[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this utility model belongs. The terms used in the specification of this utility model are only for the purpose of describing specific embodiments and are not intended to limit this utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0041] The cold plate joint 100 claimed in this application is applied to a battery pack (not shown in the figure) and is used to connect and communicate a first pipe joint (not shown in the figure) and a second pipe joint (not shown in the figure) in the battery pack. The first pipe joint and the second pipe joint are arranged on two adjacent cold plates (not shown in the figure) in the battery pack. That is to say, the cold plate joint 100 is used to connect and communicate two adjacent cold plates in the battery pack.
[0042] As Figures 1 to 3 shown, the cold plate joint 100 provided in an embodiment of this application includes a first joint 10 and a second joint 20. The first joint 10 has a first joint portion 11 and a first plug portion 12 that are in communication with each other. A first sealing ring 101 is sleeved on the first joint portion 11. The first joint portion 11 is used for plugging and mating with the first pipe joint. Moreover, the first joint portion 11 and the first pipe joint are assembled and sealed through the first sealing ring 101. The second joint 20 has a second joint portion 21 and a second plug portion 22 that are in communication with each other. A second sealing ring 102 is sleeved on the second joint portion 21. The second joint portion 21 is used for plugging and mating with the second pipe joint. Moreover, the second joint portion 21 and the second pipe joint are assembled and sealed through the second sealing ring 102. Wherein, the first plug portion 12 can be inserted into the second plug portion 22 and connected and sealed with the second plug portion 22 so that the first joint 10 and the second joint 20 are connected and communicated. Moreover, the insertion depth when the first plug portion 12 is inserted into the second plug portion 22 can be adjusted, and the distance between the first joint portion 11 and the second joint portion 21 can be adjusted.
[0043] As described above, the length of the cold plate joint 100 of the present application can be adjusted by adjusting the insertion depth when the first insertion rod portion 12 is inserted into the second insertion rod portion 22. In this way, the cold plate joint 100 can be adapted to the connection and communication between two cold plates with different spacings, which not only expands the application range of the cold plate joint 100, but also facilitates the operation of the user. In addition, the sealing performance of the cold plate joint 100 for the connection between two adjacent cold plates during assembly is ensured.
[0044] It should be noted that the number of the first sealing rings 101 sleeved on the first joint portion 11 is configured to be multiple. The multiple first sealing rings 101 can simultaneously achieve the assembly seal when the first joint portion 11 is inserted and matched with the first pipe joint, so as to ensure the assembly seal between the first joint portion 11 and the first pipe joint. And, the number of the second sealing rings 102 sleeved on the second joint portion 21 is also configured to be multiple. The multiple second sealing rings 102 can simultaneously achieve the assembly seal when the second joint portion 21 is inserted and matched with the second pipe joint, so as to ensure the assembly seal between the second joint portion 21 and the second pipe joint.
[0045] In the present application, the first joint 10 and / or the second joint 20 are integrally injection-molded from plastic. Preferably, both the first joint 10 and the second joint 20 are integrally injection-molded from plastic material, which is convenient for the production and preparation of the first joint 10 and the second joint 20.
[0046] As Figures 1 to 3 shown, the first joint 10 further has a boss 13, and the boss 13 is arranged at the position between the first joint portion 11 and the first insertion rod portion 12; and, the boss 13 can abut against the second insertion rod portion 22 to limit the insertion depth of the first insertion rod portion 12 in the second insertion rod portion 22, and realize the assembly limit between the first joint 10 and the second joint 20.
[0047] It should be noted that when the cold plate joint 100 assembles the first pipe joint and the second pipe joint on two adjacent cold plates, the second insertion rod portion 22 can be first driven to abut against the boss 13 to make the cold plate joint 100 in the shortest length, and then the first joint portion 11 on the first joint 10 is successively driven to be inserted onto the first pipe joint, and the second joint portion 21 on the second joint 20 is driven to be inserted onto the second pipe joint. During this process, the distance between the first joint portion 11 and the second joint portion 21 can be adjusted by pulling out the first insertion rod portion 12 from the second insertion rod portion 22 until the first joint portion 11 and the first pipe joint, and the second joint portion 21 and the second pipe joint are assembled in place.
[0048] As Figure 1 、 Figure 2As shown, the first joint 10 further has a first hook 14, and the first hook 14 is disposed around the first joint part 11; when the first joint part 11 is inserted and fitted with the first pipe joint, the first hook 14 can be abutted against the first pipe joint to limit the first joint part 11 to the first pipe joint. This can improve the assembly stability of the first joint 10 on the first pipe joint. Here, the number of the first hooks 14 is configured to be two, and the two first hooks 14 are symmetrically arranged. It can be understood that in other embodiments, the number of the first hooks 14 can also be one, three, or even more, and the position of the first hook 14 arranged around the first joint part 11 can be specifically set according to the usage requirements, which will not be elaborated here.
[0049] Similarly, as Figure 1 , Figure 2 shown, the second joint 20 further has a second hook 23, and the second hook 23 is disposed around the second joint part 21; when the second joint part 21 is inserted and fitted with the second pipe joint, the second hook 23 can be abutted against the second pipe joint to limit the second joint part 21 to the second pipe joint. This can improve the assembly stability of the second joint 20 on the second pipe joint. Here, the number of the second hooks 23 is configured to be two, and the two second hooks 23 are symmetrically arranged. It can be understood that in other embodiments, the number of the second hooks 23 can also be one, three, or even more, and the position of the second hook 23 arranged around the second joint part 21 can be specifically set according to the usage requirements, which will not be elaborated here.
[0050] As Figure 2 shown, a third sealing ring 103 is installed in the second plug rod part 22; when the first plug rod part 12 is inserted into the second plug rod part 22, the third sealing ring 103 is compressed and elastically deformed to limit the first plug rod part 12 to the second plug rod part 22. That is to say, by using the elastic deformation of the third sealing ring 103 when it is compressed, on the one hand, the sealing performance of the assembly between the first plug rod part 12 and the second plug rod part 22 can be ensured, and on the other hand, it can also play a role in limiting the assembly between the first plug rod part 12 and the second plug rod part 22. Here, the third sealing ring 103 is assembled into the second plug rod part 22 in an embedded manner.
[0051] Preferably, as Figure 2 shown, the number of the third sealing rings 103 is configured to be multiple, and the multiple third sealing rings 103 are arranged at intervals in the axial direction of the second plug rod part 22, which can further improve the sealing performance and stability of the assembly between the first plug rod part 12 and the second plug rod part 22.
[0052] As Figure 1 , Figure 3As shown, a limit hook 121 is provided on the first plug rod portion 12, and a limit stop 221 is provided on the second plug rod portion 22. A position interference can be formed between the limit hook 121 and the limit stop 221 to limit the separation of the first plug rod portion 12 from the second plug rod portion 22. This can prevent the first joint 10 from detaching from the second joint 20 and integrate the structure of the cold plate joint 100 as a whole.
[0053] Preferably, as Figure 3 shown, a guiding inclined surface 201 is provided on the limit hook 121 and / or the limit stop 221, and the guiding inclined surface 201 can guide the limit hook 121 to pass by the limit stop 221. That is to say, the guiding inclined surface 201 can guide the limit hook 121 to cross over the limit stop 221, which facilitates the assembly of the first joint 10 onto the second joint 20. Here, guiding inclined surfaces 201 are provided on both the limit hook 121 and the limit stop 221, and the two guiding inclined surfaces 201 are in contact with each other, facilitating the arrangement of the limit hook 121 to pass by the limit stop 221.
[0054] As Figure 1 、 Figure 2 shown, an external connecting pipe portion 24 is connected and communicated with the second plug rod portion 22, and the external connecting pipe portion 24 can be used to introduce position coolant; among them, the first joint portion 11 and the second joint portion 21 are communicated with the external connecting pipe portion 24 in parallel. This enables the external coolant to be introduced into the cold plate joint 100 through the external connecting pipe portion 24, and then flow to the two cold plates through the first joint portion 11 and the second joint portion 21. It should be noted that when the first plug rod portion 12 is inserted into the second plug rod portion 22, the first plug rod portion 12 does not block the external connecting pipe portion 24. In this way, it can be ensured that the first joint portion 11 and the second joint portion 21 are communicated with the external connecting pipe portion 24 in parallel.
[0055] The technical features of the above embodiments can be combined arbitrarily. For the sake of brief description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.
[0056] Those of ordinary skill in the art of this technology should recognize that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. As long as appropriate changes and variations are made to the above embodiments within the spirit of the present invention, they fall within the scope of protection required by the present invention.
