What are the processes for the internal structure of the waterproof fan?

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 protected by immersion three-proof paint, as shown in Figure 1. (Picture 1) For products with high waterproof requirements, it may even be possible to soak in water or immerse in water. The waterproof fan needs to reach IPX7. It is not possible to use moisture-proof plus three-proof paint protection. After the motor is completely isolated, so that water cannot interfere with the motor, a more reliable method is: add glue to the PCB, seal the motor, and the motor cannot be seen, as shown in Figure 2 and Figure 3 (Figure 2) (Figure 3). All waterproof fans need a special mold to add waterproof function. The internal structure is designed to be glued, and the motor is equipped with a special mold to protect the cover. It also requires a professional model. This process is to put the waterproof fan in water to work, and it will not affect the performance of the fan.
