[0034] The present invention is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0035] The terms "upper", "lower", "top", "bottom", "inside", "outside" and the like in the embodiments of the present application indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or device referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as a limitation of the present invention. Furthermore, the terms "including", "provided with", "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units inherent to these processes, methods, products or devices.

[0036] In the description of the present application, “plurality” means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0037] In addition to the above, it is still necessary to emphasize that the reference to "embodiment" in this article means that the specific features, structures or characteristics described in conjunction with the embodiment may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0038] like Figure 1 As shown, in the first aspect, the water-cooling plate device provided in the embodiment of the present application can be used to cool a battery. Specifically, the water-cooling plate device comprises: a main board 10 having a chamber inside, two plugs 20 arranged at both ends of the main board 10, and two water pipes 30 for communicating with the chamber; wherein both ends of the main board 10 are bent toward the same side of the main board 10.

[0039] Further, continue to combine Figure 2 As shown, the main board 10 is bent toward the upper side of the main board from the left and right ends of the main body 110 to form two bent parts 120 ( Figure 2 Only one curved portion 120 at the left end is shown in the figure, and the curved portion 120 at the right end is not shown). An opening 123 is provided on each curved portion 120. Each opening 123 is communicated with the chamber.

[0040] The two plugs 20 correspond to the two openings 123 respectively, wherein the plugs 20 are used to seal the corresponding openings 123 so that the chamber is sealed; more specifically, each of the two ends of the main board 10 is connected to a corresponding plug 20, so that the corresponding opening 123 is sealed.

[0041] Two water pipes 30 are respectively connected to the chambers, wherein one water pipe 30 is used for water outlet and the other water pipe 30 is used for water intake. More specifically, the water pipe 30 is hollow inside to form an inner cavity, and the inner cavity is connected to the chamber.

[0042] The two ends of the mainboard 10 are bent toward the same side of the mainboard 10, for example, bent upward as shown in the figure. In this way, when in use, the mainboard 10 can be placed in the upward direction of the opening 123, so as to prevent water or other liquids contained in the mainboard 10 from flowing out, thereby improving the sealing performance of the water cooling plate device and reducing the risk of water leakage.

[0043] In summary, compared with the prior art, the water-cooled plate device can improve the sealing performance of the water-cooled plate device and reduce the risk of water leakage because the two ends of the mainboard 10 are bent toward the same side of the mainboard 10. In some embodiments, the bending angle is 90 degrees.

[0044] In some embodiments, the radius of the bend is less than 12 mm.

[0045] In some embodiments, continued binding Figure 3 As shown, the curved portion 120 includes an arc-shaped transition portion 121 and a bending portion 122, wherein the main portion 110, the arc-shaped transition portion 121 and the bending portion 122 are connected in sequence. Further, the angle between the bending portion 122 and the main portion 110 of the main board is 90 degrees; the main portion 110 here can be understood as the unbent portion of the main board. Further, the radius of the arc-shaped transition portion 121 is less than or equal to 12 millimeters (mm).

[0046] In some embodiments, the mainboard 10 is integrally formed by an extrusion process, which simplifies the processing technology and makes the product lightweight, thereby reducing the product cost. In addition, the flatness can be improved, and a high-quality fit between the product and the heat dissipation pad can be achieved, thereby improving the heat dissipation efficiency.

[0047] In some embodiments, in combination Figure 4 As shown, the connection between the water pipe 30 and the chamber can be achieved in the following manner, that is, the water pipe 30 is directly connected to the main body 110 of the main board 10. In this connection method, a through hole (not shown in the figure) corresponding to the water pipe 30 is provided on the main body 110, and the through hole is connected to the chamber. The end of the water pipe 30 for connecting with the main body 110 covers the through hole, and the inner cavity of the water pipe 30 is connected to the through hole.

[0048] Compared with the above method, Figure 5-7 As shown, the communication between the water pipe 30 and the chamber can also be achieved in the following manner: the water pipe 30 is connected to the plug 20, and is communicated with the chamber through the plug 20. It should be understood that each water pipe 30 is connected to a corresponding plug 20. It should be noted that in this embodiment, a flow channel (not shown in the figure) is provided inside the plug 20 for communicating with the chamber. Correspondingly, the flow channel is communicated with the water pipe 30.

[0049] It should be noted that, compared with the method of connecting the water pipe to the mainboard, the water pipe is connected to the plug and then communicated with the chamber, which can reduce the number of interfaces opened on the mainboard and improve the sealing performance. It can also reduce the amount of welding on the mainboard and avoid clogging of the chamber inside the mainboard.

[0050] In some embodiments, Figure 6As shown, a clamping groove 310 is provided at the end of the water pipe 30 for connecting with the plug 20 , and the water pipe 30 is clamped on the plug 20 through the clamping groove 310 .

[0051] In some embodiments, the end of the plug 20 used for connecting to the water pipe 30 is provided with an outlet (not shown in the figure), and the outlet is connected to the flow channel provided in the plug 20. When the plug 20 is connected to the corresponding water pipe 30, the outlet of the plug 20 is covered by the water pipe 30 and is connected to the inner cavity of the water pipe 30, which can further improve the sealing performance.

[0052] In order to further improve the sealing performance, the water pipe 30 is integrally connected with the corresponding plug 20. In addition, the welding amount can be reduced to avoid blocking the waterway between the water pipe and the plug due to welding.

[0053] In some embodiments, the chamber is divided into a plurality of channels along the length direction of the main board 10. In some embodiments, the two ends of the channel are respectively connected to the two openings 123. That is, the left end of the channel is connected to the opening 123 at the left end of the main board 10, and similarly, the right end of the channel is connected to the opening 123 at the right end of the main board 10.

[0054] In a second aspect, the present application further provides a vehicle, comprising the water cooling plate device described in each embodiment of the first aspect.

[0055] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
