[0051] Please refer to Figure 1 and Figure 2 , the electronic device 100 of the embodiment of this application includes a control device 30. It should be noted that, in some embodiments, the electronic device 100 can include but is not limited to an energy storage cabinet, a battery pack, a vehicle, a drone, etc. Exemplarily, when the electronic device 100 is an energy storage cabinet, the energy storage cabinet can include at least one battery pack, and the control device 30 is electrically connected to the battery pack and can control the operation of the battery pack. In the embodiment of this application, the electronic device 100 is taken as an energy storage cabinet as an example for illustration.

[0052] Furthermore, please combine Figure 2, in some embodiments, the electronic device 100 further includes a cabinet 10 and a battery cluster 20. The cabinet 10 is provided with a receiving cavity 11. The battery cluster 20 is disposed in the receiving cavity 11 and includes at least one battery pack 21. The control device 30 is disposed in the receiving cavity 11 and is electrically connected to the battery cluster 20. The control device 30 is configured to control the operation of the battery cluster 20. In the height direction Z of the cabinet 10, the control device 30 is located at the top of the battery cluster 20.

[0053] Among them, the cabinet 10 is a structure in the electronic device 100 that can accommodate and protect devices such as the battery cluster 20 and the control device 30. The cross-sectional shape of the cabinet 10 includes but is not limited to circular, square, triangular, or elliptical, etc. The material of the cabinet 10 includes but is not limited to plastic, aluminum alloy, copper, iron, steel, or carbon fiber composite material, etc. Exemplarily, the material of the cabinet 10 is aluminum alloy, so that it can be more lightweight while ensuring the stiffness of the cabinet 10, which is convenient for transportation.

[0054] The battery cluster 20 is an aggregate composed of multiple energy-storing battery packs 21. This aggregate can achieve energy storage and release by connecting and controlling the battery cells 213 in the battery packs 21. The cross-sectional shape of the battery cluster 20 is substantially the same as the cross-sectional shape of the cabinet 10, which can facilitate the installation and storage of the battery cluster 20 in the cabinet 10 and improve space utilization. The functions of the battery cluster 20 include but are not limited to energy storage, energy dispatching, and energy storage power stations, etc. Specifically, in some applications, the battery cluster 20 can convert electrical energy into chemical energy for storage to meet the electricity demand during peak energy demand periods, thereby playing the role of energy storage. In other applications, the battery cluster 20 can flexibly adjust the supply and demand of electrical energy to achieve energy balance and dispatching, improve energy utilization efficiency, and thus play the role of energy dispatching. In still other applications, the battery cluster 20 can form an energy storage power station to store and dispatch energy on a large scale and provide a reliable energy supply, thereby playing the role of an energy storage power station. It can be understood that the battery cluster 20 includes at least one, and the number of battery clusters 20 can be adaptively adjusted according to the application scenario and capacity of the electronic device 100.

[0055] The battery pack 21 is an aggregate composed of multiple energy-storing battery cells 213, and the battery cell 213 is the smallest unit for storing and releasing electrical energy. The battery pack 21 includes a case 211 and the battery cells 213 accommodated in the case 211. The case 211 of the battery pack 21 is made of insulating material, and the interior of the battery pack 21 is filled with an insulating and non-flammable liquid, effectively preventing problems such as thermal runaway, fire or explosion of the battery cells 213. The aggregate composed of the battery cells 213 can store and release energy by connecting and controlling the battery cells 213. In the battery pack 21, there are multiple battery cells 213, and the multiple battery cells 213 can be connected in series, in parallel or in a combination of series and parallel. The combination of series and parallel means that there are both series and parallel connections among the multiple battery cells 213. The multiple battery cells 213 can be directly connected in series, in parallel or in a combination of series and parallel together, and then the whole formed by the multiple battery cells 213 is accommodated in the case 211 of the battery pack 21. The battery pack 21 may further include other structures. For example, the battery pack 21 may further include a busbar component (not shown in the figure) for realizing the electrical connection among the multiple battery cells 213. It can be understood that the number of the battery cells 213 in the battery pack 21 can be adaptively adjusted according to the application scenario and capacity of the battery cluster 20.

[0056] In some embodiments, the electronic device 100 further includes a circuit assembly 60. The circuit assembly 60 connects adjacent battery packs 21, and the circuit assembly 60 also connects the battery pack 21 and the control device 30. Specifically, in the case where the battery cluster 20 includes multiple battery packs 21, the multiple battery packs 21 can be stacked in the height direction Z of the cabinet 10 in the accommodation cavity 11. The circuit assembly 60 includes multiple first cables 61, and the multiple first cables 61 can connect the multiple battery packs 21 in series and jointly form the battery cluster 20. The circuit assembly 60 further includes a second cable 63 and a third cable 65. One end of the second cable 63 is electrically connected to the positive terminal bus formed by connecting the multiple battery packs 21 in series, and the other end is electrically connected to the control device 30. One end of the third cable 65 is electrically connected to the negative terminal bus formed by connecting the multiple battery packs 21 in series, and the other end is electrically connected to the control device 30, so that the electrical energy of the battery cluster 20 can be transmitted to the outside through the control device 30; or the external electrical energy can be introduced into the battery cluster 20 through the control device 30.

[0057] The control device 30 is a device in the electronic device 100 for managing the battery cluster 20. The functions of the control device 30 include but are not limited to managing the charging and discharging of the battery cluster 20, managing and optimizing the energy usage of the battery cluster 20, and monitoring parameters such as the voltage, current and temperature of the battery cluster 20. Among them, the setting of the control device 30 can effectively manage and protect the operation of the battery cluster 20, ensuring the stability and reliability of the operation of the electronic device 100.

[0058] Further, in the height direction Z of the cabinet 10, the control device 30 is located at the top of the battery cluster 20. In other words, the control device 30 is disposed in the accommodation cavity 11 and is located at the uppermost position of the battery cluster 20 in the height direction Z of the cabinet 10. Thus, compared with the control device 30 being disposed outside the cabinet 10, on the one hand, the wiring connection between the control device 30 and the battery cluster 20 is more convenient and the wiring is shorter. Therefore, not only can the loss of electric energy during transmission be reduced, the overall efficiency be improved, but also the occurrence of inductive current and heat dissipation problems between cables can be prevented, ensuring the stability and reliability of the operation of the electronic device 100. On the other hand, the layout of the entire electronic device 100 can be made more compact, which is conducive to the miniaturization of the electronic device 100.

[0059] Wherein, since the electronic device 100 in this embodiment includes the control device 30, it can be understood that the electronic device 100 at least includes the same beneficial effects as the control device 30. Therefore, for the beneficial effects of the electronic device 100, please refer to the beneficial effects of the control device 30 introduced below.

[0060] Please refer to Figure 2 and Figure 3 , the control device 30 of the embodiment of the present application includes a housing 31 and a control module 33. The housing 31 is provided with an accommodation cavity 311, and a coolant is accommodated in the accommodation cavity 311. The control module 33 is disposed in the accommodation cavity 311, and the coolant is used to cool the control module 33.

[0061] Further, in some embodiments, the control module 33 includes a power conversion system (PCS) 331 and a battery management system (BMS) 333. The power conversion system 331 is disposed in the accommodation cavity 311. The battery management system 333 is disposed in the accommodation cavity 311, and the coolant is used to cool the power conversion system 331 and the battery management system 333.

[0062] Wherein, the housing 31 refers to an element that can isolate the control module 33 from the external environment. Among them, the housing 31 can be made of one or more of materials such as copper, iron, aluminum, stainless steel, aluminum alloy, or plastic. Exemplarily, the housing 31 can be made of plastic, so as to improve the safety performance of the control device 30.

[0063] The PCS 331 is a device that can control the charging and discharging processes of the battery cluster 20, and the PCS 331 can perform AC-DC conversion. Exemplarily, the PCS 331 can either invert the direct current of the battery cluster 20 into alternating current and transmit it to the power grid or supply it to an AC load, or rectify the alternating current of the power grid into direct current to charge the battery cluster 20.

[0064] BMS333 is a device that monitors the operating parameters (such as current, voltage, and temperature, etc.) of the battery cluster 20 and provides functions such as data acquisition, data processing, communication, and control. In the embodiments of the present application, both the PCS331 and the BMS333 are disposed in the accommodation cavity 311 of the housing 31. Thus, on the one hand, it is convenient for the wiring connection between the PCS331 and the BMS333, reduces the complexity of the wiring of the control device 30, reduces the failure risk of the control device 30, and ensures the stability and reliability of the operation of the control device 30; on the other hand, it can make the layout of the control device 30 more compact, which is beneficial to the miniaturization of the control device 30.

[0065] In some embodiments of the present application, the coolant can perform immersion cooling on the control module 33. In this way, the contact area between the cooling medium and the PCS331 and the BMS333 can be increased, and the heat dissipation effect of the coolant on the control module 33 can be improved. Among them, the coolant needs to have the following characteristics: good electrical insulation, non-flammable and having a high flash point, an appropriate operating temperature range, a long service life, good material compatibility, low weight, low viscosity, low corrosiveness, and sustainability. The coolant includes but is not limited to hydrofluoroethers, synthetic oils (such as silicone oils), water (electrical isolation needs to be achieved by using silicone sealants or boron nitride for sealing), or fluorinated liquids, etc. It can be understood that the coolant can also cool and dissipate heat from other devices in the control device 30 that can generate heat during operation.

[0066] In the control device 30 according to the embodiments of the present application, the housing 31 is provided with an accommodation cavity 311, the accommodation cavity 311 contains the coolant, the control module 33 is disposed in the accommodation cavity 311, and the coolant can cool the control module 33, thereby preventing the heat generated during the operation of the control module 33 from accumulating and causing the control module 33 to be overheated and damaged, and further ensuring the normal operation of the control device 30 and the electronic device 100, and improving the safety performance of the electronic device 100.

[0067] In some embodiments, the coolant fills the accommodation cavity 311. Specifically, the coolant can fill every cavity inside the housing 31. In this way, the coolant can completely immerse the PCS331 and the BMS333, thereby further improving the cooling and heat dissipation effect of the coolant on the PCS331 and the BMS333, and ensuring the stability and reliability of the operation of the control module 33.

[0068] In some other embodiments, the coolant does not fill the accommodation cavity 311. Specifically, the coolant does not completely fill every cavity inside the housing 31. In this case, the coolant can semi-immerse the PCS 331 and the BMS 333, that is, the coolant can immerse the key heat-generating parts of the PCS 331 and the BMS 333, so as to realize the cooling and heat dissipation of the PCS 331 and the BMS 333. In the embodiments of the present application, only the case where the coolant does not fill the accommodation cavity 311 is taken as an example for illustration.

[0069] Please refer to Figure 2 、 Figure 4 and Figure 5 , in some embodiments, the housing 31 is provided with an inlet 313 and an outlet 315 communicating with the accommodation cavity 311. The control device 30 further includes a pipeline assembly 35. The pipeline assembly 35 includes a circulation pipeline 351. The circulation pipeline 351 is arranged in the accommodation cavity 311. One end of the circulation pipeline 351 communicates with the inlet 313, and the other end communicates with the outlet 315. The inlet 313 is used for the cooling medium to flow into the circulation pipeline 351, and the outlet 315 is used for the cooling medium to flow out of the circulation pipeline 351. The cooling medium is used to cool the coolant.

[0070] Specifically, in some embodiments, when the cooling medium flows in the circulation pipeline 351, the cooling medium can exchange heat with the coolant in the accommodation cavity 311 in a non-contact manner, that is, the cooling medium can exchange heat with the coolant through the circulation pipeline 351. In this case, the heat generated during the operation of the PCS 331 and the BMS 333 absorbed by the coolant can be transferred to the cooling medium through the circulation pipeline 351. In this way, the cooling medium can realize the heat dissipation of the coolant, so as to realize the cooling and heat dissipation of the PCS 331 and the BMS 333 by the cooling medium.

[0071] It can be understood that in this embodiment, the cooling medium includes but is not limited to coolant, cooling gas or a mixture of coolant and cooling gas. The coolant includes but is not limited to ethylene glycol, propylene glycol, fluorinated liquid or synthetic oil, etc.; the cooling gas includes but is not limited to ammonia or hydrogen, etc.

[0072] It can be understood that when the coolant cools and dissipates heat from the PCS 331 and the BMS 333, the temperature rise of the coolant closer to the PCS 331 and the BMS 333 may be greater than that of the coolant farther from the PCS 331 and the BMS 333. Therefore, in some embodiments of the present application, the circulation pipeline 351 is arranged around the PCS 331, the circulation pipeline 351 is arranged around the BMS 333, or the circulation pipeline 351 is arranged around the PCS 331 and the BMS 333, so as to improve the heat exchange efficiency of the cooling medium with the coolant, and further improve the cooling efficiency of the PCS 331 and the BMS 333.

[0073] Please combineFigure 5 , in some embodiments, the pipeline assembly 35 further includes a heat conducting member 352. The heat conducting member 352 is sleeved on the outer peripheral wall of the circulation pipeline 351, and the heat conducting member 352 is used to increase the contact area between the outer peripheral wall of the circulation pipeline 351 and the coolant. It should be noted that, in some embodiments, the heat conducting member 352 can be made of one or more of materials with good heat conduction performance such as gold, silver, copper, aluminum nitride, and silicon carbide.

[0074] Specifically, the setting of the heat conducting member 352 can increase the contact area between the outer peripheral wall of the circulation pipeline 351 and the coolant. In this way, when the cooling medium flows in the circulation pipeline 351, the heat exchange efficiency between the cooling medium and the coolant is higher, so that the cooling effect and cooling efficiency of the cooling medium on the control module 33 can be improved.

[0075] In some embodiments, the heat conducting member 352 and the circulation pipeline 351 can be combined together by a detachable connection method. The detachable connection method includes but is not limited to threaded connection or snap connection, etc. In other embodiments, the heat conducting member 352 and the circulation pipeline 351 can be combined together by a non-detachable connection method. The non-detachable connection method includes but is not limited to welding or bonding, etc.

[0076] Please refer to Figures 2 to 4 , in some embodiments, the control device 30 further includes a partition member 35. The partition member 35 is connected to the inner wall of the housing 31 and divides the accommodation cavity 311 into a direct current area 3111 and an alternating current area 3113. The battery management system 333 is accommodated in the direct current area 3111, and the energy storage converter 331 is accommodated in the alternating current area 3113. The partition member 35 is provided with a through hole 351, and the through hole 351 is used to communicate the direct current area 3111 and the alternating current area 3113.

[0077] Among them, the setting of the partition member 35 can prevent interference between alternating current and direct current. Thus, on the one hand, the safety performance of the control device 30 can be improved; on the other hand, the stability and reliability of the operation of the control device 30 can be ensured. In some embodiments, the through hole 351 penetrates through the partition member 35 to communicate the direct current area 3111 and the alternating current area 3113. Thus, on the one hand, it is convenient for the coolant to flow between the direct current area 3111 and the alternating current area 3113; on the other hand, the circulation pipeline can pass through the through hole 351 and be located in the direct current area 3111 and the alternating current area 3113. So that when the cooling medium flows in the circulation pipeline, the cooling medium can cool and dissipate heat from the PCS 331 and the BMS 333.

[0078] In some embodiments, the separator 35 and the housing 31 are of an integral structure, that is, the separator 35 and the housing 31 are a single integral structure, thereby enhancing the bonding strength between the separator 35 and the housing 31 and reducing the possibility of the separator 35 detaching from the housing 31. In other embodiments, the separator 35 and the housing 31 are of a split structure, that is, the separator 35 and the housing 31 are two different structures. In some examples, the separator 35 and the housing 31 can be joined together by a non-detachable connection method, and the non-detachable connection methods include but are not limited to bonding or welding, etc. In other examples, the separator 35 and the housing 31 can be joined together by a detachable connection method, and the detachable connection methods include but are not limited to bolt connection or snap connection, etc.

[0079] Please refer to Figure 2 and Figure 4 , in certain embodiments, the circuit assembly 60 and the direct current area 3111 are located on the same side of the cabinet 10.

[0080] Specifically, in certain embodiments, in the direction from the alternating current area 3113 to the direct current area 3111, the housing 31 includes a first side and a second side facing away from each other, and the direct current area 3111 is closer to the first side of the housing 31 than the alternating current area 3113. In the direction from the alternating current area 3113 to the direct current area 3111, the battery cluster 20 includes a first side and a second side facing away from each other, and the circuit assembly 60 is disposed on the first side of the battery cluster 20, wherein the first side of the battery cluster 20 and the first side of the housing 31 are on the same side. Thus, the circuit assembly 60 and the direct current area 3111 are located on the same side of the cabinet 10, which facilitates the electrical connection between the battery cluster 20 and the BMS 333 through the circuit assembly 60. Compared with the case where the circuit assembly 60 and the direct current area 3111 are located on different sides of the cabinet 10, the length of the circuit assembly 60 is shorter, thereby reducing the loss of electrical energy during transmission and improving the overall efficiency.

[0081] Please refer to Figure 2 and Figure 3 , in certain embodiments, the electronic device 100 includes a cooling module 40, and the cooling module 40 is in communication with the housing 31 through a pipeline assembly 35 to form a first circulation path for the cooling medium to flow.

[0082] Among them, please combine Figure 5 and Figure 6, the cooling module 40 is a device that cools the control device 30 using a cooling medium. The cooling module 40 is connected to the housing 31 through a pipeline assembly 35 to form a first circulation path for the cooling medium to flow. The cooling medium circulates in the first circulation path to cool the control device 30. Exemplarily, the cooling medium at a lower temperature in the cooling module 40 enters the interior of the control device 30 through the pipeline assembly 35, and its temperature becomes higher after absorbing the heat generated during the operation of the control device 30. In this way, the temperature of the control device 30 can be ensured within the required range, while the cooling medium at a higher temperature flows out of the control device 30 through the pipeline assembly 35 and returns to the cooling module 40. After being processed by the cooling module 40, it is again transformed into a cooling medium at a lower temperature, and the cooling medium at a lower temperature can enter the control device 30 through the pipeline assembly 35 again to form a circulating heat dissipation for the control device 30.

[0083] It should be noted that in some embodiments, the flow rate of the cooling medium flowing in the pipeline assembly 35 is adjustable. Exemplarily, a speed regulation unit can be provided on the pipeline assembly 35, and the speed regulation unit can accelerate the flow rate of the cooling medium flowing in the pipeline assembly 35, thereby improving the cooling and heat dissipation efficiency of the cooling medium for the control device 30.

[0084] Please refer to Figure 2 , Figure 3 and Figure 5 , in some embodiments, the housing 31 is provided with an inlet 313 and an outlet 315 communicating with the accommodation cavity 311; the pipeline assembly 35 includes a circulation pipeline 351, and the circulation pipeline 351 is arranged in the accommodation cavity 311. The pipeline assembly 35 includes a first main pipeline 353, a second main pipeline 354, a first branch pipeline 355 and a second branch pipeline 356. The first main pipeline 353 is connected to the cooling module 40. The second main pipeline 354 is connected to the cooling module 40. One end of the first branch pipeline 355 is connected to the first main pipeline 353, and the other end is connected to the circulation pipeline 351 through the inlet 313. One end of the second branch pipeline 356 is connected to the second main pipeline 354, and the other end is connected to the circulation pipeline 351 through the outlet 315.

[0085] Specifically, in some embodiments, when the cooling medium in the first main pipeline 353 flows into the first branch pipeline 355, the cooling medium in the first branch pipeline 355 can flow into the circulation pipeline 351 through the inlet 313 and flow in the circulation pipeline 351 to achieve non-contact heat exchange with the coolant; the cooling medium in the circulation pipeline 351 can flow into the second branch pipeline 356 through the outlet 315, and the cooling medium in the second branch pipeline 356 can flow into the second main pipeline 354.

[0086] Further, in some embodiments, the first main pipeline 353 and the second main pipeline 354 can be connected through the cooling module 40, and the cooling module 40 can cool the cooling medium.

[0087] Specifically, in some embodiments, the pipeline assembly 35 further includes a first main pipeline 357 and a second main pipeline 358. One end of the first main pipeline 357 is connected to the cooling module 40, and the other end is connected to the first main pipeline 353 of the pipeline assembly 35. The first main pipeline 357 is used for the cooling medium in the cooling module 40 to flow into the first main pipeline 353. One end of the second main pipeline 358 is connected to the cooling module 40, and the other end is connected to the second main pipeline 354 of the pipeline assembly 35. The second main pipeline 358 is used for the cooling medium in the second main pipeline 354 to flow into the cooling module 40.

[0088] Among them, the cooling medium at a lower temperature in the cooling module 40 flows into the first main pipeline 353 through the first main pipeline 357, and sequentially flows through the first branch pipeline 355, the circulation pipeline 351, the second branch pipeline 356 and the second main pipeline 354 and then flows back into the cooling module 40. Among them, the temperature of the cooling medium flowing back into the cooling module 40 becomes higher, and the cooling module 40 can cool the cooling medium at a higher temperature to make it a cooling medium at a lower temperature. The cooling medium at a lower temperature can flow into the first main pipeline 353 through the first main pipeline 357 again to form a circulating heat dissipation.

[0089] More specifically, in some embodiments, the cooling module 40 includes a cooling member 43, and the cooling member 43 is connected to the pipeline assembly 35. The cooling member 43 is used for cooling the cooling medium. It should be noted that, in some embodiments, the cooling member 43 includes a chiller or a liquid-cooled air conditioner, etc.

[0090] Among them, one end of the first main pipeline 357 is connected to the cooling member 43, and the other end is connected to the first main pipeline 353 of the pipeline assembly 35. One end of the second main pipeline 358 is connected to the cooling member 43, and the other end is connected to the second main pipeline 354 of the pipeline assembly 35. The cooling medium at a lower temperature in the cooling member 43 flows into the first main pipeline 353 through the first main pipeline 357, and sequentially flows through the first branch pipeline 355, the circulation pipeline 351, the second branch pipeline 356 and the second main pipeline 354 and then flows back into the cooling member 43. Among them, the temperature of the cooling medium flowing back into the cooling member 43 becomes higher, and the cooling member 43 can cool the cooling medium at a higher temperature to make it a cooling medium at a lower temperature. The cooling medium at a lower temperature can flow into the first main pipeline 353 through the first main pipeline 357 again to form a circulating heat dissipation.

[0091] In some embodiments, the cooling member 43 is disposed within the accommodation chamber 11. This can facilitate the connection between the cooling member 43 and the pipeline assembly 35, shorten the flow path of the cooling medium, and thus improve the cooling efficiency of the cooling medium for the control module 33. In other embodiments, the cooling member 43 is disposed outside the accommodation chamber 11. On the one hand, this can facilitate the loading and unloading of the cooling member 43 and improve the assembly efficiency of the energy storage device; on the other hand, it can facilitate the repair or replacement when the cooling member 43 is damaged, ensuring the normal operation of the energy storage device.

[0092] It should be noted that, in certain embodiments, the pipeline assembly 35 (including the first main pipeline 353, the first branch pipeline 355, the circulation pipeline 351, the second main pipeline 354, the second branch pipeline 356, the first main pipeline 357, the second main pipeline 358, etc.) can be made of insulating materials, thereby improving the safety performance of the energy storage device. Among them, the insulating materials include but are not limited to plastics, rubbers, glass, mica, etc.

[0093] Please refer to Figures 2 to 4 , in certain embodiments, both the inlet 313 of the housing 31 and the outlet 315 of the housing 31 communicate with the DC area 3111. This can make the layout of the pipeline assembly 35 and the circuit assembly 60 in the accommodation chamber 11 more compact, thereby reducing the space occupied by the pipeline assembly 35 and the circuit assembly 60, and further facilitating the miniaturization of the electronic device 100.

[0094] In addition, compared with the case where one of the inlet 313 and the outlet 315 communicates with the DC area 3111 and the other communicates with the AC area 3113, the fact that both the inlet 313 and the outlet 315 communicate with the DC area 3111 can, on the one hand, reduce the space occupied by the pipeline assembly 35, facilitating the miniaturization of the electronic device 100; on the other hand, it can reduce the possibility of interference between the pipeline assembly 35 and other structures of the electronic device 100 (such as the cabinet 10, etc.), thus ensuring the normal assembly of the pipeline assembly 35.

[0095] Please refer to Figure 2 , Figure 3 and Figure 6 , in certain embodiments, the cooling module 40 includes an aerodynamic device 41, the aerodynamic device 41 is disposed on the housing 31, and the aerodynamic device 41 is used to accelerate the flow of the coolant in the accommodation cavity 311.

[0096] Specifically, in some embodiments, the aerodynamic device 41 includes a suction member and an accelerator. The suction member is disposed in the housing 31 and is used to suck the gas in the accommodation chamber 311. The accelerator is disposed in the housing 31 and is used to accelerate the gas sucked by the suction member and introduce the accelerated gas into the accommodation chamber 311 to accelerate the flow of the coolant. Thus, the coolant can form a turbulent flow, so that the coolant can be in full contact with the circulation pipeline 351, that is, to ensure full heat exchange between the cooling medium and the coolant, improve the heat exchange efficiency of the cooling medium to the coolant, and further improve the cooling effect and cooling efficiency of the cooling medium on the control device 30.

[0097] In some embodiments, a support column 317 is provided on the housing 31. The support column 317 protrudes and extends from the inner wall of the housing 31 toward the center of the accommodation chamber 311, and the support column 317 is used to support the control module 33 so that the control module 33 is spaced from the inner wall of the housing 31.

[0098] Specifically, in some embodiments, when the PCS 331 and the BMS 333 are disposed in the accommodation chamber 311 and carried on the support column 317, there is a certain gap between the PCS 331 and the BMS 333 and the bottom of the inner wall of the housing 31. Thus, the coolant can contact the bottoms of the PCS 331 and the BMS 333 (the lowermost ends of the PCS 331 and the BMS 333 in the figure) through this gap. Compared with the case where there is no gap between the PCS 331 and the BMS 333 and the bottom of the inner wall of the housing 31, the contact area between the coolant and the PCS 331 and the BMS 333 is larger, so that the cooling and heat dissipation effect of the coolant on the PCS 331 and the BMS 333 can be further improved, ensuring the normal operation of the control device 30.

[0099] In addition, as can be seen from the above, the accelerator can accelerate the gas sucked by the suction member and introduce the accelerated gas into the accommodation chamber 311 to accelerate the flow of the coolant. If the accelerator is disposed at the bottom of the housing 31 and there is no gap between the PCS 331 and the BMS 333 and the bottom of the inner wall of the housing 31, it is difficult for the accelerator to introduce the accelerated gas into the accommodation chamber 311, which will cause the coolant to be unable to flow at an accelerated rate. Thus, the support column 317 is used to support the PCS 331 and the BMS 333 so that the PCS 331 and the BMS 333 are both spaced from the inner wall of the housing 31, and can also enable the accelerator to introduce the accelerated gas into the accommodation chamber 311 to accelerate the flow of the coolant, thereby improving the heat exchange efficiency of the cooling medium to the coolant, and further improving the cooling effect and cooling efficiency of the cooling medium on the control device 30.

[0100] In the related art, heat is generated during the operation of the battery pack. If the heat cannot be dissipated in time, the heat will accumulate, resulting in overheating and damage of the battery pack, thus affecting the normal operation of the electronic device and being unfavorable to the use safety of the electronic device. Please refer to Figure 2 , in some embodiments, the cooling module 40 is also connected to the battery pack 21 through a pipe assembly 70 to form a second circulation path for the cooling medium to flow, and the cooling medium is also used to cool the battery pack 21.

[0101] Specifically, when the cooling medium flows into the battery pack 21 through the second circulation path, the cooling medium can cool and dissipate heat from the battery cells 213, thereby preventing the heat generated during the operation of the battery cells 213 from accumulating and causing overheating damage, and further ensuring the normal operation of the battery pack 21 and extending the service life of the battery pack 21. It can be understood that the cooling medium can also cool and dissipate heat from other devices in the battery pack 21 that can generate heat during operation.

[0102] Among them, the cooling medium can enter the box body 211 to perform immersion cooling on the battery cells 213, so as to increase the contact area between the cooling medium and the battery cells 213 and improve the heat dissipation effect of the cooling medium on the battery pack 21. When the cooling medium performs immersion cooling on the battery cells 213, the cooling medium needs to have the following characteristics: good electrical insulation, non-flammable and having a high flash point, appropriate working temperature range, long service life, good material compatibility, low weight, low viscosity, low corrosiveness, and sustainability. The cooling medium can be a coolant, a cooling gas, or a mixture of a coolant and a cooling gas. For example, the cooling medium includes but is not limited to hydrofluoroethers, synthetic oils (such as silicone oils), water (electrical isolation needs to be achieved by using silicone sealants or boron nitride for sealing), fluorinated liquids, helium, nitrogen, fluorocarbons, or hydrocarbons, etc.

[0103] Please continue to refer to Figure 2 , in some embodiments, the box body 211 is provided with a first interface 2111 and a second interface 2113 that communicate with the inside of the box body 211. The pipe assembly 70 includes a first main pipe 71, a second main pipe 73, a first branch pipe 75, and a second branch pipe 77. The first main pipe 71 is connected to the cooling module 40. The second main pipe 73 is connected to the cooling module 40. The first branch pipe 75 connects the first main pipe 71 and the first interface 2111. The second branch pipe 77 connects the second main pipe 73 and the second interface 2113.

[0104] Specifically, in some embodiments, when the cooling medium in the first main pipe 71 flows into the first branch pipe 75, the cooling medium in the first branch pipe 75 can flow into the box body 211 through the first interface 2111 and perform immersion cooling on the battery cell 213; the cooling medium in the box body 211 can flow into the second branch pipe 77 through the second interface 2113, and the cooling medium in the second branch pipe 77 can flow into the second main pipe 73.

[0105] It should be noted that, in some embodiments, the pipe assembly 70 (including the first main pipe 71, the second main pipe 73, the first branch pipe 75, the second branch pipe 77, etc.) can be made of insulating materials, so as to improve the safety performance of the electronic device 100. Among them, the insulating materials include but are not limited to plastics, rubbers, glass, mica, etc.

[0106] Please refer to Figure 2 and Figure 5 , in some embodiments, the cooling member 43 includes one. Specifically, when the cooling member 43 includes one, the first circulation path and the second circulation path share one cooling member 43. In this case, the first main pipe 71 of the pipe assembly 70 and the first main pipeline 353 of the pipeline assembly 35 are of the same structure, and the second main pipe 73 of the pipe assembly 70 and the second main pipeline 354 of the pipeline assembly 35 are of the same structure. Thus, when the cooling medium in the cooling member 43 flows into the first main pipe 71, the cooling medium in the first main pipeline 353 can flow into the box body 211 through the first branch pipe 75 and flow back to the cooling member 43 through the second branch pipe 77 and the second main pipe 73 to achieve cooling and heat dissipation of the battery pack 21; when the cooling medium in the cooling member 43 flows into the first main pipeline 353, the cooling medium in the first main pipeline 353 can flow into the circulation pipeline 351 through the first branch pipeline 355 and flow back to the cooling member 43 through the second branch pipeline 356 and the second main pipeline 354 to achieve cooling and heat dissipation of the control device 30.

[0107] In some other embodiments, the cooling member 43 includes two. Specifically, when the cooling member 43 includes two, the first circulation path and the second circulation path respectively correspond to the two cooling members 43. For example, the two cooling members 43 are a first cooling member and a second cooling member. Among them, the cooling medium in the first cooling member can flow into the first main pipe 71 of the pipe assembly 70. The cooling medium in the first main pipe 71 of the pipe assembly 70 can flow into the box body 211 through the first branch pipe 75, and flow back to the first cooling member through the second branch pipe 77 and the second main pipe 73 of the pipe assembly 70 to achieve the cooling and heat dissipation of the battery pack 21. The cooling medium in the second cooling member can flow into the first main pipeline 353 of the pipeline assembly 35. The cooling medium in the first main pipeline 353 of the pipeline assembly 35 can flow into the box body 211 through the first branch pipeline 355, and flow back to the first cooling member through the second branch pipeline 356 and the second main pipeline 354 of the pipeline assembly 35 to achieve the cooling and heat dissipation of the control device 30.

[0108] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification. At the same time, other embodiments can be derived from the above-described embodiments, so that structural and logical substitutions and changes can be made without departing from the scope of the present disclosure.

[0109] The above-described embodiments only represent several implementation manners of the present application, and the description thereof is relatively specific and detailed, but it should not be understood as a limitation to the scope of the patent. It should be noted that for those of ordinary skill in the art, several deformations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
