Can the cooling fan be waterproof after adding lubricating oil? There are two real waterproof methods, one is to vacuum coat the motor to make it sealed and then achieve the waterproof effect, the second is to use A and B resin to seal the motor, the effect is better, but The process is more responsible and the cost will be higher. However, many cooling fan manufacturers choose to add lubricating oil to waterproof, is this really waterproof? Today, Fanshuo electronic cooling fan manufacturers will give you a brief answer.
Refueling has no effect on waterproofing. The reason is that the primary effect of lubricating oil is to reduce the conflict between parts. He can only say that it is insoluble in water, so it does not really have a waterproof effect. The cooling fan should be waterproof. Generally, the stator, that is, the motor, including the PCB board is wrapped with a special glue to prevent water from entering the motor. Just like the two methods I mentioned above, I will remind the buyer that when buying a waterproof cooling fan, you must figure out which method the manufacturer chooses to complete the waterproofing.
