the flow guide plate 410 are surrounded by the side plate 430. For example, the side plate 430 may surround and form a cuboid-shaped space. One end of the plurality of partition plates 440 is connected to an inner surface of the side plate 430, and the other end of the plurality of partition plates 440 is connected to the flow guide plate 410.

[0096] For example, there are two flow guide plates 410 spaced apart from each other. The two flow guide plates 410 are spaced apart from each other by the flow guide channel 401. One end of the two flow guide plates 410 is connected to an inner surface of one side of the side plate 430, and the other end of the two flow guide plates 410 is connected to an inner surface of the other side of the side plate 430.

[0097] The plurality of partition plates 440 can be divided into two groups, where one group of partition plates 440 corresponds to one group of battery compartments 402. One battery compartment 402 is spaced between two adjacent partition plates 440 in a group of partition plates 440, and two battery compartments 402 are formed between two partition plates 440 in a group of partition plates 440 and two sides of the side plate 430.

[0098] Each flow guide plate 410 is provided with a plurality of mounting holes 403, and each mounting hole 403 can directly communicate with a battery compartment 402 and the flow guide channel 401. For example, the number of mounting holes 403 formed in the two flow guide plates 410 is the same. For example, the positions of the mounting holes 403 formed in one of the two flow guide plates 410 are opposite to the positions of the mounting holes 403 formed in the other of the two flow guide plates 410. It should be noted that the positions and number of mounting holes 403 formed on each flow guide plate 410 can be adjusted according to actual needs.

[0099] For example, the two flow guide plates 410 are substantially flush with each other at the surfaces remote from the base plate 420.

[0100] For example, the height of the two flow guide plates 410 is not higher than the height of the side plate 430. For example, a side of the two flow guide plates 410 facing away from the bottom plate 420 is substantially flush with a side of the side plate 430 facing away from the bottom plate 420. Another example is that the side of the two flow guide plates 410 facing away from the bottom plate 420 is slightly lower than the side plate 430. In other words, a vertical distance between the two flow guide plates 410 and the bottom plate 420 is not greater than a vertical distance between the side plate 430 and the bottom plate 420.

[0101] The battery tray 400 is further provided with a flow inlet 404 which penetrates the side plate 430 and communicates with the flow guide channel 401.

[0102] The battery tray 200 is further provided with a connector 450. The connector 450 is connected to the side plate 430 and is connected to an outer surface of the side plate 430. The flow inlet 404 penetrates the connector 450 and the side plate 430 and communicates with the flow guide channel 401.

[0103] Each battery compartment 402 can accommodate one cell or one battery component.

[0104] The flow distribution component 310 is configured to distribute the medium introduced into the flow guide channel 401 through its flow guide holes 315 into the connected battery compartment 2402, which is in communication with the flow distribution component 310.

[0105] The flow guide plate 410 is provided with a second detachable structure 411. The first detachable structure 325 and the second detachable structure 411 are detachably connected to each other to establish a detachable connection between the mounting component 320 and the support body 400. In particular, the first detachable structure 325 and the second detachable structure 411 are connected to each other when the mounting component 320 is installed in the mounting hole 403.

[0106] For example, one of the first detachable structure 325 and the second detachable structure 411 includes a connection column, and the other includes a connection slot, and the connection column can be installed in the connection slot. For example, the first detachable structure 325 includes one or more connection columns, and the second detachable structure 411 includes one or more connection slots. The number of connection slots is the same as the number of connection columns. The embodiments of the present application are described using the first detachable structure 325 with two connection columns and the second detachable structure 411 with two connection slots as examples.It is understood that the flow guide plate 410 is provided with a plurality of second removable structures 411, and each second removable structure 411 can be connected to a corresponding first removable structure 325 of a mounting component 320.

[0107] For example, the cross section of the connecting column is an arc-shaped structure, and the shape and size of the connecting slot are adapted to the shape and size of the connecting column. It should be noted that the connecting column and the connecting slot can also take other shapes, which are not limited here.

[0108] For example, an upper end of the connecting column is flush with an upper end of the flow guide plate 410, an upper end of the mounting component 320, and an upper end of the flow distribution body 311. Or in other words, the upper end of the connecting column, the upper end of the flow guide plate 410, the upper end of the mounting component 320, and the upper end of the flow distribution body 311 are substantially flush.

[0109] For example, the sidewall of mounting component 320 is flush with the sidewall of flow guide plate 410. The sidewall of flow guide plate 410 is connected to the top and bottom ends of flow guide plate 410. The sidewall of mounting component 320 is connected to the top and bottom ends of mounting component 320.

[0110] As in Fig. 14 and Fig. 15, a battery carrier 50 includes a carrier body 600 and a plurality of flow distribution components 500. The flow distribution components 500 are removably connected to the carrier body 600, and the flow distribution components 500 are rotatable relative to the carrier body 600. In comparison to the Fig. 12 and Fig. 13, the flow distribution component 500 of the embodiments of the present application can rotate directly relative to the carrier body 600, which is different from the flow distribution component 310 which rotates relative to the mounting component 320, and the mounting component 320 is detachably connected to the carrier body 400.

[0111] The flow distribution component 500 may refer to the flow distribution component 310 and will not be described repeatedly here.

[0112] The difference between the support body 600 and the support body 400 is that the shape of the flow guide plate 610 is different from the shape of the flow guide plate 410. The difference between the support body 600 and the support body 400 is, for example, that the flow guide plate 610 is provided with a rotation shaft 612 at the bottom of its mounting hole 603, the flow distribution component 500 is connected to the rotation shaft 612, and the flow distribution component 500 can rotate about the rotation shaft 612 relative to the flow guide plate 610.

[0113] The difference between the carrier body 600 and the carrier body 400 is that the flow guide plate 610 is provided with third positioning grooves 611 on both side walls of the mounting hole 603. The third positioning groove 611 may refer to the first positioning groove 326 of the mounting component 320 and will not be described repeatedly here. The battery carrier 50 further includes positioning components 700 connected to the flow distribution components 500 and the flow guide plate 610 to limit rotation of the flow distribution components 500 relative to the flow guide plate 610. The positioning component 700 can be installed, for example, in the second positioning groove of the flow distribution component 500 and the third positioning groove 611 on the flow guide plate 610.The positioning component 700 may refer to the positioning component 330 and will not be described repeatedly here.

[0114] The difference between the support body 600 and the support body 400 is, among other things, that the flow guide plate 610 is provided with two boundary surfaces on both side walls of its mounting hole 603. The two boundary surfaces may refer to the first boundary surface 3211 and the second boundary surface 3221 of the mounting component 320, which will not be described repeatedly here.

[0115] The difference between the support body 600 and the support body 400 is, among other things, that the flow guide plate 610 is provided with two opposing arcuate surfaces on both side walls at the position of its mounting hole 603. The two opposing arcuate surfaces may refer to the first arcuate surface 3212 and the second arcuate surface 3222 of the mounting component 320, which will not be described repeatedly here.

[0116] The flow guide channel 601, the flow inlet 604, and the battery compartments 602 of the carrier body 600 may all refer to the carrier body 400 and will not be described repeatedly here.

[0117] The side plates 630, the bottom plate 620, the partition plates 640, and the connector 450 of the support body 600 may all refer to the support body 400 and will not be described repeatedly here.

[0118] It should be noted that two parts of the flow distribution assembly 300 of the present application are implemented separately: the part connected to the support body 400 and the part rotatable relative to the support body 400. Specifically, the flow distribution assembly 300 includes the flow distribution component 310 and the mounting component 320. The battery tray 30 and the battery tray 50 are compared below in connection with practical applications.

[0119] In practical applications, the nozzle 312 of the flow distribution component 310 can be optimized. Since the flow distribution component 310 and the mounting component 320 are detachably connected to each other, the flow distribution component 310 and the mounting component 320 can be connected to each other in a coordinated manner without modifying the support body 400 when structural optimization is required. The structure of the connection between the mounting component 320 and the support body 400 does not need to be modified.

[0120] Since the flow guide plate 610 of the support body 600 is provided with the rotation shaft 612, the rotation shaft 612 can be mounted on the flow guide plate 610 by machining or riveting. However, during transportation and assembly, the rotation shaft 612 is easily damaged or deformed. The rotation shaft 340 is connected to the mounting component 320 and can be manufactured by injection molding. Even if it is damaged, it can be replaced inexpensively, and it is easier to inspect incoming materials, which is beneficial for production.

[0121] Compared to the flow distribution assembly 300, the flow distribution component 500 eliminates the mounting component 320, so that the flow distribution component 500 takes up little space and can be used on more discreet partition walls. QUOTES CONTAINED IN THE DESCRIPTION
