The installation position of the wet curtain component is arranged on the machine body, the wet curtain in the wet curtain component 40 and the wet curtain support are placed into the installation position after being preassembled, and then the filter screen is buckled on the machine body to limit the wet curtain. When the wet curtain assembly works, water in the water tank is conveyed to the wet curtain assembly 40, flows onto the wet curtain through the water distribution holes, flows into the water collection tank below through the water drainage holes, and flows back to the inside of the water tank through the water collection tank.

The cooling fan further comprises a base 50 fixedly connected to the top of the water tank 10; the body 20 is rotatably coupled to the base 50. The base is used for mounting the body 20 and receiving the connection between the body 20 and the water tank. The base 50 is detachably connected to the water tank 10, and the base 50 and the water tank are fixed. Although the base is fixedly connected (in a connection mode such as threaded connection, clamping connection and screw connection) on the water tank 10, the base can be detached from the top of the water tank 10, and when the machine body and the water tank need to be separated, the base can be directly detached. The body 20 is reciprocally rotated left and right on the base 50.
