Description

Technical Field

[0001] The utility model relates to the field of battery technology, and in particular to a cooling structure. At the same time, the utility model also relates to a battery pack provided with the above cooling structure. Background Art

[0002] With technological advancements, the charge rate of battery packs is gradually increasing, posing a corresponding challenge to the cooling performance of battery pack cooling systems. Existing technologies mostly use dual-sided cooling (side cooling, bottom and top cooling, and cooling of the cell's large surface) to cool the battery cells. The large surface of the cell has the largest heat exchange area and the most significant heat exchange effect on the cell. Cooling the large surface of the cell requires assembling multiple cooling plates, connected by pipes.

[0003] Currently, cold pressing equipment is often used to integrate the cooling plate and piping. This method reduces production line efficiency and prevents effective inspection of the assembled state. Furthermore, if assembly fails due to operational issues, the cold pressing section must be disassembled, which can easily damage the cold plate nozzle, resulting in the cold plate being scrapped and, in turn, increasing the risk of battery pack failure. Utility Model Content

[0004] In view of this, the present invention aims to provide a cooling structure to improve assembly efficiency and reduce the risk of battery pack scrapping.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:

[0006] A cooling structure comprises a liquid infusion pipeline and a liquid cooling plate, and a quick-connect assembly connected between the liquid infusion pipeline and the liquid cooling plate;

[0007] The quick-plug assembly includes an adapter module provided on the liquid cooling plate, and a quick-plug connector with one end plugged into the adapter module, and the other end of the quick-plug connector is plugged into the infusion pipeline.

[0009] Furthermore, the connecting pipe is a bellows.

[0010] Furthermore, the quick-connect connector is L-shaped and has a first connecting section extending along the thickness direction of the liquid cooling plate, and a second connecting section connected to the first connecting section, the second connecting section extending along the height direction of the liquid cooling plate, and the first connecting section is plugged into the adapter module, and the second connecting section is plugged into the connecting pipe.

[0011] Furthermore, the adapter module includes a connecting plate arranged on the liquid cooling plate, and a cylindrical adapter plugged into the connecting plate, and the adapter is provided with a plurality of first elastic snap-in units arranged along its own circumferential spacing on the side facing the liquid cooling plate, and the first connecting section is provided with grooves corresponding to each of the first elastic snap-in units one by one; when the first connecting section is plugged into the adapter, each of the first elastic snap-in units is snapped into the corresponding groove one by one.

[0012] Furthermore, each of the first elastic snap-fitting units includes a guide portion extending axially along the adapter, and a snap-fitting portion connected to the guide portion for snapping into the groove. The snap-fitting portion extends radially along the adapter, and along the axial direction of the adapter, the guide portion is gradually inclined toward the central axis of the adapter at one end away from the adapter.

[0013] Furthermore, a positioning block is provided on a side of the adapter facing the first connecting section, a positioning groove is provided on the first connecting section, and the positioning block is inserted into the positioning groove.

[0014] Furthermore, a limiting ring is provided on the first connecting section, and the limiting ring is used to limit the position of the first connecting section inserted into the adapter, and the positioning groove is provided on the limiting ring.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] The cooling structure described in the present invention, through the arrangement of the adapter module and the quick-plug connector in the quick-plug assembly, can not only connect the quick-plug connector to the infusion line through plugging, thereby realizing convenient disassembly and assembly of the infusion line and improving assembly efficiency, but also can realize disassembly between the infusion line and the liquid cooling plate by removing the adapter module, thereby avoiding damage to the liquid cooling plate and further helping to reduce the risk of battery pack scrapping.

[0017] Secondly, the liquid infusion route consists of an inlet and outlet pipe, which has a simple structure and is easy to design and implement. At the same time, it can ensure the smooth entry and exit of the working fluid. In addition, the inlet and outlet pipes are connected to the corresponding quick-connect connectors through connecting pipes, facilitating the quick assembly and disassembly of the inlet and outlet pipes. The bellows design facilitates assembly and is flexible, allowing it to move with the liquid cooling plate when the battery cell expands, thus absorbing the expansion and deformation of the battery cell.

[0018] Furthermore, configuring the quick-connect connector in an L-shape can save space in the Y direction.

[0019] Furthermore, the provision of the guide portion and the engaging portion not only ensures stable insertion of the first connecting section but also prevents the first connecting section from dislodging from the adapter. At the same time, the inclined provision of the guide portion facilitates the stability of the engaging groove of the engaging portion. By inserting the positioning block into the positioning groove, the structure is simple and easy to design and implement. It also enables rapid positioning of the first connecting section, thereby ensuring that the second connecting section is in a vertical position, thereby improving assembly efficiency. The provision of a limiting ring prevents malfunctions caused by improper insertion of the first connecting section and reduces the time required to adjust the insertion position of the first connecting section, thereby improving assembly efficiency.

[0023] Moreover, the battery cells are extended and arranged along the length direction of the liquid cooling plate, and each battery cell is arranged along the length direction of the liquid cooling plate, which is beneficial for the liquid cooling plates on both sides of the battery cell thickness direction to cool down the large surface of the battery cell, thereby improving the heat exchange effect.

[0038] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0039] Example 1

[0040] This embodiment relates to a cooling structure that can solve the problems of low assembly efficiency between the liquid cooling plate and the liquid infusion pipeline, and the battery pack being easily scrapped during the disassembly process, thereby improving assembly efficiency and reducing the risk of battery pack scrapping.

[0041] In terms of overall structure, Figures 1 to 4 As shown in FIG, the cooling structure of this embodiment includes an infusion pipeline 1 and a liquid cooling plate 2, and a quick-connect assembly 3 connected between the infusion pipeline 1 and the liquid cooling plate 2. The quick-connect assembly 3 includes an adapter module 31 provided on the liquid cooling plate 2, and a quick-connect connector 32 having one end plugged into the adapter module 31, and the other end of the quick-connect connector 32 plugged into the infusion pipeline 1.

[0042] At this time, as set above, through the setting of the adapter module 31 and the quick plug connector 32 in the quick plug assembly 3, not only can the quick plug connector 32 be connected to the infusion line 1 through plugging, the infusion line 1 can be conveniently disassembled and assembled, thereby improving the assembly efficiency, but also the infusion line 1 and the liquid cooling plate 2 can be disassembled by removing the adapter module 31, thereby avoiding damage to the liquid cooling plate 2, and further helping to reduce the risk of battery pack scrapping.

[0043] In practice, the adapter module 31 can be pre-installed on the liquid cooling plate 2 by snap-fitting, and one end of the quick-connect connector 32 is plugged into the adapter module 31, while the other end of the quick-connect connector 32 is plugged into the infusion line 1. This completes the assembly without the use of any other equipment. Of course, in addition to snap-fitting, other common connection methods can also be used between the adapter module 31 and the liquid cooling plate 2.

[0044] At the same time, when plugging in, use special tools to destroy the adapter module 31, so that the position where the adapter module 31 is connected to the liquid cooling plate 2 is deformed, thereby detaching the liquid cooling plate 2, and the disassembly between the infusion pipeline 1 and the liquid cooling plate 2 can be completed. Subsequently, a new adapter module 31 can be replaced for continued use, avoiding damage to the liquid cooling plate 2 during the disassembly process.

[0045] Based on the above overall introduction, in this embodiment, as a preferred implementation form, as Figure 1 and Figure 2 As shown, multiple liquid cooling plates 2 are arranged at intervals along their thickness, and each liquid cooling plate 2 is equipped with two quick-connect assemblies 3 spaced apart along its length. Furthermore, the liquid infusion line 1 includes an inlet pipe 11 and an outlet pipe 12 corresponding to the two quick-connect assemblies 3, respectively. The inlet pipe 11 and the outlet pipe 12 are connected to the corresponding quick-connect connector 32 via a connecting pipe 13.

[0046] As can be appreciated, the infusion circuit 1, consisting of an inlet tube 11 and an outlet tube 12, has a simple structure and is easy to design and implement, while also ensuring smooth inflow and outflow of the working fluid. Furthermore, the inlet tube 11 and the outlet tube 12 are each connected to a corresponding quick-connect connector 32 via a connecting tube 13, facilitating quick assembly and disassembly of the inlet tube 11 and the outlet tube 12.

[0047] In the specific structure, one end of the connecting pipe 13 is plugged into the quick connector 32, and the other end of the connecting pipe 13 is plugged into the liquid inlet pipe 11 or the liquid outlet pipe 12. This arrangement facilitates the disassembly and assembly of the connecting pipe 13, thereby facilitating the maintenance and replacement of the connecting pipe 13.

[0048] Of course, in addition to the plug-in connection form, other common connection forms can also be used between the connecting pipe 13 and the quick-connect connector 32, and between the connecting pipe 13 and the liquid inlet pipe 11 or the liquid outlet pipe 12, as long as the connecting pipe 13 can be easily assembled and disassembled.

[0049] In practice, eleven liquid cooling plates 2 can be provided. Of course, the specific number of liquid cooling plates 2 can be designed and adjusted accordingly based on actual needs, for example, twelve or thirteen. Furthermore, each of the liquid inlet pipe 11 and the liquid outlet pipe 12 in this embodiment corresponds to a quick-connect assembly 3, and the liquid inlet pipes 11 and the liquid outlet pipes 12 can be connected using laser welding.

[0050] It should be understood that the liquid inlet pipe 11 and the liquid outlet pipe 12 are both integrally formed, that is, the liquid inlet pipe 11 and the liquid outlet pipe 12 in this embodiment each correspond to eleven quick-connect assemblies 3, which is also possible. In addition, it should be noted that in this embodiment, the distance between two adjacent liquid cooling plates 2 (i.e., the thickness of the battery cell 41) is greater than 30 mm.

[0051] Furthermore, considering the expansion and deformation of the battery cell 41, in this embodiment, as a preferred implementation, a bellows is used as the connecting pipe 13. This configuration has the advantage of facilitating assembly through the bellows design. Furthermore, the bellows is flexible and can follow the movement of the liquid cooling plate 2 when the battery cell 41 expands, facilitating the absorption of the expansion and deformation of the battery cell 41.

[0052] In addition, in this embodiment, as a preferred implementation form, Figure 3 As shown in the figure, the quick-connect connector 32 is L-shaped and has a first connecting section 321 extending along the thickness direction of the liquid cooling plate 2, and a second connecting section 322 connected to the first connecting section 321. The second connecting section 322 extends along the height direction of the liquid cooling plate 2, and the first connecting section 321 is plugged into the adapter module 31, and the second connecting section 322 is plugged into the connecting pipe 13.

[0053] Here, the quick-connect connector 32 is set to be L-shaped, which can save the space occupied by the quick-connect connector 32 in the Y direction (i.e., the thickness direction of the liquid cooling plate 2), and has a first connecting section 321 plugged into the adapter module 31 and a second connecting section 322 plugged into the connecting pipe 13, which facilitates quick disassembly and assembly between the quick-connect connector 32 and the adapter module 31, and between the quick-connect connector 32 and the connecting pipe 13.

[0054] Specifically, in this embodiment, as a preferred implementation form, still refer to Figure 3 As shown in FIG, the adapter module 31 includes a connection plate 311 provided on the liquid cooling plate 2, and a cylindrical adapter 312 plugged into the connection plate 311. The adapter 312 has a plurality of first elastic snap-fit ​​units 3121 arranged at intervals along its circumference on the side facing the liquid cooling plate 2. The first connecting section 321 has grooves 3211 corresponding to each of the first elastic snap-fit ​​units 3121. Furthermore, when the first connecting section 321 is plugged into the adapter 312, each of the first elastic snap-fit ​​units 3121 snaps into its corresponding groove 3211.

[0055] Here, by providing multiple first elastic snap-in units 3121 on the adapter 312 and the groove 3211 on the first connecting section 321, the elastic tendency of the first elastic snap-in unit 3121 can be utilized to make it snap-in in the groove 3211, thereby achieving the fixation of the first connecting section 321 and further ensuring the connection stability between the first connecting section 321 and the adapter 312.

[0056] In specific implementation, when the first connecting section 321 is plugged into the adapter 312, the first connecting section 321 can push each first elastic snap-in unit 3121 to bend. After the first connecting section 321 and the adapter 312 are completely plugged in, each first elastic snap-in unit 3121 rebounds under the elastic trend and is snapped one by one into the corresponding groove 3211, thereby preventing the first connecting section 321 from falling out of the adapter 312.

[0057] It is worth mentioning that in this embodiment, the number of the first elastic snap-fitting units 3121 is four. Of course, the number can also be designed and adjusted accordingly according to actual needs, for example, it can be set to two or six.

[0058] In addition, a plurality of second elastic snap-in units 3122 are provided on the adapter 312 of this embodiment. The number of the second elastic snap-in units 3122 can be designed and adjusted accordingly according to the actual number of the first elastic snap-in units 3121, that is, one second elastic snap-in unit 3122 is provided between two adjacent first elastic snap-in units 3121, and this embodiment is preferably set to four.

[0059] In the specific structure, each first elastic snap-in unit 3121 and the second elastic snap-in unit 3122 are provided with a bending portion 31213 on the side close to the connecting disk 311. The adapter 312 can be inserted into the connecting disk 311 through each first elastic snap-in unit 3121 and the second elastic snap-in unit 3122, and the adapter 312 can be clamped through each bending portion 31213.

[0060] Furthermore, in this embodiment, as a preferred implementation form, Figure 3 and Figure 4 As shown in the figure, each first elastic snap-fit ​​unit 3121 includes a guide portion 31211 extending axially along the adapter 312, and a snap-fit ​​portion 31212 connected to the guide portion 31211 for snapping into the groove 3211. The snap-fit ​​portion 31212 extends radially along the adapter 312, and along the axial direction of the adapter 312, the end of the guide portion 31211 away from the adapter 312 is gradually inclined toward the central axis of the adapter 312.

[0061] Therefore, by setting the guiding part 31211 and the clamping part 31212, not only can the stable insertion of the first connecting section 321 be guaranteed, but also the first connecting section 321 can be prevented from falling out of the adapter 312. At the same time, the guiding part 31211 is set at an angle, which is conducive to improving the stability of the clamping groove 3211 of the clamping part 31212.

[0062] During specific implementation, when the first connecting section 321 is inserted into the adapter 312 through each guide part 31211, it can push each guide part 31211 to bend, and after being inserted into the adapter 312, each guide part 31211 rebounds under its own elastic tendency, thereby clamping each clamping part 31212 in the corresponding groove 3211 to achieve the fixation of the first connecting section 321.

[0063] In addition, in this embodiment, as a preferred implementation form, Figure 3 As shown in , a positioning block 3123 is provided on one side of the adapter 312 facing the first connecting section 321 , a positioning groove 32121 is provided on the first connecting section 321 , and the positioning block 3123 is inserted into the positioning groove 32121 .

[0064] Here, by inserting the positioning block 3123 into the positioning groove 32121, the structure is simple and easy to design and implement. At the same time, the first connecting section 321 can be quickly positioned, thereby ensuring that the second connecting section 322 is in a vertical state, thereby helping to improve assembly efficiency.

[0065] In specific implementation, when the positioning block 3123 on the adapter 312 close to the liquid inlet pipe 11 is plugged into the positioning groove 32121 on the first connecting section 321, it can ensure that the second connecting section 322 is vertically downward. At the same time, when the positioning block 3123 on the adapter 312 close to the liquid outlet pipe 12 is plugged into the positioning groove 32121 on the first connecting section 321, it can ensure that the second connecting section 322 is vertically upward.

[0066] It should be understood that the positioning blocks 3123 in this embodiment may also be two positioned at intervals along the length direction of the liquid cooling plate 2 . At the same time, the positioning grooves 32121 in this embodiment may also be arranged in a one-to-one correspondence with each positioning block 3123 .

[0067] In addition, as a preferred embodiment, Figure 3 As shown, a limiting ring 3212 is provided on the first connecting section 321 . The limiting ring 3212 is used to limit the position of the first connecting section 321 inserted into the adapter 312 , and a positioning groove 32121 is provided on the limiting ring 3212 .

[0068] Thus, by providing the limiting ring 3212, malfunctions caused by improper insertion of the first connecting section 321 can be avoided, and the time required to adjust the insertion position of the first connecting section 321 can be reduced, thereby improving assembly efficiency. It should be understood that the limiting ring 3212 can also be provided on the second connecting section 322 to limit the position of the second connecting section 322 when inserted into the connecting pipe 13.

[0069] When the cooling structure of this embodiment is in use, the connecting plate 311 can be snapped onto the liquid cooling plate 2, and the adapter 312 can be plugged into the connecting plate 311. Next, the first connecting section 321 of the quick connector 32 can be plugged into the adapter 312, and the second connecting section 322 of the quick connector 32 can be plugged into the connecting pipe 13. At the same time, the liquid inlet pipe 11 and the corresponding connecting pipe 13, as well as the liquid outlet pipe 12 and the corresponding connecting pipe 13, are connected by plugging. This allows for quick assembly of the infusion pipeline 1 and the liquid cooling plate 2, thereby improving assembly efficiency. Furthermore, arranging the second connecting section 322 vertically can reduce the space occupied by the quick connector 32.

[0070] Furthermore, when disassembling the infusion pipeline 1 and the liquid cooling plate 2, the adapter module 31 can be destroyed by using special tools to deform the position where the adapter module 31 is connected to the liquid cooling plate 2, so that the liquid cooling plate 2 can be removed, thereby avoiding damage to the liquid cooling plate 2 during the disassembly process, and further helping to reduce the risk of battery pack scrapping.

[0071] Example 2

[0072] This embodiment relates to a battery pack, which is provided with the cooling structure in the first embodiment.

[0073] The battery pack of this embodiment, by applying the cooling structure of the first embodiment, helps to reduce the assembly space of the quick-connect connector 32, while also helping to improve assembly efficiency and reduce the risk of battery pack being scrapped.

[0074] Among them, as a preferred embodiment, Figure 1 As shown in the figure, the battery pack in this embodiment includes a cell group 4 arranged between two adjacent liquid cooling plates 2. The cell group 4 includes a plurality of cells 41 arranged in sequence along the length direction of the liquid cooling plate 2, and each cell 41 is extended along the length direction of the liquid cooling plate 2.

[0075] Here, the cells 41 are arranged along the length of the liquid cooling plate 2, and each cell 41 is arranged along the length of the liquid cooling plate 2. This facilitates the liquid cooling plate 2 on both sides of the cell 41 to cool the large surface of the cell 41, thereby improving the heat exchange effect. It should be noted that the large surface of the cell 41 in this embodiment refers to the two side surfaces of the cell 41 in the thickness direction.

[0076] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
