[0038] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0039] like Figures 1 to 4 As shown, the faucet 100 of the embodiment of the present invention includes a faucet body 1, a sealing member 3 and a pressure cover 4. The faucet body 1 is suitable for being connected to the cooling plate 7. The faucet body 1 has a channel 102 connected to the inside and outside of the cooling plate 7. The faucet 100 also has a receiving groove 101 inside, and the receiving groove 101 is connected to the channel 102. The sealing member 3 is arranged in the receiving groove 101, and the sealing member 3 is provided with a through hole 31 connected to the channel 102. The pressure cover 4 is connected to the faucet body 1, and the pressure cover 4 abuts against the seal 3 on the side facing the channel 102.

[0040] Specifically, Figure 1 As shown, the channel 102 includes an inlet and an outlet, the outlet of the channel 102 is connected to the cooling plate 7, the inlet of the channel 102 is connected to the cooling source, the receiving groove 101 is arranged adjacent to the inlet of the channel 102, the outer contour of the cross section of the receiving groove 101 is circular, the receiving groove 101 includes a horizontal annular bottom surface and a vertical cylindrical surface, and the flow area of ​​the receiving groove 101 is greater than the flow area of ​​the channel 102. The depth of the receiving groove 101 is greater than or equal to the thickness of the sealing member 3.

[0041] The seal 3 may be a seal ring, and optionally, the seal ring is a rubber seal ring. For example, the seal ring may be one of EPDM rubber, NBR rubber, silicone rubber, fluororubber or polyurethane rubber. The through hole 31 is located at the center of the seal ring, and the through hole 31 passes through the seal 3, and the flow area of ​​the through hole 31 is greater than or equal to the flow area of ​​the channel 102, so that the smoothness of the cooling medium entering the channel 102 can be improved.

[0042] The faucet body 1 is a metal faucet 100 . For example, the faucet 100 may be an aluminum alloy faucet 100 . Optionally, the faucet 100 is one of 3 series or 6 series aluminum alloys, 3003 or 6061 or 6062.

[0043] The gland 4 is disposed above the faucet body 1 and is located at the inlet side of the channel 102 . The gland 4 is detachably connected to the faucet body 1 , for example, the gland 4 is connected to the faucet body 1 by bolts, bonding or clamping.

[0044] When the gland 4 is connected to the faucet body 1, the lower end surface of the gland 4 abuts against the upper end surface of the seal 3. A hole is also provided in the center of the gland 4, which penetrates the gland 4 and communicates with the channel 102 inside the faucet body 1 and the through hole 31 on the seal 3.

[0045] In the faucet 100 of the embodiment of the present invention, the sealing member 3 is arranged in the receiving groove 101 inside the faucet 100. Compared with the related art in which the sealing ring is arranged outside the faucet 100, the oxidation rate of the sealing member 3 can be reduced, and the sealing member 3 is pressed and fixed in the receiving groove 101 by the gland 4, reducing the risk of the sealing member 3 being misplaced, thereby improving the sealing performance of the faucet 100. In addition, the gland 4 can also reduce the contact area between the sealing member 3 and the outside world, further reducing the oxidation rate of the sealing member 3.

[0046] In some embodiments, a first clamping portion 41 is provided on the gland 4, and a second clamping portion 11 is provided on the faucet body 1. The first clamping portion 41 and the second clamping portion 11 are mutually clamped to connect the gland 4 and the faucet body 1.

[0047] Specifically, Figure 1 and Figure 2 As shown, the pressure cover 4 includes a cover body and a first clamping portion 41, the first clamping portion 41 is located on the outer wall surface of the cover body, for example, the first clamping portion 41 is a buckle, and the outer wall surface of the faucet body 1 is provided with a second clamping portion 11, for example, the second clamping portion 11 is a slot, when the pressure cover 4 is connected to the faucet body 1, the buckle and the slot are clamped to connect the pressure cover 4 to the faucet body 1.

[0048] Alternatively, the first clamping portion 41 is a clamping groove, and the second clamping portion 11 is a buckle; or the first clamping portion 41 is a buckle, and the second clamping portion 11 is an annular protrusion, and the buckle is clamped with the annular protrusion.

[0049] It should be noted that the first clamping portion 41 is integrally formed with the cover body, and the second clamping portion 11 is integrally formed with the faucet body 1 .

[0050] The faucet 100 of the embodiment of the present invention connects the gland 4 to the faucet body 1 by snap-fitting, which not only improves the connection efficiency between the gland 4 and the faucet body 1 but also facilitates the replacement of the seal 3 at a later stage.

[0051] In some embodiments, a protrusion (not shown) is provided on the inner wall surface of the accommodating groove 101 and / or the outer wall surface of the seal 3, the outer wall surface of the seal 3 is in contact with the protrusion, and / or the number of the protrusions is multiple, and the multiple protrusions are arranged at intervals in the height direction of the faucet body 1.

[0052] It should be noted that the protrusion may be provided on the bottom surface of the receiving groove 101 , or the protrusion may be provided on the inner side wall of the receiving groove 101 , or the protrusion may be provided on both the bottom surface and the inner side wall of the receiving groove 101 .

[0053] For example, there are multiple protrusions, and the multiple protrusions are evenly spaced along the circumference of the seal 3 to improve the uniformity of the circumferential extrusion force on the seal 3. The multiple protrusions can also be spaced along the up and down direction, or the multiple protrusions are evenly distributed on the inner wall surface of the receiving groove 101 and the outer wall surface of the seal 3.

[0054] Optionally, the protrusion is integrally formed with the faucet body 1. By providing the protrusion, the seal 3 can be prevented from rotating in the receiving groove 101, and the extrusion force between the seal 3 and the inner wall of the receiving groove 101 can be increased to ensure the compression of the seal 3 and improve the sealing performance of the seal 3.

[0055] Alternatively, the protrusion may also be provided on the outer wall surface of the sealing member 3 , or the outer wall surface of the sealing member 3 and the inner wall surface of the containing groove 101 may both be provided with protrusions.

[0056] When both the outer wall surface of the seal 3 and the inner wall surface of the receiving groove 101 are provided with protrusions, the protrusions on the seal 3 and the protrusions on the receiving groove 101 are arranged at intervals in the circumferential direction of the seal 3, further improving the limiting and squeezing effect on the seal 3.

[0057] In some embodiments, a limiting portion 12 is provided on one side of the faucet body 1 adjacent to the cooling plate 7 , and the limiting portion 12 is suitable for abutting against the cooling plate 7 .

[0058] Specifically, Figure 1 and Figure 2 As shown, the width of the limiting portion 12 is smaller than the width of the faucet body 1, thereby forming a step surface between the limiting portion 12 and the faucet body 1. When the faucet body 1 is connected to the cooling plate 7, the step surface abuts against the cooling plate 7, thereby achieving the limiting between the faucet 100 and the cooling plate 7, and improving the assembly accuracy between the faucet 100 and the cooling plate 7.

[0059] like Figure 5 As shown, the cooling component 200 of an embodiment of the present invention includes a main water pipe 5, a branch water pipe 6 and a water nozzle 100. The main water pipe 5 is suitable for being connected to a cooling source. The water nozzle 100 is the water nozzle 100 of any one of the above-mentioned embodiments. One end of the water nozzle 100 is connected to the branch water pipe 6, and the other end of the water nozzle 100 is suitable for being connected to a cooling plate 7.

[0060] Specifically, Figure 5As shown, the flow area of ​​the main water pipe 5 is larger than the flow area of ​​the branch water pipe 6, the inlet of the main water pipe 5 is connected to the cooling source, and the inlet of the branch water pipe 6 is connected to the outlet of the main water pipe 5. In other words, the cooling medium enters through the main water pipe 5, and then is diverted to the branch water pipe 6, and enters the water nozzle 100 through the branch water pipe 6, and finally enters the cooling plate 7 through the water nozzle 100.

[0061] It should be noted that when the branch water pipe 6 is connected to the faucet 100 , the bottom of the branch water pipe 6 extends into the channel 102 in the faucet 100 . In other words, the branch water pipe 6 passes through the cover plate and the seal 3 in sequence and is inserted into the channel 102 .

[0062] Optionally, the outer diameter of the branch water pipe 6 is smaller than the flow area of ​​the channel 102 , thereby ensuring that the branch water pipe 6 can be inserted into the channel 102 .

[0063] For example, the main water pipe 5 and the branch water pipe 6 are integrally formed, which can improve the sealing between the main water pipe 5 and the branch water pipe 6 and prevent leakage of the cooling medium.

[0064] In the cooling assembly 200 of the embodiment of the present invention, the seal 3 is arranged in the receiving groove 101 inside the faucet 100. Compared with the related art in which the seal ring is arranged outside the faucet 100, the oxidation rate of the seal 3 can be reduced, and the seal 3 is pressed and fixed in the receiving groove 101 by the gland 4, reducing the risk of the seal 3 being misaligned, thereby improving the sealing performance of the faucet 100. Moreover, the gland 4 can also reduce the contact area between the seal 3 and the outside world, further reducing the oxidation rate of the seal 3.

[0065] In some embodiments, there are multiple water faucets 100 and multiple water branch pipes 6 , and the multiple water faucets 100 correspond one-to-one to the multiple water branch pipes 6 .

[0066] Specifically, Figure 5 As shown, multiple branch water pipes 6 are evenly spaced along the length direction of the main water pipe 5, and multiple water nozzles 100 are connected to the multiple branch water pipes 6 one by one. By setting multiple branch water pipes 6 and multiple water nozzles 100, the cooling efficiency of the cooling component 200 can be improved.

[0067] In some embodiments, the main water pipe 5 and the branch water pipe 6 are arranged orthogonally, and / or the outer diameter of the branch water pipe 6 is greater than the inner diameter of the through hole 31 on the sealing member 3 .

[0068] Specifically, Figure 5 As shown, the axis of the branch water pipe 6 is arranged orthogonally to the axis of the main water pipe 5. The orthogonal arrangement of the main water pipe 5 and the branch water pipe 6 can make the circulating medium flow more smoothly in the pipeline and avoid turbulence of the circulating medium in the pipeline.

[0069] The outer diameter of the branch water pipe 6 is larger than the inner diameter of the through hole 31 on the seal 3, which not only ensures that the branch water pipe 6 is in better contact with the seal 3, but also can better squeeze the seal 3, thereby improving the connection stability and sealing between the seal 3 and the branch water pipe 6.

[0070] It should be noted that the flow areas of multiple branch water pipes 6 can be the same or different. When the flow areas of multiple branch water pipes 6 are different, the flow areas of the multiple branch water pipes 6 can gradually increase or decrease along the direction of flow of the cooling medium, or the flow areas of some of the multiple branch water pipes 6 can be the same, and the flow areas of the remaining branch water pipes 6 can be different.

[0071] Arranging the multiple branch water pipes 6 to have different flow areas can adjust the flow resistance of each branch and adjust the flow rate of each branch, thereby improving the thermal management performance of the battery pack.

[0072] In some embodiments, a third clamping portion (not shown) is provided on the main water pipe 5 , and the third clamping portion is connected to the first clamping portion 41 .

[0073] It should be noted that the third clamping part can be a buckle, and the third clamping part is clamped with the first clamping part 41 on the pressure cover 4, or the third clamping part is clamped with the second clamping part 11 on the faucet body 1, which can improve the assembly efficiency and assembly accuracy between the main water pipe 5 and the faucet 100.

[0074] The battery pack of an embodiment of the present invention includes a battery cell group 300, a cooling plate 7, a first cooling assembly 200 and a second cooling assembly 200, the cooling plate 7 is in contact with the battery cell group 300, the first cooling assembly 200 and the second cooling assembly 200 are respectively connected to the inlet and outlet ends of the cooling plate 7, and the first cooling assembly 200 and the second cooling assembly 200 are the cooling assemblies 200 of any of the above-mentioned embodiments.

[0075] Specifically, Figures 6 to 13 As shown, the battery cell group 300 includes a plurality of battery cells, and the plurality of battery cells are arranged in the left-right and front-back directions. The cooling plate 7 is provided on the large surface of the battery cell. It should be noted that the large surface of the battery cell is the side surface with a larger projected area.

[0076] It should be noted that the cooling plate 7 includes two plate bodies, both of which can be stamped plates, or one of the two plate bodies is a flat plate and the other has a stamping pit. The two plate bodies are interlocked to form a closed cavity, and the closed cavity is used to contain the cooling medium. The closed cavity has an inlet and an outlet, and holes are provided at both the inlet and outlet ends. The water nozzle 100 is installed at the position of the hole, and the cooling medium flows in from the water nozzle 100 at the inlet end, passes through the closed cavity, and flows out from the water nozzle 100 at the outlet end.

[0077] The opening of the water nozzle 100 may be oriented toward the length direction of the cooling plate 7, or perpendicular to the large surface of the cooling plate 7, or toward the width direction of the cooling plate 7. It should be noted that the large surface of the cooling plate 7 is the side of the cooling plate 7 with a larger projected area.

[0078] The water nozzle 100 is fixed on the large surface of the cooling plate 7, and a hole is opened on the cooling plate 7. Or the water nozzle 100 is sandwiched between two layers of plates. Or the two layers of plates are inserted into the water nozzle 100, and the two layers of cooling plates 7 are not attached at this position to form a flow channel for the cooling medium to flow.

[0079] In some embodiments, there are multiple battery cell groups 300 and multiple cooling plates 7 , the multiple cooling plates 7 and the multiple battery cell groups 300 are arranged alternately, and the multiple cooling plates 7 correspond to the multiple water nozzles 100 one by one.

[0080] Specifically, Figures 6 to 8 As shown, the battery cell groups 300 are arranged in the left-right direction, the battery cell groups 300 and the cooling plates 7 are arranged alternately in the left-right direction, and each cooling plate 7 corresponds to two water nozzles 100, that is, one water nozzle 100 at the inlet end of the cooling plate 7 and one water nozzle 100 at the outlet end of the cooling plate 7. In other words, the number of water nozzles 100 is twice the number of cooling plates 7. By providing multiple water nozzles 100 and multiple cooling plates 7, the cooling efficiency of the battery pack can be improved.
