[0045] The following will be combined with schematic diagrams to describe the air duct assembly and energy storage container of the utility model in more detail, wherein the preferred embodiment of the utility model is shown, and it should be understood that those skilled in the art can modify the utility model described herein, while still achieving the beneficial effects of the utility model. Therefore, the following description should be understood as being widely known to those skilled in the art, and not as a limitation to the utility model.

[0046] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0047] Embodiment 1

[0048] like Figures 1 to 3 As shown, an embodiment of the utility model proposes an air duct assembly, including a flow-averaging air duct 1 , an air outlet structure 2 and an air guide plate 3 .

[0049] The flow-balanced air duct 1 includes a main air duct 11 and two side air ducts 12 that are interconnected.

[0050] The two side air ducts 12 are symmetrically arranged on both sides of the main air duct 11, wherein the side air duct 12 is arranged as a wedge-shaped structure, and the tip of the side air duct 12 faces the side away from the main air duct 11. The wedge-shaped wall of the side air duct 12 guides the air volume entering the main air duct 11, so that the air volume can flow to the tip of the side air duct 12, thereby improving the air intake of the air outlet structure 2 located at the tip of the side air duct 12, and avoiding the situation that the air outlet structure 2 located at the tip of the side air duct 12 is too far from the air inlet, resulting in less air volume, which in turn causes uneven air volume between multiple energy storage devices and the inability to meet the temperature control requirements of local energy storage devices.

[0051] The air outlet structure 2 is arranged in the uniform flow air duct 1, and the two ends are respectively connected to the tips of the two side air ducts 12, so as to divide the uniform flow air duct 1 into two air flow channels, and conduct the flow again. That is, the entire air duct chamber is divided into two independent air flow channels, so that the main air duct 11 can be simultaneously inlet by two air inlets, and can carry out targeted regional temperature control, so as to improve the cooling (heating) effect of the energy storage device, and effectively improve the cooling (heating) efficiency of the energy storage device.

[0052] The air guide plate 3 is arranged in the air flow channel, with one end perpendicular to the air outlet structure 2 and the other end extending toward the air outlet direction of the main air duct 11 to separate the air flow channel. That is, the air guide plate 3 can divide the air flow channel into two chambers surrounded by the main air duct 11, the air guide plate 3, the air outlet structure 2 and the inner wall of the side air duct 12, so that when air volume is input into the air inlet of the main air duct 11, the air volume can quickly flow along the air guide plate 3 and the wedge-shaped wall of the side air duct 12 to the tip of the side air duct 12 (such as Figure 2 The air volume is concentrated in the middle part and only a part of the air volume flows to the outside, so that the air volume can evenly pass through the air outlet structure 2 to be transmitted to the energy storage device, thereby effectively improving the stability of the operation of the energy storage device.

[0053] It should be noted that in the prior art, most container energy storage devices are symmetrically arranged, so the air guide plate 3 is also limited here to be able to evenly divide the air volume at the air outlet of the main air duct 11 and improve the air volume distribution effect. Specifically, the extension trajectory of the air guide plate 3 coincides with the symmetrical center line of the main air duct 11.

[0054] Please continue reading Figure 1 and Figure 2 In this embodiment, the air outlet structure 2 is further limited to better divert the air volume entering from the main air duct 11.

[0055] Specifically, the air outlet structure 2 includes an air outlet module 21 , and the air outlet module 21 has a plurality of air outlet chambers 4 built therein.

[0056] One or more air flow holes 5 are provided on one side of the air outlet chamber 4 facing the air outlet of the main air duct 11 .

[0057] It should be particularly noted that the air outlet chamber 4 corresponds to the energy storage device. Due to the differences in the energy storage devices, the corresponding cooling (heating) requirements are also different. Therefore, the number of air flow holes 5 on the air outlet chamber 4 needs to correspond to the temperature control requirements of the energy storage device. For example, when the air volume required by one of the energy storage devices is small, the number of air flow holes 5 set on the outside of the matching air outlet chamber 4 also needs to be reduced accordingly.

[0058] In other embodiments, since in actual applications, some areas in the container do not require air volume (such as aisles and some electrical equipment with low temperature control requirements), in order to avoid wasting air volume resources, the air outlet structure 2 is further limited here.

[0059] Specifically, the air outlet modules 21 are provided in plurality, and the air outlet structure 2 further includes a connecting module 22, which is provided between two adjacent air outlet modules 21 to connect the two air outlet modules 21. It should be noted that the area corresponding to the lower portion of the connecting module 22 is an area with a lower temperature control requirement, thereby reducing the waste of air volume resources.

[0060] In this embodiment, a specific example is also given to better demonstrate the quantitative relationship between the connection modules 22 and the air outlet modules 21. For example, when the area inside the container that does not require air volume is set to two (N), correspondingly, the connection modules 22 are also set to two (N), and the corresponding air outlet modules 21 are set to three (N+1).

[0061] The connection module 22 may be configured as a connection piece formed by a connection plate surrounding a closed chamber, such as a connection piece formed by bending and surrounding a connection plate or a connection piece formed by connecting and surrounding a plurality of connection plates, which will not be described in detail here.

[0062] In addition, in order to facilitate the connection of the two air outlet modules 21, the connection module 22 is set to a rectangular structure. In other embodiments, the connection module 22 can also be set to other shapes according to needs, which will not be repeated here.

[0063] In a further embodiment, the air outlet module 21 is further limited so that no interference is formed when the two air outlets of the main air duct 11 transport the air volume.

[0064] Specifically, the air outlet module 21 includes two parallelly arranged flow equalizing plates 211 and a partition plate 212 .

[0065] The flow equalizing plate 211 is fixedly installed between the inner wall of the tip of the side air duct 12 and the outer wall of the connecting module 22 or between two adjacent connecting modules 22. For example, when there is one connecting module 22, the flow equalizing plate 211 is arranged between the inner wall of the tip of the side air duct 12 and the connecting module 22; and when there are more than one connecting module 22, the flow equalizing plates 211 at different positions may be arranged between two adjacent connecting modules 22.

[0066] The air flow holes 5 are arranged on the flow equalizing plate 211 .

[0067] The partition plate 212 is fixedly installed between the two flow equalizing plates 211 to form a plurality of the air outlet chambers 4 .

[0068] It should be particularly noted that the partition plate 212 includes a transverse partition plate and a plurality of longitudinal partition plates, and the transverse partition plate is disposed between the two flow equalizing plates 211 .

[0069] One end of the plurality of longitudinal partitions is connected to the transverse partition, and the other end is connected to the flow equalizing plate 211 .

[0070] Since the transverse partition is placed between the two equalizing plates 211, the chamber between the two equalizing plates 211 can be divided into two independent small chambers, and the small chamber can be further divided into a plurality of air outlet chambers 4 by means of the longitudinal partition. The two independent small chambers correspond to the two air outlets of the main air duct 11, respectively, so as to avoid convection and cross-flow when the air volume is input from the two air outlets, which may lead to poor cooling (heating) effect.

[0071] like Figure 1 and Figure 4 As shown, the bottom end of the air outlet structure 2 protrudes from the outside of the uniform flow air duct 1 so that the air volume can be output to the energy storage device in a more concentrated manner.

[0072] In a further embodiment, air-conditioning air inlets 6 are provided at both ends of the main air duct 11, and the two ends of the main air duct 11 are respectively connected to the air conditioners of the energy storage container.

[0073] Among them, the air-conditioning air inlet 6 is perpendicular to the air outlet structure 2, and the end of the air guide plate 3 is connected to the middle of the air-conditioning air inlet 6, so that the air guide plate 3 can divide the air-conditioning air inlet 6 into two symmetrical air inlets, so as to evenly distribute the air volume in the chamber formed by the main air duct 11, the air guide plate 3, the air outlet structure 2 and the inner wall of the side air duct 12, ensuring that the air volume can be output to the energy storage device more evenly.

[0074] Preferably, to facilitate the maintenance and installation of the air duct components, the main air duct 11 and the two side air ducts 12, as well as the air outlet structure 2 and the side air ducts 12 and the main air duct 11 can be set as a detachable structure, that is, assembled by components such as bolts. The modular setting of the main air duct 11, the side air duct 12 and the air outlet structure 2 can effectively simplify the installation process and improve the installation accuracy and efficiency.

[0075] Embodiment 2

[0076] like Figure 5 As shown, the difference between this embodiment and the first embodiment is that only one air outlet module 21 is provided, that is, there is no need to connect through the connecting module 22, which reduces the number of assemblies required for the equipment and improves the assembly speed.

[0077] Specifically, the air outlet module 21 includes two parallelly arranged flow equalizing plates 211 and a partition plate 212 .

[0078] One end of the flow balancing plate 211 is fixedly connected to the inner wall of the tip of the side air duct 12, and the other end is connected to the inner wall of the tip of the other side air duct 12. That is, the two ends of the flow balancing plate 211 are respectively connected to the two side air ducts 12, thereby saving the setting of the connection module 22, so that the connection module 22 does not need to be installed during the assembly process, which effectively improves the assembly speed.

[0079] The air flow holes 5 are arranged on the flow equalizing plate 211 , and the partition plate 212 is fixedly installed between two flow equalizing plates 211 to form a plurality of air outlet chambers 4 .

[0080] Embodiment 3

[0081] On the other hand, the utility model also proposes an energy storage container, comprising a plurality of energy storage devices arranged inside the container and the air duct assembly described in the above embodiment.

[0082] Wherein, the air outlet structure 2 is arranged directly above the plurality of energy storage devices.

[0083] Preferably, the air outlet structure 2 has a plurality of air outlet chambers 4, and the air outlet chambers 4 are provided with air flow holes 5 for gas to enter.

[0084] The number of the air outlet chambers 4 matches the number of the energy storage devices.

[0085] The number of the air flow holes 5 on the air outlet chamber 4 is adapted to the temperature control requirements of the energy storage device directly below the air outlet chamber 4, that is, a matching number of air flow holes 5 is opened on the corresponding air outlet chamber 4 according to the requirements of different energy storage devices.

[0086] The energy storage device includes a battery cluster and an electrical control device. It should be noted that, since the battery cluster will emit a large amount of heat when in use, the battery cluster should be placed below the air outlet chamber 4 with more (or denser) airflow holes 5 on the outer wall to ensure normal heat dissipation of the battery cluster; and the electrical control device requires a smaller air volume than the battery cluster, so the electrical control device can be placed below the air outlet chamber 4 with relatively fewer airflow holes 5 on the outer wall.

[0087] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
