Date: 2015-5-20   Click: 1645 Times

Understanding "Tiny Cooling Fan" a little common sense, the optoelectronic industry require high temperature and cooling fan ultra-quiet! Now I introduce Shenzhen Heng good fan cooling fan photovoltaic industry several elements!
  High temperature bearings and motor section to achieve the following five points:
  1, the poor quality of the lubricant, used in an amount insufficient, so that the message part is not in direct contact friction, the friction is formed between a solid and a liquid. If an insufficient number of oil or poor quality, will make the message part of the direct friction heat, or heat can not be taken away by the lubricating oil, leaving the bearing temperature rise;
  2, "Tiny Cooling Fan" poor quality of the bearing assembly is rotated, rain jacket bearing gap is too large or too small;
  3, the quality of the bearing not rotating bearing rotation decent cracks, chipping, peeling, etc., will undermine the stability and uniformity of the film, the surface of the bearing fever;
  4, sealing felt too tight cause fever;
  5, "Tiny Cooling Fan" bearing vibration is too large, too much pressure.
