How much do you know about the moistureproof and waterproof methods of micro fans?
Some products are often put outdoors, whether in the sun or in the rain, they need micro cooling fans to work normally. Others need micro fans to work in the humid environment. At this time, they need micro-fans to do moisture-proof and waterproof treatment. Today, the editors of Beijing Electric Power Port share with you some methods of moisture-proof and waterproof treatment. Details are as follows.
1. The stator motor contains PCB board and moisture-proof and waterproof Fan Li Shui protective film. The stator of the motor is placed in varnish for 1-3 minutes to make the water-proof Fan Li Shui fully permeate every part of the motor, and then the natural air-drying of the motor stator is taken out. This design has no abnormality in the case of a small amount of drifting rain or water mist.
2. The stator motor does not contain PCB board, which is protected by immersion ruler and vertical water. The PCB board is insulated by a layer of insulation, sealed by glue, and then dried naturally. The fan can be immersed in water and taken out for testing without abnormality.
3. A plastic cover is designed from the die, so that the stator is completely in the cover, and then sealed with glue. This structure can make the fan run in water without abnormality.
