[0010] In some alternative embodiments, the liquid cooling assembly further includes a magnetic chuck assembly disposed between the upper plate of the liquid cooling plate and the lower plate of the liquid cooling plate, so that the lower plate of the liquid cooling plate is detachable from the upper plate of the liquid cooling plate.

[0011] It should be noted that the magnetic assembly provides a quick and simple connection method, making the assembly and disassembly of the liquid cooling plate and base plate much more convenient, and can be performed without tools.

[0020] It should be noted that the first connector provides additional mechanical fixation to ensure a more secure connection between the first magnetic connector and the liquid cooling plate, and the second connector provides additional mechanical fixation to ensure a more secure connection between the second magnetic connector and the liquid cooling plate base plate, reducing loosening or displacement caused by vibration or impact.

[0021] In some alternative implementations, the structures of the first connector and the first magnetic attractor are matched.

[0022] The second connector and the second magnetic connector are structurally compatible.

[0023] It should be noted that through structural matching, the connection between the connector and the magnetic clasp is tighter, reducing the risk of loosening at the connection and improving the overall structural stability. The structural matching design ensures that the connector and the magnetic clasp can be accurately aligned and engaged, reducing errors during assembly and improving the overall assembly accuracy of the components.

[0024] In some alternative embodiments, at least one of the first connector and the second connector is a sheet adhesive.

[0025] It should be noted that sheet adhesive is easy to apply, requiring only simple bonding steps to complete installation without complicated tools or equipment, thus simplifying the assembly process and improving production efficiency. Sheet adhesive provides uniform adhesion, ensuring a more even stress distribution between connectors and magnetic components, reducing localized stress concentrations, and extending the lifespan of the components.

[0026] In some alternative implementations, the liquid cooling assembly further includes at least two limiting elements;

[0027] At least two limiting members are located at the edges of the upper part of the liquid cooling plate, and the at least two limiting members form a limiting space so that the bottom plate of the liquid cooling plate is located within the limiting space.

[0028] It should be noted that the limiting component provides additional mechanical constraints to ensure that the liquid cooling plate base plate remains in a stable position within the limiting space, preventing displacement or misalignment caused by external vibration or impact.

[0029] In some alternative implementations, the limiting member includes a first limiting edge and a second limiting edge connected together;

[0030] The first limiting edge abuts against the first side edge of the liquid cooling plate base plate, and the second limiting edge abuts against the second side edge of the liquid cooling plate base plate;

[0031] The first side and the second side of the liquid-cooled plate base plate are two adjacent edges.

[0032] It should be noted that, through the interaction of the first and second limiting edges, the liquid cooling plate base plate can be precisely positioned within the limiting space, ensuring that it always maintains the correct position and alignment during operation.

[0033] In addition, this application also provides a CTP battery pack, including a housing, thermally conductive adhesive, battery cells, and the aforementioned liquid cooling components;

[0034] The enclosure has a receiving cavity for housing the battery cells and liquid cooling components;

[0035] The battery cell is attached to the liquid cooling assembly via thermally conductive adhesive, and the liquid cooling assembly is used to exchange heat with the battery cell.

[0036] The liquid cooling assembly and CTP battery pack provided in this application include a housing, thermally conductive adhesive, battery cells, and the aforementioned liquid cooling assembly. The housing has a receiving cavity for accommodating the battery cells and the liquid cooling assembly. The battery cells are mounted on the liquid cooling assembly via thermally conductive adhesive, and the liquid cooling assembly is used for heat exchange between the battery cells.

[0057] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. All other obtained embodiments are within the scope of protection of this application. In the absence of conflict, the following embodiments and features can be combined with each other.

[0058] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0061] In the process of conceiving and implementing this application, the applicant discovered at least the following problems: In the current CTP cell bottom cooling solution, the cell is bonded to the liquid cooling plate by thermally conductive structural adhesive, and the liquid cooling plate is connected to the flow channel plate by brazing. When the bottom impact position of the battery pack is located on the flow channel, it is easy to cause permanent deformation of the flow channel due to compaction.

[0062] The liquid cooling assembly proposed in this application features a detachable design for the liquid cooling plate base and the liquid cooling plate upper plate. This allows for quick removal and repair or replacement if either component is damaged, reducing costs and enabling timely replacement of damaged parts, thus extending the overall service life of the liquid cooling assembly.

[0063] The liquid cooling assembly provided in this application will be described in detail below with reference to specific embodiments.

[0064] Figure 1 This is an exploded view of the liquid cooling assembly according to an embodiment of this application.

[0065] like Figure 1 As shown in the figure, this application embodiment proposes a liquid cooling assembly 100, including:

[0066] Liquid cooling plate, upper plate 110;

[0067] The liquid cooling plate base plate 120 is detachably connected to the liquid cooling plate upper plate 110, wherein the liquid cooling plate base plate 120 has a liquid cooling channel for the flow of coolant.

[0068] It should be noted that, through the design of the liquid cooling channel, the coolant can flow efficiently within the liquid cooling plate base 120, quickly carrying away heat and thus improving heat dissipation efficiency.

[0069] If the liquid cooling channels are compacted or permanently deformed during an impact, causing liquid cooling failure, the detachable design allows for quick removal of the damaged liquid cooling plate base 120 for repair or replacement, reducing maintenance costs. Compared to replacing the entire liquid cooling assembly 100, replacing only the damaged liquid cooling plate base 120 significantly reduces maintenance and material costs, and allows for timely replacement of damaged components, extending the service life of the entire liquid cooling assembly 100.

[0070] After an impact, the liquid cooling system can quickly restore normal function, ensuring temperature control of the battery pack and other critical components, thereby improving the reliability and safety of the entire system.

[0071] Furthermore, by optimizing the flow channel design and material selection, the liquid cooling component 100 can maintain stable performance during long-term operation, reducing battery pack failures caused by overheating.

[0072] By making the liquid cooling plate base plate 120 and the liquid cooling plate upper plate 110 detachable, the liquid cooling plate base plate 120 and the liquid cooling plate upper plate 110 can be quickly removed for repair and replacement when either of them is damaged, thereby reducing costs and allowing for timely replacement of damaged parts, thus extending the service life of the entire liquid cooling assembly 100.

[0073] In some alternative embodiments, the liquid cooling assembly 100 further includes a magnetic attraction assembly 130, which is disposed between the upper liquid cooling plate 110 and the lower liquid cooling plate 120, so that the lower liquid cooling plate 120 is detachable from the upper liquid cooling plate 110.

[0074] It should be noted that the magnetic assembly 130 provides a quick and simple connection method, making the assembly and disassembly of the liquid cooling plate 110 and the base plate much more convenient, and can be performed without the use of tools. This greatly simplifies the maintenance and replacement process.

[0075] The magnetic assembly 130 can provide uniform adsorption force to ensure tight contact between the upper plate 110 and the lower plate 120 of the liquid cooling plate, thereby improving the sealing performance and preventing coolant leakage.

[0076] In addition, the magnetic connection has a certain degree of flexibility, which can absorb and buffer external impacts or vibrations to a certain extent, reduce direct damage to the flow channel, and enhance the system's impact resistance.

[0077] Furthermore, the magnetic assembly 130 allows for quick replacement of different types of liquid cooling plate upper plates 110 and liquid cooling plate base plates 120 to adapt to different cooling needs or structural requirements. Since the magnetic assembly 130 typically has a long service life and does not require frequent replacement, maintenance and replacement costs can be reduced over long-term use.

[0078] In some alternative embodiments, the magnetic attraction assembly 130 includes a first magnetic attraction element 131 and a second magnetic attraction element 132;

[0079] The first magnetic absorbing element 131 is disposed on the upper plate 110 of the liquid cooling plate, and the second magnetic absorbing element 132 is disposed on the bottom plate 120 of the liquid cooling plate. The first magnetic absorbing element 131 and the second magnetic absorbing element 132 attract each other so that the upper plate 110 of the liquid cooling plate and the bottom plate 120 of the liquid cooling plate are connected.

[0080] It should be noted that the magnetic force between the first magnetic accumulator 131 and the second magnetic accumulator 132 provides a stable connection, enabling the upper plate 110 of the liquid cooling plate and the lower plate 120 of the liquid cooling plate to be firmly connected, ensuring that they are not easily loosened or separated under normal operating conditions.

[0081] The uniform attraction force of the first magnetic element 131 and the second magnetic element 132 helps to maintain a tight contact between the upper plate 110 of the liquid cooling plate and the lower plate 120 of the liquid cooling plate, thereby improving the sealing performance and preventing coolant leakage.

[0082] In addition, the magnetic connection allows users to quickly assemble and disassemble the upper plate 110 and the lower plate 120 of the liquid cooling plate without tools. This convenience greatly simplifies the maintenance and replacement process and improves work efficiency.

[0083] By replacing different types or strengths of magnetic components, the strength and characteristics of the connection can be adjusted to suit different application requirements and environmental conditions.

[0084] It should be noted that in the event of an accidental impact, the magnetic connection can separate the upper plate 110 and the lower plate 120 of the liquid cooling plate to a certain extent, avoiding excessive stress concentration in one place, thereby protecting the integrity of the liquid cooling assembly 100.

[0085] In some alternative embodiments, at least one of the first magnetic member 131 and the second magnetic member 132 is a magnetic sheet.

[0086] It should be noted that the use of magnetic clasps can effectively reduce material and manufacturing costs, thereby making the overall cost of the liquid cooling component 100 more competitive.

[0087] It should be noted that magnetic clasps are typically thin and lightweight, which helps reduce the overall weight of the liquid cooling assembly 100. Furthermore, magnetic clasps can be cut into various shapes and sizes, providing greater design flexibility. This allows for better adaptation to the geometry and structural requirements of the liquid cooling plate, optimizing space utilization.

[0088] Magnetic clasps provide a uniform magnetic force distribution, ensuring a stable connection between the upper liquid cooling plate 110 and the lower liquid cooling plate 120. This helps improve the reliability of the connection and sealing performance. Since magnetic clasps are typically self-adhesive or easy to fix, they can be quickly installed on the upper liquid cooling plate 110 and the lower liquid cooling plate 120, simplifying the production and assembly process.

[0089] In some embodiments, high-quality magnetic clasps typically have good corrosion and wear resistance, and can maintain stable performance under various environmental conditions, thereby improving the durability and reliability of the liquid cooling assembly 100.

[0090] In addition, the flexibility of the magnetic stabilizing plate can provide a certain buffering effect in the event of an accidental impact, reducing damage to the liquid cooling component 100.

[0091] In some alternative embodiments, the liquid cooling assembly 100 further includes a first connector 140 and a second connector 150;

[0092] The first connector 140 is located between the upper plate of the liquid cooling plate 110 and the first magnetic member 131, so that the upper plate of the liquid cooling plate 110 and the first magnetic member 131 are connected.

[0093] The second connector 150 is located between the liquid cooling plate base plate 120 and the second magnetic connector 132, so that the liquid cooling plate base plate 120 and the second magnetic connector 132 are connected.

[0094] It should be noted that the first connector 140 provides additional mechanical fixation to ensure a more stable connection between the first magnetic 131 and the upper plate 110 of the liquid cooling plate, and the second connector 150 provides additional mechanical fixation to ensure a more stable connection between the second magnetic 132 and the bottom plate 120 of the liquid cooling plate, reducing loosening or displacement caused by vibration or impact.

[0095] In some embodiments, the first connector 140 may be made of a material compatible with the upper plate 110 of the liquid cooling plate and the first magnetic 131, and the second connector 150 may be made of a material compatible with the bottom plate 120 of the liquid cooling plate and the second magnetic 132, to ensure good bonding between different materials and avoid connection failure due to material incompatibility.

[0096] In other embodiments, the connector may be designed to have a certain degree of elasticity or cushioning characteristics to further absorb and mitigate the impact of external shocks or vibrations on the liquid cooling system.

[0097] In some alternative embodiments, the first connector 140 and the first magnetic member 131 are structurally matched;

[0098] The second connector 150 and the second magnetic connector 132 are structurally matched.

[0099] It should be noted that through structural matching, the connection between the connector and the magnetic clasp is tighter, reducing the risk of loosening at the connection and improving the overall structural stability. The structural matching design ensures that the connector and the magnetic clasp can be accurately aligned and engaged, reducing errors during assembly and improving the overall assembly accuracy of the components.

[0100] In addition, structural matching helps ensure a tight fit between the connector and the magnetic chuck, thereby improving sealing performance and preventing coolant leakage.

[0101] In some embodiments, the first connector 140 has a first connecting surface and a second connecting surface, wherein the first connecting surface is in close contact with the back surface of the upper plate 110 of the liquid cooling plate, and the second connecting surface is in close contact with the side surface of the first magnetic member 131.

[0102] In some embodiments, the second connector 150 has a third connecting surface and a fourth connecting surface, wherein the third connecting surface is in close contact with the top surface of the liquid cooling plate base plate 120, and the fourth connecting surface is in close contact with the side surface of the second magnetic member 132.

[0103] In some alternative embodiments, at least one of the first connector 140 and the second connector 150 is a sheet adhesive.

[0104] It should be noted that sheet adhesive is easy to apply, requiring only simple bonding steps to complete installation without complicated tools or equipment, thus simplifying the assembly process and improving production efficiency. Sheet adhesive provides uniform adhesion, ensuring a more even stress distribution between connectors and magnetic components, reducing localized stress concentrations, and extending the lifespan of the components.

[0105] It should be noted that, compared to mechanical connectors, sheet adhesives are generally less expensive, effectively reducing material and manufacturing costs and making the overall cost of the liquid cooling assembly 100 more competitive. Furthermore, sheet adhesives can be cut into different shapes and sizes to suit various design requirements and application scenarios.

[0106] Because sheet adhesive can completely cover the joint surface, it can effectively fill tiny gaps and unevenness, thereby improving sealing performance and preventing coolant leakage.

[0107] In addition, the adhesive has a certain degree of elasticity, which can provide a buffering effect when subjected to external impact or vibration, reduce direct damage to the liquid cooling component 100, and enhance the component's impact resistance.

[0108] Figure 2 This is a schematic diagram of the back structure of the liquid cooling plate in the liquid cooling assembly of this application embodiment. Figure 3 This is a schematic diagram of the structure of the liquid cooling component according to an embodiment of this application. Figure 4 for Figure 3 Sectional view of AA, Figure 5 for Figure 4 A magnified view of a section at point I. Figure 6 for Figure 3 A magnified view of a section at point B.

[0109] like Figures 1 to 6 As shown, in some optional embodiments, the liquid cooling assembly 100 further includes at least two limiting members 160;

[0110] At least two limiting members 160 are located at the edges of the upper plate 110 of the liquid cooling plate, and the at least two limiting members 160 form a limiting space so that the bottom plate 120 of the liquid cooling plate is located within the limiting space.

[0111] It should be noted that the limiting component 160 provides additional mechanical constraints to ensure that the liquid cooling plate base plate 120 maintains a stable position within the limiting space, preventing displacement or misalignment caused by external vibration or impact.

[0112] By setting limiters 160 around the perimeter, the lateral movement of the liquid cooling plate base plate 120 is restricted, ensuring that it always maintains the correct alignment and position during operation.

[0113] The limiting component 160 can reduce the relative movement between the liquid cooling plate base plate 120 and the upper plate, thereby protecting the integrity of the magnetic components and connectors and extending their service life.

[0114] In addition, the limiting space formed by the limiting component 160 can help to quickly align the liquid cooling plate base plate 120, simplify the assembly process, and improve assembly efficiency and accuracy.

[0115] In some embodiments, the design of the limiting member 160 can be adjusted according to different application requirements to accommodate different size and shape requirements, providing greater design flexibility.

[0116] In some embodiments, the limiting member 160 is L-shaped, and the two limiting members 160 are located at the two corners of the upper plate 110 of the liquid cooling plate.

[0117] In other embodiments, there may be four limiting members 160, with the four limiting members 160 located at the four corners of the upper plate 110 of the liquid cooling plate.

[0118] like Figures 1 to 6 As shown, in some optional embodiments, the limiting member 160 includes a first limiting edge 161 and a second limiting edge 162 connected together.

[0119] The first limiting edge 161 abuts against the first side edge of the liquid cooling plate base plate 120, and the second limiting edge 162 abuts against the second side edge of the liquid cooling plate base plate 120.

[0120] The first side and the second side of the liquid-cooled plate base plate 120 are two adjacent edges.

[0121] It should be noted that, through the interaction of the first limiting edge 161 and the second limiting edge 162, the liquid cooling plate base plate 120 can be precisely positioned within the limiting space, ensuring that it always maintains the correct position and alignment during operation.

[0122] The double-sided design of the limiting component 160 effectively restricts the movement of the liquid cooling plate base plate 120 in two adjacent directions, preventing displacement or misalignment caused by external vibration or impact.

[0123] The limiting design of adjacent edges provides additional mechanical support, enhances the structural stability of the liquid cooling plate base plate 120, and reduces deformation or damage caused by external forces.

[0124] When subjected to external impact, the double-sided design of the limiter 160 can provide additional support and cushioning, reducing direct damage to the internal structure of the liquid cooling system.

[0125] It should be noted that the shape and size of the limiting component 160 can be adjusted according to different application requirements to adapt to different liquid cooling plate size and shape requirements, providing greater design flexibility.

[0126] The liquid cooling assembly provided in this application includes an upper liquid cooling plate and a lower liquid cooling plate, which are detachably connected to the upper liquid cooling plate. The lower liquid cooling plate has a liquid cooling channel for the flow of coolant.

[0127] By designing the liquid cooling plate base plate and the liquid cooling plate upper plate as detachable, it is possible to quickly remove and repair or replace them if either one is damaged, reducing costs and allowing for timely replacement of damaged parts, thus extending the service life of the entire liquid cooling assembly.

[0128] In addition, this application embodiment also provides a CTP battery pack, including a housing, thermally conductive adhesive, battery cells, and the aforementioned liquid cooling assembly 100;

[0129] The enclosure has a receiving cavity for accommodating the battery cells and liquid cooling assembly 100;

[0130] The battery cell is attached to the liquid cooling assembly 100 via thermally conductive adhesive, and the liquid cooling assembly 100 is used to exchange heat with the battery cell.

[0131] In one possible implementation, the housing can be a rectangular structure, and the size of the housing can be greater than or equal to the size of the battery module, so that the housing can support the battery module.

[0132] The liquid cooling component 100 is in direct contact with the battery cell. Through the efficient heat transfer performance of the thermally conductive adhesive, the heat generated by the battery cell can be quickly conducted to the liquid cooling component 100, achieving efficient heat exchange, keeping the battery cell within the optimal operating temperature range, and improving the performance and lifespan of the battery pack.

[0133] The CTP design eliminates the traditional module structure, allowing cells to be arranged more closely together and increasing the energy density of the battery pack. Meanwhile, the integrated design of the liquid cooling component 100 also helps reduce the overall size and weight.

[0134] Through effective thermal management, the liquid cooling assembly 100 can prevent the battery cells from overheating, reduce the risk of thermal runaway, and improve the safety of the battery pack. In addition, the design of the limiting member 160 ensures the stability of the liquid cooling assembly 100 and the battery cells within the housing cavity, preventing displacement caused by vibration or impact.

[0135] The thermally conductive adhesive not only provides excellent thermal conductivity but also offers adhesion and cushioning, absorbing vibration and shock and protecting the structural integrity of the battery cell and liquid cooling assembly 100. Furthermore, the thermally conductive adhesive facilitates the replacement and maintenance of the liquid cooling plate 110.

[0136] Through effective thermal management, the battery pack can operate efficiently over a wider temperature range, reducing energy loss and improving overall energy efficiency.

[0137] It should be noted that the specific structure of the liquid cooling component 100 will not be limited here, but can be referred to the above.

[0138] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
