Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to water-cooled structures, batteries, and electrical devices. Background Technology

[0002] The battery box is equipped with a water-cooled plate for cooling. The water-cooled plate has an inlet and an outlet, which are connected to water-cooling pipes. This allows the cooling fluid to circulate within the water-cooled plate and pipes to remove heat from the battery box.

[0003] Water inlets and outlets are typically equipped with water nozzles, which connect to the water cooling pipes. These nozzles are prone to corrosion and may leak over time. If a water nozzle corrodes and leaks, the entire battery box needs to be replaced, which is costly. Utility Model Content

[0004] In view of the above problems, this application provides a water-cooling structure, battery and power supply device, which can alleviate the problem of water taps being corroded and leaking, making replacement inconvenient.

[0005] In a first aspect, this application provides a water-cooling structure, which includes:

[0007] The water tap assembly is detachably mounted on the water cooling body and maintains electrical connection with the water cooling body; the water tap assembly is provided with a through water passage, one end of which is connected to the water inlet, and the other end is used to connect to the external pipeline.

[0008] The water-cooling structure provided in this application includes a water-cooling body and a water nozzle assembly. The internal flow channels of the water-cooling body allow fluid to flow and regulate the temperature of the battery cells. The water-cooling body is equipped with a water nozzle assembly, which connects the water-cooling body and external pipelines through its water passages, enabling fluid circulation between the water-cooling body, the water nozzle assembly, and the external pipelines. By maintaining electrical contact between the water nozzle assembly and the water-cooling body, electrolytic corrosion occurs on the water nozzle assembly, especially at the connection point between the water nozzle assembly and the external pipelines. Furthermore, by detachably mounting the water nozzle assembly to the water-cooling body, it can be quickly replaced in case of corrosion leading to leakage or other damage, thus reducing battery costs.

[0009] In some other embodiments, the water-cooling structure further includes:

[0010] The counter component is located on the water cooling body, and the water nozzle assembly is detachably mounted on the counter component; the counter component is provided with a connection channel that connects the water inlet and the water passage; wherein, the counter component is electrically connected to the water nozzle assembly.

[0011] The water-cooling structure provided in this application embodiment facilitates the assembly of the water nozzle assembly by providing a counterslip. By electrically connecting the counterslip to the water nozzle assembly, the water nozzle assembly and the water-cooling body maintain essentially the same potential, thus ensuring that electrolytic corrosion still occurs at the water nozzle assembly, providing good protection for both the counterslip and the water-cooling body.

[0012] In some other embodiments, the faucet assembly includes:

[0014] A water-passing component with a water-passing channel, one end of which passes through the connector and is inserted into the connecting channel.

[0015] The water-cooling structure provided in this application embodiment uses a water-passing component with a water-passing channel inserted into a connecting channel to connect the water-passing channel and the connecting channel, thereby achieving fluid channel connectivity. Simultaneously, the connecting channel also serves to position the water-passing component, facilitating connection between the component and the matching component. Furthermore, the connecting component allows for detachable connection with the matching component, enabling the water-passing component to be securely engaged with the connecting channel or to release the water-passing component from fixation.

[0016] In some other embodiments, the water passage element and the connector are constructed as a single unit.

[0017] The water-cooled structure provided in this application embodiment can be integrally formed by casting, resulting in good structural strength and faster processing.

[0018] In some other embodiments, the water-cooling structure further includes:

[0019] The locking assembly is configured to lock and secure the connector and the counter.

[0020] The water-cooling structure provided in this application embodiment improves the connectivity stability between the water-passing channel inside the water-passing component and the connecting channel inside the hand component through the above-mentioned configuration.

[0024] In some other embodiments, the locking assembly is electrically connected to the connector; and / or the locking assembly is electrically connected to the counter.

[0025] The water-cooling structure provided in this application embodiment, through the above-mentioned configuration, can form good conductivity between the connector and the counterpart, reduce electrolytic corrosion in the contact area between the locking component and the counterpart, and between the locking component and the connector, so that the electrolytic corrosion occurs at the end of the water-passing component away from the counterpart, which is more conducive to forming good protection for the counterpart.

[0026] In some other embodiments, the connector is provided with a through first connecting hole; the surface of the opponent facing the connector is provided with a second connecting hole, and the second connecting hole is spaced apart from the surface of the opponent facing away from the connector; the fastener passes through the first connecting hole and is connected to the second connecting hole.

[0027] The water-cooling structure provided in this application embodiment, through the above-mentioned arrangement, makes the second connecting hole a blind hole. When the fastener is inserted into the second connecting hole, due to the barrier of the hand component, the fastener can be separated from the flow channel in the water-cooling body, which is more conducive to maintaining isolation from the fluid in the flow channel.

[0028] In some other embodiments, a connecting channel is provided through the opponent in the first direction; the opponent has a first surface and a second surface opposite to each other in the first direction, the first surface is connected to the water-cooling body, the second surface is attached to the connector, and is locked by a locking component.

[0029] The water-cooling structure provided in this application embodiment is assembled by connecting the connecting channel to the water inlet, connecting the first surface of the counter part to the water-cooling body, attaching the connector to the second surface of the counter part, connecting the water passage to the connecting channel, and then locking the connector and the counter part with a locking assembly.

[0030] In some other embodiments, the water passage extends along a first direction, and the water passage protrudes along the first direction from both sides of the connector.

[0031] The water-cooling structure provided in this application embodiment, through the above configuration, allows the end of the water-passing component protruding towards the opposing component to be inserted into the connecting channel, while the end protruding away from the opposing component forms the connecting end, which is used to connect with external pipelines.

[0032] In some other embodiments, a seal is sandwiched between the water-passing component and the connecting channel.

[0033] The water-cooling structure provided in this application improves the sealing performance between the water-passing component and the inner wall of the connecting channel by setting a sealing element.

[0034] In some other embodiments, the hand component is fixedly connected to the water-cooling body.

[0035] The water-cooling structure provided in this application embodiment is generally not required to replace hand components because they are not easily corroded by electrolysis. The fixed connection method is more conducive to improving the connection strength with the water-cooling body.

[0036] In some other embodiments, the handpiece is welded to the water-cooled body.

[0037] The water-cooled structure provided in this application embodiment has a welding method with high connection strength and good sealing performance, which is more conducive to improving the connection sealing performance of the connection channel and the internal flow channel of the water-cooled body and reducing leakage.

[0038] In some other embodiments, the hand component is provided with a weight-reducing groove, which is offset from the connecting channel.

[0039] The water-cooling structure provided in this application embodiment, by setting a weight-reducing groove, helps to reduce the weight of the water-cooling structure and save materials.

[0064] Currently, judging from market trends, battery applications are becoming increasingly widespread. Batteries are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but also extensively used in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in other fields. With the continuous expansion of battery applications, market demand is also constantly increasing.

[0065] To improve the reliability and stability of battery operation, thermal management components are typically installed inside the casing. In some cases, the thermal management component is located at the bottom of the casing and fixedly mounted to the side wall. In other cases, the thermal management component is located between adjacent battery cells, in close contact with the large surface area of ​​the battery cells. In still other cases, multiple battery cells are arranged in multiple rows, with the thermal management component located on at least one side of each row of battery cells. The battery cells are generally connected to the thermal management component using thermally conductive adhesive to allow heat exchange between the battery cells and the thermal management component, so that the temperature of the battery cells in contact with the thermal management component changes accordingly when the temperature of the thermal management component changes. Generally, the thermal management component itself and the pipes and connectors used to form connections with the thermal management component can be collectively referred to as a water-cooling structure.

[0066] Typically, thermal management components contain a fluid that can regulate the temperature of multiple battery cells. This fluid can be a liquid or a gas, and temperature regulation refers to heating or cooling the multiple battery cells. When cooling or dissipating heat from the battery cells, this thermal management component can be called a cooling component, cooling system, or cooling plate, etc., and the fluid it contains can be called a cooling medium or cooling fluid, more specifically, a coolant or cooling gas. Alternatively, the thermal management component can also be used to heat multiple battery cells to raise their temperature. The fluid can also be called a heat exchange medium; optionally, the fluid can be circulating to achieve better temperature regulation. Optionally, the fluid can be water, a mixture of water and ethylene glycol, or air, etc.

[0067] The inventors of this application noted that the cooling fluid is generally contained within a water-cooled plate, which has an inlet and an outlet. The inlet and outlet are connected to water-cooling pipes, allowing the fluid to circulate within the water-cooled plate and pipes to remove heat from the battery pack. Water nozzles are typically installed at the inlet and outlet, connecting to the water-cooling pipes. In high-voltage cascaded energy storage systems, voltage differences exist between battery clusters, causing electrolytic corrosion of the water nozzles located between two clusters. If a water nozzle corrodes and leaks, the entire battery pack needs to be replaced, resulting in high costs.

[0068] Based on the above considerations, in order to solve the problem of water taps being corroded and leaking, making replacement inconvenient, the inventors, after in-depth research, designed a water-cooling structure. By detachably assembling the water tap assembly onto the water-cooling body and maintaining electrical connection with the water-cooling body, electrolytic corrosion caused by voltage differences between battery clusters occurs at the water tap assembly. This allows for flexible replacement of corroded and leaking water tap assemblies, alleviating the problem of traditional water taps being fixedly connected to the water-cooling body and unable to be replaced.

[0069] This application also provides a battery that employs the above-described water-cooling structure.

[0070] This application also provides an electrical device that provides electrical energy through the aforementioned battery. The electrical device can be, but is not limited to, mobile phones, tablets, laptops, electric toys, power tools, electric vehicles, electric cars, ships, spacecraft, etc. Electric toys can include stationary or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, etc. Spacecraft can include airplanes, rockets, space shuttles, and spacecraft, etc.

[0071] In some embodiments, the electrical device can be a vehicle. The vehicle can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle; a new energy vehicle can be a pure electric vehicle, a hybrid electric vehicle, or a range-extended electric vehicle, etc. A battery device is installed inside the vehicle, and the battery device can be located at the bottom, front, or rear of the vehicle. The battery device can be used to power the vehicle; for example, the battery device can serve as the vehicle's operating power source. The vehicle may also include a controller and a motor, and the controller can be used to control the battery device to power the motor. For example, the battery device can be used to meet the vehicle's power needs during starting, navigation, and driving.

[0072] For ease of explanation, the following embodiments will be described using a vehicle 1000 as an example of an electrical device according to an embodiment of this application.

[0073] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of a vehicle 1000 provided in some embodiments of this application. Taking the vehicle 1000 as an example, the vehicle 1000 can be a gasoline vehicle, a natural gas vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc. A battery 100 is installed inside the vehicle 1000, and the battery 100 can be located at the bottom, front, or rear of the vehicle 1000. The battery 100 can be used to power the vehicle 1000; for example, the battery 100 can serve as the operating power source for the vehicle 1000. The vehicle 1000 may also include a controller 200 and a motor 300. The controller 200 is used to control the battery 100 to supply power to the motor 300, for example, to meet the power needs of the vehicle 1000 during starting, navigation, and driving.

[0074] In some embodiments, the battery 100 can not only serve as the operating power source for the vehicle 1000, but also as the driving power source for the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0075] Please refer to Figure 2 , Figure 2 This is a schematic diagram of the structure of a battery 100 provided in some embodiments of this application. In some embodiments, the battery 100 includes a housing 10 and a battery cell 20, with the battery cell 20 housed within the housing 10.

[0076] The housing 10 provides a space for housing the battery cell 20, and the housing 10 can adopt various structures. In some embodiments, the housing 10 may include a first part 11 and a second part 12, which overlap each other, and together define a space for housing the battery cell 20. The second part 12 may be a hollow structure with one end open, and the first part 11 may be a plate-like structure, with the first part 11 covering the open side of the second part 12 so that the first part 11 and the second part 12 together define the space; alternatively, the first part 11 and the second part 12 may both be hollow structures with one side open, with the open side of the first part 11 covering the open side of the second part 12. Of course, the housing 10 formed by the first part 11 and the second part 12 can be of various shapes, such as a cylinder, a cuboid, etc.

[0077] In battery 100, there can be multiple battery cells 20, which can be connected in series, parallel, or a combination thereof. A combination thereof means that multiple battery cells 20 are connected in both series and parallel. Multiple battery cells 20 can be directly connected in series, parallel, or a combination thereof, and then the entire assembly of multiple battery cells 20 is housed within housing 10. Battery 100 may also include other structures; for example, battery 100 may also include a busbar component for realizing electrical connection between multiple battery cells 20.

[0078] Please see Figure 3 , Figure 3 This is a schematic diagram of the structure of a battery cell 20 provided in some embodiments of this application. The battery cell 20 includes an end cap 21, a casing 22, a cell 23, and other functional components.

[0079] End cap 21 refers to a component that covers the opening of housing 22 to isolate the internal environment of battery cell 20 from the external environment. The shape of end cap 21 can be adapted to the shape of housing 22 to fit it. Optionally, end cap 21 can be made of a material with certain hardness and strength (such as aluminum alloy), so that end cap 21 is not easily deformed under pressure or impact, allowing battery cell 20 to have higher structural strength. Functional components such as electrode terminals 21a can be provided on end cap 21. Electrode terminals 21a can be used for electrical connection with battery cell 23 to output or input electrical energy to battery cell 20. In some embodiments, end cap 21 can also be provided with a pressure relief mechanism for releasing internal pressure when the internal pressure or temperature of battery cell 20 reaches a threshold. The material of end cap 21 can also be various, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., and this application embodiment does not impose any special limitations on this. In some embodiments, an insulating element may also be provided on the inner side of the end cap 21 to reduce the risk of short circuit. For example, the insulating element may be made of plastic, rubber, etc.

[0080] The outer casing 22 is a component used to cooperate with the end cap 21 to form the internal environment of the battery cell 20. This internal environment can accommodate the battery cell 23, electrolyte, and other components. The outer casing 22 and the end cap 21 can be independent components. An opening can be provided on the outer casing 22, and the end cap 21 can be used to close the opening to form the internal environment of the battery cell 20. Alternatively, the end cap 21 and the outer casing 22 can be integrated. Specifically, the end cap 21 and the outer casing 22 can form a common connecting surface before other components are inserted into the casing. When it is necessary to encapsulate the interior of the outer casing 22, the end cap 21 closes the outer casing 22. The outer casing 22 can be of various shapes and sizes, such as cuboid, cylindrical, hexagonal prism, etc. Specifically, the shape of the outer casing 22 can be determined according to the specific shape and size of the battery cell 23. The material of the outer casing 22 can be various, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc. This application embodiment does not impose any special limitations on this.

[0081] Cell 23 is the component in the battery cell 20 where the electrochemical reaction occurs. The casing 22 may contain one or more cells 23. Cell 23 is mainly formed by winding or stacking positive and negative electrode plates, and a separator is usually provided between the positive and negative electrode plates. The portions of the positive and negative electrode plates containing active material constitute the main body of the cell assembly, while the portions of the positive and negative electrode plates without active material each constitute tabs 23a. The positive and negative tabs may be located together at one end of the main body or separately at both ends of the main body. During the charging and discharging process of the battery device, the positive and negative active materials react with the electrolyte, and the tabs 23a connect to the electrode terminals 21a to form a current loop.

[0082] See Figure 4 and Figure 5 , Figure 4 This is a partial structural schematic diagram of the water-cooled structure 30 according to some embodiments of this application; Figure 5 This is a cross-sectional view of the water-cooled structure 30 according to some embodiments of this application.

[0083] This application provides a water-cooled structure 30, which includes a water-cooling body 31 and a water nozzle assembly 32. The water-cooling body 31 is provided with a water inlet communicating with its internal flow channel. The water nozzle assembly 32 is detachably mounted on the water-cooling body 31 and maintains electrical communication with the water-cooling body 31. The water nozzle assembly 32 is provided with a through water passage 3211, one end of which is connected to the water inlet, and the other end is used to connect to an external pipeline.

[0084] The water-cooled structure 30 provided in this embodiment includes a water-cooling body 31 and a water nozzle assembly 32. The internal flow channels of the water-cooling body 31 allow fluid to flow and regulate the temperature of the battery cell 20. The water-cooling body 31 is equipped with the water nozzle assembly 32, which connects the water-cooling body 31 to external pipelines via a water passage 3211, allowing fluid to circulate between the water-cooling body 31, the water nozzle assembly 32, and the external pipelines. By maintaining electrical contact between the water nozzle assembly 32 and the water-cooling body 31, electrolytic corrosion occurs on the water nozzle assembly 32, particularly at the connection point between the water nozzle assembly 32 and the external pipelines. Furthermore, by detachably mounting the water nozzle assembly 32 to the water-cooling body 31, it can be quickly replaced in case of corrosion leading to leakage or other damage, thus reducing battery costs.

[0085] Optionally, the water-cooled main body 31 can adopt a water-cooled plate structure, with part of it set inside the box 10 to regulate the temperature of the battery cells 20 inside the box 10; and part of it extending outside the box 10. The water nozzle assembly 32 is generally set on the water-cooled main body 31 extending outside the box 10.

[0086] In some embodiments, the water-cooled body 31 is provided with an inlet and an outlet, and the aforementioned water nozzle assembly 32 is provided at the inlet and outlet respectively.

[0087] See Figure 6 and Figure 7 , Figure 6 This is an exploded structural diagram of the water-cooled structure 30 in some embodiments of this application; Figure 7 for Figure 5 A magnified view of a portion of the center view.

[0088] In some embodiments, the water-cooling structure 30 further includes a counterslip 33, which is disposed on the water-cooling body 31, and the water nozzle assembly 32 is detachably mounted on the counterslip 33. The counterslip 33 is provided with a connecting channel 331, which connects the water inlet and the water passage 3211; wherein, the counterslip 33 is electrically connected to the water nozzle assembly 32. By providing the counterslip 33, it is convenient to assemble the water nozzle assembly 32. By electrically connecting the counterslip 33 to the water nozzle assembly 32, the water nozzle assembly 32 and the water-cooling body 31 are kept at essentially the same potential, so that electrolytic corrosion still occurs at the water nozzle assembly 32, providing good protection for the counterslip 33 and the water-cooling body 31.

[0089] In some embodiments, the faucet assembly 32 includes a connector 322 and a water-passing component 321 with a water passage 3211. The connector 322 is detachably mounted on the counterpart 33, and one end of the water-passing component 321 passes through the connector 322 and is inserted into the connecting channel 331. By providing the water-passing component 321 with the water passage 3211 inserted into the connecting channel 331, the water passage 3211 and the connecting channel 331 are connected to achieve fluid passage communication. At the same time, the connecting channel 331 also serves to position the water-passing component 321, making it easier for the connector 322 to connect with the counterpart 33. Furthermore, by providing the connector 322, which is detachably connected to the counterpart 33, the water-passing component 321 can be securely engaged with the connecting channel 331 or the fixation of the water-passing component 321 can be released.

[0090] Optionally, the water-passing component 321 is constructed as a circular tube, and the connecting component 322 protrudes radially along the water-passing component 321 to form a flange structure.

[0091] In some embodiments, the water-passing component 321 and the connecting component 322 are constructed as a single unit. This allows for integral molding via casting, resulting in good structural strength and faster processing.

[0092] In other embodiments, the water-passing component 321 and the connecting component 322 may also be constructed as separate structures. This is not a limitation, as long as the water-passing component 321 can be fixed by connecting the connecting component 322 to the counter component 33.

[0093] In some embodiments, the water-cooling structure further includes a locking assembly 34, which is configured to lock and fix the connector 322 and the counter 33 to improve the connectivity stability of the water passage 3211 in the water passage 321 and the connecting passage 331 in the counter 33.

[0094] In some embodiments, the locking assembly 34 includes at least two fasteners 341 that connect the connector 322 and the mating member 33, and the at least two fasteners 341 are spaced apart around the connection channel 331. Connecting the connector 322 and the mating member 33 with fasteners 341 can achieve a high connection strength, and the two or more spaced fasteners 341 further improve the reliability of the connection.

[0095] Alternatively, fastener 341 may be a bolt or screw, etc.

[0096] In other embodiments, the locking component 34 may also adopt a structure such as a snap or magnetic attraction, as long as it can firmly connect the connector 322 and the hand member 33. The specific structure is not limited here.

[0097] In some embodiments, the locking assembly 34 is electrically connected to the connector 322; and / or the locking assembly 34 is electrically connected to the opposing component 33. This arrangement allows for good conductivity between the connector 322 and the opposing component 33, reducing electrolytic corrosion in the contact areas between the locking assembly 34 and the opposing component 33, and between the locking assembly 34 and the connector 322. Consequently, electrolytic corrosion occurs at the end of the water-passing component 321 furthest from the opposing component 33, thus providing better protection for the opposing component 33.

[0098] In some embodiments, the connector 322 has a through first connecting hole 3221, and the surface of the opposing member 33 facing the connector 322 has a corresponding second connecting hole 3321, with the second connecting hole 3321 spaced from the surface of the opposing member 33 away from the connector 322. The fastener 341 passes through the first connecting hole 3221 and connects to the second connecting hole 3321. This arrangement makes the second connecting hole 3321 a blind hole. When the fastener 341 passes through the second connecting hole 3321, due to the obstruction of the opposing member 33, the fastener 341 can be separated from the flow channel in the water-cooled body 31, which is more conducive to maintaining isolation from the fluid in the flow channel.

[0099] In some embodiments, a connecting channel 331 is provided through the opponent 33 along a first direction. The opponent 33 has a first surface and a second surface opposite to each other along the first direction. The first surface is connected to the water-cooled body 31, and the second surface is attached to the connector 322 and locked by the locking assembly 34. The first direction is the thickness direction of the water-cooled body 31. During assembly of the water-cooled structure 30, the connecting channel 331 is made to communicate with the water inlet, the first surface of the opponent 33 is connected to the water-cooled body 31, the connector 322 is attached to the second surface of the opponent 33, making the water passage 3211 communicate with the connecting channel 331, and then the connector 322 and the opponent 33 are locked by the locking assembly 34.

[0100] In some embodiments, the actuator 33 includes a connecting body 332 and a locking protrusion 333. The connecting body 332 has a first surface that conforms to the water-cooling body 31 and a second surface that conforms to the connector 322. The locking protrusion 333 protrudes from the first surface, and the connecting channel 331 passes through the connecting body 332 and the locking protrusion 333. When the first surface is in contact with the water-cooling body 31, the locking protrusion 333 engages with the water inlet or outlet of the water-cooling body 31. The actuator 33 can be positioned by engaging the locking protrusion 333 with the water inlet or outlet.

[0101] In some embodiments, the water passage 3211 extends along a first direction, and the water passage member 321 protrudes along the first direction from both sides of the connector 322. Thus, the end of the water passage member 321 that protrudes toward the counterpart member 33 is inserted into the connecting channel 331, while the end that protrudes away from the counterpart member 33 forms a connecting end for connecting to an external pipeline.

[0102] In some embodiments, a sealing element 323 is sandwiched between the water-passing component 321 and the connecting channel 331. By providing the sealing element 323, the sealing performance between the water-passing component 321 and the inner wall of the connecting channel 331 is improved.

[0103] Optionally, the seal 323 may be a sealing ring or a sealing gasket. Multiple seals 323 may be spaced apart along the depth direction of the connecting channel 331 to achieve a better sealing effect.

[0104] Optionally, a sealing element may also be provided at the end of the water-passing component 321 that protrudes away from the counterpart component 33 to improve the sealing performance of the connection between the water-passing component 321 and the external pipeline.

[0105] In some embodiments, the contact element 33 is fixedly connected to the water-cooling body 31. Since the contact element 33 is not easily corroded by electrolytic corrosion, it generally does not need to be replaced, and the fixed connection method is more conducive to improving the connection strength with the water-cooling body 31.

[0106] In some embodiments, the hand component 33 is welded to the water-cooled body 31. This welding method provides high connection strength and good sealing, which is more conducive to improving the connection sealing between the connection channel 331 and the flow channel inside the water-cooled body 31, and reducing leakage.

[0107] In other embodiments, the hand member 33 may also be connected by adhesive or other methods, which are not limited here.

[0108] In some embodiments, a weight-reducing groove 3322 is provided on the hand component 33, and the weight-reducing groove 3322 is offset from the connecting channel 331. By providing the weight-reducing groove 3322, it is beneficial to reduce the weight of the water-cooling structure 30 and save materials.

[0109] In some embodiments, the water tap assembly 32 may be made of aluminum, or more corrosion-resistant stainless steel. The actuator 33 may be made of the same material as the water-cooling body 31, which facilitates welding. Of course, the actuator 33 and the water-cooling body 31 may also be made of different materials; this is not a limitation.

[0110] The water-cooled structure 30 provided in this embodiment includes a water-cooling body 31, a water nozzle assembly 32, a locking component 33, and a fastening component 34. The locking component 33 is disposed on the water-cooling body 31, and the water nozzle assembly 32 is detachably mounted on the locking component 33. The locking component 33 is provided with a connecting channel 331, which connects the water inlet and the water passage 3211 of the water nozzle assembly 32. The locking component 33 and the water nozzle assembly 32 are electrically connected. By keeping the water nozzle assembly 32, the locking component 33, and the water-cooling body 31 electrically connected, electrolytic corrosion occurs on the water nozzle assembly 32, especially at the connection between the water nozzle assembly 32 and the external pipeline. Furthermore, by detachably mounting the water nozzle assembly 32 on the locking component 33, it can be quickly replaced in case of corrosion causing leakage or other damage, which helps reduce battery costs.

[0111] This application also provides a battery, which includes a battery cell 20 and a water-cooling structure 30 as described in any of the above embodiments, the water-cooling structure 30 being used to regulate the temperature of the battery cell 20.

[0112] This application also provides an electrical device that includes a battery as described in any of the above embodiments, the battery being used to provide electrical energy.

[0113] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them.
