The design principle of the system air duct is as follows:

without BBU device 4: the ventilation opening 11 is kept in a closed state, and the corresponding slots of the two side air duct plates 100 are provided with two dummy panels 500 for sealing, one dummy panel 500 is fixed between the first support column 110 and the second support column 120, and the other dummy panel 500 is fixed between the third support column 130 and the fourth support column 140, so as to isolate the cold air duct from the hot air duct.

When loaded into the BBU device 4: two dummy panels 500 corresponding to the slots are removed, the limiting parts 5 arranged on the first limiting holes 321 and the second limiting holes 14 in a penetrating mode are removed, when the BBU equipment 4 is inserted, the back face of the BBU equipment 4 is attached to and attracted by the magnets 361 of the outer sliding plates 3 of the two side air duct plates 100, and the outer sliding plates 3 of the two side air duct plates 100 move synchronously with the BBU equipment 4 along with the insertion of the BBU equipment 4; when the BBU equipment 4 is inserted to a proper position, the outer-layer sliding plate 3 and the inner-layer sliding plate 2 synchronously stop moving, the outer-layer sliding plate 3 and the back surface of the BBU equipment 4 are in a fit state, and at the moment, the ventilation openings 11 on the two side air duct plates 100 are opened, so that the air inlet and the air outlet of the BBU equipment 4 can be the same as the ventilation openings 11 to form a system air duct; taking the first BBU device 41 as an example, the first air guide 200 isolates the cabinet body of the BBU concentration cabinet into a front space, a rear space, a left space and a right space, cold air enters from the front space, the cold air flows to the left space through the first air guide 200, then enters from the left air inlet 411 on the left side of the first BBU device 41, hot air is discharged to the right space from the right air outlet 412 of the first BBU device 41, and then the hot air flows to the rear space through the first air guide 200.

When the BBU device 4 is taken out: the outer sliding plate 3 moves together with the BBU equipment 4, the outer sliding plate 3 drives the inner sliding plate 2 to slide together, and finally the side air duct plate 100 is restored to the state without the BBU equipment 4.

The system air duct design of the invention solves the problem of mutual channeling of cold and hot air flows in the BBU centralized cabinet, and has simple operation.

Further, referring to fig. 11 to 14, as a specific embodiment of the BBU centralized cabinet provided by the present invention, the first wind guide 200 and the second wind guide 300 are both of a cavity box structure; a first partition plate 210 is arranged in the first air guide 200, the first partition plate 210 divides the interior of the first air guide 200 into a first cold air channel 211 and a first hot air channel 212, the first cold air channel 211 is communicated with a left air inlet 411 of the first BBU device 41, and the first hot air channel 212 is communicated with a right air outlet 412 of the first BBU device 41; a second partition plate 310 is arranged in the second air guide 300, the second partition plate 310 divides the interior of the second air guide 300 into a second cold air channel 311 and a second hot air channel 312, the second cold air channel 311 is communicated with a right air inlet of the second BBU device, and the second hot air channel 312 is communicated with a left air outlet of the second BBU device.

Illustratively, the first air guide member 200 and the second air guide member 300 of the present invention have the same shape, and the second air guide member 300 is a reverse structure of the first air guide member 200. The BBU centralized cabinet provided by the invention can flexibly configure the first air guide piece 200 and/or the second air guide piece 300 according to the air inlet and outlet modes of left cold air inlet, right hot air outlet or right cold air inlet and left hot air outlet of the BBU equipment 4, thereby separating and forming a cold channel and a hot channel. The first partition plate 210 divides the inside of the first air guide 200 into a first cold air channel 211 and a first hot air channel 212, the second partition plate 310 divides the inside of the second air guide 300 into a second cold air channel 311 and a second hot air channel 312, the first cold air channel 211 is communicated with the second cold air channel 311, the first hot air channel 212 is communicated with the second hot air channel 312, and cold air and hot air in the BBU concentration cabinet are separated to form the cold channel and the hot channel.

Further, referring to fig. 9 as a specific embodiment of the BBU centralized cabinet provided by the present invention, the BBU centralized cabinet further includes a plurality of wind deflectors 400; the wind deflector 400 is secured between the first and

fourth struts

110, 140, and the wind deflector 400 is secured between the second and

third struts

120, 130; and the wind deflector 400 is fixed to one side surface of the first wind deflector 200 and/or the second wind deflector 300.

The air baffles 400 seal cold air of the first cold air channel 211 communicated with the left air inlet 411 of the first BBU equipment 41 to form a first cold negative pressure cavity, and the air baffles 400 seal cold air of the second cold air channel 311 communicated with the right air inlet of the second BBU equipment to form a second cold negative pressure cavity; the wind deflector 400 is disposed between the left side wall of the first air guide 200 and the left side wall of the second BBU device, so that the first cold air channel 211 is isolated from the second hot air channel 312, and the wind deflector 400 is disposed between the right side wall of the second air guide 300 and the right side wall of the first BBU device 41, so that the second cold air channel 311 is isolated from the first hot air channel 212.
