Abstract
The utility model provides an internal fan of a double-permanent-magnet power-frequency brushless synchronous generator. The internal fan comprises a polysulfone plastic baseplate, polysulfone plastic wind blades and a polysulfone plastic cover plate, wherein the polysulfone plate baseplate and the polysulfone plastic cover plate are arranged front and back, the polysulfone plastic wind blades are fixedly connected between the polysulfone plastic baseplate and the polysulfone plastic cover plate, and the polysulfone plastic baseplate is provided with four kidney-shaped ventilation holes. Because the baseplate, the wind blades and the cover plate are all made of polysulfone plastic, the internal fan disclosed by the utility model has the advantages of light weight, corrosion resistance, no deformation and convenience for maintenance and replacement. An important air channel of the internal fan is formed by the four kidney-shaped ventilation holes on the baseplate, and thus the ventilation and heat radiation effects of the internal fan can be improved.
Description
Technical field
The utility model relates to a kind of pair of permanent magnetism power frequency no-brush synchronous generator internal fan, belongs to the Power generator fan technical field.
Background technique
The internal fan of existing generator all is made of metal usually, and use meeting throughout the year is out of shape because of corrosion or is ruptured.Metal internal fan is relatively heavier, and maintenance and replacing are all very inconvenient.
Summary of the invention
The purpose of the utility model is that use meeting throughout the year is out of shape because of corrosion or is ruptured for the internal fan that solves existing generator all is made of metal usually.Metal internal fan is relatively heavier, the problem that maintenance and replacing are all very inconvenient, and then a kind of pair of permanent magnetism power frequency no-brush synchronous generator internal fan is provided.
The purpose of the utility model realizes through following technological scheme:
The utility model comprises: polysulfone plastic base plate, polysulfone plastic air blade and polysulfone plastic cover plate; Be provided with before and after said polysulfone plastic base plate and the polysulfone plastic cover plate; Be fixedly connected with the polysulfone plastic air blade between polysulfone plastic base plate and the polysulfone plastic cover plate, have four waist shape vent holes on the polysulfone plastic base plate.
Can find out that by the above-mentioned technological scheme that provides the base plate of the utility model, air blade and cover plate are all processed by polysulfone plastic, have in light weight, anticorrosive, indeformable, safeguard and change all advantage very easily.Four waist shape vent holes on the base plate form the important wind path of internal fan, can improve the result of ventilating heat dissipation of internal fan.
Description of drawings
Fig. 1 is the structural representation of a kind of pair of permanent magnetism power frequency no-brush synchronous generator internal fan providing of the utility model mode of execution;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is the perspective view of two permanent magnetism power frequency no-brush synchronous generator internal fans.
Embodiment
To combine accompanying drawing that the utility model is done further detailed description below: present embodiment provided detailed mode of execution, but the protection domain of the utility model is not limited to following embodiment being to implement under the prerequisite with the utility model technological scheme.
Like Fig. 1～shown in Figure 3; A kind of pair of permanent magnetism power frequency no-brush synchronous generator internal fan that present embodiment is related; Comprise polysulfone plastic base plate 1, polysulfone plastic air blade 2 and polysulfone plastic cover plate 3; Said polysulfone plastic base plate 1 is provided with (concentric circle) with polysulfone plastic cover plate 3 front and back, is fixedly connected with polysulfone plastic air blade 2 between polysulfone plastic base plate 1 and the polysulfone plastic cover plate 3, has four waist shape vent holes 5 on the polysulfone plastic base plate 1.
Said four waist shape vent holes 5 are symmetrical set in twos.
Further, also comprise spacing collar 4, said spacing collar 4 is fixed on the back (another side of polysulfone plastic air blade 2) of polysulfone plastic base plate 1.
The quantity of said spacing collar 4 is four.
The above; Be merely the preferable embodiment of the utility model; These embodiments all are based on the different implementations under the utility model general idea, and the protection domain of the utility model is not limited thereto, and any technician who is familiar with the present technique field is in the technical scope that the utility model discloses; The variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain of claims.
