Description

Technical Field

[0001] This invention relates to the field of distributed energy storage cabinet technology, specifically to a high-temperature resistant control cabinet for distributed energy storage. Background Technology

[0002] Distributed energy storage systems are used for the coordinated optimization of power supply in various regions. They can improve power supply reliability and power quality through peak shaving and valley filling, frequency regulation, and renewable energy integration. Controlling the entire distributed energy storage system requires numerous energy storage control cabinets to house the energy storage batteries and various controllers and other electrical components. During the charging and discharging processes of the energy storage batteries and other electrical components inside the control cabinet, heat is generated. Therefore, heat dissipation is necessary inside the control cabinet to ensure the normal operation of these electrical components. Existing heat dissipation components for energy storage control cabinets typically use electric fans to accelerate air circulation between the inside and outside of the cabinet. However, the design of this existing heat dissipation airflow is relatively simple—a simple open airflow path. The external air entering the cabinet flows irregularly within the cabinet, causing some of the air entering the cabinet to be forced out of the cabinet through the exhaust vents before it can reach the electrical components. This results in low heat dissipation efficiency and poor cooling effect per unit of energy consumption. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a high-temperature resistant control cabinet for distributed energy storage, so as to solve the problems of slow heat dissipation efficiency and poor cooling effect per unit energy consumption of the existing control cabinet.

[0004] To solve the above-mentioned technical problems, a basic solution adopted by the present invention is: to provide a high-temperature resistant control cabinet for distributed energy storage, including a cabinet body, multiple support plates for installing electrical components disposed within the cabinet body, a cover covering each electrical component, and an air extraction assembly for suction of the inner cavity of the cover covering; the cabinet body is enclosed on all four sides, a support member is provided at the bottom of the cabinet body, and the bottom plate of the cabinet body is provided with several air inlets; the support plates are horizontally arranged, and their periphery is fixedly connected to the inner wall of the cabinet body; multiple support plates are arranged sequentially at intervals; the area of ​​the support plate covered by the cover covering is provided with several ventilation channels that connect the upper and lower parts of the support plate. The cover is an inverted U-shaped cavity with an opening at the bottom. The lower end of the cover is sealed to the upper surface of the support plate along its circumference, covering the electrical components on the support plate. The suction assembly includes a first exhaust fan, a main exhaust pipe, and multiple exhaust branch pipes corresponding to the cover. The first exhaust fan is located at the top of the cabinet, and its outlet is connected to the external space of the cabinet. The main exhaust pipe is located inside the cabinet, with one end sealed to the air inlet of the first exhaust fan and the other end closed. The two ends of the exhaust branch pipes are sealed to the inner cavity of the cover and the inner cavity of the main exhaust pipe, respectively.

[0005] In the above basic scheme, when the first exhaust fan is running, it draws air from the inner cavity of each cover through the main exhaust pipe and then through each branch exhaust pipe. Air from outside the cabinet enters the inner cavity through the air inlet at the bottom of the cabinet and then flows through the ventilation channels on each support plate into the inner cavity of each cover. The air entering the inner cavity of each cover flows over the surface of the electrical components under the suction of the first exhaust fan, carrying away the heat generated during operation and achieving the purpose of cooling the electrical components. Compared with the open airflow cooling method used in existing technologies, this scheme uses independent air ducts to cool each electrical component. The airflow within each cover can quickly flow over the surface of each electrical component, carrying away the heat generated. Therefore, this scheme has a higher heat dissipation efficiency per unit energy consumption of the first exhaust fan.

[0006] Furthermore, a first through hole is provided on one side wall of the cover, connecting the inner and outer spaces of the cover. One end of the suction branch pipe is sealed and connected to the first through hole, and the other end of the suction branch pipe is sealed and connected to the inner cavity of the suction main pipe. A slide is vertically provided inside the side wall of the cover where the first through hole is located. The lower end of the slide is connected to the first through hole, and the upper end of the slide is a closed end. A sliding column is slidably connected inside the slide. The upper end of the sliding column is located inside the slide, and the lower end of the sliding column extends out of the slide. A tension spring is provided between the sliding column and the closed end of the slide rail. The lower end of the tension spring is connected to the sliding column, and the upper end of the tension spring is connected to the closed end of the slide rail. A vertical groove is vertically provided inside the side wall of the cover. The upper end of the vertical groove communicates with the first through hole. A vertical slide plate is slidably connected inside the vertical groove. The upper end of the vertical slide plate is fixedly connected to the lower end of the sliding column. Under normal temperature conditions, the tension spring forces the lower end of the sliding column to approach the open end of the slide rail, so that the vertical slide plate blocks the first through hole.

[0007] When the electrical components operate, causing the temperature inside the cover to rise, the temperature inside the slide rail also rises, leading to increased air pressure. This increased air pressure forces the sliding column downwards, pushing the vertical sliding plate down and opening the first through-hole. The higher the heat generated by the electrical components, the higher the temperature inside the cover, the greater the air pressure in the slide rail, the longer the sliding column moves downwards, and the larger the flow channel of the first through-hole becomes. This results in a larger airflow rate through the cover's interior under the suction of the exhaust fan, and faster heat dissipation for the electrical components within the cover. Conversely, the lower the heat generated by an electrical component within a cover, the smaller the flow channel of the corresponding first through-hole, and consequently, the smaller the airflow rate through that cover's interior. This design allows for the rational distribution of the total air output by the exhaust fan based on the heat generated by the electrical components within each cover, improving the exhaust fan's airflow utilization rate.

[0008] Furthermore, a transverse sliding groove is provided in the bearing plate corresponding to the coverage area of ​​the cover, and a transverse sliding plate and a spring are provided in the transverse sliding groove. The transverse sliding plate is slidably connected to the transverse sliding track. One end of the spring is fixedly connected to the transverse sliding plate, and the other end of the spring is connected to the inner wall of the transverse sliding groove. The ventilation channel includes a first air hole that vertically penetrates the bearing plate and a second air hole that vertically penetrates the transverse sliding plate.

[0009] The inner cavity of the cover is provided with a bimetallic strip made of two metals with different coefficients of thermal expansion bonded together. The bimetallic strip is horizontally arranged, with one end fixedly connected to the inner wall of the cover and the other end being a free end. A stop bar is vertically arranged at the free end of the bimetallic strip, and the upper end of the stop bar is fixedly connected to the bimetallic strip. A sliding hole is vertically arranged on the support plate to slide with the stop bar. The lower end of the stop bar extends into the transverse sliding groove through the sliding hole. The end face of the transverse sliding plate away from the spring contacts the lower outer wall of the stop bar, so that the spring is in a compressed state and the first air hole and the second air hole are aligned, thereby opening the ventilation channel.

[0010] When the heat generated by the electrical components is too high to be dissipated in time, causing the components to burn at high temperatures, the high temperature causes the bimetallic strip to deform, causing the free end of the bimetallic strip to tilt upwards and drive the stop lever to slide away from the transverse groove. The transverse slide plate in the transverse groove loses the obstruction of the stop lever, and under the elastic force of the compressed spring, the transverse slide plate slides, causing the first vent and the second vent to be misaligned to close the ventilation channel. Air cannot enter the inner cavity of the cover, and the lack of oxygen in the inner cavity of the cover forces the electrical components to stop burning.

[0011] Furthermore, the suction assembly also includes a second exhaust fan disposed on the top of the cabinet. The air inlet of the second exhaust fan is connected to the inner cavity of the cabinet, and the air outlet of the second exhaust fan is connected to the external space of the cabinet. Several ventilation holes are provided in the area of ​​the support plate not covered by the cover to allow the support plate to pass through from top to bottom.

[0012] Furthermore, a relay corresponding to the cover is installed inside the cabinet. The electrical components inside the cover are electrically connected to the external wall wiring through the relay. When the bimetallic strip inside the cover deforms and causes the stop bar to slide away from the transverse groove, the corresponding relay disconnects the electrical components inside the cover from the external wiring.

[0013] Furthermore, doors are installed on the side walls of the cabinet.

[0014] Furthermore, the cover is made of aluminum.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] 1. This solution uses independent air ducts to dissipate heat from each electrical component, so that each cover can generate airflow that fully contacts and flows rapidly with the surface of the electrical component. Under the unit energy consumption of the first exhaust fan, the heat dissipation efficiency of this solution is higher.

[0017] 2. This solution can rationally distribute the total amount of air drawn by the exhaust fan according to the heat generated by the electrical components in each cover, thereby improving the air volume and energy efficiency of the exhaust fan.

[0018] 3. This solution improves the cooling effect by setting up a first exhaust fan and a second exhaust fan to dissipate heat and cool the internal and external spaces of the cover respectively.

[0019] 4. Each cover component in this solution has an independent flame-retardant structure. When a certain electrical component burns, it is isolated and disconnected from the outside, without affecting the operation of other electrical components. Attached Figure Description

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0030] This embodiment provides a high-temperature resistant control cabinet for distributed energy storage, such as... Figures 1-5 As shown, the system includes a cabinet 10, a support plate 20 for installing electrical components 50 disposed within the cabinet 10, a cover 30 covering each electrical component 50, and an air extraction assembly for suctioning the inner cavity of the cover 30. The cabinet 10 is enclosed on all sides, and a support member 101 is provided at the bottom of the cabinet 10. The bottom plate of the cabinet 10 is provided with several air inlets 102 for air from outside the cabinet 10 to enter the internal space of the cabinet 10. A door 60 is provided on one side wall of the cabinet 10 for opening or closing the inner cavity of the cabinet 10. The support plate 20 is horizontally arranged and its periphery is fixedly connected to the inner wall of the cabinet 10. In this embodiment, there are 3 support plates 20. In other feasible embodiments, other numbers of support plates 20 can be set according to the size of the cabinet 10 and the needs. In this embodiment, the 3 support plates 20 are arranged vertically and alternately.

[0031] The cover 30 is made of aluminum and has good thermal conductivity. The cover 30 is an inverted U-shaped cavity with an opening at the bottom. The lower end of the cover 30 is sealed to the upper surface of the support plate 20 along the circumference, covering the electrical component 50 on the support plate 20. The cover 30 can be detachably connected to the support plate 20 by screws. The area of ​​the support plate 20 covered by the cover 30 is provided with several ventilation channels 206 that run vertically through the support plate 20. The area of ​​the support plate 20 not covered by the cover 30 is provided with several ventilation holes 201 that run vertically through the support plate 20. A transverse sliding groove 202 is provided inside the support plate 20 covered by the cover 30. A transverse sliding plate 203 and a spring 204 are provided inside the transverse sliding groove 202. The transverse sliding plate 203 is slidably connected to the transverse sliding track 301. One end of the spring 204 is fixedly connected to the transverse sliding plate 203, and the other end of the spring 204 is connected to the inner wall of the transverse sliding groove 202. The ventilation channel 206 includes a first air hole 2061 that runs vertically through the support plate 20 and a second air hole 2062 that runs vertically through the transverse sliding plate 203. The first air hole 2061 is intersecting and communicating with the transverse sliding groove 202.

[0032] The inner cavity of the cover 30 is provided with a bimetallic strip 307 made of two metals with different coefficients of thermal expansion bonded together. The bimetallic strip 307 is horizontally arranged, with one end of the bimetallic strip 307 fixedly connected to the inner wall of the cover 30, and the other end of the bimetallic strip 307 being a free end. A stop bar 308 is vertically arranged at the free end of the bimetallic strip 307, and the upper end of the stop bar 308 is fixedly connected to the bimetallic strip 307. A vertically sliding joint is provided on the support plate 20 that slides against the stop bar 308. A sliding hole 205 is provided for dynamic engagement, which connects the transverse sliding groove 202 to the upper space of the support plate 20. The lower end of the stop rod 308 extends into the transverse sliding groove 202 through the sliding hole 205. The end face of the transverse sliding plate 203 away from the spring 204 contacts the lower outer wall of the stop rod 308, causing the spring 204 to be in a compressed state and aligning the first air hole 2061 with the second air hole 2062, thereby opening the ventilation channel 206. A relay corresponding to the cover 30 is provided inside the cabinet 10. The electrical components 50 inside the cover 30 are electrically connected to the external wall wiring through the relay. When the thermoplastic bimetallic strip 307 inside the cover 30 deforms, causing the stop rod 308 to slide away from the transverse sliding groove 202, the corresponding relay disconnects the electrical components 50 inside the cover 30 from the external wiring.

[0033] The suction assembly includes a first exhaust fan 41, a main exhaust pipe 43, and multiple exhaust branch pipes 44 corresponding to the cover 30. The first exhaust fan 41 and the second exhaust fan 42 are both fixedly connected to the top of the cabinet 10. The air inlets of the first exhaust fan and the second exhaust fan 42 are connected to the inner cavity of the cabinet 10, and the air outlets of the first exhaust fan and the second exhaust fan 42 are connected to the external space of the cabinet 10. The main exhaust pipe 43 is located inside the cabinet 10 and is vertically arranged. The main exhaust pipe 43 passes through each support plate 20 in sequence. The upper end of the main exhaust pipe 43 is sealed and connected to the air inlet of the first exhaust fan 41, and the lower end of the main exhaust pipe 43 is closed.

[0034] A first through hole 306 is provided on one side wall of the cover 30, connecting the inner and outer spaces of the cover 30. The first through hole 306 is horizontally arranged. One end of the suction branch pipe 44 is sealed and connected to the first through hole 306, and the other end of the suction branch pipe 44 is sealed and connected to the inner cavity of the suction main pipe 43. A slide rail 301 is vertically arranged inside the side wall of the cover 30 where the first through hole 306 is located. The lower end of the slide rail 301 is connected to the first through hole 306. The upper end of the slide rail 301 is closed. A sliding column 302 is slidably connected within the slide rail 301. The diameter of the sliding column 302 is smaller than the diameter of the first through hole 306. The upper end of the sliding column 302 is located inside the slide rail 301, and the lower end of the sliding column 302 extends outside the slide rail 301. A tension spring 303 is provided between the sliding column 302 and the closed end of the slide rail 301. The lower end of the tension spring 303 is connected to the sliding column 302, and the upper end of the tension spring 303... A vertical groove 304 is vertically provided inside the side wall of the cover 30, connected to the closed end of the slide 301. The upper end of the vertical groove 304 communicates with the first through hole 306. A vertical slide plate 305 is slidably connected inside the vertical groove 304. The horizontal and vertical dimensions of the vertical slide plate 305 are both larger than the diameter of the first through hole 306. The gap between the vertical slide plate 305 and the vertical groove 304 allows the vertical slide plate 305 to slide freely up and down inside the vertical groove 304. The upper end of the vertical slide plate 305 is fixedly connected to the lower end of the slide column 302. Under normal temperature conditions, the tension spring 303 forces the lower end of the slide column 302 to approach the open end of the slide 301, causing the vertical slide plate 305 to block the first through hole 306. The normal temperature conditions refer to the low temperature generated by the electrical component 50 inside the cover 30, which is insufficient to raise the internal air pressure of the slide 301 to force the slide column 302 to slide downward.

[0035] In this scheme, when the first exhaust fan 41 is running, the first exhaust fan 41 draws air from the inner cavity of each cover 30 through the main exhaust pipe 43 and then through each exhaust branch pipe 44. The air outside the cabinet 10 enters the inner cavity of the cabinet 10 through the air inlet 102 at the bottom of the cabinet 10 and then enters the inner cavity of each cover 30 through the ventilation channel 206 on each support plate 20. The gas entering the inner cavity of each cover 30 flows over the surface of the electrical component 50 under the suction of the first exhaust fan 41, carrying away the heat generated by the electrical component 50 when it is working, thereby achieving the purpose of cooling the electrical component 50. When the second exhaust fan 42 is running, it draws air from the space outside the cover 30 inside the cabinet 10 to enhance the air circulation in the space outside the cover 30, thereby cooling the cover 30 externally.

[0036] When the electrical component 50 operates, causing the temperature inside the cover 30 to rise, the temperature inside the slide rail 301 also rises, and the air pressure increases accordingly. The increased air pressure inside the slide rail 301 forces the slide column 302 to slide downward, pushing the vertical slide plate 305 down to open the first through hole 306. Under the suction of the first exhaust fan 41, the airflow flows through the inside of the cover 30 to dissipate heat from the electrical component 50 inside the cover 30. The higher the heat generated by the electrical component 50, the higher the temperature of the inside of the cover 30 and the side wall, the greater the air pressure inside the slide rail 301, the longer the slide column 302 moves downward, and the further the vertical slide plate 305 moves downward, the larger the flow channel of the first through hole 306 becomes. Under the suction of the exhaust fan, the airflow through the inside of the cover 30 is greater, and the heat dissipation efficiency of the electrical component 50 inside the cover 30 is also faster. Conversely, the less heat generated by the electrical component 50 within a certain cover 30, the smaller the flow channel of the first through hole 306 corresponding to that cover 30, and consequently the smaller the airflow through the inner cavity of that cover 30. Through the above scheme, the total amount of air drawn by the exhaust fan can be reasonably distributed according to the heat generated by the electrical component 50 within each cover 30, thereby improving the airflow utilization rate of the exhaust fan.

[0037] When the heat generated by the electrical component 50 is too high to be dissipated in time, causing the electrical component 50 to burn at high temperature, the high temperature causes the bimetallic strip 307 to deform, causing the free end of the bimetallic strip 307 to tilt upwards, which drives the stop lever 308 to slide away from the transverse slide groove 202. The transverse slide plate 203 in the transverse slide groove 202 loses the obstruction of the stop lever 308. Under the elastic force of the compressed spring 204, the transverse slide plate 203 slides, causing the first vent 2061 and the second vent 2062 to be misaligned, thereby closing the ventilation channel 206. Air cannot enter the inner cavity of the cover 30. The lack of oxygen in the inner cavity of the cover 30 forces the electrical component 50 to stop burning. At the same time, the corresponding relay disconnects the electrical component 50 in the cover 30 from the external circuit to prevent the temperature of the electrical component 50 from continuing to rise.

[0038] Compared with the prior art, the present invention has at least the following beneficial effects:

[0039] 1. This solution uses independent air ducts to dissipate heat from each electrical component 50, so that each cover 30 can generate airflow that is in full contact with the surface of the electrical component 50 and flows rapidly. Under the unit energy consumption of the first exhaust fan 41, the heat dissipation efficiency of this solution is higher.

[0040] 2. This solution can reasonably distribute the air volume generated by the first exhaust fan 41 according to the heat generated by the electrical components 50 in each cover 30, thereby improving the energy utilization rate of the first exhaust fan 41.

[0041] 3. This solution improves the cooling effect by setting a first exhaust fan 41 and a second exhaust fan 42 to dissipate heat and cool the internal and external spaces of the cover 30, respectively.

[0042] 4. Each cover 30 in this solution has an independent fire-resistant structure. When a certain electrical component burns, it is isolated and disconnected from the outside, without affecting the operation of other electrical components 50.

[0043] The above are merely embodiments of the present invention, and common knowledge regarding specific structures and characteristics in the solutions is not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
