Abstract
The utility model discloses an impeller device of a fan, which comprises a front chassis and a rear chassis, wherein the front chassis is provided with an air inlet, an arc-shaped blade is arranged between the front chassis and the rear chassis, and the inner end point of the arc-shaped intersection line of the blade and the front chassis moves forwards in the direction of the windward side, so that the blade body is in a distorted arc shape; the utility model discloses a blade adopts cubic rule, according to the aerodynamic principle, the flow trajectory of simulation gas in the fan twists into the 3D curved surface ordinary arc blade, under the same power, can increase the amount of wind and the static pressure of fan to improve fan efficiency, the energy saving.
Description
Technical field
The utility model relates to a kind of impeller unit of blower fan.
Background technique
At present, the impeller bodies of institute's use blower fan includes front chassis and rear chassis on the market, front chassis is provided with intake grill, the arc shaped blade that is provided with between front chassis and the rear chassis, the intersection line of arc shaped blade and front chassis and rear chassis is arc, and the radian of two arc intersection linees and position are identical, during wheel rotation, air enters impeller inside from the intake grill on the front chassis, under the effect of blade, discharges to centrifugal direction the air channel between blade.But, because that the shape of blade and air enter the interior flow trace of impeller is not exclusively identical, make air when the impeller internal flow and the flow resistance between the blade bigger, thereby increased the noise of air draft, reduced the ventilation efficiency of blower fan.
Summary of the invention
The purpose of this utility model is: the impeller unit that a kind of blower fan is provided, this device moves forward the interior end points of the arc intersection line of blade and front chassis to the windward side direction, make blade body be the arc shaped surface of distortion, the flow trace of shape and air fits like a glove, to reduce the flow resistance between air and the blade, increase the exhaust air rate of blower fan, reduce the noise of blower fan, improve the ventilation efficiency of blower fan.
The technical solution of the utility model is: a kind of impeller unit of blower fan, comprise front chassis and rear chassis, front chassis is provided with intake grill, be provided with arc shaped blade between front chassis and the rear chassis, the interior end points of the arc intersection line of described blade and front chassis makes blade body be the arc of distortion to the direction reach of windward side.
The utility model has the advantages that:
The utility model moves forward the direction of interior end points to the windward side of the arc intersection line of blade and front chassis, make blade body be the arc shaped surface of distortion, the flow trace that blade shape after the distortion and air enter in the impeller bodies fits like a glove, reduce the flow resistance between air and the blade, increased the exhaust air rate of blower fan, reduce the noise of blower fan, improved the ventilation efficiency of blower fan integral body.
Description of drawings
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is a stereogram of the present utility model;
Fig. 2 is a perspective view of the present utility model;
Fig. 3 is the plan view of the utility model blade;
Fig. 4 is the stereogram of the utility model blade.
Wherein: 1 front chassis; 2 rear chassis; 3 blades; 4 intake grills; 5 arc intersection linees; End points in 6; 7 windward sides.
Embodiment
Embodiment: as shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of impeller unit of blower fan, comprise front chassis 1 and rear chassis 2, front chassis 1 is provided with intake grill 4, be provided with arc shaped blade 3 between front chassis 1 and the rear chassis 2, described blade 3 moves forward with the direction of interior end points 6 to windward side 7 of the arc intersection line 5 of front chassis 1, makes blade 3 bodies be the arc of distortion.
