Description

Technical Field

[0001] This invention relates to the field of new energy equipment technology, specifically a cooling mechanism for a new energy storage tank. Background Technology

[0002] With the rapid development of the new energy industry, energy storage equipment has become a key component in building a new energy system. The core function of this type of equipment is to achieve efficient energy conversion, safe storage, and flexible release, thereby effectively balancing energy supply and demand fluctuations and improving the overall system utilization efficiency. Among various energy storage technologies, battery energy storage has become a widely used form due to its compact structure and high energy density. Its working principle involves converting electrical energy into chemical energy through chemical batteries for storage, and releasing it in reverse when needed. However, batteries inevitably generate significant heat during charging and discharging; therefore, equipping them with effective heat dissipation equipment is essential for ensuring their safe and long-term operation.

[0003] In existing technologies, equipping energy storage boxes with dedicated cabinet air conditioners is a common temperature control solution. This equipment is usually installed on the side wall of the box, and its core working mechanism is based on the principle of compression refrigeration cycle. The refrigerant inside the cabinet air conditioner absorbs heat from the air inside the box and vaporizes in the evaporator. Then, it is pressurized by the compressor and sent to the condenser, where it releases heat to the external environment and then re-liquefies. This cycle is repeated to continuously reduce the temperature inside the energy storage box and maintain it within the set target range, thereby achieving active cooling of core components such as batteries.

[0004] In typical applications such as solar power generation, energy storage boxes are often deployed near photovoltaic arrays for system integration and ease of operation and maintenance. In summer, when the boxes are directly exposed to strong sunlight and the external ambient temperature is high, relying solely on the side-wall cabinet air conditioner for cooling will affect the efficiency of its condenser in dissipating heat to the high-temperature environment. This significantly increases the energy consumption required to maintain the internal temperature, placing a load on the equipment. Furthermore, the limited coverage of the cold air radiated from its outlet may affect the uniformity of the internal temperature. In winter, when the outside temperature drops, natural or forced air cooling could be used to save energy. However, to maintain a fixed temperature setpoint, the cabinet air conditioner often still consumes electricity to drive the compressor for cooling, failing to fully utilize the free cooling source of the environment and resulting in unnecessary energy consumption. Therefore, this invention proposes a cooling mechanism for a new energy storage box to solve the above problems. Summary of the Invention

The fixed sunshade is L-shaped, and the end of the fixed sunshade away from the guide block is fixedly connected to the upper surface of the cover.

[0007] Preferably, two fixed frames are symmetrically fixedly connected to the side of the housing near the upper surface of the cover. Each fixed frame has a limit groove. A guide frame is fixedly connected to the top of the opposite sides of the two fixed frames. A movable frame is slidably engaged on the upper side of the guide frame.

[0008] Preferably, the drive assembly includes a motor fixedly mounted on one of the fixed frames, a drive shaft fixedly connected to the output end of the motor, a take-up reel fixedly sleeved to one end of the drive shaft, a drive sprocket fixedly sleeved to the other end of the drive shaft, a driven sprocket meshing with the drive sprocket via a chain, a driven shaft fixedly connected to the driven sprocket, another take-up reel fixedly connected to the driven shaft, and three transmission wheels that are driven by friction with each take-up reel via wire rope.

[0009] Preferably, the guide frame is fixedly connected to both ends of its length direction with a lower limit pin, and the movable frame is fixedly connected to both ends of its length direction with an upper limit pin. The two transmission wheels are rotatably connected to the guide frame through the lower limit pin, and the other transmission wheel is rotatably connected to the limit block through a connecting pin. The limit block is slidably installed in the limit groove, and the upper surface of the limit block is fixedly connected to the lower surface of the guide frame near the motor end through a first spring.

[0010] Preferably, both the drive shaft and the driven shaft are rotatably connected to the fixed frame via a support base. One output end of the wire rope passes around two transmission wheels near the motor and is fixedly connected to an upper limit pin of the moving frame away from the motor. The other output end of the wire rope passes around another transmission wheel away from the motor and is fixedly connected to another upper limit pin of the moving frame near the motor.

[0011] Preferably, the transmission assembly includes a drive block fixedly installed on the bottom of one of the movable frames near the motor end, a driven block slidably connected to the bottom of the drive block, a transmission rod fixedly connected to the driven block, a transmission block fixedly connected to the transmission rod, two sliding pins slidably connected to the transmission block, a connecting rod fixedly connected to the sliding pins, and several connecting blocks rotatably connected to the connecting rod.

[0012] Preferably, the top of the drive block is fixedly connected to the movable frame, the bottom of the drive block is slidably connected to the inclined surface at the top of the driven block through an inclined surface, the bottom of the driven block is fixedly connected to the top of the transmission rod, the bottom end of the transmission rod passes through the support frame and is fixedly connected to one side of the transmission block, and the top of the transmission rod is fixedly connected to the support frame through a second spring.

[0013] Preferably, a set of guide holes is provided on the other side of the transmission block, and each guide hole is slidably connected to one of the sliding pins. Four fixed seats are fixedly connected to both sides of the connecting frame along the height direction of the box. A fixed plate is fixedly connected between the two middle fixed seats.

The wind deflector is fixedly sleeved on the connecting shaft, and the connecting shaft is rotatably sleeved in the fixed seat.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention, by incorporating temperature sensors and controllers, intelligently activates different levels of heat dissipation measures based on the actual temperature inside the energy storage tank. When the temperature is low, heat dissipation primarily relies on natural ventilation from the tank structure; when the temperature rises, the fan automatically activates to enhance airflow; only under conditions of high and continuous heat generation will the cabinet air conditioner, movable sunshade, and wind deflector be activated in conjunction with the system. This tiered response mechanism ensures that the high-power cabinet air conditioner does not run continuously but is activated only when truly needed, while also fully utilizing ambient cool air for air cooling. This effectively reduces the energy consumption of the cooling system itself and avoids energy waste caused by excessive reliance on air conditioning during winter or cooler seasons.

[0016] The ingenious design of the drive and transmission components in this invention allows the activation of the cabinet air conditioner to simultaneously trigger the unfolding of the sunshade and the opening and closing of the wind deflector. When forced cooling is required, the movable sunshade automatically extends to both sides, increasing the shading area and directly reducing the radiant heating of the cabinet by sunlight, thus lowering the heat load on the cabinet at its source. Simultaneously, the wind deflector changes from a closed V-shape to a parallel state, significantly increasing the air inlet area and allowing the fan to draw in more outside air, greatly enhancing the air-cooling effect. The synergistic operation of sunshade, air cooling, and air conditioning improves the limited heat dissipation efficiency of a single cabinet air conditioner in high-temperature environments, enhancing the overall cooling capacity and temperature uniformity of the energy storage unit during hot seasons.

[0019] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1 to 10This invention provides a technical solution: a cooling mechanism for a new energy storage box, comprising: a box body 1, which serves as the main body of the entire device; a cabinet air conditioner 2 is embedded and fixedly installed on one side of the box body 1 along its length; a controller 3 is fixedly installed on one side of the cabinet air conditioner 2, which controls the cabinet air conditioner 2 to regulate the internal temperature of the box body 1; a connecting frame 4 is fixedly connected to the other side of the box body 1 along its length; one side of the connecting frame 4 is fixedly connected to one side of a cover 5; and several dust-blocking mesh plates 6 are fixedly installed on the other side of the cover 5, arranged in a linear array along the height direction of the box body 1. An air outlet mesh is installed on the top of one side of the cabinet air conditioner 2, so that the air inside and outside the cabinet 1 can circulate and cool down its interior. A support frame 7 is fixedly connected to the other side of the connecting frame 4. Several sets of baffles 8 are arranged in a linear array along the height direction of the cabinet 1 between the connecting frame 4 and the support frame 7. Each set of baffles 8 can be rotated relative to each other, and several air holes 9 are opened on its surface. Through the several air holes 9, the outside air can enter the interior of the cabinet 1. The cabinet also includes a transmission component, which is connected to several sets of baffles 8 and is used to drive each set of baffles 8 to rotate relative to each other to achieve opening and closing. A bracket 14 is provided on the side of the support frame 7 away from the connecting frame 4. The top of the bracket 14 is fixedly connected to the inner wall of the box 1. A fan 15 is fixedly installed at the bottom of the bracket 14, and the bracket 14 provides fixed support for the fan 15. A temperature sensor 16 is fixedly installed in the middle of the bracket 14. The temperature sensor 16 is used to monitor the internal temperature of the box 1. A fixed sunshade 10 is fixedly installed on the upper side of the box 1. A movable sunshade 11 is symmetrically arranged on the lower side of the fixed sunshade 10. There is a pair of movable sunshades 11. The two movable sunshades 11 can move relative to each other along the width direction of the fixed sunshade 10. A guide groove 12 is opened at one end of the movable sunshade 11. The guide groove 12 is slidably connected to the guide block 13 fixed on the fixed sunshade 10. The sliding connection between the guide groove 12 and the guide block 13 improves the movement stability between the movable sunshade 11 and the fixed sunshade 10.

[0021] It also includes a drive assembly, which is connected to the other end of the two movable sunshades 11 and is used to drive the two movable sunshades 11 to slide relative to each other along the lower surface of the fixed sunshade 10 to expand the shading range. The drive assembly is connected to the transmission assembly.

[0022] In the initial state, each set of wind deflectors 8 is closed and forms a V-shape. Simultaneously, most of the two movable sunshades 11 retract into the fixed sunshade plate 10. The temperature sensor 16 is electrically connected to the controller 3. When the detected temperature is below the first temperature threshold, the control circuit does not start the fan 15. When the detected temperature is above the first temperature threshold but below the second temperature threshold, the control circuit only starts the fan 15. When the detected temperature is above the second temperature threshold, the control circuit simultaneously starts the cooling fan and the cabinet air conditioner 2, indirectly controlling the operation of the drive components. During use, the temperature inside the enclosure 1 is monitored by the temperature sensor 16. When the energy storage box first starts working, it generates a small amount of heat. At this time, the internal temperature of the box 1 does not reach the first temperature threshold. Only through the cooperation of the dust baffle 6 and the several air holes 9 on the baffle 8 can outside air enter the box 1, remove the heat, and allow the heat to flow out through the air outlet, thus achieving cooling of the inside of the box 1. After the box 1 has been working for a period of time, the heat inside the box 1 cannot be quickly dissipated by natural air circulation alone. Therefore, under the monitoring of the temperature sensor 16, when the temperature is higher than the first temperature threshold but lower than the second temperature threshold, the controller 3 will control the fan 15 to start. At this time, under the suction action of the fan 15, a large amount of external air passes through the several air holes 9 opened on the dust baffle 6 and the wind baffle 8 and enters the interior of the housing 1, thereby carrying away its internal heat and flowing out from the exhaust screen, thus achieving cooling and reducing energy consumption. When the housing 1 continues to work, the internal components continue to generate heat, and due to the obstruction of the wind baffle 8, the fan 15 itself also generates heat, so the temperature will continue to rise. In addition, if the external ambient temperature is high and the detected temperature exceeds the second temperature threshold, the controller 3 will turn on the cabinet air conditioner 2 and drive the components to work, further cooling the cabinet air conditioner 2. The interior of the enclosure 1 is cooled down, while the drive assembly drives the two movable sunshades 11 to extend outwards from the fixed sunshade 10, expanding the shading area and preventing the enclosure 1 from being directly exposed to the sun, thus reducing the impact of the external environment on the temperature of the enclosure 1. At the same time, with the cooperation of the transmission assembly, each set of wind deflectors 8 will rotate in opposite directions, and the two wind deflectors 8 will change from the original V-shape to two parallel wind deflectors 8. Then, under the high-speed rotation of the fan 15, the air intake volume will reach the maximum, improving the air cooling efficiency and achieving efficient cooling and heat dissipation. When the temperature drops, the controller 3 indirectly controls the reset of each component, which facilitates flexible adjustment later and ultimately reduces energy consumption.

[0023] Temperature sensor 16 is electrically connected to controller 3. Controller 3 is electrically connected to cabinet air conditioner 2 and fan 15. Fixed sunshade 10 is L-shaped and is fixedly installed on the top of cabinet 1 to initially reduce the impact of the external environment on cabinet 1. The end of fixed sunshade 10 away from guide block 13 is fixedly connected to the upper surface of cover 5.

[0024] Two fixed brackets 17 are symmetrically fixedly connected to the upper surface of the housing 1 near the cover 5. Each fixed bracket 17 has a limit groove 18. A guide bracket 19 is fixedly connected to the top of the opposite side of the two fixed brackets 17. The guide bracket 19 is parallel to the housing 1 along the length direction. A movable bracket 20 is slidably engaged on the upper side of the guide bracket 19. The guide bracket 19 guides and limits the movable bracket 20.

[0025] The drive assembly includes a motor 21, made of stainless steel, fixedly mounted on one of the fixed frames 17, electrically connected to the controller 3, a drive shaft 22 fixedly connected to the output end of the motor 21, a take-up reel 23 fixedly sleeved at one end of the drive shaft 22, a drive sprocket 24 fixedly sleeved at the other end of the drive shaft 22, a driven sprocket 26 meshing with the drive sprocket 24 via a chain 25, a tensioning wheel that can be installed between the drive sprocket 24 and the driven sprocket 26 to ensure transmission stability, a driven shaft 27 fixedly connected to the driven sprocket 26, another take-up reel 23 fixedly connected to the driven shaft 27, and three transmission wheels 28 that are frictionally driven with each take-up reel 23 via a wire rope 34. A guide frame 19 has lower limit pins 29 fixedly connected to both ends along its length, and a moving frame 20 has upper limit pins 30 fixedly connected to both ends along its length. Both transmission wheels 28 are connected via... The lower limit pin 29 is rotatably connected to the guide frame 19. Another transmission wheel 28 is rotatably connected to the limit block 32 via the connecting pin 31. The limit block 32 is slidably installed in the limit groove 18, which guides and limits the limit block 32. The upper surface of the limit block 32 is fixedly connected to the lower surface of the guide frame 19 near the motor 21 via the first spring 33, so that the limit block 32 is elastically connected to the lower surface of the guide frame 19. The drive shaft 22 and the driven shaft 27 are rotatably connected to the fixed frame 17 via the support base, thereby improving the rotational stability of the drive shaft 22 and the driven shaft 27. One output end of the wire rope 34 passes around two of the transmission wheels 28 near the motor 21 and is fixedly connected to an upper limit pin 30 of the moving frame 20 away from the motor 21. The other output end of the wire rope 34 passes around another transmission wheel 28 away from the motor 21 and is fixedly connected to another upper limit pin 30 of the moving frame 20 near the motor 21.

[0026] Since photovoltaic power generation systems are generally installed in open areas, in summer, the battery storage equipment inside the enclosure 1 will heat up rapidly after being exposed to direct sunlight, which will significantly affect the operation of the heat dissipation equipment. The fixed sunshade 10 initially reduces the temperature impact of the ring on the enclosure 1. However, when the direct sunlight lasts for a long time and the angle of illumination changes, the temperature inside the enclosure 1 will continue to rise. When the temperature sensor 16 detects a temperature higher than the second temperature threshold, relying solely on the fan 15 for heat dissipation is inefficient, and the fan 15 itself generates heat, which is also not conducive to rapid cooling of the enclosure 1. At this time, the controller 3 will start the motor 21 and simultaneously turn on the cabinet air conditioner 2 to utilize... The cabinet air conditioner 2 further cools the interior of the enclosure 1, thereby improving the cooling effect. To further reduce the impact of the external environment on the internal temperature of the enclosure 1, the motor 21 starts, driving the drive shaft 22 to rotate. The drive shaft 22 drives one of the winding pulleys 23 to rotate, and simultaneously drives the drive sprocket 24 to rotate. Under the engagement of the chain 25, the driven sprocket 26 rotates, which in turn drives the driven shaft 27 fixedly connected to it to rotate. The driven shaft 27 drives the other winding pulley 23 to rotate, thus making the two winding pulleys 23 rotate synchronously, thereby pulling the wire rope 34. One output end of the wire rope 34 passes sequentially around two transmissions near the motor 21. The lower drive wheel 28 is fixedly connected to an upper limit pin 30 on the moving frame 20 away from the motor 21. This lower drive wheel 28 is rotatably connected to the limit block 32. Under the elastic force of the first spring 33, the limit block 32 can drive the lower drive wheel 28 to ensure the tension of the wire rope 34 at all times. The other output end of the wire rope 34 passes around another drive wheel 28 away from the motor 21 and is fixedly connected to another upper limit pin 30 on the moving frame 20 near the motor 21. Then, under the rotation of the take-up wheel 23, the upper limit pin 30 near the motor 21 moves away from the first spring 33 as the wire rope 34 contracts, while the other upper limit pin 30 moves away from the first spring 33 as the wire rope 34 is unwound. Under the action of the fan 15, the fan moves synchronously away from the motor 21, thereby driving the movable frame 20 to slide under the limit of the guide frame 19. Finally, the two movable sunshades 11 move in opposite directions, expanding the sunshade area and effectively preventing the sun from shining directly on the energy storage box. Combined with the heat dissipation equipment inside the energy storage box, it can effectively prevent the box from failing to cool down quickly due to sun exposure, further reducing the impact of the external environment on the energy storage box, bringing convenience to the operation of the heat dissipation equipment, and facilitating the rapid cooling of the box 1. In winter, the fan 15 can be used to draw in cold air from outside and directly cool the inside of the box 1 quickly, avoiding the trouble of starting the cabinet air conditioner 2, reducing energy consumption and resource waste.

[0027] The transmission assembly includes a drive block 35 fixedly mounted on the bottom of one of the movable frames 20 near the motor 21, a driven block 36 slidably connected to the bottom of the drive block 35, both the drive block 35 and the driven block 36 being trapezoidal, a transmission rod 37 fixedly connected to the driven block 36, a transmission block 38 fixedly connected to the transmission rod 37, two sliding pins 39 slidably connected to the transmission block 38, a connecting rod 40 fixedly connected to the sliding pins 39, a set of connecting rods 40, and several connecting blocks 41 rotatably connected to the connecting rods 40. The top of the drive block 35 is fixedly connected to the movable frame 20, and the bottom of the drive block 35 is slidably connected to the inclined surface on the top of the driven block 36 through an inclined surface. The bottom of the driven block 36 is fixedly connected to the top of the transmission rod 37, and the bottom end of the transmission rod 37 passes through the drive block 36. The support frame 7 is fixedly connected to one side of the transmission block 38. The support frame 7 guides and limits the transmission rod 37. The top of the transmission rod 37 is fixedly connected to the support frame 7 by a second spring 42. A set of guide holes 43 are opened on the other side of the transmission block 38. Each guide hole 43 is slidably connected to one of the sliding pins 39. One sliding pin 39 is fixedly connected to one of the connecting rods 40. Four fixed seats 44 are fixedly connected to both sides of the connecting frame 4 along the height direction of the box 1. One end of each connecting block 41 is rotatably connected to one of the connecting rods 40 by a locking pin 45. The other end of each connecting block 41 is fixedly connected to the connecting shaft 46. The wind baffle 8 is fixedly sleeved on the connecting shaft 46. The connecting shaft 46 is rotatably sleeved in the fixed seat 44. The fixed seat 44 provides positioning support for the connecting shaft 46.

[0028] When the temperature inside the enclosure 1 continues to rise, and the temperature sensor 16 detects that the temperature exceeds the second temperature threshold, the cabinet air conditioner 2 will be activated simultaneously with the fan 15 to further improve the cooling effect inside the enclosure 1. At the same time, to further increase the air intake and accelerate the airflow and speed inside the enclosure 1, when the moving frame 20 extends outward to a certain position, it will cause the driving block 35 and the driven block 36 to slide relative to each other through the pressure of the inclined plane. This forces the driven block 36 to drive the transmission rod 37 downward, compressing the second spring 42. The transmission rod 37... Under the limiting guidance of the support frame 7, the transmission block 38 is driven to slide downward in the limiting hole 48 opened on the fixed plate 47, thereby causing the guide hole 43 opened on the transmission block 38 to drive the sliding pin 39 to move. The sliding pin 39 then pushes the two connecting rods 40 to move closer to each other. Then, under the rotational connection of the locking pin 45, the connecting block 41 is pulled to rotate. The connecting block 41 then drives the connecting shaft 46 to rotate under the limiting of the fixed seat 44, thereby driving the baffles 8 to rotate in opposite directions, so that each set of baffles 8 is in a parallel state, thereby expanding the air inlet, increasing the air volume, and improving the rapid cooling efficiency.
