Abstract
The utility model provides a heat dissipation impeller suitable for small -size digital frequency conversion generator with increase journey generator, the impeller body includes bottom plate, a plurality of flabellum, staple bolt, apron, its characterized in that: bottom plate, flabellum, staple bolt, apron integrated into one piece, the flabellum sets up on the bottom plate, and every flabellum equal some surpass the bottom plate, the staple bolt is cylindrical, the outer end of flabellum with the staple bolt links to each other, the apron is the ring, the outside of ring with the staple bolt links to each other, the apron with the flabellum links to each other, and lies in the opposite of bottom plate. The utility model discloses combine axial fan and centrifugal fan's advantage, when the impeller body rotated along with generator rotor, the flabellum was centrifugal flabellum, and the air current gets into the flabellum by the wind gap that the apron formed to along the direction with axial vertical motion, move when locating to the staple bolt when the air current, to understand along the staple bolt and change into axial motion, the wind pressure is big, and the radiating effect is good.
Description
Technical field
The utility model relates to a kind of component of cooling mechanism, particularly a kind of heat radiating fan wheel being applicable to small size digital frequency conversion generator and increasing journey generator.
Background technique
Current small size digital frequency conversion generator and increasing journey generator, along with the progressively maturation of its technology, occupy more and more consequence in small generator industry.Such generator normal configuration is compact, if the inner heat produced can not effectively be distributed in power generation operation process, then and can to producing infringement greatly in the stability of generator operation parts, reliability and working life.Therefore, cooling mechanism is component indispensable in generator.The cooling mechanism mainly fan used in this field at present, some employing axial fans, the employing centrifugal cutter had, and the use of axial fan is main flow, but there are some shortcomings in axial fan, topmost shortcoming is that blast is little, and the radiating effect that this type of flabellum brings in the generator that holding space is less is poor.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides that a kind of blast is strong, being applicable to small size digital frequency conversion generator and increasing the heat radiating fan wheel of journey generator of excellent in heat dissipation effect.
The utility model solves the technological scheme that its technical problem adopts:
Be applicable to a heat radiating fan wheel for small size digital frequency conversion generator and increasing journey generator, described impeller body comprises base plate, some flabellums, anchor ear, cover plate, it is characterized in that: described base plate, flabellum, anchor ear, cover plate are one-body molded; Described flabellum is arranged on described base plate, and each flabellum all some exceeds base plate; Described anchor ear is cylindrical, and the outer end of described flabellum is connected with described anchor ear; Described cover plate is annulus, and the outside of described annulus is connected with described anchor ear, and described cover plate is connected with described flabellum, and is positioned at the opposite of described base plate.
Preferably, described base plate is circular, and the center of circle of described base plate and plane are provided with multiple hole, for being arranged on generator amature.
Preferably, described flabellum has certain radian, and the end of some flabellums extends to anchor ear and is connected with cover plate with anchor ear.
The advantage of the utility model combined axis flow fan and centrifugal cutter, when impeller body rotates along with generator amature, flabellum is centrifugal flabellum, the air port that air-flow is formed by cover plate enters flabellum, and move along with axially vertical direction, after air-flow enters the region that cover plate and anchor ear formed, then moving direction is forced to change axial motion into, and the exhaust outlet formed along base plate and anchor ear flows out, blast is large, excellent in heat dissipation effect.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is a kind of front view being applicable to the heat radiating fan wheel of small size digital frequency conversion generator and increasing journey generator provided by the utility model.
Fig. 2 is a kind of stereogram being applicable to the heat radiating fan wheel of small size digital frequency conversion generator and increasing journey generator provided by the utility model.
Identify in figure, (1) flabellum; (2) base plate; (3) cover plate; (4) anchor ear.
Embodiment
As shown in Figure 1 and Figure 2, a kind of heat radiating fan wheel being applicable to small size digital frequency conversion generator and increasing journey generator disclosed in the utility model, comprise base plate (2), some flabellums (1), anchor ear (4), cover plate (3), described base plate (2), flabellum (1), anchor ear (4), cover plate (3) are one-body molded; Described flabellum (1) is arranged on described base plate (2), and each flabellum (1) all some exceeds base plate (2); Described anchor ear (4) is for cylindrical, and the outer end of described flabellum (1) is connected with described anchor ear (4); Described cover plate (3) is annulus, and the outside of described annulus is connected with described anchor ear (4), and described cover plate (3) is connected with described flabellum (1), and is positioned at the opposite of described base plate (2).Described base plate (2) is circular, and the large face of described base plate (2) is provided with multiple hole for being arranged on generator amature.
The advantage of the utility model combined axis flow fan and centrifugal cutter, when impeller body rotates along with generator amature, flabellum is centrifugal flabellum, the air port that air-flow is formed by cover plate enters flabellum, and move along with axially vertical direction, after air-flow enters the region that cover plate and anchor ear formed, then moving direction is forced to change axial motion into, and the exhaust outlet formed along base plate and anchor ear flows out, blast is large, excellent in heat dissipation effect.
Should be understood that, for a person skilled in the art, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to the utility model claims.
