Description

Technical Field

[0001] This utility model relates to the field of energy storage cabinet technology, and in particular to an energy storage cabinet for an air-cooled energy storage system. Background Technology

[0002] With the increasingly widespread application of energy storage systems in energy management, energy storage cabinets, as a key component, play a crucial role in ensuring the safe operation of battery packs, extending their service life, and improving overall efficiency. However, existing energy storage cabinet designs, especially in terms of thermal management systems, still have some problems that urgently need to be addressed.

[0003] Current energy storage cabinet air guide plate structures typically use fixed opening sizes to adjust airflow. While this method can guide cold air flow to some extent, its fixed nature makes it difficult to rationally match and freely adjust to different air conditioner installation locations. Because the distance cold air travels within the air ducts varies at different heights, this leads to an imbalance in air resistance between the ducts. Specifically, areas closer to the air inlet may receive more cold airflow, while areas farther from the inlet may experience poor cooling due to reduced airflow velocity. This imbalance not only affects the overall heat dissipation performance of the battery pack but may also lead to localized overheating, thereby shortening battery life and even posing safety hazards. Utility Model Content

[0004] Based on this, in order to solve the problem that the existing energy storage cabinet air guide plate structure cannot regulate the air volume and affects the overall heat dissipation performance of the battery pack, this utility model provides an energy storage cabinet for air-cooled energy storage systems.

[0005] This utility model provides an energy storage cabinet for an air-cooled energy storage system, comprising:

[0006] The cabinet body has a cabinet door on one side and an air guide plate on the other side. The surface of the air guide plate is provided with a partition air duct plate and louvered air vents with independently adjustable openings. Multiple partition air duct plates and louvered air vents are provided, with a partition air duct plate between every two louvered air vents.

[0007] The louvered air vent consists of multiple louvers with adjustable angles.

[0008] Each of the aforementioned louvered air vents has a louver angle adjustment knob on one side for adjusting the louver angle.

[0009] The top and bottom of the cabinet body are both equipped with straight panels.

[0010] A lower air duct plate is provided between the air guide plate and the straight plate at the bottom of the cabinet body. The lower air duct plate and the straight plate at the bottom of the cabinet body form an air outlet duct. An air outlet is provided at the end of the air outlet duct.

[0011] The cabinet body is equipped with a central air intake column, and side air intake columns are provided on both sides of the central air intake column. The two side air intake columns are symmetrically arranged about the central air intake column.

[0012] Multiple racks for installing battery packs are provided on both sides of the central air intake column, and multiple racks for installing battery packs are also provided on the side of the side air intake column near the central air intake column.

[0013] The cabinet body is equipped with multiple support feet at the bottom.

[0014] Beneficial effects: By setting multiple partition air ducts and louvered air vents on the air guide plate, the partition air ducts and louvered air vents can evenly distribute the airflow to all parts of the cabinet, avoid local overheating, and improve the heat dissipation effect.

[0015] Each louvered air outlet can be independently adjusted to allow for airflow adjustment according to actual needs, ensuring that heat dissipation efficiency matches system requirements.

[0016] The partition panels make the air ducts independent, avoiding mutual interference of the incoming air; the independently adjustable louvered air vents can adjust the air resistance of the air ducts at different heights inside the energy storage cabinet.

Detailed Implementation

[0025] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of the present invention, including various details to aid understanding. These embodiments should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0026] like Figures 1 to 5 As shown, this utility model provides an energy storage cabinet for an air-cooled energy storage system, comprising:

[0027] The counter body 1 has a cabinet door 23 on one side and an air guide plate 22 on the other side. The surface of the air guide plate 22 is provided with a partition air duct plate 31 and a louvered air vent 32 with an independently adjustable opening. Multiple partition air duct plates 31 and multiple louvered air vents 32 are provided, and a partition plate is provided between every two louvered air vents 32.

[0028] Preferably, this utility model provides multiple partition air duct plates 31 and louvered air vents 32 on the air guide plate 22. The partition air duct plates 31 and louvered air vents 32 can evenly distribute airflow to all parts of the cabinet, avoid local overheating, and improve the heat dissipation effect.

[0029] Each 32 louvered air vent can be independently adjusted to allow for easy adjustment of airflow according to actual needs, ensuring that heat dissipation efficiency matches system requirements.

[0030] The partition plate 31 separates the air ducts, preventing mutual interference between incoming air. The independently adjustable louvered air vents 32 can adjust the air resistance of the air ducts at different heights within the energy storage cabinet, precisely controlling the airflow of each duct. The technical solution proposed in this invention comprehensively considers airflow distribution and air resistance. In addition to controlling airflow balance, it can also increase or decrease the airflow of different air ducts according to the actual temperature changes of the battery cells, further improving the overall performance of the energy storage cabinet. This invention can flexibly adjust the area of ​​the louvered air vents 32 according to different energy storage cabinet structures and air duct conditions, exhibiting strong adaptability and being suitable for various types of air-cooled energy storage cabinets.

[0031] The partition plate 31 can prevent airflow from passing directly through, ensuring that cold air fully contacts the equipment before being discharged, thus improving heat dissipation efficiency.

[0032] The louvered air vent 32 is composed of multiple louvers with adjustable angles.

[0033] Each of the louvered air vents 32 is provided with a louver angle adjustment knob 33 on one side for adjusting the louver angle.

[0034] By adjusting the louver angle, a uniform airflow distribution can be achieved, avoiding problems such as localized overheating or uneven heat dissipation.

[0035] The counter body 1 is provided with straight panels 11 at both the top and bottom.

[0036] A lower air duct plate 27 is provided between the air guide plate 22 and the straight plate 11 at the bottom of the counter body 1. The lower air duct plate 27 and the straight plate 11 at the bottom of the counter body 1 form an air outlet duct. An air outlet 21 is provided at the end of the air outlet duct.

[0037] The lower side of the energy storage cabinet is provided with a lower air duct plate 27. The lower air duct plate 27 and the straight plate 11 at the bottom of the cabinet body 1 form an air outlet duct. Cold air flows into the air conditioner from the air outlet 21 through the air outlet duct and completes the circulation.

[0038] The louver angle adjustment knob 33 design makes adjusting the louver angle more convenient and quick, without the need for complicated tools or disassembly, making it easy for daily maintenance and operation.

[0039] Preferably, the louver angle adjustment knob 33 can be a gear, and a gear is also provided at one end of each louver. One side of the rack meshes with the louver angle adjustment knob 33, and the gear at the end of the louver meshes with the other side of the rack. When it is necessary to adjust the louver angle, the louver angle adjustment knob 33 can be rotated to adjust the angle of the louver.

[0040] Because the air guide plate 22 is equipped with a partition air duct plate 31, the mutual interference of the cold air entering the battery pack at the air inlet is avoided.

[0041] Rotating the louver angle adjustment knob 33 changes the louver angle via gear transmission, thereby altering the air inlet area. This allows for independent adjustment of the airflow resistance in each duct. Through calculations and simulations in fluid mechanics, the airflow distribution ratio for each duct is determined. Adjusting the louvered air outlets 32 of the air guide plate 22 according to this ratio improves airflow regulation, further enhancing the temperature uniformity of the battery cells within the cabinet and improving the overall performance of the air-cooled energy storage cabinet. Optimizing airflow direction reduces unnecessary airflow waste, lowers fan energy consumption, and improves the overall system energy efficiency.

[0042] The counter body 1 is equipped with a central air intake column 24, and side air intake columns 25 are provided on both sides of the central air intake column 24. The two side air intake columns 25 are symmetrically arranged about the central air intake column 24.

[0043] Multiple battery pack mounting racks 26 are provided on both sides of the central air intake column 24, and multiple battery pack mounting racks 26 are also provided on the side of the side air intake column 25 near the central air intake column 24.

[0044] Cold air flows out from the air conditioning vent and enters the energy storage cabinet through the air guide plate 22. Then, some of the cold air enters the battery pack directly from the vent on one side of the battery pack, while some of the cold air enters the vents on both sides of the battery pack through the side air intake column 25 and the middle air intake column 24. After heat exchange, the cold air flows out from the vent on the other side of the battery pack and converges downwards to the air outlet 21.

[0045] The bottom of the counter body 1 is provided with multiple support legs 12.

[0046] The support feet 12 can stably support the energy storage cabinet body, prevent it from tilting or shaking, and ensure that the energy storage cabinet remains stable during operation or movement.

[0047] Support feet 12 lift the energy storage cabinet off the ground, creating a gap between the bottom of the cabinet and the ground, which facilitates air circulation, prevents heat from accumulating at the bottom of the cabinet, and improves the overall heat dissipation effect.

[0048] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
