Now, to have the ability to execute these and nevertheless even more objects belonging to the invention, that will come to be more readily apparent since the explanation proceeds, the axial lover according for the invention comprises a motor unit, a rotatable lover blade device drivenby stated motor unit, stated lover blade device comprising a lover mind and a plurality of lover blades arranged radially to stated lover head, facilitates for holding stated motor unit, stated facilitates extending through an airflow created by stated lover blade unit, wherein thesupports have a range d of at the least 7.5 mm from the lover blades measured in an axial direction.
In an additional element belonging to the invention the axial lover for any pc comprises a static frame, a motor unit, a lover mind driven by stated motor device for rotation about an axis of rotation, lover blades connected radially to stated lover mind and becoming rotatedby stated lover mind for producing an airflow, and facilitates connecting stated static frame to stated motor unit, stated facilitates extending through stated airflow, wherein the facilitates have a range d of at the least 7.5 mm from the lover blades measured parallel tosaid axis of rotation.
In the traditional axial lover discussed herein, the range between the facilitates and also the lover blades is mostly only two to three mm. The invention is based for the insight that the disturbing buzzing sound experience belonging to the traditional Axial fan is induced byturbulence effects during the areas, by which the lover blades pass closely along the facilitates to the motor unit. This insight could be confirmed through the actuality that the disturbing buzzing sound experience does not take place at radial fans. At these there are, in contrast tothe Axial fan, because belonging to the geometry, no facilitates during the oxygen flow necessary. By an enlargement belonging to the range between the facilitates and also the lover blades the turbulence effects described above and also the buzzing sound experience which comes with it are avoided or atleast reduced. Thereby, the invention is heading in the path opposite for the general craze of advancement during the field of laptops to design and style all models as small as possible. However, retrospectively searching at it, the benefit belonging to the sound experience reductionoutweighs the disadvantage belonging to the slightly bigger dimensions belonging to the fan. In specific situations the bigger dimensions are not even a disadvantage, since the room additionally used should be kept 100 % free to the incoming flow in the regarded options anyway, asdescribed even more lower beneath referring to FIGS. three and 4.
