DETAILED DESCRIPTION

[0054] Embodiments of the present application are described in detail below with reference to the accompanying drawings, in which like or similar elements or features are denoted by the same or similar reference signs, and examples of the embodiments are described in detail below with reference to the accompanying drawings, in which like or similar elements or features are denoted by the same or similar reference signs. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0055] A battery device 101 according to embodiments of the present application is described below with reference to FIGS. 1-12.

[0056] Referring to FIG. 8, the battery device 101 according to the first aspect embodiment of the present application includes a device housing 10, at least one battery module 21, and a first turbulence structure 31. The first turbulence structure 31 is arranged in the device housing 10 and is arranged on at least one side of the battery module 21, and the first turbulence structure 31 can perform turbulence on the heat exchange medium. For example, the device housing 10 is formed with a liquid inlet 11 and a liquid outlet 12 for the heat exchange medium to enter and exit, and the liquid heat exchange medium of the battery device 101 can enter the device housing 10 from the liquid inlet 11. After the heat exchange medium entering the device housing 10 exchanges heat with the battery module 21, it can flow out from the liquid outlet 12, thereby achieving temperature regulation of the battery module 21.

[0057] Optionally, the battery device 101 can further include a fixing frame 15 arranged in the device housing 10 for fixing the battery module 21.

[0058] The temperature regulation of the battery module 21 by the heat exchange medium can include cooling of the battery module 21 to avoid excessively high temperature of the battery device 101 during operation. Optionally, the heat exchange medium is a cooling liquid. During operation of the battery device 101, the temperature of the battery module 21 rises, and excessively high temperature can cause the separator to melt and short circuit, and eventually cause explosion, fire and other dangers. By providing the cooling liquid in the battery device 101, the battery module 21 can exchange heat with the cooling liquid during operation, and after the heat is transferred to the cooling liquid, the cooling liquid exits the battery device 101 through the liquid outlet 12. The battery module 21 exchanges heat with the cooling liquid during operation, and continuously dissipates heat, so as to ensure that the operating temperature of the battery device 101 is not excessively high, and the battery is prevented from being dangerous.

[0059] The temperature regulation of the battery module 21 by the heat exchange medium can include cooling of the battery module 21 to avoid excessively high temperature of the battery device 101 during operation. Optionally, the heat exchange medium is a cooling liquid. During operation of the battery device 101, the temperature of the battery module 21 rises, and excessively high temperature can cause the separator to melt and short circuit, and eventually cause explosion, fire and other dangers. By providing the cooling liquid in the battery device 101, the battery module 21 can exchange heat with the cooling liquid during operation, and after the heat is transferred to the cooling liquid, the cooling liquid exits the battery device 101 through the liquid outlet 12. The battery module 21 exchanges heat with the cooling liquid during operation, and continuously dissipates heat, so as to ensure that the operating temperature of the battery device 101 is not excessively high, and the battery is prevented from being dangerous.

[0060] Further, the device housing 10 is provided with a first flow disturbance structure 31. During the flow of the heat exchange medium in the device housing 10, the heat exchange medium directly contacts the first flow disturbance structure 31. The first flow disturbance structure 31 can disturb the flow of the heat exchange medium in the device housing 10, so that the heat exchange medium flowing through the device housing 10 is turbulent flow. Compared with laminar flow of the heat exchange medium, the turbulent flow of the heat exchange medium has higher heat exchange efficiency, faster heat exchange rate, and better heat exchange effect with the battery module 21.

[0061] According to the battery device 101 of the embodiment of the present application, by providing the first flow disturbance structure 31 for disturbing the flow of the heat exchange medium on at least one side of the battery module 21 in the battery device 101, the heat exchange medium can form turbulent flow. Compared with laminar flow, the turbulent flow can enhance the heat exchange effect between the heat exchange medium and the battery module 21, improve the heat exchange efficiency, and thus improve the temperature regulation effect of the battery module 21.

[0062] According to some embodiments of the present application, referring to FIG. 10, the first flow disturbance structure 31 comprises a flow disturbance plate 32 and flow disturbance protrusions 33 arranged on the flow disturbance plate 32, and the flow disturbance protrusions 33 are located on at least one side of the flow disturbance plate 32 along the first direction. Wherein, the flow disturbance protrusions 33 located on at least one side of the flow disturbance plate 32 along the first direction include the following cases: for example, the flow disturbance protrusions 33 are located on one side of the flow disturbance plate 32 along the first direction, or the flow disturbance protrusions 33 are arranged on both sides of the flow disturbance plate 32 along the first direction. By arranging the flow disturbance protrusions 33 on at least one side of the flow disturbance plate 32 along the first direction, the flow disturbance of the first flow disturbance structure 31 can be more sufficient, so that the heat exchange medium forms a turbulent flow and the heat exchange rate is faster.

[0063] Wherein, the flow disturbance protrusions 33 located on the same side of the flow disturbance plate 32 along the first direction can be multiple and arranged at intervals. For example, the flow disturbance protrusions 33 located on the same side of the flow disturbance plate 32 along the first direction can be ten. By arranging multiple flow disturbance protrusions 33 on the same side of the flow disturbance plate 32 along the first direction, the flow disturbance of the first flow disturbance structure 31 to the heat exchange medium can be more sufficient, so that the heat exchange rate of the heat exchange medium is faster.

[0064] By arranging the first flow disturbance structure 31 to comprise a flow disturbance plate 32 and flow disturbance protrusions 33 arranged on the flow disturbance plate 32, the first flow disturbance structure 31 is simple and convenient to manufacture and install. During the process that the heat exchange medium flows through the first flow space 22, the flow disturbance protrusions 33 can realize the flow disturbance effect on the heat exchange medium, so that the heat exchange medium flowing through the first flow space 22 forms a turbulent flow.

[0065] According to some embodiments of the present application, referring to FIG. 3 and FIG. 4, the liquid inlet 11 and the liquid outlet 12 are located on opposite sides of the device housing 10 along the second direction, and the flow disturbance protrusions 33 extend along the second direction. By arranging the liquid inlet 11 and the liquid outlet 12 on opposite sides of the device housing 10 along the second direction, the heat exchange medium can flow naturally in the device housing 10 along the second direction after entering the battery module 100 from the liquid inlet 11, and then leave the battery module 100 from the liquid outlet 12 after fully exchanging heat with the battery module 21. At the same time, by extending the flow disturbance protrusions 33 along the second direction, the flow disturbance protrusions 33 can guide the flow of the heat exchange medium, so that the heat exchange medium can flow through all surfaces and avoid insufficient flow disturbance in local positions to form dead zones. For example, when the heat exchange medium is a cooling liquid, by extending the flow disturbance protrusions 33 along the second direction to guide the flow of the cooling liquid, the cooling liquid can cool all surfaces and avoid local hot spots.

[0066] By arranging the flow disturbance protrusions 33 to extend along the second direction, the heat exchange medium can flow in the device housing 10 along the second direction and pass through the flow disturbance protrusions 33 in sequence, so as to achieve the effect of uniform flow disturbance.

[0067] According to some embodiments of the present application, the spoiler bumps 33 located on the same side of the spoiler plate 32 along the first direction are arranged in multiple rows along a third direction (for example, the e3 direction in the drawings), and the spoiler bumps 33 located on adjacent rows are arranged in the third direction, and the first flow channel 34 extending along the second direction is defined between the spoiler bumps 33 located on adjacent rows along the third direction. The third direction, the second direction and the first direction are perpendicular to each other. By arranging the spoiler bumps 33 located on the same side of the spoiler plate 32 along the first direction in multiple rows along the third direction, the heat exchange medium can flow along the second direction in the first flow space 22 and undergo multiple turbulent flows, so that the turbulent flow is more sufficient and the heat exchange efficiency is better.

[0068] According to some embodiments of the present application, as shown in FIG. 10, the projection of the first flow channel 34 on a first reference surface is a first projection, and the first projection extends in a non-linear manner along the second direction, and the first reference surface is perpendicular to the first direction. By arranging the projection of the first flow channel 34 on the first reference surface to extend in a non-linear manner along the second direction, the heat exchange medium can flow through the first flow channel 34 and change the flow direction and speed multiple times, so that the heat exchange medium can be fully turbulent, and the heat exchange efficiency is better.

[0069] According to some embodiments of the present application, the spoiler bump 33 includes a long strip part 35 and multiple protruding parts 36, the long strip part 35 extends along the second direction, and the multiple protruding parts 36 are connected to at least one side of the long strip part 35 along the third direction. By arranging the multiple protruding parts 36 to be connected to at least one side of the long strip part 35 along the third direction, the heat exchange medium can flow along the long strip part 35 and collide with the protruding parts 36 multiple times, so that the flow direction and speed are changed, the heat exchange medium is fully turbulent, and the heat exchange efficiency is better.

[0070] Among them, the multiple protruding parts 36 located on the same side of the long strip part 35 are arranged in multiple rows along the second direction, and the third direction, the second direction and the first direction are perpendicular to each other. By arranging the multiple protruding parts 36 located on the same side of the long strip part 35 in multiple rows along the second direction, the heat exchange medium can flow along the long strip part 35 and change the flow direction multiple times, so that the heat exchange medium is fully turbulent, and the heat exchange efficiency is better.

[0071] According to some embodiments of the present application, as shown in FIG. 10, the spoiler bump 33 is formed with a second flow channel 37 extending along the second direction. By arranging the second flow channel 37 in the spoiler bump 33, the space in the spoiler bump 33 can be fully utilized to provide more space for the heat exchange medium to flow in the device shell 10, so that more heat exchange medium flows through the device shell 10, and the heat exchange effect is improved.

[0072] For example, the spoiler bumps 33 are located on one side of the spoiler plate 32 along the first direction, or the spoiler bumps 33 are arranged on both sides of the spoiler plate 32 along the first direction.

[0073] According to some embodiments of the present application, referring to FIG. 10, at least one side of the turbulence bump 33 along the third direction is formed with a turbulence hole 38 communicating with the second flow channel 37, the third direction, the second direction and the first direction are perpendicular to each other, for example, the turbulence hole 38 is located at one side of the turbulence bump 33 along the third direction, or the turbulence hole 38 is provided at both sides of the turbulence bump 33 along the third direction. The turbulence hole 38 has the function of turbulence, changes the flow direction of the fluid, and makes the heat exchange effect of the heat exchange medium better. For example, the turbulence hole 38 can be provided at one side of the turbulence bump 33 along the third direction, or at both sides along the third direction.

[0074] According to some embodiments of the present application, the turbulence holes 38 located at the same side of the turbulence bump 33 along the third direction are a plurality of turbulence holes 38 arranged at intervals along the second direction. For example, the turbulence holes 38 located at the same side of the turbulence bump 33 along the third direction can be ten turbulence holes 38 arranged at intervals along the second direction. By arranging the turbulence holes 38 as a plurality of turbulence holes 38 arranged at intervals along the second direction, during the flow of the heat exchange medium along the first flow channel 34 and the second flow channel 37, the turbulence effect can be further enhanced by the action of the turbulence holes 38, the turbulence effect can be increased, the turbulence can be more sufficient, and the heat exchange effect can be improved.

[0075] According to some embodiments of the present application, the turbulence bumps 33 located at the same side of the turbulence plate 32 along the first direction are a plurality of turbulence bumps 33 arranged at intervals along the third direction, and the first flow channel 34 extending along the second direction is defined between adjacent turbulence bumps 33 along the third direction, the third direction, the second direction and the first direction are perpendicular to each other, and the turbulence hole 38 communicates the second flow channel 37 and the first flow channel 34. By connecting the second flow channel 37 and the first flow channel 34 through the turbulence hole 38, the first turbulence structure 31 can be completely communicated along the third direction, the heat exchange medium has more flow direction options, the turbulence is more sufficient, and the heat exchange efficiency is higher.

[0076] According to some embodiments of the present application, referring to FIG. 9, the projection of the turbulence plate 32 on the second reference surface is a second projection, the second projection extends in a polyline shape, and the second reference surface is parallel to the first direction. By setting the projection of the turbulence plate 32 on the second reference surface as a polyline shape, the contact area of the turbulence plate 32 and the heat exchange medium can be increased under the condition that the size of the device shell 10 in the third direction is constant, the heat exchange efficiency and the heat exchange effect can be improved, and by extending the turbulence plate 32 in a polyline shape, the turbulence plate 32 itself also has a turbulence effect under the turbulence effect of the turbulence bump 33, the turbulence area is increased, the turbulence effect and the turbulence effect of the first turbulence structure 31 are further improved, the turbulence is more sufficient, and the heat exchange effect is better.

[0077] According to some embodiments of the present application, referring to FIG. 4 and FIG. 8, the liquid inlet 11 and the liquid outlet 12 are located on opposite sides of the device housing 10 along the second direction, and the spoiler 32 extends in a zigzag shape along the third direction, and the third direction, the second direction and the first direction are perpendicular to each other. By making the spoiler 32 extend in a zigzag shape along the third direction, the spoiler 32 can guide the heat exchange medium, and the heat exchange medium entering the first flow space 22 from the liquid inlet 11 can flow naturally along the second direction along the spoiler 32, thereby flowing to the liquid outlet 12. The spoiler 32 guides the heat exchange medium to flow along the second direction through the first flow space 22 completely, avoiding dead angles in the flow, which can cause poor local heat exchange effect of the battery module 21, local temperature difference from the whole, and danger caused by the difference.

[0078] According to some embodiments of the present application, the battery device 101 includes at least two battery modules 21 arranged along the first direction, and a first spoiler structure 31 is arranged between adjacent two battery modules 21. By arranging the first spoiler structure 31 between adjacent two battery modules 21, the heat exchange medium can form turbulent flow when flowing through adjacent two battery modules 21, thereby enhancing the heat exchange effect between the heat exchange medium and the battery module and improving the heat exchange efficiency.

[0079] According to some embodiments of the present application, referring to FIG. 4 and FIG. 8, adjacent two battery modules have a first flow space for the flow of heat exchange medium, the first flow space is provided with a first spoiler structure, and the first flow space 22 is connected to the liquid inlet 11 and the liquid outlet 12. The first flow space 22 can be defined between adjacent two battery modules 21, and the first flow space 22 can also be defined in a temperature adjusting component placed between adjacent two battery modules 21. The heat exchange medium entering the device housing 10 from the liquid inlet 11 can flow through the first flow space 22, and the heat exchange medium can exchange heat with adjacent two battery modules 21 during the process of flowing through the first flow space 22, thereby adjusting the temperature of the battery module 21.

[0080] For example, referring to FIG. 4 and FIG. 8, the battery module 100 includes two battery modules 21, and a first flow space 22 is arranged between the two battery modules 21. The heat exchange medium enters the battery module 100 from the liquid inlet 11, flows through the first flow space 22, exchanges heat with the battery module 21, and then exits the battery module 100 from the liquid outlet 12.

[0081] According to some embodiments of the present application, the first flow disturbance structure 31 is a flexible structure. By making the first flow disturbance structure 31 a flexible structure, when the first flow disturbance structure 31 is installed between two adjacent battery modules 21, the flexible structure can be deformed to make the first flow disturbance structure 31 fit between the two adjacent battery modules 21, and the installation of the first flow disturbance structure 31 can be achieved by being clamped by the two adjacent battery modules 21, so that the installation of the first flow disturbance structure 31 is convenient and no additional assembly components are needed.

[0082] According to some embodiments of the present application, referring to FIGS. 4 and 8, the first flow disturbance structure 31 is in interference fit with the first flow space 22. By making the first flow disturbance structure 31 in interference fit with the first flow space 22, the position of the first flow disturbance structure 31 can be fixed, which facilitates the installation and fixation of the first flow disturbance structure 31, and no additional assembly limiting components are needed.
