Embodiment
Preferred implementation of the present utility model is described in detail below in conjunction with accompanying drawing.
In order to reach the purpose of this utility model, as Figure 1-4, be applied in the some of them mode of execution of the cooling fan structure of generator of the present utility model, skeleton 1 is arranged multiple blade 2, multiple blade 2 by skeleton 1 outer ring 11 wherein the heart helically enter, and the height of this blade 2 by skeleton 1 outer ring 11 wherein the heart progressively reduce, on skeleton 1, form center recess 21 by this blade 2, the rotation output block 3 of generator is connected in this center recess 21.
The center recess 21 that the blade 2 arranged by spiral is formed on skeleton 1 central position, when fan turns, the air of fan center flows out to fan surrounding in the effect of centrifugal force, fan now wherein heart depressed part 21 forms vacuum environment, wind near center recess 21 on fan under the effect of atmosphere negative pressure starts again to flow to fan surrounding, form wind constantly to circulate back and forth, on the one hand the air quantity of fan can be strengthened thus, the wind part simultaneously constantly circulated in fan center and fan surrounding can enter into generator, simultaneously when fan center distinguished and admirable go out fan time, fan four weekly assembly forms certain negative pressure, the wind of fan surrounding is simultaneously also to fan center flow, flowing is formed with the wind of this drive electrical generators outside, come the outside of cooled electric generator, the inside and outside of generator is made to be cooled thus.
Wherein, in order to add the intensity of strong wind fan, fan can adopt nylon structure, proof strength and certain heat resistance.
Center recess 21 can be formed in several ways, introduce a kind of by changing blade 2 shape and constructing the mode forming this center recess 21 below, as shown in Figure 1-2, one end of blade 2 is formed centrally slope 22 in skeleton 1, the slope 22 of multiple blade 2 is formed centrally convergence in skeleton 1, and form center recess 21, the part of this slope 22 preferably in center recess 21 can also have the cambered surface of indent, to be more convenient for the flowing of wind, to form vacuum environment.
As Figure 1-3, blade 2 is at the ridge 23 of formation mountain peak, the jointing place shape of its body and slope 22, multiple ridge 23 can also with circle form (in Fig. 3 shown in dotted line) arrangement, the diameter of this circle can also be 1/2nd of outer ring 11 diameter of skeleton 1, outer ring 11 can be made to be in a most suitable distance to the distance of center recess 21, be unlikely to affect air quantity apart from too little, cause air leakage phenomena too greatly.
As Figure 2-3, the space between the outer ring 11 of skeleton 1 and its center is separated into multiple space cell 13 by multiple blade 2, and multiple space cell 13 forms multiple space cell group 12, includes multiple space cells 13 that width is different in space cell group 12.Wherein, particularly, space cell group 12 can comprise the first space cell 131, second space unit 132, the 3rd space cell 133, the 4th space cell 134 and the 5th space cell 135, the width of the first space cell 131 is minimum, second space unit 132 is identical and maximum with the width of the 5th space cell 135, and the width of the 3rd space cell 133 and the 4th space cell 134 is identical and between the width of the width of the first space cell 131 and second space unit 132, the 5th space cell 135.
By the setting of this structure, wind can be made when the space cell by different in width, air quantity increase progressively can be made, during particular by the 5th space cell 135, can by more air quantity, by the 3rd space cell 133 and the 4th space cell 134, two strands of wind can be divided into, after addition, increase air quantity further, after this again by the first space cell 131 and second space unit 132, by a little large setting, again increase air quantity.
As Figure 1-3, center recess 21 is provided with suit parts 4, and these suit parts 4 are for connecting the rotation output block 3 of generator.Wherein, particularly, the swivel nut 42 that parts 4 can comprise 41 both sides nested with being positioned at center, center nested 41 is set with.Center nested 41 can also adopt metal material, guarantees installation strength, and nested longitudinal section, center can also be isosceles trapezoid, also can guarantee installation strength.
Working procedure of the present utility model is introduced: emphasis arrow indication as Figures 1 and 4 below in conjunction with Fig. 1-4, after rotating the rotation of output block 3 drive fan, the air of the center recess 21 of fan flows out to fan surrounding in the effect of centrifugal force, fan now wherein heart depressed part 21 forms vacuum environment, wind near center recess 21 on fan under the effect of atmosphere negative pressure starts again to flow to fan surrounding, form wind constantly to circulate back and forth, part wind enters into generator, simultaneously when center recess 21 distinguished and admirable go out fan time, fan four weekly assembly forms certain negative pressure, the wind of fan surrounding also flows to center recess 21 simultaneously, flowing is formed with the wind of this drive electrical generators outside.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
