DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] See also Figures 1 to 12, the utility model provides an energy storage battery cabinet.

[0035] The energy storage battery cabinet includes a cabinet body 100, a plurality of battery boxes 200 and an air conditioner 400. A battery cavity 101 is arranged in the cabinet body 100; the plurality of battery boxes 200 are arranged in the battery cavity 101, and a heat dissipation duct 201 is arranged in each battery box 200. A first air duct 110 is formed between the front side of the plurality of battery boxes 200 and the battery cavity 101, a second air duct 120 is formed between the rear side and the battery cavity 101, and a third air duct 130 is formed between the upper side and the battery cavity 101; the air conditioner 400 is provided with a hot air inlet 410 and a cold air outlet 420; the cold air outlet 420, the third air duct 130, the first air duct 110, the heat dissipation duct 201, the second air duct 120, and the hot air inlet 410 are connected in sequence to form an internal circulation duct.

[0036] Specifically, the third air duct 130 is formed at the gap above the stack of multiple battery boxes, and can be used for cold air to pass through. The flow path of cold air in this solution is: the high-power air conditioner 400 blows out cold air through the third air duct 130 into the first air duct 110, the cold air enters the heat dissipation air duct 201 inside the battery box 200 from the first air duct 110 and flows back to the second air duct 120 to become hot air, and finally flows back from the second air duct 120 to the hot air inlet 410 of the air conditioner 400. After the hot air is cooled into cold air inside the air conditioner 400, it flows out again from the cold air outlet 420 to form an internal circulation air duct to continuously cool the battery box 200. At the same time, in order to enhance the heat dissipation effect of the battery box 200, gaps can be formed between multiple battery boxes 200, and gaps are also formed between the multiple battery boxes 200 and the inner wall of the cabinet 100, so that the first air duct 110 and the second air duct 120 are directly connected to increase the contact area between the cold air and the battery box 200, thereby enhancing the heat dissipation effect.

[0037] The technical solution of the utility model realizes internal circulation of cold air to continuously dissipate heat from the battery box 200 through the design of an internal circulation air duct and the arrangement of an air conditioner 400. The cold air covers all the battery boxes 200 from top to bottom in the first air duct 110 and enters the heat dissipation air duct 201 inside the battery box 200. The cold air is in more complete contact with each battery box 200, and the cold air diffuses quickly inside the cabinet 100, resulting in better heat dissipation effect. At the same time, it can reduce external environmental temperature interference, prevent dust from entering, simplify the structure, and reduce production costs.

[0038] See also Figures 7 to 9Furthermore, the battery box 200 includes a fixing frame 210 and a plurality of single cells 220. The fixing frame 210 is provided with a plurality of mounting slots 230 arranged in an array, each mounting slot 230 is installed with a single cell 220, and a heat dissipation duct 201 is formed between two adjacent columns of single cells 220. Specifically, each mounting slot 230 on the frame 211 is adapted to the shape of the single cell 220, so that the single cell 220 can be installed firmly. For example, two columns of single cells 220 are arranged inside the battery box 200, and the gap formed between the two columns of single cells 220 is the heat dissipation duct 201, through which cold air can pass to blow out the heat generated by the two columns of single cells 220.

[0039] Continue reading Figures 7 and 8 Further, the fixing frame 210 includes a frame body 211, an upper cover plate 212 disposed on the upper side of the frame body 211, a front cover plate 213 disposed on the front side of the frame body 211, and a rear cover plate 214 disposed on the rear side of the frame body 211. An exhaust fan 240 is installed on the front cover plate 213 corresponding to the heat dissipation duct 201, and an air hole 215 connecting the heat dissipation duct 201 and the second air passage 120 is opened on the rear cover plate 214. By arranging the exhaust fan 240 at one end of the heat dissipation duct 201, power can be provided to the hot air of the heat dissipation duct 201, and the cold air of the first air passage 110 can be quickly pushed into the heat dissipation duct 201, and the heat of the single battery 220 in the frame body 211 can be taken away.

[0040] See also Figures 9 and 10 Furthermore, the exhaust fan 240 is directly opposite to the middle position of the heat dissipation air duct 201. In addition, the heat dissipation air duct 201 can also be arranged at the upper part or the lower part of the heat dissipation air duct 201. By arranging the exhaust fan 240 at the middle position of the heat dissipation air duct 201, the cold air is pushed more evenly.

[0041] See also Fig.12 , further, the area of ​​the air outlet of the converging cover 500 is larger than the area of ​​the air inlet of the converging cover 500. Such a configuration facilitates the diffusion of cold air at the outlet, thereby improving the heat dissipation effect. In this embodiment, the converging cover 500 can be configured to include a first wind cover and a second wind cover that are connected and communicated with each other, the first wind cover has an air inlet on a side facing away from the second wind cover, and the second wind cover has an air outlet on a side facing away from the first wind cover. The air outlet area of ​​the second wind cover can be configured to be larger than the air inlet area of ​​the first wind cover.

[0042] See also Figures 9 and 10Furthermore, mounting strips 250 are provided on opposite sides of the frame 211, a first slot 216 is provided on the front cover 213, and the front cover 213 is assembled to the frame 211 by inserting the mounting strip 250 into the first slot 216, and a second slot 217 is provided on the rear cover 214, and the rear cover 214 is assembled to the frame 211 by inserting the mounting strip 250 into the second slot 217. With such a configuration, when assembling the front cover 213, the first slot 216 of the front cover 213 is aligned with the mounting strip 250 on the frame 211 and slidably inserted; when assembling the rear cover 214, the second slot 217 of the rear cover 214 is aligned with the mounting strip 250 and slidably inserted. In this way, the installation structure of the battery box 200 is simple, and the assembly process is simplified. Of course, in order to strengthen the effect of fixing the frame body 211 by the front cover plate 213 and the rear cover plate 214 , screws may be used to cover the front cover plate 213 and the rear cover plate 214 on the front and rear sides of the frame body 211 , respectively.

[0043] See also Figure 4 and Figure 6 Furthermore, the energy storage battery cabinet also includes an inverter 300, which is electrically connected to a plurality of single cells 220, and the inverter 300 is arranged on the battery box 200 and arranged at the third air duct 130. The arrangement of the collector 500 can ensure that the cold air blown out from the cold air outlet 420 of the air conditioner 400 can be directly and preferentially transported to the third air duct 130 and the first air duct 110 without passing through the second air duct 120, so that the cold air can quickly fill the battery cavity 101 of the cabinet 100 and then circulate back to the hot air inlet 410 of the air conditioner 400, preventing the cold air inside the cabinet 100 from failing to reach some locations that need cooling, thereby enhancing the heat dissipation effect. The flow path of the cold air is: cold air outlet 420, air inlet, air outlet, third air duct 130, first air duct 110, heat dissipation duct 201, second air duct 120, hot air inlet 410, and then reflux to the cold air outlet 420.

[0044] See also Figure 5 Furthermore, the cabinet 100 is provided with a plurality of mounting plates 102 in the battery cavity 101, the plurality of mounting plates 102 are arranged at intervals, and the plurality of mounting plates 102 are used to mount and support a plurality of battery boxes 200 and inverters 300. The structure of the mounting plates 102 may be similar to an "L"-shaped arrangement, and the battery boxes 200 and inverters 300 may also be fixed thereon with screws.

[0045] See also Figure 1 Furthermore, the air conditioner 400 is installed naked on the side of the cabinet 100 and is exposed outside the cabinet 100. In this way, the air conditioner 400 is wall-mounted on the side of the cabinet 100, which reduces the internal space occupied by the cabinet 100, reduces the volume of the cabinet 100, and can cool the single battery 220 in the cabinet 100.
