Fan for e.g. microprocessor of computer system, has fan blade extending radially outwards from rotor units inclined to rotation axis, where free end of blade opposite to rotor units is curved downwards in direction of air suction side

摘要

The fan (1) has a drive unit, which consists of an electromotor with a fixed stator and a rotor movably supported around a rotational axis relative to the stator. A fan blade (5) is arranged at a circumference of rotor units (4) connected with the rotor. The blade extends radially outwards from the rotor units inclined to a rotation axis, where the side of the blade facing the rotor forms an air suction side. The free end of the fan blade opposite to the rotor units is curved downwards in the direction of the air suction side. An independent claim is also included for a clamping unit for a fan.
