Description
- The invention relates to an axial fan comprising a boss and a number of blades evenly distributed and arranged to the boss, wherein the blades have an aerofoil profile. Such fans have a diameter of typically 5 meters. To guide the airflow such fans are placed in a ring which has preferably a bell shaped inlet.
- Such fans, as also disclosed in
US 4,366,387 ,WO 94/09277 GB 1,165,738 - The commonly known fans have a high number of parts and some of these parts have high manufacturing costs.
- In
figure 1 a fan according to the prior art is shown in exploded view. Such a fan comprises a boss 1 onto which a mounting plate 2 is arranged. The connection of the mounting plate 2 with the boss 1 is made by six bolts 3,washers 4 andbushings 5. Eachblade 6 having an aerofoil profile is mounted onto the mounting plate 2. In order to make this connection a cast metal block 7 is bolted to the mounting plate 2 withbolts 8 and washers 9. This cast metal block 7 comprises anelastic insert 10 to dampen vibrations. In this elastic insert 10 a hole is provided through which bolt 11 runs and with whichfork 12 is connected. Ametal tube 13 is then locked onto thefork 12 withplate 14 threadedends 15,washers 16 andnuts 17. - The
tube 13 protrudes into thehollow blade 6 and is connected thereto bybolts 18,washers 19 andnuts 20. Thehollow blade 6 is closed off byend caps - Finally to avoid an airflow through the center of the fan a
cover plate 23 can be arranged at the cast metal blocks 7. - As is clear from the prior art fan according to
figure 1 a plurality of parts is necessary to assemble a fan. On the other hand ceiling fans are known in the prior art, in which the blades are fixed to the hub by a strip. This provides for a low cost solution, but it is not possible to make any adjustments to the position and orientation of the blades in relation to the hub. Furthermore, the known ceiling fans have flat, sheet-like blades without an aerofoil profile. - It is therefore an object of the invention to provide an axial fan with less parts and consequently with reduced manufacturing costs, while maintaining the necessary adjustment options.
- This object is achieved by an axial fan according to the invention, which is characterized in that
- each blade is hollow and the strip is at least partially inserted into the blade, and that
at least one fastener runs from the surface of the blade through a corresponding opening in the strip to the opposite surface of the blade,
wherein the corresponding opening in the strip is a slot, such that the pitch of the blade is adjustable. - The strip with which the blades are arranged to the hub provide vibration damping which is achieved by the rubber in the cast metal block 7 of a device according to the prior art. Furthermore the manufacturing costs of a strip are far less than manufacturing a cast metal block 7 and a
corresponding fork 12, as is the case in a device according to the prior art. By arranging at least part of the strip into the blade, the need for theadditional tube 13 withplate 14 and corresponding mounting parts, as in a device according to the prior art, are prevented. - Furthermore by providing the strip with a slot opening the pitch of the blade is still adjustable. So due to this arrangement an axial fan with less parts and consequently with reduced manufacturing costs is achieved, while the necessary adjustment options, in particular the adjustment of the pitch of the blade, are maintained.
- In a preferred embodiment of the fan according to the invention, the strip is substantially L-shaped.
- In a further preferred embodiment the boss is substantially cylindrical and the short leg of the L-shaped strip is concave and adapted to the circumferential wall of the boss. Accordingly the L-shaped strip can be directly mounted onto the boss avoiding the need of a special mounting plate.
- In another embodiment of the axial fan according to the invention a mounting plate having a flat mounting surface is provided for each blade on the boss and the short leg of the L-shaped strip is mounted on the flat mounting surface. Although an additional mounting plate has to be provided, it avoids the need to make the short leg of the L-shaped strip concave. The necessary mounting surface is a small plate having a concave surface and an opposite flat surface. Depending on the manufacturing costs, either the embodiment with the mounting plate can be chosen or the embodiment with the short leg being concave.
- Preferably a filler element is inserted into the hollow blade. This filler element can be a very simple part, for example a cylinder, as the filler element only needs to resist the tightening forces of the fastener running through the blade and the L-shaped strip.
- In just another embodiment of the axial fan according to the invention, the filler element is substantially cylindrical and the end of the strip inserted into the hollow blade is concave. Due to the concave shape of the strip, the strip is guided along the cylindrical element and it is ensured that adjustment of the pitch of the blade will occur centered around the cylindrical filler element.
- In another embodiment of an axial fan according to the invention, the filler element comprises two semi-cylindrical parts arranged on either side of the end of the strip inserted into the hollow blade. This provides for a further simplified axial fan according to the invention, because the end of the strip inserted into the hollow blade, can stay flat, while centered adjustment of the pitch is still ensured.
- In again another embodiment of the axial fan according to the invention, the inner wall of the cavity in which the filler element is inserted is at least partially adapted to the outer surface of the filler element. This further contributes to a centered adjustment of the pitch of the blade without risk to misalignment of the blade in relation to the hub.
- Preferably, the filler element is positioned between the slot openings. This reduces the costs as no holes have to be arranged in the filler element. Furthermore the clamping is improved as a result.
- The slot openings could also be provided in the blade for adjustment of the pitch. Furthermore, the axial fan may comprise a ring shaped housing coaxially arranged to the boss. This ring shaped housing will guide the air propelled by the blades of the fan.
- These and other advantages of the invention will be elucidated in conjunction with the accompanying drawings.
-
Figure 1 is an exploded view of an axial fan according to the prior art. -
Figure 2 shows an embodiment of the axial fan according to the invention in exploded view. -
Figure 3 shows a second embodiment of the axial fan according to the invention. -
Figure 4 shows a third embodiment of the axial fan according to the invention. - In
figure 2 anaxial fan 30 according to the invention is shown. Thisaxial fan 30 has aboss 31 onto which theblades 32 are mounted. The L-shaped strip 33 has ashort leg 34, which is concave and directly bolted onto the cylindrical outer surface of theboss 31 withbolts 35 andwashers 36. Thelong leg 37 of the L-shaped strip 33 is partially bent and provided withslot openings 38. This bent part of thelong leg 37 is inserted into thehollow blade 32. It is also possible to mount the long leg of the L-shaped strip on the outside of the blade. Afiller element 47 is also inserted into theblade 32, after whichbolts 39 are inserted attaching the L-shaped strip 33, thefiller element 47 and theblade 32 to each other. Thebolts 39 are tightened bynuts 40 andwashers 41. - The
hollow blade 32 is closed off byend caps - Finally a
closing plate 44 can be attached to theboss 31 bybolts 45 andwashers 46. This closingplate 44 prevents an air flow through the center of the axial fan. - When comparing the embodiment of
figure 2 with the prior art embodiment offigure 1 it is directly clear that the invention provides a more simple embodiment, reducing the manufacturing costs. Also the embodiment according to the invention does not use parts, which are difficult to manufacture, such as cast, forged or machined metal blocks. -
Figure 3 shows a second embodiment of aaxial fan 50 according to the invention. Thisaxial fan 50 has ahub 51 andblades 52. Theseblades 52 are arranged to thehub 51 by astrip 53. One end of theflat strip 53 is bolted to thehub 51 bybolts 54. Theother end 55 of thestrip 53 is concave and provided withslot openings 56. Thisend 55 is inserted into thehollow blade 52 together with afiller element 57. Theend 55 andfiller element 57 are mounted in thehollow blade 52 bybolts 58. - The
slot openings 56 enables the pitch of theblade 52 to be adjusted. Theblade 52 together with thefiller element 57 can rotate relative to thestrip 53 due to theslot openings 56. In order to assist its rotation, the upper surface of thefiller element 57 is partially cylindrical and theinner wall 59 of the cavity in theblade 52 is provided with a concave cylindrical surface. -
Figure 4 shows part of a third embodiment of an axial fan according to the invention. In this embodiment ahollow blade 60 is arranged to a hub (not shown), by aflat strip 61. On either side of the flat strip 61 a semicylindrical filler part flat strip 61 with the two semicylindrical filler parts hollow blade 60 such that thefiller part 62 is in contact with theinner wall 64 and thefiller part 63 is in contact with the concaveinner wall 65. - In the
strip 61 twoslot openings 66 are arranged through whichbolts 67 extend and with which the blade is attached to thestrip 61. Together withwashers 68 andnuts 69 thehollow blade 60 can be attached to thestrip 61 in a desired pitch angle.
