Description

Technical Field

[0001] This utility model relates to the field of energy storage cabinet technology, specifically to an improved upper and lower structure of an energy storage cabinet. Background Technology

[0002] An energy storage cabinet is a device capable of storing electrical energy, typically composed of battery packs, inverters, and control chips. It has the function of storing electrical energy and releasing it for power supply when needed, primarily used to provide backup power and stabilize grid voltage. Energy storage cabinets play a vital role in modern society, especially in the renewable energy sector. They can smooth out fluctuations caused by the integration of non-connected renewable energy sources into the grid, maintain grid stability, suppress load fluctuations, and perform frequency and voltage regulation, thereby improving the power factor. Furthermore, data center energy storage cabinets primarily provide reliable backup power and energy regulation for data centers to cope with power outages or peak energy demand, ensuring the continuity, reliability, and energy efficiency of the data center.

[0003] Existing technology, such as the patent with publication number CN220731680U, discloses a power storage equipment cabinet with good heat dissipation, including a cabinet body and energy storage units. A partition plate is installed inside the cabinet, and four mounting brackets are installed on the partition plate in a rectangular shape. Several support plates are installed between the four mounting brackets from top to bottom. This utility model dissipates heat from the power storage equipment cabinet by combining air cooling and water cooling. Compared with existing single heat dissipation methods, this utility model uses a combination of two cooling methods, resulting in better heat dissipation and higher efficiency. By opening air inlets on all four sides of the cabinet body, fresh air can enter the power storage equipment cabinet from different directions, making heat dissipation in different areas of the power storage equipment cabinet more balanced and ensuring overall heat dissipation. Furthermore, dust baffles are installed inside the air inlets to effectively prevent dust from entering the power storage equipment cabinet, ensuring the safety of the equipment inside.

[0004] Existing technologies still have shortcomings:

[0005] The existing technologies described above use air cooling and water cooling to dissipate heat inside the energy storage cabinet. However, in actual use, while dissipating heat, external dust also enters the energy storage cabinet, causing dust to adhere to the energy storage units inside the cabinet, which in turn affects the heat dissipation of the energy storage units. At the same time, it is difficult to dissipate heat evenly to the energy storage units inside the cabinet, resulting in excessive temperature differences in the working environment of each energy storage unit, which affects the cycle life of the battery cells. Therefore, an improved upper and lower structure for the energy storage cabinet is proposed. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an improved upper and lower structure for energy storage cabinets, which facilitates heat dissipation and improves the uniformity of heat dissipation.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an improved upper and lower structure for an energy storage cabinet, comprising an energy storage cabinet body, an air inlet chamber at the lower end of the energy storage cabinet body, a chiller installed on one side of the energy storage cabinet body, the output end of the chiller communicating with the interior of the air inlet chamber, two channel partitions fixed inside the energy storage cabinet body, a partition plate fixedly connected between the two channel partitions, a first air inlet group and a second air inlet group respectively located above and below the partition plate on the side wall of the channel partition, two sets of air delivery holes on the top wall of the air inlet chamber, the air delivery holes communicating with the space between the internal side wall of the energy storage cabinet body and the adjacent channel partition, and an upper opening door and a lower opening door hinged on one side of the energy storage cabinet body, the upper opening door and the lower opening door respectively blocking the space above and below the partition plate.

[0008] Preferably, the partition plate has an L-shaped structure, and an independent cold air channel is formed between the partition plate and the internal side wall of the adjacent energy storage cabinet.

[0009] Preferably, the partition plate has a hollow cavity structure inside, a first exhaust groove is provided on the bottom surface of the partition plate, an exhaust cavity is provided at the upper end of the energy storage cabinet body, a second exhaust groove is provided on the bottom surface of the exhaust cavity, and two exhaust hoods are installed on the back side of the energy storage cabinet body, which are respectively connected to the interior of the partition plate and the interior of the exhaust cavity.

[0010] Preferably, the two exhaust hoods are interconnected by a pipe, and one of the exhaust hoods is connected to the air inlet of the refrigeration unit by a pipe.

[0011] Preferably, a partition frame is fixedly connected to the inner bottom surface of the energy storage cabinet body. The partition frame is located between the channel partition and the inner side wall of the adjacent energy storage cabinet body. The upper end of the partition frame is fixedly connected to the side wall of the channel partition. The fixed connection between the partition frame and the channel partition is located at the first air inlet group and the second air inlet group. The air delivery port includes a first delivery port and a second output port. The partition frame is located between the first delivery port and the second output port.

[0012] Preferably, two sliding openings are provided on both sides of the main body of the energy storage cabinet. One of the sliding openings on the side wall of the main body of the energy storage cabinet is located between the partition frame and the first air inlet group, and the other sliding opening is connected to the air inlet cavity. A baffle plate is slidably connected inside the sliding opening. The baffle plate located below is in contact with the inner top wall of the air inlet cavity, and the upper surface of the baffle plate is provided with multiple clearance holes, which correspond to the first conveying hole.

[0013] Preferably, two threaded rods are rotatably connected to both sides of the main body of the energy storage cabinet. A throttle is fixedly connected to one end of the threaded rod, and a threaded block is threadedly connected to the outer wall of the threaded rod. The threaded block is fixedly connected to the bottom surface of the adjacent baffle plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model divides the interior of the energy storage cabinet by installing two channel partitions and a dividing plate inside the main body of the energy storage cabinet. Then, energy storage units and power distribution controllers are installed in the divided spaces respectively. A chiller is used to deliver cold air between the dividing plate and the inner wall of the energy storage cabinet.

[0016] 2. The cold air entering the space above and below the partition plate of this utility model cools the interior of the energy storage cabinet and drives the heat inside the energy storage cabinet to enter the air inlet of the refrigeration unit through the exhaust hood. The heat is then cooled by the refrigeration unit and enters the energy storage cabinet, causing air to circulate inside the energy storage cabinet and improving the heat dissipation effect.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6 The improved upper and lower structure of the energy storage cabinet in this embodiment includes an energy storage cabinet body 1. An air inlet chamber 2 is provided at the lower end of the energy storage cabinet body 1. A chiller 4 is installed on one side of the energy storage cabinet body 1. The output end of the chiller 4 is connected to the interior of the air inlet chamber 2. Two channel partitions 5 are fixed inside the energy storage cabinet body 1. A partition plate 6 is fixedly connected between the two channel partitions 5. A first air inlet group 7 and a second air inlet group 8 are provided on the side wall of the channel partition 5, respectively located above and below the partition plate 6. Two sets of air delivery holes 9 are provided on the top wall of the air inlet chamber 2. The air delivery holes 9 are connected to the space between the internal side wall of the energy storage cabinet body 1 and the adjacent channel partitions 5. An upper opening door 10 and a lower opening door 11 are hinged on one side of the energy storage cabinet body 1. The upper opening door 10 and the lower opening door 11 respectively block the space above and below the partition plate 6.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the improved upper and lower structure of the energy storage cabinet in this utility model is similar to the improved upper and lower structure of existing energy storage cabinets, such as the prior art CN220731680U. The main improvement of this utility model is to facilitate heat dissipation of the energy storage cabinet and improve the uniformity of heat dissipation. In this utility model, the internal space of the main body 1 of the energy storage cabinet is divided into upper and lower parts by two channel partitions 5 and partition plates 6. The energy unit is installed in the upper part of the space, and the power distribution controller used to control and protect the energy unit is installed in the lower part of the space. When the energy unit and the power distribution controller are working, the chiller 4 is started to work, cooling the system. The chiller 4 delivers cold air into the air inlet chamber 2. The cold air is then delivered through the air delivery holes 9 on the top wall of the air inlet chamber 2 to the space between the channel partition 5 and the inner wall of the adjacent energy storage cabinet body 1. The cold air then enters the space above and below the partition 6 from the first air inlet group 7 and the second air inlet group 8, respectively, thereby dissipating heat from the energy unit and the power distribution controller. The cold air is dispersed through the first air inlet group 7 and the second air inlet group 8, improving the uniformity of heat dissipation for the energy unit and the power distribution controller. The chiller 4 delivers cold air directly into the energy storage cabinet body 1, preventing dust from entering the energy storage cabinet body 1 and affecting heat dissipation, thus improving the heat dissipation effect.

[0028] The refrigeration unit 4 mentioned above can be purchased from the market. It is a mature technology that has been fully disclosed, so it will not be repeated in the instruction manual. The refrigeration unit 4 is equipped with a power connection cable, and it is electrically connected to the external main controller and 220V phase voltage (or 380V line voltage) through the power connection cable. The main controller can be a conventional known device such as a computer that plays a control role.

[0029] like Figures 2-4 As shown, the partition plate 6 has an L-shaped structure, and the partition plate 6 forms an independent cold air channel with the internal side wall of the adjacent energy storage cabinet body 1. When the cabinet door of the energy storage cabinet body 1 is opened, the cold air conveyed upward from the air conveying hole 9 can only be discharged from the first air inlet group 7 and the second air inlet group 8, thus avoiding the overflow and waste of cold air.

[0030] like Figure 3 , Figure 4 and Figure 6 As shown, the partition plate 6 has a hollow cavity structure. A first exhaust groove 13 is provided on the bottom surface of the partition plate 6, and an exhaust cavity 3 is provided at the upper end of the energy storage cabinet body 1. A second exhaust groove 14 is provided on the bottom surface of the exhaust cavity 3. Two exhaust hoods 15 are installed on the back side of the energy storage cabinet body 1, which are respectively connected to the interior of the partition plate 6 and the interior of the exhaust cavity 3. The cold air entering the space above and below the partition plate 6 dissipates heat from the energy unit and the power distribution controller. The heat generated by the energy unit is transferred from the second exhaust groove 14 to the exhaust cavity 3 and discharged through the exhaust hood 15. The heat generated by the power distribution controller enters the interior of the partition plate 6 from the first exhaust groove 13 and is discharged through the exhaust hood 15, thereby causing the air inside the energy storage cabinet body 1 to circulate and improving the heat dissipation effect.

[0031] like Figure 3 , Figure 4 and Figure 6 As shown, the two exhaust hoods 15 are interconnected by pipes, and one of the exhaust hoods 15 is connected to the air inlet of the chiller 4 through a pipe. The chiller 4, in conjunction with the exhaust hoods 15, extracts the heat entering the exhaust cavity 3 and the partition plate 6 through the pipes, thereby extracting the heat inside the energy storage cabinet body 1, improving the heat dissipation effect inside the energy storage cabinet body 1. After the heat enters the chiller 4, the chiller 4 cools the heat and then re-transports it into the energy storage cabinet body 1, thereby enabling the chiller 4 to circulate the air inside the energy storage cabinet body 1, preventing external dust from entering the energy storage cabinet body 1.

[0032] like Figure 3As shown, a partition frame 12 is fixedly connected to the bottom surface of the energy storage cabinet body 1. The partition frame 12 is located between the channel partition 5 and the adjacent internal side wall of the energy storage cabinet body 1. The upper end of the partition frame 12 is fixedly connected to the side wall of the channel partition 5. The fixed connection between the partition frame 12 and the channel partition 5 is located at the first air inlet group 7 and the second air inlet group 8. The air conveying hole 9 includes a first conveying hole 91 and a second output hole 92. The partition frame 12 is located between the first conveying hole 91 and the second output hole 92. The cold air conveyed upward from the air conveying hole 9 is partly conveyed from the first conveying hole 91 to the space between the partition frame 12 and the energy storage cabinet body 1 and output through the first air inlet group 7. The other part is conveyed from the second conveying hole 92 to the space between the partition frame 12 and the channel partition 5 and output through the second air inlet group 8. The cold air is diverted to ensure that the space above and below the partition 6 can receive an appropriate amount of cold air for heat dissipation, thereby improving practicality.

[0033] like Figures 3-5 As shown, two sliding openings 16 are provided on both sides of the energy storage cabinet body 1. One of the sliding openings 16 located on the side wall of the energy storage cabinet body 1 is between the partition frame 12 and the first air inlet group 7, and the other sliding opening 16 is connected to the air inlet cavity 2. A baffle plate 20 is slidably connected inside the sliding opening 16. The lower baffle plate 20 is in contact with the inner top wall of the air inlet cavity 2, and the upper surface of the baffle plate 20 is provided with multiple clearance holes 21, which correspond to the first conveying hole 91. When it is necessary to open the space above the partition plate 6 inside the energy storage cabinet body 1, the two baffle plates 20 located on the upper sides of the energy storage cabinet body 1 are pushed into the energy storage cabinet body 1 along the sliding opening 16, so that the baffle plate 20 blocks the space above the partition frame 12 and is located below the first air inlet group 7, thereby allowing the baffle plate 20 to allow the rising cold air to enter. The obstruction prevents cold air from moving to the first air inlet group 7 and being delivered to the space above the partition plate 6. At this time, the upper opening door 10 above the energy storage cabinet body 1 can be opened. If it is necessary to open the space below the partition plate 6 inside the energy storage cabinet body 1, the two baffles 20 located on the lower sides of the energy storage cabinet body 1 are pushed into the air inlet cavity 2 along the sliding opening 16. The clearance hole 21 on the baffle 20 is connected to the first conveying hole 91 and the second conveying hole 92 is blocked. This allows the cold air to be delivered and rise through the clearance hole 21 from the first conveying hole 91 and be discharged from the first air inlet group 7. The cold air cannot enter between the partition frame 12 and the channel partition 5 and be discharged from the second air inlet group 8 to the space below the partition plate 6 inside the energy storage cabinet body 1. At this time, the lower opening door 11 below the energy storage cabinet body 1 can be opened to reduce the waste of cold air.

[0034] like Figure 5As shown, two threaded rods 17 are rotatably connected to both sides of the main body 1 of the energy storage cabinet. A handle 18 is fixedly connected to one end of the threaded rod 17. A threaded block 19 is threadedly connected to the outer wall of the threaded rod 17. The threaded block 19 is fixedly connected to the bottom surface of the adjacent baffle plate 20. When the handle 18 is gripped, the handle 18 drives the threaded rod 17 to rotate. The threaded rod 17 drives the threaded block 19 on its outer wall to move the baffle plate 20. The baffle plate 20 slides in the sliding opening 16, which facilitates the control and limitation of the position of the baffle plate 20 and improves its practicality.

[0035] In this embodiment, the internal space of the energy storage cabinet body 1 is divided into upper and lower parts by two channel partitions 5 and partition plates 6. The energy unit is installed in the upper part of the space, and the power distribution controller used to control and protect the energy unit is installed in the lower part of the space. When the energy unit and the power distribution controller are working, the chiller 4 is started. The chiller 4 delivers cold air to the air inlet chamber 2. The cold air is delivered through the air delivery holes 9 on the top wall of the air inlet chamber 2 to the space between the channel partition 5 and the inner wall of the adjacent energy storage cabinet body 1. The cold air then enters the space above and below the partition plate 6 from the first air inlet group 7 and the second air inlet group 8, respectively. The cool air in the space dissipates heat from the energy unit and the power distribution controller. The heat generated by the energy unit is transported from the second exhaust duct 14 to the exhaust cavity 3 and discharged through the exhaust hood 15. The heat generated by the power distribution controller enters the partition plate 6 from the first exhaust duct 13. The chiller 4 extracts the heat entering the exhaust cavity 3 and the partition plate 6 through the pipes and in conjunction with the exhaust hood 15, thereby extracting the heat inside the energy storage cabinet body 1, improving the heat dissipation effect inside the energy storage cabinet body 1. After the heat enters the chiller 4, the chiller 4 cools the heat and then transports it back into the energy storage cabinet body 1, thereby enabling the chiller 4 to circulate the air inside the energy storage cabinet body 1.

[0036] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
