The blower 400 is arranged in the third shell 300, and the air outlet end of the blower 400 is penetrated through the second air outlet 320 and connected to the inner wall of the second air outlet 320. It can be understood that the blower 400 is arranged in the third shell 300, and the air outlet end of the blower 400 is connected to the outside through the second air outlet 320 on the third shell 300 and the first air outlet 140 on the first shell 100. After the blower 400 is started, it starts to suck the gas in the third shell 300, so that the cavity in the third shell 300 and the cavity between the third shell 300 and the first shell 100 form a negative pressure, so that the external gas can pass through the first air inlet 110 and the third air inlet 310 in turn to continuously enter the third shell 300; then the blower 400 pressurizes the sucked gas and sends it out of the first shell 100 through the air outlet end of the blower 400. In the utility model, a second air inlet 120 is also opened on the first shell 100, and the split high-speed centrifugal fan also includes a second louver 121 and a second insect-proof net. The second louver 121 and the second insect-proof net are both connected to the first shell 100, and the second louver 121 and the second insect-proof net are both used to block the second air inlet 120.

[0050] During the actual use of the split high-speed centrifugal fan, a small amount of liquid will pass through the first louver 111 and enter the first housing 100. In the present utility model, the third air inlet 310 of the third housing 300 is provided on the side wall away from the first air inlet 110, which makes the path required to move from the first air inlet 110 to the third air inlet 310 longer, so that the liquid and particles entering the first housing 100 from the first louver 111 will be deposited on the lower inner wall of the first housing 100, and the liquid and particles cannot pass through the third air inlet 310 to enter the third housing 300, thereby avoiding damage to the blower 400 caused by the liquid and particles. In the present utility model, a plurality of drainage holes are provided on the bottom wall of the first housing 100, and the plurality of drainage holes are used for liquid to pass through. It can be understood that the liquid deposited on the lower inner wall of the first housing 100 can be discharged to the outside of the first housing 100 through the plurality of drainage holes, thereby avoiding the deposited liquid from affecting the blower 400. On the other hand, the deposited particles may also pass through the plurality of drainage holes and fall out of the first housing 100 .

[0051] refer to Figure 7The split high-speed centrifugal fan further includes a mounting plate 210, which is disposed in the second housing 200, connected to the bottom wall of the second housing 200, and arranged at an angle, and is used for connecting electronic components.

It can be understood that after the blower 400 is started, a negative pressure is formed in the inner cavity of the first housing 100, and since the inner cavity of the second housing 200 is communicated with the inner cavity of the first housing 100 through the ventilation hole 220, a negative pressure is formed in the inner cavity of the second housing 200, and the gas in the second housing 200 can be sucked into the first housing 100 and form an airflow at the ventilation hole 220, and the formed airflow can reduce the temperature of the electronic components on the mounting plate 210 during operation.

[0053] refer to Figure 1 The split high-speed centrifugal fan further includes a support bracket 150, which is connected to the first housing 100. The support bracket 150 is disposed below the first housing 100. The first housing 100 is in contact with the ground through the support bracket 150, and the gap between the support bracket 150 and the ground can be used for the fork of a forklift to pass through. It can be understood that the first housing 100 is in contact with the ground through the support bracket 150, and the fork of the forklift can extend into the gap between the support bracket 150 and the ground, so that the forklift can lift the split high-speed centrifugal fan. As an embodiment of the utility model, a plurality of lifting rings 250 are provided on the second housing 200.
