These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0040] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0041] The terms “first,” “second,” “third,” and “fourth,” etc. (if present), in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0042] As described in the background section, in related technologies, a battery pack has a mounting frame with mounting cavities. A liquid cooling plate, a heating film, and a crossbeam are disposed within the mounting cavity, with both the heating film and the crossbeam mounted on the liquid cooling plate. The crossbeam divides the mounting cavity into multiple cell cavities for mounting cell modules separately. Multiple clearance holes are provided on the crossbeam to allow the heating film to extend through these holes into the multiple cell cavities and connect with the cell modules within the corresponding cell cavities.

[0043] However, creating clearance holes in the crossbeam will result in insufficient stiffness of the crossbeam, affecting the overall stability of the battery pack structure.

[0044] For example, the crossbeam located in the middle area usually needs to have clearance holes so that the heating film can pass through the clearance holes into the next cell cavity, which will result in insufficient rigidity of the crossbeam located in the middle area.

[0045] To address the aforementioned problems in the prior art, this utility model provides a cold plate structure, a battery pack, and a vehicle. The cold plate structure includes a cold plate body with at least one mounting position for mounting a heating film, extending along the arrangement direction of multiple cells in the battery cell module. The cold plate body also has at least one clearance groove, which intersects with the mounting position. This clearance groove accommodates a portion of the heating film and corresponds to the crossbeam of the battery pack. By providing the clearance groove on the cold plate body and corresponding it to the crossbeam of the battery pack, the heating film can pass through the clearance groove from the bottom of the crossbeam into the next cell cavity and connect with the cell module in that cavity. This eliminates the need for clearance holes on the crossbeam, ensuring its rigidity and improving the overall stability of the battery pack structure.

[0046] The following describes exemplary application scenarios of this utility model.

[0047] The cold plate structure provided by this utility model can be applied to battery packs of new energy vehicles, such as pure electric vehicles, plug-in hybrid vehicles, and range-extended electric vehicles. Specifically, the cold plate structure provided by this utility model avoids the heating film by using avoidance grooves, thus eliminating the need to open avoidance holes on the crossbeam, ensuring the rigidity of the crossbeam and improving the overall stability of the battery pack structure.

[0048] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0049] Reference Figures 2 to 5 As shown in the embodiment of this application, the cold plate structure 10 includes a cold plate body 100.

[0050] The cold plate body 100 is provided with at least one mounting position for mounting the heating film 202, and the mounting position extends along the arrangement direction of multiple cells of the cell module. The cold plate body 100 is also provided with at least one clearance groove 101, which is cross-connected with the mounting position. The clearance groove 101 is used to accommodate part of the heating film 202 and is used to correspond to the crossbeam 203 of the battery pack.

[0051] It is understood that the cold plate structure 10 provided in this application embodiment can be used in the battery pack of new energy vehicles. The cold plate structure 10 can be connected to the liquid cooling device outside the battery pack. The liquid cooling device delivers refrigerant to the cold plate structure 10, and the refrigerant carries away the heat generated by the cell module, thereby achieving heat dissipation and cooling, and ensuring that the temperature of the cell module is kept within a safe range.

[0052] Reference Figure 1 and Figure 2 As shown, the battery pack has a mounting frame 201, and the cold plate structure 10 and the heating film 202 are both disposed within the mounting frame 201. By setting a crossbeam 203, the internal space of the mounting frame 201 is divided into multiple cell cavities 2011, and each cell cavity 2011 is provided with a cell module.

[0053] The heating film 202 of the battery pack can be arranged on the mounting position on the cold plate body 100, and both the mounting position and the heating film 202 extend along the arrangement direction of multiple cells of the cell module. This ensures that the heating film 202 takes into account all cells and prevents local overheating or uneven temperature.

[0054] Reference Figure 1 and Figure 2 As shown, the cold plate body 100 is provided with a clearance groove 101, which corresponds to the crossbeam 203. The heating film 202 can enter the next cell cavity 2011 from the bottom of the crossbeam 203 through the clearance groove 101 and connect with the cell module in the next cell cavity 2011. In this way, there is no need to open clearance holes on the crossbeam 203, which ensures the rigidity of the crossbeam 203 and improves the stability of the overall battery pack structure.

[0055] To facilitate understanding of the directions, an XY plane coordinate system is established in the accompanying drawings. The direction of the X-axis is the first direction in this application, and the direction of the Y-axis is the second direction in this application. The arrangement direction of the multiple cells of the battery module is the first direction, the extension direction of the heating film 202 is the first direction, and the extension direction of the clearance groove 101 is the second direction. The first direction and the second direction intersect.

[0056] It is understood that there is at least one mounting position, and the number of mounting positions can be one, two or more, as long as they correspond to the number of heating films 202 in the battery pack. There is at least one clearance groove 101, and the number of clearance grooves 101 can be one, two or more, as long as they correspond to the number of crossbeams 203 in the battery pack. This application embodiment does not impose too many restrictions on this.

[0057] In summary, the cold plate structure 10 provided in this application embodiment has a clearance groove 101 on the cold plate body 100, which corresponds to the crossbeam 203 of the battery pack. This allows the heating film 202 to enter the next cell cavity 2011 from the bottom of the crossbeam 203 through the clearance groove 101 and connect with the cell module in the next cell cavity 2011. This eliminates the need for clearance holes on the crossbeam 203, ensuring the rigidity of the crossbeam 203 and improving the overall stability of the battery pack structure.

[0058] Reference Figure 1 and Figure 2 As shown, in some embodiments, the extension direction of the mounting position is perpendicular to the extension direction of the clearance groove 101.

[0059] In the above embodiment, the extension direction of the mounting position is perpendicular to the extension direction of the clearance groove 101, that is, the first direction is perpendicular to the second direction, so as to make the overall structure more compact, reduce unnecessary gaps, and improve the space utilization rate inside the battery pack.

[0060] Reference Figure 2 As shown, in some embodiments, the clearance groove 101 extends from one side of the cold plate body 100 to the opposite side.

[0061] In the above embodiment, the clearance groove 101 extends through the entire cold plate body 100 along the second direction, which can provide more installation space for the heating film 202, enabling it to accommodate larger sizes or more numbers of heating films 202, making the installation of the heating film 202 easier, eliminating the need for repeated position adjustments, reducing installation time and possible operational errors.

[0062] Reference Figure 2 and Figure 4 As shown, in some embodiments, the clearance groove 101 has at least one rounded corner 102.

[0063] In the above embodiments, the design of the rounded corner 102 can avoid the problems of scratching and cutting of the heating film 202 during installation or use caused by sharp angles, thereby improving the overall durability of the heating film 202 and extending its service life.

[0064] Specifically, refer to Figure 4 As shown, both corners of the clearance groove 101 are designed with rounded corners 102.

[0065] Reference Figure 2 As shown, in some embodiments, there are multiple clearance grooves 101, and the multiple clearance grooves 101 are spaced apart along the extension direction of the mounting position.

[0066] In the above embodiment, a plurality of clearance grooves 101 are provided so that they can be correspondingly provided with a plurality of crossbeams 203 in the battery pack, and the plurality of clearance grooves 101 are spaced apart along the first direction.

[0067] The battery pack mounting frame 201 can be equipped with multiple crossbeams 203, which are spaced apart along a first direction. This allows the crossbeams 203 and the mounting frame 201 to form two or more cell cavities 2011, thereby enabling the battery pack to have a larger cell capacity.

[0068] Reference Figure 2 As shown, in some embodiments, there are multiple mounting positions, which are spaced apart along the extension direction of the clearance groove 101.

[0069] In the above embodiment, multiple mounting positions are provided so that multiple heating films 202 in the battery pack can be installed on the mounting positions accordingly, and the multiple mounting positions are spaced apart along the second direction.

[0070] The heating film 202 can be bonded to the mounting position via structural components.

[0071] Reference Figure 5 As shown, in some embodiments, a liquid cooling channel 200 is provided inside the cold plate body 100, and a connecting part 300 is provided on one side of the cold plate body 100. The connecting part 300 is provided with a liquid inlet and a liquid outlet, which are respectively connected to the liquid cooling channel 200.

[0072] In the above embodiment, the connecting part 300 can be used to connect to the liquid cooling device outside the battery pack. The liquid cooling device delivers refrigerant to the liquid cooling channel 200 through the liquid inlet. The refrigerant flows in the liquid cooling channel 200 and carries away the heat generated by the cell module. Then it flows back to the liquid cooling device through the liquid outlet.

[0073] Among them, reference Figure 1 , Figure 5 and Figure 6 As shown, the connecting part 300 can be used to install the connector 400. The connector 400 is provided with an inlet pipe 410 and an outlet pipe 420. The inlet pipe 410 is connected to the inlet port on the connecting part 300, and the outlet pipe 420 is connected to the outlet port on the connecting part 300. The connector 400 is connected to the liquid cooling device outside the battery pack through the inlet pipe 410 and the outlet pipe 420. In this way, the liquid cooling device outside the battery pack is connected to the liquid cooling channel 200 of the cold plate body 100 through the connector 400, so that the liquid cooling device can deliver refrigerant to the liquid cooling channel 200.

[0074] For example, the connector 400 can be installed on the connector 300 by welding or by fasteners such as bolts.

[0075] Furthermore, refer to Figure 1 and Figure 5 As shown, the connecting part 300 and the connector 400 can both be provided on the outside of the mounting frame 201, so as to facilitate the connection of the connector 400 with the liquid cooling device. This eliminates the need to make an opening in the side wall of the mounting frame 201, thereby reducing the installation and sealing procedures.

[0076] Reference Figure 2 and Figure 3As shown, in some embodiments, the cold plate body 100 includes a first housing portion 110 and a second housing portion 120, the first housing portion 110 and the second housing portion 120 being connected to form a liquid cooling channel 200.

[0077] The first housing portion 110 is provided with at least one first groove portion 111, and the second housing portion 120 is provided with at least one second groove portion 121. The first groove portion 111 and the second groove portion 121 are correspondingly provided to form an avoidance groove 101.

[0078] In the above embodiments, the liquid cooling channel 200 can be formed by connecting the first housing portion 110 and the second housing portion 120. The clearance groove 101 can be formed by correspondingly overlapping the first groove portion 111 on the first housing portion 110 and the second groove portion 121 on the second housing portion 120.

[0079] When the first housing part 110 is connected to the second housing part 120, the first groove part 111 and the second groove part 121 overlap accordingly, which can play a certain positioning role to avoid misalignment of the first housing part 110 and the second housing part 120 during installation.

[0080] The first housing portion 110 and the second housing portion 120 can be connected by welding.

[0081] Reference Figure 3 and Figure 5 As shown, in some embodiments, a liquid cooling groove 112 for forming a liquid cooling channel 200 is provided on the first housing portion 110, and a mounting position is provided on the second housing portion 120, which is used to connect with the heating film 202 and the battery cell module.

[0082] In the above embodiment, the liquid cooling groove 112 on the first housing part 110 and the second housing part 120 together form a liquid cooling channel 200, so that the surface of the second housing part 120 is flat, which facilitates the arrangement of the heating film 202 and the connection with the battery cell module.

[0083] The heating film 202 can be bonded to the second housing part 120 with structural adhesive. The battery module can also be bonded to the second housing part 120 with structural adhesive. This makes the surface of the second housing part 120 flat, reducing the bonding gap and improving the stability of the overall structural connection.

[0084] Reference Figure 3 and Figure 5As shown, in some embodiments, the liquid cooling channel 200 includes an inlet channel 210, an outlet channel 220, and at least one cooling channel 230. The inlet channel 210, the cooling channel 230, and the outlet channel 220 are connected in sequence. The inlet channel 210 is connected to the inlet, the outlet channel 220 is connected to the outlet, and the cooling channel 230 is configured to correspond to the battery cell module.

[0085] In the above embodiment, the refrigerant can enter the inlet channel 210 through the inlet port, and then flow into the cooling channel 230 through the inlet channel 210. The cooling channel 230 is set in correspondence with the battery cell module, so as to remove the heat generated by the battery cell module. Finally, it flows to the outlet port through the outlet channel 220.

[0086] Furthermore, refer to Figure 5 As shown, there are multiple cooling channels 230, which are connected to the inlet channel 210 and the outlet channel 220, respectively. In this way, the refrigerant in the inlet channel 210 can be divided into multiple refrigerant branches, which enter the multiple cooling channels 230 and then converge sequentially into the outlet channel 220. By setting up multiple cooling channels 230, it is possible to ensure coverage of all areas of the battery cell module, improve cooling efficiency, and thus avoid localized overheating.

[0087] Reference Figures 1 to 6 As shown, the battery pack provided in this application embodiment includes a battery pack body 20 and any of the above-mentioned cold plate structures 10, with the cold plate structure 10 disposed on the battery pack body 20.

[0088] The specific structure of the cold plate structure 10 has been described above and will not be repeated here. The battery pack body 20 is existing technology in the relevant technical field. It can be understood that the cold plate structure 10 provided in this application embodiment can be applied to any kind of battery pack body 20.

[0089] By using the aforementioned cold plate structure 10 inside the battery pack, the heating film 202 is avoided by the avoidance groove 101, thus eliminating the need to open avoidance holes on the crossbeam 203, ensuring the rigidity of the crossbeam 203, and improving the overall stability of the battery pack structure.

[0090] Reference Figure 1 and Figure 6 As shown, the battery pack body 20 includes a mounting frame 201 and a cell module, a heating film 202, and a crossbeam 203 disposed within the mounting frame 201. A cold plate structure 10 is disposed at the bottom of the mounting frame 201. The heating film 202 is laid on the cold plate structure 10. The crossbeam 203 is connected to the mounting frame 201 and is located above the clearance groove 101 of the cold plate structure 10. The cell module is disposed on the cold plate structure 10. The crossbeam 203 is located in the middle region of the mounting frame 201.

[0091] Furthermore, refer to Figure 1 and Figure 6 As shown, the battery pack body 20 also includes a side beam 204, which is disposed within the mounting frame 201. The side beam 204 is located near the end of the mounting frame 201 along a first direction, and divides the internal space of the mounting frame 201 into a first cavity 2012 and a second cavity 2013. A crossbeam 203 and a heating film 202 are both located within the first cavity 2012. The crossbeam 203 divides the first cavity 2012 into multiple cell cavities 2011 for mounting cell modules. The second cavity 2013 can be used to mount a battery management system, such as a Battery Disconnect Unit (BDU) or a Battery Management Unit (BMU).

[0092] The bottom of the side beam 204 may be provided with at least one through hole 2041, through which the wiring harness of the heating film 202 can extend into the first cavity 2012 for electrical connection with the battery management system.

[0093] In some embodiments, the heating film 202 can be bonded to the mounting position with structural adhesive, and the heating film 202 and the battery cell module can also be bonded with structural adhesive to avoid the heating film 202 falling off, which would affect the thermal management efficiency.

[0094] In some embodiments, the two ends of the crossbeam 203 can be connected to the inner wall of the mounting frame 201 by welding. In other embodiments, the two ends of the crossbeam 203 can also be fixed to the inner wall of the mounting frame 201 by fasteners such as bolts. In this way, there is a clearance gap between the crossbeam 203 and the clearance groove 101 to facilitate the passage of the heating film 202.

[0095] The vehicle provided in this application includes a vehicle body and a battery pack disposed on the vehicle body.

[0096] In the above structural configuration, since the vehicle uses the battery pack in the above embodiment, it also has the advantages and benefits brought by the battery pack, which will not be elaborated further here.
