Description of the Invention: [Technical Field] The present invention relates to a structure type of a centrifugal portion, an innovative designer-type cooling fan, particularly a blade thereof. [Prior Art] A centrifugal cooling fan and a centrifugal heat sink The fan blade "β, the difference point" is based on the introduction, and then the centrifugation of the blade to the outside air is set by the direction of the person's rear wind ==, the airflow "the wind mouth guides the plastic gas production guide, the second steady state Produces a loud voice, and at the same time...-the smoothness of the guide reduces the heat dissipation. There is a clock here. At present, although there is a windshield in the air inlet of the industry fan, there is a structure of the wind-blocking ring. The centrifugal heat-dissipating wind is used in practical applications, and it is a sigh. However, this kind of conventional structure R is willing to use it, although the choke ring can reflow effect, but the formation of the choke ring "to a certain degree of reduced air volume, so there is a = structure but also relatively affects the benefits of 1 ^ Dingsheng The shortcomings. The point is: What is the existence of the structure of the cooling fan? It is necessary for Jingjie to think about it again: the new structure of the standard and the side of the party, and the establishment of the relevant products for the development of the Si-year. After the design and careful evaluation, 5 200939938 - the invention is finally practical. SUMMARY OF THE INVENTION A main object of the present invention is to provide a blade and a crucible structure of a centrifugal cooling fan, and the problem to be solved is to solve the conventional centrifugal heat dissipation: the design of the reflow prevention structure is still There is a large airflow frictional resistance and noise, and the big problem is to think about a breakthrough; the blade is in a plurality of spaced intervals: around the axial housing of the cooling fan, the blade is a sheet-like body and defines a shape into a leaf surface, The top side edge, the bottom side edge and a wing tip portion; the technical feature of the problem solved by the invention is mainly to make the partial or the top side edge of the blade or/and the bottom side edge and add a laterally protruding flange With this innovative and unique design, the present invention can achieve the following advantages in comparison with the prior art:

The flange portion is laterally convex and can form a reinforcing force effect on the blade as a structure of the rib, so as to improve the structural strength of the blade. [Embodiment] Please refer to Figures 1, 2 and 3, A preferred embodiment of the blade structure of the centrifugal heat-dissipating wind feather is invented, but the embodiments are for illustrative purposes only. The patent application is not limited by this structure; the blade 10 is in the plural number 6 200939938. Around the hub housing 2i of the fan 20, the blade 1 is a sheet-like body defined to define a blade surface 11, a top side 12, a bottom side 13 and a wing tip portion 14, and the partial or total The top side 12 or/and the bottom side 13 of the blade 1 is provided with a laterally protruding flange portion 15, and the position of each of the flange portions 15 corresponds to the housing 22 of the heat dissipation fan 20, corresponding to The air inlet 23 of the casing 22. Wherein, the flange portion 15 may be formed by the top and bottom side edges 12, 13 gradually rising toward the wing tip portion and widening the angle of the edge piece (see Fig. 2 for details). In this case, the flange portion may have a plurality of specific types, and the flange portion 15 as shown in FIG. 3(a) is first disposed on the top side 12 of the blade 1 toward one side. a pattern of protrusions, wherein the flange portion 15 and the leaf surface 11 of the blade 1〇 may be formed with a reinforcing slope 16 (as shown in FIG. 3(b); and FIG. 3(C) The flange portion 15 is shown as being disposed on the top side 12 of the blade 10 and projecting toward both sides to form a cross-sectional shape; and the flange portion as shown in FIG. 3(d) 15, which is disposed on the top of the blade 1 and the bottom side 12, 13 convex toward the same side, forming a flange as shown in Fig. 3; The portion 15 is formed on the blade-shaped top and the bottom side edges 12 and 13 so as to protrude toward the different sides to form a redundant sectional shape. Wherein, as shown in FIG. 4, the blade surface 1 of the blade 1 is spaced apart from the flange portion 15 and a reinforcing rib 17 developed along the direction in which the blade 1 is extended can be added, thereby enabling further improvement. - Step to strengthen the structural strength of the blade. Here, as shown in Fig. 5, the heat dissipating fan 2 is connected to the wing tip portion 14 of all the blades and can be coupled by a ring rib. ^ 7 200939938 As shown in Fig. 6, the blade arrangement of the cooling fan 20 may be such that the bottom side 13 of all the blades 10 has an annular bottom plate 19 connected thereto. With the above structural design, the structure of the heat dissipating fan 2 of the present invention is cored and rushed by the top side 12 or/and the bottom side 13 of the blade 10. Further, the flange portion 15 which is laterally protruded is characterized in that the flow guiding area of the blade 10 can be expanded by the lateral convex configuration of the flange portion 15 when the blade 1 is operated to generate a flow guiding action. Therefore, the heat dissipation airflow can be more strongly pulled out of the outside by the 〇V, so that the wind pressure and the air volume of the cooling fan 2G can further increase the advantages of the invention: 1. Mainly by the unique design of the blade, the raft can enter and go The width does not increase the sound, and due to the wind of the convex heat-dissipating fan to the cooling fan effect 2, the flange portion lateral convex structure reinforcing gain effect 3, by the flange portion and the blade design, Step-by-step rugged. The top and bottom sides are provided with an innovative one-step expansion of the flange to expand the flow area of the blade, but the blade is added, so the overall volume of the cooling fan is not affected by the shadow edge portion, which can enlarge the flow area of the blade, so that the pressure and the air volume can be increased. Further increase, and then the advantages of Danone. Stretching and forming the blade like a rib can achieve the advantage of increasing the strength of the blade. The structure of the reinforcing bevel is formed between the leaf faces to enhance the structural strength of the flange portion, so that the above embodiments are disclosed to explain the present invention in detail, and the text 200939938 is described by specific terms, and cannot be limited thereto.
