Description

Technical Field

[0001] This invention relates to the field of energy storage cabinets, and in particular to a distributed commercial energy storage cabinet. Background Technology

[0002] The batteries in the energy storage cabinet store electrical energy, which can be generated by photovoltaic solar panels or charged by mains power. If the energy storage cabinet is used as a backup power source, it can be understood as a large power bank. When the mains power fails, the energy storage cabinet can provide power. Generally, energy storage cabinets are in the kWh (unit of energy, 1 kWh = 1 kilowatt-hour) range. Customers can select the appropriate size energy storage cabinet according to the power consumption of their load.

[0003] Existing commercial energy storage cabinets generate heat during the charging and discharging of their internal battery boxes. Therefore, heat dissipation components are needed to cool the interior of the cabinet and ensure the normal operation of the battery boxes. Current heat dissipation components for energy storage cabinets typically use electric fans to accelerate air circulation between the inside and outside of the cabinet. However, in high-temperature environments, the temperature of the air entering the cabinet becomes excessively high, placing the battery boxes inside the cabinet in a high-temperature environment as well. Consequently, the heat dissipation efficiency decreases during the air circulation process, making it impossible to effectively cool the battery boxes. Summary of the Invention

[0004] To address the aforementioned issues, this application provides a distributed commercial energy storage cabinet.

[0005] To achieve the above objectives, this application provides the following technical solution: a distributed commercial energy storage cabinet, including a cabinet, with support beams detachably installed at the four corners of the cabinet's inner cavity, multiple sets of support platforms arranged on the support beams, and energy storage battery boxes provided on each support platform for charging and discharging operations, multiple sets of grooves opened on the back of the cabinet, extension frames fixed to the inner walls of the grooves, and multiple flow channels opened on the surface of the extension frames.

[0006] The extension rack is protruding, and an air guiding component is provided on the inner side of the extension rack to guide external air into the inside of the cabinet. The air guiding component is equipped with a cooling component to reduce the temperature of the air entering the cabinet cavity from the external environment.

[0007] Furthermore, the air guiding assembly includes a contact plate, and a heat insulation plate is disposed in front of the contact plate. Both the contact plate and the heat insulation plate have through holes on their surfaces.

[0008] The contact plate and the heat insulation plate are connected to each other on opposite sides by multiple docking pipes. Both ends of the docking pipes are fixed to the inner wall of the through hole. After some airflow in the external environment passes through the flow channel, it is guided by the contact plate to the inside of the docking pipes until it passes through the heat insulation plate and enters the inner cavity of the cabinet.

[0009] Furthermore, the air guiding assembly also includes a detachable inner fixed arm connected to the contact plate, an electric fan is installed at the center of the inner fixed arm, and an isolation frame is connected to the surface of the heat insulation plate via a support foot, the isolation frame being located in front of the electric fan.

[0010] Furthermore, the cooling component includes a cooling pipe containing water. The cooling pipe has multiple covering parts and flow parts. The covering parts are annular tubular structures and are embedded in the connecting pipe. Adjacent covering parts in the horizontal and vertical directions are connected by flow parts. The flow parts are straight pipe structures, and the covering parts and flow parts are interconnected.

[0011] Furthermore, the surface of the contact plate is provided with multiple arc-shaped flow guide grooves, and the inner wall of each arc-shaped flow guide groove is fixed with a first adsorption layer. The flat part of the contact plate near the flow channel is fixed with multiple second adsorption layers. The first adsorption layers and the second adsorption layers are arranged alternately, and the first adsorption layer is provided with a circular hole that matches the through hole.

[0012] Furthermore, a pair of limiting strips are fixed to the inner wall of the extension frame, and a docking channel adapted to the limiting strips is opened on the surface of the contact plate. When the contact plate is installed in the inner cavity of the extension frame, the limiting strips are engaged with the inner side of the docking channel.

[0013] Furthermore, a pair of positioning rods are fixed to the top of the inner wall of the extension frame, and an embedded rod is slidably connected to the outer surface of the positioning rod. The surface of the contact plate is provided with a groove that matches the embedded rod. When the contact plate is installed in the inner cavity of the extension frame, the embedded rod is inserted into the inner wall of the groove, and a paddle is fixed on the outer wall of the embedded rod.

[0014] Furthermore, a water inlet is provided above the cooling pipe.

[0015] In summary, the technical effects and advantages of this invention are as follows:

[0016] This invention guides the airflow outside the cabinet, accelerating air circulation between the inside and outside of the cabinet to dissipate heat from the energy storage battery box. In hot weather, it cools the high-temperature airflow entering the cabinet and contacting the energy storage battery box, thus driving the cooled airflow to cool the battery box. This improves the heat dissipation effect of the airflow entering the cabinet, effectively avoiding poor heat dissipation caused by excessively high air temperature entering the cabinet, improving heat dissipation efficiency in high-temperature environments, and reducing damage to the energy storage battery box from high temperatures.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1: Reference Figure 1-4 The distributed commercial energy storage cabinet shown includes a cabinet 1. Support beams 2 are detachably installed at the four corners of the inner cavity of the cabinet 1. Multiple sets of support platforms 3 are arranged on the support beams 2. Each support platform 3 is equipped with an energy storage battery box 4, which can perform charging and discharging operations. Multiple sets of grooves are opened on the back of the cabinet 1. Extension frames 5 are fixed on the inner wall of the grooves. Multiple flow channels 6 are opened on the surface of the extension frames 5.

[0030] During the use of this distributed commercial energy storage cabinet, under normal power operation and maintenance conditions, the energy storage battery box 4 inside the cabinet 1 can be charged periodically. The energy storage battery box 4 can provide power to the electrical devices in small industrial and commercial sites and can be used as an emergency power supply and backup power supply. The purpose of providing airflow channels 6 is to maintain air circulation between the inside and outside environment of the cabinet 1, which has a certain heat dissipation effect on the energy storage battery box 4.

[0031] The extension rack 5 is protruding, and an air guiding component is provided on the inner side of the extension rack 5 to guide external air into the inside of the cabinet 1. In hot weather, the air temperature guided into the cabinet 1 by the air guiding component is too high, resulting in poor heat dissipation. Therefore, a cooling component is provided on the air guiding component to reduce the temperature of the air entering the cavity of the cabinet 1 from the external environment.

[0032] The air guiding assembly includes a contact plate 7, and a heat insulation plate 8 is provided in front of the contact plate 7. Both the contact plate 7 and the heat insulation plate 8 have through holes 10 on their surfaces.

[0033] The contact plate 7 and the heat insulation plate 8 are connected on opposite sides by multiple connecting pipes 9. Both ends of the connecting pipes 9 are fixed to the inner wall of the through hole 10. In the event of a high-temperature environment, some airflow from the external environment passes through the flow channel 6 and is guided by the contact plate 7 to the inside of the connecting pipes 9 until it passes through the heat insulation plate 8 and enters the inner cavity of the cabinet 1. The airflow flows within the connecting pipes 9 installed inside the through hole 10. Cooling components are installed on the connecting pipes 9 to cool the flowing airflow.

[0034] like Figure 4 , Figure 5 As shown, the air guiding assembly also includes an internal fixed support arm 14 detachably connected to the contact plate 7. An electric control fan 15 is installed at the center of the internal fixed support arm 14. An isolation frame 16 is connected to the surface of the heat insulation plate 8 via a support leg. The isolation frame 16 is located in front of the electric control fan 15.

[0035] When the electric fan 15 is running, it can guide the air outside the cabinet 1, allowing the airflow to quickly pass through the flow channel 6 opened on the extension frame 5, then through the contact plate 7 and the docking pipe 9, and enter the inner cavity of the cabinet 1, accelerating the air circulation between the inside and outside of the cabinet 1, so as to perform heat dissipation work on the energy storage battery box 4.

[0036] The heat insulation board 8 is made of heat-insulating metal, which has a certain barrier effect on the internal and external environment of the cabinet 1. It can effectively prevent the high-temperature airflow outside the cabinet 1 from rushing into the inside of the cabinet 1 without passing through the docking pipe 9.

[0037] Example 2: As Figure 6 , Figure 7 As shown, the cooling component includes a cooling pipe 13, which contains water. The cooling pipe 13 includes multiple covering parts and flow parts. The covering parts have an annular tubular structure and are embedded in the connecting pipes 9. Adjacent covering parts in the horizontal and vertical positions are connected by the flow parts, which have a straight pipe structure. The covering parts and the flow parts are interconnected. After the water enters the cooling pipe 13, it can quickly flow into various parts of the cooling pipe 13 to cover the multiple connecting pipes 9.

[0038] When the airflow enters the docking pipe 9, the low-temperature water inside the cooling pipe 13 can absorb heat and effectively reduce the temperature of the air flowing inside the docking pipe 9. Furthermore, under the guidance of the electric fan 15, the cooled air can quickly enter the cabinet 1 to cool the energy storage battery box 4.

[0039] By incorporating cooling components, the heat dissipation effect of external air entering the cabinet 1 is improved in high-temperature environments. Combined with the operation of the electric fan 15, the heat dissipation efficiency in high-temperature environments is improved, reducing the damage to the energy storage battery box caused by high temperatures.

[0040] like Figure 6 As shown, the surface of the contact plate 7 is provided with multiple arc-shaped guide grooves, and the inner wall of each arc-shaped guide groove is fixed with a first adsorption layer 11. On the flat part of the contact plate 7 near the flow channel 6, multiple second adsorption layers 12 are fixed. The first adsorption layer 11 and the second adsorption layer 12 are arranged alternately. The first adsorption layer 11 is provided with a round hole that matches the through hole 10.

[0041] The purpose of having an arc-shaped guide groove is to guide the incoming airflow. After the incoming airflow passes through the flow channel 6, it can be diverted into the interior of the arc-shaped guide groove under the guiding effect of the bulging second adsorption layer 12, pass through the round hole, enter the interior of the docking pipe 9, and be cooled by the cooling pipe 13. This can guide and cool the air more comprehensively, improve the cooling efficiency, and reduce the phenomenon of air dispersion and loss in the airflow.

[0042] The surfaces of the first adsorption layer 11 and the second adsorption layer 12 are both mesh-like adsorption cotton structures. The first adsorption layer 11 and the second adsorption layer 12 can come into more comprehensive contact with the airflow, effectively adsorbing the dust mixed in the airflow, and purifying the airflow entering the docking pipe 9, thus reducing the accumulation of dust inside the cabinet 1.

[0043] like Figure 6 , Figure 8 As shown, a pair of limiting strips 17 are fixed to the inner wall of the extension frame 5. A docking channel 18, adapted to the limiting strips 17, is opened on the surface of the contact plate 7. When the contact plate 7 is installed in the inner cavity of the extension frame 5, the limiting strips 17 are engaged with the inner side of the docking channel 18. By using a plug-in installation method for the contact plate 7, the contact plate 7, heat insulation plate 8, docking pipe 9, internal fixed support arm 14, electric fan 15, and isolation frame 16 can be simultaneously installed on the inner side of the extension frame 5, improving stability during the docking process. After disassembling the contact plate 7 and the components connected to it, centralized cleaning and maintenance of the components can be performed.

[0044] like Figure 8 , Figure 9 As shown, a pair of positioning rods 19 are fixed to the top of the inner wall of the extension frame 5. An embedded rod 20 is slidably connected to the outer surface of the positioning rod 19. A groove adapted to the embedded rod 20 is opened on the surface of the contact plate 7. When the contact plate 7 is installed in the inner cavity of the extension frame 5, the embedded rod 20 is inserted into the inner wall of the groove. A paddle 21 is fixed on the outer wall of the embedded rod 20.

[0045] The purpose of providing the embedding rod 20 is to facilitate its embedded connection with the inner wall of the groove. Furthermore, it has a locking function for the contact plate 7, preventing the contact plate 7, heat insulation plate 8, connecting pipe 9, and other components connected to the contact plate 7 from falling off during operation, thus improving component stability. The purpose of providing the lever 21 is to facilitate manual operation of the lifting and lowering movement of the embedding rod 20, offering the advantage of portable operation.

[0046] like Figure 7 As shown, a water inlet 22 is provided above the cooling pipe 13. The purpose of providing the water inlet 22 is to facilitate the replacement of the water inside the cooling pipe 13. In hot weather, by replacing the water in the cooling pipe 13, the water can be kept at a stable low temperature, thereby ensuring the cooling efficiency of the cooling pipe 13.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
