Abstract
The utility model relates to a fan, in particular to a pressurizing fan. The pressurizing fan comprises a fan frame, a motor fixing seat fixed to the center of the fan frame and a motor fixed in the motor fixing seat. Blades are fixed to a motor output shaft, air guide sheets are further fixed to the air outlet end of the fan frame, one end of each air guide sheet is fixed to the inner wall of the fan frame, the other end of each air guide sheet is fixed to the outer wall of the motor fixing seat, the air guide sheets are in a curved arc shape, and the concave arc directions of the air guide sheets are opposite to the concave arc direction of the blades. Due to the fact that the curved-arc-shaped air guide sheets with the arc directions opposite to the concave arc directions of the blades are fixed to an air outlet of the fan, airflow guided out through the blades is reflected by the air guide sheets and forms cyclone-shaped airflow. As is proved by experimental tests, under the equal wind speed condition, the wind pressure of a cyclone can be 30% larger than common linear wind pressure, the effect of pressurization is achieved, and therefore the power consumption of the motor can be reduced, and energy is saved.
Description
Technical field
The utility model relates to a kind of fan, especially a kind of boosting type fan.
Background technique
Existing fan generally comprises fan frame, is fixed on the motor of fan frame central authorities, and be fixed on the flabellum on described motor output shaft, described fan frame defines a contrary wind inlet and an exhaust outlet, and driven by motor flabellum rotates and makes air-flow suck and discharge to reach the effect of heat radiation from wind sealing from wind inlet.
Although existing fan has certain radiating effect, but along with scientific and technological prosperity, the volume of electronic product is more and more less in recent years, cause produced heat to be more and more difficult for getting rid of, therefore, people have to propose the radiating efficiency that various technology improve fan.Generally the method for the most common radiating efficiency, for increasing the rotating speed of this motor, realizes sucked of increase with this and improves radiating efficiency with the air-flow of being discharged, yet, the power consumption when rotating speed of quickening motor will increase this fan running.
Model utility content
The utility model object be to provide a kind of in equal power consumption condition exportable larger blast, reach the force(d) (draft) fan of better radiating effect.
For achieving the above object, technical solution adopted in the utility model is: a kind of force(d) (draft) fan, comprise fan frame, be fixed on the motor fixing seat of described fan frame central authorities, and be fixed on the motor in described motor fixing seat, on described motor output shaft, be fixed with flabellum, the air opening end of described fan frame is also fixed with guide vane, the inwall of described fan frame is fixed in described guide vane one end, the other end is fixed on the outer wall of described motor fixing seat, and described guide vane becomes arc shape, its concave arc direction is relative with the concave arc direction of described flabellum.
According to the utility model of above structure, its further technical characteristics is also, the rearward end of described motor fixing seat is fixedly connected with described fan frame by guide vane, the front end plug-in mounting of described motor fixing seat is fixed with motor, described motor output shaft stretches out in outside described motor fixing seat, is fixed with flabellum on motor output shaft.
Because the utility model is provided with the arc shape guide vane relative with the concave arc direction of flabellum at the exhaust outlet of fan, thereby the air-flow that flabellum is derived forms the air-flow of whirlwind shape after the reflecting action of guide vane, through experiment test, prove, under equal wind friction velocity, the comparable common lineal shape blast of blast of whirlwind is large more than 30%, reach the effect of supercharging, therefore can reduce the power consumption of motor, saved energy.

Fig. 2 is the utility model guide vane three-dimensional structure diagram.
Embodiment
For making the utility model embodiment's object, technological scheme and advantage clearer, below in conjunction with the accompanying drawing in the utility model embodiment, technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiments.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figures 1 and 2, a kind of force(d) (draft) fan described in the utility model, comprises fan frame 1, is fixed on the motor fixing seat 2 of described fan frame 1 central authorities, and is fixed on the motor (not shown) in described motor fixing seat 2.The rearward end of described motor fixing seat 2 is fixedly connected with described fan frame 1 by guide vane 4, the front end plug-in mounting of described motor fixing seat 2 is fixed with motor, described motor output shaft stretches out in outside described motor fixing seat 2, is fixed with the intake grill end that flabellum 3 forms fan frame 1 on motor output shaft.The air opening end of described fan frame 1 is guide vane 4 fixedly, the inwall of described fan frame 1 is fixed in described guide vane 4 one end, the other end is fixed on the outer wall of described motor fixing seat 2, and 4 one-tenth arc shapes of described guide vane, (the fan frame of guide vane and guide vane part is only shown for clarity in Fig. 2, has omitted the fan frame of flabellum and flabellum part) as shown in Figure 2.Described guide vane 4 concave arc directions are relative with the concave arc direction of described flabellum 3, therefore, when flabellum 3 rotation, the flabellum of concave arc shape is sucked air-flow by intake grill end, air-flow travels forward and runs into the guide vane of concave arc shape, and the air-flow that guide vane reflects to form whirlwind shape by air-flow to air opening end blows out, and realizes the effect that increases blast, therefore reach the power consumption that reduces motor, the object of saving energy.
