Description of Invention (彳) In the example, the fan according to the present invention has a special feature: during the operation, the rotor is magnetically suspended. A further increase in efficiency can be obtained by an embodiment, in which the blade has a shape with a maximum CL / CD at a minimum (CD) 0, and its shape impedance CL is zero. A light but very mechanically strong embodiment has the following special characteristics: the fan blade system is connected to the wheel valley and the ring under bias. Another variant embodiment with a very light weight rotor has the following special features: each fan blade includes a skin part made of a metal with a maximum thickness of 1 mm. A particular embodiment has the following special features: each fan blade system includes a skin portion, the skin portion is composed of a plastic layer, the plastic layer is selectively made of a tensile The fibers are reinforced. The above two embodiments can be characterized by K: the epidermis has a thickness of 0.001-1.03 times the average chord of a blade. In particular, when the bias is applied to the latter variation embodiment, it is possible to use a very thin skin part. Then, the fan may have a special feature such as the following: the epidermis has a thickness of (0.2 ± 0.1) mm. Different suitable materials are available.

Invention description (f) The actual curing example of the Department is considered. In order to increase the resistance to deformation caused by shaking or the like, the fan may have the following characteristics: the cavity surrounded by the skin portion may be filled with a filler. The latter embodiment can be manufactured in a simple manner. This Ben embodiment has a special feature under M: the filler is first molded in a cavity of the mold, and then, the skin portion is arranged to surround the filler. One further improvement in efficiency can be achieved by an embodiment: the number of blades is more than four. For example, the number of the fan blades may be eight or more. When an aerodynamically optimal design is used, the efficiency can be very high compared to conventional fans, and besides, the allowable range of the rotational speed can be greatly expanded. An example of the average thickness of the blade may be 15% of the chord. In conventional designs, this thickness is 2 to 3% of the chord. With such a design, the drag coefficient CD decreases, while the lift coefficient CL can be increased (eg, from 0.8 to 1.6). The efficiency of the fan is related to the CL / CD quotient. The efficiency of the fan can be increased to 9% by these steps. In conventional designs, this efficiency has a maximum size of 50%. The reduction of the CD can also reduce the occurrence of dry noise. One of the advantages of using a larger number of blades is that the rotational speed of the use can be reduced and the generation of noise can be relatively reduced.
