Abstract
This utility model relates to a kind of novel seal smoke exhaust fan, including inner core body, ring flange and end cap, it is characterized in that: described inner core body includes being positioned at the internal layer cylinder of inner side and is positioned at the outer layer barrel in outside, the end, one end of internal layer cylinder and outer layer barrel is fixing outside being connected with ring flange respectively, the other end end of internal layer cylinder is provided with described end cap, the other end end of outer layer barrel is opening, described internal layer cylinder sidewall is provided with some stamping forming shutter type louvres, and outer layer barrel is provided with some siphon holes corresponding with shutter type louvre；This utility model reasonable in design, use double layer design while being used for preventing flue gas from entering inner core body, the perforated area of shutter type louvre is greatly increased simultaneously, passively dispel the heat also by siphon hole while active heat removal, radiating efficiency is improved, has ensured the service life of motor.
Description
Technical field
This utility model relates to field of mechanical technique, particularly relates to a kind of novel seal smoke exhaust fan.
Background technology
Inner core body of the prior art is fixed on inside fire-protection high temp, and motor is arranged on inner core, and this is internal,
In order to ensure the stability of motor rotation, the outer wall of inner core body is provided with multiple louvre, and the perforated area of louvre is less,
The radiating efficiency causing novel seal smoke exhaust fan is low, reduces the service life of motor.
Summary of the invention
In order to solve deficiency of the prior art, the purpose of this utility model is to provide a kind of novel seal Smoke
Machine, radiating efficiency is high, and motor is long for service life.
This utility model solves its technical problem and be the technical scheme is that
A kind of novel seal smoke exhaust fan, including inner core body, ring flange and end cap, it is characterised in that: described inner core
Body includes the internal layer cylinder being positioned at inner side and is positioned at the outer layer barrel in outside, one end end portion of internal layer cylinder and outer layer barrel
Fixing outside not being connected with ring flange, the other end end of internal layer cylinder is provided with described end cap, the other end end of outer layer barrel
Portion is opening, and described internal layer cylinder sidewall is provided with some stamping forming shutter type louvres, if outer layer barrel is provided with
The dry siphon hole corresponding with shutter type louvre.
The beneficial effects of the utility model are: reasonable in design, use double layer design in being used for preventing flue gas from entering
While cylinder body, the perforated area of shutter type louvre is greatly increased simultaneously, also by siphon hole while active heat removal
Passively dispel the heat so that radiating efficiency is improved, ensured the service life of motor.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is sectional structure schematic diagram of the present utility model
In figure: 1 inner core body, 2 siphon holes, 3 outer layer barrels, 4 internal layer cylinders, 5 end caps, 6 shutter type louvres, 7 flanges
Dish.
Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model being described below, those skilled in the art can be by this
Content disclosed by description understands other advantages of the present utility model and effect easily.
As shown in Figure 1, 2: a kind of novel seal smoke exhaust fan, including inner core body 1, ring flange 7 and end cap 5, described
Inner core body 1 includes the internal layer cylinder 4 being positioned at inner side and is positioned at the outer layer barrel 3 in outside, internal layer cylinder 4 and outer layer barrel 3
End, one end is fixing outside being connected with ring flange 7 respectively, and the other end end of internal layer cylinder 4 is provided with described end cap 5, outer layer cylinder
The other end end of body 3 is opening, wherein can increase at internal layer cylinder 4 and outer layer barrel 3 according to actual needs and strengthen
Muscle, is used for ensureing that structural stability, described internal layer cylinder 4 sidewall are provided with some stamping forming shutter type louvres 6, hundred
Blade profile louvre 6 includes the multiple row of axial distribution, and each column shutter type louvre 6 is all by mould punching molding, on outer layer barrel 3
Being provided with some siphon holes 2 corresponding with shutter type louvre 6, the flue gas circulated by outside produces negative pressure, makes shutter type dispel the heat
The steam that hole 6 is discharged is sucked out, and simultaneously facilitates the steam in shutter type louvre 6 sucking-off internal layer cylinder 4, makes inner core body 1
Radiating efficiency is improved, and has ensured the service life of motor.
The foregoing is only preferred embodiments of the present utility model, as long as realizing this utility model with essentially identical means
Purpose technical scheme, within broadly falling into protection domain of the present utility model.
