Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of batteries, in particular to a battery device and a power utilization device. BACKGROUND

[0002] A battery pack is a rechargeable battery used to provide power for power utilization equipment, and has the advantages of high output, high capacity and light weight. Generally, the battery pack has an optimal working temperature range, in which the working efficiency of the battery pack is relatively high. When the ambient temperature is too high, the temperature of the battery pack is reduced by setting a water cooling plate in the battery pack.

[0003] The condensate generated by the water cooling plate in the related art during use needs to be discharged through a drainage device, which occupies a large space and affects the overall volume of the battery pack. CONTENT OF THE UTILITY MODEL

[0004] In view of the above problems, the present application provides a battery device and a power utilization device, which can solve the problem that the condensate generated by the water cooling plate during use needs to be discharged through a drainage device, which occupies a large space and affects the overall volume of the battery pack.

[0005] To solve the above technical problems, in a first aspect, the present application provides a battery device, comprising:

[0006] a box body, a first liquid discharge port is arranged on the bottom surface of the box body, and the first liquid discharge port is communicated with the outside of the box body;

[0007] a battery cell, the battery cell is arranged in the box body;

[0008] a water cooling plate, the water cooling plate is arranged in the box body, a flow-through area is arranged between the water cooling plate and the first liquid discharge port, and the condensate generated on the water cooling plate is discharged to the outside of the box body through the flow-through area and the first liquid discharge port.

[0009] In the technical scheme of the present application, when the condensate is generated on the water cooling plate, the condensate can be directly discharged to the outside of the box body through the flow-through area and the first liquid discharge port, and the overall device does not need additional equipment to discharge the condensate to the outside, and does not need to occupy additional space.

[0010] In some embodiments, a flow guide surface is arranged on the inner bottom surface of the box body, and the flow guide surface forms the flow-through area;

[0011] the flow guide surface is inclined along a first direction, and the flow guide surface is located at the periphery of the first liquid discharge port, wherein the first direction is the direction from the inner surface to the outer surface of the box body. In this way, when the condensate generated on the water cooling plate falls on the flow-through area, the condensate will quickly flow along the flow guide surface to the first liquid discharge port and be discharged to the outside.

[0012] In some embodiments, the battery device further comprises a baffle, the baffle is arranged on the outer surface of the box, and the baffle is located at the first liquid outlet;

[0013] The baffle can be opened or closed relative to the first liquid outlet. When the liquid in the first liquid outlet reaches a preset weight, the baffle is opened relative to the first liquid outlet. When the liquid in the first liquid outlet is less than the preset weight, the baffle is closed relative to the first liquid outlet. In this way, when the liquid is discharged from the first liquid outlet, the baffle can block the first liquid outlet to prevent external impurities from entering the box.

[0014] In some embodiments, the battery device further comprises a rotating shaft and a torsional spring, the torsional spring is sleeved on the rotating shaft, and the baffle is connected to the outer surface through the rotating shaft. In this way, through the cooperation of the torsional spring and the baffle, the baffle can be opened or closed relative to the first liquid outlet.

[0015] In some embodiments, the battery device further comprises a blocking block, the blocking block is at least partially located in the first liquid outlet, and a size of the blocking block towards one end of the water-cooled plate is greater than an inner diameter of the first liquid outlet;

[0016] The inside of the box is in communication with the outside through the blocking block and the first liquid outlet. In this way, external impurities can be prevented from entering the inside of the box from the first liquid outlet.

[0017] In some embodiments, the blocking block comprises a blocking portion and a column body connected in sequence, a diameter of the blocking portion is greater than a diameter of the first liquid outlet, the blocking portion is located in the inside of the box, and one end of the column body away from the blocking portion is located in the first liquid outlet, and one end of the column body towards the blocking portion is at least partially located outside the first liquid outlet;

[0018] A side surface of the column body is provided with a notch, and the inside of the box is in communication with the outside through the notch.

[0019] In some embodiments, the column body is in interference fit with the first liquid outlet. In this way, the blocking block can be stably located in the first liquid outlet.

[0020] In some embodiments, the battery device further comprises a flow guide block, the flow guide block is arranged on the inside bottom surface of the box, and the flow guide block abuts against a flow channel of the water-cooled plate towards the inside bottom surface of the box;

[0021] The drainage block is provided with a flow guide hole on one side of the inner bottom surface of the box body, the bottom surface of the box body is provided with a second liquid discharge port, and the flow guide hole is in communication with the second liquid discharge port. In this way, the condensed water generated on the water cooling plate can be directly drained to the second liquid discharge port through the drainage block.

[0022] In some embodiments, the position of the drainage block corresponds to the position of the flow channel, and a blank area is formed between two adjacent flow channels, and the position of the blank area corresponds to the position of the glue applying surface on the box body.

[0023] In some embodiments, the drainage block includes at least two fixed blocks and at least one connecting block, the connecting block is located between the two fixed blocks, and the size of the connecting block in a second direction is smaller than the size of the fixed block in the second direction, wherein the second direction is the width direction of the fixed block.

[0024] The fixed block is arranged on the inner bottom surface of the box body, and the flow guide hole is arranged on one side of the connecting block facing the inner bottom surface of the box body.

[0025] An upper surface of the fixed block is provided with a flow guide fin, and the flow guide fin is arranged at an angle relative to the upper surface; when the water cooling plate is arranged in the box body, the flow guide fin abuts against the flow channel.

[0026] Since the flow guide fin is arranged at an angle relative to the upper surface, that is, the flow guide fin is arranged in an inclined structure relative to the upper surface, and the flow guide fin abuts against the flow channel, the condensed water generated on the flow channel can flow away quickly through the flow guide fin.

[0027] In some embodiments, the flow guide fin is located above the flow guide hole in a third direction, and the third direction intersects the second direction. Since the flow guide fin is located above the flow guide hole, the condensed water generated on the flow channel can flow quickly into the flow guide hole through the flow guide fin.

[0028] In some embodiments, the flow guide fin is formed of a flexible material. In this way, when the flow guide fin abuts against the flow channel, the flow guide fin itself will deform, avoiding the situation that the water cooling plate cannot be installed on the box body when the flow guide fin abuts against the flow channel.

[0029] In some embodiments, the distance between the first liquid discharge port and the water inlet on the water cooling plate is less than a threshold value. Since the position of the water inlet on the water cooling plate will generate more condensed water, when the position of the first liquid discharge port corresponds to the position of the water inlet on the water cooling plate, the condensed water generated on the water inlet can be directly discharged to the outside through the first liquid discharge port, avoiding the situation that the condensed water stays in the box body for a long time.

[0030] In some embodiments, the box is provided with a first flange around the periphery thereof, the water-cooling plate is provided with a second flange around the periphery thereof, and the second flange is matched with the first flange.

[0033] When the water-cooling plate is arranged on the box, the part of the water-cooling plate between two adjacent flow channels is bonded to the gluing surface. In this way, the water-cooling plate is stably arranged on the box.

[0034] In some embodiments, the box is provided with a groove on the side thereof away from the water-cooling plate, a projection of the gluing surface along a first direction at least partially overlaps a projection of the groove along the first direction, and the first direction is a direction from the inner surface of the box to the outer surface thereof.

With the continuous expansion of the application field of power battery, the demand of its market is also increasing.

[0067] The battery pack is a rechargeable battery for providing electric energy for electric equipment, which has the advantages of high output, high capacity and light weight. Generally, the battery pack has an optimal working temperature range, and the working efficiency of the battery pack is relatively high within the temperature range. When the environmental temperature is too high, the temperature of the battery pack is reduced by setting a water cooling plate in the battery pack.

[0068] In the related art, condensate water is generated in the water cooling plate during use. In order to drain the condensate water to the outside of the battery pack box, a drainage device needs to be arranged in the box, for example, a water suction pump is arranged in the box to drain the generated condensate water to the outside of the box. Thus, the drainage device occupies the internal space of the box, resulting in a large overall volume of the box.

[0069] Based on the above considerations, in order to solve the problem of condensate water generated during the use of the water-cooled plate, which needs to be discharged through a drainage device, occupying a large space and affecting the overall volume of the battery pack, a battery device is designed, which comprises a box body and a water-cooled plate, wherein the bottom surface of the box body is provided with a first liquid discharge port; the water-cooled plate is arranged in the box body, and a flow-through area is arranged between the water-cooled plate and the first liquid discharge port, and the condensate water generated on the water-cooled plate is discharged to the outside through the flow-through area and the first liquid discharge port.

[0070] Since the first liquid discharge port is arranged in the box body, when condensate water is generated on the water-cooled plate, the condensate water can be directly discharged to the outside after passing through the flow-through area and the first liquid discharge port, and the overall device can discharge the condensate water to the outside without the need for additional equipment and without the need for occupying additional space.

[0071] The battery device in the present application refers to a single physical module comprising one or more battery monomers to provide higher voltage and capacity. For example, the battery device mentioned in the present application can include a battery pack and the like.

In some embodiments, the box body 110 can include a first part 111 and a second part 112, and the first part 111 and the second part 112 are overlapped with each other, and the first part 111 and the second part 112 together define an accommodation space for accommodating the battery cell 120. The second part 112 can be a hollow structure with one end open, and the first part 111 can be a plate-shaped structure, and the first part 111 is overlapped with the open side of the second part 112 to make the first part 111 and the second part 112 together define the accommodation space; the first part 111 and the second part 112 can also be hollow structures with one side open, and the open side of the first part 111 is overlapped with the open side of the second part 112. Of course, the box body 110 formed by the first part 111 and the second part 112 can have various shapes, such as a cylinder, a cuboid, etc.

[0077] In the battery 100, the battery cell 120 can be multiple, and the multiple battery cells 120 can be connected in series, in parallel, or in a mixed connection, where the mixed connection means that the multiple battery cells 120 are connected in series and in parallel. The multiple battery cells 120 can be directly connected in series, in parallel, or in a mixed connection, and then the whole of the multiple battery cells 120 is accommodated in the box body 110; of course, the battery 100 can also be that the multiple battery cells 120 are first connected in series, in parallel, or in a mixed connection to form a battery module, and then the multiple battery modules are connected in series, in parallel, or in a mixed connection to form a whole, and then the whole is accommodated in the box body 110. The battery 100 can also include other structures, for example, the battery 100 can also include a current combing component for realizing the electrical connection between the multiple battery cells 120.

[0078] Each battery cell 120 can be a secondary battery or a primary battery; it can also be a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited thereto. The battery cell 120 can be in the shape of a cylinder, a flat body, a cuboid, or other shapes, etc.

The housing includes a casing 121 having an opening and an end cap 122 closing the opening to isolate an internal environment of the battery cell 120 from an external environment.

[0080] The casing 121 is a component for cooperating with the end cap 122 to form the internal environment of the battery cell 120, where the formed internal environment can be used to accommodate the electrode assembly 123, electrolyte, and other components. The casing 121 and the end cap 122 can be independent components. The casing 121 can be in various shapes and sizes. Specifically, the shape of the casing 121 can be determined according to the specific shape and size of the electrode assembly 123. The material of the casing 121 can be various, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc.

[0081] The end cap 122 refers to a component that covers the opening of the casing 121 to isolate the internal environment of the battery cell 120 from the external environment. Without limitation, the shape of the end cap 122 can be adapted to the shape of the casing 121 to cooperate with the casing 121. Optionally, the end cap 122 can be made of a material with certain hardness and strength (such as aluminum alloy), so that the end cap 122 is not easily deformed when subjected to extrusion collision, so that the battery cell 120 can have higher structural strength, and the reliability can also be improved. The end cap 122 can be provided with functional components such as electrode terminals.

In some embodiments, an insulating structure can also be provided on the inner side of the end cap 122, which can be used to isolate the electrical connection components in the casing 121 from the end cap 122 to reduce the risk of short circuit. Exemplarily, the insulating structure can be plastic, rubber, etc.

[0082] The electrode assembly 123 is a component in which electrochemical reactions occur in the battery cell 120. One or more electrode assemblies 123 can be included inside the case 121. The electrode assembly 123 is mainly formed by winding or stacking a positive electrode sheet and a negative electrode sheet, and a separator film is generally provided between the positive electrode sheet and the negative electrode sheet to separate the positive electrode sheet and the negative electrode sheet to avoid internal short circuiting.

In addition, the electrode assembly 123 can be a wound structure or a stacked structure.

[0083] In some embodiments, the battery cell 120 can also be provided with a pressure relief mechanism for relieving internal pressure when the internal pressure or temperature of the battery cell 120 reaches a threshold value.

[0084] According to some embodiments of the present application, Figure 4 The figure shows the cooperation structure of the box and the water-cooled plate in the present application. As shown in the figure, Figure 4 The present application provides a battery device, which comprises a box 10, a water-cooled plate 11 and a battery cell, wherein the battery cell is arranged in the box 10, the bottom surface of the box 10 is provided with a first drainage port 101, the first drainage port 101 is connected to the outside of the box 10, the water-cooled plate 11 is arranged in the box 10, a flow-through area is provided between the water-cooled plate 11 and the first drainage port 101, and condensed water generated on the water-cooled plate 11 is drained to the outside of the box 10 through the flow-through area and the first drainage port 101.

[0085] The box 10 in the present embodiment is open at the top, and the box 10 can be a rectangular box, a cylindrical box or the like. The specific shape can be determined according to actual conditions, and the present embodiment does not limit this.

[0086] One or more first drainage ports 101 can be arranged on the bottom surface of the box 10, and the specific number can be determined according to actual conditions, and the present embodiment does not limit this.

[0087] In the present embodiment, the water-cooled plate 11 can be fixed to the inner bottom surface of the box 10 by bolts, or the water-cooled plate 11 can be bonded to the inner bottom surface of the box 10. The specific fixing method can be determined according to actual conditions, and the present embodiment does not limit this.

[0088] In the present embodiment, when the water-cooled plate 11 is fixed to the box 10, a gap exists between the water-cooled plate 11 and the box 10, and the gap forms the flow-through area.

[0089] In use, when the water-cooled plate 11 works to generate condensed water, the condensed water drops to the bottom surface inside the box body 10 and is then discharged to the outside of the box body 10 through the first liquid discharge port 101.

[0090] In the technical solution of the embodiment of the application, the first liquid discharge port 101 is arranged in the box body 10. When condensed water generated on the water-cooled plate 11 drops to the bottom surface inside the box body 10, the condensed water can be directly discharged to the outside of the box body 10 through the first liquid discharge port 101. The overall device does not need additional equipment to discharge the condensed water to the outside, and does not need to occupy additional space.

[0091] According to some embodiments of the application, as shown in Figure 5 and in combination with Figure 6 , the bottom surface inside the box body 10 is provided with a flow guide surface 103, the flow guide surface 103 forms a flow-through area, and the flow guide surface 103 is inclined along a first direction, and the flow guide surface 103 is located at the periphery of the first liquid discharge port 101, wherein the first direction is the direction from the inner surface to the outer surface of the box body 10.

[0092] In the embodiment, the first direction is the direction from top to bottom as shown in Figure 5 .

[0093] In the embodiment, the flow guide surface 103 is formed on the inner surface 102 of the box body.

[0094] In the embodiment, the flow guide surface 103 is inclined downward along the direction from top to bottom relative to the inner surface 102.

[0095] In the embodiment, the flow guide surface 103 can be arranged at the periphery of the first liquid discharge port 101, or the flow guide surface 103 can be arranged at at least part of the periphery of the first liquid discharge port 101. The specific arrangement can be determined according to actual conditions, and the embodiment of the specification does not limit the arrangement.

[0096] Since the flow guide surface 103 is inclined downward along the direction from top to bottom relative to the inner surface 102, when the condensed water generated on the water-cooled plate 11 drops to the inner surface 102, the condensed water will quickly flow along the flow guide surface 103 to the first liquid discharge port 101 and be discharged to the outside.

[0097] According to some embodiments of the application, as shown in Figure 6 and in combination with Figure 7 , Figure 8 , Figure 9As shown, the battery device further comprises a baffle 14, which is arranged on the outer surface 104 of the box 10 and located at the first liquid outlet 101; meanwhile, the baffle 14 can be opened or closed relative to the first liquid outlet 101, and the baffle 14 is opened relative to the first liquid outlet 101 when the liquid in the first liquid outlet 101 reaches a preset weight, and the baffle 14 is closed relative to the first liquid outlet 101 when the liquid in the first liquid outlet 101 is less than the preset weight.

[0098] In the embodiment, the baffle 14 can be connected to the outer surface 104 of the box 10 through the cooperation of the rotating shaft and the torsional spring, or the baffle 14 is clamped in the first liquid outlet 101, which can be determined according to actual conditions, and the embodiment of the specification does not limit this.

[0099] The baffle 14 in the embodiment can be circular, square, etc., which can be determined according to actual conditions, and the embodiment of the specification does not limit this.

[0100] In the embodiment, when the baffle 14 is closed relative to the first liquid outlet 101, the baffle 14 can completely block the first liquid outlet 101.

[0101] In use, when the liquid in the first liquid outlet 101 reaches a preset weight, for example, when the liquid in the first liquid outlet 101 exceeds 50g, the baffle 14 will be opened relative to the first liquid outlet 101 under the action of the gravity of the liquid, at this time, the liquid at the first liquid outlet 101 is discharged to the outside. Subsequently, the baffle 14 will be closed relative to the first liquid outlet 101 under its own action, at this time, the baffle 14 completely blocks the first liquid outlet 101, so that external sundries can be prevented from entering the inside of the box from the first liquid outlet 101.

[0102] According to some embodiments of the present application, as Figure 7 As shown, the battery device further comprises a rotating shaft 141 and a torsional spring, which are not marked in the figure, wherein the torsional spring is sleeved on the rotating shaft 141, and the baffle 14 is connected to the outer surface 104 through the rotating shaft 141.

[0103] In the embodiment of the present application, the torsional spring is sleeved on the rotating shaft 141, and the baffle 14 is connected to the outer surface 104 through the rotating shaft 141, which is a prior art and will not be described here.

[0104] Since the torsional spring is sleeved on the rotating shaft 141, and the baffle 14 is connected to the outer surface 104 through the rotating shaft 141, through the cooperation of the torsional spring and the baffle 14, the baffle 14 can be opened or closed relative to the first liquid outlet 101.

[0105] It should be noted that the connection structure of the above-mentioned baffle and the outer surface is only an example, and other structures can also be used in other alternative schemes, for example, the baffle is clamped in the first liquid outlet, etc. The present application does not specially limit the connection structure of the baffle and the outer surface, as long as the above-mentioned material structure can achieve the purpose of the present application.

[0106] According to some embodiments of the present application, as Figure 10 and in combination with Figure 11 It is shown that the battery device further comprises a shielding block 15, which is at least partially located in the first liquid outlet 101, and the size of the shielding block 15 towards one end of the water-cooled plate 11 is greater than the inner diameter of the first liquid outlet 101; the inside of the box body 10 is in communication with the outside through the shielding block 15 and the first liquid outlet 101.

[0107] Referring to Figure 11 It is shown that when the shielding block 15 is set into the first liquid outlet 101, a part of the shielding block 15 is located in the first liquid outlet 101, and another part is located in the inside of the box body 10, and the size of the part of the shielding block 15 located in the inside of the box body 10 is greater than the size of the first liquid outlet 101, the part of the shielding block 15 located in the inside of the first liquid outlet 101 is fixed in the first liquid outlet 101, and the inside of the box body 10 can be in communication with the outside through the shielding block 15 and the first liquid outlet 101.

[0108] In use, when the condensed water generated on the water-cooled plate 11 falls on the inner surface 102, it flows to the shielding block 15 through the flow guide surface 103, and finally is discharged to the outside from the first liquid outlet 101. Since the size of the part of the shielding block 15 located in the inside of the box body 10 is greater than the size of the first liquid outlet 101, external impurities can be prevented from entering the inside of the box body 10 from the first liquid outlet 101.

[0109] According to some embodiments of the present application, as Figure 10 and in combination with Figure 11 It is shown that the shielding block 15 comprises a shielding part 151 and a column 152 connected in sequence, wherein the diameter of the shielding part 151 is greater than the diameter of the first liquid outlet 101, the shielding part 151 is located in the inside of the box body 10, the column 152 is located in the first liquid outlet 101 away from the one end of the shielding part 151, and the one end of the column 152 towards the shielding part 151 is at least partially located outside the first liquid outlet 101; the side surface of the column 152 is provided with a notch 153, and the inside of the box body 10 is in communication with the outside through the notch 153.

[0110] Referring to Figure 11 It is shown that when the first liquid outlet 101 is a circular structure, the column 152 is a cylindrical structure, the column 152 is fixed in the first liquid outlet 101, and the shielding part 151 is fixed above the column 152.

[0111] The embodiment can provide one or more notches 153 on the column 152, which can be determined according to actual conditions, and the embodiment of the specification does not limit this.

[0112] In use, when the condensed water generated on the water-cooled plate 11 falls on the inner surface 102, it flows to the notch 153 through the flow guide surface 103, and finally flows out of the first drainage port 101 to the outside.

[0113] Since the first drainage port 101 is provided with a shielding part 151, the size of the shielding part 151 is larger than the diameter of the first drainage port 101, so that external sundries can be prevented from entering the inside of the box 10 from the first drainage port 101.

[0114] According to some embodiments of the present application, the column 152 is in interference fit with the first drainage port 101. In this way, the column 152 can be stably located in the first drainage port 101.

[0115] Of course, it can be understood that the column 152 can also be in threaded fit with the first drainage port 101, which can be determined according to actual conditions, and the embodiment of the specification does not limit this.

[0116] According to some embodiments of the present application, as shown in Figure 12 and in combination with Figure 13 , Figure 14 , Figure 15 , the battery device further comprises a flow guide block 16, which is arranged on the inner bottom surface of the box 10, and the flow guide block 16 abuts against the flow channel 114 on the inner bottom surface of the box 10 towards the water-cooled plate 11; at the same time, the side of the flow guide block 16 towards the inner bottom surface of the box 10 is provided with a flow guide hole 164, and the bottom surface of the box 10 is provided with a second drainage port 105, and the flow guide hole 164 is in communication with the second drainage port 105.

[0117] The embodiment can include one or more flow guide blocks 16, which can be determined according to actual conditions, and the embodiment of the specification does not limit this.

[0118] The flow guide block 16 in the embodiment can be bonded to the inner surface 102 of the box 10, or the flow guide block 16 can be fixed to the inner surface 102 by bolts, which can be determined according to actual conditions, and the embodiment of the specification does not limit this.

[0119] The side of the flow guide block 16 towards the inner surface 102 is provided with one or more flow guide holes 164, which are in communication with the second drainage port 105.

[0120] When the water-cooled plate 11 is installed on the housing 10, the flow channel 114 on the inner surface 102 of the water-cooled plate 11 will come into contact with the guide block 16. At this time, the condensate generated on the flow channel 114 will flow quickly through the guide block 16 to the guide hole 164, and finally be discharged through the second drain port 105.

[0121] In this embodiment, since a lot of condensate will be generated on the flow channel 114 of the water-cooled plate 11, the large amount of condensate on the flow channel 114 can be quickly discharged to the outside by setting the guide block 16, which is conducive to the rapid discharge of condensate on the flow channel 114.

[0122] According to some embodiments of this application, the position of the flow guide block 16 corresponds to the position of the flow channel 114; such as Figure 15 As shown, a blank area 116 is formed between two adjacent flow channels 114, and the position of the blank area 116 corresponds to the position of the adhesive surface 13 on the housing 10.

[0123] In this embodiment, after the water-cooled plate 11 is placed on the housing 10, the flow channel 114 on the water-cooled plate 11 is located directly above the drainage block 16, and at the same time, the blank area 116 on the water-cooled plate 11 is located directly above the adhesive surface 13. In this way, the drainage block 16 is in complete contact with the flow channel 114, and the condensate generated on the flow channel 114 can be discharged to the outside in large quantities from the drainage block 16.

[0124] According to some embodiments of this application, such as Figure 13 As shown, the flow guide block 16 includes at least two fixing blocks 161 and at least one connecting block 162. The connecting block 162 is located between the two fixing blocks 161. The dimension of the connecting block 162 along the second direction is smaller than the dimension of the fixing block 161 along the second direction, wherein the second direction is the width direction of the fixing block 161. The fixing block 161 is disposed on the bottom surface inside the housing 10, and the flow guide hole 164 is disposed on the side of the connecting block 162 facing the bottom surface inside the housing 10. At the same time, the upper surface 1611 of the fixing block 161 is provided with a flow guide wing 163, which is disposed at an angle relative to the upper surface 1611. When the water cooling plate 11 is disposed on the housing 10, the flow guide wing 163 abuts against the flow channel 114.

[0125] The second direction in this embodiment is as follows: Figure 13 The X-axis direction in the diagram.

[0126] In this embodiment, the guide fin 163 can be a plate-like structure, and the specific structure can be determined according to the actual situation. This specification does not limit this embodiment.

[0127] refer to Figure 13 As shown, an angle α is formed between the guide fin 163 and the upper surface 1611, and the guide fin 163 is inclined upward relative to the upper surface 1611.

[0128] The fixed block 161 in the embodiment can be bonded to the inner surface 102 of the cabinet 10, or the fixed block 161 is fixed to the inner surface 102 by a bolt, which can be determined according to actual conditions, and the embodiment of the specification does not limit this.

[0129] The fixed block 161 and the connecting block 162 in the embodiment can be integrally formed, or the connecting block 162 is clamped on the fixed block 161, which can be determined according to actual conditions, and the embodiment of the specification does not limit this.

[0130] When the water-cooled plate 11 is installed on the cabinet 10, the flow channel 114 on the inner surface 102 of the water-cooled plate 11 will abut against the flow guide fin 163. Since the flow guide fin 163 is in an inclined structure as a whole, at this time, the condensed water generated on the flow channel 114 will quickly flow away through the flow guide fin 163.

[0131] According to some embodiments of the present application, as shown in Figure 13 The flow guide fin 163 is located above the flow guide hole 164 along the third direction, and the third direction intersects the second direction.

[0132] The third direction in the embodiment is the Y-axis direction as shown in Figure 13 The included angle between the X-axis and the Y-axis can be 80°, 85°, 90°, etc., and the embodiment takes the case where the X-axis and the Y-axis are perpendicular to each other as an example.

[0133] As shown in Figure 13 Since the flow guide fin 163 is located above the flow guide hole 164, the condensed water generated on the flow channel 114 of the water-cooled plate 11 can quickly flow into the flow guide hole 164 through the flow guide fin 163, avoiding the retention of condensed water in the inner surface 102.

[0134] According to some embodiments of the present application, the flow guide fin 163 is formed of a flexible material.

[0135] The flexible material in the embodiment can be rubber, polyester, etc., which can be determined according to actual conditions, and the embodiment of the specification does not limit this.

[0136] Since the flow guide fin 163 is formed of a flexible material, when the flow guide fin 163 abuts against the flow channel 114, the flow guide fin 163 itself will deform, avoiding the situation that the water-cooled plate 11 cannot be installed on the cabinet 10 when the flow guide fin 163 abuts against the flow channel 114.

[0137] According to some embodiments of the present application, the distance between the first drain port 101 and the water inlet on the water-cooled plate 11 is less than a threshold value.

[0138] In the embodiment, the water inlet on the water-cooled plate 11 can be located directly above the first liquid outlet 101, in which case the distance between the water inlet on the water-cooled plate 11 and the first liquid outlet 101 is the smallest, or the water inlet on the water-cooled plate 11 is located above the flow guide surface 103, or the water inlet on the water-cooled plate 11 is located at the edge of the flow guide surface 103, in which case the distance between the water inlet on the water-cooled plate 11 and the first liquid outlet 101 is the largest.

[0139] The threshold in the embodiment can be between the minimum distance and the maximum distance.

[0140] Since the position of the water inlet on the water-cooled plate 11 produces more condensed water, when the distance between the first liquid outlet 101 and the water inlet on the water-cooled plate 11 is less than the threshold, the condensed water produced on the water inlet can be quickly discharged to the outside through the first liquid outlet 101, avoiding the condensed water staying in the cabinet 10 for a long time.

[0141] According to some embodiments of the present application, as shown in Figure 4 The periphery of the cabinet 10 is provided with a first flange 106, and the periphery of the water-cooled plate 11 is provided with a second flange 115, which cooperates with the first flange 106.

[0142] In the embodiment, when the water-cooled plate 11 is placed on the cabinet 10, the second flange 115 is attached to the first flange 106, so that by fixing the first flange 106 and the second flange 115, the water-cooled plate 11 can be quickly fixed to the cabinet 10

[0143] According to some embodiments of the present application, as shown in Figure 4 The battery device further comprises a connecting piece 12, which is arranged on the first flange 106, and the second flange 115 is provided with a mounting hole 113, and the connecting piece 12 is located in the mounting hole 113.

[0144] The connecting piece 12 in the embodiment can be a pin shaft, a clamping block, etc., which can be determined according to actual conditions, and the embodiments of the present specification do not limit this.

[0145] Referring to Figure 4 When the water-cooled plate 11 is installed on the cabinet 10, the connecting piece 12 corresponds to the mounting hole 113, so that the water-cooled plate 11 is conveniently fixed to the cabinet 10.

[0146] According to some embodiments of the present application, as shown in Figure 5 and in combination with Figure 15 The side of the cabinet 10 facing the water-cooled plate 11 is provided with a rubberized surface 13; when the water-cooled plate 11 is arranged on the cabinet 10, the part between the adjacent two flow channels 114 on the water-cooled plate 11 is bonded to the rubberized surface 13. In this way, the water-cooled plate 11 can be stably located on the cabinet 10.

[0147] According to some embodiments of the present application, as shown in Figure 8 The side of the box 10 away from the water-cooling plate 11 is provided with a groove 107, and the projection of the glue applying surface 13 along the first direction at least partially coincides with the projection of the groove 107 along the first direction, the first direction being the direction from the inner surface to the outer surface of the box 10.

[0148] The first direction in the present embodiment can refer to the above description, which will not be repeated here.

[0149] In the present embodiment, the glue applying surface 13 is located on the inner surface 102 of the box 10, the groove 107 is located on the outer surface 104 of the box 10, and the groove 107 is located directly below the glue applying surface 13 along the first direction. In this way, the overall thickness of the box 10 at the position of the glue applying surface 13 can be avoided, and the weight of the overall box 10 can be reduced.
