Abstract
An improved structure of rotation support of heat-dissipation fan comprising ceramic hollow tube bearing passes through and fixes on fan rotor and rotating with rotor, hollow or solid ceramic axle tube passes through the inside of bearing and rotating freely or fixed to fan body to provide low friction and high speed rotation. Exterior surface of bearing is formed or ground to provide better connection with rotor body while interior of bearing and exterior of axle tube are further processed to reduce surface contact area thereof lower rotational friction. This improved structure has achieved lower friction, lower noise, lower power consumption, longer life and higher speed.

A rotation support of heat dissipation fan comprising:
- a hollow ceramic tube bearing, said bearing passes through and fixes on fan rotor and rotating with the rotor;
- a hollow ceramic tube support bearing, said bearing fixes on fan base and works as structural support which do not rotate;
- a solid or hollow ceramic axle tube, said axle tube is cylindrical shape or with an end flange portion forming a T shape tube, said axle tube passes through the inside of said bearing and said support bearing and rotating asynchronously and slowly with rotor, said axle tube works as structural support to provide multi-point contact rotating support mechanism;
- and, a ceramic holding ring with opening gap, said ring limits the axial movement of said axle tube.
A rotation support of heat dissipation fan comprising:
