Creation description (1) [Technical field to which the new type belongs is related to a kind of service, especially the centrifugal cooling fan structure of its fan blade part [previous technology] j new structure space type Designer. According to the centrifugal fan, the effect of the gas flowing in a predetermined direction is the effect of the Z force on the gas and the heat dissipation function; the main part of the air flow must be used as a rotation or by the radial direction to pass through the blades. Leaving = direction is the return flow along the axis of the rotation axis (Circulatl0 = wind two in this process, there are two main sections, the air flow from the axial direction) the second will rise, the fan performance 'its-is in The axial fan inlet cover side forms an axial return, and the two t's are easy to lean against the radial section on the upper end of the fan blade, as the two leaves are shown in Figure 5; the second is the inertia effect caused by it: 2 gradually expanding angle I 'and rotation are shown; for the axial surface to return to t to the surface; as shown in "Figure“, the easier the axial surface return: the smaller the space from the axial to the radial direction, the smaller the space, Short information to avoid ... In this case, #backflow to the surface is almost more difficult than a narrow flow channel ;: ==, wide flow channel will have a backflow phenomenon; according to the above principle, i increase the blade to form a narrower flow The problem points of the road are stated: ㊉See the centrifugal fan structure In the conventional scattered orbit wind attachment as disclosed in National Patent Bulletin No. 536 1 30-) ', its characteristics include short blades 33, and the problem with being fixed to the short conventional structure lies in the following: M254887 Creation instructions (2) ____, the second stream is almost vertical, so it will cut the airflow =, the connecting ring 34 is placed under the fan blades, and there is only a fixed short fruit; it is located just at the turning point of the airflow introduction. For the airflow: = Can ': Degree of interference' makes the flow channel more than the inlet cover, the nature: the phenomenon of phase backflow, more made by the connection ring 34 ^ 1 produced by the national patent publication 536 1 3〇 The other one disclosed by No. —, = (as shown in Annex II), is mainly characterized by the combination of acupuncture points, the fan mouth stands up, and its connecting ring 2 has a set of upper and middle feathers (please compare) The problem with the kappa structure shown in the fifth, fourth, and third figures of the second appendix is that the axial fan blade I ': = knows the pressure of the air inlet to increase the wind repeat, but at noon :: Force: In the fan, the strong axial and vortex spatial disturbance caused by the outline leaf " The inlet flow field of the centrifugal fan blades has the following effects :: Second, the heart fan blades are inferior. It is farther away than earlier, as shown in Figures 4 and 5 of another conventional cooling fan structure, i, which lies in the The blades of the fan include a long, spaced arrangement: known. = The connecting ring 53 is located under the fan blades ^ This section is connected; the problem of rf has the same points as the aforementioned attachment 1, that is, the i leaf ΓΓ plays the function of short blade 52, and it causes a considerable degree of interference on airflow: confidentiality, so that in addition to the damage of the air inlet: the backflow (A) phenomenon generated by the flow path, more is caused by the connection ring 53 Therefore, in view of the problems of the above-mentioned conventional centrifugal cooling fans, how to integrate their advantages and develop a new type of junction with more ideal practicability.
