The first partition board 1 and the second partition board 2 extend along the first horizontal direction, the first partition board 1 is connected with the first side wall and the second side wall, the second partition board 2 is also connected with the first side wall and the second side wall, so that a first cavity 3 is formed between the third side wall and the first partition board 1, an air inlet cavity 4 is formed between the first partition board 1 and the second partition board 2, and a second cavity 5 is formed between the second partition board 2 and the fourth side wall.
In another alternative embodiment, the second partition plate 2, the second impeller 11 and the second motor 14 are not arranged in the integrated fan shell, namely, only the first cavity 3 and the air inlet cavity 4 are arranged in the shell, and the second cavity 5 can be determined whether to be arranged according to the requirements of a production site.
The middle part of first lateral wall is provided with air intake 6, and air intake 6 and intake cavity 4 intercommunication. Square flanges are arranged at the air inlet 6 so as to be convenient for being installed with an external pipeline. An air inlet 6 is formed by arranging the air inlet cavity 4, so that air flow can flow into the air inlet cavity 4 from the air inlet 6.
The first partition plate 1 is provided with two first communication holes arranged at intervals in the vertical direction, and the first communication holes are used for communicating the first cavity 3 with the air inlet cavity 4. The axes of the two first communication holes are parallel to the second horizontal direction. The second partition plate 2 is provided with two second communication holes arranged at intervals in the vertical direction. The second communication hole is used for communicating the air inlet cavity 4 with the second cavity 5. The axes of the two second communication holes are parallel to the second horizontal direction. So that the air flow in the air inlet cavity 4 can flow into the first cavity 3 and the second cavity 5, respectively.
