Due to its material and bearing, the DC fan is indeed affected by the environment and working pressure. If the DC fan operates in a high temperature operating environment, it will accelerate the evaporation of the lubricating fluid in the oil-impregnated bearing, causing the equipment to expand and cause conflicts, coil resistance. It also increases, entering a vicious circle of heat and hot, which will speed up the aging of electronic components. The service life of the DC cooling fan will be greatly reduced.

The dust will change the mass distribution of the fan blade, increase the conflict, increase the wind resistance, affect its own heat dissipation, make the heat transfer between the heat sink and the air difficult, and cause electrostatic discharge to damage components and equipment. Bad use environment may greatly reduce the effect of the fan, and greatly reduce the lifespan. If the working pressure of the cooling fan is high, the faster the fan rotates, the faster the bearing wears, the more heat the stator winding coil and electronic components are, and the longer the service life is.

Therefore, the temperature of the surrounding environment has a great impact on the life of the DC fan, so we usually pay more attention to the maintenance and maintenance of the DC fan. In the summer of high temperature, try to take ventilation fan measures for the mechanical equipment, and the second is to buy New products of high-quality DC fans, low-quality DC fans will not only affect production, but also cause unnecessary trouble.
