The passive heat sink is made up of a plurality of fins with a large area, which absorbs the area where the thermal energy contacts the air through the fins, and further matches the fan to read the heat. Quickly take away from the surface of the fin to achieve high efficiency of heat dissipation. Whether you can be good or bad depends mainly on the amount of wind and clock generated. The wind i passes through the air volume of the wind σ, and the heat dissipation effect is used to dissipate heat. The effect is easy to 'and its air volume calculation method (wind volume = wind utttn rib through the ship light gas _ size. ^ blade inclination, spacing and length are the same V; == fan generated wind volume is the largest, phase $, 〇 The wind ^ exit ^ mouth ^ equals the air inlet pressure) wind _ ground fan speed, the wind pressure is determined by the shape of each blade of the fan blade, TP060287 M3Q0427 area and length are combined with each other, basically, when the fan The greater the wind pressure generated by the leaves, the shorter the air supply distance, and the longer the air supply distance. t '一唯' uses a fan to assist in the cooling and cooling of the fins. It is understood that the uniform field cannot be generated because the blades h arranged around the hub 12 (as shown in the figure) Although the tip ln of the 11 and the root 112 are synchronized with the hub 12, 'there is, the axial velocity of the blade tip located outside the blade 10 is necessarily greater than the axial velocity of the blade 11 at the top 112 (as shown in Fig. 2). The axial trapping of the airflow into the fan is not sufficient, and the airflow in the inner and outer circumferences of the flow field generated by the fan is not uniform. Moreover, the distance between the tip m of the blade is also larger than the lateral distance of each blade, thereby causing the crossover area to be different. Therefore, as far as the above two points are concerned, the air volume inside and outside the air field generated by the fan blade is bound to be severely uneven, so that the heat dissipation area corresponding to the fan cannot be uniformly cooled. Therefore, how to deal with the aforementioned fan blade The problem of varying air volume is a subject of research. ^ n [New content] The purpose of this creation is to provide a multi-layered fan blade structure that is radially disposed on the rim, with the same angle, spacing, and The degree and quantity of the matching blade group, and the effect of the inner and outer airflow of the airflow field of the 茱 茱 生 趋 趋 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 For the blade group with different blade inclination, spacing, length and quantity in the hub group, the wind pressure or air volume is generated by the demand of the heat dissipation area corresponding to the film = white. For the purpose of white people, the first embodiment of the present invention is Providing a multi-layered fan blade structure, which is a whole wheel and a plurality of fan blades disposed around the hub, and is characterized in that: the first group of the first blade group and the second group of blade groups are sequentially and radially Provided in the hub i η : and, between the blade group and the second blade group, there is a "fixed miscellaneous, so that the first root portion is equidistantly disposed around the hub" and the catastrophic end of the blade is fixed to the g edge The inner edge of the garment and the root of each blade of the second blade group, wherein the blade disposed on the fixed ring body has different blade inclination angle, shape, area, number of pieces and spacing of each blade group, and the blade leaves are generated. The air volume inside and outside the airflow flow field approaches the same, or Appropriate air volume is generated for a certain piece and the corresponding heat dissipation area. TP060287 6 M300427 κ. ^ In addition, a reinforcing rib can be added between the blade surfaces of the blade group to strengthen the blade strength and avoid the blade. The vibration occurs when rotating, causing deformation problems such as change of the angle of attack. In the embodiment, the wind pressure generated by the fan affects the fan blade, and the fan blade group generates a large wind pressure. The airflow passes through the fin spacing, and each blade of the fan blade group changes the set value of the shape, area and length of the blade, so that the blade has a large wind pressure to improve the heat convection effect between the fins. When the aforementioned fan blade group needs to directly and rapidly dissipate heat and cool down the heating element, the blade group of the group changes the shape, the area, the length of the blade, and the set value of the blade pitch. The wind pressure generated by the fan blade group is reduced and a large air volume is generated to enhance the exchange of air. [Embodiment] Μ m The technical means and other functions used for the above purposes are The second preferred embodiment is described below with reference to the following figures: ^ΐ=3Λ, and FIG. 3 is a perspective view of the multi-layered fan blade structure of the first embodiment of the present invention. FIG. 4 is a multi-layered embodiment of the first embodiment of the present invention. A schematic plan view of the blade structure. The first embodiment of the present invention provides a multi-layered fan blade structure, which is a package of it2〇H20 and a plurality of blades disposed around the wheel 20, wherein the fan blade is 53" On the rotating shaft of the stator (not shown), and the rotor around the inner stator of the hub 2, a magnetic field is generated through the stator to push the wheel (4) iii, and the heat body is cooled and cooled (not shown). The main feature of the present invention is that The four blades are at least divided into a first blade group 211 and a second fan tail, and the sequence is radially disposed on the hub 2 (eg, between the third to the second and the second blade group 212 is fixed-fixed)娜99二#片组211 Each pen J4 1Π & - , /, medium, first blade group 211 = piece 2110 roots are equidistantly set in the fan impeller fe fixed to the fixed ring body 2?

Since the two-blade group m and 212 rotate synchronously with the fan impeller 20, =, = (not shown). Although the rotational speeds of the fan blade groups are the same, the first blade group 212 requiring ff outer turns may have an axial velocity greater than the position of the first blade group 212 when rotating. ΐί : ϋ ϋ ϋϊ ϋϊ ϋϊ ϋϊ ϋϊ ϋϊ ϋϊ ϋϊ ϋϊ 由 由 由 由Air volume = wind speed * Product L knows that the wind area of the blade group 211 must be larger than the second blade. And 212 L is the same effect as the air volume generated by the fan blades. Therefore, the actual case is The cross-sectional area of the first-blade group 211 is larger than that of the second blade group, which can achieve the same effect of the air volume generated in the blade and the periphery (as shown in Fig. 4). (4) Please I's 5® This creation® 2 implements the three-dimensional inconsistency of the fan blade structure. A reinforcing rib is arranged between each blade. As shown in the figure, in order to solve the vibration of the blade 2 of the second blade group 212, the blade 212_ is caused to change the bow angle and the like, and the problem is that the blade rib 213 ' To strengthen the strength of each blade 2120 to maintain the angle of the blade angle of the blade. Please refer to Fig. 6, which is a perspective view of the multi-layer blade structure of the second embodiment of the present invention, except that the creation can pass through the first blade group 211. The wind area is larger than the second blade group> Ιΐίί each blade group produces the same air volume, and can also set different blade conditions for the heating element or the slab of the slab. For example: when the fins are separated from each other ^The fan of the fan must be older (four), only to check the fin distance of the ship. At this time, the blade group can further set the blade inclination angle, the length, and the blade of the first-blade group 211 shown in the figure 6) So that it produces (finor spacing, which improves the heat exchange rate between the fins; if it is necessary to cool down one of the heat sinks or when the spacing between the pieces is wide, then the blade is set to focus on generating a large amount of wind, corresponding to Blade sets can be set to smaller blade angles to achieve smaller Increase the pitch of the blades in the design 'to create a larger air volume. The advantage of 〆^ is that it overcomes the physical properties of the traditional fan blade due to the axial velocity of the tip and the root of the blade and the unevenness of the blade pitch, which is transmitted through the third leaf TP060287 0 M300427. Η f group and The two-blade group is radially disposed on the periphery of the fan-impeller hub to achieve a uniform effect of the airflow flow field, and can also be used for the heat-dissipating area requirements of the blade group, and the leaf blade amount, length or It is a different mix of spacing to enhance the wind house.
