Description

Technical Field

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

[0002] Against the backdrop of global energy transition and rapid development of renewable energy, energy storage systems, as a core component for stable power supply and peak shaving, are becoming increasingly critical in terms of safety and reliability. Air-cooled energy storage cabinets, with their advantages of low cost and convenient maintenance, have become one of the mainstream choices for small and medium-sized energy storage scenarios. However, with the increase in energy storage density and battery capacity, the heat dissipation efficiency and structural stability issues of traditional air-cooled energy storage cabinets are becoming increasingly prominent, urgently requiring technological innovation to achieve performance breakthroughs.

[0003] Existing air-cooled energy storage cabinets typically employ a single air conditioning supply structure. Cooling airflow enters the internal space directly through the cabinet's air inlet, relying on natural convection or simple deflectors for airflow distribution. The underlying technology relies on airflow carrying away the heat generated by the battery modules, with air conditioning maintaining a balanced temperature within the cabinet. However, this system suffers from a relatively crude airflow path design, lacking sophisticated guiding components, making it difficult for airflow to cover all areas inside the energy storage cabinet.

[0004] However, existing energy storage cabinets lack a scientific airflow guidance system, making it difficult for cooling air to effectively penetrate the gaps between battery modules. This results in some battery modules being in a high-temperature environment for extended periods, which not only reduces battery charging and discharging efficiency but also accelerates battery aging, seriously affecting the lifespan and operational safety of the energy storage system and making it difficult to meet the heat dissipation requirements of high-power, high-density energy storage scenarios. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an improved air-cooled energy storage cabinet, which aims to improve the problem that existing energy storage cabinets lack a scientific airflow guidance system, making it difficult for cooling air to effectively penetrate the gaps between battery modules, resulting in some battery modules being in a high-temperature environment for a long time, which not only reduces the battery charging and discharging efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an improved air-cooled energy storage cabinet, comprising an energy storage cabinet body, a cabinet door provided on one side of the outer wall of the energy storage cabinet body, an air conditioner installed in the middle of the cabinet door, a filter screen provided at the exhaust port of the air conditioner, and an air supply assembly provided inside the energy storage cabinet body.

[0007] The air supply assembly includes an air inlet guide plate, which is fixedly connected inside the energy storage cabinet body. A fixed frame is fixedly connected to one side of the outer wall of the air inlet guide plate. Two sets of arc-shaped guide plates are fixedly connected to the top of the fixed frame. A linear air supply plate is fixedly connected to the middle side of the top of the fixed frame. Vertical guide plates are fixedly connected to the outer walls of both sets of arc-shaped guide plates.

[0008] Furthermore, a support plate and a fixed top plate are fixedly connected to the top of the fixed frame, and a fixed bottom plate is fixedly connected to the bottom of the fixed frame.

[0009] Furthermore, an air supply base frame is fixedly connected to the lower surface of the fixed base plate, and multiple air supply cross plates are fixedly connected to the outer wall of the fixed base plate.

[0010] Furthermore, the outer wall of the fixed frame is fixedly connected to the inner wall of the energy storage cabinet body.

[0011] Furthermore, the air inlet guide plate is disposed on one side of the air outlet of the air conditioner.

[0012] Furthermore, the two sets of arc-shaped guide vanes are symmetrically arranged on the top of the fixed frame and are designed in an arc shape.

[0013] Furthermore, the support plate and the fixed top plate are disposed on the upper and lower sides of the arc-shaped guide plate and the linear air supply plate.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, through the coordinated operation of components such as the air inlet guide plate, the arc-shaped guide plate, and the vertical guide plate, a scientific airflow guiding system is formed, which can evenly distribute the cooling airflow delivered by the air conditioner to each space inside the energy storage cabinet, effectively avoiding local overheating. At the same time, it enhances the airflow turbulence effect, significantly improves the air cooling efficiency of the battery module, ensures that the battery module inside the energy storage cabinet is always in a good heat dissipation environment, extends the battery life, and improves the reliability and safety of the energy storage system.

[0016] 2. In this utility model, the stable connection between the fixed frame and the energy storage cabinet body, as well as the rigid support structure formed by the bottom fixed base plate and the top fixed top plate, ensure overall stability; the design of the air supply base and air supply cross plate realizes multi-directional guidance of cold airflow, enabling the cold airflow to penetrate the gaps between battery modules in layers, thereby improving the overall heat dissipation; while the limiting and fixing of the airflow guiding structure by the support plate and the fixed top plate not only ensures the stability of the airflow guiding components under the impact of airflow, but also further optimizes the airflow distribution path and extends the cooling airflow path, thus providing a solid guarantee for efficient heat dissipation in terms of structure, combining practicality and durability.

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-4 This utility model provides an embodiment of an improved air-cooled energy storage cabinet, including an energy storage cabinet body 1. A cabinet door 2 is provided on one side of the outer wall of the energy storage cabinet body 1. An air conditioner 3 is installed in the middle of the cabinet door 2. The air conditioner 3 serves as the core supply device for cooling airflow, continuously supplying low-temperature airflow into the energy storage cabinet to provide a cold source for the heat dissipation of the battery modules inside the energy storage cabinet. This is the basis for achieving air-cooled heat dissipation. A filter screen 4 is provided at the exhaust port of the air conditioner 3. The filter screen 4 is made of high-density fiber material, which can effectively intercept dust, particulate matter and other impurities in the air, prevent these pollutants from entering the interior of the energy storage cabinet, prevent contamination of the battery modules, ensure the normal operating environment of the battery modules, and extend their service life. An air supply component is provided inside the energy storage cabinet body 1.

[0025] The air supply assembly includes an air inlet guide plate 5, which is located directly to the side of the air outlet of the air conditioner 3, with its surface forming a 30-degree angle with the outlet. This angle precisely guides the airflow output by the air conditioner 3 to the top area of ​​the fixed frame 6. The air inlet guide plate 5 is fixedly connected to the interior of the energy storage cabinet body 1. A fixed frame 6 is fixedly connected to one side of the outer wall of the air inlet guide plate 5. The fixed frame 6 consists of a bottom fixed plate 7 and a top fixed plate 12 forming a rigid support system. Its outer wall is fixedly connected to the inner wall of the energy storage cabinet body 1, providing stable structural support for the entire energy storage cabinet. Two sets of arc-shaped guide plates 8 are fixedly connected to the top of the fixed frame 6. The arc-shaped guide plates 8 are symmetrically distributed and staggered vertically, and their precision... The precisely calculated arc curvature is based on aerodynamic principles, which can evenly distribute airflow to both sides of the fixed frame 6. The synergistic effect of the two enhances the airflow turbulence effect, allowing the airflow to fully exchange heat with the surface of the battery module, significantly improving the air cooling efficiency of the battery module and achieving uniform heat dissipation. A linear air supply plate 9 is fixedly connected to the top center of the fixed frame 6. Vertical air supply plates 11 are fixedly connected to the outer walls of the two sets of arc-shaped guide plates 8. The air inlet guide plate 5 is set on one side of the air outlet of the air conditioner 3. The two sets of arc-shaped guide plates 8 are symmetrically set on the top of the fixed frame 6 and are designed in an arc shape. The support plate 10 and the fixed top plate 12 are set on the upper and lower sides of the arc-shaped guide plates 8 and the linear air supply plate 9.

[0026] Specifically, the air conditioner 3, as the main cooling airflow supply device, continuously delivers low-temperature airflow into the cabinet. The airflow first passes through the filter 4, which is made of high-density fiber material and can effectively intercept dust, particulate matter, and other impurities in the air, preventing them from entering the energy storage cabinet and contaminating the battery modules. The filtered clean airflow then enters the air supply assembly. The air inlet guide plate 5 is located on the side of the air outlet of the air conditioner 3, with its surface forming a 30-degree angle with the air outlet. This angle design can accurately guide the airflow to the top area of ​​the fixed frame 6. The symmetrically distributed arc-shaped guide plates 8 have a precisely calculated curvature that can fully utilize aerodynamic principles. When the airflow comes into contact with the arc surface structure of the arc-shaped guide plates 8, it is evenly distributed to both sides of the fixed frame 6. At the same time, the vertical guide plate 11 is vertically installed inside the fixed frame 6, and its surface is designed with staggered air guide grooves, which can further guide the airflow for longitudinal diffusion. The support plate 10 and the fixed top plate 12 form a double limiting structure. The support plate 10 is fixed to the middle of the fixed frame 6 by bolts, while the fixed top plate 12 seals and covers the top of the fixed frame 6. Together, they restrict the diffusion direction of the airflow, ensuring that the airflow evenly covers the entire internal space of the energy storage cabinet body 1, effectively preventing local overheating. In addition, the arc-shaped guide plate 8 and the linear air supply plate 9 are arranged in a staggered manner. Their synergistic effect greatly enhances the turbulence of the airflow, making the heat exchange between the airflow and the surface of the battery module more complete, significantly improving the air cooling efficiency of the battery module, and achieving all-round uniform heat dissipation.

[0027] Reference Figures 1-4 The top of the fixed frame 6 is fixedly connected to a support plate 10 and a fixed top plate 12. The fixed top plate 12 is fixed to the inner wall of the top of the energy storage cabinet body 1 by welding. It not only seals the top of the fixed frame 6, but also forms a rigid support structure together with the bottom fixed base plate 7. It also participates in restricting the direction of airflow diffusion. The bottom of the fixed frame 6 is fixedly connected to a fixed base plate 7. The fixed base plate 7 is tightly connected to the inner wall of the bottom of the energy storage cabinet body 1 by high-strength expansion bolts. It is an important part of the fixed frame 6, which enhances the connection strength between the fixed frame 6 and the energy storage cabinet body 1 and further improves the stability of the overall structure. The lower surface of the fixed base plate 7 is fixedly connected to an air supply base frame 13. The outer wall of the fixed base plate 7 is fixedly connected to multiple air supply cross plates 14. The outer wall of the fixed frame 6 is fixedly connected to the inner wall of the energy storage cabinet body 1.

[0028] Specifically, the fixed frame 6 consists of a bottom fixed base plate 7 and a top fixed top plate 12, forming a stable rigid support system. The bottom fixed base plate 7 is tightly connected to the bottom inner wall of the energy storage cabinet body 1 using high-strength expansion bolts, while the top fixed top plate 12 is fixed to the top inner wall of the energy storage cabinet body 1 using welding technology, ensuring that the entire fixed frame 6 and the energy storage cabinet body 1 form a solid integrated structure. The air supply base 13 has an L-shaped structure, with its vertical side connected to the fixed base plate 7 by screws, and its horizontal side extending to the bottom of the battery module, which can guide some airflow downwards for targeted heat dissipation of the bottom of the battery module. The air supply cross plate 14 extends in a ring around the outer wall of the fixed base plate 7, and its surface is evenly distributed with multiple strip-shaped air outlets. The size and spacing of these air outlets are optimized to form a multi-directional air outlet channel, allowing the cold airflow to penetrate the gaps between the battery modules in layers, achieving three-dimensional heat dissipation. The support plate 10 and the fixed top plate 12 strictly constrain the vertical displacement of the arc-shaped guide plate 8. The support plate 10 is provided with a limiting groove, in which the lower end of the arc-shaped guide plate 8 is embedded. The fixed top plate 12 presses and fixes the upper end of the arc-shaped guide plate 8 through a pressure plate structure, ensuring that the guide structure remains stable under the impact of strong airflow. At the same time, it further optimizes the airflow distribution path, extends the travel of the cooling air inside the energy storage cabinet, and maximizes the heat dissipation efficiency.

[0029] Working principle: When the improved air-cooled energy storage cabinet is needed, the air conditioner 3 delivers cooling airflow into the cabinet. After being filtered by the filter screen 4, the airflow enters the air supply assembly. The air inlet guide plate 5 is located on one side of the air outlet of the air conditioner 3, which guides the airflow to the top of the fixed frame 6. The symmetrically arranged arc-shaped guide plates 8 divide the airflow to both sides through the arc surface structure. At the same time, the vertical guide plate 11 further guides the airflow to diffuse longitudinally. With the limiting effect of the support plate 10 and the fixed top plate 12, the airflow evenly covers the internal space of the energy storage cabinet body 1, avoiding local overheating. The coordinated design of the arc-shaped guide plate 8 and the linear air supply plate 9 enhances the airflow turbulence effect, improves the air cooling efficiency of the battery module, and achieves uniform heat dissipation.

[0030] In addition, the fixed frame 6 forms a rigid support structure through the bottom fixed base plate 7 and the top fixed top plate 12. Its outer wall is fixedly connected to the inner wall of the energy storage cabinet body 1 to ensure overall stability. The air supply base 13 is connected to the fixed base plate 7 to guide some airflow downwards, while the air supply cross plate 14 extends along the outer wall of the fixed base plate 7 to form a multi-directional air outlet channel, allowing the cold airflow to penetrate the gap between the battery modules in layers. The support plate 10 and the fixed top plate 12 respectively constrain the vertical displacement of the arc-shaped guide plate 8 to ensure that the guide structure remains stable under the impact of airflow, while optimizing the airflow distribution path and extending the cooling air path.

Although the present utility model 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.
