Description

Technical Field

[0001] This utility model relates to the field of energy storage cabinets, and more particularly to a discrete energy storage system. Background Technology

[0002] Because the output power of wind turbine generators is greatly affected by on-site wind conditions, its power output is unstable, resulting in energy waste. Battery energy storage, with its advantages of wide applicability, fast frequency response, and high energy density, has become the mainstream trend.

[0003] A discrete energy storage cabinet is an energy storage device consisting of components such as a battery pack, inverter, charge / discharge controller, and communication controller, all independently housed within a cabinet and connected by cables to form a system. Its working principle is primarily based on electrochemical energy storage technology. During charging, electrical energy is converted into chemical energy by the battery management system and stored in the battery pack. During discharging, the chemical energy is converted back into electrical energy, which is then converted into alternating current (AC) or direct current (DC) by the inverter to supply power to the load. Discrete energy storage cabinets can draw and store electrical energy from the grid or other renewable energy generation equipment when grid demand is low. When grid demand is high, the cabinet can convert the stored electrical energy into AC power output via a DC / AC converter to support the grid.

[0004] Chinese Patent Publication No. CN220896081U discloses a discrete energy storage cabinet, including a battery box. The battery box is connected to a control compartment at its bottom, and the battery box houses a battery pack. The control compartment houses a control box. One side of the battery box is connected to an electrical compartment, which houses electrical components. A cover plate connects the battery box and the electrical compartment to the top. This discrete energy storage cabinet integrates the battery box, control compartment, and electrical compartment into a single unit, allowing for better space utilization. The cabinet design can be optimized as needed, ensuring a compact layout between devices, thus reducing floor space. Exposed cables enhance safety. The integrated devices provide more convenient maintenance and management; maintenance personnel can access the devices by opening the cabinet door to perform necessary inspections and maintenance, simplifying the maintenance process, reducing maintenance time, and improving equipment reliability.

[0005] In actual operation, existing discrete energy storage cabinets utilize built-in fan systems to dissipate heat from battery packs and other electronic components to ensure normal operation and extend service life. However, the heat dissipation vents of existing energy storage cabinets are usually located in fixed positions, which means that cold air can only flow out from specific vents, thus limiting the airflow range. This makes it difficult to achieve uniform heat dissipation for battery packs or other electronic components, which not only reduces the overall operating efficiency of the energy storage cabinet but may also accelerate the aging of battery packs and shorten their service life, resulting in a lack of heat dissipation efficiency in discrete energy storage cabinets. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a discrete energy storage cabinet with uniform heat dissipation.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a discrete energy storage cabinet, comprising:

[0008] Hollow core board divides the cabinet interior into a first chamber and a second chamber. The side wall of the hollow core board near the second chamber has three or more through holes.

[0009] A partition is installed between two adjacent through holes, dividing the second chamber into a fan compartment and two or more electrical compartments. The fan compartment is equipped with a cooling fan.

[0010] The cabinet's wall panels are equipped with air inlets and outlets corresponding to the fan compartment and electrical compartment, respectively.

[0011] Furthermore, the through-hole includes an air inlet and an air outlet. The air inlet is connected to the fan compartment, and the air outlet is connected to the electrical compartment.

[0012] Furthermore, the partition includes a support plate and a partition plate. The support plate is installed between the air inlet and the air outlet. The fan compartment and the electrical compartment are separated independently by the support plate, and the partition plate is installed between two adjacent air outlets.

[0013] Furthermore, the support plate is provided with a support rod, the support rod is provided with a first support groove, the hollow plate is provided with a second support groove, and the partition plate is respectively engaged with the first support groove and the second support groove.

[0014] Furthermore, the side walls of the cabinet are provided with a first cabinet door and a second cabinet door in sequence, corresponding to the first chamber and the second chamber.

[0015] Furthermore, it also includes a cleaning component, one end of which is movably connected to the second cabinet door, and the other end of which slides within the air outlet.

[0016] Furthermore, the cleaning component includes an abutment rod, with an abutment wheel and a drive plate at each end of the abutment rod. The drive plate has a cleaning plate that is slidably connected to the air outlet. The cabinet has a fixed plate with a guide rod that is slidably connected to the drive plate. A spring is sleeved on the guide rod, and the spring abuts against the fixed plate and the drive plate respectively. The second cabinet door has a limiting plate with a slope that supports the abutment wheel.

[0017] Furthermore, the first cabinet door is equipped with ventilation holes.

[0018] Furthermore, a filter plate is installed inside the air inlet.

[0019] Furthermore, the air outlet is angled outwards and downwards from inside the cabinet.

[0020] The beneficial effects of this utility model are as follows: A discrete energy storage cabinet, through the cavity opened inside the support plate and multiple through holes on one side, can ensure that cold air is uniformly and stably introduced into the discrete energy storage cabinet, thereby efficiently and evenly blowing onto the surface of the battery pack and other key electronic components, achieving a deep and comprehensive heat dissipation effect.

This optimizes the overall performance of the discrete energy storage cabinet, extends the service life of the battery pack and electronic components, and makes the heat dissipation effect of the discrete energy storage cabinet better.

[0027] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0028] Please refer to Figures 1 to 4 As shown, a discrete energy storage cabinet of this utility model includes:

[0029] Hollow board 2 divides the inner cavity of cabinet 1 into a first chamber and a second chamber. Hollow board 2 has three or more through holes on the side wall near the second chamber.

[0030] A partition is installed between two adjacent through holes, dividing the second chamber into a fan compartment and two or more electrical compartments. The fan compartment is equipped with a cooling fan 7.

[0031] The wall panels of cabinet 1 are provided with air inlets and air outlets 21 in sequence, corresponding to the fan compartment and the electrical compartment.

[0032] As can be seen from the above description, the beneficial effects of this utility model are as follows: A discrete energy storage cabinet, through the cavity opened inside the support plate and multiple through holes on one side, can ensure that cold air is uniformly and stably introduced into the discrete energy storage cabinet, thereby efficiently and evenly blowing onto the surface of the battery pack and other key electronic components, achieving a deep and comprehensive heat dissipation effect. This not only significantly improves the heat dissipation efficiency, allowing the heat inside the energy storage cabinet to be removed more quickly, but also ensures the uniformity of the heat dissipation effect, avoiding the occurrence of local overheating, thereby optimizing the overall performance of the discrete energy storage cabinet, extending the service life of the battery pack and electronic components, and making the heat dissipation effect of the discrete energy storage cabinet better.

[0033] In an optional embodiment, the through hole includes an air inlet 11 and an air outlet 12, with the air inlet 11 connected to the fan compartment and the air outlet 12 connected to the electrical compartment.

[0034] In an optional embodiment, the partition includes a support plate 6 and a partition plate 8. The support plate 6 is installed between the air inlet 11 and the air outlet 12. The fan compartment and the electrical compartment are separated independently by the support plate 6. The partition plate 8 is installed between two adjacent air outlets 12.

[0035] As described above, in order to evenly dissipate heat from the battery packs or other electronic components inside the discrete energy storage cabinet, an air inlet 11 is provided through one side of the fan compartment at the bottom of the support plate 6, and multiple air outlets 12 are provided through one side of the electrical compartment at the top of the support plate 6. The cavity inside the hollow plate 2 allows the cool air blown out by the cooling fan 7 to evenly enter the cabinet 1 through the multiple air outlets 12, which not only significantly improves the heat dissipation efficiency, allowing the heat inside the cabinet 1 to be carried away more quickly, but also ensures the uniformity of the heat dissipation effect and avoids the occurrence of local overheating.

[0036] In an optional embodiment, the support plate 6 is provided with a support rod 13, the support rod 13 is provided with a first support groove, the hollow plate 2 is provided with a second support groove, and the partition plate 8 is respectively engaged with the first support groove and the second support groove.

[0037] As can be seen from the above description, the positions of multiple partition plates 8 can be flexibly adjusted by multiple first support grooves on one side of the hollow plate 2 and multiple second support grooves on one side of multiple support rods 13, so as to adapt to battery packs of different sizes and specifications.

[0038] In an optional embodiment, the side wall of the cabinet 1 is provided with a first cabinet door 3 and a second cabinet door 5 in sequence corresponding to the first chamber and the second chamber.

[0039] In an optional embodiment, a cleaning component is also included, one end of which is movably connected to the second cabinet door 5, and the other end of which slides within the air outlet 21.

[0040] As can be seen from the above description, in order to conveniently clean the impurities in the air outlet 21, a cleaning component is designed to clean the air outlet 21 by opening or closing the second cabinet door 5.

[0041] In an optional embodiment, the cleaning component includes an abutment rod 17, with an abutment wheel 18 and a drive plate 9 at each end of the abutment rod 17. The drive plate 9 has a cleaning plate 20 that is slidably connected to the air outlet 21. The cabinet 1 has a fixing plate 14, with a guide rod 15 on the fixing plate 14. The guide rod 15 is slidably connected to the drive plate 9. A spring 16 is sleeved on the guide rod 15, and the spring 16 abuts against the fixing plate 14 and the drive plate 9 respectively. The second cabinet door 5 has a limiting plate 19, which has a slope that supports the abutment wheel 18.

[0042] As can be seen from the above description, by using the abutment rod 17 and abutment wheel 18 set on one side of the drive plate 9, and in conjunction with the limiting plate 19 on one side of the second cabinet door 5, the cleaning plates 20 located inside the multiple air outlets 21 can be moved synchronously when the second cabinet door 5 is opened or closed. This not only greatly simplifies the process of cleaning impurities inside the air outlets 21, allowing operators to easily and thoroughly clean the inside of the air outlets 21, but also ensures that the air outlets 21 can remain unobstructed, effectively avoiding the adverse effects of dust, fibers and other impurities on heat dissipation.

[0043] Multiple guide rods 15 on one side of the fixed plate 14 restrict the movement of the drive plate 9, preventing it from shifting position during movement. A spring 16 can drive the drive plate 9 back to its original position. By using a sloped surface, in conjunction with a rotatable abutment wheel 18 at one end of the abutment rod 17, the drive plate 9 can be moved when the second cabinet door 5 is closed. When the drive plate 9 moves, it simultaneously moves multiple cleaning plates 20, thus conveniently and effectively cleaning impurities from multiple air outlets 21. This not only greatly simplifies the cleaning process of the air outlets 21 but also ensures that the air outlets 21 remain unobstructed, effectively preventing impurities from negatively impacting heat dissipation.

[0044] In an optional embodiment, the first cabinet door 3 is provided with heat dissipation holes 4.

[0045] In an optional embodiment, a filter plate 10 is provided inside the air inlet.

[0046] As can be seen from the above description, the filter plate 10 can filter impurities in the air drawn in by the cooling fan 7, so as to prevent impurities from damaging the battery pack or other electronic components inside the cabinet 1.

[0047] In an optional embodiment, the air outlet 21 is inclined outward and downward from the inside of the cabinet 1.

[0048] Please refer to Figures 1 to 4 As shown, Embodiment 1 of this utility model is: a discrete energy storage cabinet, comprising:

[0049] The cabinet 1 has a hollow panel 2 inside; a first cabinet door 3 is located on one side of the cabinet 1, and the first cabinet door 3 has a heat dissipation hole 4. The other side of the same side has a second cabinet door 5; a support plate 6 is located at the bottom of the second chamber inside the cabinet 1, and one end of the support plate 6 is installed on the side wall of the hollow panel 2. A cooling fan 7 is installed in the fan compartment below the support plate 6; a partition plate 8 is also located in the second chamber on one side of the hollow panel 2. Multiple air outlets 21 are provided through one side of the cabinet 1. The multiple air outlets 21 are all inclined. A drive plate 9 is provided inside the cabinet 1 on one side of the multiple air outlets 21.

[0050] An air inlet is provided through the bottom of the cabinet 1 located at the bottom of the cooling fan 7, and a filter plate 10 is provided inside the air inlet.

[0051] The hollow board 2 has a cavity, and an air inlet 11 is provided through one side of the cavity at the bottom of the support plate 6. Multiple air outlets 12 are provided through one side of the cavity at the top of the support plate 6.

[0052] Multiple support rods 13 are provided on one side of the upper end of the bearing plate 6. Multiple first support grooves adapted to the partition plate 8 are provided on one side of each of the multiple support rods 13. Multiple second support grooves are provided on the side wall of the hollow plate 2. The two ends of the multiple partition plates 8 are respectively located in the multiple first support grooves and the multiple second support grooves.

[0053] The inner wall of the cabinet 1 is provided with a fixing plate 14, and a plurality of guide rods 15 are provided on one side of the fixing plate 14. The drive plate 9 is provided with a plurality of guide holes that are adapted to the guide rods 15. The plurality of guide rods 15 pass through the plurality of guide holes respectively and are slidably connected to the side wall of the guide hole.

[0054] Multiple guide rods 15 are fitted with springs 16 on their outer sides, with the two ends of the springs 16 positioned between the fixed plate 14 and the drive plate 9.

[0055] A contact rod 17 is provided on one side of the drive plate 9, and a contact wheel 18 is rotatably connected to one end of the contact rod 17. A limiting plate 19 is provided on one side of the second cabinet door 5. The limiting plate 19 has an inclined slope, and one end of the contact wheel 18 abuts against the inclined slope. A plurality of cleaning plates 20 adapted to the air outlet 21 are provided on one side of the drive plate 9. The plurality of cleaning plates 20 are respectively located in the plurality of air outlets 21 and are slidably connected to the side wall of the air outlet 21.

[0056] The working principle of this embodiment is as follows: When using a discrete energy storage cabinet, the battery pack or other electronic components inside the cabinet will generate a lot of heat after a long period of use, requiring air cooling. During the cooling process, the cooling fan 7 needs to be activated. The cooling fan 7 will blow cold air into the cavity inside the hollow plate 2 through the air inlet 11. The cold air will be blown evenly onto the battery pack or other electronic components through multiple air outlets 12 on one side of the cavity. This not only significantly improves the heat dissipation efficiency, allowing the heat inside the cabinet 1 to be carried away more quickly, but also ensures the uniformity of the heat dissipation effect, avoiding the occurrence of local overheating, and making the heat dissipation efficiency of the discrete energy storage cabinet better.

[0057] In summary, the discrete energy storage cabinet of this utility model, through the cavity opened inside the support plate and the multiple through holes on one side, can ensure that cold air is uniformly and stably introduced into the discrete energy storage cabinet, thereby efficiently and evenly blowing onto the surface of the battery pack and other key electronic components, achieving a deep and comprehensive heat dissipation effect. This not only significantly improves the heat dissipation efficiency, allowing the heat inside the energy storage cabinet to be removed more quickly, but also ensures the uniformity of the heat dissipation effect, avoiding the occurrence of local overheating. Thus, it optimizes the overall performance of the discrete energy storage cabinet, extends the service life of the battery pack and electronic components, and makes the heat dissipation effect of the discrete energy storage cabinet better.
