Abstract
A fan frame of an axial-flow type thermal fan comprises a frame body, a support seat and a plurality of stationary blades, wherein the frame body is provided with an air inlet and an air outlet, the support seat is arranged on the inner side of the frame body, the stationary blades are arranged between the frame body and the support seat, in addition, the frame body defines an axial base level ofthe air inlet facing the air outlet, each stationary blade which is perpendicularly arranged on a horizontal base level of the axial base level is respectively provided with a radial cross-section, atleast two stationary blades have different radial cross-sections, therefore, when in the process of airflow passing through each stationary blade, noises with the same vibration frequency cannot be easily produced.
Description
Technical field
The utility model is about a kind of fan frame structure, especially a kind of fan frame with axial-flow type radiator fan of stator blade design.
Background technique
The impeller of at present common on the market radiation fan all has several blades, and respectively this blade has an angle each other respectively, and respectively the angle of this angle is identical.Therefore, when each vane drive air-flow of this impeller carries out in the process of thermolysis, then be easy to generate the noise (Tone) of identical vibration frequency, and further form the noise of single-frequency via the transmission of air.
For this reason, as No. 97132907 " heat radiating fan wheel " patent of invention, be about to the angle that is designed to have different amount between each blade of impeller, make this impeller carry out in the process of thermolysis at the extraneous air-flow of driving, respectively this blade is difficult for producing the noise (Tone) of identical vibration frequency each other, so really can further reduce the intensity of the single-frequency noise that is produced.Yet, should existing impeller also because the angle angle difference of this blade respectively, cause the complexity of the follow-up balance correction operation of this impeller to improve relatively, and must spend angle correct or transient equiliblium test that more human resources are carried out each blade of this impeller, so the economic benefit of not meeting.In addition, again with the fan frame of general common existing axial-flow type radiator fan, usually the design that has stator blade, but at present not capable yet field technique personnel thinking makes each blade be difficult for producing the noise (Tone) of identical vibration frequency each other how by the design of stator blade.
Announce " fan forced inducer device " novel patent No. 488497 as TaiWan, China, disclose first kind of fan frame structure with stator blade.Please refer to shown in Figure 1, this fan frame 90 has a housing 91, these housing 91 inboards have a placing part 92, this placing part 92 can be in conjunction with a flabellum 93, and this placing part 92 connects the flow guide device of being made up of several stator blades 941 94, each stator blade 941 is distributed in around this placing part 92 with radial, in order to derive the air-flow that these flabellum 93 rotations are produced, so that strengthen the blast of this air-flow.
Yet, because the shape and the size of flow guide device 94 formed each stator blade 941 of existing fan frame 90 are identical, also promptly these several stator blades 941 distance each other is also identical, therefore, when driving air communication, crosses in the process of this stator blade 941 respectively this flabellum 93, though can add the blast of air blast by this stator blade 941 respectively, but easily produce the noise of identical vibration frequency (Tone) also because of the design of this stator blade 941 respectively, and can further form the noise of single-frequency via the transmission of air, so still have necessity of being improved.
As I276743 number " the fan frame and the fan of tool flow-guiding stator blade " patent of invention of TaiWan, China certificate, disclose second kind of fan frame structure with stator blade again.This fan frame also has several stator blades of equidistant arrangement, and between per two stator blades, the inner edge from this fan frame respectively extends a wing conducting element again; By the collocation between each wing conducting element and each stator blade, reducing the generation of turbulent flow, and then reduce air communication and cross the issuable noise of each stator blade.Yet, though should utilize each wing conducting element to reach the function that reduces noise by existing fan frame, but must form several wing conducting elements in addition at this inner edge of fanning frame also, thus cause this fan frame to make being difficult in the moulding, and cause the increase of the manufacture cost of this fan frame relatively.Moreover the shape and the size of each stator blade of this second kind existing fan frame are also identical, so when air communication is crossed respectively this stator blade, still be easy to generate the noise (Tone) of identical vibration frequency, and further form the noise of single-frequency.
As M287387 number " the fan frame and the fan of tool flow-guiding stator blade " novel patent of TaiWan, China certificate, disclose the fan frame structure that the third has stator blade again.This fan frame also has several stator blades of equidistant arrangement, and wherein each stator blade surface has at least one conducting element that along the circumferential direction extends; By the rectification effect of each conducting element, still can reduce air communication and cross the issuable noise of each stator blade.Yet this existing fan frame is necessary in addition in each this conducting element of stator blade surface forming, therefore, can cause this fan frame to make being difficult for and its manufacture cost of increase in moulding equally.Moreover the shape and the size of each stator blade of this third existing fan frame are also identical, so still have the problems such as noise of easy formation single-frequency.
In sum, with the identical existing impeller of the angle angle of each blade, in driving the process that air-flow carries out thermolysis, be easy to generate the noise (Tone) of identical vibration frequency; Again with the different existing impeller of the angle angle of each blade, though can solve the problem of the noise (Tone) that produces identical vibration frequency, but further cause the angle correct or the transient equiliblium test of each blade difficult more, even because this impeller is difficult for finishing the balance correction operation, so may cause the product quality of this impeller not good, result in the phenomenon that double swerve takes place in the actual rotary course easily, under long-time running, may cause the associated components of this impeller to damage.Moreover, because existing impeller all is installed in the fan frame with the operation of dispelling the heat, but the shape and the size of each stator blade of fan frame structure that has stator blade at present is all identical, how also not capable field technique personnel thinking will improve the fan frame structure with stator blade, to solve the noise shortcomings such as (Tone) that is easy to generate identical vibration frequency in the impeller operation, generally speaking, truly have necessity of being improved.
The model utility content
The utility model provides a kind of fan frame of axial-flow type radiator fan, by shape or several different stator blade designs of size, to be easy to generate the problem of the noise (Tone) of identical vibration frequency in effective reduction impeller operation, is main goal of the invention.
