DC cooling fanIts own characteristics, unlike other products, DC cooling fan is active stirring air, accelerate the air flow, so, at the same time also inhaled dust. There are two main aspects of inhaling dust, one is inhaled into the bearing, and the other is inhaled into the rotor and stator. The inhaled dust has more or less an impact on the cooling fan. The common practice is generally from the following two aspects.
1. When designing, the place where the motor is installed in the outer frame should be raised to allow the motor to sink, reduce the distance between the stator and the rotor, and reduce the dust entering.
2. Using double ball bearings, the ball has a certain dustproof ability, the bearing is not easy to be seriously interfered.
In addition to the above two aspects of dust protection from the cooling fan itself, adding a dust net to the fan is also a very effective way. Because the amount of cooling fan with dust-proof design is small, most manufacturers do not have such molds, so it is more desirable to add dust-proof net without opening the mold.

For DC cooling fan manufacturers, let the fan can play ventilation, heat dissipation is the first factor, but can let the cooling fan play its due function for a long time, that is, reliability, which is an important factor to measure the strength of a cooling fan manufacturer, the reliability of the cooling fan will consider the following factors.

1. Temperature rise: ambient temperature, the temperature of the motor itself, and the temperature rise of the general motor does not exceed 110 degrees during operation).
2. Current: It is necessary to fully consider the bearing capacity of the chip. During design, the actual current will be lower than the nominal current of the chip.
3. Withstand voltage: For the voltage stability of the customer's products and the withstand capacity of the cooling fan voltage, some product voltages are not stable and will be high.
4. Anti-interference: For some products, the environment where the cooling fan is installed has strong static electricity, and the cooling fan needs to be protected.
5. Waterproof: Some products deal with humid environments or work in water, we need to consider the waterproof level of the cooling fan.
The above five are the reliability factors to be considered by the cooling fan itself. In addition to these, there are also some installation factors, odor factors and other cooling fans that need to be adjusted. When the customer proposes it, we will take corresponding measures.
The above is the dustproof and reliability of the DC cooling fan. For more information, please consult our official website online customer service!
