Abstract

A cooling fan includes a bearing system having upper and lower bearings axially arranged in a central tube of a frame of a fan. Each bearing has a central hole and a groove formed on an outer periphery thereof. First and second spaces are defined respectively at a top end of upper bearing and a bottom end of the lower bearing. A third space is defined between the upper and lower bearings. These spaces communicate with each other through the holes and grooves of the bearings.
