[0052] The present application provides an energy storage container for storing electrical energy and supplying power externally.

[0053] The specific embodiments of the energy storage container of the present application are described in detail below with reference to the accompanying drawings.

[0054] Figure 1 Part of the structure of the energy storage container in the present embodiment is shown in the schematic diagram.

[0055] Reference Figure 1The energy storage container 100 comprises a container 110 and at least one electrical equipment 120.

[0056] The container 110 comprises a box body and a box door. The box body is hollow inside and has an opening on one side. The box door is rotatably connected to the opening end of the box body and is used to open and close the opening of the box body.

[0057] Figure 2 FIG. 2 is a structural schematic diagram of the electrical equipment 120 in the embodiment.

[0058] Referring to Figure 1 and Figure 2 The electrical equipment 120 comprises an electrical cabinet 1 and a heat dissipation structure 2.

[0059] The electrical cabinet 1 is arranged in the container 110. The electrical cabinet 1 comprises a cabinet body 11, a cabinet door 12 and electrical components.

[0060] The cabinet body 11 is hollow inside and has an opening on one side. The cabinet door 12 is hinged to the opening end of the cabinet body 11 and is used to open and close the opening of the cabinet body 11. The electrical components are arranged inside the cabinet body 11. The electrical components can be energy storage batteries, inverters, transformers, controllers, charging machines, etc.

[0061] The electrical cabinet 1 has a ventilation opening for the hot air inside the electrical cabinet 1 to be dissipated outward. Specifically, the ventilation opening is arranged at the top of the cabinet body 11 and communicates with the inside of the cabinet body 11.

[0062] The cabinet body 11 is provided with an air inlet 13 which communicates with the inside of the cabinet body 11 and is used for air intake of the cabinet body 11. Specifically, the air inlet 13 is located at the lower part of the cabinet body 11.

[0063] In actual application, when the electrical equipment 120 is in a working state, the electrical components inside the cabinet body 11 continuously generate heat, and the air in the cabinet body 11 expands and rises due to heat absorption. At this time, the design of arranging the ventilation opening at the top of the cabinet body 11 can facilitate the dissipation of hot air, and at the same time, the air with lower temperature outside enters the cabinet body 11 through the air inlet 13 at the lower part of the cabinet body 11, continues to exchange heat with the electrical components to absorb heat and expand and rise, and is dissipated through the ventilation opening, thereby realizing heat exchange from bottom to top in the inside of the cabinet body 11, improving the heat exchange effect and heat dissipation effect in the inside of the cabinet body 11, cooling the electrical components, and ensuring that the inside of the cabinet body 11 is in a suitable temperature environment, so as to ensure that the electrical components can operate normally at rated power.

[0064] The heat dissipation structure 2 is used for heat dissipation of the electrical equipment 120. Specifically, the heat dissipation structure 2 is used for dissipating the heat generated by the electrical components in the inside of the cabinet body 11 to the outside of the container 110 in time, so as to ensure that the temperature in the inside of the cabinet body 11 is suitable and the electrical components can work normally.

[0065] Figure 3 Fig. 2 is a perspective view of the heat dissipation structure 2 in the embodiment, Figure 4 Fig. 3 is a side view of the heat dissipation structure 2 in the embodiment.

[0066] Referring to Figures 1 to 4 , the heat dissipation structure 2 includes a heat dissipation assembly 21 and a window assembly 22. The heat dissipation assembly 21 is arranged inside the container 110, and has a first heat dissipation channel 2111, a first end of the first heat dissipation channel 2111 being configured to communicate with the air vent of the electrical equipment 120. The window assembly 22 is arranged on the container 110, and has a second heat dissipation channel 2211, a first end of the second heat dissipation channel 2211 communicating with a second end of the first heat dissipation channel 2111, and a second end of the second heat dissipation channel 2211 being open to the outside.

[0067] In actual application, the heat dissipation structure 2 in the present application can make the hot air inside the electrical equipment 120 enter the first heat dissipation channel 2111 through the air vent, and then be dissipated to the outside through the second heat dissipation channel 2211 communicating with the first heat dissipation channel 2111. In this way, the heat generated by the electrical equipment 120 can be discharged to the outside of the container 110 in time, so as to avoid the heat of the electrical equipment 120 from gathering in the container 110, and ensure that the electrical equipment 120 can keep normal operation at rated power, thereby improving the use performance of the electrical equipment 120.

[0068] Figure 5 Fig. 4 is a structural view of the heat dissipation assembly 21 in the embodiment, Figure 6 Fig. 5 is an exploded structural view of the heat dissipation assembly 21 in the embodiment.

[0069] Referring to Figures 2 to 6 , the heat dissipation assembly 21 is arranged on the top of the electrical cabinet 1. The heat dissipation assembly 21 has the first heat dissipation channel 2111, and a first end of the first heat dissipation channel 2111 communicates with the air vent.

[0070] In the embodiment, the heat dissipation assembly 21 includes a shell 211 and a fan 212.

[0071] The shell 211 is connected and fixed with the top of the cabinet body 11. Specifically, the shell 211 is connected and fixed with the cabinet body 11 through fasteners. The bottom outer periphery of the shell 211 is arranged with an annular member 214, which protrudes outward from the outer periphery of the shell 211 in the horizontal direction, so as to be attached to the top of the cabinet body 11. A plurality of connecting holes are arranged at intervals on the annular member 214, the top of the cabinet body 11 is provided with a plurality of mounting holes, the distribution positions of the plurality of connecting holes correspond to the distribution positions of the plurality of mounting holes one by one, and a fastener is arranged in each connecting hole and the corresponding mounting hole. The fastener is screwed with the shell 211 and the cabinet body 11, so as to realize the connection and fixation of the shell 211 and the cabinet body 11.

[0072] The shell 211 is hollow inside, and the bottom of the shell 211 is provided with a first heat dissipation opening 2112 communicating with the inside of the shell 211, and one side of the shell 211 along the first direction is provided with a second heat dissipation opening 2113 communicating with the inside of the shell 211, thereby forming the first heat dissipation channel 2111. The shell 211 has a first end and a second end, the first end is one end of the shell 211 provided with the first heat dissipation opening 2112, and the first heat dissipation opening 2112 communicates with the air vent. The second end is one end of the shell 211 provided with the second heat dissipation opening 2113. It should be noted that the first end of the shell 211 is the first end of the first heat dissipation channel 2111, and the second end of the shell 211 is the second end of the first heat dissipation channel 2111.

[0073] The first direction herein is a direction perpendicular to the vertical direction in the horizontal plane.

[0074] In this embodiment, the second end of the shell 211 can be flush with the same side end of the cabinet 11 along the first direction, or the second end of the shell 211 can extend outward beyond the end of the cabinet 11 along the first direction.

[0075] Specifically, the shell 211 includes a top plate, a side plate, two end plates, wherein the two end plates are arranged at the two ends of the side plate along the second direction, and the two end plates are located on the same side of the side plate along the first direction, and the top plate is connected to the top of the side plate and the two end plates. In this embodiment, the upper part of the side plate is arc-shaped, and the concave surface of the arc-shaped surface faces the second heat dissipation opening 2113. This design uses the smooth curve of the arc line to solve the problem of poor ventilation of hot air at the corner, improve the smoothness of the flow of hot air, and thus improve the heat dissipation effect. The second direction herein is a direction perpendicular to the first direction in the same horizontal plane.

[0076] The shell 211 can also include a bottom plate connected to the bottom of the side plate and the two end plates, and the bottom plate is provided with the first heat dissipation opening 2112.

[0077] When the second end of the shell 211 extends to be flush with the open end of the cabinet 11 or extends outward beyond the open end of the cabinet 11, the shell 211 can also include a bent plate connected between the two end plates, and the bent plate and the side plate are arranged at the two ends of the end plate along the first direction. Specifically, the bent plate includes a vertical part and a horizontal part, the vertical part is erected on the end plate, the horizontal part is connected to the top of the vertical part, and the horizontal part protrudes out of the vertical part along the horizontal direction towards the direction of the cabinet door 12. In this way, the horizontal part is spaced above the cabinet door, that is, the above design can make the second end of the shell 211 spaced above the cabinet 11, so as to avoid the cabinet 11 and the cabinet door 12, and ensure that the cabinet door 12 can be smoothly rotated.

[0078] ReferenceFigure 5 and Figure 6 The fan 212 is arranged inside the second end of the first heat dissipation channel 2111, and serves as a power source to suck the hot air inside the cabinet 11. Specifically, the fan 212 is located inside the first heat dissipation channel 2111 and at the second heat dissipation port 2113.

[0079] The fan 212 is fixedly connected with the shell 211. Specifically, the heat dissipation assembly 21 further comprises a fixing plate 213 connected with the shell 211, and the fixing plate 213 is provided with a through hole. The fan 212 is fixedly connected with the fixing plate 213 and is opposite to the through hole, so that the hot air sucked by the fan 212 can be dissipated through the through hole while the installation of the fan 212 is achieved.

[0080] The fan 212 is electrically connected with the electrical components inside the cabinet 11, that is, the fan 212 is powered by the structure of the electrical equipment 120 itself, so that the electrical equipment 120 can be self-powered.

[0081] In this embodiment, the fan 212 can be an axial fan 212. At this time, the fan 212 is fixedly connected to the inner side of the fixing plate 213, and the fan 212 is distributed opposite to the through hole.

[0082] Figure 7 FIG. 4 is a structural schematic view of the heat dissipation assembly 21 in other embodiments.

[0083] Referring to Figure 7 In other embodiments, the fan 212 can also be a centrifugal fan 212. At this time, the fan 212 is arranged through the through hole and is fixedly connected with the fixing plate 213.

[0084] The type of the fan 212 can be selected according to the wind resistance between the electrical components and the heat dissipation structure 2 outside the cabinet 11. For example, for the case of relatively low wind resistance, an axial fan 212 can be used to generate a relatively large amount of air to improve the amount of air dissipated per unit time. For the case of relatively high wind resistance, a centrifugal fan 212 can be used to better overcome the wind resistance and generate a relatively large amount of air to improve the amount of air dissipated per unit time, so as to meet the heat dissipation requirements of the electrical equipment 120.

[0085] Referring to Figure 4 and Figure 5In the embodiment, the number of the fans 212 can be multiple, and the multiple fans 212 are distributed along the horizontal direction to simultaneously act on the hot air inside the cabinet body 11 to improve the heat dissipation efficiency of the electrical equipment 120. Specifically, a plurality of through holes are arranged on the fixed plate 213, and the multiple fans 212 are arranged one by one in the through holes. Each fan 212 is arranged at a corresponding through hole and is fixedly connected with the fixed plate 213. In other embodiments, the number of the fans 212 can be one. The number of the fans 212 can be increased or decreased according to the heat dissipation requirement of the electrical equipment 120.

[0086] In the embodiment, the multiple fans 212 can be installed in series. The series installation can improve the pressure of the fans 212 to adapt to the heat dissipation requirement of the electrical equipment 120 with large air resistance.

[0087] Referring to Figure 1 The window assembly 22 is arranged on the container 110. Specifically, the container 110 is provided with a mounting hole, and the window assembly 22 is arranged at the mounting hole and is fixedly connected with the container 110.

[0088] For example, the window assembly 22 can be arranged on the door of the container 110. In other embodiments, the window assembly 22 can also be arranged on the side wall of the container 110.

[0089] Referring to Figures 2 to 4 In the embodiment, the window assembly 22 is detachably connected with the heat dissipation assembly 21. When the window assembly 22 is arranged on the door, the window assembly 22 can be rotated to be close to and abut against the shell 211 of the heat dissipation assembly 21, or the window assembly 22 can be rotated to be away from the heat dissipation assembly 21.

[0090] That is, the heat dissipation structure 2 in the embodiment is composed of the window assembly 22 and the heat dissipation assembly 21 which are independent of each other. This facilitates the removal of the electrical cabinet 1 and the heat dissipation assembly 21 from the container 110. Meanwhile, during the arrangement of the electrical cabinet 1 in the container 110, the heat dissipation assembly 21 arranged on the electrical cabinet 1 and the window assembly 22 arranged on the container 110 can be easily abutted.

[0091] And, the heat dissipation assembly 21 is sealingly connected with the window assembly 22. Exemplarily, the second end of the heat dissipation assembly 21 is provided with a sealing member 23, and the sealing member 23 is annularly arranged at the outer periphery of the second end of the first heat dissipation channel 2111. Wherein, the window assembly 22 is pressure-connected with the sealing member 23 on the heat dissipation assembly 21 to compress the sealing member 23, so as to realize the sealing connection between the window assembly 22 and the heat dissipation assembly 21, which can avoid the hot air extracted by the heat dissipation assembly 21 from leaking and flowing back to the inside of the cabinet 11, thereby improving the heat dissipation effect and efficiency of the electrical equipment 120. Specifically, the first end of the window assembly 22 is annularly provided with an abutting member 24, which is arranged corresponding to the sealing member 23, and the abutting member 24 abuts against the sealing member 23, so as to further ensure that the outer periphery of the joint between the window assembly 22 and the heat dissipation assembly 21 is sealed, thereby enhancing the sealing effect.

[0092] In other embodiments, the sealing member 23 can also be arranged at the first end of the window assembly 22, and the sealing member 23 is annularly arranged at the outer periphery of the second heat dissipation channel 2211. Wherein, the heat dissipation assembly 21 is pressure-connected with the sealing member 23 on the window assembly 22 to compress the sealing member 23, so as to realize the sealing connection. At this time, an abutting member 24 is annularly arranged at the outer periphery of the second end of the heat dissipation assembly 21, and the abutting member 24 is distributed at the outer periphery of the second heat dissipation port 2113.

[0093] Wherein, the sealing member 23 is a rubber strip, that is, when the window assembly 22 is connected with the heat dissipation assembly 21, the rubber strip is compressed to tightly fit the abutting member 24, so as to realize the tight connection between the window assembly 22 and the heat dissipation assembly 21.

[0094] Figure 8 The structure of the window assembly 22 in the embodiment is shown in the following figure, Figure 9 The exploded structure of the window assembly 22 in the embodiment is shown in the following figure.

[0095] Reference Figure 8 and Figure 9In the embodiment, the window assembly 22 has a second heat dissipation channel 2211, and a second end of the second heat dissipation channel 2211 is communicated with the outside. When the window assembly 22 is connected with the heat dissipation assembly 21, the first end of the second heat dissipation channel 2211 is communicated with the second end of the first heat dissipation channel 2111, so as to cooperate with the first heat dissipation channel 2111 to flow the heat dissipation air. Meanwhile, when the window assembly 22 is located at the second end of the shell 211 of the heat dissipation assembly 21, the window assembly 22 can also play a protection role on the fan 212 located at the second end of the shell 211, so as to prevent rain, dust and the like from entering the first heat dissipation channel 2111 and interfering with the work of the fan 212, thereby ensuring the normal work of the fan 212 and the heat dissipation effect and efficiency of the electrical equipment 120. Alternatively, the window assembly 22 can rotate away from the heat dissipation assembly 21 to expose the second heat dissipation port 2113, so as to facilitate the maintenance, cleaning, replacement, disassembly and the like of the fan 212 in the shell 211 through the second heat dissipation port 2113, thereby facilitating the operation.

[0096] In the embodiment, the window assembly 22 includes a shell 221, and the shell 221 is connected and fixed with the container 110. The shell 221 is hollow inside to form the second heat dissipation channel 2211. Exemplarily, the shell 221 includes four surrounding plates which are sequentially connected in a head-to-tail manner to form a frame structure with a rectangular cross section, and the four surrounding plates form the second heat dissipation channel 2211.

[0097] At this time, the first end of the second heat dissipation channel 2211 in the above is an end of the shell 221 close to the heat dissipation assembly 21 in a direction perpendicular to the side wall of the container 110 or the door of the container 110, and the second end of the second heat dissipation channel 2211 is an end facing the outside of the container 110, and the same below.

[0098] In the embodiment, opposite sides of the shell 221 perpendicular to the side wall of the container 110 or the door of the container 110 are respectively provided with a third heat dissipation port 2212 and a fourth heat dissipation port 2213 communicated with the second heat dissipation channel 2211. That is, the third heat dissipation port 2212 and the fourth heat dissipation port 2213 are arranged at two ends of the frame formed by the four surrounding plates.

[0099] The arrangement position of the third heat dissipation port 2212 corresponds to the arrangement position of the second heat dissipation port 2113, and the shape and size of the third heat dissipation port 2212 are matched with the shape and size of the second heat dissipation port 2113, so as to facilitate the connection and communication of the two.

[0100] In this embodiment, the caliber of the second end of the second heat dissipation passage 2211 is smaller than the caliber of the first end of the second heat dissipation passage 2211, so that the resistance of the airflow in the second heat dissipation passage 2211 can be reduced, the flow performance of the airflow is improved, and thus the second heat dissipation passage 2211 has a better heat dissipation effect. That is, the caliber of the third heat dissipation port 2212 is smaller than the caliber of the fourth heat dissipation port. Exemplarily, the inner diameter of the shell 221 can gradually increase from the first end to the second end, so that the shell 221 is at least partially in a flared shape.

[0101] With reference to Figure 8 and Figure 9 , the window assembly includes an exhaust window 222, and the exhaust window 222 includes a window frame 2221 and a plurality of window leaves 2222. The window frame 2221 is arranged at the second end of the second heat dissipation passage 2211 and is fixedly connected with the shell 221. Specifically, the window frame 2221 is a rectangular frame structure.

[0102] The plurality of window leaves 2222 are vertically spaced apart in the window frame 2221, and adjacent two window leaves 2222 and the window frame 2221 form an exhaust window identical to the second heat dissipation passage 2211, so that the hot air in the second heat dissipation passage 2211 can pass through and be dissipated outward.

[0103] Figure 10 For Figure 9 , FIG. 6 is a sectional view of the exhaust window 222 along the A-A direction.

[0104] With reference to Figures 8 to 10 , in this embodiment, the window leaves 2222 are fixedly connected with the window frame 2221. Specifically, the two ends of the window leaves 2222 are fixedly connected with the window frame 2221. Each window leaf 2222 is inclined outward from top to bottom, or each window leaf 2222 extends along the horizontal direction, so as to play a role of waterproof and dustproof.

[0105] In other embodiments, each window leaf 2222 is rotatably connected with the window frame 2221, and the window leaf 2222 can rotate relative to the window frame 2221 to adjust the inclination angle thereof, so as to adjust the air exhaust amount; or, the window leaf 2222 can open and close the air exhaust window, so as to realize the on-off control of the fourth heat dissipation port 2213. Specifically, the window leaf 2222 can rotate between the vertical extension and the horizontal extension, i.e., the rotation angle range thereof is 0°-90°. Specifically, the upper middle portion of the window leaf 2222 is rotatably connected with the window frame 2221. The window leaf 2222 has a first end and a second end, when the window leaf 2222 extends in the horizontal direction, the first end is located at the inner side of the second end, and when the window leaf 2222 extends in the vertical direction, the first end is located above the second end. In the process of rotating from the vertical extension to the horizontal extension, the first end of each window leaf 2222 is pressed downward, and the second end is lifted upward, so as to expose and enlarge the air exhaust window between the adjacent two window leaves 2222, in addition, in the process, each window leaf 2222 is in a state of being inclined outward from top to bottom or extending in the horizontal direction, which can also play a role in preventing water and dust. If it is needed to reduce the air exhaust window between the adjacent two window leaves 2222, the window leaf 2222 can be rotated in a direction opposite to the above direction.

[0106] Reference Figure 10 In the embodiment, the lower end portion of each window leaf 2222 is provided with a lower baffle 223, which is located below the window leaf 2222 and is used for guiding rainwater, so as to prevent the rainwater from falling along the window leaf located above to the window leaf located below, and splashing into the inside of the second heat dissipation channel 2211, thereby playing a role in preventing water.

[0107] In the embodiment, the lower baffle 223 extends in the vertical direction, so that the water falls vertically along the lower baffle 223.

[0108] In other embodiments, the lower baffle 223 can also be inclined outward from top to bottom. At this time, the included angle between the lower baffle 223 and the vertical direction is smaller than the included angle between the window leaf 2222 and the vertical direction, so that the water slides outward from top to bottom along the lower baffle 223.

[0109] In the embodiment, the upper end portion of each window leaf 2222 is provided with a stop piece 224, which includes an upper baffle 2241 extending in the horizontal direction, and the upper baffle 2241 is located outside the upper end portion of the window leaf 2222, and is used for stopping rainwater from flowing into the second heat dissipation channel 2211.

[0110] The stop piece 224 also includes a connecting plate 2242 connected between the window leaf 2222 and the upper baffle 2241, the connecting plate 2242 extends in the vertical direction, and forms a cofferdam at the top of the window leaf 2222, so as to further enhance the effect of the stop piece 224 in stopping water.

[0111] In the embodiment, the window leaf 2222 is integrally bent and formed with the lower baffle 223 and the stopper 224.

[0112] In the embodiment, the window assembly 22 further comprises a filter 225, which is arranged at the exhaust window and inside the exhaust window 222 to block dust particles from entering the inside of the second heat dissipation channel 2211.

[0113] In the embodiment, the electrical equipment 120 can further comprise a heat dissipator arranged on the cabinet body 11 or the cabinet door 12 to dissipate the hot air inside the cabinet body 11 to the outside. Specifically, a perforation is arranged on the cabinet body 11 or the cabinet door 12 and communicates with the inside of the cabinet body 11, and the heat dissipator is arranged at the perforation and connected and fixed with the cabinet body 11 or the cabinet door 12.

[0114] The heat dissipator can act simultaneously with the heat dissipation structure 2 to dissipate heat of the electrical equipment 120, and the cooperation of the two can enhance the heat dissipation effect and efficiency of the electrical equipment 120. Alternatively, the heat dissipator or the heat dissipation structure 2 can be selected to be turned on according to the heat dissipation requirement of the electrical equipment 120, that is, the heat dissipator and the heat dissipation structure 2 are turned on one by one to save energy consumption.

[0115] In the embodiment, the heat dissipator is an exhaust fan.

[0116] In other embodiments, the electrical equipment 120 can also be provided without the heat dissipator to simplify the structure of the electrical equipment 120 and increase the effective utilization space of the electrical equipment 120.

[0117] From the above technical solutions, the utility model has at least the following advantages and positive effects:

[0118] In the application, the heat dissipation structure is arranged to dissipate the heat generated by the electrical equipment arranged inside the container to the outside of the container in time, so that the temperature inside the electrical equipment is suitable.

[0119] Specifically, the heat dissipation structure is composed of a heat dissipation assembly and a window assembly which are independent of each other. The heat dissipation assembly is arranged inside the container and its first heat dissipation channel communicates with the ventilation port of the electrical equipment. The window assembly is arranged on the container, and the second heat dissipation channel of the window assembly is used to communicate the first heat dissipation channel with the outside of the container. In actual application, the hot air inside the electrical equipment can enter the first heat dissipation channel through the ventilation port and then be dissipated to the outside through the second heat dissipation channel which communicates with the first heat dissipation channel. In this way, the heat generated by the electrical equipment can be discharged to the outside of the container in time, the heat of the electrical equipment is prevented from gathering in the container, the temperature of the electrical equipment is reduced, and the electrical equipment can keep normal operation at rated power, so as to improve the use performance of the electrical equipment.
