[0081] The plug structure 123 is provided with a water inlet channel 1231 penetrating the end plate 1212, the water inlet channel 1231 being in communication with the inlet 1221a of the flow channel 1221; the flow distributor 13 is arranged in the water inlet channel 1231, and the flow distributor 13 has at least two flow distribution holes 131 to distribute the water flow entering from the water inlet channel 1231 into the flow channel 1221.

[0082] In this embodiment, the battery device 100 can be a battery module or a battery pack, which is not limited herein. Of course, the battery device 100 also includes the battery module or the battery cell 20 arranged in the box 10, and the battery module and the battery cell 20 can refer to the structure discussed above, which is not repeated here.

[0083] Here, the box 10 is a whole structure forming a closed space, and the frame 121 and the water cooling plate 122 as the second part 12 discussed above enclose to form a mounting cavity for mounting and carrying the battery cell 20 or the battery module, so that the water cooling plate 122 can be in direct contact with the battery cell 20 or the battery module to carry away the generated heat for cooling. It can be understood that the box 10 also includes the first part 11, which is a cover plate covering the opening of the mounting cavity in an example. In another example, the first part 11 can also be a hollow structure, which can refer to the structure of the first part 11 discussed above, which is not repeated here.

[0084] In this example, the water cooling plate 122 serves as the bottom structure of the box 10, which directly carries and protects the internal components. That is, the bottom plate structure is combined with the water cooling plate 122 to form an integrated structure, which can make the battery device 100 lightweight, improve the integration, and also reduce the manufacturing cost. In other examples, the box 10 can also include a bottom plate connected with the frame 121 to enclose a cavity, and the water cooling plate 122 is arranged in the cavity and located on the inner surface of the bottom plate.

[0085] Taking the battery device 100 as an example of a square battery, the water-cooled plate 122 is arranged in a rectangular shape, and the frame body 121 is also arranged in a rectangular ring shape, that is, two opposite side frames 1211 form the long side of the box body 10, and two opposite end plates 1212 form the short side of the box body 10. The frame body 121 is used to limit and fix the periphery of the battery module or the battery monomer 20. In an example, the connection between the two side frames 1211 and the two end plates 1212 can be detachable connection or fixed connection, for example, threaded connection or welding, etc. In other examples, the two side frames 1211 and the two end plates 1212 can also be integrally formed, for example, integrally formed by a casting process.

The plug structure 123 refers to a structure for plugging the end of the water-cooled plate 122 facing the end plate 1212. Since the water-cooled plate 122 serves as the bottom of the box body 10, the plug structure 123 is located at the bottom end in the height direction of the end plate 1212, thereby forming a larger mounting cavity space. The plug structure 123 and the end plate 1212 can be detachable connection or welding, or integrally formed, which is not limited here.

[0086] The water-cooled plate 122 is internally formed with a plurality of flow channels 1221. The flow channel 1221 can be a solid plate body with a plurality of holes extending in the length direction of the box body 10, or two plate bodies with a plurality of parallel extending ribs sandwiched therebetween, and the flow channel 1221 is formed between adjacent two ribs, which is not limited here. One end of the water-cooled plate 122 is connected with the plug structure 123, and the connection mode can be plug-in, threaded connection or welding, etc., which is not limited here. After the water-cooled plate 122 is connected with the plug structure 123, the flow channel 1221 is in a closed state, and an inlet 1221a is formed at one end of one flow channel 1221, which facilitates the entry of cooling water into the flow channel 1221. Corresponding to the inlet 1221a of the flow channel 1221, the plug structure 123 is provided with a water inlet channel 1231, which extends along the thickness direction of the plug structure 123, so that the water inlet channel 1231 communicates the flow channel 1221 with the outside, thereby being able to introduce the cooling water from the outside into the flow channel 1221.

[0087] The shunt 13 refers to a structure capable of shunting and dispersing water flow. The shunt 13 has at least two shunt holes 131, for example, two shunt holes 131, three shunt holes 131, or more than three shunt holes 131. The opening shape of the shunt hole 131 is not limited, for example, circular, square, polygonal, etc. The material of the shunt 13 can be the same metal as the material of the end plate 1212, or can be plastic or ceramic, etc., which is not limited here. The shunt 13 can be in the form of a plate, and the shunt hole 131 is a hole in the shunt 13; or the shunt 13 can also be in the form of a mesh, and the shunt hole 131 is a mesh hole, which is not limited here. The shunt 13 is arranged in the water inlet channel 1231, which means that it can be arranged at any position of the water inlet channel 1231, for example, it can be arranged at the opening of the water inlet channel 1231 at both ends, or it can be arranged at any position between the two openings of the water inlet channel 1231. The shunt 13 covers the cross section of the water inlet channel 1231, so that the cooling water flows to the flow channel 1221 through the shunt 13, so as to disperse the water flow into at least two streams.

[0088] In the battery device 100 of the present embodiment, the box body 10 is enclosed by the frame 121 and the water cooling plate 122 to form a mounting cavity for mounting the battery monomer 20 or the battery module, so that the battery and the battery module are water-cooled by the water cooling plate 122. The water cooling plate 122 has a flow channel 1221 extending in the extension direction thereof, and one end plate 1212 has a plug structure 123 at the bottom end thereof. The plug structure 123 is used to block one end of the water cooling plate 122 to form a closed flow channel 1221. The plug structure 123 has a water inlet channel 1231, which is in communication with the inlet 1221a of the flow channel 1221, so as to input cooling water into the flow channel 1221. The shunt 13 is arranged at the water inlet channel 1231. The shunt 13 can be arranged at any position of the water inlet channel 1231, so that the cooling water is shunted by the shunt hole 131 of the shunt 13 after entering, thereby reducing the water flow intensity and reducing the abnormal sound caused by water flow impact.

[0089] Please refer to Figure 5 and Figure 6 In an embodiment of the present application, the axes of the at least two shunt holes 131 are not arranged in parallel, and the axes of the at least two shunt holes 131 are arranged in a diffusion trend towards the flow channel 1221.

[0090] In the example, when the two flow distribution holes 131 are not parallel to each other, the central axes of the two flow distribution holes 131 are inclined to diverge in the direction of the water flow, that is, in the direction of the water flow, the central axis of the upper flow distribution hole 131 is inclined upward, and the central axis of the lower flow distribution hole 131 is inclined downward. When the number of flow distribution holes 131 is greater than two, the central axes of the flow distribution holes 131 are all inclined to diverge, for example, the flow distribution holes 131 in the upper row are all inclined upward, and the flow distribution holes 131 in the lower row are all inclined downward.

[0091] By inclining the central axes of the flow distribution holes 131 to diverge, the direction of the water flow through the flow distribution member 13 can be changed, the water outlet area can be enlarged, and the water flow speed can be reduced, thereby further reducing the abnormal sound caused by the water flow impact.

[0092] Please refer to Figures 5 to 8 In an embodiment of the present application, the surface of the flow distribution member 13 is concave toward the flow channel 1221 to form an arc surface, and the central axis of the flow distribution hole 131 is perpendicular to the arc surface of the flow distribution member 13.

[0093] In the example, the surface of the flow distribution member 13 is concave toward the flow channel 1221 to form an arc surface, that is, the flow distribution member 13 is in the shape of an arc plate. Optionally, in the cross section perpendicular to the surface of the water cooling plate 122, the flow distribution member 13 is in the shape of an arc, for example, a semicircle or a semi-ellipse. In the cross section parallel to the surface of the water cooling plate 122, the flow distribution member 13 is also in the shape of an arc, for example, a semicircle or a semi-ellipse. The central axis of the flow distribution hole 131 is perpendicular to the arc surface of the flow distribution member 13, that is, the central axis of the flow distribution hole 131 is perpendicular to the tangent line of the point through which the central axis passes.

[0094] In this way, the flow distribution member 13 is provided with an arc surface, which can have a better buffering effect on the water flow, and on the basis of ensuring that the central axes of the flow distribution holes 131 diverge, the flow distribution holes 131 are more convenient to process.

[0096] In the example, the flow distribution holes 131 are provided in a plurality of numbers, for example, three or more. The radial distribution means that the flow distribution holes 131 are distributed in a diverging manner around the geometric center of the flow distribution member 13, and the closer the flow distribution hole 131 is to the edge of the flow distribution member 13, the more the central axis of the flow distribution hole 131 is inclined away from the center of the flow distribution member 13, so that the flow distribution member 13 is similar to a shower head structure that inclines to water.

[0097] The shunt 13 of the structure can further increase the water outlet area and improve water outlet uniformity while dispersing a water flow into multiple water flows, thereby further slowing down the flow rate and reducing the abnormal sound.

[0098] In an embodiment of the present application, the opening area of the shunt hole 131 accounts for greater than or equal to 50% and less than or equal to 90% of the surface area of the shunt 13.

[0099] And / or, the aperture of the shunt hole 131 is greater than 0.3mm and less than 3mm.

[0100] In the present example, the opening area of the shunt hole 131 accounts for greater than or equal to 50% and less than or equal to 90% of the surface area of the shunt 13, otherwise the structural strength is low, of course, the opening area of the shunt hole 131 should not be too small, otherwise the water inflow is affected. The proportion range is set to be greater than or equal to 50% and less than or equal to 90%, for example, it can be 60%, 70%, 80%, 90%, etc., thereby meeting the water flow from the water inlet channel 1231 into the flow channel 1221, improving the structural strength, and achieving good shunting effect.

[0101] The aperture of the shunt hole 131 refers to the diameter when the shunt hole 131 is a circular hole. On the basis of limiting or not limiting the proportion of the shunt hole 131, the aperture of the shunt hole 131 is set to be greater than 0.3mm and less than 3mm, for example, it can be 0.4mm, 0.8mm, 1.0mm, 1.2mm, 1.5mm, 1.8mm, 2.0mm, 2.5mm, 2.8mm, etc. The size of the shunt hole 131 can expand the water outlet area and achieve good shunting effect. In other examples, the shunt hole 131 can also be a square hole, at this time, the opening area of the shunt hole 131 can be set according to the area of the circular hole, so that the side length size range can be set.

Of course, in other examples, the plug-in portion 1232 can also be arranged as multiple spaced blocking protrusions, so that one blocking protrusion corresponds to one flow channel 1221. This connection method facilitates the connection of the water-cooled plate 122 and the frame 121. Optionally, the plug structure 123 and the water-cooled plate 122 can be further fixed by threaded connection in this connection mode.

Optionally, the water outlet nozzle 15 is connected at the opening of the other end of the water outlet channel, thereby facilitating connection with external pipelines.

This structure can simplify the structure, reduce the assembly of parts, and improve the connection strength. In other examples, the end plate and the plug structure can also be formed separately, the end plate is provided with an opening, the plug structure forms a water inlet channel, and the plug structure and the end plate are welded or assembled, so that the opening is arranged corresponding to the water inlet channel and communicates with each other.

[0121] The plug structure 123 is provided with a water inlet channel 1231 penetrating the end plate 1212, and the water inlet channel 1231 communicates with the inlet 1221a of the flow channel 1221.
