Ordinary cooling fan manufacturers have specified the operating temperature, storage temperature, and dry humidity of the cooling fan in the specification. , Some special ambient temperatures are lower, is there a way?
For environments with low humidity, special ball bearings are used, and the low temperature can reach -40°C. If the humidity causes water to freeze, then the cooling fan will not be able to rotate. When the cooling fan is abnormal, for example, it does not rotate and the noise is loud. , We want to find out, but how to open it, first of all, we need to separate the rotor and stator to separate the cooling fan with oil bearing and double ball bearing, just remove the snap ring, and the leaves can be taken out.
The hydraulic elbow bearing is more difficult to disassemble, and most of them cannot be disassembled. If no problem is found, and it is necessary to further disassemble and analyze the PCB board of the cooling fan, it is only necessary to take the bearing out of the stator and it can be pulled out. Conventional heat dissipation The general specification of the fan will indicate that the temperature is between -10 and 70 degrees. Since the conventional cooling fan in this range is relatively reliable, some people will ask, can the data of the cooling fan only accept a high temperature of 70 degrees?
In fact, the acceptable temperature of materials is not limited. For example, IC can generally accept 80 degrees, plastic parts can generally 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 The higher the current, the higher the temperature rise. Therefore, the ambient temperature of 70 degrees + its own temperature must be more than 70 degrees. The special high-temperature heat dissipation fan can be designed at 85 degrees, and the driver IC with high temperature resistance of 100 degrees is used. 160 degree motor copper wire, 180 degree resistant wire, plastic parts are made of fireproof material.
