DETAILED DESCRIPTION

[0042] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0043] The cluster frame air duct in the prior art includes side panels on all sides, and a plurality of air outlets are arranged on the side panels facing the cluster frame body. The air output is limited, and the heat dissipation effect is poor for battery modules with large heat dissipation requirements. To address this problem, the basic technical concept of the utility model is to cancel the side panels facing the cluster frame body, and to form an air trough together with the left and right connecting plates and the back plate. The side of the air trough facing the cluster frame body is a completely open air outlet, and the cold air entering the air trough can be blown out through the air outlet, so that the air output is maximized, thereby improving the heat dissipation effect.

[0044] Embodiment of the cluster frame in the utility model:

[0045] like Figure 1 , Figure 2 , Figure 4 As shown, the cluster frame includes a cluster frame body 1 and a cluster frame air duct arranged on the back side of the cluster frame body 1. The cluster frame body 1 is used to place the battery plug-in box. Its specific structure belongs to the prior art and will not be described in detail in the present utility model. Different from the prior art, the cluster frame air duct in the present utility model includes a left connecting plate 2, a right connecting plate 3 and a back plate 4 connected to the left and right connecting plates. The back plate 4 is located at one end of the left and right connecting plates away from the cluster frame body 1, and in this embodiment, the cluster frame bodies 1 are arranged in rows front and back, and the front and rear rows of cluster frame bodies 1 are arranged "back to back", and the above-mentioned cluster frame air ducts are provided on their back sides, and the two cluster frame air ducts share a back plate 4, and the back plate 4 is arranged vertically.

[0046] In this embodiment, the top of the left connecting plate 2, the right connecting plate 3 and the back plate 4 form an air inlet for communicating with the main air duct in the energy storage container, and the air inlets of the air ducts of the two rows of cluster frame bodies 1 are arranged closely together, which is convenient for docking with the air outlet structure on the main air duct. An air outlet is formed between the ends of the left and right connecting plates close to the cluster frame body 1, and the ends of the left and right connecting plates close to the cluster frame body 1 are respectively connected to the cluster frame body 1, so that the left and right connecting plates and the back plate 4 jointly form an air trough, and the side of the air trough facing the cluster frame body 1 is a completely open air outlet, so that the cold air entering the air trough can be blown out through the air outlet, and the air outlet reaches the maximum, thereby improving the heat dissipation effect.

[0047] Specifically, the left connecting plate 2 and the right connecting plate 3 are respectively provided with fixed folding edges at one end close to the cluster frame body 1. Taking the right connecting plate 3 as an example, Figure 5 As shown, a fixed fold 31 is provided on the right connecting plate 3. The fixed folds on the left and right connecting plates extend toward each other, and the fixed folds are fixedly connected to the cluster frame body 1 by screws. Figure 3As shown, a connecting plate slot 41 is provided on the side of the back panel 4 facing the left and right connecting plates, and the ends of the left and right connecting plates away from the cluster frame body 1 are respectively inserted into the corresponding connecting plate slots 41. Since the two cluster frame air ducts share a back panel 4, connecting plate slots 41 are respectively provided on the front and rear sides of the back panel 4 for the left and right connecting plates on both sides to be inserted respectively.

[0048] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the cluster frame air duct also includes at least one partition plate 5 located between the left and right connecting plates, one end of the partition plate 5 is connected to the cluster frame body 1, and the other end is connected to the back plate 4. There are two partition plates 5 in this embodiment, and the two partition plates 5 evenly divide the space between the left connecting plate 2 and the right connecting plate 3 into three diversion air ducts, each of which is used to blow air to a row of battery plug boxes on the cluster frame body 1, that is, each row of battery plug boxes has a separate diversion air duct, and the air intake of each diversion air duct is consistent, so that the back of the cluster frame body 1 is evenly inflowed, thereby making the heat dissipation of the battery modules in the cluster more uniform.

[0049] Furthermore, if Figure 5 As shown, one end of the partition 5 is provided with a connecting fold 51, and the connecting fold 51 is fixedly connected to the cluster frame body 1 by screws. Figure 3 As shown, a partition slot 42 is provided on the side of the back plate 4 facing the partition 5, and the other end of the partition 5 is inserted into the partition slot 42. Similarly, partition slots 42 are provided on the front and rear sides of the back plate 4 to allow the partitions 5 on both sides to be inserted. The left connecting plate 2, the right connecting plate 3 and the partition 5 are connected to the back plate 4 by plugging, which can facilitate the assembly of the cluster frame. At the same time, by providing a sealing strip on the groove wall of the slot, the sealing of the cluster frame air duct can also be ensured.

[0050] In addition, the back top ends of the front and rear rows of cluster frame bodies 1 are fixedly connected by a connecting plate 6 to enhance the connection strength between the two rows of cluster frame bodies 1. The "double cluster" form of cluster frame in the utility model can not only accommodate a larger number of battery plug-in boxes, but also ensure the structural strength of the entire cluster frame. The heat dissipation effect of the battery plug-in boxes in the cluster is more uniform. At the same time, compared with the prior art, the side panel facing the cluster frame body is omitted, the air outlet is increased, the heat dissipation effect is improved, and the cluster frame air ducts of the two rows of cluster frame bodies share a back panel, the overall quality is also reduced, the manufacturing and installation processes can be reduced, and costs can be saved.

[0051] Furthermore, if Figure 5As shown, in order to prevent the connection plate 6 from protruding from the top surface of the cluster frame body 1 and facilitate the docking of the cluster frame air duct with the main air duct, an avoidance notch 43 for avoiding the connection plate 6 is provided at the top of the back plate 4. In addition, the connection plate 6 is formed by bending a plate, and includes a bottom plate 61 and two side plates 62 connected to the bottom plate 61. The two side plates 62 are bent upward relative to the bottom plate 61, which can improve the overall structural strength of the connection plate 6. In addition, the side plates 62 are extended from the front and rear ends of the bottom plate 61, and the extended part is fixedly connected to the cluster frame body 1 by screws, so as to facilitate installation.

[0052] In other embodiments of the cluster frame: the connecting plate connecting the front and rear rows of cluster frame bodies can also be fixed on the side of the cluster frame body, and in this case, there is no need to set an avoidance gap on the back plate. Of course, in other embodiments, the connecting plate can be omitted, and the front and rear rows of cluster frame bodies are only connected to the back plate through the left connecting plate, the right connecting plate and the middle partition.

[0053] In other embodiments of the cluster rack: the cluster rack can also be in a "single cluster" form, that is, an independent single-row cluster rack. For each single-row cluster rack, its cluster rack air duct includes a back panel.

[0054] In other embodiments of the cluster frame: the connection between the partition and the back plate may not be plug-in, and the partition is fixedly connected to the back plate through a folded edge, and the fixing method may be bolt connection or welding.

Of course, in other embodiments, the connecting fold may not be set at the end of the partition close to the cluster frame body, and the end of the partition is directly fixed to the cluster frame body by bolts, and of course it can also be fixed by welding.

[0056] In other embodiments of the cluster rack: only one partition plate may be provided between the left and right connecting plates, or three partition plates may be provided, and the specific number is determined by the number of rows of battery plug boxes that can be placed in the cluster rack body. Of course, in other embodiments, no partition plate may be provided regardless of the number of rows of battery plug boxes, and in this case, each row of battery plug boxes shares one air duct.

[0057] In other embodiments of the cluster frame: the fixed folded edges on the left and right connecting plates can also be welded and fixed to the cluster frame body. Of course, in other embodiments, the fixed folded edges may not be set at the ends of the left and right connecting plates close to the cluster frame body, and the ends of the left and right connecting plates are directly fixed to the cluster frame body by bolts, and of course they can also be fixed by welding.
