Description
Technical Field
[0001] This invention relates to the technical field of cabinets, and in particular to a PCS energy storage inverter cabinet. Background Technology
[0002] With the continuous optimization of the global energy structure and the increasing penetration rate of renewable energy, the flexibility and operational stability of power systems have become core issues for their sustainable development. Against this backdrop, energy storage systems (ESS) play a crucial role in smart power systems, significantly improving the reliability and resilience of power supply by enabling flexible storage and release of electrical energy. Among these, the power conversion system (PCS), as a key interface of the energy storage system, is responsible for converting DC energy storage into AC power for grid connection, thereby efficiently managing the bidirectional energy flow between the energy storage unit and the grid.
[0003] As the core equipment within an energy storage system that enables the conversion, storage, and release of electrical energy, the performance of the PCS energy storage inverter cabinet directly determines the overall system's operating efficiency and reliability. However, in extreme operating environments such as the Middle Eastern deserts, these cabinets must withstand the harsh tests of ambient temperatures exceeding 50°C, intense sunlight, and pervasive sandstorms for extended periods.
[0004] Existing traditional air-cooled heat dissipation systems exhibit significant limitations under such conditions, specifically: dust causing filter clogging, accelerated fan wear, and a substantial decrease in heat dissipation efficiency at high temperatures. These problems cause power devices inside the cabinet to frequently trigger over-temperature protection mechanisms, forcing the system to operate at derating or even shut down completely. This not only severely damages the operational reliability and energy conversion efficiency of the energy storage system but also significantly increases the high maintenance costs associated with regular cleaning and replacement of core components. Summary of the Invention
[0005] This application provides a PCS energy storage inverter cabinet that can cope with extreme high temperature and high dust environments and achieve efficient and long-life adaptive heat dissipation, thereby significantly reducing maintenance frequency and operating costs and ensuring continuous and stable operation of the cabinet under harsh conditions.
[0006] This application provides a PCS energy storage inverter cabinet, which adopts the following technical solution: A PCS energy storage inverter cabinet includes a cabinet body, a heat dissipation vent disposed on the side of the cabinet body, rotatable louvers, a cooling fan, a baffle, a dust filter, a condenser pipe, and a vibration assembly. The louvers are disposed inside the heat dissipation vent, the cooling fan is disposed inside the cabinet body near the heat dissipation vent, the baffle is disposed inside the heat dissipation vent, the dust filter is disposed between the baffle and the cooling fan, the condenser pipe is disposed between the cooling fan and the dust filter, and the vibration assembly is connected to the dust filter and is used to drive the dust filter to produce periodic deformation.
[0007] Preferably, the baffle has a broken-line cross-section, and an inclined guide plate is provided at the bottom of the baffle, with the inclined direction of the guide plate facing the heat dissipation port.
[0008] Preferably, the dust filter element includes a fixed plate, a movable plate, and at least two corrugated filter elements. A chamber for accommodating the filter elements is formed between the fixed plate and the movable plate. The surface of the filter elements is provided with spherical particle protrusions. The movable plate is connected to the vibration assembly.
[0009] Preferably, both the fixed plate and the movable plate are provided with longitudinal strip-shaped air holes inside, and the longitudinal strip-shaped air holes match the corrugation direction of the filter element.
[0010] Preferably, the corrugated surface of the filter element is provided with a plurality of reset positioning strips, the reset positioning strips being elastically corrugated and fixedly connected to the substrate layer of the filter element.
[0011] Preferably, the ripple amplitude of the reset positioning strip is the same as the original ripple amplitude of the filter core, and the reset positioning strip is made of metal wire or high-strength elastic plastic.
[0012] Preferably, the vibration component includes a motor and a transmission mechanism. The motor drives the movable plate to reciprocate along the cabinet slide rail through the transmission mechanism. The distance between the movable plate and the fixed plate changes periodically with the reciprocating motion.
[0013] Preferably, the transmission mechanism includes an eccentric wheel and a connecting rod. The eccentric wheel is fixedly connected to the output shaft of the motor, one end of the connecting rod is hinged to the eccentric wheel, and the other end is hinged to the sliding bracket of the movable plate.
[0014] Preferably, a vent hole is provided at the corner of the baffle, and the outlet end of the vent hole points to the bend of the baffle strip on the side of the baffle.
[0015] Preferably, the condenser tube has a serpentine coil structure, the serpentine coil is connected to an external condenser, and the outer wall of the serpentine coil is in contact with the air outlet path of the cooling fan.
[0016] In summary, this application has the following beneficial effects: 1. When external airflow containing sand and dust enters the heat dissipation vent, the larger sand particles are initially blocked by a baffle. Subsequently, the airflow carrying fine dust particles passes further through the ventilation channels within the dust filter. This dust filter combines multiple filtration media, including dust mesh and dust-proof fibers, effectively intercepting tiny particles and ensuring clean air entering the cabinet, thereby guaranteeing high-performance heat dissipation of the system in harsh sandy environments.
[0017] 2. By mimicking the structure of tripe, the filtration area and meandering path are increased. Specifically, tripe has numerous folds and an uneven surface, greatly increasing its surface area for digestion and absorption. Similarly, the corrugated structure allows the filter element to have a large filtration surface area within a limited space.
[0018] 3. The vibration assembly drives the intermittent narrowing and widening of the gap between the movable and fixed plates. As the movable plate approaches the fixed plate, it applies periodic pressure to the dust filter element, causing slight deformation or compression of the filter material. This mechanical stress loosens and removes particulate matter, dust, and other contaminants adsorbed or trapped inside or on the surface of the filter element, thereby restoring its permeability and ensuring heat dissipation efficiency. This process is similar to physically beating away dust from a fabric surface, effectively improving the system's maintenance convenience and operational reliability, thus achieving a self-cleaning function to maintain the long-term performance of the filter element.

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content. Example
[0021] This invention discloses a PCS energy storage inverter cabinet, such as Figure 1 and Figure 2 As shown, it includes a cabinet body 1, a support base 2 located at the bottom of the cabinet body 1, and a door 3 located on one side of the cabinet body 1. Both opposite sides of the cabinet body 1 are provided with heat dissipation vents 4. The interior of the heat dissipation vents 4 is provided with rotatable louvers 5. A cooling fan 6 is provided inside the cabinet body 1 near the heat dissipation vents 4.
[0022] like Figure 1 and Figure 2 As shown, during power conversion, the PCS energy storage inverter generates a significant amount of heat due to power losses in its internal power devices, transformers, and capacitors. If this heat cannot be dissipated in time, it will cause the internal temperature to rise, affecting the performance, reliability, and lifespan of the devices, and may even lead to malfunctions. The heat dissipation vents 4 on both sides of the cabinet 1 and the internal cooling fan 6 constitute a forced convection cooling system. The fan draws in cooler external air, creating airflow inside the cabinet 1. This airflow passes over the surfaces of the heat-generating components, carrying away the heat generated by the components and raising the air temperature. The heated air is then exhausted from the cabinet 1 through another heat dissipation vent 4, continuously removing internal heat and maintaining the internal temperature within a safe range. Rotatable louvers 5 are an important component of the heat dissipation vents 4. The angle of the louvers 5 can be adjusted to control the flow and direction of incoming and outgoing air, achieving more precise temperature management. When the ambient temperature is low, the louvers 5 can be appropriately closed to reduce overcooling and save fan energy. When not in use or when it is necessary to block external objects, the louvers 5 can be closed or partially opened, effectively preventing dust, foreign objects, small animals, rainwater, and even some electromagnetic interference from entering the cabinet and protecting sensitive electronic components.
[0023] like Figure 2 and Figure 3As shown, a dustproof net 7 is installed on one side of the cooling fan 6, near the center of the cabinet 1. Dustproof fibers 8, made of polyester fiber, are evenly distributed on one side of the dustproof net 7. Specifically, when air flows through the dustproof net 7, larger dust particles directly contact the fibers and are physically blocked, unable to pass through the gaps between the fibers. For smaller particles that still have some mass, when the airflow changes direction and bypasses the fibers, due to their own inertia, they deviate from the airflow direction and collide with the fibers, being captured. For very small particles, they undergo Brownian motion in the airflow, randomly colliding with the fibers and being captured. This effectively prevents dust, lint, and other particulate matter from entering the cabinet 1, protecting the circuit boards and other precision electronic components from dust intrusion.
[0024] like Figure 3 As shown, a condenser pipe 9 is installed between the cooling fan 6 and the dust filter 7. The condenser pipe 9 is connected to an external condenser. When the cooling fan 6 blows hot air from inside the cabinet 1 through the serpentine coil, the refrigerant inside the coil absorbs heat from the air. This heat causes the refrigerant to evaporate from a liquid state to a gaseous state, which is an endothermic process, thus lowering the temperature of the air flowing through the coil. Furthermore, the condenser pipe 9 has a serpentine coil structure, and the serpentine design significantly increases the contact surface area and contact time between the coil and the flowing air. This winding path ensures more thorough heat exchange between the refrigerant and the air, maximizing the efficiency of heat absorption. The serpentine structure maximizes the heat transfer area, allowing the refrigerant to absorb heat from the air inside the cabinet 1 more efficiently and quickly, thereby achieving rapid and effective cooling.
[0025] like Figure 3 and Figure 4 As shown, a baffle 10 is installed inside the cabinet 1 near the heat dissipation vent 4. The baffle 10 has a zigzag cross-section and forms several V-shaped corners 11 on its side. A guide plate 12, inclined towards the heat dissipation vent 4, is provided at the bottom of the baffle 10. When an airflow carrying sand and dust attempts to enter the cabinet 1 through the heat dissipation vent 4, it first encounters the zigzag baffle 10. Due to its low inertia, the airflow can relatively easily change direction along the zigzag surface of the baffle 10 and continue flowing into the cabinet 1. However, sand particles in the sand have a large mass and inertia. When they move rapidly with the airflow, due to inertia, the sand particles cannot change direction as quickly and flexibly as the airflow. They continue to maintain their original motion trend and are therefore more likely to directly impact the V-shaped corners 11 or the zigzag surface of the baffle 10. After impacting the baffle 10, the kinetic energy of the sand particles is greatly reduced, and their speed is slowed down. Once the sand loses sufficient forward momentum, it will begin to fall under the influence of gravity and will no longer be carried by the airflow into the cabinet 1.
[0026] like Figure 3 and Figure 4 As shown, the sand particles intercepted by the baffle 10 will slide down the surface of the baffle 10 to the bottom under the action of gravity. The bottom of the baffle 10 is provided with a guide plate 12 that is inclined towards the heat dissipation vent 4. This means that the collected sand particles will be guided to slide along this inclined surface under the action of gravity and eventually be discharged from the same heat dissipation vent 4 to the outside of the cabinet 1.
[0027] like Figure 3 and Figure 4 As shown, this design achieves a "self-cleaning" or "self-exhausting" function for sand particles, preventing their accumulation inside cabinet 1. Utilizing the difference between the inertia of the sand particles and airflow, most of the incoming sand particles can be effectively separated, significantly reducing the amount of sand entering cabinet 1. Through the design of the guide plate 12, the intercepted sand particles are effectively discharged from cabinet 1, preventing their accumulation inside and thus avoiding interference with the normal operation and cleaning maintenance of the internal equipment. Sand and dust are a major killer of electronic equipment. They can wear down fan bearings, cover circuit boards causing short circuits, or hinder heat dissipation, leading to component aging. Effectively blocking sand and dust can significantly extend the lifespan of the precision equipment inside cabinet 1 and improve its stability.
[0028] like Figure 4 As shown, a vent 13 is provided at the corner 11 of the baffle 10, extending downwards through the baffle 10. A baffle strip 14 is provided on the side of the baffle 10 at the corner 11. The outlet of the vent 13 faces the bend 15 of the baffle strip 14. When an airflow carrying dust attempts to enter the vent 13, because the outlet of the vent 13 points towards the bend 15 of the baffle strip 14, the airflow must make a sharp turn to enter the vent 13. Due to their mass and inertia, dust particles cannot typically make sharp turns as flexibly as gas molecules. They tend to move along their original direction, thus colliding with the bend 15 of the baffle strip 14 and being blocked, rather than entering the vent 13. This forms a labyrinthine or deflector-type dust barrier.
[0029] like Figure 4 As shown, the presence of the vent 13 ensures pressure balance between the inside and outside, allowing necessary air exchange. This exchange helps to expel internal heat or moisture, or to introduce fresh air. By creating a tortuous airflow path and physical barrier, the likelihood of external dust entering the equipment is greatly reduced, effectively protecting the internal precision components.
[0030] like Figure 3 and Figure 5As shown, a dust filter element 16 is provided between the baffle 10 and the cooling fan 6. The dust filter element 16 includes a fixed plate 1601 and a movable plate 1602. Several longitudinal strip-shaped air holes 1603 are correspondingly provided on the fixed plate 1601 and the movable plate 1602. Several filter elements 1604 with a corrugated cross-section are provided between the fixed plate 1601 and the movable plate 1602. Adjacent filter elements 1604 form a breathable channel 1605 at the longitudinal strip-shaped air holes 1603. Spherical particle protrusions are evenly distributed on the inner surface of the filter element 1604. The particle protrusions are made of activated carbon.
[0031] like Figure 3 and Figure 5 As shown, after air enters, it no longer flows in a straight line, but is forced to meander along these corrugated air passages 1605. This tortuous path increases the chance of dust particles coming into contact with the filter material. When the airflow direction changes, due to inertia, dust particles are more likely to break away from the airflow and collide with the filter surface and be captured.
[0032] like Figure 3 and Figure 5 As shown, larger dust particles, when the airflow changes direction through the corrugated channel, cannot make a sharp turn due to inertia and will directly collide with the filter surface and be trapped. Although the particle diameter is smaller than the channel width, when its centerline passes within a particle radius of the filter fiber surface, it will be captured by the fiber surface. For extremely small micron and submicron particles (such as smoke and bacteria), they undergo Brownian motion in the air and randomly collide with the filter surface and are captured.
[0033] like Figure 3 and Figure 5 As shown, the spherical particle protrusions further increase the roughness and microstructure of the filter surface, providing more attachment points and capture sites for dust particles. They may also create tiny eddies in the airflow, making it easier to capture smaller particles. Activated carbon has a highly developed pore structure and a huge specific surface area, which gives it a strong adsorption capacity. Activated carbon can adsorb fine dust and odor molecules in the air through weak interaction forces such as van der Waals forces. This means that it can not only intercept but also "capture" those extremely small particles that might penetrate physical barriers.
[0034] like Figure 3 and Figure 5 As shown, this design, in summary, mimics the organism of a tripe; by increasing surface area and creating complex pathways to efficiently process substances, it combines mechanical filtration, inertial capture, and chemical adsorption (especially for fine particles and odors) to achieve a more thorough air purification effect.
[0035] like Figure 5 As shown, the fixed plate 1601 is fixed inside the cabinet 1, and the movable plate 1602 is a slidable structure inside the cabinet 1. A vibration assembly for driving the movable plate 1602 is provided on the top of the cabinet 1. This vibration assembly drives the movable plate 1602, causing the distance between the movable plate 1602 and the fixed plate 1601 to intermittently decrease and increase, achieving a self-cleaning effect. When the vibration assembly drives the movable plate 1602 closer to the fixed plate 1601, the movable plate 1602 applies pressure to the filter element 1604. This squeezing action causes slight deformation or compression of the material of the filter element 1604. During the squeezing deformation process, particles, dust, or other contaminants adsorbed / trapped inside or on the surface of the filter element 1604 are loosened and peeled off due to physical forces. This is similar to patting or shaking a carpet to remove dust.
[0036] like Figure 5 As shown, the vibration component intermittently reduces and expands the gap between the movable plate 1602 and the fixed plate 1601. When the gap expands, the pressure on the filter element 1604 is released, and the filter element 1604 returns to its original shape. At this time, contaminants that have detached from the surface of the filter element 1604 can be discharged from the bottom of the filtration system under the action of gravity or other auxiliary airflow / water flow.
[0037] The vibration assembly includes a motor and a transmission mechanism. The motor drives the movable plate 1602 to reciprocate along the slide rail of the cabinet 1 via the transmission mechanism. The distance between the movable plate 1602 and the fixed plate 1601 changes periodically with the reciprocating motion. Specifically, the transmission mechanism includes an eccentric wheel and a connecting rod. The eccentric wheel is fixedly connected to the output shaft of the motor, one end of the connecting rod is hinged to the eccentric wheel, and the other end is hinged to the sliding bracket of the movable plate 1602.
[0038] like Figure 5 As shown, in short, it involves physical vibration and repeated compression and relaxation of the filter element, like patting or shaking, to forcibly loosen, peel off and discharge the impurities attached to the filter element, thereby achieving self-cleaning of the filter element.
[0039] like Figure 5 As shown, by regularly removing the blockages from filter element 1604, the filtration system can maintain high filtration efficiency and stable flow rate, avoiding performance degradation caused by filter element clogging. Timely removal of contaminants can effectively prevent excessive clogging and material fatigue of filter element 1604, thereby significantly extending the service life of filter element 1604, reducing replacement frequency, and lowering consumable costs.
[0040] like Figure 5As shown, the filter element 1604 is made of non-woven fabric, and a wear-resistant layer is provided on the outer surface of the non-woven fabric. Corrugated reset positioning strips 1606 are arranged from top to bottom between the non-woven fabric interlayer and the wear-resistant layer of the filter element 1604. The corrugated reset positioning strips 1606 essentially function as springs. When the movable plate 1602 applies pressure to the filter element 1604 during the self-cleaning process, these corrugated strips undergo elastic deformation. Specifically, the corrugation amplitude of the reset positioning strips 1606 is the same as the original corrugation amplitude of the filter element 1604, and the reset positioning strips 1606 are made of metal wire or high-strength elastic plastic.
[0041] like Figure 5 As shown, these reset positioning strips 1606 are disposed between the non-woven fabric interlayer and the abrasion-resistant layer, making them part of the filter element 1604 structure. When the external pressure is released, the corrugated strips will return to their original corrugated shape due to their inherent elastic properties. This restoring force will act in the opposite direction on the movable plate 1602, or push the filter element 1604 itself back to its initial position. Since the filter element 1604 is associated with the movable plate 1602, the self-resetting of the filter element 1604 will also indirectly or directly help the movable plate 1602 return to its preset open or ready position, thereby completing one cleaning cycle and preparing for the next cycle.
[0042] Working principle: For PCS energy storage inverter cabinets deployed in desert environments, the heat dissipation system is designed to maintain efficient and stable operation under extreme conditions.
[0043] During rack operation, internal heat is efficiently exchanged through the combined action of cooling fan 6 and condenser pipe 9. External air is introduced into the rack for heat dissipation, a process accompanied by strict dust and sand protection measures.
[0044] Specifically, when external airflow containing sand and dust enters the heat dissipation vent 4, the baffle 10 first physically blocks the larger sand particles. Subsequently, the airflow carrying fine dust further passes through the ventilation channel 1605 inside the dust filter element 16. This dust filter element 16 combines multiple filtration media such as dustproof mesh 7 and dustproof fiber 8, which can effectively intercept tiny particles, ensuring clean air entering the cabinet, thereby guaranteeing high-performance heat dissipation of the system in harsh sandy environments.
[0045] Furthermore, this heat dissipation system integrates a self-cleaning function to maintain the long-term performance of the filter element. A vibration assembly drives the intermittent narrowing and widening of the gap between the movable plate 1602 and the fixed plate 1601. When the movable plate 1602 approaches the fixed plate 1601, it applies periodic pressure to the dust filter element 16, causing slight deformation or compression of the filter material. This mechanical stress loosens and removes contaminants such as particles and dust adsorbed or trapped inside or on the surface of the filter element, thereby restoring the filter element's permeability and ensuring heat dissipation efficiency. This process is similar to removing dust from the surface of fabric by physically beating it, effectively improving the system's ease of maintenance and operational reliability.
[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
