Description

Technical Field

[0001] The present application belongs to the technical field of temperature control of energy storage devices, and in particular, relates to a flow regulator and a flow regulation system. Background Art

[0002] For the cooling of energy storage battery packs, in addition to the overall temperature control requirements, in order to avoid relative overheating and accelerated aging of some battery cells, it is also necessary to ensure the balance of the heat dissipation effect of each battery cell. In order to ensure the uniform flow of each branch, throttling devices of different specifications are usually set in each branch at the beginning of the design. The reasonable specifications of pipelines and throttling devices are confirmed through simulation, testing, empirical estimation, etc., and each branch is adjusted to be uniform during the design stage.

[0003] The existing design process is to first confirm the rationality of the overall flow distribution, then confirm the size of the throttling device and the adjacent pipeline connectors, and whether there is dimensional interference, and then proceed to processing and production. If the pipeline is processed in advance during the confirmation process, the throttling device that can achieve the flow distribution effect may not be matched, and waiting for these processes to be completed will extend the processing time and increase the closed-loop time of the overall solution. At the same time, the number of cells in the energy storage system is in the hundreds of thousands, and the batch cost of this adjustment method for installing throttling devices is high. Summary of the invention

[0007] The latch member is suitable for closing the second plug port and is inserted into the pipeline body from the first plug port to reduce the cross-sectional area of ​​the pipeline body for fluid to pass through.

[0008] According to one embodiment of the present application, the latch member includes a plug-in portion located within the pipe body;

[0009] The plug-in portion is provided with a plurality of flow-limiting holes, and the direction in which the flow-limiting holes are provided is consistent with the flow direction of the fluid in the pipeline body.

[0013] According to an embodiment of the present application, the outer diameter of the plug-in portion is the same as the inner diameter of the pipe body, or the outer diameter of the plug-in portion is smaller than the inner diameter of the pipe body.

[0014] According to an embodiment of the present application, the latch member includes a closing portion; the closing portion is disposed on the socket member and closes the second plug port.

[0015] According to one embodiment of the present application, the flow regulator further includes: a waterproof sealing strip;

[0016] The socket piece is provided with a sealing groove, which is arranged around the second plug port; the waterproof sealing strip is suitable for being sandwiched between the inner wall surface of the sealing groove and the closing portion.

[0040] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0041] In the energy storage cell group, the battery management system selects the highest single cell voltage as the charging cut-off voltage during charging, and stops charging when it reaches the voltage. When a cell with a smaller capacity is used in series with a cell with a larger capacity, the cell with a smaller capacity will always be fully charged and discharged, while the cell with a larger capacity will always use part of its capacity, resulting in capacity loss. When the cell with the smallest capacity reaches the end of its life, the entire battery module welded together cannot be used.

[0042] Therefore, in addition to the overall temperature control requirement, the cooling of the energy storage battery pack also needs to ensure the balance of the heat dissipation effect of each battery cell in order to avoid relative overheating and accelerated aging of some battery cells.

[0043] In the current cold plate liquid cooling solution, the branch flow rates are different due to the inconsistent resistance of each branch pipe supplying the coolant. When the cold plate structure is the same, the heat dissipation effect of each battery module varies due to the different coolant flow rates. Therefore, ensuring the uniform coolant flow rate of each branch can improve the balance of the heat dissipation effect of each battery cell.

[0044] In order to ensure the uniformity of the coolant flow in each branch, the relevant technology will adopt two methods:

[0045] Method 1: Carry out flow simulation or testing at the beginning of design. For different energy storage systems, specific pipeline structures and sizes are customized to make the coolant flow distributed to each cold plate consistent during the design stage.

[0046] Method 2: Carry out flow simulation or testing at the beginning of design, and then determine the size of each pipeline according to the flow simulation results. Then install throttling devices in each pipeline, and perform fluid replenishment or throttling according to the flow of each pipeline to ensure the uniformity of flow distribution of each cold plate.

[0047] In the process of implementing the invention, the inventors found that there are at least the following problems in the related art:

[0048] For method 1, the pipeline specifications need to be confirmed under simulation conditions first, and are highly dependent on the designer's experience. If there are too many pipeline specifications, the processing cycle will be longer and the cost will increase. Moreover, if the flow distribution does not meet expectations due to design or installation errors, the entire pipeline needs to be disassembled and replaced for adjustment. The above process is extremely inconvenient.

[0049] For the second method, since the charging and discharging conditions of the energy storage device are stable and predictable, the well-designed pipeline with throttling device does not require additional adjustment during use to ensure the temperature control needs. However, in rare cases, if the branch flow distribution needs to be adjusted due to deviations in design and installation or unexpected failures, the fixed throttling device is extremely inconvenient to disassemble and replace due to its integrated design with the pipeline.

[0050] At the same time, the number of cells in the energy storage system is in the hundreds and thousands, and the batch cost of this adjustment method of installing throttling devices is high. In fact, it is only used in very few cases, and it is difficult for the market to accept it by greatly increasing the batch cost. For the above two methods, the throttling devices need to confirm whether the flow distribution effect meets the standards, whether the total resistance of the pipeline exceeds the capacity of the water pump, whether there is interference in the installation of the throttling device, etc. If the pipeline is processed in advance during the confirmation process, the throttling devices that can achieve the flow distribution effect may not be matched, and the matching throttling devices may have insufficient adjustment capabilities. Waiting for these processes to be completed will extend the design and processing cycle.

[0051] Reference below Figure 1-Figure 8 A flow regulator and a flow regulation system according to embodiments of the present application are described.

[0052] like Figure 1-Figure 3 As shown, the flow regulator can be a part of the pipeline in the energy storage temperature control system, used to provide cooling liquid to the cold plate to cool the energy storage battery pack. The flow regulator includes: a socket part 200 and a latch part 300.

[0053] The socket 200 is used to be connected to the pipe body 100 .

[0054] In actual implementation, a first plug port 110 is opened on the pipeline body 100 . The first plug port 110 is opened above the central axis of the pipeline body 100 , and the opening direction of the first plug port 110 is perpendicular to the flow direction of the fluid in the pipeline body 100 .

[0055] The socket 200 is disposed at the periphery of the first plug port 110 and connected to the pipe body 100 , and the socket 200 is located directly above the first plug port 110 of the pipe body 100 .

[0056] In actual implementation, the socket piece 200 can be integrally formed with the pipe body 100, and the socket piece 200 can also be welded and fixed to the pipe body 100, which is not limited in this embodiment.

[0057] The socket 200 is provided with a second socket 210 which is in communication with the first socket 110 .

[0058] The latch member 300 is suitable for closing the second plug port 210 and is inserted into the fluid in the pipe body 100 from the first plug port 110 to reduce the cross-sectional area of ​​the pipe body for the fluid to pass through.

[0059] Specifically, it can be implemented by at least one of the following implementations.

[0060] First, if Figure 1 As shown, the plug member 300 includes an inserting portion 310 , which is inserted into the pipe body 100 , and a plurality of flow limiting holes 311 are formed on the inserting portion 310 .

[0061] Secondly, the plug member 300 includes an inserting portion 310 , which is inserted into the pipe body 100 , and a flow restriction port (not shown) is formed between the end of the inserting portion 310 and the inner wall surface of the pipe body 100 .

[0062] In both of the above two implementations, the latch member 300 can be inserted into the pipe body 100 to reduce the flow area of ​​the fluid in the pipe body 100 .

[0063] The above-mentioned implementation of the present application can be applied to an energy storage temperature control system, which transports refrigerant to a liquid cooling plate in contact with a battery module through a flow regulator to perform heat exchange and cooling on the battery module. When the fluid flow rate passing through the flow regulator deviates from the expected ideal value, the latch member 300 can be inserted into the pipe body 100 to reduce the cross-sectional area of ​​the pipe body 100 for the fluid to pass through, thereby adjusting the flow rate of the fluid in the flow regulating tube.

[0064] In the solution of the present application, the pipe body 100 and the socket 200 have little effect on the branch flow, while the adjustment and confirmation of the pin 200 that affects the distribution of the pipeline flow can be carried out simultaneously with the pipeline processing. This shortens the design and processing cycle, and at the same time, compared with the method of adding a large number of throttling parts (control valves), the batch cost is lower.

[0065] Furthermore, even if the flow rate of the pipeline changes due to unexpected reasons at a later stage, the flow rate of the fluid in the flow regulating pipe can be adjusted by simply inserting the latch member 300 into the pipeline body 100, without having to replace the entire section of the pipeline to adjust the flow rate.

[0066] like Figure 4 and Figure 5 As shown, in some embodiments, the latch member 300 includes a plug-in portion 310;

[0067] The plug-in portion 310 is suitable for sequentially passing through the second plug-in port 210 and the first plug-in port 110 and being inserted in the pipe body 100 ; a plurality of flow limiting holes 311 are opened on the plug-in portion 310 , and the opening direction of the flow limiting holes 311 is consistent with the flow direction of the fluid in the pipe body 100 .

[0068] In this embodiment, there can be multiple plug members 300, and multiple flow limiting holes 311 are provided on the plug-in portion 310 of each plug member 300, and the total cross-sectional area of ​​the flow limiting holes 311 of each plug member 300 is different. By replacing different plug members 300 to adjust the flow rate, the flow rate adjustment has good adaptability, so that the user can reduce or increase the flow rate according to actual needs to approach the required target flow rate. In actual implementation, the plug-in portion 310 is flat, and the multiple flow limiting holes 311 are distributed in an array on the plug-in portion 310.

[0069] The plurality of flow limiting holes 311 of this embodiment may have different structural designs, so that the plug-in portion 310 of the latch member 300 may have at least one of the following structural forms:

[0070] First, the flow limiting holes 311 are regular hexagonal holes, and the flow limiting holes 311 are in a honeycomb array on the plug-in portion 310 .

[0071] Specifically, a honeycomb extension piece 312 is disposed on the plug-in portion 310 , and the honeycomb extension piece 312 is configured to separate the plurality of flow-limiting holes 311 , and to make at least some of the flow-limiting holes 311 regular hexagonal holes.

[0072] In this embodiment, each flow limiting hole 311 separated by the honeycomb extension piece 312 provides a small and regular flow channel for the fluid, which helps to slow down the turbulence and disordered flow of the fluid in the pipeline, so that the fluid maintains a more stable and orderly flow when passing through the flow limiting hole 311, thereby achieving a rectification effect.

[0073] Secondly, the flow limiting holes 311 are circular holes, and the flow limiting holes 311 are arranged in an array on the plug-in portion 310 .

[0074] In this embodiment, the design of the flow limiting hole 311 as a circular hole is relatively simple and can be easily implemented, for example, by traditional drilling and other methods, which can reduce the overall manufacturing cost and processing time.

[0075] Of course, the flow limiting hole 311 may also have other structural shapes, which is not limited in this embodiment.

[0076] In actual implementation, the outer diameter of the plug part 310 is the same as the inner diameter of the pipe body 100, or the outer diameter of the plug part 310 is smaller than the inner diameter of the pipe body 100. In this way, the plug part 310 can be inserted into the pipe body 100 and can better fit the inner wall surface of the pipe body 100.

[0077] In some embodiments, the latch member 300 includes: a first latch member, a second latch member, and a third latch member;

[0078] The total cross-sectional area of ​​the plurality of flow limiting holes 311 of the first latch member is A1, the total cross-sectional area of ​​the plurality of flow limiting holes 311 of the second latch member is A2, and the total cross-sectional area of ​​the plurality of flow limiting holes 311 of the third latch member is A3, and A1, A2 and A3 are an arithmetic progression.

[0079] In this embodiment, the flow rate is adjusted by replacing different latch members 300 (first latch member, second latch member and third latch member) in sequence, and the total cross-sectional area of ​​the flow limiting holes 311 of each latch member 300 forms an arithmetic progression. This design makes the flow rate adjustment progressive, and the user can gradually reduce or increase the flow rate according to actual needs, gradually approaching the required target flow rate, thereby improving the accuracy of the adjustment.

[0080] In actual implementation, the outer diameter of the plug-in portion 310 is the same as the inner diameter of the pipe body 100 , or the outer diameter of the plug-in portion 310 is smaller than the inner diameter of the pipe body 100 .

[0081] like Figure 4 As shown, for example, if the flow limiting hole 311 is a regular hexagonal hole, the distance between the two opposite sides of the flow limiting hole 311 is d, the width of the honeycomb extension 312 is D, and the outer diameter of the plug-in part 310 is R, then when the outer diameter R of the plug-in part 310 remains unchanged, the width D is adjusted to increase or decrease the distance d, so that the total cross-sectional area of ​​the flow limiting hole 311 of each latch member 300 forms an arithmetic progression.

[0082] like Figure 3-Figure 5 As shown, in some embodiments, the latch member 300 includes an inserting portion 310 and a closing portion 320 located on one side of the inserting portion 310 .

[0083] The plug-in portion 310 is suitable for sequentially passing through the second plug-in port 210 and the first plug-in port 110 and being inserted into the pipe body 100 . The closing portion 320 is disposed on the socket member 200 and closes the second plug-in port 210 .

[0084] In this embodiment, the sealing portion 320 is disposed against the socket member 200 to seal the second plug port 210 to prevent fluid from leaking from the second plug port 210 , thereby ensuring the sealing of the pipeline body 100 .

[0085] like Figure 3 As shown, in some embodiments, the flow regulator further includes: a waterproof sealing strip 400;

[0086] The socket piece 200 is provided with a sealing groove, which is arranged around the second plug port 210 ; the waterproof sealing strip 400 is suitable for being sandwiched between the inner wall surface of the sealing groove and the closing portion 320 .

[0087] In this embodiment, the waterproof sealing strip 400 is sandwiched between the inner wall surface of the sealing groove and the closing portion 320 of the latch member 300 , which can effectively prevent the fluid from leaking from the second plug port 210 , further improving the sealing performance of the pipeline body 100 .

[0088] like Figure 6-Figure 8 As shown, in some embodiments, the flow regulator further includes: a locking member 330;

[0089] The socket member 200 is provided with a first mounting hole 220, and the first mounting hole 220 is located at one side of the second plug port 210, and the closing portion 320 is provided with a second mounting hole 321 corresponding to the position of the first mounting hole 220;

[0090] The threaded portion of the locking member 330 is threadedly connected to the second mounting hole 321 .

[0091] In this embodiment, the threaded portion of the locking member 330 is threadedly connected to the second mounting hole 321 of the latch member 300, so that the latch member 300 can be firmly fixed on the socket member 200 to prevent it from loosening or displacement during fluid flow.

[0092] Of course, the present application can also achieve fixation of the socket 200 and the closing portion 320 by means of clamps, buckles, cable ties, etc., and this embodiment is not limited to this.

[0093] The embodiment of the present application also provides a flow regulation system.

[0094] The flow regulating system comprises: a plurality of pipeline bodies 100 and a flow regulator of any of the above embodiments corresponding to the pipeline bodies 100 one by one;

[0095] The starting end of each pipeline body 100 is used to communicate with the end of the refrigerant delivery pipeline, and the end of each pipeline body 100 is connected to a liquid cooling plate.

[0096] In this embodiment, the plug member 300 is inserted into the pipe body 100 with a relatively large flow rate. When the plug-in portion 310 of the plug-in portion 300 is inserted into the pipe body 100, the effective flow area of ​​the pipe body 100 is reduced from the cross-sectional area of ​​the pipe body 100 to the total cross-sectional area of ​​the multiple flow-limiting holes 311 of the plug-in portion 310, which reduces the flow rate in the pipe body 100 to an average level. While the total flow rate remains unchanged, the reduced flow rate will be supplemented to other pipe bodies 100 with a relatively small flow rate, so that the overall flow distribution tends to be uniform.

[0097] If the flow distribution is not ideal due to various reasons during operation, the pin member 300 in the pipe body 100 where the flow rate differs greatly from the average value can be replaced to further reduce the total cross-sectional area of ​​the multiple flow limiting holes 311 of the plug-in part 310, thereby further reducing the flow in the pipe body 100. By performing secondary adjustment, the overall flow distribution tends to be uniform.
