There are some special products that require waterproof fans, such as refrigerators, outdoor cabinets, humidifiers, bathroom products, car lights, etc., and different products have different requirements for waterproofing. The requirements are lower, we generally call it moisture-proof, and the motor stator , PCB board is dipped in conformal paint for protection, as shown in Figure 1. u003cbru003e u003cbru003e u003cbru003e    For products with high waterproof requirements, it is even possible to soak in water or immerse in water. The requirements for waterproof fans need to reach IPX7. It is not acceptable to use moisture-proof plus three-proof paint protection. The motor is completely isolated so that the water cannot interfere with the motor. The more reliable method is: add glue to the PCB and seal the motor, so that the motor cannot be seen. u003cbru003e u003cbru003e u003cbru003e    This kind of waterproof fan needs a special mold to add waterproof function, the internal structure is designed to be glued, and the motor plus special mold protection cover. It also requires a professional model. To do this process is to put the waterproof fan in the water to work, without affecting the fan performance
