DETAILED DESCRIPTION

[0022] The present invention is now further described in conjunction with the accompanying drawings. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0023] like Figure 1 and Figure 2As shown, a cooling pipeline for a battery container energy storage system includes a main pipeline 100, a primary branch 200, a secondary branch 300 and a pipe joint 400. The main pipeline 100 and the primary branch 200, the primary branch 200 and the secondary branch 300, and the secondary branch 300 and the liquid cooling plate are all connected through the pipe joint 400. The pipe joint 400 includes a male joint 410, a female joint 420 and a quick-release assembly 430. The male joint 410 and the female joint 420 are both hollow structures. The upper part of the male joint 410 is inserted into the inner cavity of the female joint 420 and connected through the quick-release assembly 430. The inner cavity of the male joint 410 is connected to the inner cavity of the female joint 420. Through the setting of the pipe joint 400, when installing and removing the pipelines at all levels, it is only necessary to rotate the quick-release assembly 430 and then plug and unplug the male joint 410. The operation is simple, thereby improving the convenience of maintenance and replacement of the cooling pipeline. Specifically, the main pipeline 100 is located below the primary branch 200 , which further facilitates the installation of the cooling pipeline compared to the existing arrangement of the main pipeline 100 above the battery pack, while avoiding the short-circuit effect of the battery pack caused by accidental leakage of coolant in the main pipeline 100 .

[0024] like Figure 1 As shown, the main pipeline 100 includes a main liquid inlet pipeline 110 and a main liquid outlet pipeline 120, the primary branch 200 includes a primary liquid inlet pipeline 210 and a primary liquid outlet pipeline 220, and the secondary branch 300 includes a secondary liquid inlet pipeline 310 and a secondary liquid outlet pipeline 320. The main liquid inlet pipeline 110 and the main liquid outlet pipeline 120 are arranged side by side, and the primary liquid inlet pipeline 210 and the primary liquid outlet pipeline 220 are both multiple and arranged in parallel. The lower end (i.e., the open end) of the primary liquid inlet pipeline 210 is It is connected to the main liquid inlet pipeline 110 through a pipe joint 400, and the lower end (i.e., the open end) of the first-level liquid outlet pipeline 220 is connected to the main liquid outlet pipeline 120 through a pipe joint 400. The second-level liquid inlet pipeline 310 and the second-level liquid outlet pipeline 320 are both multiple and arranged side by side vertically. The right end of the second-level liquid inlet pipeline 310 is connected to the first-level liquid inlet pipeline 210 through a pipe joint 400, and the left end of the second-level liquid outlet pipeline 320 is connected to the first-level liquid outlet pipeline 220 through a pipe joint 400. Specifically, four male connectors 410 are evenly distributed on the total liquid inlet pipeline 110 and the total liquid outlet pipeline 120, and female connectors 420 are correspondingly installed at the lower ends of the first-level liquid inlet pipeline 210 and the first-level liquid outlet pipeline 220; three male connectors 410 are evenly distributed on the first-level liquid inlet pipeline 210 and the first-level liquid outlet pipeline 220, and female connectors 420 are correspondingly installed at the right end of the second-level liquid inlet pipeline 310 and the left end of the second-level liquid outlet pipeline 320; female connectors 420 are installed on the liquid inlet and liquid outlet of the liquid cooling plate, and male connectors 410 are correspondingly installed at the left end of the second-level liquid inlet pipeline 310 and the right end of the second-level liquid outlet pipeline 320.

[0025] It should be noted that the installation of the male connector 410 and the female connector 420 can be swapped according to actual needs, and the installation of the male connector 410 and the female connector 420 on each pipeline can also adopt an integral molding connection.

[0026] like Figure 2 As shown, a step 421 is formed at the lower part of the inner cavity of the female connector 420, and the upper end of the male connector 410 abuts against the step 421. The abutment between the upper end of the male connector 410 and the step 421 plays a positioning role, and avoids the male connector 410 from axial movement.

[0027] like Figure 2-Figure 4 As shown, the quick-release assembly 430 includes a button ring 431, a gear ring 432, a rotating shaft 433, a gear 434, a torsion spring 435 and a clamping block 436. The lower outer wall of the female connector 420 is provided with an annular mounting groove 422. The button ring 431 is rotatably mounted in the mounting groove 422. The gear ring 432 is mounted on the inner ring of the button ring 431. A plurality of radial holes 423 are provided at the lower part of the female connector 420. The mounting groove 422 is connected to the inner cavity of the female connector 420 through the radial holes 423. The shaft 433 is rotatably installed in the radial hole 423, and the gear 434 is mounted on the middle part of the rotating shaft 433. The rim of the gear 434 protrudes from the radial hole 423 near the end of the ring gear 432 and meshes with the ring gear 432. The torsion springs 435 are respectively installed at both ends of the rotating shaft 433, and the clamping block 436 is installed on the rim of the gear 434. The end of the clamping block 436 away from the gear 434 protrudes from the radial hole 423 and is inserted into the annular clamping groove 411 opened at the upper part of the male connector 410. During installation, the button ring 431 is rotated, and the rotation of the button ring 431 drives the gears 434 to rotate synchronously through the gear ring 432. The rotation of the gear 434 allows the block 436 to completely enter the radial hole 423, and then the upper end of the male connector 410 is inserted into the inner cavity of the female connector 420 until it contacts the step 421. Finally, the button ring 431 is released, and the gear 434 is reversely rotated under the action of the torsion spring 435 until the block 436 extends out of the radial hole 423 away from the end of the gear 434 and is inserted into the annular groove 411. During disassembly, the button ring 431 is rotated to allow the block 436 to completely enter the radial hole 423, and then the upper end of the male connector 410 is pulled out of the inner cavity of the female connector 420. Specifically, in order to facilitate the rotation of the button ring 431, the outer ring of the button ring 431 is provided with a plurality of anti-slip ridges 437.

[0028] like Figure 2 As shown, a plurality of sealing rings 500 are provided between the male connector 410 and the female connector 420, and the sealing rings 500 are located above the quick-install assembly 430. By arranging the sealing rings 500 above the quick-install assembly 430, the sealing of the connection between the male connector 410 and the female connector 420 is ensured, thereby ensuring the sealing of the cooling pipeline.

[0029] The flow path of the coolant is as follows: main liquid inlet pipeline 110 → primary liquid inlet pipeline 210 → secondary liquid inlet pipeline 310 → liquid cooling plate → secondary liquid outlet pipeline 320 → primary liquid outlet pipeline 220 → main liquid outlet pipeline 120 .

[0030] The above-mentioned implementation mode is only for illustrating the technical concept and features of the utility model, and its purpose is to enable people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
