Annex A Description 1 Replacement 98 al is nin, invention description noisy April t repair (more) original [Technical field of the invention] The present invention relates to a cooling device and system, especially for a heat dissipation Fan stator. [Prior Art] Electronic components may generate heat to dissipate the received power. This heat may damage or otherwise weaken the functionality of these components. Various cooling systems have been used for cooling power dissipating components, which may include processors, wafer sets, voltage regulator components, and other components. Some cooling systems utilize a fan to vent heated air from a substrate that includes a power dissipating component. Other cooling systems use a fan to create a flow of air that is directed to the power dissipating assembly to cool it. SUMMARY OF THE INVENTION According to some embodiments, an apparatus includes: a housing; a hub; and a plurality of streamlined bodies, each streamline having a leading edge, a trailing edge, a first end, and a second end Wherein the first end of each streamlined body is fixedly coupled to the hub, and wherein the second end of each streamlined body is fixedly coupled to the housing. [Embodiment] Figs. 1 to 4 show various views of a cooling system. In particular, Figure 1 is a representative cutaway side view of a system 1 of some embodiments, and Figure 2 is a perspective view of a modified version of the Chinese version of the Republic of China on January 3, 1997. January) Γ-,, > (.more) Original exploded view 'Figure 3 is the front (inlet) stereoscopic - bacteria -; Η _ 4 is the rear ** (mouth) stereo view. System 1 can include a system for cooling the device by directing air to the device. System 1 can be used in any suitable application, including but not cooling electronic components housed in a substrate. System 1 includes a housing 10 and a hub 20. A plurality of stator vanes 30 are coupled to the housing 10 and the hub 20. According to some embodiments, each stator blade is a streamlined body comprising a leading edge 35, a trailing edge 36, a #-end 37, and a second end 38. A first end of each of the primary linear bodies is fixedly coupled to the hub and a second end is fixedly coupled to the housing 10. The housing 10, the hub 20, and the leaves 30 may be constructed of materials suitable for their intended use, including but not limited to plastics, resins, polymers, and genus. The physical dimensions of the housing 10, the hub 20, and the leaves 30 may also vary depending on the intended use and/or the specifications to be followed by the system 1. According to an embodiment, the housing 10, the hub 20, and the vane 30 comprise a single integrated element. This unit can be manufactured by injection molding techniques. According to some embodiments, the fan 40 is coupled to the hub 20. As shown, the motor 60 can be disposed within the fan 40 and supported by the hub 20. The blade 50 of the fan 40 is rotated 60 to deliver air to the leading edge of the blade portion 30. As shown in Fig. 1, the input air of the pressure P〇 is received, and the air is accelerated by the rotary vane 50. The accelerated air exhibits a static pressure P1, which includes a tangential velocity vector, an axial velocity vector, and a radial velocity amount 'which depends at least on the design of the fan 40, the rate of rotation, and the position at which the accelerated air exits from the fan blade 50. . The leaf 30 receives the accelerated air. According to some embodiments, the leaf is limited to 30. The gold of the single horse is rotated to the plus part -6 - 1312267 唞 2A : Patent application No. 94137334 Chinese version of the manual replacement page December 22, 1997 Corrected the year ^ month; the rash (more) original 30 increases the static pressure of the air from P! to p2, a total axial velocity from the leading edge of the blade 30 to the trailing edge of the blade 30. The air exhausted from the trailing edge of the vane 30 is depicted as air 80 in FIG. At a particular fan rate, the flow and/or pressure of air 80 may be greater than that provided by fan 40 when there is no leaf portion 30. Figure 5 depicts the operating point 0 1 for a given housing 'work point Ο 2 and a system containing only the fan 40. As shown in the figure, 'Operation Point 02 has a larger flow rate and static pressure than the operation point i. System 1 can thereby cool the downstream components more efficiently than fan 40. The leading edge of the leaf portion 30 receives the accelerated air from the fan 4. In some embodiments, the leading edge of at least one of the leaves 3 界定 defines a first curve and the trailing edge of the blade defines a second curve. The examples of the first curve and the second curve are drawn by the broken line 3 1 of Fig. 2 and the broken line 3 2 of Fig. 4, respectively. These curves reduce the radial velocity vector' and increase the static pressure from the inlet to the outlet of the received air. According to some embodiments, the first curve of at least one of the leaves 3 〇 is at a given radius (eg, a first given radius 9 9 A or a second given radius 99 B ) and a trailing edge of at least one of the fan blades 5 其中It is perpendicular at this given radius. The constructive configuration of the latter can reduce the interaction between the leaves and the blades at any given point in the region in time, thereby producing less noise than other configurations. The leaf portion 3' of some embodiments as described above may comprise a streamlined body. If the accelerated air from the fan 40 hits the leading edge of the blade 3〇 at an appropriate angle of attack (angle 〇J attack), the streamlined body can generate a lift, which helps the received air. At least a portion of the tangential velocity is converted to pressure. In some embodiments, the blades conform to the aeronautical state -7- 1312267 (4) Advisory Committee (NACA) four-digit series streamline geometry 93xx, 94xx, 8 3xx, or 84xx. Examples of such geometric shapes include streamline geometry 9304, 94〇4, 8304, or 8404. According to these embodiments, the leaf portion is defined by a maximum camber surface of more than 8% of the length of the leaf portion. Figure 6 illustrates that the velocity vector of the received air is at least partially due to the curvature of the leaf portion 30 and the streamlined body. The blades 50 of the fan 4 are shown in a cross section. The blade 50 receives the air of the pressure P] and rotates to generate air of the pressure ρι. The generated air is represented by a vector diagram 90. As shown in the figure, the velocity vector V of the air. *® includes the axial component 乂. ® positive and negative 'line (or scroll) component V. ®**, and the radial component perpendicular to the page, V 〇 radial. - Then, the accelerated air hits the blade 30 and the leaf is also shown as a cross section. The air 8 排出 discharged from the trailing edge of the vane 30 shows that the static pressure P1 is increased from P2' and the axial velocity component is kept substantially equal to the axial component V〇 axial direction. However, the tangential velocity component Vi and the radial component Vi are radially smaller than the components v of the air received by the leading edge of the blade 30, respectively, and V. a direction. The angle at which the accelerated air strikes the leading edge of the blade portion 30 becomes smaller as the distance from the hub portion. Thus, more than one leaf portion 30 is "twisted" such that the vane angle varies with radius. When such a twist is used, the first end of one of the leaves 30 is not coplanar with the second end of the leaves 30. The leaf corner is measured by connecting a line (referred to as a string) of the leading and trailing edges of the blade. When the hub 15 is horizontally disposed, the line intersects a horizontal plane. -8- (5) 1312267 Leaf angle can be increased as a function of radius. In some embodiments, the leaflet angle of at least one of the leaves 30 is 55 degrees at the hub 20 and 75 degrees at the shell 10. Some embodiments may provide that the leaf angle of at least one of the leaves 30 is 43 degrees at the hub 20 and 73 degrees at the housing 10. According to some embodiments, the number of blades is N and the number of leaves 30 is not a multiple of N. This configuration configuration can increase acoustic interference and thereby reduce the operational noise of system 1 over other configurations. In a particular example, the number of leaves is equal to N+1. Some examples can also reduce noise by slowing down the rate of rotation of fan 40 for a given air flow. Figure 7 is a perspective view of a thermal module 200 using system 1 of some embodiments. The thermal module 200 also includes a housing 210, an electronics assembly 300, and a heat sink 310. The relevant portion of the housing 210 is painted transparent to enable viewing of the electronic component 300 and the heat sink 310. According to some embodiments, the thermal module 200 uses the air 80 produced by the system 1 to cool the heat sink 310. Electronic component 300 can include any thermally dissipative component including, but not limited to, integrated circuitry (e.g., microprocessors, chipsets), and power switching components. The heat sink 3 10 can comprise any material (e.g., copper, aluminum) and can include any cooling device now known or later known. As illustrated, the heat sink 310 includes a thermally conductive fin 3 15 to dissipate heat from the electronic component 3 周围 to ambient air. When compared to other systems, the increase in the axial velocity component of the air 80 relative to its tangential component reduces the rotational loss at the edge of the fins 315, resulting in more efficient cooling of the assembly 300. In addition to the 1312267 (6), at a given rate of the fan 40, the static pressure of the air leaving the module 2 Ο 0 is greater than previously available. FIG. 8 is a perspective view of a system 400 of some embodiments. System 400 can include a desktop platform. System 400 uses air 80 produced by thermal module 200 to cool a plurality of system components.

The housing 410 is shown as being transparent to enable viewing of the components of the system 400. The module 200 of FIG. 7 can be identical to the module 200 of FIG. 6, except that the system 1 extends upright below the main substrate 420. The upright extension may allow a portion of the air 80 to travel from the blade 30 through the space between the main substrate 420 and the housing 410. The various components can be assembled to the main substrate 420, including the body control hub 430, the input/output control hub 440, the add-on card 450, the 452 '454 'memory card 460, and the input/output interface 470. System 400 also includes removable media drive 480, hard drive 490, and power supply 500. Any other system components and configurations can be used in some embodiments. Air 80 from the thermal module can be used to cool one or more components of system 400. In some embodiments, air 80 may flow through the heat dissipating assembly, hubs 430, 440 assembled on one side of the drawing add-on card 450, and may be exhausted through a rear panel (not shown) of the housing 410. The increased axial flow of air 80 of system 1 relative to the tangential flow reduces the loss caused by heat sink 3, thereby providing greater air pressure to cool other components. If additional air pressure is not required, system 1 can operate at lower fan speeds and acoustic levels to deliver the same air flow that the system produces at higher fan speeds and acoustic levels. -10- 1312267 Attachment 2A: Patent Application No. Ml37334 Chinese Manual Replacement Page Republic of China 97 _ 1 Wu 3曰 Amendment Year of the Lunar New Year?
