[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] It should be noted that the liquid cooling plate 1 is made of high thermal conductivity materials such as copper or aluminum to ensure efficient heat transfer. When the equipment located on the top of the liquid cooling plate 1 generates heat, the generated heat can be effectively transferred to the coolant flowing in the cooling tank 2, and the heat is taken away by the flowing coolant to complete the cooling. There are two connecting pipes 3, both of which are inserted and connected on the top of the liquid cooling plate 1, and one end is located inside the cooling tank 2. When in use, one of the connecting pipes 3 is used to input coolant into the cooling tank 2, and the other connecting pipe 3 is used to discharge the coolant located inside the cooling tank 2. The connector 4 fixedly connected at the other end is used to connect the equipment for transmitting coolant, thereby realizing the input of coolant into the cooling tank 2. Two support blocks 5 are sleeved on the outer wall of each connecting pipe 3, and the two support blocks 5 are sleeved on the outer wall of each connecting pipe 3. The support blocks 5 are spliced into a truncated cone shape, and the two threaded half rings 7 form a circular ring shape in cross section. The outer wall of the threaded half ring 7 is provided with threads, and the nuts provided on the outer walls of the two threaded half rings 7 correspond to each other. The threaded barrel 9 is provided in the shape of a cylinder with threads provided inside. The threads provided in the threaded barrel 9 are adapted to the threads provided on the threaded half rings 7. When it is necessary to fix the position of the support block 5, the two support blocks 5 are sleeved on the outer wall of the connecting pipe 3 through the first connecting groove 6, and the two support blocks 5 are aligned and rotated so that the threaded half ring 7 at the bottom of the support block 5 penetrates into the interior of the threaded barrel 9, and the threaded half ring 7 is fixed to the interior of the threaded barrel 9 through the threads, so that the connection between the connecting pipe 3 and the liquid cooling plate 1 is strengthened by the support block 5 and the threaded half ring 7 to avoid bending damage at the connection between the two due to collision.
[0024] Specifically, the horizontal transverse cross section of the cooling groove 2 is configured to be wavy.
[0025] It should be noted that through the design of the wavy cooling tank 2, it is used to improve the heat transfer efficiency of the liquid cooling plate 1. This design effectively increases the surface area and enhances the contact area between the coolant and the cooling tank 2, thereby accelerating the heat transfer speed.
[0026] Specifically, a plurality of batteries 11 are arranged on the top of the liquid cooling plate 1. A placement rack 10 is fixedly connected to the top end of the liquid cooling plate 1. The batteries 11 are inserted and connected inside the placement rack 10. A housing 12 is fixedly connected to the top of the liquid cooling plate 1, and a top shell 13 is fixedly connected to the top end of the housing 12.
[0027] It should be noted that the batteries 11 provided are lithium batteries. The batteries 11 provided are directly attached to the top of the liquid cooling plate 1. When the batteries 11 generate heat during use, the heat is directly transferred through the liquid cooling plate 1 to the coolant in the cooling tank 2 for cooling. The placement rack 10 provided is used to limit the positions of the batteries 11. A connecting pipe 3 is inserted and connected to one side of the housing 12, so that the connector 4 at the end of the connecting pipe 3 is located outside the housing 12. During use, the equipment for transporting the coolant is directly connected through the connector 4 located outside the housing 12. The housing 12 and the top shell 13 provided are both used to protect the batteries 11, and the two are connected by bolts. When assembling the batteries 11 and maintaining the batteries 11, first open the top shell 13. After assembling and maintaining the batteries 11, fix the top shell 13 on the top of the housing 12 through bolts.
[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
