Cooling type Micro Cooling Fan features

   When the electronic "Micro Cooling Fan" products due to high temperature impact performance, we first will consider adding a miniature fan assisted cooling, but the AC fan is good, or good DC fan, which became a problem, let Let's analyze
   1, DC fans can take DC 5V, 12V, 24V, etc. AC fan directly connected to the mains 220V, 240V, 110V,
   2. DC brushless "Micro Cooling Fan" is generally used plastic frame, small motors use less copper, low material cost, AC fans are brush motor, the stator part of a large, multi-copper, aluminum frame multi-purpose, cost much higher,
   3, big DC fan blades, the greater the amount of wind, AC fans for its small leaves, a small amount of wind
   4. DC "Micro Cooling Fan" and longer life
   5, the DC voltage from the fan safety considerations, no danger
