Description

Technical Field

[0001] This application relates to the field of battery installation technology, specifically to AC / DC string integrated energy storage containers. Background Technology

[0002] A Power Conversion System (PCS) is a device used to achieve bidirectional conversion of electrical energy. It is mainly used in AC-coupled energy storage systems such as grid-connected energy storage and microgrid energy storage. It connects the battery bank and the power grid (or load), and can realize the conversion of electrical energy from DC to AC and feed the AC power back into the power grid.

[0003] Currently, AC PCS and batteries need to be placed in two separate containers, which is not compact enough, takes up a lot of space, and the heat dissipation of the batteries inside the containers will affect the lifespan of the batteries and PCS. Relying solely on traditional cooling fans for heat dissipation is not effective. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides an AC / DC string integrated energy storage container. It features a rational container layout, placing the PCS and batteries within a single container, avoiding the need for separate containers for batteries and PCS, which occupies significant space. It also optimizes battery heat dissipation, preventing heat buildup inside the container and thus reducing the lifespan of the batteries and PCS. This solves the problems of requiring separate containers for AC PCS and batteries, resulting in a less compact structure and larger space requirements, and the ineffectiveness of traditional cooling fans in improving battery and PCS lifespan.

[0005] To achieve the above objectives, this application provides the following technical solution: an AC / DC string integrated energy storage container, comprising a container body, wherein equidistantly arranged square tubes are fixedly connected inside the container body, and equidistantly arranged mounting plates are provided on both sides of the square tubes. The outer surfaces of the mounting plates are fixedly connected to the outer surfaces of the square tubes, and batteries are provided between adjacent mounting plates. A PCS (Polymer Processing System) is provided inside the container body, and a first partition is provided at the edge of the PCS. A water chiller is provided inside the container body, and a second partition is provided at the edge of the water chiller. A first inlet is fixedly connected inside the water chiller. The water inlet pipe has two equidistantly arranged second inlet pipes fixedly connected to its outer circumference. Each second inlet pipe has a third inlet pipe fixedly connected to its outer circumference. Each third inlet pipe has an inlet connector fixedly connected to its end away from the second inlet pipe. The water chiller has a first outlet pipe fixedly connected to its interior. Each second outlet pipe has two equidistantly arranged second outlet pipes fixedly connected to its outer circumference. Each second outlet pipe has a third outlet pipe fixedly connected to its outer circumference. Each third outlet pipe has an outlet connector fixedly connected to its end away from the second outlet pipe.

[0006] The above solution requires placing the PCS and battery in two separate containers, resulting in a less compact structure and larger space occupation. The heat dissipation of the battery within the container affects the lifespan of both the battery and the PCS. Relying solely on traditional cooling fans is ineffective. By using a first partition to isolate the battery and PCS, and a second partition to isolate the battery and water chiller, the container is divided into battery, PCS, and water chiller areas. This rational layout places the PCS and battery within a single container, avoiding the need for separate containers and reducing space occupation. Furthermore, by incorporating a water chiller, first inlet pipe, second inlet pipe, third inlet pipe, inlet connector, first outlet pipe, second outlet pipe, third outlet pipe, and outlet connector, external water cooling pipes can be connected between the inlet and outlet connectors and run between the batteries, creating a cold water circulation system. This ensures timely heat dissipation for the batteries, optimizes heat dissipation, prevents heat buildup inside the container, and extends the lifespan of both the battery and PCS.

[0007] Furthermore, each of the mounting plates is an L-shaped structure, with the upper surface of the horizontal plate of the mounting plate in contact with the bottom surface of the battery.

[0008] With the above solution, the vertical part of the L-shaped mounting plate can be fixedly connected to the square tube, while also providing a surface for placing the battery, which facilitates battery installation.

[0009] Furthermore, the first partition and the second partition are fixedly connected to the box body through the bracket inside the box body, and the interior of the first partition and the second partition are both provided with rock wool.

[0010] The above solution divides the container into a battery area, a PCS area, and a water chiller area using the first and second partitions, resulting in a compact internal layout. This avoids placing the battery and PCS in two separate containers, thus saving space. Rock wool is a high-quality heat and sound insulation material, and its addition can significantly improve the insulation performance of the container and reduce the impact of the heat generated by the battery during operation on other components inside the container.

[0011] Furthermore, a protective door is hinged to one end of the housing, the protective door is located on the front of the water chiller, and a protective mesh is provided inside the protective door.

[0012] The above solution provides protection for the water chiller. The protective net not only effectively prevents external objects from entering the cabinet and affecting the normal operation of the water chiller, but also meets the heat dissipation requirements of the water chiller.

[0013] Furthermore, the protective door is provided with a latch on the front, and the protective door is fixedly connected to the box body by the latch.

[0014] The above solution uses a latch to securely connect the protective door and the housing, facilitating the opening and closing of the protective door and thus the maintenance of the water chiller.

[0015] Furthermore, the interior of the housing is provided with a first louver, which is located on one side of the PCS.

[0016] Through the above solution, the first louver can meet the ventilation and heat dissipation requirements of the PCS, ensuring that it will not overheat during long-term operation.

[0017] Furthermore, the interior of the housing is provided with a second louver, which is located on the front of the PCS.

[0018] Through the above solution, the second louver can work in conjunction with the first louver to optimize the heat dissipation effect of the PCS.

[0019] Furthermore, both the square tube and the mounting plate are made of aluminum alloy, and the outer surfaces of both the square tube and the mounting plate are coated with a corrosion-resistant coating.

[0020] Through the above-mentioned solutions, aluminum alloys have advantages such as light weight, high strength, and good corrosion resistance, making them very suitable for use in the skeleton and support structure of energy storage containers. Applying a corrosion-resistant coating can further improve the corrosion resistance of aluminum alloy materials and extend their service life.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This AC / DC string integrated energy storage container uses a first partition to isolate the battery and PCS, and a second partition to isolate the battery and water chiller. This divides the interior of the container into battery, PCS, and water chiller areas, allowing for a rational layout that places the PCS and batteries within a single container. This avoids the need for separate containers, reducing space usage. The container is equipped with a water chiller, first inlet pipe, second inlet pipe, third inlet pipe, inlet connector, first outlet pipe, second outlet pipe, third outlet pipe, and outlet connector. External water cooling pipes connect to the inlet and outlet connectors and run between the batteries, creating a cold water circulation system. This provides timely cooling for the batteries, optimizes heat dissipation, prevents heat buildup inside the container, and extends the lifespan of the batteries and PCS. This solution addresses the problems of using two containers for batteries and PCS, which results in a less compact structure, larger space requirements, and inadequate cooling performance of batteries within the container, which can affect their lifespan. Relying solely on traditional cooling fans also proves insufficient. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Please see Figure 1 , Figure 2 and Figure 3 The AC / DC string integrated energy storage container in this embodiment includes a container body 1. Equally spaced square tubes 2 are fixedly connected inside the container body 1. Equally spaced mounting plates 3 are provided on both sides of the square tubes 2. The outer surfaces of the mounting plates 3 are fixedly connected to the outer surfaces of the square tubes 2. Batteries 4 are provided between adjacent mounting plates 3.

A second partition 20 is provided at the edge of the water chiller 7. A first water inlet pipe 8 is fixedly connected inside the water chiller 7. The outer circle of the first water inlet pipe 8... The water chiller 7 is fixedly connected to a second water inlet pipe 9 arranged at equal intervals on its circumference. A third water inlet pipe 10 is fixedly connected to the outer circumference of each second water inlet pipe 9. A water inlet connector 11 is fixedly connected to the end of each third water inlet pipe 10 away from the second water inlet pipe 9. A first water outlet pipe 12 is fixedly connected to the inside of the water chiller 7. A second water outlet pipe 13 arranged at equal intervals is fixedly connected to the outer circumference of the first water outlet pipe 12. A third water outlet pipe 14 is fixedly connected to the outer circumference of each second water outlet pipe 13. A water outlet connector 15 is fixedly connected to the end of each third water outlet pipe 14 away from the second water outlet pipe 13.

[0031] Please see Figure 2 and Figure 4 Each mounting plate 3 is an L-shaped structure. The upper surface of the horizontal plate of the mounting plate 3 contacts the bottom surface of the battery 4. The vertical part of the L-shaped mounting plate 3 can be fixedly connected to the square tube 2, and at the same time, it provides a placement surface for the battery 4, which facilitates the installation of the battery 4.

[0032] Please see Figure 1 and Figure 2 The first partition 6 and the second partition 20 are fixedly connected to the container 1 through the internal support of the container 1. The first partition 6 and the second partition 20 are both filled with rock wool. The first partition 6 and the second partition 20 divide the container 1 into a battery area, a PCS area and a water chiller area, which makes the internal layout of the container 1 compact and avoids placing the battery 4 and PCS 5 in two containers, thus avoiding taking up too much space. Rock wool is a high-quality heat insulation and sound insulation material. Its addition can significantly improve the heat insulation performance of the container 1 and reduce the impact of the heat generated by the battery 4 during operation on other components inside the container 1.

[0033] Please see Figure 1 and Figure 2 A protective door 16 is hinged to one end of the housing 1. The protective door 16 is located on the front of the water chiller 7. The protective door 16 is equipped with a protective net inside. The protective door 16 can protect the water chiller 7. The protective net can not only effectively prevent external objects from entering the housing 1 and affecting the normal operation of the water chiller 7, but also meet the heat dissipation requirements of the water chiller 7.

[0034] Please see Figure 1 and Figure 2 The protective door 16 has a latch 17 on the front. The protective door 16 is fixedly connected to the housing 1 through the latch 17. The latch 17 fixes the protective door 16 and the housing 1, which facilitates the opening and closing of the protective door 16 and thus facilitates the maintenance of the water chiller 7.

[0035] Please see Figure 1 and Figure 2 The housing 1 has a first louver 18 inside, which is located on one side of the PCS5. The first louver 18 can meet the ventilation and heat dissipation requirements of the PCS5 and ensure that it will not overheat during long-term operation.

[0036] Please see Figure 1 The interior of the housing 1 is equipped with a second louver 19, which is located on the front of the PCS5. The second louver 19 can work in conjunction with the first louver 18 to optimize the heat dissipation of the PCS5.

[0037] Please see Figure 2 and Figure 4 Both the square tube 2 and the mounting plate 3 are made of aluminum alloy. The outer surfaces of both the square tube 2 and the mounting plate 3 are coated with a corrosion-resistant coating. Aluminum alloy has the advantages of being lightweight, high-strength, and corrosion-resistant, making it very suitable for use as the skeleton and support structure of energy storage containers. Coating with a corrosion-resistant coating can further improve the corrosion resistance of aluminum alloy materials and extend their service life.

[0038] In this embodiment, the AC / DC string integrated energy storage container uses a first partition 6 to isolate the battery 4 and PCS5, and a second partition 20 to isolate the battery 4 and the water chiller 7. This divides the interior of the container 1 into a battery area, a PCS area, and a water chiller area, allowing for a rational layout of the container. This avoids the need for two separate containers for the battery 4 and PCS5, reducing space usage. The water chiller 7, first inlet pipe 8, second inlet pipe 9, third inlet pipe 10, inlet connector 11, first outlet pipe 12, second outlet pipe 13, third outlet pipe 14, and outlet connector 15 allow external water cooling pipes to connect between the inlet connector 11 and the outlet connector 15 and pass between the batteries 4, forming a cold water circulation system. This provides timely heat dissipation for the batteries 4, optimizing their cooling effect, preventing heat buildup inside the container, and extending the lifespan of the batteries 4 and PCS5. This solves the problem of using two separate containers for the batteries 4 and PCS5. The placement structure of 5 is not compact enough and occupies a large space. The heat dissipation effect of battery 4 inside the container will affect the lifespan of battery 4 and PCS 5. Relying solely on traditional cooling fans will not provide adequate heat dissipation.

[0039] It should be noted that there is a cooling fan on the back of the box 1, which can further optimize the heat dissipation effect of the box 1. The first water inlet pipe 8 and the first water outlet pipe 12 are fixedly connected to the inside of the box 1 by fasteners. The outer circumferential surfaces of the second water inlet pipe 9 and the second water outlet pipe 13 are fixedly connected to the outer surface of the square tube 2, which improves the overall stability of the water inlet pipe and the water outlet pipe.

[0040] The working principle of the above embodiments is as follows:

[0041] The first partition 6 and the second partition 20 divide the container 1 into a battery area, a PCS area, and a water chiller area, making the internal layout of the container 1 compact and avoiding the need to place the batteries 4 and PCS 5 in two separate containers, thus avoiding the occupation of too much space. External water cooling pipes can be used to connect the inlet connectors 11 and outlet connectors 15 on adjacent third water inlet pipes 10 and third water outlet pipes 14, and the external water cooling pipes are run between the batteries 4. During the cooling operation, the water chiller 7 is started and cold water is delivered through the first water inlet pipe 8. The cold water passes through the first water inlet pipe 8, the second water inlet pipe 9, the third water inlet pipe 10, the inlet connector 11, the external water cooling pipe, the outlet connector 15, the third water outlet pipe 14, the second water outlet pipe 13, and the first water outlet pipe 12 in sequence, and finally flows back into the water chiller 7 to form a cold water circulation. During the circulation of cold water, the heat generated by the batteries 4 will be carried away and the heat dissipation effect of the container will be optimized.

[0042] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
