Description

Technical Field

[0001] This invention relates to the field of liquid cooling plate technology for battery packs, and in particular to a liquid cooling plate for battery packs. Background Technology

[0002] Battery packs are used to store energy to power devices when needed. However, battery packs also generate heat during use. If this heat is not dissipated in time, the battery pack temperature will become too high, directly leading to damage. In particular, the operating current of battery packs in new energy vehicles is high, generating a large amount of heat. Furthermore, because the battery pack is in a relatively enclosed environment, its temperature rises further, increasing the probability of damage. Therefore, liquid cooling plates are typically used to dissipate heat from new energy vehicle battery packs.

[0003] However, liquid cooling plates cannot be adjusted in length to suit the actual space requirements when dealing with battery packs of different sizes and module arrangements. They can only be custom-made for specific battery pack models. This not only increases the mold costs and time cycle for developing battery packs for new models, but also leads to increased inventory pressure, as liquid cooling plates of different lengths need to be stocked separately. Furthermore, if the original model of liquid cooling plate is out of stock during later battery pack repairs or replacements, it cannot be adapted by adjusting the length, which will prolong the repair cycle and affect the efficiency of use. Therefore, there is an urgent need for a liquid cooling plate that can adapt to battery packs of different sizes and module arrangements. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of this invention is to provide a liquid cooling plate for battery packs that can flexibly adapt to battery packs of different sizes and module arrangements, eliminating the need for separate customization for specific battery pack models.

Therefore, they should not be construed as limitations on this invention.

[0021] Furthermore, features specified as "first" or "second" may explicitly or implicitly include one or more of the same feature, used to distinguish and describe features, without any order or distinction of importance.

[0022] In the description of this invention, unless otherwise stated, "a plurality of" means two or more. In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] The following is for reference. Figures 1-4 The present invention describes a liquid cooling plate 100 for a battery pack according to an embodiment of the present invention.

[0024] like Figures 1 to 3 As shown, the liquid cooling plate 100 for a battery pack according to an embodiment of the present invention includes: a liquid cooling plate body 10, two clamping members 20, and a driving member 30. The two clamping members 20 are spaced apart on the liquid cooling plate body 10 in a first direction to jointly form a clamping space 20a for clamping the battery pack, and the two clamping members 20 are movable along the first direction. The driving member 30 is disposed on the liquid cooling plate body 10 and drives the two clamping members 20, for driving the two clamping members 20 closer together or further apart to adjust the clamping space 20a.

[0025] The liquid cooling plate body 10 can refer to a component that reduces the temperature of the battery pack, and its shape can be, but is not limited to, rectangular, circular, and irregular shapes, etc.

[0026] The clamping component 20 can refer to a component that restricts the displacement of the battery pack, and can be made of, but is not limited to, metal, plastic, and composite materials. Two clamping components 20 are spaced apart on the liquid cooling plate body 10 in the first direction to jointly form a clamping space 20a for clamping the battery pack. The two clamping components 20 can move along the first direction, thereby adjusting the size of the clamping space 20a in the first direction to accommodate battery packs of different sizes. The term "first direction" can be referenced from... Figure 2 The left and right directions.

[0027] The driving component 30 can refer to the component that drives the clamping component 20 to move, and can be, but is not limited to, a screw, set screw, bolt, hydraulic cylinder, pneumatic cylinder, electric push rod, and wedge block adjustment mechanism, etc.

[0028] The number of battery packs installed in the clamping space 20a can be one or more.

[0029] In the above technical solution, before assembling the battery pack and the liquid cooling plate 100 for the battery pack, the driving component 30 is used to move the two clamping components 20 away from each other, ensuring that the length of the clamping space 20a is greater than the length of the battery pack in at least the first direction. Then, the battery pack is placed into the clamping space 20a, and the driving component 30 drives the two clamping components 20 closer together to reduce the clamping space 20a. This ensures that the battery pack can be stably clamped on the liquid cooling plate body 10, preventing relative displacement between the battery pack and the liquid cooling plate body 10 due to bumps or vibrations during vehicle operation, which would affect the heat dissipation effect.

[0030] According to an embodiment of the present invention, the liquid cooling plate 100 for battery packs can flexibly adjust the size of the clamping space 20a in the first direction by driving the two clamping components 20 to move closer or further apart through the driving component 30. This increases or decreases the size of the clamping space 20a, thereby changing the overall adaptability length of the liquid cooling plate. This allows for flexible adaptation to battery packs of different sizes and module arrangements, eliminating the need for custom-made molds for specific battery pack models. This significantly reduces the mold costs and development cycle for new vehicle models, simplifies inventory management, and reduces the inventory pressure of liquid cooling plates of different specifications. Furthermore, during later maintenance or replacement of the battery pack, the length can be quickly adjusted to meet adaptation requirements, shortening the maintenance cycle and improving the efficiency and versatility of the liquid cooling plate 100 for battery packs.

[0031] In some embodiments of the present invention, reference is made to Figure 2 The clamping component 20 includes a first clamping member 21 and a second clamping member 22. The first clamping member 21 is slidably disposed on the liquid cooling plate body 10 and extends along a second direction, which is perpendicular to the first direction. The second clamping member 22 is disposed on the first clamping member 21 and protrudes relative to the first clamping member 21 in the first direction.

[0032] The "second direction" can be referenced. Figure 2 The front and back directions.

[0033] In the above technical solution, the first clamping member 21 is slidably disposed on the liquid cooling plate body 10 and extends along the second direction, which can increase the contact area between the first clamping member 21 and the battery pack, improve the connection stability between the clamping member 20 and the battery pack, prevent the battery pack from shaking in the first direction, and improve the reliability of the liquid cooling plate 100 for the battery pack. The second clamping member 22 is disposed on the first clamping member 21 and protrudes relative to the first clamping member 21 in the first direction, which can restrict the displacement of the battery pack in the height direction of the battery pack, further improving the reliability of the liquid cooling plate 100 for the battery pack.

[0034] In some embodiments of the present invention, reference is made to Figure 2The first clamping member 21 includes a first clamping plate 211 and a sliding block 212. The first clamping plate 211 extends along the second direction and is connected to the second clamping member 22. The sliding block 212 is disposed on the first clamping plate 211. The liquid cooling plate body 10 is provided with a strip hole 10a. The strip hole 10a extends along the first direction and slides in cooperation with the sliding block 212.

[0035] The shape of the first clamping plate 211 can be, but is not limited to, rectangular, U-shaped, convex, etc., for example, see reference. Figure 2 The first clamp 211 is U-shaped, which can save materials and reduce costs.

[0036] In the above technical solution, the strip hole 10a extends along the first direction and slides in cooperation with the sliding block 212. The strip hole 10a can provide guidance for the movement of the sliding block 212 in the first direction, avoiding deviation or jamming during the adjustment process, and ensuring that the first clamping member 21 can move smoothly and accurately along the first direction. At the same time, the structural design of the strip hole 10a and the sliding block 212 is simple and easy to process and assemble.

[0037] In some embodiments of the present invention, reference is made to Figure 2 The sliding block 212 is provided with a guide hole 212a, and a guide rod 12 is provided in the strip hole 10a. The guide rod 12 extends along the first direction and slides in cooperation with the guide hole 212a.

[0038] The guide hole 212a and the guide rod 12 have matching shapes, which can be, but are not limited to, circles, polygons, and irregular shapes. For example, if the guide hole 212a and the guide rod 12 have circular cross-sections, it can reduce the difficulty of machining and reduce the frictional resistance during sliding.

[0039] In the above technical solution, the guide rod 12 extends along the first direction and slides in cooperation with the guide hole 212a of the sliding block 212. This further improves the guiding accuracy and stability of the sliding block 212 as it moves within the strip hole 10a, ensuring more precise movement trajectories of the two clamping components 20 when they approach or move away from each other, thereby guaranteeing the accuracy of the clamping space 20a adjustment. Simultaneously, the guide rod 12 also provides some support for the sliding block 212, dispersing the contact stress between the sliding block 212 and the strip hole 10a, reducing wear, and extending the service life of the components.

[0040] In some embodiments of the present invention, reference is made to Figure 3The liquid cooling plate body 10 is provided with a mounting plate 11, and the mounting plate 11 is provided with a mounting hole 11a. The driving component 30 includes a first threaded rod 31, a turntable 32, a bearing 33, and a handle 34. The first threaded rod 31 is rotatably mounted in the mounting hole 11a. The first threaded rod 31 is a double-ended screw and is screwed to two sliding blocks 212. The turntable 32 is connected to the first threaded rod 31. The handle 34 is mounted on the turntable 32 through the bearing 33. The handle 34 is eccentrically set relative to the turntable 32.

[0041] The turntable 32, bearing 33, and handle 34 are located at one end of the first threaded rod 31, or the turntable 32, bearing 33, and handle 34 are located at both ends of the first threaded rod 31. For example, refer to... Figure 3 The turntable 32, bearing 33 and handle 34 are located at one end of the first threaded rod 31.

[0042] Understandably, the outer surface of the handle 34 is provided with anti-slip pads to increase the roughness of the handle 34, prevent the operator from slipping when turning the handle 34, and improve the safety and convenience of operation.

[0043] In the above technical solution, when the first threaded rod 31 rotates, the screw connection between the first threaded rod 31 and the two sliding blocks 212 converts the rotational motion into linear motion of the two sliding blocks 212 along the first direction. The two sliding blocks 212 move in opposite directions, i.e., one sliding block 212 moves closer to the other, thereby causing the first clamping plate 211 connected to the sliding blocks 212 to move synchronously. This allows the two clamping components 20 to either move closer to each other to reduce the clamping space 20a, or move further apart to increase the clamping space 20a, making operation simple and convenient. Simultaneously, the handle 34 is eccentrically positioned relative to the turntable 32, effectively reducing the torque required during operation. This allows the operator to easily drive the first threaded rod 31 to rotate by turning the handle 34, improving the convenience and ease of adjustment.

[0044] In addition, the first threaded rod 31 is a double-ended threaded rod and is threaded to the two sliding blocks 212. It also slides with the guide hole 212a through the guide rod 12, which plays a precise guiding role in the sliding trajectory of the sliding block 212. This prevents the sliding block 212 from deviating, shaking or getting stuck due to the rotation of the first threaded rod 31, and ensures that the sliding block 212 drives the first clamping plate 211 to move smoothly and steadily. This ensures the accuracy and reliability of the length adjustment process of the clamping space 20a and improves the operational stability of the overall structure.

[0045] In some embodiments of the present invention, reference is made to Figure 2 The second clamping member 22 includes a connecting plate 221 and a second clamping plate 222. The connecting plate 221 extends along a second direction and connects to the first clamping plate 211. The second clamping plate 222 connects to the connecting plate 221 and extends along a first direction.

[0046] The second clamp 222 has a protective pad on the side closest to the battery pack.

[0047] In the above technical solution, the second clamping plate 222 is connected to the connecting plate 221 and extends along the first direction, so that the second clamping plate 222 can effectively block the battery pack in the height direction, limiting the displacement of the battery pack in the height direction. At the same time, this structural design allows the second clamping member 22 and the first clamping member 21 to work together to limit the battery pack from different directions, enhance the stability of the battery pack clamping, effectively prevent the battery pack from loosening or falling off under complex working conditions such as vehicle driving, and further improve the reliability of the liquid cooling plate 100 for the battery pack.

[0048] In some embodiments of the present invention, reference is made to Figure 2 The clamping component 20 includes an adjusting component 23. The second clamping member 22 is connected to the first clamping member 21 through the adjusting component 23. The adjusting component 23 is configured to adjust the second clamping member 22 to move upward relative to the first clamping member 21 in a third direction. The third direction, the second direction, and the first direction are perpendicular to each other.

[0049] Among them, "third-party" can be referenced. Figure 2 The up and down directions.

[0050] The adjusting component 23 can be, but is not limited to, a threaded and screw mechanism, a hydraulic cylinder, a pneumatic cylinder, an electric push rod, and a wedge block adjusting mechanism, etc.

[0051] In the above technical solution, by adjusting the position of the second clamping member 22 in the third-party direction using the adjusting component 23, it is possible to further adapt to battery packs of different heights and sizes. When the battery pack is high, the second clamping member 22 can be moved upward by adjusting the component 23 to avoid interference with the top of the battery pack; when the battery pack is low, the second clamping member 22 is moved downward to ensure that the second clamping plate 222 can reliably abut against the top surface of the battery pack, thereby effectively limiting the battery pack in the third-party direction and preventing the battery pack from jumping or shifting in the third-party direction. This further improves the comprehensiveness and stability of clamping, allowing the liquid cooling plate 100 for the battery pack to flexibly adapt to battery packs of different sizes and module arrangements without the need for separate customization for specific battery pack models. This significantly reduces the mold cost and cycle of new vehicle development, makes inventory management more convenient, and reduces the inventory pressure of liquid cooling plates of different specifications. In addition, during later maintenance or replacement of the battery pack, the length can be quickly adjusted to meet the requirements, shortening the maintenance cycle and improving the efficiency and adaptability of the liquid cooling plate 100 for the battery pack.

[0052] In some embodiments of the present invention, reference is made to Figure 2The adjusting component 23 includes a threaded cylinder 231, a second threaded rod 232, and a throttle 233. The threaded cylinder 231 is mounted on the first clamping member 21. The second threaded member is rotatably mounted on the second clamping member 22 and screwed to the threaded cylinder 231. The second threaded rod 232 and the threaded cylinder 231 extend in a third direction. The throttle 233 is mounted on the second threaded rod 232.

[0053] Understandably, reference Figure 2 The second threaded rod 232 is rotatably connected to the connecting plate 221. Rotating the handle 233 on the outer surface of the second threaded rod 232 causes the threaded rod 232 to rotate within the threaded cylinder 231 at the upper end of the first clamping plate 211. Because the second threaded rod 232 is rotatably connected to the connecting plate 221, the thread action drives the connecting plate 221 to move up and down, thereby causing the second clamping plates 222 on both sides of the connecting plate 221 to rise and fall synchronously until the protective pad on the lower surface of the second clamping plate 222 adheres to the upper surface of the battery pack, completing the fixation. Therefore, the height of the second clamping plate 222 can be flexibly adjusted via the second threaded rod 232 to accommodate battery packs of different thicknesses, improving the adaptability of the fixation. The second clamping plate 222, together with the protective pad, can firmly press the battery pack down from above, preventing the battery pack from shifting under vibration, bumps, or other operating conditions, ensuring safety during use.

[0054] In the above technical solution, the second threaded rod 232 is screwed to the threaded cylinder 231. When the handle 233 is rotated, the second threaded rod 232 moves linearly in a third direction within the threaded cylinder 231, thereby driving the connected second clamping member 22 to move synchronously, realizing the height adjustment of the second clamping plate 222 to adapt to battery packs of different thicknesses and improve the compatibility of the fixation. At the same time, this structure and adjustment method are simple and easy for operators to assemble or repair and replace.

[0055] In some embodiments of the present invention, reference is made to Figure 2 The first clamping member 21 is provided with two guide sleeves 213, which are spaced apart in the second direction. The second clamping member 22 is provided with two guide posts 223, which are arranged in a one-to-one correspondence with the two guide sleeves 213. The guide posts 223 and the guide sleeves 213 are guided and cooperated in the third direction.

[0056] The shape of the guide post 223 and the guide sleeve 213 can be, but is not limited to, a cylinder, a cuboid, and other pillars, etc.

[0057] In the above technical solution, the guide post 223 and the guide sleeve 213 are slidably inserted and connected in a third direction to provide guidance for the movement of the second clamping member 22 in the third direction, to prevent the second clamping member 22 from rotating or deviating from the predetermined trajectory, to ensure the accuracy and reliability of the adjustment process of the second clamping member 22, and to improve the operational stability of the overall structure.

[0058] In some embodiments of the present invention, reference is made to Figure 3 and Figure 4 The liquid cooling plate body 10 has a cooling surface 10b, and two clamping components 20 are provided on one side of the cooling surface 10b of the liquid cooling plate body 10. The liquid cooling plate body 10 is provided with a cooling channel 10c, which is located on the other side of the liquid cooling plate body 10 away from the cooling surface 10b. The liquid cooling plate 100 for the battery pack includes a protective shell 40, which covers the liquid cooling plate body 10. The cooling channel 10c and the driving component 30 are located inside the protective shell 40.

[0059] The shape of the cooling channel 10c can be, but is not limited to, serpentine, U-shaped, grid-shaped, etc. Coolant flows inside the cooling channel 10c to reduce the temperature of the battery pack.

[0060] The liquid cooling plate body 10 has an inlet head 13 and an outlet head 14 at its end, both of which are connected to the cooling channel 10c to ensure coolant circulation. Additionally, the protective shell 40 has an opening 40a and a clearance groove 40b. The inlet head 13 and the outlet head 14 pass through the clearance groove 40b, and the drive component 30 is partially located at the opening 40a. This allows the drive component 30 to be adjusted and the clamping component 20 to adapt to battery packs of different sizes and module arrangements without disassembling the protective shell 40.

[0061] In the above technical solution, the protective shell 40 covers the liquid cooling plate body 10, providing physical protection for the internal components and preventing damage from accidental collisions or impacts during assembly, transportation, or vehicle operation, thus ensuring the integrity of the overall structure of the battery pack liquid cooling plate 100. Simultaneously, the protective shell 40 also encloses core components such as the cooling channel 10c and the drive component 30, effectively isolating them from external dust, moisture, oil, and other contaminants that could corrode the internal structure. This prevents impurities from entering and causing rust or jamming of the drive component 30, affecting its adjustment function, thereby improving the service life and operational reliability of the battery pack liquid cooling plate 100.

[0062] The following is combined Figures 1 to 4 This describes a specific embodiment of the liquid cooling plate 100 for battery packs of the present invention.

[0063] The liquid cooling plate 100 for the battery pack includes: a liquid cooling plate body 10, two clamping components 20, a driving component 30, and a protective shell 40.

[0064] The liquid cooling plate body 10 is provided with a mounting plate 11 and a strip hole 10a. The mounting plate 11 is provided with mounting holes 11a and the strip hole 10a extends in the left and right direction and slides in cooperation with the sliding block 212. The liquid cooling plate body 10 has a cooling surface 10b, and two clamping components 20 are provided on one side of the liquid cooling plate body 10 where the cooling surface 10b is located. The liquid cooling plate body 10 is provided with a cooling channel 10c, which is located on the other side of the liquid cooling plate body 10 away from the cooling surface 10b.

[0065] Two clamping components 20 are spaced apart on the liquid cooling plate body 10 in the left-right direction to jointly form a clamping space 20a for clamping the battery pack, and the two clamping components 20 are movable in the left-right direction. Each clamping component 20 includes a first clamping member 21, a second clamping member 22, and an adjusting member 23. The first clamping member 21 is slidably disposed on the liquid cooling plate body 10 and extends in the front-back direction. The second clamping member 22 is disposed on the first clamping member 21 and protrudes from the first clamping member 21 in the left-right direction. The second clamping member 22 is connected to the first clamping member 21 via the adjusting member 23, which is configured to adjust the second clamping member 22's vertical movement relative to the first clamping member 21. The first clamping member 21 includes a first clamping plate 211 and a sliding block 212.
