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.
- a cooling air flow is generated by rotation of the provided with suitably shaped blades or fan blades fan, which is directed in at least substantially axial direction on the heat-releasing 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 may also be connected to other chips, in particular to graphics cards, to hard disk drives and / or to Power supplies are used.
- 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.
- the fan housing is vibration damping attached to a component or the computer case, whereby a certain noise attenuation can be achieved. It is also known to mount the fan housing freely swinging by means of one or more outwardly tensioned rubber cords.
- 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.
- the GB 2 107 787 A discloses an axial fan with a fan housing surrounded by an external isolation device.
- This isolation device comprises an outer frame and an inner frame, which are interconnected by an elastic membrane.
- the inner frame is either attached by screws to the fan housing or designed in one piece with it, wherein the membrane acting as an elastic damping element is not integrated in each case in the fan housing, but this outside surrounds. This in turn requires additional space and is associated with the disadvantages mentioned.
- 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 manner and is very quiet in operation, without requiring additional space.
- 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 Befest Trentsbohrüngen can be used. Since 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.
- damping elements can project beyond the Luftleitrahmen axially on both end faces of the fan with both end faces axially applied to a component or a computer case and attached thereto.
- the vibration decoupling can be done regardless of the orientation of the fan during its assembly.
- 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 comprise a recorded or cast in the respective elastic damping element, preferably made of metal or plastic, threaded sleeve having an internal thread. In this case, then the internal thread corresponding, in particular metric screws can be used for secure attachment of the fan.
- 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.
- 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 elastically resilient damping elements made of rubber or rubber material or of an elastically resilient plastic, in particular made of polyurethane.
- the present invention furthermore relates to a computer, in particular a PC, which contains a fan according to the invention of the type described above.
- FIG. 1 schematically shown axial fan 1 of conventional design has a manufactured from plastic cuboid fan housing 2, which in each case has a mounting hole as a fastening means 3 for attachment in a computer case, not shown here in the corners of its outer housing portion. From the outer housing portion extending four straight connecting arms 4 inwardly, at its inner End in a circular trained central storage area 5 of the fan housing 1 open.
- the connecting arms 4 extend in the embodiment shown here tangential to the bearing area 5. However, they can also extend in other directions, for example radially. Likewise, the connecting arms 4 can also be bent and / or provided in a different number.
- a fan 6 is rotatably mounted.
- a not-shown electric motor is provided in the fan housing 2, which is arranged completely or partially in or on the hub 7 and the storage area 5.
- the fan 6 is thus connected via the bearing means and the storage area 5 and the connecting arms 4 to the fan housing 2. By its rotation, the fan 6 generates the air movement required for cooling, the outer region of the fan housing 2 serves as Heilleitrahmen for the air flow. In this respect, fans 1 are generally known.
- damping elements 9 are arranged in the four corners of the fan housing 2.
- the damping elements 9 are then vulcanized onto the outer sides of the Heilleitrahmens 10.
- the Heilleitrahmen 10 of the fan housing 2 has viewed in the axial direction on the inside a surrounding the fan 6 round cross section and the outside a substantially octagonal cross-section, the four the Damping elements 9 facing sides 11 are made shorter than the four outer sides of the fan housing 2 forming sides 12th
- the damping elements 9 in the axial direction have a greater length than the Lucasleitrahmen 10 or as the fan housing 2.
- the damping elements 9 have a length of 25 mm, which corresponds to a standard width of axial fans for PCs, while the Heilleitrahmen 10 only one Width of 23 mm, so that the damping elements 9 project beyond the Lucasleitrahmen 10 at both ends axially by one millimeter.
- the fastening means 3 are also formed here by fastening bores, which are each arranged within an elastic damping element 9.
- each made of metal threaded sleeve 13 is cast with an internal thread in the respective elastic damping element 9 at each mounting hole 3, so that the attachment of the fan 1 in a computer case by means of metric Screws can be carried out very easily and safely.
