Abstract
The invention discloses a fan frame for an axial flow type radiating fan, which comprises a frame, a bearing seat and a plurality of fixed blades. An air inlet and an air outlet are formed on the frame; the bearing seat is positioned at the air outlet position of the frame; one end of each fixed blade is connected with the bearing seat; and the other end of each fixed blade is connected with an inner peripheral wall of the frame. In addition, an inclined angle is formed between two adjacent fixed blade; each inclined angle has an angle value; and a plurality of inclined angles respectively formed by the plurality of fixed blades have two or more angle values, so each fixed blade can be arranged at different intervals. Therefore, when the airflow passes through each fixed blade, noise with the same vibration frequency is hardly generated.
Description
Technical field
The present invention is about a kind of fan frame structure, especially a kind of fan frame with the axial-flow type radiator fan of stator blade design.
Background technique
The impeller of common radiation fan all has several blades on the market at present, and respectively this blade has respectively an angle each other, and respectively the angle of this angle is identical.Therefore, at each vane drive air-flow of this impeller, carry out in the process of thermolysis, easily produce the noise (Tone) of identical vibration frequency, and via the transmission of air, further form the noise of single-frequency.
For this reason, as TaiWan, China application case number No. 97132907 < < heat radiating fan wheel > > patent of invention, soon between each blade of impeller, be designed to have the angle of different amount, make this impeller drive extraneous air-flow to carry out in the process of thermolysis, respectively this blade is difficult for producing the noise (Tone) of identical vibration frequency each other, therefore really can further reduce the intensity of produced single-frequency noise.Yet, this existing impeller is also because the angle angle of this blade is respectively different, cause the complexity of the follow-up balance correction operation of this impeller relatively to improve, and must spend angle correct or transient equiliblium test that more human resources are carried out each blade of this impeller, therefore the economic benefit of not meeting.In addition, again with the fan frame of general common existing axial-flow type radiator fan, it has the design of stator blade conventionally, but does not have yet at present relevant practitioner's thinking how by the design of stator blade, makes each blade be difficult for each other the noise (Tone) of the identical vibration frequency of generation.
As No. 488497 < < fan forced inducer device > > new patent of TaiWan, China bulletin, disclose a kind of fan frame structure with stator blade.Please refer to shown in Fig. 1, this fan frame 90 has a housing 91, these housing 91 inner sides 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 94 being comprised of several stator blades 941, each stator blade 941 is with radial this placing part 92 surroundings that are distributed in, and the air-flow producing in order to derive these flabellum 93 rotations, to strengthen the blast of this air-flow.
Yet, because formed each stator blade 941 of flow guide device 94 of existing fan frame 90 is all equidistant spread configuration, also the formed several angles of these several stator blades 941 angle value is each other all identical, therefore, when this flabellum 93 drives in the process of air-flows by this stator blade 941 respectively, though can add the blast of air blast, but easily because of the design of equidistant each stator blade of arranging, produce also the noise (Tone) of identical vibration frequency, and can further form via the transmission of air the noise of single-frequency, therefore still have necessity of being improved.
Again, as fan frame and the fan > > patent of invention of TaiWan, China certificate I276743 < < tool flow-guiding stator blade.This fan frame also has several stator blades of equidistant arrangement, and between every two stator blades, respectively extend a wing conducting element from the inner edge of this fan frame; By the collocation between each wing conducting element and each stator blade, to reduce turbulent generation, and then reduce air-flow by the issuable noise of each stator blade.Yet, though this existing fan frame utilizes each wing conducting element to reach the function that reduces noise, but must fan at this several wing conducting elements of another formation of inner edge of frame also, thus cause this fan frame to make being difficult in moulding, and relatively cause the increase of the manufacture cost of this fan frame.
Again, as fan frame and the fan > > new patent of TaiWan, China certificate M287387 < < tool flow-guiding stator blade, this fan frame also has several stator blades of equidistant arrangement, and wherein each stator blade surface has at least one conducting element along the circumferential direction extending; By the rectification effect of each conducting element, still can reduce air-flow by the issuable noise of each stator blade.Yet this existing fan frame must be separately in each this conducting element of stator blade surface forming, therefore, can cause equally this fan frame to make being difficult for and increasing its manufacture cost in moulding.
In sum, with the identical existing impeller of the angle angle of each blade, in driving air-flow to carry out easily producing the noise (Tone) of identical vibration frequency in the process of thermolysis; 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 angle correct or the transient equiliblium test of each blade more difficult, even because this impeller has been difficult for balance correction operation, therefore may cause the product quality of this impeller not good, cause, in actual rotary course, the phenomenon of double swerve easily occurring, under long time running, may cause the associated components of this impeller to damage.Moreover, because existing impeller is all installed in fan frame with the operation of dispelling the heat, but each stator blade at present with the fan frame structure of stator blade is all the design of equidistant arrangement, there is not relevant practitioner's thinking will how to improve the fan frame structure with stator blade yet, to solve in impeller operation process, easily produce the shortcomings such as noise (Tone) of identical vibration frequency, generally speaking, truly have in addition improved necessity.
Summary of the invention
The invention provides a kind of fan frame of axial-flow type radiator fan, the several stator blades that arrange by non-same arranged with interval, effectively to reduce the problem that easily produces the noise (Tone) of identical vibration frequency in impeller operation process, are main goal of the invention.
For reaching aforementioned goal of the invention, the technological means that the present invention uses provides a kind of fan frame of axial-flow type radiator fan, comprise a framework, a load bearing seat and several stator blade, this framework has a wind inlet and an exhaust outlet, this load bearing seat supplies an impeller combination and is positioned at the air outlet position of this framework, respectively one end of this stator blade connects this load bearing seat, and the other end connects the inner side perisporium of this framework; In addition, respectively this stator blade has respectively an angle each other, and respectively this angle has respectively an angle value, and several angles that wherein these several stator blades form respectively have two or more angle values.
The beneficial effect that can reach by above-mentioned technological means is: when an impeller is assembled in this fan frame inner side and drives air-flow to carry out thermolysis, in the process of this air-flow by this stator blade respectively, can be difficult for producing the noise of identical vibration frequency, to reach the effect of the intensity of effective reduction single-frequency noise that respectively this stator blade was produced.
