Technical Field

[0001] The present invention relates to the technical field of energy storage battery boxes, and in particular to an energy storage battery box capable of preventing battery cells from overheating. Background Art

[0002] An energy storage battery is a device used to store electrical energy, and a battery box is a device used to store and protect energy storage battery packs. It is usually made of metal or high-strength plastic and has a sturdy shell that can protect the internal batteries from external physical impact, moisture intrusion, dust pollution, etc.

[0003] After searching, a Chinese patent disclosed a battery box and a battery box assembly containing the same, and its application publication number is CN109390507B. The patent has the function of quickly and accurately positioning the battery box relative to the bracket, making the cooperation between the battery box and the bracket more reliable, which is conducive to the effect of automated loading and unloading.

[0004] Battery boxes can be used to encapsulate and protect energy storage batteries. The existing technology has the following problems: when the energy storage battery is in continuous operation, it may generate a lot of heat. When it is difficult to dissipate heat for a long time, it is easy to cause accelerated aging of locations such as wiring. At the same time, some existing equipment will use cooling components to cool the battery cell positions, but this not only may consume high energy, but it is also difficult to adjust the cooling effect according to actual conditions, and is relatively inconvenient to use. Summary of the Invention

[0005] In order to flexibly adjust the battery box to save energy or improve heat dissipation efficiency according to actual needs, the present application provides an energy storage battery box that can prevent battery cells from overheating.

[0006] This application provides an energy storage battery box that can prevent battery cells from overheating, using the following technical solutions:

[0007] An energy storage battery box capable of preventing battery cells from overheating comprises a bottom box, a box body bolted to the inside of the bottom box, and a top box fixedly connected to the top of the box body. An air inlet frame is fixedly connected to the right side of the box body, heat dissipation fins are installed at the bottom, and auxiliary components are provided on the inside. Horizontal and vertical bars are fixedly connected to the inside of the bottom box, side plates are fixedly connected to the tops of the horizontal bars, and heat conduction plates are fixedly connected to the tops of the vertical bars. The side of the heat conduction plates close to the battery cells contacts the battery cells, and the tops of the vertical bars contact the battery cells. An integrally formed side plate is provided on the side of the heat conduction plates away from the battery cells. A cooling fan is installed on the inside of the air inlet frame, and a circulation sheet is provided on the inside of the air inlet frame. A guide rail is fixedly connected to the bottom of the inside of the bottom box.

[0008] The auxiliary components include a fin plate and several extensions. The side of the fin plate close to the side plate is rotatably connected to the side plate, the side of the extension plate close to the side plate is in contact with the side plate, the inner side of the guide rail is slidably connected to a guide block, the top of the guide block is fixedly connected to a push frame, the inner side of the push frame is movably connected to a bracket, and the bracket is movably connected to the fin plate on the side close to the fin plate.

[0009] By adopting the above technical solution, the bottom box, the box body and the top box are matched, and the battery cells are installed on the inner side of the bottom box to protect them. The air inlet frame is matched with the cooling fan and the circulation sheet. When the cooling fan is started, the air flow in the external environment will be blown into the interior of the box body. The coolant medium inside the circulation sheet will reduce the temperature of the circulation sheet to achieve the effect of cooling the passing air flow, so that the air flow blown into the interior of the box body is stable and lower. When the temperature of the battery cell is moderate, the heat conduction plate directly in contact with the battery cell can conduct the heat of the battery cell and dissipate the heat through the air flow blown in by the cooling fan. The fins of the auxiliary components are controlled to open along the side panels. At this time, the extension parts are also opened to displace the flat sheets in accordance with the side panels and extend. At this time, the air flow needs to frequently pass through the fins, flat sheets and side panels along the side panels, thereby effectively extending the temperature. The time that the cold air flow stays can achieve a good heat dissipation effect without increasing the power of the cooling fan. At the same time, since the bottom of the battery cell is hollowed out, the heat dissipation effect of the bottom will be better. The heat dissipation fins set close to the side of the battery cell will also conduct heat. Since part of them penetrate the bottom box and extend to the outside, the temperature reduction efficiency is high, which further improves the cooling effect of the battery cell. When the temperature of the battery cell continues to rise under continuous operation and it is difficult to dissipate heat naturally, the fin plate of the auxiliary component is controlled to be reset and parallel to the side plate, and the flat plate is retracted to be parallel to the side plate. At this time, the airflow can pass smoothly through the outside of the battery cell and directly take away the heat. After increasing the power of the cooling fan, the dissipated heat can be taken away more efficiently, so that the battery cell can be cooled according to the actual heat generation situation to prevent its temperature from being too high.

[0010] Optionally, the extension piece includes a flat plate, the bottom of the flat plate is fixedly connected to an assembly rod, the outer side of the assembly rod is fixedly connected to a spring, the side of the spring away from the assembly rod is fixedly connected to a transmission plate, the bottom of the transmission plate is fixedly connected to a short plate, the bottom of the short plate is fixedly connected to a slider, and the outer side of the slider is slidably connected to the guide rail.

[0020] The energy storage battery box can prevent battery cells from overheating. The box body and the top box are arranged in coordination. The battery cells are installed inside the box body to protect them. The air intake frame cooperates with the cooling fan and the circulation plate. When the cooling fan is started, airflow from the external environment is blown into the interior of the box body. The coolant medium inside the circulation plate reduces the temperature of the circulation plate. When the temperature of the battery cells is moderate, the heat conducting plate directly in contact with the battery cells can conduct heat from the battery cells. The fins of the auxiliary component are controlled to be opened along the side plates. At this time, the extension piece is also opened. The airflow needs to frequently pass through the fins, flat plates and side plates along the side plates, thereby effectively extending the retention time of the cold airflow. It can achieve good heat dissipation effect while reducing the power of the cooling fan. When the temperature of the battery cells continues to rise under continuous operation and it is difficult to dissipate heat naturally, the fins of the auxiliary component are controlled to be reset and parallel to the side plates. The flat plates are retracted to be parallel to the side plates. At this time, the airflow can smoothly pass through the outside of the battery cells and directly remove heat. When the power of the cooling fan is increased, the dissipated heat can be removed more efficiently. The energy saving or heat dissipation efficiency can be flexibly adjusted according to actual needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following is combined with Figure 1-9 This application is described in further detail. Example

[0033] The embodiment of the present application discloses an energy storage battery box that can prevent battery cells from overheating, comprising a bottom box 1, a box body 2 bolted to the inner side of the bottom box 1, and a top box 3 fixedly connected to the top of the box body 2. An air inlet frame 4 is fixedly connected to the right side of the box body 2, a heat dissipation fin 5 is installed at the bottom of the bottom box 1, an auxiliary component 6 is provided on the inner side of the bottom box 1, a horizontal bar 7 and a vertical bar 8 are fixedly connected to the inner side of the bottom box 1, a side plate 9 is fixedly connected to the top of the horizontal bar 7, a heat conducting plate 10 is fixedly connected to the top of the vertical bar 8, a side of the heat conducting plate 10 close to the battery cell is in contact with the battery cell, and a top of the vertical bar 8 is in contact with the battery cell, and an integrally formed side plate 11 is provided on the side of the heat conducting plate 10 away from the battery cell, a cooling fan 12 is installed on the inner side of the air inlet frame 4, a circulation sheet 13 is provided on the inner side of the air inlet frame 4, and a guide rail 29 is fixedly connected to the bottom of the inner side of the bottom box 1;

[0034] The auxiliary assembly 6 includes a fin plate 601 and a plurality of extension members 602. The side of the fin plate 601 close to the side plate 9 is rotatably connected to the side plate 9. The side of the extension member 602 close to the side plate 11 is in contact with the side plate 11. The inner side of the guide rail 29 is slidably connected to a guide block 603. The top of the guide block 603 is fixedly connected to a push rack 604. The inner side of the push rack 604 is movably connected to a bracket 605. The side of the bracket 605 close to the fin plate 601 is movably connected to the fin plate 601.

[0035] By setting up a bottom box 1, a box body 2 and a top box 3, the battery cells are installed on the inner side of the bottom box 1 to protect them, and the air inlet frame 4 is set to cooperate with the cooling fan 12 and the circulation sheet 13. When the cooling fan 12 is started, the air flow in the external environment will be blown into the interior of the box body 2. The coolant medium inside the circulation sheet 13 will reduce the temperature of the circulation sheet 13 to achieve the effect of cooling the passing air flow, so that the air flow blown into the interior of the box body 2 is stable and lower. When the temperature of the battery cell is moderate, the heat conducting plate 10 that is in direct contact with the battery cell can conduct the heat of the battery cell and dissipate the heat through the air flow blown in by the cooling fan 12. The fin 601 of the auxiliary component 6 is controlled to be opened along the side plate 9. At this time, the extension piece 602 is also opened to displace the flat sheet 602a in contact with the side plate 11 and extend. At this time, the air flow needs to frequently pass through the fin 601, the flat sheet 602a and the side plate 11 along the side plate 9. Plate 11, thus effectively prolonging the retention time of the cold air flow, and a good heat dissipation effect can be achieved without increasing the power of the cooling fan 12. At the same time, since the bottom of the battery cell is hollowed out, the heat dissipation effect of the bottom will also be better, and the heat dissipation fins 5 arranged on the side close to the battery cell will also conduct heat. Since part of it passes through the bottom box 1 and extends to the outside, the temperature reduction efficiency is high, which further improves the cooling effect of the battery cell. When the temperature of the battery cell continues to rise under continuous operation and it is difficult to dissipate heat naturally, the fin plate 601 of the control auxiliary component 6 is reset and parallel to the side plate 9, and the flat plate 602a is retracted to be parallel to the side plate 11. At this time, the airflow can pass smoothly through the outside of the battery cell and directly take away the heat. After increasing the power of the cooling fan 12, the dissipated heat can be taken away more efficiently, so that the battery cell can be dissipated according to the actual heat generation situation to prevent its temperature from being too high.

[0036] Among them, the inner side of the guide rail 29 is rotatably connected to two screw rods 15, and the outer sides of the rear sides of the two screw rods 15 are fixedly connected to gears 16, and the two gears 16 are meshed and connected. The front side of the guide rail 29 is fixedly connected to a control motor 17, and the output end of the control motor 17 is fixedly connected to the right screw rod 15. By setting two screw rods 15 to transmit through the gears 16, the control motor 17 can simultaneously drive the two screw rods 15 to rotate, and make the rotation directions of the two screw rods 15 opposite, so as to drive the sliders 602f and guide blocks 603 on both sides of the battery cell to move toward or in the opposite direction. The side of the side plate 9 close to the battery cell is fixedly connected to a sub-bar 18, and the inner side of the sub-bar 18 is fixedly connected to a rotating shaft 19. The outer side of the rotating shaft 19 is rotatably connected to the fin plate 601. By setting the sub-bar 18 to cooperate with the rotating shaft 19, it is convenient to supply the fin plate 601 to rotate or deflect along the side plate 9, so as to control the opening or retraction of the fin plate 601.

[0037] The inner side of the side plate 9 is provided with a movable groove 20, and the bracket 605 is arranged on the inner side of the movable groove 20. The outer side of the secondary bar 18 is fixedly connected with a torsion spring 21. The torsion spring 21 is fixedly connected to the fin plate 601 on the side close to the fin plate 601. By setting the movable groove 20 and cooperating with the torsion spring 21, the movable groove 20 can provide a position space for the bracket 605 to push or pull the fin plate 601, and the torsion spring 21 is used to assist the fin plate 601 to reset after being force-bearing. The outer side of the fin plate 601 is fixedly connected to the limit frame 22, and the inner side of the limit frame 22 is slidably connected to the limit block 23. The outer side of the limit block 23 is rotatably connected to the bracket 605. By setting the limit frame 22 and cooperating with the limit block 23, when the bracket 605 pushes or pulls the fin plate 601, the bracket 605 and the limit block 23 will rotate relative to each other, and the limit block 23 slides on the inner side of the limit frame 22, which can reasonably transmit the fin plate 601 to avoid the structure from getting stuck and being difficult to use.

[0038] An air guide plate 24 is fixedly connected to the right side of the side plate 9, a plurality of slots are provided on the inner side of the heat conducting plate 10, an exhaust slot 25 is provided on the left side of the box body 2, and a partition plate 26 is fixedly connected to the left side of the inner side of the box body 2. By providing the air guide plate 24, it is easy to guide the passing airflow to avoid flowing to a position where it will not contact the battery cells, and effectively utilize the circulation space of the airflow;

[0039] The partition 26 is provided to prevent impurities in the external environment from entering the interior of the box body 2 through the exhaust slot 25 when the air flow is discharged through the exhaust slot 25. The outer side of the heat dissipation fin 5 is provided with an integrally formed protrusion, which is snap-fitted to the bottom box 1. The inner and outer sides of the bottom box 1 are bonded with sealing strips 27, which are provided on the outer side of the protrusion.

[0040] By setting the raised portion, the heat dissipation fins 5 can be firmly installed inside the bottom box 1. The sealing strip 27 can improve the sealing of the structure and avoid the deterioration of the sealing of the bottom box 1. The circulation sheet 13 is made of hollow aluminum. The two adjacent circulation sheets 13 are connected by a cooling pipe. The cooling pipe is externally connected to the cooling circulation system. The outer side of the air inlet frame 4 is fixedly connected with a blocking net 28. The circulation sheet 13 made of hollow aluminum can facilitate the circulation of cooling medium. The external cooling circulation system cooperates with the cooling pipe to facilitate continuous circulation and supply of coolant to the inside of the circulation sheet 13. The blocking net 28 can facilitate the blocking of larger external impurities.

[0041] The working principle of this embodiment is as follows: when in use, if the temperature of the battery cell is moderate, the air inlet frame 4 cooperates with the cooling fan 12 and the circulation sheet 13. When the cooling fan 12 is started, the airflow in the external environment will be blown into the interior of the box body 2. The coolant medium inside the circulation sheet 13 will reduce the temperature of the circulation sheet 13 to achieve the effect of cooling the passing airflow, so that the airflow blown into the interior of the box body 2 is stable and lower. The heat conducting plate 10 that is in direct contact with the battery cell can conduct the heat of the battery cell and dissipate the heat through the airflow blown in by the cooling fan 12. The fin 601 of the control auxiliary component 6 is opened along the side plate 9. At this time, the two screw rods 15 are driven by the control motor 17 through the gear 16. The rotation directions of the two screw rods 15 are opposite to drive the sliders 602f and the guide blocks 603 on both sides of the battery cell to move toward each other, so as to open the extension piece 602 and make the flat sheet 602a fit the side plate 11 and extend. At this time, the airflow needs to frequently pass through the fins 601, the flat sheets 602a and the side panels 11 along the side panels 9, thereby effectively extending the retention time of the cold airflow, and achieving a good heat dissipation effect without increasing the power of the cooling fan 12. At the same time, the bottom of the battery cell is not placed directly, so the ground can also be used as a heat dissipation surface. The heat dissipation fins 5 arranged on the side close to the battery cell will also conduct heat. Since part of the heat dissipation fins passes through the bottom box 1 and extends to the outside, the temperature reduction efficiency is high, which further improves the cooling effect of the battery cell. When the temperature of the battery cell continues to rise under continuous operation and it is difficult to dissipate heat naturally, the fins 601 of the control auxiliary component 6 are reset and parallel to the side panels 9, and the flat sheets 602a are retracted to be parallel to the side panels 11. At this time, the airflow can pass smoothly through the outside of the battery cell and directly take away the heat. Increasing the power of the cooling fan 12 can more efficiently take away the emitted heat. Example

[0042] refer to Figure 4, an energy storage battery box that can prevent battery cells from overheating also includes an extension piece 602, wherein the extension piece 602 includes a flat sheet 602a, the bottom of the flat sheet 602a is fixedly connected to a mounting rod 602b, the outer side of the mounting rod 602b is fixedly connected to a spring 602c, the side of the spring 602c away from the mounting rod 602b is fixedly connected to a transmission plate 602d, the bottom of the transmission plate 602d is fixedly connected to a short plate 602e, the bottom of the short plate 602e is fixedly connected to a slider 602f, the outer side of the slider 602f is slidably connected to the guide rail 29, and by setting the slider 602f to slide along the guide rail 29, the short plate 602e connected thereto can push the transmission plate 602d connected thereto toward or away from the heat conducting plate 10, and the spring 602c is fixed to the flat sheet 60 2a moves excessively until it contacts the heat conducting plate 10, a certain amount of additional displacement space can be provided to the transmission plate 602d to facilitate the transmission of the screw 15. Since the sizes of the multiple flat plates 602a decrease successively from the air inlet position to the air exhaust position, when the flat plates 602a are opened, the air flow passing space near the air outlet position is larger, and the air flow passing space near the air inlet position is smaller, and the cross-sectional area of the air flow channel will be reduced accordingly, which will relatively accelerate the air flow speed, because the air flow will first pass through the right side of the box body 2, and when entering the left side of the box body 2, the temperature will rise because some heat is taken away. The cross-sectional area of the air flow channel on the left side of the bracket 605 can relatively prolong the residence time of the air flow on the left side of the box body 2, thereby avoiding a large temperature difference between the left and right sides of the battery cell.

[0043] Among them, the inner side of the assembly rod 602b is slidably connected to the slide rod 14, and the spring 602c is arranged on the outer side of the middle slide rod 14. By setting the slide rod 14, it is used to limit the relative movement of the assembly rod 602b and the transmission plate 602d, and at the same time limit the deformation of the spring 602c, and prevent excessive wear or difficulty in resetting caused by its radial deformation.

[0044] Working principle of this embodiment: During use, by setting the slider 602f to slide along the guide rail 29, the short plate 602e connected thereto can push the transmission plate 602d connected thereto toward or away from the heat conducting plate 10. The spring 602c can provide a certain amount of additional displacement space for the transmission plate 602d when the flat plate 602a moves excessively until it contacts the heat conducting plate 10, so as to facilitate the transmission of the screw 15. Since the size of the multiple flat plates 602a decreases from the air inlet position to the air outlet position, when the flat plates 602a are opened, the air flow space near the air outlet position is larger, while the air flow space near the air inlet position is smaller. The cross-sectional area of the air flow channel is correspondingly reduced, which will relatively increase the air flow speed. Because the air flow first passes through the right side of the box 2 and takes away some heat when entering the left side of the box 2, the air flow temperature on the left side of the box 2 is higher than that on the right side. The cross-sectional area of the air flow channel on the left side of the bracket 605 is relatively extended to prolong the residence time of the air flow on the left side of the box 2. At the same time, the heat dissipation fan 12 is provided on the side of the battery cell to facilitate cooling of the battery cell connection plate position.

[0045] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
