Description

Technical Field

[0001] This invention relates to the technical field of energy storage batteries, and more specifically, to an energy storage battery rack and an energy storage battery container. Background Technology

[0002] In existing technologies, battery packs are tightly stacked inside energy storage battery containers, making heat dissipation difficult. Since the internal temperature of the batteries is typically high during operation, active cooling is necessary. Cooling methods for energy storage battery containers are divided into air cooling and liquid cooling. Liquid cooling poses a safety hazard due to leakage, while air cooling avoids this risk. However, air cooling typically uses air conditioning to cool the entire container, resulting in relatively poor cooling performance.

[0003] In summary, both the existing battery pack placement methods and air-cooling methods result in relatively low heat exchange efficiency for the battery pack. Summary of the Invention

[0004] The first objective of this invention is to provide an energy storage battery rack to solve the technical problem of low heat exchange efficiency inside energy storage battery containers in the prior art.

[0005] The energy storage battery rack provided by the present invention includes two rows of air duct type columns arranged opposite each other. The air duct type columns have a hollow structure and multiple air outlets are provided along the height direction of the air duct type columns. In the two rows of air duct type columns, multiple crossbeams are fixedly connected between the two opposite air duct type columns. The multiple crossbeams are spaced apart in the vertical direction. A support plate is connected between two crossbeams of the same height and arranged adjacently, and the distance between two adjacent support plates is greater than the height of the battery pack.

[0006] The energy storage battery rack provided by this invention can produce the following beneficial effects:

[0007] The energy storage battery rack provided by this invention adopts a duct-type column, which can not only play a major supporting role, but also serve as an air supply duct. This not only reduces the number of structures, but also reduces space occupation, and improves the functionality of the duct-type column. In use, the battery pack is placed on the pallet, allowing the air blown from the air conditioner to enter from the top of the duct-type column. The airflow is then obstructed by the side walls of the duct-type column and the bottom plate of the container, causing it to gather and change direction within the column before exiting through the outlet. This ensures that battery packs at different distances from the air conditioner, as well as those at the same distance but different heights, are quickly exposed to the air and exchange heat, significantly improving heat exchange efficiency. Furthermore, this configuration results in more even airflow to the battery packs throughout the container, leading to more uniform temperature distribution and enhanced safety. The distance between adjacent upper and lower pallets is greater than the height of the battery packs, facilitating easy loading and unloading and preventing stacking and compression. It also allows the upper surface of the battery packs to exchange heat with the air from the air conditioner, increasing the heat exchange area and further improving efficiency.

[0008] Furthermore, the cross-section of the duct-type column is rectangular, and the air outlet is located on the opposite side plates of the two duct-type columns.

[0009] Under this technical solution, the side panels of the columns forming the air duct are flat, which makes it easy to install crossbeams and open air outlets.

[0010] Furthermore, the support plate includes a plurality of ribs arranged side by side at intervals along the length of the crossbeam, and the width direction of the ribs is all arranged in the vertical direction; each end of the rib along its length is fixedly connected by a connecting plate.

[0011] In this technical solution, because the width of the rib is greater than its thickness, the supporting strength of a single rib is enhanced. Furthermore, since the width of the rib is arranged vertically, a greater number of ribs can be arranged along the length of the beam, further improving the overall supporting strength. Moreover, with the same supporting strength, this arrangement allows for a larger gap between adjacent ribs, facilitating ventilation at the bottom of the battery pack. Of course, in other embodiments of this application, the ribs can also be arranged horizontally.

[0012] Furthermore, the crossbeam includes a support plate, which is horizontally arranged, and the support plate is disposed on the support plate.

[0013] Furthermore, reinforcing plates are provided on both sides of the crossbeam extending downwards along the width direction, and the two ends of the reinforcing plates along the length direction are respectively fixedly connected to the two oppositely arranged air duct type columns.

[0014] Under this technical solution, the reinforcing plate strengthens the support plate, thereby increasing the support strength of the support plate; moreover, the increased connection area between the crossbeam and the air duct column improves the connection firmness and reliability, which is beneficial to improving the overall structural strength of the battery rack.

[0015] Furthermore, the support plate is provided with a plurality of ventilation openings along its length, and each ventilation opening is located between two adjacent ribs of the support plate.

[0016] Under this technical solution, the two ends of the bottom of the battery pack can exchange heat with the horizontal airflow in the gap between adjacent ribs, and can also exchange heat with the vertical airflow through the gap between the ribs and the vents on the support plate, resulting in better heat exchange effect.

[0017] Furthermore, the multiple ribs of the pallet are evenly arranged, and the ventilation openings in each column of the crossbeam are evenly arranged along the length of the crossbeam.

[0018] Under this technical solution, uniform arrangement helps to ensure the uniformity of heat exchange, thereby improving the overall temperature uniformity inside the container.

[0019] Furthermore, the distance between two adjacent ribs is consistent with the distance between two adjacent ventilation openings in each column of ventilation openings of the crossbeam.

[0020] Furthermore, the number of ventilation openings is at least two rows, and each row of ventilation openings is symmetrically arranged with respect to the long axis of the support plate; among the support plates at the same height, adjacent ends of two adjacent support plates share a crossbeam.

[0021] This technical solution reduces the number of air duct columns and beams, thus lowering costs, and the battery rack occupies less space, which helps improve the space utilization rate inside the container.

[0022] Furthermore, the length of the tray is greater than the length of the battery pack.

[0023] Under this technical solution, when battery packs are placed on the tray, there are gaps between adjacent battery packs in the same row, which is more conducive to the battery packs exchanging heat fully.

[0024] The second objective of this invention is to provide an energy storage battery container to solve the technical problem of low heat exchange efficiency inside the energy storage battery container in the prior art.

[0025] The energy storage battery container provided by the present invention includes a container body and an air conditioner, an air supply duct, and several energy storage battery racks disposed in the container body. The energy storage battery racks are the aforementioned energy storage battery racks. The air inlet end of the air supply duct is disposed at the air outlet of the air conditioner. The air supply duct is provided with multiple air outlet ends, and the air outlet ends are connected to the upper end of the air duct-type column of the energy storage battery rack.

[0026] The energy storage battery container provided by the present invention has all the beneficial effects of the aforementioned energy storage battery rack, which will not be repeated here. Attached Figure Description

[0036] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0037] This embodiment provides an energy storage battery rack 100, such as Figure 1 and Figure 2 As shown, the energy storage battery rack 100 includes two rows of air duct type columns 110 arranged opposite each other. The air duct type columns 110 have a hollow structure and multiple air outlets 111 are opened along the height direction of the air duct type columns 110. In the two rows of air duct type columns 110, multiple crossbeams 120 are fixedly connected between the two air duct type columns 110 arranged opposite each other. The multiple crossbeams 120 are arranged at intervals in the vertical direction. A support plate 130 is connected between two crossbeams 120 arranged at the same height and adjacent to each other, and the distance between two adjacent support plates 130 is greater than the height of the battery pack 200.

[0038] The energy storage battery rack 100 provided in this embodiment adopts a duct-type column 110, which serves both as the main support and as an air supply duct. This reduces the number of structures and the space occupied, improving the functionality of the column. In use, the battery pack 200 is placed on the tray 130, allowing the air blown from the air conditioner to enter the duct-type column 110 from its top. The airflow is then obstructed by the side walls and the bottom plate of the container at the bottom of the duct-type column 110, causing it to gather and change direction within the column before exiting through the air outlet 111. This ensures that battery packs 200 at different distances from the air conditioner, as well as those at the same distance but different heights, can quickly receive the air from the air conditioner and exchange heat with it, thereby achieving optimal performance. This design significantly improves heat exchange efficiency. Furthermore, with this configuration, the airflow to the battery packs 200 throughout the container is more even, resulting in a more uniform temperature inside the container and enhanced safety. The distance between the upper and lower adjacent pallets 130 is greater than the height of the battery packs 200. This not only facilitates the loading and unloading of the battery packs 200 and prevents them from being squeezed when stacked, but also allows the upper surface of the battery packs 200 to exchange heat with the air from the air conditioner, increasing the heat exchange area of ​​the battery packs 200 and further improving heat exchange efficiency.

[0039] Specifically, in this embodiment, as Figure 1 and Figure 2As shown, the cross-section of the duct-type column 110 is rectangular, and the air outlet 111 is disposed on the opposite side plates of the two duct-type columns 110 arranged opposite each other. In this arrangement, the side plates surrounding the duct-type column 110 are flat, which facilitates the installation of the crossbeam 120 and the opening of the air outlet 111. Of course, in other embodiments of this application, the shape of the cross-section of the duct-type column 110 is not limited to the above-mentioned rectangle, but can also be other shapes, such as: the cross-section of the duct-type column 110 is circular or triangular, etc., as long as it can support the battery pack 200 and provide the air outlet 111 so that battery packs 200 of different heights can be blown by the air from the air conditioner as soon as possible, this application does not impose specific restrictions on the shape of the cross-section of the duct-type column 110.

[0040] Specifically, in this embodiment, as Figure 4 and Figure 5 As shown, the support plate 130 includes a plurality of ribs 131 arranged side-by-side at intervals along the length of the crossbeam 120, and the width direction of the ribs 131 is all arranged vertically; each end of the rib 131 is fixedly connected by a connecting plate 132 along its length. In this arrangement, since the width of the rib 131 is greater than its thickness, the supporting strength of a single rib 131 is enhanced; moreover, since the width direction of the ribs 131 is vertical, a greater number of ribs 131 can be arranged along the length direction of the crossbeam 120, thereby further improving the overall supporting strength; furthermore, with the same supporting strength, this arrangement allows for a larger gap between adjacent ribs 131, facilitating ventilation at the bottom of the battery pack 200. Of course, in other embodiments of this application, the ribs 131 can also be arranged horizontally.

[0041] More specifically, in this embodiment, one end of all ribs 131 is welded to a connecting plate 132, and the other end is welded to another connecting plate 132.

[0042] Specifically, in this embodiment, as Figure 4 As shown, the crossbeam 120 includes a support plate 121, which is horizontally arranged, and a support plate 130 is disposed on the support plate 121. Further, in this embodiment, the support plate 130 is welded to the crossbeam 120. Of course, in other embodiments of this application, the support plate 130 can also be directly placed on the crossbeam 120.

[0043] Specifically, in this embodiment, as Figure 3 and Figure 4As shown, reinforcing plates 123 extend downwards on both sides of the crossbeam 120 along its width, and the two ends of the reinforcing plates 123 along their length are fixedly connected to two oppositely arranged air duct type columns 110. In this configuration, the reinforcing plates 123 strengthen the support plate 121, thereby increasing its support strength; moreover, the increased connection area between the crossbeam 120 and the air duct type columns 110 improves the connection's firmness and reliability, which is beneficial for enhancing the overall structural strength of the battery rack.

[0044] Specifically, in this embodiment, as Figure 5 As shown, the support plate 121 has multiple vents 122 along its length, and each vent 122 is located between two adjacent ribs 131 of the support plate 130. With this configuration, the two ends of the bottom of the battery pack 200 can exchange heat with the horizontal airflow in the gap between adjacent ribs 131, and also with the vertical airflow through the gap between the ribs 131 and the vents 122 on the support plate 121, resulting in better heat exchange.

[0045] Specifically, in this embodiment, the following continues... Figure 5 As shown, the multiple ribs 131 of the pallet 130 are evenly arranged, and the vents 122 of each row of the crossbeam 120 are evenly arranged along the length of the crossbeam 120. This uniform arrangement helps to ensure the uniformity of heat exchange, thereby improving the overall temperature uniformity inside the container.

[0046] Specifically, in this embodiment, the following continues... Figure 5 As shown, there are two rows of ventilation openings 122, which are symmetrically arranged with respect to the long axis of the support plate 121. Among the pallets 130 at the same height, adjacent ends of two adjacent pallets 130 share a crossbeam 120. This arrangement can reduce the number of air duct columns 110 and crossbeams 120, reduce costs, and the battery rack occupies little space, which is beneficial to improving the space utilization rate inside the container.

[0047] It should be noted that in other embodiments of this application, the number of ventilation openings 122 on the support plate 121 of the crossbeam 120 is not limited to two columns. For example, the number of ventilation openings 122 can also be set to three or four columns.

[0048] Specifically, in this embodiment, as Figure 1 As shown, the length of the tray 130 is greater than the length of the battery pack 200. With this arrangement, when all battery packs 200 are placed on the tray 130, there are gaps between adjacent battery packs 200 in the same row, which is more conducive to the battery packs 200 extensibly exchanging heat.

[0049] This embodiment also provides an energy storage battery container, including a container body and an air conditioner, an air supply duct, and several energy storage battery racks 100 disposed within the container body. The energy storage battery racks 100 are as described above. The air inlet of the air supply duct is disposed at the air outlet of the air conditioner, and the air supply duct has multiple air outlets, which are connected to the upper end of the air duct-type column 110 of the energy storage battery rack 100. The energy storage battery container provided in this embodiment has all the beneficial effects of the aforementioned energy storage battery rack 100, which will not be repeated here.

[0050] Specifically, in this embodiment, an exhaust fan can be installed at the far end of the box relative to the air conditioner to promote the flow of gas inside the box, accelerate the heat exchange efficiency, and exhaust the high-temperature gas to the outside of the box.

[0051] Specifically, in this embodiment, the battery pack 200 placed on the energy storage battery rack 100 can have openings at the bottom to maximize the heat exchange between the internal battery and the gas inside the box.

[0052] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used merely 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 process, method, article, or apparatus.

[0053] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to the embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
