Description

Technical Field

[0001] This utility model relates to the field of energy storage equipment, and in particular to a containerized energy storage device. Background Technology

[0002] With the comprehensive development of new energy technologies, the technology of using containers as an energy storage method has also been widely applied.

[0003] Currently, in the design of large-capacity photovoltaic / energy storage integrated units, the heat dissipation of photovoltaic / energy storage equipment is generally designed with air intake at the top and exhaust at the bottom on the front or side. When integrated with the transformer in a 20-foot or 40-foot container, the distance between the photovoltaic / energy storage equipment and the transformer is very small due to the size limitations of the container. At the same time, the transformer will generate a lot of heat when it is working and exhaust it upwards. At this time, the hot air will be drawn into the photovoltaic / energy storage equipment through the air intake at the top, causing the photovoltaic / energy storage equipment to overheat, which is not conducive to the normal operation of the photovoltaic / energy storage equipment. In the existing solutions, a baffle is usually installed on the top of the photovoltaic / energy storage equipment to prevent the hot air generated by the transformer from entering the area where the photovoltaic / energy storage equipment is located.

[0004] However, this method will affect the heat dissipation of photovoltaic / energy storage equipment, which is also detrimental to the normal operation of photovoltaic / energy storage equipment.

[0005] In view of this, it is necessary to improve existing containerized energy storage devices to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a containerized energy storage device to solve the problem of poor heat dissipation in existing containerized energy storage devices.

[0007] To achieve the above objectives, this utility model provides a containerized energy storage device, which includes: A container rack, within which an energy storage area and a transformer area are formed; A transformer, wherein the transformer is located within the transformer area; An energy storage device, wherein the energy storage device is installed within the energy storage area; A partition wall, which is installed inside the container frame, is used to separate the energy storage area and the transformer area; A top cover, which is located on top of the energy storage area and adjacent to the transformer area; The container rack in the energy storage area is hollowed out except for the top cover to expose the energy storage equipment.

[0008] As a further improvement of this utility model, the number of energy storage areas is two, and the two energy storage areas are arranged on both sides of the transformer area, and the number of partition walls is two.

[0009] As a further improvement of this utility model, a turbulence fan is provided at the top of the partition wall, and the turbulence fan blows air toward the transformer area.

[0010] As a further improvement of this utility model, each partition wall is provided with two turbulence fans, and the two turbulence fans on each partition wall are spaced apart.

[0011] As a further improvement of this utility model, a sealing plate is provided on the side of the transformer area, the sealing plate is located close to the energy storage area, and the top of the sealing plate is configured as a structure with an upper seal and a lower opening.

[0012] As a further improvement of this utility model, sealing plates are provided on both sides of the transformer area, and two sealing plates are provided on each side.

[0013] As a further improvement of this utility model, the side of the transformer zone also includes a ventilation mesh plate located between the two sealing plates.

[0014] As a further improvement of this utility model, the containerized energy storage device also includes a low-voltage combiner cabinet, which is disposed inside the container frame and adjacent to the energy storage device.

[0015] As a further improvement of this utility model, the container rack is hollowed out at the top of the transformer area to expose the transformer.

[0016] The beneficial effects of this utility model are as follows: The containerized energy storage device of this utility model only sets a top cover on the top of the energy storage area near the transformer area, which has a small coverage area, thus reducing material and processing costs. At the same time, it can prevent hot air from the transformer area from being sucked into the energy storage device. By setting a turbulence fan, the upward convection of hot air is accelerated, avoiding the formation of a hot air stagnation area around the transformer, thereby improving heat dissipation efficiency and air convection.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] like Figures 1 to 3 As shown, the containerized energy storage device 100 of this utility model includes a container frame 1, a transformer 2, an energy storage device 3, a partition wall 4, and a top cover 5.

[0022] An energy storage area 11 and a transformer area 12 are formed inside the container frame 1, and the energy storage area 11 and the transformer area 12 are arranged adjacent to each other along the length of the container frame 1.

[0023] Transformer 2 is located in transformer area 12, and energy storage device 3 is located in energy storage area 11.

[0024] The partition wall 4 is installed inside the container frame 1 to separate the energy storage area 11 and the transformer area 12. The partition wall 4 can be made of metal or non-metal. In this embodiment, it is made of metal. The partition wall 4 can separate the transformer area 12 and the energy storage area 11, mainly to achieve the effect of isolating heat transfer.

[0025] The top cover 5 is located on top of the energy storage area 11 and is adjacent to the transformer area 12. The container frame 1 is perforated in the energy storage area 11 except for the top cover 5 to expose the energy storage device 3. The top cover 5 occupies about one-quarter to one-third of the area of ​​the top of the energy storage area 11. The top cover 5 is located adjacent to the transformer area 12 and can block hot air from the transformer area 12 from entering the energy storage area 11. The perforation at the top of the energy storage area 11 at the top of the top cover 5 allows the hot air in the energy storage area 11 to be discharged upward normally.

[0026] To ensure effective heat insulation, the top cover 5 has no holes or openings. The top cover 5 can be integrally fixed to the container frame 1 by welding, screw connection, or other methods, or it can be detachably fixed.

[0027] The containerized energy storage device 100 of this utility model can prevent hot air from the transformer zone 12 from entering the energy storage zone 11, and can also ensure that the energy storage zone 11 can dissipate heat normally. Therefore, the containerized energy storage device 100 has a better heat dissipation effect.

[0028] In this embodiment, there are two energy storage zones 11, which are located on both sides of the transformer zone 12, and there are two partition walls 4. In other embodiments, there may be only one energy storage zone 11, and the corresponding number of partition walls 4 may also be only one.

[0029] To better direct hot air into the energy storage area 11, in this embodiment, a baffle fan 6 is provided at the top of the partition wall 4, blowing air towards the transformer area 12. When the hot air in the transformer area 12 rises, the baffle fan 6 operates, which can accelerate the upward convection of the hot air and prevent the formation of a hot air stagnation zone around the transformer 2, thereby improving heat dissipation efficiency and air convection.

[0030] In this embodiment, each partition wall 4 is equipped with two deflector fans 6, which are spaced apart along the width of the container frame 1. That is, in this embodiment, there are a total of four deflector fans 6.

[0031] In other embodiments, the turbulence fan 6 may also be arranged in a long strip shape, covering the width of the entire container frame 1.

[0032] A sealing plate 7 is provided on the side of the transformer area 12. The sealing plate 7 is located close to the energy storage area 11, and the top of the sealing plate 7 is designed with an upper seal and a lower opening. The sealing plate 7 is designed in this way to allow air to enter from the bottom while preventing the hot air emitted by the transformer 2 during operation from being sucked into the energy storage device 3 in the adjacent energy storage area 11, thus preventing the energy storage device 3 from overheating.

[0033] In this embodiment, sealing plates 7 are provided on both sides of the transformer area 12, and two sealing plates 7 are provided on each side. Each sealing plate 7 is provided adjacent to the energy storage area 11.

[0034] The transformer zone 12 also includes a ventilation mesh plate 8 located between the two sealing plates 7 on its side. The ventilation mesh plate 8 enables air convection on both sides of the transformer zone 12, achieving better heat dissipation.

[0035] The containerized energy storage device 100 also includes a low-voltage combiner cabinet 9, which is installed inside the container frame 1 and adjacent to the energy storage device 3.

[0036] The container frame 1 has a perforated top section in the transformer section 12 to expose the transformer 2. Full exposure of the top of the transformer 2 improves heat dissipation.

[0037] The containerized energy storage device 100 of this utility model has a top cover 5 only installed on the top of the energy storage area 11 near the transformer area 12. The coverage area is small, which can reduce material and processing costs. At the same time, it can prevent the hot air of the transformer area 12 from being sucked into the energy storage device. By setting a turbulence fan 6, the upward convection of hot air is accelerated, avoiding the formation of a hot air stagnation area around the transformer 2, thereby improving heat dissipation efficiency and air convection.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
