Any formalCooling fan manufacturers, will clarify the working temperature, storage temperature, and dry humidity of the cooling fan in the product specification. Jingyangda Technology orders the cooling fan for each customer. The working temperature is usually -10~70 ℃, and some special The ambient temperature is lower, is there any way?

Regarding the environment with low humidity, special ball bearings are adopted, and the low temperature can reach -40 ℃. If the humidity causes water to freeze, then there is no way to turn the heat dissipation fan. When the heat dissipation fan is abnormal, for example, it does not turn and is noisy, we want to find out, but how to turn it over? First, we must separate the rotor from the stator to separate the heat dissipation fan with oil bearing and double ball bearing, just remove the clasp and the leaves can be taken out.

However, hydraulic bearings are relatively difficult to disassemble. Most of them cannot be disassembled. If no problem is found and the PCB board of the heat dissipation fan needs to be further disassembled and analyzed, the regular heat dissipation fan can be pulled out only by taking the bearing out of the stator. The general specification of the heat dissipation fan will indicate that the temperature is between -10 and 70 degrees. Since the regular heat dissipation fan in this interval is relatively reliable, someone will ask, does the data of the cooling fan only accept high temperature 70 degrees?

In fact, the temperature that the data can accept is more than that. For example, IC can accept 80 degrees, plastic parts can accept 110 degrees, wires can accept 80 degrees, and motor copper wires can accept 110 degrees. However, we know that when the cooling fan is running, the motor itself will generate heat. The higher the current, the higher the temperature rise. Therefore, the temperature of 70 degrees in the environment is definitely more than 70 degrees, can be designed at 85 degrees, using high temperature resistant 100 degrees drive IC, 160 degrees resistant motor copper wire, 180 degrees resistant wire, plastic parts using fireproof materials.

The above is the temperature requirements of the cooling fan. For more information, please consult our official website!
