220V Cooling Fan design

In addition to "220V Cooling Fan" design itself, the selection of the basic determinants, as stated above, the use of the environment will result in a significant impact on the life of the fan. High temperatures accelerate the volatile oil-bearing lubricating fluid, so that the device expansion to increase friction, so that the coil resistance increases, increasing the temperature of the heat into a vicious cycle, accelerating the aging of electronic components. Severe temperature changes "220V Cooling Fan" will make the device deformed so severe contraction Bengduan coil, so that the semiconductor device operating point drift. Dust will make changes in the distribution of quality blades, increasing friction, air resistance increases, the impact of its own heat, hinder fins and air heat exchange, resulting in electrostatic discharge damage to the components and equipment. "220V Cooling Fan" adverse environmental conditions may cause the fan effect of greatly reduced, and greatly reduced life expectancy.
