[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] A water-cooling assembly for a segmented battery pack unit, such as Figures 1-4 As shown, the base plate 1 is tightly mounted on the battery pack segment unit; the water tank 2 is fixed to the base plate 1, and a water cavity is opened inside the water tank 2;

[0028] The flow guiding component is fixed to the water tank 2, and the interior of the flow guiding component is connected to the water cavity to allow water to flow in the water cavity.

[0029] The base plate 1 is tightly mounted on the battery pack segment unit. The base plate 1 has a heat conduction function, which can conduct heat from the surface of the battery pack segment unit. The flow guide component can transfer water or other liquid medium to the water cavity of the water tank 2. The temperature of the liquid medium is low. The heat absorbed by the base plate 1 is transferred to the liquid medium. The liquid medium absorbs heat and quickly and evenly removes the heat from the surface of the battery pack segment unit, thereby improving the heat dissipation efficiency of the battery pack segment unit.

[0030] The flow guiding components are provided in multiple sets, and the multiple sets of flow guiding components are located at both ends of the water tank 2;

[0031] The flow guiding component includes a water tank 7, which is fixedly connected to the water tank 2. The interior of the water tank 7 is connected to the water cavity, and a water outlet 10 is opened at one end of the water tank 7.

[0032] The flow guiding components are installed at both ends of the water tank 2. One end of the flow guiding component is connected to the external water supply source, and the other end of the flow guiding component is connected to the external water outlet pipe 8.

[0033] A water pipe 8 is fixedly connected to one end of the water tank 7. The water pipe 8 is connected to the water outlet 10 for water flow in the water tank 7. A convex ring 9 is fixedly connected to the outer wall of the water pipe 8. The convex ring 9 is located at the end of the water pipe 8 away from the water tank 7.

[0034] The liquid medium flows from one end of the water tank 7 into the water cavity of the water tank 2, and then is discharged from the other end of the water tank 7, so that the liquid medium in the water tank 2 is in a slow flow state, which allows the heat-carrying liquid medium to form a circulating water path, quickly and evenly remove heat, and improve cooling efficiency.

[0035] Multiple sets of flow guiding components, water tank 7 and water pipe 8, are respectively located at both ends of water tank 2 to optimize water flow path and reduce pressure loss.

[0036] The segmented water-cooled components of this battery pack offer better cooling performance and allow for the selection of smaller components, saving space and cost.

[0037] Water pipe 8 can be used to connect to the water outlet 10 of water tank 7, connecting water tank 7 within a certain distance. Water pipe 8 is flexible, easy to bend, and saves space. The convex ring 9 facilitates the connection of the end of water pipe 8 to external pipes.

[0038] A groove 11 is provided on one side of the base plate 1, and the corners of the groove 11 are rounded.

[0039] The groove 11 allows the base plate 1 to fit the shape of the battery pack segment unit, and the rounded corners prevent the base plate 1 from scratching the pipes or pipelines.

[0040] The base plate 1 has multiple sets of circular holes, and screws 3 are installed in each set of circular holes.

[0041] The base plate 1 has multiple sets of protrusions 4 fixed to its side, and each set of protrusions 4 has a hole 5 through which a screw 6 is installed.

[0042] The round hole and screw 3 facilitate the mounting of the base plate 1 onto the battery pack segment unit, while the protrusion 4, hole 5, and screw 6 facilitate the connection between the base plate 1 and the protruding part of the battery pack segment unit.

[0043] The working principle of the water-cooled component for a segmented battery pack unit provided by this utility model is as follows:

[0044] The water pipe 8 at one end of the water tank 7 is connected to the external pipe supplying the liquid medium, and the water pipe 8 at the other end is connected to the external water outlet pipe 8. The liquid medium enters the water tank 7 through the water pipe 8. After entering the water cavity, the bottom plate 1 and the liquid medium absorb the heat from the battery pack segment unit. The liquid medium carrying the heat is discharged from the water tank 7 and the water pipe 8 at the other end, so that the liquid medium circulates and evenly removes the heat from the surface of the battery pack segment unit, resulting in a good cooling effect and improving the heat dissipation efficiency of the battery pack segment unit.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
