Dc waterproof fan is a special kind of fan, it has waterproof grade IP55, IP68, can work under water, salt, oil, corrosion environment. This fan is commonly used in industrial power supplies, medical equipment, communication cabinets and other fields to provide heat dissipation and ventilation. The working principle of the DC waterproof fan is to rotate the fan blades through the DC power supply, thus generating air flow. The advantages of DC waterproof fans are low efficiency but low cost, and can be directly connected to the mains, and the service life is not much different from that of DC fans. In addition, some DC waterproof fans also have a sensitive temperature sensor built in, which can achieve the revolution and current change with the temperature, so that the heat dissipation effect is optimal.
