High-pressure centrifugal fan for heat dissipation has rotor with blades provided in housing such that rotor has extending portion extending along axial direction to form axially compressed air passage inside housing

摘要

The centrifugal fan includes a housing formed with two frames (21,22) having an air inlet (221) and an air outlet. A rotor (25) with two set of blades (253,254) is provided in the housing such that the rotor has an extending portion extending along an axial direction to form an axially compressed air passage inside the housing.
