[0002] At present, the existing humidifying mode generally adopts two kinds, electrode humidification and wet membrane humidification.

[0003] The electrode humidifier generally adopts electrode humidification, which is to inject water vapor directly into the air to humidify. This method is prone to incomplete atomization, resulting in the presence of liquid water in the air. These liquid water will affect product quality if they come into contact with indoor products for a long time.

[0004] The wet membrane humidifier is placed outdoors in winter, and the water in the water pan will freeze due to the low temperature environment, so it can only be placed indoors. However, when placed indoors, liquid water leakage may occur when a fault occurs, and the use in the machine room is more likely to cause a major accident.

[0008] Further, the water spraying device adopts a U-shaped overflow water distribution mode to uniformly distribute water to the wet membrane.

[0009] Further, a float ball valve is arranged in the water pan.

[0010] Further, a plurality of ventilation holes are arranged on the partition plate.

[0011] Further, the maintenance surface on the shell is a movable maintenance plate, and the frame of the shell is made of 4028 aluminum alloy edge strips.

[0012] Compared with the prior art, the utility model has the beneficial effects of

[0013] 1) the utility model discloses a wet membrane humidification method is adopted to the structure, can be placed in the outdoor.

[0014] 2) the utility model discloses the wet membrane humidification directly vaporizes liquid water, and the phenomenon such as dew condensation white mist does not appear, and the humidification effect is more thorough and more uniform, can effectively avoid the liquid water in the air.

[0015] 3) the device is wound with the electric heat tracing band on the water tray surface, can be placed in the outdoor, even if the failure also does not influence the normal work of the computer room. BRIEF DESCRIPTION OF DRAWINGS
