The fan fan frame includes a shell: open; the body has a through hole, and through The holes in the two wheels of the housing are “into the housing, and the air outlets are in the middle.”, when the motor base is located at the air outlet or into the end of the different plane bottom and the air outlet or the air inlet. The fan frame further comprises a plurality of ribs, which are arranged on the bottom of the shell to the bottom of the base = 3 to the base. Each rib has a self-extension: the width or the thickness thereof is different. The housing has two inflows at the air inlet or outlet. The air outlet can increase the airflow or: or ==: the side is radially slopable to adjust the airflow and flow; and ^_! This fan system can be applied to a heat source, the second side of the through hole, § When the light emitted by the light source enters the through hole, the circumferential line exits the through hole. The outer edge of the impeller and the through hole surface, the curved surface includes one or more tapered and divergent '* mothers One blade and the other adjacent blade are on the axis of the through hole and the second stack. Shape, circle, ellipse = 夂 = motor base is - the wind contained in the system frame containing the fan assembly, the system is a power supply, a feeder or a computer. Or, 1273879 horse is - system housing The side wall 'is, for example, a fan cover. The above and other objects, features, and advantages of the present invention are more readily understood. The following is a detailed description of a preferred embodiment as follows: [Embodiment] The first 2A: 2 and C diagrams of the wind household are shown in the first embodiment of the preferred embodiment of the present invention. Please refer to FIG. 2A 'the fan 20 of the present invention, which is more than 21 Λ' and: The fan includes a fan fan frame 21 and an impeller 24. The fan 2 is "the housing 2 having a through-hole 27 is generally shaped, elliptical or diamond-shaped" and the housing 21 includes a motor base to recover the gold: ==3 The wheel 24 includes a hub 25 and a blade (μ_) 26, and the blade 26 is respectively connected to the outer edge of the hub 25, and the inside of the valley 25 is a motor body:). The impeller 24 and the motor base Both the 22 and the motor are housed in the casing Π 24 and are located on the motor base 22, and are rotated by the motor drive ^ ^ 茱 wheel 24. The rib 23 is provided Between the circumference of the through hole 27: 1 and the motor base 22' is used to support the motor base & the through hole 27 forms an air outlet 211 and an air inlet 212 at both ends of the housing 21, and the end of the ^ port T The ends of the air inlet 212 have a first imaginary plane 1 and a second imaginary plane 222. The invention has the disadvantage that the bottom surface of the conventional motor base 22 is flush with the fan frame, and the motor base 22 is lifted to the housing. In the case of 21, the depth of the formed air is provided to provide a steady flow of the fan. As shown in FIG. 2A, the motor base 22 is preferably located at the air outlet 211, and the motor base & = surface and the end of the air outlet 211 (ie the first imaginary plane 2 (1) is located in the 5 plane. Alternatively, the motor base 22 may be disposed at the air inlet 212, and 1273879 may have the bottom surface of the motor base 22 and the end of the air inlet 212 (surface 222) on different planes. After the phantom lifts the motor base 22 into the casing 21, the top surface of the ^ 25 that was originally placed on the 222 seat will protrude from the second imaginary plane as shown in the second diagram of Figure 2B. Will not affect the operation and efficacy of the fan 1 (). Alternatively, when it is considered that the fan 2 is to be applied to the volume of the _-fan 20 to be matched with the components of the system and the system, the volume of the hub 25 can be adjusted correspondingly. Hundreds and younger ones have a face 222 (as in Figure 2C), so that the top of the protruding trough does not affect the rest of the components. Referring to Figure 3A, the description is based on a preferred schematic diagram of two types of fans in accordance with the present invention. In addition to the depth of the motor base 叮nkf(4) 31 to form a volley, it is preferable that the same portion is close to the air outlet 311 or the air inlet flare 39 in the housing 31 to increase the airflow or outflow. Area, advance: Fan 2's wind and wind volume, and when the expansion portion 39 is set at the air outlet = 2, the effect of deceleration and rectification is achieved. The flared portion 39 can be a lead angle, a bevel angle, a lead angle or a large R angle, and the rib 33 is extended from the motor base 32 to support the motor base 32. The outer portion is connected to the rib 33. The other parts of the casing outside the expanded portion 39 are referred to in Fig. 3A and Fig. 3B, and Fig. 3B is a schematic view showing the fan at the end. As shown in Fig.®, when the fan 30 is applied to a heat-generating system end 3, the bottom surface of 32 and the bottom surface of the casing 31 have a depth of _ volley, and not only 1273879 I 虱 out of the wind space, thereby achieving an increase in fan air volume. The purpose, plus the addition of =P 39, to achieve the effect of deceleration and rectification, can improve the taste caused by the flow field disorder. In addition, because the motor base & on the bottom surface of the housing 31 can reduce the motor itself And the vibration caused by the impeller feed is transferred to the 3 horn 4 or the system end 3 through the motor splicing 32 and the rib 33, etc., thereby reducing the noise problem of the fan 30 being loaded into the system end, and the component may be protected. This shock and damage to the bottom of the horse I 32 can be seen as a system frame containing the fan assembly or go to the ' ι 统 3 3 3 - power supply, server or computer. For the cover seedlings? f up to the base 3 2 series The side wall of a system housing is, for example, a fan guard. The invention is not limited thereto. For example, the design of the 32 and the expansion portion 39 can be added. It is used by itself. Please refer to the figure: Figure: Figure = Example 49, A plurality of ribs ^ 4q / feathers of the housing 41 includes a flared portion 43 is connected to two columns Jealous flared portion 49 and the motor base 42 of the discharge

The slope of the line decreases gradually, or the slope of the curve decreases gradually. Alternatively, the width of each month = 43 connected to the motor base 42 is greater than the width of the rib 43 = body 41. Further, from the motor base 42, the width of each rib 43 changes in a decreasing manner. = 'can be 'the slope of the line gradually decreases' or the curve of the car 9 gradually decreases. Or, the width of the rib 43 is the largest at the two ends close to the motor bottom 4*2 and the housing 41, and the middle portion of the rib 43 is the width of the most strip 43 to the motor base 42 and the housing. As the blade 46 rotates, the closer to the outer edge of the blade 46, the fluid, that is, the flow rate of fluid near the housing 41 will be greater than the flow rate at the motor base 42 of the body t. Since the width of each rib is not the same, the width of the ribs is not the same. This two: U ribs 43 are close to the flow velocity of the fluid at a relatively fast flow rate near the casing 41, so that the wind resistance is reduced and the noise can be reduced. The width and thickness variation of =43 can be matched with each other. For example, for the design of the ribs 43 of different widths, the thickness of the ribs 43 can be reduced and the thickness of the ribs 43 can be appropriately increased to avoid the ribs 43 being too thin and affecting the shell. The gentleman's 槿-3 of the body 41 is connected to the motor base 42;:, for example, 'the mother rib 43 is connected to the body 41, which is smaller than each rib 43 connected to the shell, and the female rib The thick bismuth system connected to the motor base 42 is larger than the thickness of each rib 43 connected to the housing 41. Alternatively, the ribs Μ are connected to the width of the motor base 42 to be greater than the width of each of the ribs t t, and each rib 43 is connected to the thickness of the motor, less than each rib 43 is connected to The thickness of the casing 41 is 12 1273879. Two: The widening of the mouth is made, and the straightening can be a straight curve. In this way, each of the bases 4 2 to 4 i is a unequal section. The ribs 43 are worn between the lower edge of the blade and the ribs, and the distance is relatively high. The influence of the wind and the wind is greater than that of the embodiment of the present invention: a 5A to 5D diagram of the green light is a schematic diagram of the fan according to the present invention. In the fifth...the wind 1 shows the motor base 52 and the outer extension 59, and the side of the motor base 5 2 is the area where the airflow flows out or flows in, For the purpose of making the fan:::most:: control the performance of the fan, a τ / inverse & '丄 is retracted from the bottom surface, and the slope is, for example, a plane (such as Figure 5C) or a surface (such as the figure) ). The second fan is applied to a heat source "Temple, please refer to the second fan. According to the preferred embodiment of the present invention, the fifth type of fan: No: Figure. Fan of the 6th picture, In addition to the design of the motor base=I expansion portion 69, the re-engagement housing 61 has a curved surface j, that is, 'in the housing 61 t, the peripheral edge 671 of the through hole 67 has a surface, when emitted by the light source L When the light is emitted into the through hole 671, the light can be blocked from passing through the through hole 67. The curved surface may include one or more = and the divergent curved surface. The inner circumference of the circular arc-shaped inner fan frame and the arc type fan = In addition, the outer edge of the impeller 64 is parallel to the curved surface of the through hole and the curved surface of the 彖671, so that the gap between the blade 66 and the casing 61 can be effectively shielded; the fan has a function of blocking light. The outer edge of the fan blade (10) is made of: arc. It is juice, which can increase the area of the fan blade 66, improve the overall characteristics of the fan, 13 1273879 and match the change of the curved surface of the peripheral edge 671 of the through hole, and the strong sound of the bottom of the casing 61士, 末.
