[0003] Automotive battery modules are key components in electric vehicles or plug-in hybrid electric vehicles designed to store electrical energy. A battery module consists of multiple batteries connected in series and parallel to provide the required voltage and capacity.

[0004] When the battery in the related technology is set as a cylindrical battery, the positive and negative terminals of the battery are usually set at the two ends of the battery respectively. The cold plate of the thermal management system cannot effectively contact the end of the cylindrical battery, thereby reducing the cooling efficiency of the cold plate for the battery. Summary of the Invention

[0005] The following is a brief summary of the subject matter described in detail herein. This summary is not intended to limit the scope of the claims.

[0006] This application provides a battery cooling structure, a battery module, and an automobile.

[0007] In a first aspect, this application provides a battery cooling structure, including a cold plate and a battery. The cold plate is provided with at least one battery, and multiple batteries are provided on opposite sides of the cold plate. One end of the battery is provided as a cooling end, and the other end is provided as an electrical connection end. The battery has a positive electrode and a negative electrode, both of which are provided on the electrical connection end. The cooling end is attached to the cold plate, and the cold plate is configured to cool the battery through the cooling end.

[0008] In some embodiments, the battery is cylindrical, the cooling end is located at one end of the cylindrical battery along its axial direction, and the electrical connection end is located at the other end of the cylindrical battery along its axial direction.

[0009] In some embodiments, a refrigerant channel is provided inside the cold plate, and an inlet pipe and an outlet pipe are provided on the cold plate. The inlet pipe and the outlet pipe are respectively connected to both ends of the refrigerant channel, and the inlet pipe and the outlet pipe are located at the same end of the cold plate.

[0010] In some embodiments, the system further includes an inlet pipe and an outlet pipe, wherein a plurality of inlet pipes are connected to the inlet pipe and a plurality of outlet pipes are connected to the outlet pipe, and some of the inlet pipes and some of the outlet pipes are located on the same side of the cold plate as the inlet pipes and the outlet pipes.

[0011] In some embodiments, a limiting component is further included, which is disposed at one end of the cold plate and is configured to engage or disengage with the copper busbar of the battery module to limit or disengage the copper busbar.

[0012] In some embodiments, the limiting component includes a mounting plate and a snap-fit ​​plate. The mounting plate is connected to the cold plate. The snap-fit ​​plate is provided at both the upper and lower parts of the mounting plate. There is a snap-fit ​​space between the upper snap-fit ​​plate and the lower snap-fit ​​plate, which is configured to allow the copper busbar to move in or out, so that the snap-fit ​​plate snaps into or disengages from the copper busbar.

[0013] In some embodiments, the mounting plate includes a first connecting plate and a second connecting plate, with the second connecting plate disposed on both sides of the first connecting plate, and a fixing space between the two second connecting plates being configured to fix a portion of the cold plate.

[0014] In some embodiments, the snap-fit ​​plate includes a fixing plate and a snap-fit ​​block. The fixing plate is connected to the mounting plate. The snap-fit ​​block is disposed on the opposite surfaces of the upper and lower fixing plates.

[0015] Secondly, this application provides a battery module, including a frame and a battery cooling structure disposed within the frame.

[0016] Thirdly, this application provides an automobile, including a vehicle body and a battery cooling structure disposed on the vehicle body.

[0017] This application provides a battery cooling structure, a battery module, and an automobile. The battery cooling structure provided by this application employs a cooling end and an electrical connection end, and places both the positive and negative terminals of the battery at the electrical connection end. This allows the positive and negative terminals of the battery to be located at the same end of the battery. When the cooling end of the battery is in contact with the cold plate, the positive and negative terminals of the battery do not affect the contact between the cold plate and the cooling end of the battery, thereby increasing the contact area between the cold plate and the battery end and indirectly improving the cooling efficiency of the cold plate for the battery. By placing multiple batteries on opposite sides of the cold plate, the same cold plate can cool more batteries, thereby reducing the number of cold plates arranged in the battery module and indirectly reducing the space occupied by the entire battery module. Furthermore, by cooling more batteries with the cold plate, the cooling efficiency of the cold plate for multiple batteries is indirectly improved. And by placing both the positive and negative terminals of the battery at the electrical connection end at the same end of the battery, it is convenient to connect multiple batteries in series or parallel via wires.

[0030] 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.

[0031] As described in the background section, the battery module of the related technology includes a frame and multiple sets of battery cells arranged side by side along the width of the frame. Each set of battery cells includes multiple cylindrical batteries. In order to prevent the cylindrical batteries from overheating and affecting battery performance during use, the battery module also includes a thermal management system. The thermal management system includes a cold plate, which is disposed between two adjacent sets of battery cells. A refrigerant channel is provided inside the cold plate. One end of the cold plate is connected to the refrigerant channel via an inlet pipe, and the other end is connected to the refrigerant channel via an outlet pipe. By transporting the refrigerant along the inlet pipe into the refrigerant channel, the cold plate cools the cylindrical batteries. The refrigerant that has exchanged heat with the cylindrical batteries is discharged along the outlet pipe.

[0032] However, the positive and negative electrodes of a cylindrical battery are usually located at both ends of the battery. Because of the location of the positive and negative electrodes, the cold plate cannot effectively contact the ends of the cylindrical battery, thus reducing the cooling efficiency of the cold plate for the battery.

[0033] This application provides a battery cooling structure, a battery module, and an automobile. By arranging multiple batteries on opposite sides of a cold plate and placing the positive and negative terminals of the batteries on their electrical connection points, the cooling ends of the batteries can be in contact with the cold plate. In this case, the positive and negative terminals of the batteries are located away from the cold plate, preventing them from affecting the contact between the cold plate and the batteries. This increases the contact area between the cold plate and the battery ends, indirectly improving the cooling efficiency of the cold plate. By placing the inlet and outlet pipes on the same side of the cold plate, the space occupied by the inlet and outlet pipes is reduced, further reducing the space occupied by the battery module. By moving the copper busbar between the upper and lower fixing plates, the upper and lower locking blocks abut against the side of the copper busbar away from the mounting plate, fixing the copper busbar to the mounting plate and thus fixing it to the cold plate, indirectly improving the fixation effect of the copper busbar within the battery module frame.

[0034] 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.

[0035] Referring to Figures 1 to 4, a battery cooling structure includes a cold plate 100 and a battery 200. The cold plate 100 is provided with at least one battery, and multiple batteries 200 are provided on both opposite sides of the cold plate 100. One end of the battery 200 is provided as a cooling end 210, and the other end is provided as an electrical connection end 220. The battery 200 has a positive electrode 230 and a negative electrode 240, both of which are provided on the electrical connection end 220. The cooling end 210 is attached to the cold plate 100, and the cold plate 100 is configured to cool the battery 200 through the cooling end 210.

[0036] In this embodiment, two cold plates 100 are provided, which are parallel to each other and spaced apart. The multiple batteries 200 on both sides of the cold plate 100 are divided into an upper battery cell layer and a lower battery cell layer. The upper battery cell layer includes thirteen batteries 200 and the lower battery cell layer includes fourteen batteries 200. The multiple batteries 200 in the upper battery cell layer and the multiple batteries 200 in the lower battery cell layer are arranged alternately. The cooling end 210 of the battery 200 faces the cold plate 100, and the electrical connection end 220 of the battery 200 is away from the cold plate 100.

[0037] By adopting the above technical solution, using a cooling end 210 and an electrical connection end 220, and placing both the positive electrode 230 and the negative electrode 240 of the battery 200 at the electrical connection end 220, the positive electrode 230 and the negative electrode 240 of the battery 200 can be located at the same end of the battery 200. When the cooling end 210 of the battery 200 is in contact with the cold plate 100, the positive electrode 230 and the negative electrode 240 of the battery 200 will not affect the contact between the cold plate 100 and the cooling end 210 of the battery 200, thereby increasing the contact area between the cold plate 100 and the end of the battery 200, and indirectly improving the contact area between the cold plate 100 and the battery 200. Cooling efficiency; by arranging multiple batteries 200 on both opposite sides of the cold plate 100, the same cold plate 100 can cool more batteries 200, thereby reducing the number of cold plates 100 arranged in the battery module and indirectly reducing the space occupied by the entire battery module; and by cooling more batteries 200 with the cold plate 100, the cooling efficiency of the cold plate 100 for multiple batteries 200 is indirectly improved; and by arranging the positive terminal 230 and negative terminal 240 of the battery 200 on the same end of the electrical connection terminal 220, it is convenient to connect multiple batteries 200 in series or in parallel through wires.

[0038] Referring to Figures 1 to 4, the battery 200 is cylindrical in shape, with the cooling end 210 located at one end of the cylindrical battery 200 along its axial direction and the electrical connection end 220 located at the other end of the cylindrical battery 200 along its axial direction.

[0039] In this embodiment, the axis of the cylindrical battery 200 is perpendicular to the cold plate 100; in other embodiments, the battery 200 may also be arranged in a cuboid or other shapes.

[0040] By adopting the above technical solution, by setting the battery 200 to a cylindrical shape and setting the cooling end 210 at one end of the cylindrical battery 200 along its axial direction, the contact area between the cold plate 100 and the cylindrical battery 200 is increased compared to the method of attaching the cold plate 100 to the cylindrical surface of the cylindrical battery 200, thereby improving the cooling efficiency of the cold plate 100 on the cylindrical battery 200.

[0041] Referring to Figures 4 to 6, a refrigerant channel 110 is provided inside the cold plate 100, and an inlet pipe 120 and an outlet pipe 130 are provided on the cold plate 100. The inlet pipe 120 and the outlet pipe 130 are respectively connected to the two ends of the refrigerant channel 110, and the inlet pipe 120 and the outlet pipe 130 are located at the same end of the cold plate 100.

[0042] In this embodiment, the inlet pipe 120 and the outlet pipe 130 are disposed at the same end of the cold plate 100, and the inlet pipe 120 and the outlet pipe 130 are respectively disposed on both sides of the cold plate 100. The inlet pipe 120 is disposed at the lower part of one side of the cold plate 100, and the outlet pipe 130 is disposed at the upper part of the other side of the cold plate 100.

[0043] By adopting the above technical solution, when the battery 200 needs to be cooled by the cold plate 100, the refrigerant is transported to the refrigerant channel 110 along the liquid inlet pipe 120. When the refrigerant flows in the refrigerant channel 110, it carries away the heat of the battery 200. The heated refrigerant can flow out along the liquid outlet pipe 130. By adopting the configuration of the liquid inlet pipe 120, the refrigerant channel 110 and the liquid outlet pipe 130, the cooling efficiency of the battery 200 is indirectly improved. By setting the liquid inlet pipe 120 and the liquid outlet pipe 130 at the same end of the cold plate 100, compared with setting the liquid inlet pipe 120 and the liquid outlet pipe 130 at two ends of the cold plate 100 respectively, the space occupied by the liquid inlet pipe 120, the liquid outlet pipe 130 and the cold plate 100 is reduced, thereby making the structure of the battery module more compact and further reducing the space occupied by the battery module.

[0044] Referring to Figures 4 to 6, in this embodiment, the refrigerant channel 110 includes a lower liquid inlet channel 111 and an upper liquid outlet channel 112. The lower liquid inlet channel 111 is disposed at the lower part of the cold plate 100, and the upper liquid outlet channel 112 is disposed at the upper part of the cold plate 100. One end of the lower liquid inlet channel 111 is connected to the liquid inlet pipe 120, and the other end of the lower liquid inlet channel 111 is connected to the upper liquid outlet channel 112. The end of the upper liquid outlet channel 112 away from the lower liquid inlet channel 111 is connected to the liquid outlet pipe 130. The lower liquid inlet channel 111 and the lower liquid inlet channel 112 can be distributed in a serpentine manner at the lower and upper parts of the cold plate 100, or the lower liquid inlet channel 111 and the lower liquid inlet channel 112 can be configured as multiple microchannels distributed at the lower and upper parts of the cold plate 100.

[0045] By adopting the above technical solution, and by setting up the lower liquid inlet channel 111 and the lower liquid inlet channel 112, since the liquid inlet pipe 120 and the liquid outlet pipe 130 are both set at the same end of the cold plate 100, it is convenient for the refrigerant to enter the lower liquid inlet channel 111 from the liquid inlet pipe 120 at the bottom of the cold plate 100, and then enter the upper liquid outlet channel 112 along the lower liquid inlet channel 111, thereby flowing along the upper liquid outlet channel 112 to the liquid outlet pipe 130 at the top of the cold plate 100, and being discharged along the liquid outlet pipe 130. This facilitates the arrangement of the refrigerant channel 110 and further improves the cooling efficiency of the multiple batteries 200 in the upper and lower battery cell layers.

[0046] Referring to Figures 4 to 6, the battery cooling structure also includes an inlet pipe 300 and an outlet pipe 400. Multiple inlet pipes 120 are connected to the inlet pipe 300, and multiple outlet pipes 130 are connected to the outlet pipe 400. Some of the inlet pipes 300 and some of the outlet pipes 400 are located on the same side of the cold plate 100 as the inlet pipes 120 and the outlet pipes 130.

[0047] In this embodiment, one end of the liquid inlet pipe 300 and the liquid outlet pipe 400 extends toward the location of the electrical connection terminal 220 of the battery 200, and passes through and is fixedly connected to the frame 600 of the battery module, thereby facilitating the input of refrigerant along the liquid inlet pipe 300 and facilitating the collection of refrigerant in the liquid outlet pipe 400.

[0048] By adopting the above technical solution, and by using the liquid inlet connecting pipe 300, the refrigerant can simultaneously enter the liquid inlet pipes 120 of multiple cold plates 100 through the liquid inlet connecting pipe 300. This eliminates the need for separate pipes to supply refrigerant to each liquid inlet pipe 120, reducing the space occupied by the liquid inlet connecting pipe 300 and the multiple liquid inlet pipes 120. By allowing the refrigerant to enter multiple liquid inlet pipes 120 simultaneously, the temperature of the refrigerant in the multiple liquid inlet pipes 120 can be maintained at the same level, thereby indirectly improving the cooling efficiency of the cold plates 100 for the multiple batteries 200. Furthermore, by using the liquid outlet connecting pipe 400, the cooling efficiency of the multiple batteries 200 can be further improved. The refrigerant can simultaneously enter the outlet connecting pipe 400 through multiple outlet pipes 130, which facilitates the simultaneous collection of refrigerant from multiple cold plates 100. This eliminates the need for separate pipes to collect refrigerant from each outlet pipe 130, reducing the space occupied by the outlet connecting pipe 400 and the multiple outlet pipes 130. Furthermore, by arranging the inlet connecting pipe 300, outlet connecting pipe 400, inlet pipe 120, and outlet pipe 130 on the same side of the cold plate 100, the space occupied by the inlet connecting pipe 300, outlet connecting pipe 400, inlet pipe 120, and outlet pipe 130 is reduced, further reducing the space occupied by the battery module.

[0049] Referring to Figures 6 to 9, the battery cooling structure also includes a limiting component 500, which is disposed at one end of the cold plate 100. The limiting component 500 is configured to engage or disengage with the copper busbar 700 of the battery module to limit or disengage the copper busbar 700.

[0050] By adopting the above technical solution and using the limiting component 500, the cold plate 100 is located inside the battery module frame 600, which allows the cold plate 100 to fix the copper busbar 700 inside the battery module frame 600. This prevents the copper busbar 700 from shaking inside the battery module when the vehicle is in motion, and improves the fixing strength of the copper busbar 700 inside the battery module frame 600. By using a snap-fit ​​method, the convenience of fixing the copper busbar 700 and the cold plate 100 for the installer is improved.

[0051] Referring to Figures 6 to 9, the limiting component 500 includes a mounting plate 510 and a snap-fit ​​plate 520. The mounting plate 510 is connected to the cold plate 100. Snap-fit ​​plates 520 are provided at both the upper and lower parts of the mounting plate 510. A snap-fit ​​space 530 is provided between the upper snap-fit ​​plate 520 and the lower snap-fit ​​plate 520 for the copper busbar 700 to move into. The snap-fit ​​space 530 is configured to allow the copper busbar 700 to move in or out, so that the snap-fit ​​plate 520 snaps into or disengages from the copper busbar 700.

[0052] In this embodiment, the mounting plate 510 and the snap-fit ​​plate 520 are integrally formed. By integrating the mounting plate 510 and the snap-fit ​​plate 520, the strength of the entire limiting assembly 500 is improved, thereby indirectly improving the fixing strength of the limiting assembly 500 to the copper busbar 700. The mounting plate 510 is connected to the end of the cold plate 100 away from the liquid inlet pipe 120 and the liquid outlet pipe 130.

[0053] By adopting the above technical solution, when it is necessary to fix the copper busbar 700, the upper and lower snap-fit ​​plates 520 can snap into the copper busbar 700 within the snap-fit ​​space 530 between the upper and lower snap-fit ​​plates 520, thereby fixing the copper busbar 700 to the cold plate 100. By setting snap-fit ​​plates 520 at both the upper and lower parts of the mounting plate 510, the snap-fit ​​strength between the copper busbar 700 and the upper and lower snap-fit ​​plates 520 is improved, thereby further improving the fixing strength of the copper busbar 700 to the cold plate 100. By setting the mounting plate 510, the snap-fit ​​plates 520 can be fixed to the cold plate 100, indirectly improving the fixing strength of the snap-fit ​​plates 520.

[0054] Referring to Figures 6 to 9, the mounting plate 510 includes a first connecting plate 511 and a second connecting plate 512. The second connecting plate 512 is provided on both sides of the first connecting plate 511, and there is a fixing space 513 between the two second connecting plates 512, which is used to fix a portion of the cold plate 100.

[0055] In this embodiment, a mounting sleeve 140 is fitted and fixedly connected to the end of the cold plate 100 away from the liquid inlet pipe 120 and the liquid outlet pipe 130. The mounting sleeve 140 has recesses 141 on both sides and at the lower part of the mounting sleeve 140 to accommodate the battery 200 of the lower cell layer. Two second connecting plates 512 are provided, and the two second connecting plates 512 are respectively located on both sides of the first connecting plate 511. The second connecting plates 512 are parallel to the cold plate 100 and perpendicular to the cold plate 100. The first connecting plate 511 and the two second connecting plates 512 are arranged in a "U" shape. The "U"-shaped first connecting plate 511 and second connecting plate 512 are fitted and fixedly connected to the mounting sleeve 140. The mounting plate 510 is connected to the cold plate 100 through the mounting sleeve 140.

[0056] By adopting the above technical solution, and by using the first connecting plate 511 and the second connecting plate 512, the first connecting plate 511 can be connected to the edge of the cold plate 100, and the two second connecting plates 512 can be connected to the opposite sides of the cold plate 100. This increases the contact area between the mounting plate 510 and the cold plate 100, improves the fixing strength between the mounting plate 510 and the cold plate 100, and indirectly improves the fixing strength of the copper busbar 700 on the cold plate 100.

[0057] Referring to Figures 6 to 9, the snap-fit ​​plate 520 includes a fixing plate 521 and a snap-fit ​​block 522. The fixing plate 521 is connected to the mounting plate 510. The snap-fit ​​block 522 is disposed on the opposite surfaces of the upper fixing plate 521 and the lower fixing plate 521. The snap-fit ​​block 522 is located away from the mounting plate 510 and is configured to abut against the side of the copper busbar 700 away from the mounting plate 510.

[0058] In this embodiment, two fixing plates 521 are provided, which are respectively located on the upper and lower parts of the first connecting plate 511 and are arranged parallel to each other. The surface of the snap-fit ​​block 522 facing away from the first connecting plate 511 is set as an inclined surface. The distance between the upper and lower inclined surfaces gradually decreases in the direction towards the first connecting plate 511, so as to facilitate the copper busbar 700 to be moved into the snap-fit ​​space 530 along the inclined surface. The surface of the snap-fit ​​block 522 facing the first connecting plate 511 is perpendicular to the fixing plate 521, thereby improving the snap-fit ​​strength between the snap-fit ​​block 522 and the copper busbar 700.

[0059] By adopting the above technical solution, when the copper busbar 700 moves toward the snap-fit ​​space 530, the copper busbar 700 can abut against the snap-fit ​​block 522, thereby causing the upper snap-fit ​​block 522 and the lower snap-fit ​​block 522 to move away from each other. At this time, the copper busbar 700 can move past the snap-fit ​​block 522 to the space between the upper fixing plate 521 and the lower fixing plate 521. The snap-fit ​​block 522 can abut against the side of the copper busbar 700 away from the mounting plate 510, thereby fixing the copper busbar 700 between the upper fixing plate 521 and the lower fixing plate 521. The copper busbar 700 can be fixed by moving it between the upper and lower fixing plates 521. The fixing method is convenient and simple, improving the convenience of fixing the copper busbar 700.

[0060] This application also provides a battery module, including a frame 600 and a battery cooling structure of any of the above embodiments disposed within the frame 600.

[0061] The specific structure of the battery cooling structure has been described in detail in the above embodiments and will not be repeated here.

[0062] This application also provides an automobile, including a vehicle body and a battery cooling structure of any of the above embodiments disposed on the vehicle body.

[0063] The specific structure of the battery cooling structure has been described in detail in the above embodiments and will not be repeated here.

[0064] The automobile provided in this application embodiment, by setting a battery cooling structure, arranges multiple batteries 200 on both sides opposite to the cold plate 100, and positions the positive electrode 230 and negative electrode 240 of the battery 200 on the electrical connection terminal 220 of the battery 200, so that the cooling end 210 of the battery 200 can be in contact with the cold plate 100. At this time, the positive electrode 230 and negative electrode 240 of the battery 200 can be located at the end away from the cold plate 100, thereby preventing the positive electrode 230 and negative electrode 240 of the battery 200 from affecting the contact between the cold plate 100 and the battery 200, thereby increasing the contact area between the end of the cold plate 100 and the battery 200, and indirectly improving the cooling efficiency of the cold plate 100 for the battery 200; by using an inlet connecting pipe The liquid inlet pipe 300, liquid outlet pipe 400, liquid inlet pipe 120, and liquid outlet pipe 130 are all located on the same side of the cold plate 100, thereby reducing the space occupied by the liquid inlet pipe 300, liquid outlet pipe 400, liquid inlet pipe 120, and liquid outlet pipe 130, and further reducing the space occupied by the battery module; by moving the copper busbar 700 between the upper fixing plate 521 and the lower fixing plate 521, the upper snap-fit ​​block 522 and the lower snap-fit ​​block 522 abut against the side of the copper busbar 700 away from the mounting plate 510, thereby fixing the copper busbar 700 on the mounting plate 510 and fixing the copper busbar 700 on the cold plate 100, thereby indirectly improving the fixing effect of the copper busbar 700 in the frame 600 of the battery module.
