[0026] In the energy storage system provided above, a condensation collection device can be used to collect liquid condensed in the second air outlet area of the air duct body, thereby achieving water vapor separation of the cold air entering the condensation collection device from the second air outlet area. This is beneficial for preventing liquid in the second air outlet area from flowing along the heat dissipation air duct, effectively preventing condensed liquid from entering the box, and helping to reduce the humidity of the air inside the box. This can also prevent the insulation resistance of the energy storage unit in the box from being reduced due to excessive humidity in the air. Therefore, the energy storage system provided by this embodiment is beneficial for reducing the risk of leakage and / or fire in the energy storage unit.

[0027] In some possible implementations, the condensation collection device includes a shell, a deflector and a condensation receiving piece, the shell has a vertically arranged air passage, the top end of the air passage is connected to the air inlet, and the bottom end of the air passage is the air outlet; the air passage has a first side and a second side relative to each other, the condensation receiving piece is arranged on the first side in the air passage, the deflector is arranged on the second side of the air passage relative to the horizontal plane, the height of the side of the deflector close to the condensation receiving piece in the vertical direction is a first height, the height of the side of the deflector away from the condensation receiving piece in the vertical direction is a second height, the second height is greater than the first height, and at least a portion of the side of the deflector close to the condensation receiving piece is located above the condensation receiving piece.

[0028] In the energy storage system provided above, the air passage is vertically arranged and the top of the air passage is connected to the air inlet, so that the liquid condensed at the cold outlet of the air duct body can enter the air passage from the air inlet. The guide plate is arranged in the air passage, so that the liquid condensed at the cold outlet of the air duct body can drip onto the guide plate. The guide plate is tilted, so that the liquid dripping on the guide plate can flow along the guide plate to the side of the guide plate close to the condensation receiving piece. Furthermore, at least a portion of the side of the guide plate close to the condensation receiving piece is located above the condensation receiving piece, so that the liquid on the guide plate can flow directly along the guide plate to the condensation receiving piece, and then the liquid at the second air outlet area of the air duct body is collected by the condensation receiving piece to prevent the liquid condensed at the second air outlet area from entering the battery cluster along the heat dissipation air duct.

[0029] In some possible implementations, the deflector includes a plurality of deflector plates, and the plurality of deflector plates are spaced apart and distributed in the air passage along a first direction, wherein the first direction is inclined downward from a first side of the air passage to a second side of the air passage;

[0030] In each guide plate, the height of the side close to the first side of the wind channel in the vertical direction is less than the height of the side away from the first side of the wind channel in the vertical direction; and two adjacent guide plates include a first guide plate and a second guide plate, the first guide plate is away from the first side of the wind channel, and the second guide plate is close to the first side of the wind channel; the side of the first guide plate close to the first side of the wind channel is at least partially located above the second guide plate.

[0031] In the energy storage system provided above, the guide plate includes a plurality of guide plates, and the plurality of guide plates are spaced apart in the air duct along a first direction, so that the airflow can flow through the gap between two adjacent guide plates, thereby achieving water vapor separation, and the flow direction of water and the flow direction of cold air are divided into two. Each guide plate is arranged at an angle, so that the liquid on the guide plate can flow along the guide plate to the adjacent guide plate close to the condensation receiving member, and then can flow one by one along the guide plate to the condensation receiving member. In this way, on the one hand, it is beneficial to increase the uniformity of the airflow in various places in the heat dissipation duct, and thus beneficial to the uniformity of the cold air entering various places in the battery cluster. On the other hand, it is also beneficial to increase the flow area of the heat dissipation duct and reduce the resistance of the wind shield to the airflow.

[0032] In some possible implementations, the extension surfaces of any two or more deflector plates are parallel to each other, which is beneficial for improving the stability of the airflow used for heat dissipation at various locations in the energy storage system.

[0033] In some implementations, the angle between the extended surface of the deflector plate and the horizontal plane is 30° to 70°. This not only ensures that the liquid on the deflector plate can flow along the deflector plate into the condensation collector, but also helps prevent backflow caused by obstruction by the deflector plate.

[0034] In some possible implementations, the condensation receiving member includes a liquid receiving portion and a drain pipe, the liquid receiving portion has a receiving groove, the groove opening of the receiving groove is opposite to the side of the guide plate close to the first side of the air passage; the drain pipe is connected to the receiving groove, and the liquid in the receiving groove is discharged along the drain pipe.

[0036] In some implementations, the first end of the receiving tank is connected to the drain pipe, and the bottom of the receiving tank is tilted toward the first end of the receiving tank. This embodiment is beneficial for draining all the liquid in the receiving tank and preventing the liquid that flows down from the guide plate from accumulating in the receiving tank.

[0037] In some achievable embodiments, the second air outlet area is vertically downward, which is beneficial for allowing condensed liquid in the second air outlet area to directly fall onto the guide plate, thereby facilitating rapid collection of the liquid.

[0038] In some possible implementations, the energy storage system also includes an adjustment device, which is arranged in the second air outlet area. The adjustment device includes a plurality of wind shields, which are arranged in parallel and at intervals on the duct main body. The wind shield is rotatably connected to the duct main body, and at least a portion of the wind shield is opposite to the second air outlet area. The second air outlet area is oriented in the second direction. The wind shield switches between a first position and a second position relative to the duct main body. When the wind shield is in the first position relative to the duct main body, the area of the projection of the wind shield in the second direction is the first area. When the wind shield is in the second position relative to the duct main body, the area of the projection of the wind shield in the second direction is the second area. The second area is larger than the first area and the adjustment device is used to adjust the air volume and / or air outlet direction of the cold air outlet.

[0039] The energy storage system can adjust the air volume and / or air outlet direction of the second air outlet area through the adjustment device, thereby adjusting the size of the air inlet volume of the heat dissipation duct to adjust the heat dissipation capacity.

For example, they may refer to fixed connection, detachable connection, or integration; they may refer to direct connection or indirect connection through an intermediate medium; they may refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0061] It should be noted that in the description of the present invention, the terms "first" and "second" are used solely to facilitate description of different components and should not be construed as indicating or implying a sequential relationship, relative importance, or implicitly specifying the number of technical features being referred to. Therefore, features defined as "first" or "second" may explicitly or implicitly include at least one such feature.

[0062] In the related art, the air outlet of the air duct used for heat dissipation of the battery cluster is prone to condensation to form water droplets, and the formed water droplets are easy to enter the battery cluster along the air duct, thereby causing high air humidity in the battery cluster, reducing the insulation resistance of the battery cluster to the ground, and increasing the risk of battery cluster leakage and fire.

[0063] In response to the above technical problems, an embodiment of the present invention provides an energy storage system, including a box 10, in which at least one energy storage unit 11, at least one air conditioner 20 and at least one air duct body 100 are arranged. The cold air inlet of the air duct body 100 is connected to the air conditioner 20, and the air duct body 100 includes: a shell, an air duct extending along a first direction is provided in the shell, the air duct includes a flow balancing chamber and a flow rectifying chamber, the flow balancing chamber and the flow rectifying chamber are arranged along a second direction, and one end of the flow balancing chamber is used to circulate with the exhaust port of the air conditioner; a plurality of equally spaced first air outlet areas are provided between the flow balancing chamber and the flow rectifying chamber, and each first air outlet area has a corresponding The same first air outlet, the flow balancing chamber and the rectifying chamber are connected through the first air outlet; the inner bottom surface of the rectifying chamber is provided with a plurality of unequally spaced second air outlet areas along the first direction, each second air outlet area is provided with at least one second air outlet, the second air outlet area 110 is vertically downward, and the first direction is perpendicular to the second direction; it also includes a condensation collection device 200, the condensation collection device 200 includes an air inlet 210 and an air outlet 220 connected to the air inlet 210, the air inlet 210 is connected to the second air outlet area 110 of the air duct main body 100, and the air outlet 220 and the energy storage unit 11 are arranged at corresponding positions.

[0064] Figure 2-4 This is a schematic diagram of the air duct structure provided by an embodiment of the present invention. Figure 2 As shown, the air duct structure provided by the embodiment of the present invention may include: a shell A, wherein the shell A has a first direction (eg Figure 1 The air duct B extends in the x direction in the second direction (eg, the x direction in the second direction), and the air duct B includes a flow balancing cavity 111 and a flow rectifying cavity 112. The flow balancing cavity 111 and the flow rectifying cavity 112 extend in the second direction (eg, the x direction in the second direction). Figure 1 For example, in the second direction, the rectifying cavity 112 is located in the front and the flow balancing cavity 111 is located in the rear. One end of the flow balancing cavity 111 is used to communicate with the exhaust port of the air conditioner (not shown), so that the cold air discharged from the exhaust port of the air conditioner first enters the flow balancing cavity 111 of the air duct B.

[0065] Among them, see Figure 3As shown, there are a plurality of first air outlet areas 1111 arranged at equal intervals between the flow balancing cavity 111 and the rectifying cavity 112, for example Figure 1 In the embodiment of the present application, 12 first air outlet areas 1111 are provided, wherein the interval between two adjacent first air outlet areas 1111 is P1, and the interval between two adjacent second air outlet areas is P2, then P1 = P2. That is, in the embodiment of the present application, the interval between any two adjacent first air outlet areas 1111 is the same.

[0066] Each first air outlet area 1111 has the same first air outlet 1112, and the flow balancing chamber 111 and the rectifying chamber 112 are connected via the first air outlet 1112. Thus, the cold air discharged from the air conditioner first enters the flow balancing chamber 111 for flow balancing, and then enters the rectifying chamber 112 through the first air outlet 1112. The rectifying chamber 112 mixes and rectifies the cold air discharged from each first air outlet 1112.

[0067] It should be noted that each first air outlet area 1111 has the same first air outlet 1112. Specifically, each first air outlet area 1111 has the same number and shape of first air outlets 1112. In this way, when the cold air discharged by the air conditioner enters the flow equalizing cavity 111, the flow equalizing cavity 111 has a flow equalizing effect on the cold air, and each first air outlet area 1111 is arranged at equal intervals, thereby ensuring that the air outlet volume of each first air outlet area 1111 is uniform.

[0068] In order to achieve heat dissipation for battery cabinets arranged at non-equidistant intervals, in the embodiment of the present application, the inner bottom surface 1123 of the rectifier cavity 112 has a plurality of second air outlet areas 110 with non-equidistant intervals along the first direction, for example Figure 1 , 12 second air outlet areas 110 are shown, and the intervals between two adjacent second air outlet areas 110 in the 12 second air outlet areas 110 are L1, L2, L3, L4, L5, L6, L7, L8, L9, L10, L11, and L12, respectively. Of course, in some examples, the multiple second air outlet areas 110 may be arranged at unequal intervals: some of L1, L2, L3, L4, L5, L6, L7, L8, L9, L10, L11, and L12 may be the same, while others may be different. For example, L1 = L2 ≠ L3 ≠ L4 ≠ L5 ≠ L6 ≠ L7 = L8 ≠ L9 ≠ L10 ≠ L11 ≠ L12. The spacing between L1, L2, L3, L4, L5, L6, L7, L8, L9, L10, L11, and L12 may be adjusted according to the unequally spaced battery cabinets.

[0069] Each second air outlet area 110 has at least one second air outlet 1122, for example, Figure 1 In the embodiment, each second air outlet area 110 is provided with eight second air outlets 1122. Of course, in some examples, six, five, or other second air outlets 1122 may be provided in the second air outlet area 110 as needed. The number of second air outlets 1122 is determined based on specific needs. The airflow within the rectifier cavity 112 is discharged out of the rectifier cavity 112 through the second air outlets 1122, and then discharged to the top of each battery cabinet for heat dissipation.

[0070] In this embodiment of the present application, by providing multiple, unequally spaced second air outlet areas 110 on the inner bottom surface 1123 of the rectifier cavity 112, heat dissipation can be achieved for battery cabinets arranged at different intervals. This avoids the cumbersome and time-consuming on-site adjustment required for manual air direction adjustment, as well as the complex and time-consuming manufacturing associated with the provision of special-shaped air ducts B. It is understood that the air duct B structure provided in this embodiment of the present application can also dissipate heat for battery cabinets arranged at equal intervals.

[0071] It can be understood that in order to ensure that the air volume in each second air outlet area 110 is uniform, the number and shape of the second air outlets 1122 on each second air outlet area 110 can be the same, or the total opening area of the second air outlets 1122 on each second air outlet area 110 can be the same, so that the air volume on each second air outlet area 110 is consistent.

[0072] It should be noted that Figure 1 12 second air outlet areas 110 and 12 first air outlet areas 1111 are shown. Of course, in some examples, the number of second air outlet areas 110 and first air outlet areas 1111 in the air duct B structure provided in the present application includes but is not limited to 12, for example, it can also be 20 or 18, etc.

[0073] It can be understood that the second air outlet areas 110 and the first air outlet areas 1111 can be in one-to-one correspondence, and the number of the second air outlet areas 110 and the number of the first air outlet areas 1111 can be the same.

[0074] Therefore, the air duct B structure provided in the embodiment of the present application includes a shell A, and the shell A has an air duct B extending along the first direction. The air duct B includes a flow balancing chamber 111 and a rectifying chamber 112. The flow balancing chamber 111 and the rectifying chamber 112 are arranged along the second direction. One end of the flow balancing chamber 111 is used to circulate with the exhaust port of the air conditioner. There are multiple equally spaced first air outlet areas 1111 between the flow balancing chamber 111 and the rectifying chamber 112. Each first air outlet area 1111 has the same first air outlet 1112. The flow balancing chamber 111 and the rectifying chamber 112 are connected through the first air outlet 1112. The inner bottom surface 1123 of the rectifying chamber 112 has multiple unequally spaced second air outlet areas 110 along the first direction. Each second air outlet area 110 has at least one second air outlet 1122. The first direction is perpendicular to the second direction. In this way, The flow equalizing chamber 111 can evenly distribute the wind flow in each first air outlet area 1111. A plurality of equally spaced first air outlet areas 1111 and the first air outlet areas 1111 have the same first air outlet 1112, ensuring that the flow rate of the air outlets of each first air outlet area 1111 is uniform. The rectifying chamber 112 rectify the air flow blown out of the first air outlet 1112. The non-equally spaced second air outlet areas 110 and the second air outlet 1122 on the second air outlet area 110 form unequally spaced exhaust areas on the inner bottom surface 1123 of the rectifying chamber 112, thereby fully cooling the battery cabinets arranged at unequal intervals, ensuring that the air outlets of the duct B structure are flexibly arranged according to the positions of the battery cabinets, and avoiding the time-consuming, labor-intensive and cumbersome operation caused by manual adjustment of the guide plates or shutters on site to dissipate heat for the battery cabinets at unequal intervals. Therefore, the air duct B structure provided in this application realizes the heat dissipation requirements of various equidistant or unequally spaced battery cabinets, ensures uniform flow distribution at each air outlet, and solves the problem of time-consuming, labor-intensive and cumbersome operation caused by manual adjustment of the guide plate or blinds in the existing air duct B.

[0075] In one possible implementation, see Figure 2-3 As shown, a partition 130 is provided in the air duct B. The partition 130 is arranged along the first direction (x direction). The partition 130 divides the air duct B into a flow-distributing cavity 111 and a flow-rectifying cavity 112. That is, the flow-distributing cavity 111 and the flow-rectifying cavity 112 are separated by the partition 130. A plurality of equally spaced first air outlet areas 1111 are provided on the partition 130, and a plurality of first air outlets 1112 are provided on the first air outlet area 1112. For example Figure 1 In the embodiment, eight second air outlets 1122 are provided on the first air outlet area 1111. Of course, in some examples, the number of the second air outlets 1122 includes but is not limited to eight, and five or four second air outlets 1122 may also be provided.

[0076] In one possible implementation, see Figure 2-3As shown, each first air outlet area 1111 is provided with a deflector 1113. The deflector 1113 is located within the rectifier cavity 112. One end (the rotating end) of the deflector 1113 is rotatably connected to the inner edge of the first air outlet area 1111, and the other end of the deflector 1113 is a free end. The free end of the deflector 1113 rotates horizontally around the rotating end. The deflector 1113 can adjust the wind direction of the first air outlet 1112 to prevent excessive local airflow caused by excessive wind direction.

[0077] It should be noted that since the guide plate 1113 is located in the rectifier chamber 112, the rotation angle of the guide plate 1113 can often be adjusted before installation. If it needs to be adjusted during use, it is often difficult to adjust it manually. Therefore, the rotation angle of the guide plate 1113 can be adjusted automatically, for example, by setting a motor and a rotating shaft to automatically adjust the rotation angle of the guide plate 1113.

[0078] It can be understood that in order to ensure that the air output of each first air outlet 1112 is uniform, the rotation angle of the guide plate 1113 set in each first air outlet area 1111 is often the same, which ensures that the air outlet direction of each first air outlet area 1111 is consistent.

[0079] In one possible implementation, see Figure 2 As shown, the flow equalizing cavity 111 is an arc-shaped flow equalizing cavity 111 with one side facing the first air outlet 1112. For example, one inner wall of the flow equalizing cavity 111 is an arc-shaped inner wall, which can adjust the static pressure inside the air duct B so that the flow of each first air outlet 1112 is uniform.

[0080] In one possible implementation, see Figure 2 As shown, the flow balancing chamber 111 has an arcuate guide surface 1114, which is opposite to the first air outlets 1112. The arcuate guide surface 1114 and a portion of the inner wall of the flow balancing chamber 111 form the arcuate flow balancing chamber 111. By providing the arcuate guide surface 1114, the static pressure at each first air outlet 1112 in the air duct B can be adjusted to ensure uniform flow at each first air outlet 1112.

[0081] See also Figure 2 As shown, the arc-shaped guide surface 1114 can be an arc-shaped concave surface, so that after the cold air discharged from the air outlet of the air conditioner enters the flow equalizing cavity 111, it can be evenly distributed in the flow equalizing cavity 111 under the guidance of the arc-shaped guide surface 1114.

[0082] In a possible implementation, the first air outlet 1112 is a strip-shaped air outlet, and the two ends of the strip-shaped air outlet are respectively facing the inner bottom surface 1123 and the inner top surface of the shell A. Figure 1 In the embodiment, the first air outlet 1112 is extended along the z direction.

[0083] In one possible implementation, each second air outlet area 110 has a plurality of second air outlets 1122 arranged along the first direction, and the number of second air outlets 1122 opened on each second air outlet area 110 is the same. This ensures that the air output of each second air outlet area 110 is uniform.

[0084] In one possible implementation, see Figure 2 As shown, the second air outlet 1122 is a strip-shaped air outlet, and the strip-shaped air outlet is extended along the second direction (y direction).

[0085] In one possible implementation, it also includes: a connector C, which is a hollow structure. For example, there is a flow channel inside the connector C. One end of the connector C is connected to the shell A, and the interior of the connector C is connected to the flow equalization chamber 111. The other end of the connector C is connected to the exhaust port of the air conditioner.

[0086] See also Figure 4 As shown, the internal flow channel of the connector C comprises a horizontal flow channel 121 and an inclined flow channel 122, one end of the horizontal flow channel 121 being connected to the air outlet of the air conditioner, and one end of the inclined flow channel 122 being connected to the flow equalizing chamber 111. The provision of the inclined flow channel 122 can buffer the airflow entering the flow equalizing chamber 111, preventing the cold air discharged from the air outlet of the air conditioner from having an excessively high pressure at the entrance of the flow equalizing chamber 111, thereby preventing the first air outlet area 1111 near the entrance of the flow equalizing chamber 111 from having an excessively high air volume.

[0087] The air conditioning system provided in the embodiments of the present application dissipates heat from multiple battery cabinets arranged at equal or unequal intervals within an energy storage container, ensuring even distribution of airflow within each first air outlet area 1111. This eliminates the time-consuming, labor-intensive, and cumbersome operation associated with manually adjusting guide plates 1113 or louvers in existing air ducts B. The air duct B structure and air conditioning system provided in the embodiments of the present invention address the issue of excessive dust and sand inside industrial air conditioners in windy and sandy regions, significantly reducing their service life and effectiveness. The system also provides for air flow guidance, rain protection, and dust accumulation prevention.

[0088] It should be noted here that the numerical values and numerical ranges involved in this application are approximate values. Due to the influence of the manufacturing process, there may be a certain range of errors. Those skilled in the art may consider this part of the error to be negligible.

[0093] Preferably, the condensation collecting device 200 includes a housing 230, a guide plate 240 and a condensation receiving member 250.

[0094] The housing 230 has a vertically arranged air passage 231 , the top end of the air passage 231 is connected to the air inlet 210 , and the bottom end of the air passage 231 is the air outlet 220 ;

[0095] The air passage 231 has a first side and a second side opposite to each other. The condensation receiving member 250 is disposed on the first side of the air passage 231. The deflector 240 is disposed on the second side of the air passage 231 relative to a horizontal plane. The vertical height of the side of the deflector 240 close to the condensation receiving member 250 is a first height, and the vertical height of the side of the deflector 240 away from the condensation receiving member 250 is a second height. The second height is greater than the first height. In addition, at least a portion of the side of the deflector 240 close to the condensation receiving member 250 is located above the condensation receiving member 250. The deflector 240 includes a plurality of deflector plates 241. The plurality of deflector plates 241 are spaced apart and distributed in the air passage 231 along a first direction. The first direction is inclined downward from the first side of the air passage 231 to the second side of the air passage 231.

[0096] In each deflector plate 241, the height of the side close to the first side of the air passage 231 in the vertical direction is smaller than the height of the side away from the first side of the air passage 231 in the vertical direction; and

[0097] The two adjacent deflector plates 241 include a first deflector plate and a second deflector plate. The first deflector plate is away from the first side of the air passage 231 , and the second deflector plate is close to the first side of the air passage 231 .

[0098] Preferably, the condensation receiving part 250 includes a liquid receiving portion 251 and a drain pipe 252, the liquid receiving portion 251 has a receiving groove 2511, the groove opening of the receiving groove 2511 is opposite to the side of the first side of the guide plate 240 close to the air passage 231; the drain pipe 252 is connected to the receiving groove 2511, and the liquid in the receiving groove 2511 is discharged along the drain pipe 252; the first end of the receiving groove 2511 is connected to the drain pipe 252, and the bottom of the receiving groove 2511 is inclined toward the first end of the receiving groove 2511.

[0100] Preferably, it further includes an adjustment device 300, which is disposed in the second air outlet area 110.

[0101] The regulating device 300 includes a plurality of windshields 310, which are arranged in parallel and at intervals on the air duct body 100. The windshields 310 are rotatably connected to the air duct body 100, and at least a portion of the windshields 310 is opposite to the second air outlet area 110. The second air outlet area 110 is oriented in the second direction.

[0102] The windshield 310 switches between a first position and a second position relative to the air duct main body 100.

[0104] Preferably, a filter device is further included. The air duct body 100 has a cold air inlet. The filter device is arranged in the air duct body 100 and is located between the cold air inlet and the second air outlet area 110 .

[0105] The energy storage system of the present invention includes a box for accommodating energy storage units, an air conditioner disposed in the box, an air duct main body, and a condensation collection device. The air conditioner is used to generate cold air for cooling, and the air duct main body is connected to the cold air end of the air conditioner so that the cold air generated by the air conditioner enters the air duct main body. A condensation collector is disposed at the cold air outlet of the air duct main body to collect liquid condensed at the cold air outlet through the condensation collection device, thereby preventing the liquid condensed at the cold air outlet from entering the space between the storage units in the box. This is beneficial in preventing the condensed liquid from entering the box, reducing the humidity of the air in the battery cluster, and thereby preventing the insulation resistance of the battery cluster to the ground from being reduced due to excessive humidity in the air. Therefore, the energy storage system provided by this embodiment can solve the problem of high humidity in the air inside the battery cluster that dissipates heat through air cooling, which is prone to leakage and fire.

[0106] The following specific embodiments are used to describe in detail the technical solution of the present invention and how the technical solution of the present invention solves the above technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. Figures 1 to 12 , an embodiment of the present invention is described.

[0107] In some optional embodiments, such as Figure 1 As shown, the energy storage system includes a box 10, an air conditioner 20, an air duct body 100 and a condensation collection device 200. For example, the box 10 is a basic structural component that can provide a mounting base for other components.

[0108] Optionally, the housing 10 includes multiple energy storage units 11 spaced apart from each other, so that ventilation gaps can be formed between adjacent energy storage units 11. This allows airflow into the gaps between the energy storage units 11 to remove heat generated by the energy storage units 11. Exemplarily, the energy storage units 11 can be battery clusters. Specifically, the energy storage units 11 are electrochemical energy storage battery clusters.

[0109] In some optional embodiments, the air conditioner 20 and the air duct body 100 are disposed within the housing 10. The air conditioner 20 can be used to generate cold air. Furthermore, the air duct body 100 is optionally connected to the cold air end of the air conditioner 20. The air duct body 100 has a second air outlet area 110 that communicates with the interior of the housing 10. This allows the cold air generated by the air conditioner 20 to flow along the air duct body 100 into the housing 10, thereby removing heat generated by the energy storage units 11 within the housing 10. Furthermore, the temperature of the cold air generated by the air conditioner 20 can be adjusted as needed to adjust the heat dissipation capacity of the energy storage system.

[0110] It should be noted that in some optional embodiments, the greater the external energy supply or charging power of the energy storage system, the more heat the energy storage system generates. Furthermore, the temperature of the cold air outlet of the air conditioner 20 can be controlled based on the external energy supply or charging power of the energy storage system, thereby adjusting the heat dissipation capacity of the energy storage system according to the amount of heat generated by the energy storage system. This helps maintain each energy storage unit 11 in the energy storage system at a preset temperature, thereby ensuring the normal operation of each energy storage unit 11 and improving the energy storage performance of the energy storage unit 11.

[0111] In some optional embodiments, the condensation collection device 200 is disposed in the air duct main body 100 , and the condensation collection device 200 includes an air inlet 210 and an air outlet 220 connected to the air inlet 210 , and the air inlet 210 is connected to the second air outlet area 110 .

[0112] It should be noted that the temperature of the gas in the air duct main body 100 is lower than the temperature of the gas in the box 10, and then at the second air outlet area 110, the gas in the air duct main body 100 meets the gas in the box 10, and then easily condenses to form droplets at the second air outlet area 110.

[0113] In the above embodiment, the condensation collection device 200 is disposed at the second air outlet area 110. This condensation collection device 200 can collect droplets generated in the second air outlet area 110, preventing the droplets generated there from entering the housing 10. This helps reduce the humidity of the air within the housing 10, thereby preventing the insulation resistance of the battery cluster to ground from being reduced due to excessive humidity. Therefore, the energy storage system provided by this embodiment can address the issue of high humidity within a battery cluster, which can easily lead to electrical leakage and fire.

[0114] In some optional embodiments, the condensation collection device 200 includes a housing 230, a guide plate 240, and a condensation receiving member 250. The housing 230 is a basic structural member that can provide a mounting base for the guide plate 240 and the condensation receiving member 250.

[0115] In some optional embodiments, the housing 230 has a vertically disposed air passage 231, the top end of which is connected to the air inlet 210, and the bottom end of the air passage 231 is the air outlet 220. Further optionally, the air passage 231 has a first side and a second side opposite each other. The condensation container 250 is disposed on the first side of the air passage 231, and the deflector 240 is disposed on the second side of the air passage 231 relative to a horizontal plane. The side of the deflector 240 proximate to the condensation container 250 has a first vertical height, and the side of the deflector 240 distal to the condensation container 250 has a second vertical height, the second height being greater than the first height. Furthermore, at least a portion of the side of the deflector 240 proximate to the condensation container 250 is located above the condensation container 250.

[0116] Illustratively, the deflector 240 is spaced apart from the condensation container 250 so that gas can flow through the gap between the deflector 240 and the condensation container 250. In some optional embodiments, the deflector 240 is located above the condensation container 250, i.e., the vertical height of the deflector 240 on the side near the condensation container 250 is greater than the vertical height of the condensation container 250. At least a portion of the side of the deflector 240 near the condensation container 250 is located above the condensation container 250, i.e., the vertical projection of the side of the deflector 240 near the condensation container 250 at least partially covers the condensation container 250. This allows liquid on the deflector 240 to flow along the deflector 240 to the condensation container 250 under the action of gravity, thereby preventing liquid at the second air outlet area 110 of the air duct body 100 from entering the housing 10.

[0117] Therefore, this solution helps reduce the humidity of the air entering the housing 10, thereby preventing the battery cluster's insulation resistance from decreasing due to excessive humidity. Therefore, the energy storage system provided by this embodiment can address the issue of high humidity within a battery cluster, which can easily lead to electrical leakage and fire.

[0118] In some optional embodiments, the deflector 240 includes a plurality of deflector plates 241, which are spaced apart and distributed within the air passage 231 along a first direction, wherein the first direction is inclined downward from the first side of the air passage 231 to the second side of the air passage 231. In each deflector plate 241, the side closer to the first side of the air passage 231 is vertically shorter than the side farther from the first side of the air passage 231.

[0119] In this way, the liquid condensed in the second air outlet area 110 of the air duct body 100 can fall onto the deflector plate 241 under the action of gravity, and can flow along the deflector plate 241 from the side away from the first side of the air passage 231 to the side close to the first side of the air passage 231. In addition, the multiple deflector plates 241 are arranged at intervals, thereby forming an airflow channel between two adjacent deflector plates 241. On the one hand, this helps reduce the obstruction of the deflector plates 240 to the airflow, and on the other hand, it also helps increase the flow area of the condensation collection device 200 and improve the uniformity of the airflow in the air passage 231.

[0120] In a further optional embodiment, two adjacent deflector plates 241 include a first deflector plate and a second deflector plate, wherein the first deflector plate is away from the first side of the air passage 231, and the second deflector plate is close to the first side of the air passage 231. The side of the first deflector plate close to the first side of the air passage 231 is at least partially located above the second deflector plate. That is, the projection of the side of the first deflector plate close to the first side of the air passage 231 in the vertical direction at least partially covers the second deflector plate. In this way, it can be ensured that the liquid on the first deflector plate can flow along the first deflector plate to the second deflector plate in the direction of gravity. Therefore, in the above embodiment, the liquid on each deflector plate 241 can flow along multiple deflector plates 241 to the condensation receiving member 250.

[0121] In some optional embodiments, the extended surfaces of any two or more deflector plates 241 are parallel to each other. In further optional embodiments, the vertical spacing between any two adjacent deflector plates 241 is equal. In further optional embodiments, the vertical gap between two adjacent deflector plates 241 is 1.5 cm to 15 cm. This helps improve the smoothness of the airflow within the air passage 231.

[0122] In some optional embodiments, the angle between the extension surface of the deflector plate 241 and the horizontal plane is 30° to 70°. In this way, the liquid on the deflector plate 241 can flow downward along the deflector plate 241 and then flow into the condensation receiving member 250 along the deflector plate 241.

[0123] In some optional embodiments, the angle between the extension surface of the deflector plate 241 and the horizontal plane is 60°, which is beneficial for the fluid on the deflector plate 241 to slide along the deflector plate 241 .

[0124] In some optional embodiments, a guide groove is provided on the guide plate 241, and the guide groove extends from the higher side of the guide plate 241 in the vertical direction to the lower side of the guide plate 241 in the vertical direction. In this way, the guide groove can be used to guide the liquid on the guide plate 241. Further optionally, the height of the guide groove perpendicular to its extension direction is 1mm to 10mm. This is beneficial to increase the adsorption force between the liquid and the guide plate 241, and thus to utilize the surface tension of the liquid so that the liquid adheres to the guide plate 241 and flows downward, thereby preventing the liquid on the guide plate 241 from dripping before flowing to the lowest side of the guide plate 241. In addition, this embodiment can also use the guide groove to reduce the impact force of the droplets dripping on the guide plate 241 and the guide plate 241, thereby preventing the droplets from splashing after dripping on the guide plate 241, and thus preventing the liquid from entering the box 10.

[0125] In some optional embodiments, the condensation container 250 includes a liquid receiving portion 251 and a drain pipe 252. The liquid receiving portion 251 has a receiving groove 2511. The notch of the receiving groove 2511 is opposite to the first side of the deflector 240 near the air passage 231. The drain pipe 252 is connected to the receiving groove 2511, and the liquid in the receiving groove 2511 is discharged along the drain pipe 252.

[0126] In the above embodiment, the guide plate 240 can be used to converge the liquid droplets condensed at the second air outlet area 110 of the air duct main body 100 to the condensation receiving part 250. Exemplarily, the guide plate 240 can be used to converge the liquid droplets condensed at the second air outlet area 110 of the air duct main body 100 to the liquid receiving part 251. Specifically, the guide plate 240 can be used to converge the liquid droplets condensed at the second air outlet area 110 of the air duct main body 100 to the receiving groove 2511 of the liquid receiving part 251. The drain pipe 252 is connected to the receiving groove 2511, so that the liquid can be discharged along the drain pipe 252. In this way, on the one hand, it is beneficial to reduce the evaporation amount of the liquid, and on the other hand, it is beneficial to continuously collect the liquid condensed in the second air outlet area 110 to avoid the condensation receiving part 250 being filled with the collected liquid.

[0127] In some optional embodiments, the first end of the receiving tank 2511 is connected to the drain pipe 252, and the bottom of the receiving tank 2511 is inclined toward the first end of the receiving tank 2511. This is beneficial for draining all the liquid in the receiving tank 2511 and avoiding liquid accumulation in the receiving tank 2511.

[0128] In some optional embodiments, the second air outlet area 110 faces vertically downward. For example, the air inlet 210 of the condensation collection device 200 is vertically opposed to the second air outlet area 110. In further optional embodiments, the deflector 240 is opposed to the air inlet 210. This embodiment facilitates liquid in the second air outlet area 110 to drip directly onto the deflector 240.

[0129] In some optional embodiments, the energy storage system further includes a regulating device 300, which is disposed in the second air outlet area 110 to adjust the air volume and direction in the second air outlet area 110. In some optional embodiments, the regulating device 300 includes a plurality of windshields 310, which are disposed in parallel and at intervals in the air duct body 100 so that cold air can flow out from between two adjacent windshields 310. In some optional embodiments, the windshields 310 are rotatably connected to the air duct body 100, and at least a portion of the windshields 310 is opposite the second air outlet area 110, so that the flow area of the second air outlet area 110 can be adjusted by rotating the windshields 310, thereby adjusting the air volume at the second air outlet area 110.

[0130] In some optional embodiments, the second air outlet area 110 is oriented in a second direction. The wind shield 310 switches between a first position and a second position relative to the duct body 100. When the wind shield 310 is in the first position relative to the duct body 100, the projected area of the wind shield 310 in the second direction is the first area. When the wind shield 310 is in the second position relative to the duct body 100, the projected area of the wind shield 310 in the second direction is the second area, which is larger than the first area.

[0131] The larger the projected area of the windshield 310 in the second direction, the larger the area of the windshield 310 shielding the second air outlet area 110, and thus the larger the flow area of the second air outlet area 110. Therefore, by rotating the windshield 310, the projected area of the windshield 310 in the second direction can be increased to reduce the flow rate in the second air outlet area 110. Alternatively, by rotating the windshield 310, the projected area of the windshield 310 in the second direction can be reduced to increase the flow rate in the second air outlet area 110.

[0132] In some optional embodiments, the adjustment device 300 further includes a frame seat 320 and a synchronization rod 330. Exemplarily, the frame seat 320 is disposed on the air duct body 100 and along the edge of the second air outlet area 110. Further optionally, a slide groove 321 is provided on the frame seat 320, and at least a portion of the windshield 310 is located within the slide groove 321. The windshield 310 can slide along the slide groove 321 relative to the frame seat 320 and rotate relative to the frame seat 320. Exemplarily, a cylindrical transfer portion is provided on the windshield 310, and the cylindrical assembly portion is at least partially located within the slide groove 321, so that the cylindrical assembly portion can slide along the slide groove 321 and rotate within the slide groove 321.

[0133] Further optionally, the synchronization rod 330 is rotatably connected to the plurality of windshields 310, so that the synchronization rod 330 can achieve synchronous movement and / or rotation of the plurality of windshields 310 relative to the frame 320. In some optional embodiments, the synchronization rod 330 is threadedly engaged with the frame 320, so that by rotating the synchronization rod 330, the plurality of windshields 310 can be driven to move and / or rotate relative to the frame 320. Exemplarily, a handle is provided at one end of the synchronization rod 330, and rotating the handle can drive the synchronization rod 330 to rotate relative to the frame 320, thereby driving the windshields 310 to move and / or rotate relative to the frame 320.

[0134] The above embodiment is not only helpful in reducing the difficulty of adjusting the adjustment mechanism, but also helpful in ensuring that the wind shields 310 in the adjustment device 300 remain parallel, thereby helping to ensure the consistency of the air volume in various locations in the second air outlet area 110 .

[0135] In some optional embodiments, the energy storage system further includes a filter device. The air duct body 100 has a cold air inlet. The filter device is disposed within the air duct body 100 and is located between the cold air inlet and the second air outlet area 110. Optionally, the filter device can be a filter screen disposed within the air duct body 100.
