AI Technical Summary
Technical Problem
Existing heat dissipation fans are prone to bearing electrical corrosion problems at high speeds and high powers, mainly due to spark discharge and grease aging caused by shaft current.
Method used
By providing an insulating portion in the mounting portion of the fan, and connecting the first bearing and the second bearing in conflict with the insulating portion, the electrical circuit between the shaft core, the bearing and the metal pipe is destroyed, and a ceramic shaft core is used to further reduce the risk of electrical corrosion.
Benefits of technology
It effectively reduces the risk of bearing electrical corrosion, avoids early bearing failure and increased fan vibration noise caused by electrical corrosion, and reduces production costs and assembly complexity.
