Definitions

  • the present invention relates to an axial fan according to the preamble of claim 1.
  • Such axial fans are used for air cooling of heat generating components. Above all, they are used as computer fans for air cooling of electrical and / or electronic components in personal computers or computers. They include a fan housing with an axiallyteurströmbaren Lucasleitrahmen in which a fan is rotatably mounted, wherein the fan housing in the axial direction has an at least substantially rectangular cross-section and in its four corners with fastening means for direct attachment to a component to be cooled or for indirect attachment is provided on a housing containing the component to be cooled.
  • the fastening means are formed by mounting holes which are arranged at a standard distance such that the fan can be fixed by means of screws in the computer housing also provided in the standard distance holes.
  • the fastening means can also be designed for other types of fastening, for example for snap connections
  • Such axial fans which are also referred to as case fans, are well known. They are used in particular in computers for cooling or for dissipating the heat that is emitted by heat-generating components, for example, processors, in particular via heat sinks. This is done by rotation of appropriately shaped with blades or
  • Fan blades provided fan cooling air flow generated, which is directed in at least substantially axial direction on the heat-emitting and to be cooled component.
  • the fan can also be arranged so that it sucks the ambient air surrounding the heat-dissipating member, so as to dissipate the heat.
  • Such fans can also be used on other chips, in particular graphics cards, hard disk drives and / or power supplies.
  • such fans can be used in other devices with heat-generating components, such as projectors.
  • Fans of the type mentioned thus basically consist of two main main assemblies, namely the fan housing and the rotatable fan wheel unit connected thereto. While the fan housing with its outer areas or with its Luftleitrahmen the installation of the ready-to-use fan, the fan wheel unit ensures with their fan blades by their rotation for the desired movement of the air.
  • the rotational movement of the fan wheel unit is usually brought about by an electric motor arranged coaxially with the fan wheel in or on the fan housing.
  • the mechanically transmitted to the fan housing during operation oscillations or vibrations increase the overall volume of the fan depending on the speed considerably, since the fan housing of the fan forms a resonator.
  • the fan is mounted in a computer housing, usually made of sheet steel, which is usually done by a fixed snap or screw connection, the vibrations are transmitted to the then resonating computer case, which again increases the volume.
  • the vibration transmission to the computer case is carried out by the direct contact of the vibrating plastic parts of the fan housing with the computer case. Since a computer housing is a very good sound box, the high-frequency vibrations (structure-borne noise) caused by the fan are clearly audibly amplified by the PC housing.
  • the fan is not fastened with metal screws, but attached as a separate mounting means additionally and specially shaped rubber elements, which should prevent the transmission of the fan vibrations to the computer case.
  • Another disadvantage is the additional installation space required for the elastomer components located outside of the fan housing, which represents a considerable problem, especially in the cramped space conditions in a computer housing.
  • Object of the present invention is therefore to provide an inexpensive to manufacture and easily assembled without additional components fan of the type mentioned above, which has a significantly improved noise reduction in a structurally simple way and is very quiet in operation, without requiring additional space.
  • Essential in the solution according to the invention is that at least one elastic damping element is integrated into the axial fan, which is arranged such that it is effective between the fan and the attachment means for fixing the axial fan.
  • a significant advantage lies in the fact that due to the effective between the fan and the attachment means for fixing the axial damping damping element, the fan or the Lüfterradö decoupled as a vibration-generating component mechanically completely from a serving for mounting the fan component, in particular from a computer housing receiving the fan is. Therefore, vibrations or vibrations that arise can no longer or at most be transmitted to a significantly reduced extent to an outer component or to a computer housing. Outer components or computer cases are therefore no longer amplifying the resonant body, whereby the volume of the fan during operation is considerably reduced. In particular, in perceived as annoying frequency range as a significant noise attenuation can be achieved.
  • Another significant advantage is that due to the complete integration of the at least one damping element or the complete integration of all damping elements in the fan neither additional space nor separately to be mounted elastomeric elements are needed. All damping elements are located in the fan housing, so that the axial fan according to the invention can be mounted or attached in exactly the same way and used by the user, as the conventional fan without integrated damping elements.
  • an axial fan is created, which not only runs very quietly, but is also inexpensive to produce and quick and easy to install.
  • all the damping elements are integrated into the fan, so that no separate damping components are needed more, via which the fan must be mounted in the computer.
  • the fan according to the invention can therefore be easily mounted in a conventional manner by snap connections or by screw in a computer case, the conventional and standardized mounting holes can be used.
  • All damping means are arranged in the fan housing, on the one hand no additional space is required and on the other hand, an unwanted amplification of the vibrations or an increase in the volume of the fan can be effectively avoided.
  • each fastening means which is used for fastening the fan to a component to be cooled or to a computer housing, is accommodated in a damping element, wherein the damping elements are in turn disposed within the axial fan.
  • the damping elements in the axial direction have a greater length than the Lucasleitrahmen, so that the damping elements axially project beyond the Luftleitrahmen at least one end face. In this way it can be safely prevented that the axial fan or its Heilleitrahmen has direct axial contact with a component or housing to which the fan is attached. Only the elastic damping elements can come into direct axial contact with the component to be cooled or with the computer housing. The transmission of vibrations to a component to be cooled or to a computer housing containing the fan can thus be effectively prevented.
  • the damping elements project beyond the Luftleitrahmen axially on both end faces.
  • the fan can be applied with both end faces axially to a component or a computer case and attached to it.
  • the vibration decoupling can be done regardless of the orientation of the fan during its assembly.
  • the damping elements axially project beyond the Lucasleitrahmen on or on the end face (s) by at least 0.5 millimeters, preferably by at least 1 millimeter.
  • a direct contact of the fan housing with surrounding components or computer housings is particularly reliably prevented.
  • the elastic damping elements are firmly bonded to the Luftleitrahmen, in particular on the outer sides of the Heilleitrahmens.
  • a particularly cost-effective production of the axial fans according to the invention can be achieved.
  • the shipsleitrahmen viewed in the axial direction, at least approximately have an octagonal cross section, wherein the elastic damping elements each have an at least approximately triangular cross-section.
  • the sides facing the damping elements may be rounded or the Lucasleitrahmen may have a total of a round cross-section, wherein the damping elements each have an at least approximately triangular cross-section with a concavely curved base side.
  • the fastening means are preferably formed by bores.
  • self-tapping screws can be used to attach the fan.
  • the mounting holes each received in the respective elastic damping element or cast, preferably made of metal or Plastic existing, threaded sleeve with an internal thread include.

  • the fan wheel is mounted in bearing means which are connected via connecting means to the fan housing, wherein the connecting means comprise a central storage area on which the bearing means and / or the stator of the electric motor by means of at least one elastic damping element are attached.
  • bearing means fans and / or roller bearings, in particular ball bearings, are preferably used in fans.
  • the bearing means can advantageously also be integrated in the electric motor, so that the bearing means need not be mounted separately but are practically formed by the electric motor. It is also particularly advantageous if the electric motor is designed as a brushless external rotor motor. It is essential in the preferred embodiment of the invention, however, that the bearing means are elastically decoupled from the central storage area, so that vibrations generated by the fan can not or at most attenuated transmitted to the fan housing.
  • the rotor or the rotating magnets of the electric motor can also be arranged in the radially outer region of the fan wheel, so that the stator or the coils of the electric motor are located radially outside the fan wheel.

  • the connecting arms can be arranged in any shape, orientation and number. It is particularly advantageous if at least one elastically resilient damping element, preferably centrally, is formed in each connecting arm.
  • Essential in the second and third particularly preferred embodiment of the invention is that for vibration damping all connecting means between the fan housing and the bearing means each comprise at least one elastically resilient damping element.
  • a significant advantage lies in the fact that due to the damping element present in each connecting element, the fan housing is completely mechanically decoupled from the fan wheel unit. Therefore, resulting vibrations or vibrations can not be transferred to the fan housing any more or at most to a significantly reduced extent. Therefore, even the fan housing is no longer amplifying the sound volume resonance body, whereby the volume of the fan during operation is significantly reduced. In particular, in perceived as annoying frequency range a significant noise attenuation can be achieved in this way.
  • a particularly quiet operation is advantageously also achievable in the second and third preferred embodiment of the invention, when the bearing means are connected in the axial direction and in the radial direction and in the circumferential direction of rotation elastically movable with the fan housing, so that no more mechanically rigid connection between the fan housing and the bearing means for the Lüfterradü is given.
  • the noise damping can be further increased by the fact that in the connecting means a plurality of series or series-arranged resilient or rubber-elastic damping elements are integrated into the fan.
  • the elastically resilient damping elements made of rubber or rubber material or of an elastically resilient plastic, in particular made of polyurethane.
  • Plastic spring elements can preferably be formed by a wave-shaped and / or zigzag-shaped region, which can be particularly easily formed in a connecting arm between the central storage area and the fan housing.
  • the fan has fan blades whose surface is provided on one side or on both sides with a plurality of small local elevations and / or small local depressions, in particular with dome-shaped indentations.
