[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Reference Figure 1-Figure 3A duct structure for an air-cooled energy storage cabinet includes a cluster frame. The top of the cluster frame is equipped with a duct A1, a duct B2, and a duct C3 via a duct support plate 4. The bottom of the cluster frame is provided with a duct bottom sealing plate A8, a duct bottom sealing plate B7, and a duct bottom sealing plate C6 corresponding to the duct A1, duct B2, and duct C3. The middle of the cluster frame is detachably provided with three sets of wind resistance plates 9 via bolts, corresponding to the positions of the duct A1, duct B2, and duct C3 respectively. The wind resistance plates 9 can be adjusted according to the fluid simulation and actual measurement conditions. Adjustment is performed. Each layer can hold 1*3 pieces. When the maximum number of pieces reaches 3n, the temperature uniformity of the cells in each pack can be adjusted. The air duct support plate 4 divides the cluster frame into two parts, the upper and lower parts. One end of the air duct A1, air duct B2, and air duct C3 is sealed against the air outlet of the air conditioner through a seal to prevent air leakage. The other end is directed to the bottom of the air duct support plate 4. The space below is the air duct. The air duct bottom sealing plate A8, the air duct bottom sealing plate B7, and the air duct bottom sealing plate C6 are respectively located in the three air ducts (i.e., air duct A, air duct B, and air duct C). Figure 3 The bottom layer (as shown) to prevent air leakage in the air duct;

[0019] An air duct side sealing plate A10 located at the side of the cluster frame is installed between the air duct A1 and the corresponding wind resistance plate 9.

[0020] When the device is in use, the wind resistance plate 9, the air duct bottom sealing plate C6, the air duct bottom sealing plate B7, the air duct bottom sealing plate A8, the air duct side sealing plate A10, and the inner wall of the cabinet force part of the fluid in the independent air duct (the air flowing out of the air conditioner outlet) to change its flow direction and flow into the air inlet holes on both sides of the Pack (the Pack is inserted into the device, such as Figure 3 As shown, the device is placed in the energy storage cabinet, the cabinet door is closed, and the air outlet of the air conditioner is offset against the air duct A1, air duct B2 and air duct C3. Figure 2 ), the fluid flows out through the spoiler fan plate in front of the Pack and merges into the return air outlet of the air conditioner to complete the circulation in the cabinet. Compared with the existing technology, in this device, the number of wind resistance plates 9 can be set according to different Packs and air conditioners, and it has strong applicability.

[0021] In this embodiment, the cluster frame includes a cluster frame bottom crossbeam 14, a cluster frame top crossbeam 15, and front and rear duct columns B11, front and rear duct columns A12, and front and rear duct columns C13 installed between the cluster frame bottom crossbeam 14 and the cluster frame top crossbeam 15. The air duct support plate 4 is installed on the cluster frame top crossbeam 15. The duct bottom sealing plate A8, the duct bottom sealing plate B7, and the duct bottom sealing plate C6 are installed on the cluster frame bottom crossbeam 14. The three wind resistance plates 9 are respectively installed on the duct front and rear columns B11, the duct front and rear columns A12, and the duct front and rear columns C13. The duct side sealing plate A10 is installed on the duct front and rear columns A12. The duct front and rear columns B11, the duct front and rear columns A12, and the duct front and rear columns C13 are fixed to the cluster frame bottom crossbeam 14 and the cluster frame top crossbeam 15 by welding to form the frame of the cluster frame and the duct.

[0022] In this embodiment, the front and rear columns B11, A12, and C13 of the duct are all mounted with left and right guide rails 5 of the Pack cluster rack. The left and right guide rails 5 of the Pack cluster rack are fixed to the front and rear columns B11, A12, and C13 of the duct by bolts (in this embodiment, M5*20 galvanized flat-head bolts are used). The number of layers n of the left and right guide rails 5 of the Pack cluster rack (n=7 in this embodiment) is equal to the number of layers n of the Pack cluster, which is determined by the energy storage system capacity E and the Pack capacity C. The calculation formula is as follows:

[0023] n = E / (2C);

[0024] Currently, Pack clusters are commonly arranged in two rows, but the Pack suitable for this product has air inlets on both sides and integrated air ducts inside.

[0025] In this embodiment, the wind resistance plate 9 is made of 8-mesh stainless steel metal mesh. According to different brands and models of air conditioners and specific parameters of the pack, wind resistance plates 9 with appropriate mesh sizes can be selected, and the installation position and number can be adjusted.
