Abstract
It the utility model is related to a kind of generator cooling fan with negative-pressure inlet, including plate-like body, and it is arranged on plate-like body front and some blades in divergent shape uniformly, the blade outer end carries eave tile, overall is in " √ " shape, and rounding off at transition location, circle the first negative-pressure inlet hole and a second negative-pressure inlet hole of circle are provided with plate-like body, the first negative-pressure inlet hole position is set in the inner chamber that all blades surround and close to the inner side termination of blade, and the second negative-pressure inlet hole is arranged between the medial segment of adjacent blades.By being improved to blade construction, while increase negative-pressure inlet, be collectively forming dual-cooled wind, to increase the intake of cooling fan, improve cooling effect.
Description
Technical field
It the utility model is related to a kind of cooling fan, and in particular to a kind of cooling fan with negative-pressure inlet, be mainly used in
Generating set.
Background technology
For generator in work is run, it is more that inside produces heat, when temperature is higher, can influence matching somebody with somebody between each part
Close and run, therefore generator is equipped with cooling fan, promotes generator to carry out heat exchange with outside, makes in generator
Heat discharge generator outside, cold air is drawn into generator and cooled down again, so as to ensure generator-temperature detection stable and uniform,
Keep good working order.
But the cooling fan of generating set is now presently used for generally by plate-like body, and it is arranged on plate-like body just
The some of face are in that the blades that divergent shape is distributed form, and wind enters from plate-like body front, this through blade water conservancy diversion rear side to air-out
The structure intake of single side air inlet is small, and cooling effect is limited.
Utility model content
The utility model is intended to by being improved to blade construction, while increases negative-pressure inlet, to increase cooling fan
Intake, improve cooling effect.
Therefore, technical scheme is used by the utility model：A kind of generator cooling fan with negative-pressure inlet, including
Plate-like body, and be arranged on plate-like body front and carry eave tile in the uniform some blades of divergent shape, the blade outer end,
Overall be in " √ " shape, and rounding off at transition location, and circle the first negative-pressure inlet hole and one is provided with plate-like body and is enclosed
Second negative-pressure inlet hole, the first negative-pressure inlet hole position is in the inner chamber that all blades surround and close to the inner side termination of blade
Set, the second negative-pressure inlet hole is arranged between the medial segment of adjacent blades.
As the preferred of such scheme, the blade is odd number, and blade is perpendicular to plate-like body, and the thickness of blade is by root
Portion is gradually reduced towards the direction away from root.Odd Phases the blade stagger setting of fan both sides, will not be formed than even number blade
Convection current wind, reduce noise caused by echo.
Further, the first negative-pressure inlet hole is mounting hole, and two lines of centres of mounting hole are by plate-like body
Center；The second negative-pressure inlet hole is provided between the medial segment of adjacent blades.Optimize first, second negative-pressure inlet hole
Number and shape, further improve intake, reduce processing capacity.
Further, at least two mounting holes are additionally provided with the middle part of the plate-like body, for cooling fan itself
Installation.
The beneficial effects of the utility model are：Compared with traditional Power generator fan, fan blade uses outer side band eave tile
And " √ " shape structure of rounding off, to increase positive intake, while first negative pressure of circle is provided with plate-like body
Fresh air inlet and a second negative-pressure inlet hole of circle, make back side air intake form negative-pressure inlet, are collectively forming dual-cooled wind, and alleviate
It the weight of cooling fan, can farthest increase blast and air quantity, improve heat exchanger effectiveness, promote generator heat-radiation,
Ensure generator temperature stabilization, improve the power output of generator.

Into both are integrally formed.
Some blades 2 uniform in divergent shape are provided with the front of plate-like body 1, the outer end of blade 2 carries eave tile, is in integrally
" √ " shape, and rounding off at transition location, the convenient wind that cools down enter through blade medial extremity, and the air-flow surrounded through adjacent blades leads to
Behind road, lateral outflow cools down for generator.Wind direction is as shown by arrows in FIG..
The first negative-pressure inlet of circle hole 3 and a second negative-pressure inlet hole 4 of circle, the first negative pressure are provided with plate-like body 1
Fresh air inlet 3 is located in the inner chamber that all blades 2 surround and set close to the inner side termination of blade 2, and the second negative-pressure inlet hole 4 is set
Between the medial segment of adjacent blades 2.
Preferably, blade 2 is odd number, and blade 2 is perpendicular to plate-like body 1, and the thickness of blade 2 is by root towards away from root
Direction be gradually reduced.But the quantity of blade 2 is not limited to odd number or even number.
In addition, the first negative-pressure inlet hole 3 is preferably mounting hole, increase intake, and two lines of centres of mounting hole pass through
The center of plate-like body 1.A second negative-pressure inlet hole 4 is provided between the medial segment of adjacent blades 2, fresh air inlet 4 is as far as possible
Maximum is set, until close to the root of blade 2.
At least two mounting holes 5 are additionally provided with the middle part of plate-like body 1, the installation for cooling fan itself is fixed.
