Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic component recycling, and more specifically to an efficient and fast-assembled 60KW energy storage device energy-saving ventilation and noise reduction structure. Background Art

[0002] With the continuous growth of global energy demand and the rapid development of renewable energy, the application of energy storage technology in energy management, load regulation and power stability assurance has become particularly important. Energy storage equipment usually operates in high-power, high-density environments, and the heat and noise generated during operation become important limiting factors for improving equipment performance. In addition, in the application environment, energy storage equipment needs to meet multiple requirements of efficient heat dissipation, low-noise operation and convenient assembly. However, existing technologies still have significant deficiencies in these aspects:

[0003] 1. Noise control issues

[0004] Noise sources: The main noise sources in the operation of energy storage equipment include mechanical vibrations generated by batteries, motors and other equipment during operation, air conditioning fans, compressors, electromagnetic components, etc. Especially when the fan is running at high speed, the collision and vibration of air flow and the internal structure of the equipment will cause eddy current noise and air noise.

[0005] Current issues:

[0006] Insufficient processing of low-frequency noise: Traditional noise reduction technology is usually optimized for high-frequency noise, while low-frequency noise (such as 50Hz-200Hz noise generated by fans and compressors) is difficult to be effectively absorbed and attenuated due to its long wavelength and large propagation range.

[0007] Noise attenuation and ventilation conflict: Many noise reduction designs will cause air flow obstruction, increase air resistance (pressure loss) inside the equipment, thereby affecting fan efficiency and even increasing energy consumption.

[0008] 2. Heat dissipation and ventilation efficiency issues

[0009] Importance of heat dissipation: Energy storage equipment will generate a lot of heat when it is running for a long time. If the heat dissipation is not timely, it will cause the equipment to overheat, affecting the life of core components and performance stability.

[0010] Current issues:

[0011] Excessive pressure loss: After adding silencer components to some traditional designs, the air resistance in the ventilation path increases significantly, resulting in a decrease in the ventilation efficiency inside the equipment.

[0012] Air flow turbulence: In existing energy storage devices, the design of the air inlet and exhaust channels is not fully optimized, and air flow short circuits and eddy currents often occur, further reducing the heat dissipation efficiency.

[0013] 3. Assembly and maintenance issues

[0014] Current situation: The internal components of energy storage devices usually use complex fixing and connection methods, and the assembly and maintenance process is time-consuming and labor-intensive. Especially in an environment with high demand for modular updates, this traditional design greatly increases the difficulty of operation and maintenance.

[0015] Current issues:

[0016] Complex component fixation: Traditional components rely on multi-point bolt fixation, which makes disassembly and assembly difficult and has low maintenance efficiency.

[0017] Insufficient modular design: The internal components of existing energy storage devices are mostly integrated designs, which is not convenient for rapid replacement and upgrading of individual components.

[0018] 4. Environmental adaptability issues

[0019] Adapt to environmental requirements: Energy storage equipment is widely used in outdoor environments and may face problems such as dust, high humidity, and intrusion of small animals. The equipment needs to have certain protection functions to adapt to harsh operating environments.

[0020] Current issues:

[0021] Insufficient protection capabilities: Traditional equipment design does not adequately consider the adaptability to the external environment, and the air inlet of the equipment is easily blocked by dust or foreign matter, affecting operational safety.

[0022] Poor durability in long-term use: Especially in outdoor environments, the protective structure has insufficient anti-corrosion performance, the equipment is easily damaged by the natural environment, and the maintenance cost is increased.

[0023] 5. Market and technology requirements

[0024] Efficient operation requirements: In the industrial and commercial fields, energy storage equipment needs to meet the requirements of low energy consumption and high efficiency at the same time. Especially in noise-sensitive places (such as hospitals, residential areas and schools), there are strict requirements on the noise reduction performance of the equipment.

[0025] Modularity and flexibility requirements: As the application scenarios and functional requirements of energy storage equipment become increasingly diverse, modular design has become an inevitable trend, requiring equipment to be quickly assembled, upgraded and maintained while maintaining high reliability.

[0026] Therefore, it is of great significance to design a ventilation and noise reduction structure for energy storage equipment that has the characteristics of efficient ventilation, noise reduction and rapid assembly. Summary of the invention

[0096] The metal frame 5 is located between the exhaust silencer structure 2 and the inlet silencer structure 3. The metal frame 5 is provided with two rectangular plug holes for installing a plug-in silencer module 501. The plug-in silencer module 501 is a hollow structure or filled with sound-absorbing material.

[0097] The bird-proof net 7 is made of a metal woven net and is installed on the outside of the exhaust silencer structure 2 and the inlet silencer structure 3 respectively to prevent animals such as birds and rodents from entering the interior of the equipment.

[0098] In order to further optimize the above solution, the ventilation static pressure cavity (101) is enclosed by a metal shell to enhance structural strength and durability; the cavity thickness is 120 mm to reduce air movement resistance and ensure stable air flow.

[0099] In order to further optimize the above solution, the first top sound-absorbing sheet 201 and the first bottom sound-absorbing sheet 202 have an inclination angle of 45°, and a perforation rate of 23%-32%.

[0100] In order to further optimize the above solution, the inclination angle of the second top sound-absorbing sheet 301 and the second bottom sound-absorbing sheet 302 is 45°, and the perforation rate thereof is 23%-32%.

[0107] Example 2

[0108] like Figure 8 As shown, the working principle of this application is as follows:

[0109] The working principle of the present invention is based on the comprehensive optimization of aerodynamics, noise propagation characteristics and thermal management requirements during the operation of energy storage equipment. By rationally designing the ventilation static pressure cavity, air inlet and exhaust silencer structure, arc-shaped silencer blades and modular components, the goals of noise reduction, improved ventilation efficiency and stable operation of the equipment are achieved. The following is the specific working principle:

[0110] 1. Function of ventilation static pressure structure 1

[0111] Functional principle:

[0112] The ventilation static pressure structure 1 is located in the core airflow channel of the energy storage device, and a ventilation static pressure cavity 101 is formed inside it. When the device is running, high-speed air flows through the cavity, and the static pressure cavity reduces air flow resistance by reducing air flow speed and uniformizing air flow distribution.

[0113] Implementation mechanism:

[0114] The static pressure chamber avoids eddies and pressure fluctuations through the internal cavity design, making the air flow smoother, thereby reducing the air noise and ventilation pressure loss that may be generated during equipment operation.

[0115] By quickly assembling the hanging hinge structure 6, the static pressure chamber can be quickly connected to the entire device and is easy to disassemble and assemble during daily maintenance.

[0116] 2. Synergistic noise reduction of air inlet silencer structure 3 and exhaust silencer structure 2

[0117] Air inlet silencer structure 3:

[0118] Absorb the noise caused by external air flow.

[0119] The second top sound-absorbing sheet 301 and the second bottom sound-absorbing sheet 302 are designed in a trapezoidal shape. The inclination angle and the porosity (23%-32%) of the perforated plate are matched with the air spectrum to specifically absorb medium and low frequency noise.

[0120] The arc-shaped silencer blades 4 are evenly distributed inside the air inlet silencer structure to further absorb high-frequency and medium-frequency noise caused by the air duct design.

[0121] Exhaust silencer structure 2:

[0122] Reduce the noise generated inside the equipment from being transmitted to the outside through the exhaust duct.

[0123] The first top silencer sheet 201 and the first bottom silencer sheet 202 are designed to be tilted to match the airflow direction, thereby guiding the airflow to flow out smoothly and absorbing the noise caused by exhaust.

[0124] Synergistic Effects:

[0125] The isolation design of the air inlet and exhaust channels prevents the airflows from interfering with each other and forming vortices through independent noise reduction structures, thus achieving effective noise attenuation.

[0126] 3. Noise reduction and airflow optimization of arc-shaped silencer blade 4

[0127] principle:

[0128] One side of the arc-shaped silencer blade is a smooth surface for guiding the airflow to pass smoothly; the other side is a perforated plate 401, the interior of which is a hollow structure or filled with high-density hydrophobic sound-absorbing cotton 402 for absorbing the noise generated by the airflow.

[0129] Function:

[0130] Reduce the noise caused by high-speed airflow through narrow spaces.

[0131] The internal hydrophobic sound-absorbing cotton 402 has a significant attenuation effect on low-frequency and medium-frequency noise through its sound-absorbing characteristics.

[0132] Linkage with air inlet and exhaust ducts:

[0133] The curved blades are evenly distributed in the air inlet and exhaust channels, with a spacing of 270mm and an inclination angle of 45°, ensuring smooth transition of air flow and minimizing air disturbance.

[0134] 4. Modular noise reduction function of plug-in silencer module 501

[0135] Design and Fixing:

[0136] The plug-in silencer module 501 is installed through the rectangular socket on the metal frame 5, and the lock fastening makes it easy to disassemble and assemble, which is suitable for equipment maintenance and replacement.

[0137] Noise reduction effect:

[0138] The interior of the module is hollow or filled with sound-absorbing material, which, combined with its rectangular design, forms an airflow buffer zone to reduce the flow noise of high-speed airflow.

[0139] The modular design ensures the uniformity of the intake and exhaust airflow, and further improves the overall noise reduction effect.

[0140] Heat dissipation and maintenance optimization:

[0141] The spacing between the silencer modules is designed to be consistent with the spacing of the forklift's front forks, which facilitates the overall movement of the equipment and improves the maintainability of the energy storage equipment.

[0142] 5. Safety protection function of bird-proof net 7

[0143] principle:

[0144] The bird-proof net is installed on the outside of the air inlet and exhaust channels. It is made of stainless steel and the mesh diameter is designed to be 5mm to 15mm. It can effectively prevent small animals such as birds and mice from entering the equipment.

[0145] Protection effect:

[0146] The bird-proof net ensures that key components inside the equipment are not invaded by small animals without affecting the ventilation efficiency.

[0147] An anti-corrosion coating enhances its durability in long-term outdoor applications.

[0148] 6. Comprehensive effect of equipment operation

[0149] Ventilation Optimization:

[0150] The ventilation static pressure cavity, arc-shaped silencer blades and trapezoidal silencer sheets work together to make the airflow path inside the equipment smooth and stable, effectively reducing air resistance and improving heat dissipation efficiency.

[0151] like Fig. 9 As shown, the output of the equipment under 100% operating conditions (12000m 3 / h) to perform pressure simulation calculation; the calculation result is:

[0152]

[0153] According to the simulation cloud map and calculation results, it can be seen that the pressure loss of the air outlet louver is about 33.9Pa, the pressure loss of the air inlet louver is about 12.8Pa, and the total pressure loss of NP300+120 free-field silencer louvers is 46.7Pa.

[0154] like Fig.10 and Fig.11 As shown, there is only a weak backflow at the boundary of the adjacent air outlets, and the main flows basically do not interfere with each other;

[0155] Noise Control:

[0156] From the air inlet duct to the exhaust duct, the full-chain noise reduction design covers the different frequency bands of noise generated during the operation of the equipment, reducing the overall operating noise of the equipment by more than 15dB(A).

[0157] Quick assembly and maintenance:

[0158] The hanging hinge and modular silencer component design ensure that the equipment is easy to assemble and maintain, reducing the time cost of operation interruption.
