Abstract
A fan frame comprises a frame body, motor base, at lease one flow guide set and a line device. The frame has a hole, to which fixed the motor base. The flow guide set is a fixed blade or a curve lib which is fixed between the frame and the motor base. The line device is to orientate the power line and lead it out of the frame. The line device is linked to one of the flow guide set. With the combination of the flow guide set and the line device, a flat windward side is formed, so decrease windage resistance and increase fan efficiency.
Description
Technical field
The invention relates to a kind of fan frame, particularly about a kind of fan frame of windage outlet can be reduced the time.
Background technique
Along with making rapid progress of science and technology, various electronic product is accurate day by day, yet under the but small day by day trend of size, how to accomplish good heat radiating, makes electrical assembly maintain certain specific range of temperatures and normal operation, is an important topic in fact.Radiation fan is widely used in the electronic product of various heatings, generally speaking, the impeller of radiation fan is assembled in the framework of fan frame, again this framework is arranged in the computer housing position corresponding to ventilated port, or be arranged near the heating element of desire heat radiation, relend by the running of motor driven impeller, electrical assembly heat is on every side waved be dissipated to outside the ventilated port, and then reach the purpose of heat radiation.
Please be simultaneously with reference to Figure 1A and Figure 1B, Figure 1A is the fan frame schematic representation of existing axial flow fan, and Figure 1B is the whole cut-away view of the existing axial flow fan done along A-A direction among Figure 1A.Assemblies such as bearing motor (not being illustrated among the figure) and impeller 17 in the fan frame 11 of existing axial flow fan 10.In Figure 1B, fan frame 11 is one to have the framework of perforate, and perforate two ends respectively are formed into air port 12 and exhaust outlet 13 on framework 11, and motor base 14 is arranged in the framework 11, and is positioned at exhaust outlet 13 places.Motor base 14 is in order to carrying impeller 17, and a plurality of stator blade 16 is arranged at 14 of framework 11 and motor bases, but the flow direction of air-guiding.
With the power line 15 of impeller and the group relation of establishing of framework 11, existing fan majority all power line 15 is gathered become to put in order bundle after, put along the side of stator blade 16, and utilize and on framework 11, to set up a branch of limit and be with 18, make and to gather to become put in order power line 15 behind the bundle, seen through this and restraint to limit and be with 18 and fix.Bundle is limit the setting with 18, and general all positions are near stator blade 16 connection frameworks 11 places.
Yet; because the outlet of existing axial fan 10 design is not good; regular meeting hinders air-out because of power line 15 is across exhaust outlet 13 places; the feasible smooth-going air-flow that imports from wind inlet 12 originally; when flowing through power line 15; put the non-level and smooth windward side that is produced because of power line 15 along stator blade 16 side-swaies and cause windage, make the blast of axial flow fan 10 or air quantity descend.For large-scale fan, it influences more so.
Please refer to Fig. 1 C, it is the fan frame schematic representation of another kind of existing axial flow fan.The another kind of existing practice then is to use a plurality of rectangular column ribs 19, and rib 19 is arranged at framework 11 and 14 of motor bases, in order to support motor base 14.The power line 15 that connects impeller then can be arranged at rib 19 behind, can avoid producing the phenomenon that causes windage as the non-level and smooth windward side of outlet seat 18 among Figure 1B.Yet simple rib 19 designs also can't be satisfied the characteristic requirement of user for various blast or air quantity, therefore, how to take into account under the fan duty demand, and the windage that is caused in the time of more lowering outlet is a problem to be studied in fact.
Summary of the invention

Embodiment
Please be simultaneously with reference to Fig. 2 A and Fig. 2 B, Fig. 2 A is the fan frame schematic representation according to the axial flow fan of preferred embodiment of the present invention, and Fig. 2 B is the cut-away view of the integral body of the axial flow fan done along B-B direction among Fig. 2 A.Among Fig. 2 A, comprise assemblies such as motor base 24, motor (not being illustrated among the figure) and impeller 27 in the fan frame 21 of fan 20 of the present invention, and this fan preferably is an axial flow fan, can be applicable to large-scale board, server system, on assembled fan or other electronic equipment that can generate heat, as the usefulness of heat radiation.
Please be simultaneously with reference to Fig. 2 B and Fig. 2 C, Fig. 2 C is the enlarged view of Q part among Fig. 2 B.Framework 21 derives in order to location power line 25 and with power line 25 in fan outlet mechanism 28.Wherein, fan outlet mechanism 28 combines with wherein a stator blade 26.Fan outlet mechanism 28 has a metallic channel 31, and the opening of metallic channel 31 is outside framework 21, and power line 25 is inserted in the metallic channel 31.Because metallic channel 31 is positioned at stator blade 26 times, therefore fan outlet mechanism 28 does not directly meet the flow direction to air-flow, so when the smooth-going air-flow from wind inlet 22 importings, be the smooth-going windward side of stator blade 26 of flowing through, see through the guide functions of stator blade 26, directly flow out by exhaust outlet 23.And because power line 25 is to insert in the metallic channel 31, also be positioned at stator blade 26 times, can overcome to have now and will gather to become to put in order the power line of restrainting hinders air-flow when the stator blade side is put shortcoming.
Perhaps, an end of metallic channel 31 connects motor base 24, and the other end then directly exposes to framework 21, makes that power line 25 is able to directly export to outside the framework 21 behind fan outlet mechanism 28 location.In addition, a limitation part 29 can be set preferably on metallic channel 31, for example be a clip, bundle limit band etc., comes off to prevent the power line 25 in the metallic channel 31, shown in Fig. 2 A.
Perhaps, metallic channel 31 1 ends connect motor base 24, and the other end then directly links to each other with framework 21, and also a perforate can be set on framework 21, makes that power line 25 is able to directly be exported to outside the framework 21 after passing perforate.
In addition, fan outlet mechanism 28 can also reach by alternate manner except with the metallic channel mode bearing power line, for example, the stator blade 26 of one of them is done a perforation, makes power line 25 insert in the space that perforation has, and exports to outside the framework 21.
In sum, axial flow fan in above-mentioned preferred embodiment fan frame, the width of each fluid control unit can be identical or different, so long as can not weaken the blast of former axial flow fan and air quantity characteristic all be applicable to the present invention.For example, be combined with the stator blade 26 of fan outlet mechanism 28, its wider width in other not in conjunction with the stator blade 26 of fan outlet mechanism 28.Disclosed fan frame will go out wire casing and combine with the fluid control unit, producing a smooth-going windward side, and then lower windage, the usefulness of promoting fan.
Though the present invention discloses as above with a preferred embodiment; yet it is not in order to limit the present invention; any person skilled in the art person without departing from the spirit and scope of the present invention; when the change that can make various equivalences or replacement, so protection scope of the present invention is when looking accompanying being as the criterion that the application's claim scope defined.
