[0034] The following is for reference. Figures 1-2 The cooling plate 100 according to the embodiment of the present utility model has a simple structure, can improve the heat dissipation efficiency of the coolant, thereby improving the cooling effect of the cooling plate 100, ensuring the reliability of the cooling plate 100, and is flexible in use to meet different usage needs.

[0035] like Figures 1-2 As shown, a cooling plate 100 according to an embodiment of the present invention includes: a main housing 1, at least one turbulence fan blade 2, and a drive member.

[0036] A cooling chamber 13 is formed inside the main housing 1. The main housing 1 is provided with an inlet 11 and an outlet 12 communicating with the cooling chamber 13. The turbulence fan blade 2 is rotatably installed in the cooling chamber 13. At least part of the medium entering through the inlet 11 flows to the outlet 12 after passing through the turbulence fan blade 2. The driving member is selectively powered to the turbulence fan blade 2. The driving member is used to drive the turbulence fan blade 2 to rotate in the opposite direction to the flow direction of the medium. When the turbulence fan blade 2 is disconnected from the driving member, it rotates with the flow direction of the medium.

[0037] The cooling plate 100 is disposed within the battery pack, and the battery pack typically uses the cooling plate 100 for heat dissipation. The cooling plate 100 is part of the liquid cooling system and can directly contact the battery modules of the battery pack, thereby effectively conducting heat and maintaining the battery pack temperature within a safe range. The coolant in the cooling plate 100 can exchange heat with the battery pack through the cooling plate 100, thus achieving efficient thermal management and ensuring the reliability of the battery pack.

[0038] Specifically, the cooling plate 100 is provided with a main shell 1, which is located on the outermost side of the cooling plate 100. The main shell 1 can support and protect the internal structure of the cooling plate 100, ensuring the reliability of the cooling plate 100. A cooling cavity 13 is formed inside the main shell 1. The main shell 1 can be made of aluminum, which can improve the weight of the cooling plate 100 and improve its heat conduction. The main shell 1 is provided with an inlet 11, which is connected to the cooling cavity 13. Coolant can be transported from the outside to the cooling cavity 13 through the inlet 11. The main shell 1 is also provided with an outlet 12, which is also connected to the cooling cavity 13. Coolant that has undergone heat exchange in the cooling cavity 13 can flow out to the outside through the outlet 12 to ensure the reliability of the cooling plate 100.

[0039] Furthermore, the cooling plate 100 is also provided with at least one turbulence fan blade 2, that is, the turbulence fan blade 2 can be set to one, two or three, etc. The turbulence fan blade 2 is set in the cooling cavity 13 and can rotate relative to the cooling cavity 13. When the coolant enters the cooling cavity 13 through the inlet 11, it can flow in the cooling cavity 13. At least part of the coolant can flow to the turbulence fan blade 2, and the turbulence fan blade 2 can rotate relative to the cooling cavity 13, so that when the coolant flows to the turbulence fan blade 2, the turbulence fan blade 2 can rotate to turbulent the coolant, so that the coolant can absorb more heat, thereby improving the heat dissipation efficiency of the coolant and improving the heat exchange effect of the cooling plate 100. The turbulence fan blade 2 is set to at least one, that is, the turbulence fan blade 2 can also be set to multiple. Multiple turbulence fan blades 2 can turbulent the coolant at different positions in the cooling cavity 13, thereby improving the heat dissipation efficiency of the coolant at multiple points in the cooling cavity 13 and ensuring the reliability of the cooling plate 100.

[0040] Furthermore, the cooling plate 100 is also provided with a driving component, which can be a drive motor or the like. The driving component can be located on the outside of the main housing 1 and selectively connected to the turbulence fan blade 2 to selectively drive the turbulence fan blade 2 to rotate. That is, when the driving component is connected to the turbulence fan blade 2, the driving component can drive the turbulence fan blade 2 to rotate relative to the cooling chamber 13, and the rotation direction of the turbulence fan blade 2 can be adjusted by the direction of the driving component. When the driving component is disconnected from the turbulence fan blade 2, the turbulence fan blade 2 can rotate under the action of the coolant.

[0041] Thus, when the driving component is connected to the turbulence fan blade 2, it can drive the turbulence fan blade 2 to rotate, so that the flow direction of the turbulence fan blade 2 and the medium in the cooling chamber 13, i.e., the coolant, is opposite. This allows the turbulence fan blade 2 to turbulently flow the coolant in the cooling chamber 13 as a whole. When the driving component is disconnected from the turbulence fan blade 2, the medium in the cooling chamber 13, i.e., the coolant, can push the turbulence fan blade 2 to rotate when it flows to the turbulence fan blade 2, allowing the turbulence fan blade 2 to turbulently flow the coolant locally. Multiple turbulence fan blades 2 can be provided in the cooling chamber 13, thereby allowing the turbulence fan blade 2 to turbulently flow in multiple places in the cooling chamber 13, increasing the turbulence range, and thus improving the heat dissipation efficiency of the coolant. This improves the cooling effect of the cooling plate 100, ensures the reliability of the cooling plate 100, and provides flexible usage to meet different application needs.

[0042] According to the embodiment of the present invention, the cooling plate 100, by providing at least one turbulence fan blade 2 in the cooling cavity 13, can turbulently flow the coolant in the cooling cavity 13. The structure is simple, allowing the coolant to absorb more heat and improve the heat dissipation efficiency of the coolant, thereby improving the cooling effect of the cooling plate 100 and ensuring the reliability of the cooling plate 100. Furthermore, it is provided with a drive component that is selectively powered to the turbulence fan blade 2, so that the turbulence fan blade 2 can be actively rotated by the drive component or rotated with the medium. The usage is flexible, can meet different usage needs, has better performance, and is applicable to a wider range of applications.

[0043] In some embodiments, the cooling chamber 13 includes an inlet region 131 and an outlet region 132 distributed along a first direction, the inlet port 11 is connected to the inlet region 131 along a second direction, and the outlet port 12 is connected to the outlet region 132 along a second direction, the first direction and the second direction intersect.

[0044] Specifically, a cooling chamber 13 is provided inside the main housing 1, and coolant can flow within the cooling chamber 13, and such Figure 1 As shown, the cooling chamber 13 is provided with an inlet region 131 and an outlet region 132. The inlet port 11 can be connected to the inlet region 131, that is, the coolant entering the cooling chamber 13 through the inlet port 11 can flow into the inlet region 131. The outlet region 132 can be connected to the outlet port 12, that is, the coolant flowing into the outlet region 132 can be discharged to the outside of the cooling chamber 13 through the outlet port 12.

[0045] Furthermore, the inlet region 131 and the outlet region 132 are distributed along the first direction, and the inlet port 11 is connected to the inlet region 131 along the second direction, and the outlet port 12 is connected to the outlet region 132 along the second direction. This allows the coolant to enter the inlet region 131 from the inlet port 11 along the second direction under pressure, and then flow into the outlet region 132 along the first direction to completely fill the cooling cavity 13. This allows all parts of the cooling plate 100 to exchange heat with the outside, improving the heat exchange efficiency. The coolant after heat exchange can flow out of the outlet region 132 along the second direction, ensuring the reliability of the cooling plate 100.

[0046] Furthermore, the first direction and the second direction intersect, that is, the first direction and the second direction can be set to be perpendicular, etc. The flow direction of the coolant into the cooling chamber 13 and out of the cooling chamber 13 is different from the flow direction of the coolant between the inlet region 131 and the outlet region 132, thereby allowing the coolant to change its flow direction in the cooling chamber 13 to improve the heat exchange rate of the coolant and ensure the cooling effect of the cooling plate 100.

[0047] In some embodiments, at least one turbulence fan blade 2 is provided in the inlet region 131.

[0048] Specifically, coolant can enter the inlet region 131 through the inlet 11, and at least one turbulence fan blade 2 is provided in the inlet region 131. That is, one, two or three turbulence fan blades 2 can be provided in the inlet region 131. When the driving member is connected to the turbulence fan blade 2, the driving member can drive the turbulence fan blade 2 to rotate in the opposite direction to the coolant in the inlet region 131, thereby turbulenting the coolant in the inlet region 131. When the driving member is disconnected from the turbulence fan blade 2, after the coolant enters the inlet region 131 from the inlet 11, it can push the turbulence fan blade 2 to rotate, thereby allowing the turbulence fan blade 2 to locally turbulent the coolant around it, thereby improving the heat transfer rate of the coolant in the inlet region 131 and improving the heat transfer effect of the cooling plate 100.

[0049] In other embodiments, at least one turbulence fan blade 2 is provided in the outflow region 132.

[0050] Specifically, the coolant in the inlet region 131 can flow in the first direction to the outlet region 132, and at least one turbulence fan blade 2 is provided in the outlet region 132. That is, one, two or three turbulence fan blades 2 can be provided in the outlet region 132. When the driving member is connected to the turbulence fan blade 2, the driving member can drive the turbulence fan blade 2 to rotate in the opposite direction to the coolant in the outlet region 132, thereby turbulenting the coolant in the outlet region 132. When the driving member is disconnected from the turbulence fan blade 2, after the coolant flows from the inlet region 131 to the outlet region 132, it can drive the turbulence fan blade 2 to rotate, thereby allowing the turbulence fan blade 2 to locally turbulent the coolant around it, thereby improving the heat transfer rate of the coolant in the outlet region 132, so as to improve the heat transfer effect of the cooling plate 100.

[0051] In some embodiments, a plurality of turbulence fan blades 2 are provided in the inlet region 131, and the plurality of turbulence fan blades 2 in the inlet region 131 are spaced apart in a second direction.

[0052] Specifically, multiple turbulence fan blades 2 are provided within the inlet region 131, meaning that two, three, or four turbulence fan blades 2 may be provided within the inlet region 131, such as... Figure 1 As shown, two turbulence fan blades 2 are provided in the inlet region 131. Coolant can enter the inlet region 131 through the inlet 11 along the second direction. The multiple turbulence fan blades 2 in the inlet region 131 are spaced apart in the second direction. That is, the coolant entering the inlet region 131 through the inlet 11 along the second direction can flow through the multiple turbulence fan blades 2, so that the multiple turbulence fan blades 2 can turbulent the coolant in the inlet region 131, thereby improving the heat exchange rate of the coolant in multiple places in the inlet region 131. When each turbulence fan in the inlet region 131 turbulents the coolant, some of the coolant can flow towards the outlet region 132, thereby making the coolant evenly distributed in the cooling chamber 13 and improving the cooling effect of the cooling plate 100.

[0053] In other embodiments, a plurality of turbulence fan blades 2 are provided in the outflow region 132, and the plurality of turbulence fan blades 2 in the outflow region 132 are spaced apart in the second direction.

[0054] Specifically, multiple turbulence fan blades 2 are provided within the outflow region 132, that is, two, three, or four turbulence fan blades 2 may be provided within the outflow region 132, such as... Figure 1As shown, two turbulence fan blades 2 are provided in the outflow region 132. Coolant can flow out of the outlet 12 through the outflow region 132 in the second direction. The multiple turbulence fan blades 2 in the outflow region 132 are spaced apart in the second direction. That is, the coolant flowing into the outflow region 132 can flow through multiple turbulence fan blades 2 and then flow towards the outlet 12. This allows multiple turbulence fan blades 2 to turbulent the coolant in the outflow region 132, thereby improving the heat exchange rate of the coolant in multiple places in the outflow region 132 and improving the cooling effect of the cooling plate 100.

[0055] In other embodiments, the inlet 11 and the outlet 12 are located on the same side of the main housing 1 and are spaced apart along a first direction.

[0056] Specifically, the main housing 1 is provided with an inlet 11 and an outlet 12 communicating with the cooling chamber 13, and as follows: Figure 1 As shown, the inlet 11 and outlet 12 are both located on the same side of the main housing 1. That is, the coolant enters the cooling chamber 13 from one side of the main housing 1, and after heat exchange in the cooling chamber 13, it still flows out of the cooling chamber 13 from the same side of the main housing 1. The inlet 11 and outlet 12 are spaced apart along the first direction, and the inlet region 131 and outlet region 132 are also distributed along the first direction. This allows the coolant to flow along the second direction after entering the inlet region 131 through the inlet 11, so as to flow through the multiple turbulence fan blades 2 in the inlet region 131. The turbulent coolant can then flow along the second direction to the outlet region 132. After being turbulent by the multiple turbulence fan blades 2, it flows along the first direction through the outlet 12 to the outside of the cooling chamber 13. This increases the flow path of the coolant in the cooling chamber 13, thereby improving the heat exchange efficiency of the coolant in the cooling chamber 13 and ensuring the reliability of the cooling plate 100.

[0057] In some embodiments, the cooling cavity 13 is provided with a plurality of cooling channels 14 distributed along a first direction, two adjacent cooling channels 14 are connected, and the plurality of cooling channels 14 are sequentially connected between the inlet 11 and the outlet 12, and each cooling channel 14 is provided with at least one turbulence fan blade 2.

[0058] Specifically, a cooling channel 14 is provided inside the cooling chamber 13, and as follows: Figure 2 As shown, multiple cooling channels 14 are provided, that is, two, three or four cooling channels 14 are provided. Multiple cooling channels 14 are distributed along the first direction. The number of cooling channels 14 can be set according to the size of the cooling cavity 13 in the first direction so that the cooling channels 14 fill the entire cooling cavity 13. The beginning and end of two adjacent cooling channels 14 can be connected, so that multiple cooling channels 14 can be distributed in series in the cooling cavity 13. The inlet 11 and the outlet 12 can be connected to the two ends of the cooling channel 14 respectively.

[0059] Therefore, the coolant entering the cooling chamber 13 through the inlet 11 can flow along the cooling channel 14, and the coolant after heat exchange in the cooling channel 14 can flow out of the cooling chamber 13 through the outlet 12, thereby ensuring the reliability of the coolant flow path, so as to ensure that the coolant flows through all parts of the cooling chamber 13 and ensure the reliability of the use of the cooling plate 100.

[0060] Furthermore, each cooling channel 14 is also provided with at least one turbulence fan blade 2, that is, each cooling channel 14 may be provided with one, two or three turbulence fan blades 2, so that the turbulence fan blades 2 flowing into each cooling channel 14 can turbulent the coolant in the corresponding cooling channel 14, thereby improving the heat dissipation rate of each cooling channel 14 and ensuring the cooling effect of the cooling plate 100.

[0061] In some embodiments, a plurality of turbulence fan blades 2 are provided, and the plurality of turbulence fan blades 2 are spaced apart and distributed in the cooling cavity 13.

[0062] Specifically, a turbulence fan blade 2 is provided inside the cooling cavity 13 to turbulent the coolant inside the cooling cavity 13, thereby improving the cooling effect of the cooling plate 100. Multiple turbulence fan blades 2 are provided, that is, two, three, or four turbulence fan blades 2 are provided. Multiple turbulence fan blades 2 are distributed at intervals inside the cooling cavity 13. That is, the number of turbulence fan blades 2 can be set according to the size of the cooling cavity 13. When the cooling cavity 13 is large, the number of turbulence fan blades 2 can be increased. When the cooling cavity 13 is small, the number of turbulence fan blades 2 can be reduced. In this way, the installation cost can be reduced while ensuring the turbulence effect.

[0063] Furthermore, when the coolant enters the inlet region 131 of the cooling chamber 13 through the inlet 11 in the second direction, it can flow to the outlet region 132 in the first direction, and then flow out of the cooling chamber 13 through the outlet 12 in the second direction. That is, the coolant can be distributed in various parts of the cooling chamber 13. By setting multiple spaced-apart turbulence fan blades 2 in the cooling chamber 13, the coolant in various parts of the cooling chamber 13 can be turbulent, so as to ensure the turbulence effect and improve the reliability of the turbulence fan blades 2.

[0064] In some embodiments, multiple driving elements are provided, and the multiple driving elements and multiple turbulence fan blades 2 are distributed in a one-to-one correspondence.

[0065] Specifically, multiple turbulence fan blades 2 are provided in the cooling chamber 13 to ensure the turbulence effect on the coolant in various parts of the cooling chamber 13. The turbulence fan blades 2 are selectively connected to a driving component. Multiple driving components can be provided, such as two, three, or four. The multiple driving components and multiple turbulence fan blades 2 are distributed in a one-to-one correspondence, so that each turbulence fan blade 2 is selectively connected to a driving component. The driving component can be a drive motor, etc., and the motor shaft of the drive motor can be connected to the turbulence fan blade 2, so that when the drive motor is running, the drive shaft can drive the turbulence fan blade 2 to rotate.

[0066] Therefore, by selectively connecting each turbulence fan blade 2 to a drive component, the reliability of the operation of each turbulence fan blade 2 can be guaranteed, and the failure of a single drive component can be avoided from affecting the other drive components, thus ensuring the reliability of the operation of the turbulence fan blade 2 and, in turn, the reliability of the use of the cooling plate 100.

[0067] In other embodiments, a single drive unit is provided, and the drive unit is used to be poweredly connected to a plurality of turbulence fan blades 2 respectively.

[0068] Specifically, multiple turbulence fan blades 2 are provided in the cooling chamber 13 to ensure the turbulence effect on the coolant in various parts of the cooling chamber 13. The turbulence fan blades 2 are selectively connected to a drive unit. The drive unit can be set to one, and one drive unit can be selectively connected to multiple turbulence fan blades 2. In actual installation, the drive unit can be set to a drive motor, and the rotating shaft of each turbulence fan blade 2 can be equipped with a rotating gear. The motor shaft of the drive motor can also be equipped with a drive gear. A gear set or worm gear structure can be set between the drive gear and the rotating gear, so that one drive unit can synchronously drive multiple turbulence fan blades 2 to rotate.

[0069] Therefore, by driving multiple turbulence fan blades 2 to rotate through one drive unit, the installation cost can be reduced, and the synchronicity of the operation of each turbulence fan blade 2 can be guaranteed to ensure the consistency of the turbulence effect on the coolant in various parts of the cooling chamber 13, thereby ensuring the cooling effect of the cooling plate 100.

[0070] In some embodiments, the cooling cavity 13 is further provided with a turbulence protrusion 3, and the turbulence protrusion 3 and the turbulence fan blade 2 are distributed at intervals.

[0071] Specifically, the cooling cavity 13 may also be provided with turbulence protrusions 3, which may be circular protrusions or block-shaped protrusions, etc. In this embodiment, for example... Figure 2As shown, the turbulence protrusion 3 can be configured as a block protrusion, and there can be multiple turbulence protrusions 3. Multiple turbulence protrusions 3 are distributed in the cooling cavity 13 at intervals. The extension direction of the turbulence protrusion 3 is set to be different from the flow direction of the coolant, so that the flow direction of the coolant flowing to the turbulence protrusion 3 can be changed, thereby locally turbulentizing the coolant to ensure the heat dissipation rate of the coolant. The turbulence protrusion 3 and the turbulence fan blade 2 are distributed at intervals, so that the coolant can flow through the turbulence fan blade 2 and the turbulence protrusion 3 in sequence, thereby turbulentizing the coolant in multiple directions to ensure the reliability of the turbulence.

[0072] In other embodiments, the main housing 1 is further provided with heat dissipation parts, which are spaced apart on the outer wall of the main housing 1 and protrude outward relative to the outer wall of the main housing 1.

[0073] Specifically, the main housing 1 is provided with a heat dissipation part, which can be configured as a heat dissipation strip or heat dissipation protrusion, etc., and multiple heat dissipation parts can be configured. Multiple heat dissipation parts are distributed at intervals on the outer wall of the main housing 1 and protrude outward relative to the outer wall of the main housing 1. The main housing 1 can be configured as a rectangle, etc., and the heat dissipation parts can be provided on multiple outer wall surfaces of the main housing 1. Each outer wall surface of the main housing 1 can be provided with a heat dissipation part. The heat dissipation parts protrude outward relative to the outer wall of the main housing 1, thereby increasing the area of ​​the main housing 1 and increasing the contact area between the main housing 1 and the outside world. As a result, the heat dissipation speed of the main housing 1 can be increased, thereby improving the performance of the cooling plate 100.

[0074] This utility model also proposes a battery pack.

[0075] The battery pack according to the present invention includes the cooling plate 100 of any of the above.

[0076] According to the battery pack of this utility model embodiment, a cooling plate 100 is provided, and the cooling plate 100 can turbulently flow the coolant in the cooling cavity 13 by providing at least one turbulence fan blade 2 in the cooling cavity 13. The structure is simple, allowing the coolant to absorb more heat and improve the heat dissipation efficiency of the coolant, thereby improving the cooling effect of the cooling plate 100 and ensuring the reliability of the cooling plate 100. In addition, a drive component is provided that is selectively powered to the turbulence fan blade 2, so that the turbulence fan blade 2 can be actively rotated by the drive component or rotated with the medium. The usage mode is flexible, which can meet different usage needs, and the usage effect is better and the application range is wider.

[0077] This utility model also proposes a vehicle.
