Description
Technical field
The present invention is about a kind of radiation fan, especially a kind ofly prevents from pointing or foreign matter enters the radiation fan of fan frame inside.
Background technique
Please refer to shown in Figure 1, existing radiation fan roughly comprise one the fan frame 81, a driver element 82 and an impeller 83.This fan frame 81 is provided with a wind inlet 811 and an exhaust outlet 812; This driver element 82 is arranged at this fan frame 81 inside; This impeller 83 is rotatably in conjunction with this driver element 82; Whereby, this driver element 82 can drive this impeller 83 rotations, make this impeller 83 introduce the air-flow in extraneous space from this wind inlet 811, and can be disposed to the heat source position that produces when an electronic product (not illustrating) is worked via this exhaust outlet 812 in this air flow collection, the temperature when working to reduce this electronic product.
Yet existing radiation fan is being installed in various electronic products, and when driving this impeller 83 High Rotation Speed by this driver element 82, because wind inlet 811 and the exhaust outlet 812 of this fan frame 81 there is no any structural design with block function; Therefore, when user's finger stretches to this fan frame 81 inside via this wind inlet 811 and exhaust outlet 812 accidentally, will easily cause unexpected injury; Perhaps, if when foreign matter enters to this fan frame 81 inside via this wind inlet 811 and exhaust outlet 812, also may cause these impeller 83 damages under the High Rotation Speed state.
By improving the issuable relevant issues of above-mentioned existing radiation fan, on the market also research and development another kind of have can prevent from pointing or foreign matter enters the radiation fan of fan frame inside.Please refer to shown in Figure 2, for TaiWan, China is announced " being convenient to the cooling fan structure of unloading, replacing " Patent Case No. 516798; The existing radiation fan of this another kind consists predominantly of a pedestal 91 and several fan bases 92.One side surface of this pedestal 91 is provided with hook portion 911; These several fan bases 92 have respectively can be for arranging the holding area 921 of several fans 93, and be provided with several through holes 922 that are communicated with this holding area 921, and respectively this through hole 922 all has several ribs 923; In addition, these several fan bases 92 are provided with several by press button 924, when these several fan bases 92 mutually combine with this pedestal 91, these several fix with these several hook portion 911 mutual buckles respectively by press button 924.
The existing radiation fan of above-mentioned another kind can be installed in several fans 93 between this pedestal 91 and this several fan bases 92 when reality is used; Block effect by several ribs 923 of the protection of this pedestal 91 and these several fan bases 92; enter to this fan 93 via the through hole 922 of these several fan bases 92 when inner with the finger that effectively prevents the user or foreign matter, the possibility that occurs to reduce unexpected injury.
Yet, to consider based on safety in utilization, the above-mentioned further limit of several ribs 923 spacing each other that is formed at these through hole 922 inboards so can avoid user's finger or foreign matter to enter to fan 93 inside via this through hole 922.But respectively this fan 93 is in the process that reality is used, still must derive or import air-flow by the through hole 922 of these several fan bases 92, at this moment, each rib 923 of these through hole 922 inboards easily hinders the circulation of air-flow on the contrary, cause air output or the air output of the air-flow that this fan 93 drives relatively to reduce, and then affect the radiating effect of this fan 93.In addition, this existing radiation fan mainly is installed in this fan 93 between this pedestal 91 and several fan bases 92, not only use in assembling and cause inconvenience, and overall structure is also too complicated, therefore still have necessity of being improved.
In addition, please refer to shown in Figure 3, for China applies for " assembled fan and fan frame structure thereof " patent of invention 01131057.X number.Should comprise a fan 71 and a fan frame 72 by existing assembled fan 7, these fan frame 72 inboard several stator blades 721 of configuration, when this fan 71 running, several stator blades 721 of this fan frame 72 can promote air quantity and the blast of this fan 71.
Yet, several stator blades 721 of the fan frame 72 of above-mentioned existing fan 7 only can be in order to air quantity and the fan that promotes fan 71, when this fan frame 72 is installed on the exhaust outlet of this fan 71, because these several stator blades 721 only can be in order to air-guiding by between these several stator blades 721, these several stator blades 721 do not form safety clearance each other, therefore, user's finger or foreign matter still may enter to fan 71 inside via formed gap between these these several stator blades 721, equally easily cause unexpected injury or cause this fan 71 under the High Rotation Speed state to be damaged.
Summary of the invention
