[0031] In the description of this application, it should be noted that, unless otherwise explicitly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0032] The technical solution of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this application, not all embodiments.

[0033] The following is for reference. Figures 1 to 5 This invention describes a battery cooling system, a battery, and an electric two-wheeler according to embodiments of the present invention.

[0034] like Figure 1 As shown, Figure 1 This is a system diagram of a battery heat dissipation system according to an embodiment of the present invention. The battery heat dissipation system includes:

[0035] The housing 400 has multiple through holes on its sidewalls;

[0036] A heat dissipation component is disposed within the housing 400. The heat dissipation component has multiple heat sinks 202 on its periphery, and the multiple heat sinks 202 are respectively disposed through multiple through holes. The battery cell module is disposed on the heat dissipation component and located within the housing 400.

[0037] A heat-conducting structure is installed on the vehicle body, with one end of the heat-conducting structure abutting against multiple heat sinks 202;

[0038] The heat dissipation unit 800 is installed on the vehicle body and is used to dissipate heat from the heat conduction structure.

[0039] In this embodiment of the application, by setting a heat dissipation component, the heat inside the battery casing 400 can be discharged from the heat dissipation component, and the heat discharged by the battery heat dissipation component can be discharged from the battery compartment through the heat conduction structure. This can effectively reduce the adverse effects of the enclosed space on battery heat dissipation. Furthermore, the heat dissipation unit 800 is used to dissipate heat from the heat conduction structure, which further accelerates the heat exchange efficiency of the heat conduction structure, thereby effectively reducing the risk of fire in high-temperature environments.

[0040] refer to Figures 2 to 5 The aforementioned battery cell module can be installed inside the housing 400 and can be attached to the upper surface of the heat-conducting base plate 100 of the heat dissipation assembly.

[0041] refer to Figures 2 to 5 The multiple heat sinks 202 provided in the above-mentioned heat dissipation component can pass through multiple through holes in the housing 400 and thus come into contact with the heat-conducting structure, thereby transferring heat to the heat-conducting structure.

[0042] The above-mentioned heat-conducting structure can be provided with multiple abutment parts at one end near the battery compartment. These multiple abutment parts abut against multiple heat sinks 202, thereby achieving heat conduction of the heat sinks 202. It can be understood that the larger the contact area between the heat sinks 202 and the abutment parts, the higher the heat conduction efficiency.

[0043] The end of the aforementioned heat-conducting structure furthest from the battery compartment can extend to both sides under the vehicle seats, facilitating the installation of the heat dissipation unit 800. The heat dissipation unit 800 then rapidly dissipates heat from the heat-conducting structure. It should be noted that heat dissipation vents can be provided on the vehicle body shell at the locations corresponding to the heat dissipation unit 800, enabling efficient heat dissipation from the heat dissipation unit 800.

[0044] The aforementioned heat-conducting structure can be made of metal or other materials with high thermal conductivity to improve heat conduction efficiency.

[0045] In some implementations, reference Figure 1 The battery cooling system also includes:

[0046] Temperature detection unit 510 is used to detect the temperature of the battery cell module;

[0047] The control unit 520 is mounted on the vehicle body and is electrically connected to the temperature detection unit 510 and the heat dissipation unit 800, respectively.

[0048] In this embodiment, the temperature detection unit 510 can be set to detect the temperature of the battery cell module, so that the control unit 520 can adjust the heat dissipation power of the heat dissipation unit 800 according to the battery cell temperature detected by the temperature detection unit 510, so as to achieve a balance between heat dissipation and energy saving.

[0049] The temperature detection unit 510 includes at least one temperature sensor, which is disposed on the outer surface of the cell module and / or on the inner surface of the housing 400, thereby realizing the detection of the cell temperature.

[0050] The control unit 520 mentioned above can be the main controller carried by the electric two-wheeler itself, or a separate independent main controller can be set up.

[0051] In some implementations, reference Figure 1 The battery cooling system also includes:

[0052] The display unit 610 is located on the front of the vehicle body and is electrically connected to the control unit 520.

[0053] In this embodiment, the display unit 610 enables real-time monitoring of the cell temperature, allowing for early detection of significant temperature abnormalities and preventing users from being informed only after the cell module catches fire, thereby reducing personal and property losses caused by fire.

[0054] In some implementations, the temperature data detected by the temperature detection unit 510 is compared with a preset temperature threshold to determine whether overheating has occurred. Then, a warning message can be sent through the display unit 610 to effectively inform the user of the danger and prevent the user from not being aware of the danger in time.

[0055] In some implementations, reference Figure 1 The battery cooling system also includes:

[0056] The audible and visual alarm unit 620 is installed on the vehicle body and is electrically connected to the control unit 520.

[0057] In this embodiment, the sound and light alarm unit 620 can be used to provide sound and light alarms, thereby avoiding the situation where the user cannot detect the alarm in time when the display unit 610 is used to display the alarm.

[0058] In some implementations, reference Figure 1 The battery cooling system also includes:

[0059] The communication module 700 is mounted on the vehicle body and is electrically connected to the control unit 520.

[0060] In this embodiment, the communication module 700 can transmit local temperature information, alarm information and other information to a remote location for remote monitoring. This also facilitates timely notification in case of an emergency, enabling a rapid response and minimizing personal and property losses.

[0061] In some embodiments, the heat dissipation unit 800 includes:

[0062] A semiconductor cooling chip, electrically connected to the control unit 520, is used to dissipate heat from the heat-conducting structure;

[0063] The cooling fan, electrically connected to the control unit 520, is used to deliver the heat generated by the semiconductor cooling chip to the outside of the vehicle.

[0064] The cooling side of the aforementioned thermoelectric cooler can be bonded to the heat-conducting structure with thermally conductive adhesive, thereby directly and effectively cooling the heat-conducting structure. In particular, compared to the heat-conducting structure passively conducting heat through a cooling fan, the cooling efficiency is higher. At the same time, by placing a cooling fan on the heat-dissipating side of the thermoelectric cooler, the heat generated by the thermoelectric cooler during the cooling process can be conducted to the outside of the vehicle.

[0065] The cooling side of the aforementioned thermoelectric cooler faces the vehicle body, while the heating side faces the vehicle body. A through hole is provided on the vehicle body shell corresponding to the cooling side of the thermoelectric cooler to facilitate rapid heat dissipation by the fan.

[0066] In some implementations, reference Figures 2 to 4 The heat dissipation components include:

[0067] A heat-conducting base plate 100 is provided, and at least one heat-conducting connecting plate 101 is connected to the edge of the heat-conducting base plate 100. The heat-conducting connecting plate 101 extends along the edge of the heat-conducting base plate 100 to which it is connected, and the heat-conducting connecting plate 101 is provided with a plurality of clearance openings 102. The battery cell module is disposed on the heat-conducting base plate 100.

[0068] At least one heat sink 200, the heat sink 200 includes a heat sink connecting plate 201 and a plurality of heat sinks 202, the heat sink connecting plate 201 is attached to the inner side of the heat conduction connecting plate 101 and is detachably connected to the heat conduction connecting plate 101, the plurality of heat sinks 202 are disposed on the outer side of the heat sink connecting plate 201 and are respectively inserted through a plurality of relief openings 102.

[0069] At least one thermally conductive connecting plate 101 is connected to the edge of the aforementioned thermally conductive base plate 100. For example, four thermally conductive connecting plates 101 may be provided, with each of the four thermally conductive connecting plates 101 connected to the four perimeters of the thermally conductive base plate 100. The thermally conductive connecting plate 101 extends along the edge of the thermally conductive base plate 100 to which it is connected, for example, it may extend to both ends of the edge of the thermally conductive base plate 100 to which it is connected. The thickness direction of the thermally conductive connecting plate 101 may be parallel to the edge of the thermally conductive base plate 100 to which it is connected. For example, when the thermally conductive base plate 100 is attached to the bottom of the housing 400, the thickness direction of the thermally conductive connecting plate 101 may be parallel to the thickness direction of the corresponding sidewall of the housing 400. The heat-conducting connecting plate 101 is provided with multiple clearance openings 102, which can be arranged along the length direction of the heat-conducting connecting plate 101 and can penetrate along the thickness direction of the heat-conducting connecting plate 101. When the heat-conducting base plate 100 is attached to the bottom end inside the housing 400, the clearance openings 102 can be aligned with the through holes on the corresponding side wall of the housing 400. When the battery cell module is placed inside the housing 400, the battery cell module can be attached to the upper surface of the heat-conducting base plate 100 to facilitate the transfer of heat to the heat-conducting base plate 100.

[0070] The aforementioned heat sink 200 is provided at least once. For example, when four heat-conducting connecting plates 101 are provided, the four heat sinks 200 can be respectively provided for the four heat-conducting connecting plates 101. The heat sink 200 includes a heat sink connecting plate 201 and a plurality of heat sinks 202. The heat sink connecting plate 201 is attached to the inner side of the corresponding heat-conducting connecting plate 101 and is detachably connected to the heat-conducting connecting plate 101. For example, the heat sink connecting plate 201 can be connected to or snapped onto the heat-conducting connecting plate 101 by fasteners 203. The plurality of heat sinks 202 are provided on the outer side of the heat sink connecting plate 201 and are respectively provided through a plurality of relief openings 102 and through through holes on the corresponding side wall of the housing 400.

[0071] It should be noted that the inner surface of the heat-conducting connecting plate 101, the inner surface of the heat-dissipating connecting plate 201, and the inner surface of the housing 400 refer to the surface facing the battery cell module after the battery cell module is placed inside the housing 400. The outer surface of the heat-conducting connecting plate 101, the outer surface of the heat-dissipating connecting plate 201, and the outer surface of the housing 400 refer to the surface facing away from the battery cell module after the battery cell module is placed inside the housing 400.

[0072] In this embodiment, when assembling the battery, firstly, the heat-conducting base plate 100 of the heat dissipation component is attached to the bottom surface inside the battery housing 400. Then, the heat dissipation component 200 is moved above the heat-conducting base plate 100, and the surface of the heat dissipation connecting plate 201 is made parallel to the surface of the heat-conducting connecting plate 101, so that multiple heat dissipation fins 202 are aligned with multiple clearance openings 102. Then, the heat dissipation component 200 is moved outward so that the heat dissipation connecting plate 201 is attached to the inner side surface of the heat-conducting connecting plate 101, and multiple heat dissipation fins 202 are respectively inserted through multiple clearance openings 102 and multiple through holes on the side wall of the housing 400. Finally, the heat dissipation connecting plate 201 is connected to the heat-conducting connecting plate 101. The operation is simple, time-saving and labor-saving.

[0073] In some implementations, reference Figures 2 to 4 The heat dissipation components also include:

[0074] At least one thermally conductive side plate 300 is connected to the top of the thermally conductive connecting plate 101. The outer side of the thermally conductive side plate 300 is used to fit the inner side of the battery casing 400, and the inner side of the thermally conductive side plate 300 is used to fit the outer side of the cell module.

[0075] In this embodiment, when four heat-conducting connecting plates 101 are provided and the four heat-conducting connecting plates 101 are respectively connected to the four periphery of the heat-conducting base plate 100, the four heat-conducting side plates 300 can also be provided and the four heat-conducting side plates 300 can be respectively located at the four periphery of the heat-conducting base plate 100, and the four heat-conducting side plates 300 are respectively connected to the top of the four heat-conducting connecting plates 101.

[0076] In this embodiment, a heat-conducting side plate 300 is provided, which can transfer the heat of the battery cell module from the periphery of the battery cell module to the heat-conducting side plate 300, and then part of it is transferred to the heat-conducting connecting plate 101 and dissipated through the heat sink 200, and part of it is directly transferred to the side wall of the housing 400 and dissipated through the side wall of the housing 400, so that the heat dissipation effect of the battery is better.

[0077] It should be noted that the heat-conducting base plate 100, heat-conducting side plate 300, heat-conducting connecting plate 201 and heat sink 202 of the heat dissipation component can all be made of heat-conducting materials, which will not be described in detail here.

[0078] In some implementations, such as Figures 2 to 5 As shown, a plurality of first heat dissipation grooves 301 are formed on the outer side of the heat-conducting side plate 300. The plurality of first heat dissipation grooves 301 are arranged at intervals along the length direction of the heat-conducting connecting plate 101, and the top of the first heat dissipation grooves 301 is provided through.

[0079] In this embodiment, multiple first heat dissipation grooves 301 can be directly formed on the outer surface of the heat-conducting side plate 300, or the heat-conducting side plate 300 can be configured as a bent plate structure, with the first heat dissipation grooves 301 formed by bending. In this embodiment, by providing multiple first heat dissipation grooves 301, some of the heat between the heat-conducting side plate 300 and the side wall of the housing 400 can be conducted through the airflow within the first heat dissipation grooves 301, thereby improving the heat dissipation effect of the heat dissipation component.

[0080] In some implementations, such as Figures 2 to 5 As shown, multiple first heat dissipation slots 301 are located above multiple relief openings 102, and the bottom end of the first heat dissipation slots 301 is connected to the relief openings 102.

[0081] The bottom end of the first heat dissipation groove 301 can be through-hole, and the top end of the relief opening 102 can be through-hole, so that the bottom end of the first heat dissipation groove 301 is connected to the relief opening 102.

[0082] In this embodiment, the bottom end of the first heat dissipation groove 301 is connected to the relief opening 102, which makes the flow of hot air in the first heat dissipation groove 301 better, and the hot air in the first heat dissipation groove 301 can flow directly to the relief opening 102 at the bottom end of the first heat dissipation groove 301 and be directly absorbed by the heat sink 202, thereby making the heat dissipation effect of the heat dissipation component better.

[0083] In some implementations, such as Figures 2 to 5 As shown, a plurality of second heat dissipation grooves 302 are formed on the inner side of the heat-conducting side plate 300. The plurality of second heat dissipation grooves 302 are arranged at intervals along the length direction of the heat-conducting connecting plate 101, and the top of the second heat dissipation grooves 302 penetrates through.

[0084] In this embodiment, multiple second heat dissipation grooves 302 can be directly formed on the inner surface of the heat-conducting side plate 300, or the heat-conducting side plate 300 can be configured as a bent plate structure, with the second heat dissipation grooves 302 formed by bending. In this embodiment, by providing multiple second heat dissipation grooves 302, some of the heat between the heat-conducting side plate 300 and the outer surface of the battery cell module can be conducted through the airflow within the second heat dissipation grooves 302, thereby improving the heat dissipation effect of the heat dissipation component.

[0085] In some implementations, such as Figures 2 to 5 As shown, the inner side of the heat-conducting side plate 300 protrudes from the inner side of the heat-conducting connecting plate 101, and the bottom end of the second heat dissipation groove 302 is through it.

[0086] The inner side of the aforementioned heat-conducting side plate 300 protrudes beyond the inner side of the heat-conducting connecting plate 101, facilitating the penetration of the bottom end of the second heat dissipation groove 302.

[0087] In this embodiment, the bottom end of the second heat dissipation groove 302 is through-hole, which makes the flow of hot air in the second heat dissipation groove 302 better, and the hot air in the second heat dissipation groove 302 can flow to the vicinity of the heat-conducting base plate 100 and be absorbed by the heat-conducting base plate 100, thereby making the heat dissipation effect of the heat dissipation component better.

[0088] It should be noted that the inner side of the heat-conducting side plate 300 protrudes beyond the inner side of the heat-conducting connecting plate 101, that is, the projection along the length direction of the heat-conducting connecting plate 101. The inner side of the heat-conducting side plate 300 is located directly above the inner side of the inner side of the heat-conducting connecting plate 101.

[0089] In some implementations, such as Figures 2 to 5 As shown, the inner side of the heat-conducting side plate 300 protrudes beyond the inner side of the heat dissipation connecting plate 201.

[0090] In this embodiment, the heat dissipation connecting plate 201 is positioned between the bottom surface of the heat-conducting side plate 300 and the top surface of the heat-conducting base plate 100, thereby preventing the battery cell module from touching the heat dissipation connecting plate 201 and damaging the battery cell module and the heat dissipation connecting plate 201. In addition, there is a certain heat dissipation space inside the heat dissipation connecting plate 201, which makes the heat dissipation effect of the heat dissipation component better.

[0091] It should be noted that the inner side of the heat-conducting side plate 300 protrudes beyond the inner side of the heat dissipation connecting plate 201, that is, the projection along the length of the heat-conducting connecting plate 101. The inner side of the heat-conducting side plate 300 is located directly above the inner side of the heat dissipation connecting plate 201.

[0092] In some implementations, such as Figure 2 and Figure 3 As shown, the first heat dissipation groove 301 and the second heat dissipation groove 302 are arranged alternately along the length of the heat-conducting connecting plate 101. This arrangement can prevent the heat-conducting side plate 300 from being too thin at a certain position, thus reducing the structural strength and minimizing the risk of damage to the heat-conducting side plate 300.

[0093] In some implementations, such as Figures 2 to 5 As shown, four heat-conducting connecting plates 101 are provided and located on the four periphery of the heat-conducting base plate 100, and four heat sinks 200 are provided accordingly. The heat sink connecting plate 201 of each heat sink 200 is respectively attached to the inner side of each heat-conducting connecting plate 101. In this embodiment, this arrangement makes the heat conduction and heat dissipation effect of the heat dissipation component better.

[0094] This utility model embodiment also provides a battery, which includes the battery heat dissipation system described above.

[0095] In this embodiment, by using the heat dissipation component of this utility model, when assembling the battery, firstly, the heat-conducting base plate 100 of the heat dissipation component is attached to the bottom surface inside the battery housing 400. Then, the heat dissipation component 200 is moved above the heat-conducting base plate 100, and the surface of the heat dissipation connecting plate 201 is made parallel to the surface of the heat-conducting connecting plate 101, so that multiple heat dissipation fins 202 are aligned with multiple clearance openings 102. Then, the heat dissipation component 200 is moved outward so that the heat dissipation connecting plate 201 is attached to the inner side surface of the heat-conducting connecting plate 101, and multiple heat dissipation fins 202 are respectively inserted through multiple clearance openings 102 and multiple through holes on the side wall of the housing 400. Finally, the heat dissipation connecting plate 201 and the heat-conducting connecting plate 101 are connected. The operation is simple, time-saving and labor-saving.
