Description

Technical Field

[0001] This utility model belongs to the field of energy storage equipment technology, and in particular to an AC-to-DC energy storage power cabinet. Background Technology

[0002] With the widespread application of renewable energy and the development of smart grids, the importance of energy storage technology is becoming increasingly prominent. Currently, there are many types of energy storage cabinets on the market. Alternating current (AC-DC) energy storage cabinets may cause heat to accumulate inside during operation, making it difficult to dissipate and resulting in poor heat dissipation, which affects the performance and lifespan of the energy storage equipment. While existing AC-DC energy storage cabinets can meet basic heat dissipation requirements, the incoming air is not filtered, leading to dust accumulation inside the cabinet and reduced heat dissipation efficiency.

[0003] A search revealed Chinese patent documents (authorization announcement number CN218919101U), indicating that this utility model relates to the field of energy storage power cabinet technology, and discloses an alternating current energy storage power cabinet, including a bottom shell, a battery pack mounting bracket fixedly installed on the top of the bottom shell, a battery pack mounted on the inner side of the battery pack mounting bracket, a battery pack side mounting bracket bolted to the front side of the battery pack mounting bracket and located in front of the battery pack, a front shell fixedly installed on the top of the bottom shell and located near the front, and a handle fixedly installed on the side of the front shell and located near the top. This AC-to-DC energy storage power cabinet can be quickly disassembled and assembled through the cooperation of the bottom shell, expansion top shell, XT connector A, and XT connector B. This facilitates the movement and transportation of the energy storage power cabinet, reducing the difficulty of movement and transportation. Multiple expansion energy storage power cabinets can be spliced ​​and installed according to the required usage conditions, thus adapting to different power conditions and improving the applicable environment of the energy storage power cabinet. It is easy to use. The energy storage power cabinet can meet basic heat dissipation requirements. However, the incoming air is not filtered, which leads to dust accumulation inside the AC-to-DC energy storage power cabinet and reduces heat dissipation efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an AC-to-DC energy storage power cabinet to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an AC-to-DC energy storage power cabinet, comprising an energy storage power cabinet body for energy storage, a heat dissipation box provided on the side of the energy storage power cabinet body, an air guide plate installed inside the heat dissipation box, rotating blades and an L-shaped plate connected to the side of the air guide plate, a hollow column installed on the top of the L-shaped plate, a spring provided inside the hollow column, a connecting column connected to the end of the spring away from the L-shaped plate, a filter frame slidably installed on the end of the connecting column away from the L-shaped plate, a filter plate provided inside the filter frame, and a first air inlet for air entry and a display screen for display provided on the side of the heat dissipation box.

[0011] Preferably, the side of the heat dissipation box is provided with a sealing plate for replacing the drying plate and a second air inlet for air to enter.

[0012] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0013] This AC-to-DC energy storage power cabinet benefits from the structure of the heat dissipation box. The rotating blades bring impurities in the air into contact with the filter plate for filtration. As impurities adhere to the filter plate, its air permeability is reduced. The filter frame presses down on the connecting column, and the connecting column presses down on the spring. The filter frame can be removed through the sliding groove between the filter frame and the connecting column to replace the filter plate. This structure filters the incoming air, preventing dust accumulation inside the AC-to-DC energy storage power cabinet and improving heat dissipation efficiency.

[0014] This convertible energy storage cabinet, thanks to the structure of the drying rack, allows the telescopic rod to extend after a certain period of time, pushing a new drying plate. The new drying plate then pushes the used drying plate at the drying port. The used drying plate enters the recycling box through the recycling port. This structure dries the incoming air and can automatically replace the drying plate at the drying port, reducing manual operation, saving replacement time, and improving drying efficiency.

[0026] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0027] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0028] like Figures 1 to 8 The diagram illustrates an AC-to-DC energy storage power cabinet, comprising a cabinet body 1 for energy storage, with a heat dissipation box 2 located on the side of the cabinet body 1. The cabinet body 1 is typically made of steel plate, such as cold-rolled steel plate or galvanized steel plate. Cold-rolled steel plate has good strength and processing performance, and its thickness is generally 1.5-3mm. Galvanized steel plate has better corrosion resistance and is suitable for outdoor use. The metal casing needs to have a certain electromagnetic shielding capability, therefore, the conductivity of the material is required, generally requiring the material's conductivity to be within a certain range, for example, a conductivity of 5×10⁻⁶. 6 -1×10 7S / m, to reduce electromagnetic interference. An air guide plate 203 is installed inside the heat sink 2. A rotating blade 204 and an L-shaped plate 208 are connected to the side of the air guide plate 203. A hollow column 207 is installed on the top of the L-shaped plate 208. A spring 210 is installed inside the hollow column 207. A connecting column 209 is connected to the end of the spring 210 away from the L-shaped plate 208. A filter frame 205 is slidably installed on the end of the connecting column 209 away from the L-shaped plate 208. A filter plate 206 is installed inside the filter frame 205. The side of the heat sink 2 is provided with... Air enters through the first air inlet 202 and the display screen 201. Air enters the heat sink 2 through the first air inlet 202. The rotating blades 204 rotate, and impurities in the air come into contact with the filter plate 206 for filtration. After a period of time, impurities adhere to the filter plate 206, and the air permeability decreases. The filter frame 205 presses down on the connecting column 209, and the connecting column 209 presses down on the spring 210. The filter frame 205 can be removed through the sliding groove between the filter frame 205 and the connecting column 209 to replace the filter plate 206.

[0029] A drying rack 3 is installed on the vertical inner wall of the heat dissipation box 2. A telescopic rod 301 is connected to the vertical inner wall of the drying rack 3. A push plate 302 is installed on the movable part of the telescopic rod 301. A drying port 304 is provided at the top of the drying rack 3. A recycling port 305 and a recycling box 306 are provided at the bottom of the drying rack 3. A drying plate 303 is provided inside the drying rack 3. Filtered air comes into contact with the drying plate 303 through the drying port 304 for drying. After a certain period of time, the telescopic rod 301 extends, and the push plate 302 pushes a new drying plate 303. The new drying plate 303 pushes the used drying plate 303 at the position of the drying port 304. The used drying plate 303 enters the recycling box 306 through the recycling port 305. The filtration module consists of a filter frame 205, a filter plate 206, a hollow column 207, a spring 210, and a connecting column 209. The filter plate 206 is arranged perpendicular to the airflow channel, forming a protective structure that precisely intercepts impurities. The filter frame 205 is elastically connected to the connecting column 209 via the spring 210, ensuring a tight fit with the airflow channel and effectively preventing path deviation caused by airflow leakage. This ensures stable filtration resistance and reduces energy loss. When the impurities on the filter plate 206 reach a set threshold, it can be quickly disassembled and replaced, ensuring that the airflow efficiency remains within a reasonable range. After filtration, the air enters the drying module, which includes a drying frame 3, a telescopic rod 301, a push plate 302, a drying plate 303, a drying port 304, a recovery port 305, and a recovery box 306. The drying port 304 is precisely aligned with the airflow channel. The drying plate 303 is made of a highly breathable material, achieving moisture adsorption while minimizing airflow resistance. Once the drying plate 303 is saturated with adsorption, the telescopic rod 301 drives the push plate 302 to automatically replace the drying plate. The waste drying plate falls into the recycling box 306 through the recycling port 305. The whole process does not require stopping the machine, thus avoiding the impact of airflow interruption on heat dissipation efficiency.

[0030] The heat sink 2 houses a cooling box 4. A water inlet pipe 401 is connected to the side of the cooling box 4, and heat sink 402 is installed at the bottom. A baffle 403 is installed on the vertical inner wall of the heat sink 2, and a fan 404 is installed on the top of the baffle 403. Dried air is cooled by passing through the cooling box 4 and the heat sink 402. The cooling water in the cooling box 4 can be replaced through the water inlet pipe 401. The dried air enters the cooling module. The cooling box 4 is positioned close to the airflow channel, and the heat sink 402 at the bottom significantly increases the heat exchange area. The baffle 403 at the top of the cooling box 4 is equipped with a fan 404, which pressurizes the air downwards, propelling the cooled air quickly into the cabinet through the second air inlet 6, effectively preventing secondary heat accumulation caused by backflow of cooling air. Furthermore, the airflow is initially guided by the air guide plate 203 to form a directional flow, reducing turbulence losses. The rotating blades 204 provide additional power to the airflow, compensating for the velocity attenuation during filtration and drying, ensuring stable airflow energy throughout the process, and reducing energy loss at the source. A drain outlet is reserved at the bottom of the cooling box 4 corresponding to the water inlet pipe 401. When replacing the cooling water, the waste water is first discharged through the drain outlet, and then new water is injected through the water inlet pipe 401, forming a "water inlet-drainage" closed loop, avoiding the decrease in cooling efficiency caused by waste water residue. For cleaning and maintenance, the sealing plate 5 on the side of the heat sink 2 adopts a detachable design. After disassembly, the entire cooling box 4 can be removed, facilitating the cleaning of scale and dust on the inner wall of the box and the surface of the heat sink 402. The heat sink 402 is connected to the cooling box 4 by clips, supporting individual disassembly and cleaning without affecting the operation of other components. The baffle 403 is movably connected to the inner wall of the heat sink 2. After opening, the fan 404 and the surface of the cooling box 4 can be cleaned directly, ensuring the long-term stability of the heat exchange efficiency of the cooling system.

[0031] The bottom of the energy storage power cabinet 1 is equipped with a fixed plate 103 and casters 104. The side of the cabinet 1 has a transfer connection plate 102 for connection; external devices obtain power by connecting to the transfer connection plate 102. The top of the cabinet 1 is equipped with a top cover 101. The interior of the cabinet 1 has multiple ventilation baffles 801, dividing the cabinet into several independent but interconnected heat dissipation channels. Each channel corresponds to one energy storage position 8, ensuring that cooling airflow can evenly cover all energy storage devices and eliminating airflow blind spots. The ventilation baffles 801 are made of high-strength aluminum alloy profiles or steel. Aluminum alloy profiles have the advantages of being lightweight, high-strength, and corrosion-resistant, with a tensile strength generally between 200-300 MPa. Steel has even higher strength; for example, high-strength structural steel can achieve a yield strength of 300-500 MPa, but it is relatively heavier. When selecting an energy storage power cabinet, factors such as weight, load-bearing capacity, and cost need to be comprehensively considered. The ventilation partition 801 has multiple ventilation holes for easy ventilation. Energy storage positions 8 are provided between the multiple ventilation partitions 801 for placing energy storage equipment. Battery modules are placed in the energy storage positions 8. Air outlets 7 are provided on the sides of the energy storage power cabinet body 1 for air exhaust. A sealing plate 5 is provided on the side of the heat dissipation box 2 for replacing the dryer plate 303. The sealing plate 5 can be opened to replace the dryer plate 303 and filter plate 206. A second air inlet 6 is provided on the side of the heat dissipation box 2 for air intake. Through the ventilation partitions 801, heat exchange occurs with the heating elements inside the energy storage power cabinet body 1, and the heat is finally exhausted through the air outlets 7. The ventilation partitions 801 are made of a material with excellent thermal conductivity and have dense ventilation holes on their surface, serving both as support for the energy storage equipment and for heat conduction, quickly transferring the heat generated during equipment operation into the airflow. After entering the bottom of the cabinet through the second air inlet 6, the cooling airflow flows upward along the heat dissipation channel, coordinating with the natural upward trend of hot air to create a stable "bottom-in, top-out" airflow circulation, accelerating heat dissipation. The side air outlet 7 is precisely aligned with the top of the ventilation baffle 801, allowing hot air from each channel to be directly exhausted, avoiding localized heat accumulation caused by the mixing of hot air from different channels; the opening area of ​​the air outlet 7 matches that of the air inlet, maintaining the air pressure balance inside the cabinet and further improving the uniformity of heat dissipation.

[0032] The equipment must be deployed in a dry, well-ventilated indoor environment with humidity controlled between 30% and 60%. This prevents humid air from entering through the first air inlet 202 and the second air inlet 6, which could cause short circuits in the internal circuitry or excessively rapid saturation of the drying plate 303. It should be kept away from dusty areas (such as factory workshops or construction sites). If this cannot be avoided, a front dust cover should be installed outside the air inlet to reduce the pressure of impurities adhering to the filter plate 206. Simultaneously, the ambient temperature should be maintained between -10℃ and 40℃ to prevent extreme temperatures from causing the cooling water in the cooling box 4 to freeze or reducing the heat exchange efficiency of the heat sink 402, ensuring stable operation of the electronic components of the AC-DC conversion module.

[0033] The filtration system requires regular inspection. When it is observed that the filter frame 205 is pressed down on the connecting column 209 by more than 1cm due to impurities, the sealing plate 5 must be opened immediately, and the filter frame 205 must be removed along the slide groove to replace the filter plate 206, to avoid insufficient air permeability affecting the heat dissipation airflow. The drying system needs to be replenished with new drying plates 303 weekly, and the old drying plates in the recycling box 306 should be emptied to prevent the recycling port 305 from being blocked and preventing the drying plates from being replaced properly. The cooling system requires monthly replacement of the cooling water in the cooling tank 4 by injecting clean soft water through the water inlet pipe 401 to prevent scale from adhering to the surface of the heat sink 402 and reducing the heat conduction efficiency; the dust on the heat sink 402 and the fan 404 blades should be cleaned quarterly to ensure smooth airflow. The ventilation baffle 801 of the energy storage position 8 needs to be wiped regularly to prevent dust accumulation from clogging the ventilation holes and affecting the air circulation inside the cabinet.

[0034] Core components must be made of materials suitable for the operating conditions: the energy storage power cabinet 1 is made of galvanized cold-rolled steel plate with a thickness of not less than 2mm to enhance corrosion resistance and structural strength; the filter plate 206 uses a high-density HEPA filter with a filtration accuracy of H13 level, effectively intercepting fine dust; the drying plate 303 uses highly absorbent silica gel to ensure moisture absorption capacity and regeneration performance; the cooling box 4 is made of 304 stainless steel to prevent cooling water from corroding the box; the spring 210 is made of stainless steel to avoid corrosion caused by long-term stress and environmental humidity, ensuring the elastic reset function of the filter frame 205. All electrical connections (such as the AC / DC connection plate 102) use silver-plated terminals to improve conductivity and oxidation resistance.

[0035] Strengthen the sealing design of key components: Weather-resistant rubber gaskets are installed at the connection between the heat dissipation box 2 and the energy storage cabinet 1 to prevent rainwater or dust from seeping in through gaps; the mating surface of the sealing plate 5 and the heat dissipation box 2 adopts a labyrinth-style sealing structure, coupled with fastening bolts to ensure a tight seal; waterproof louvers are installed at the first air inlet 202, the second air inlet 6, and the air outlet 7, ensuring ventilation while preventing water droplet intrusion; the top cover 101 adopts a sloping design and is equipped with waterproof rubber strips to prevent water accumulation and seepage from the top. Regularly check the aging of the seals, and replace them promptly if cracks or deformation are found to ensure continuous and effective sealing performance.

[0036] During installation, ensure precise fit of all components: the connection between the air guide plate 203 and the rotating blade 204 must be secure to prevent vibration during operation that could cause airflow deviation; the sliding fit between the connecting column 209 and the hollow column 207 must be smooth, and lubricant should be applied regularly to prevent jamming that could affect the disassembly and repositioning of the filter frame 205; the installation positions of the telescopic rod 301 and the push plate 302 must be aligned with the pushing path of the drying plate 303 to ensure smooth movement of the drying plate during replacement, without jamming or tilting; the fan 404 and the baffle 403 must be firmly fixed to prevent resonance during operation, while ensuring that the fan outlet faces the cooling box 4 to maximize airflow pushing efficiency. Regularly check the tightness of the component connecting bolts to prevent loosening that could affect operational stability.

[0037] Operators must undergo professional training before starting work: When installing the equipment, ensure that the casters 104 are locked and the fixed plate 103 is firmly grounded to prevent equipment displacement or leakage; when connecting external equipment, the power supply to the energy storage cabinet must be disconnected first, and then wiring should be done through the AC direct connection plate 102. After wiring, check whether the terminals are tight to prevent poor contact that could cause overheating; when replacing filter plates, drying plates, or cooling water, the fan 404 must be turned off and the equipment must be cooled before operation to avoid hand injury from contact with high-temperature components; monitor the equipment operating parameters in real time through the display screen 201. If abnormal temperature or decreased heat dissipation efficiency is found, stop the machine immediately for troubleshooting. It is strictly forbidden to operate the equipment with a fault.

[0038] In terms of safety protection, the energy storage power cabinet 1 is equipped with an overload protection module and a leakage detection device, which are linked with the AC direct connection plate 102. When an overload or leakage is detected, the power supply is automatically cut off and an alarm is issued through the display screen 201 to avoid equipment damage or electric shock risks. The heat dissipation box 2 is equipped with a temperature sensor to monitor the temperature of the cooling box 4 and the heat dissipation channel in real time. If the temperature exceeds 50°C, the fan 404 is automatically started in high-speed operation mode, and the cooling water circulation acceleration mechanism of the cooling box 4 is triggered to quickly cool down and prevent overheating. In terms of intelligent monitoring optimization, the display screen 201 can be expanded to display parameters such as the degree of blockage of the filter plate 206, the moisture absorption saturation of the drying plate 303, and the cooling water quality. The pressure sensor of the connecting column 209 provides feedback on the downward pressure of the filter frame 205. The drying frame 3 is equipped with a humidity sensor to detect the performance of the drying plate. When the data exceeds the standard, maintenance is automatically prompted to achieve precise management. In terms of special scenario adaptation, for outdoor or harsh environment use needs, the energy storage power cabinet 1 adopts IP54 protection design, the top cover 101 is equipped with lightning protection grounding device, and the first air inlet 202 and the second air inlet 6 are equipped with mosquito net covers; the moving wheels 104 are upgraded to universal self-locking wheels, which are fixed with the expansion bolt structure of the fixed plate 103 to take into account both the ease of movement and the stability of installation; the energy storage position 8 can adjust the spacing of the ventilation partition 801 according to the size of the energy storage equipment, and supports the parallel connection of multiple cabinets through the reserved expansion interface to adapt to different power demand scenarios.

[0039] Working principle

[0040] In this AC-to-DC energy storage power cabinet, external devices obtain power through the AC-to-DC connection plate 102. The cabinet body 1 is divided into multiple energy storage positions 8 by a ventilation partition 801, with battery modules placed in these positions. The ventilation holes in the partition 801 provide channels for heat dissipation. During heat dissipation, air enters through the first air inlet 202 of the heat dissipation box 2. The air guide plate 203 directs the airflow, and rotating blades 204 supplement the kinetic energy of the airflow. The airflow first passes through the filter module, where the filter plate 206 in the filter frame 205 intercepts impurities. The filter frame 205 is elastically fitted to the connecting column 209 by a spring 210 to prevent airflow leakage. When the filter plate 206 is covered with too many impurities, the filter frame 205 can be directly removed and replaced. Filtered air enters the drying rack 3 through the drying port 304, comes into contact with the drying plate 303 to remove moisture. Once the drying plate 303 is saturated, the telescopic rod 301 pushes the push plate 302 to deliver a new drying plate 303 to the drying port 304. The used drying plate 303 falls into the recycling box 306 through the recycling port 305, achieving replacement without shutting down the machine. The dried air enters the cooling box 4, which is injected with cooling water through the water inlet pipe 401. The heat sink 402 at the bottom expands the heat exchange area, and the fan 404 at the top of the baffle 403 blows air downwards and pressurizes it, pushing the cooled air through the second air inlet 6 into the bottom of the cabinet 1. The airflow flows upward along the heat dissipation channel formed by the ventilation baffle 801, exchanging heat with the energy storage device. The hot air is finally discharged through the air outlet 7, creating a "bottom in, top out" airflow circulation. The sealing plate 5 on the side of the heat dissipation box 2 is removable, which makes it easy to replace the filter plate 206, the drying plate 303 and clean the cooling box 4 and the heat dissipation fins 402. The casters 104 at the bottom of the energy storage power cabinet 1 make it easy to move. The fixed plate 103 ensures stable placement. The top cover 101 protects the top of the cabinet. All components work together to achieve efficient operation of energy supply and heat dissipation.
