Abstract
The utility model discloses a brushless condensation fan, which comprises a rotating shaft, wherein one end of the rotating shaft is provided with a hub, the outer circumference surface of the hub is connected with six blades, the width of the blades is 180mm-220mm, and the diameter ratio of the outer circumferences of the hub and the blades is 0.369. The brushless condensation fan disclosed by the utility model has small working noises and a large air volume.
Description
Technical field
The utility model relates to brushless condensation fan.
Background technique
Present brushless condensation fan comprises running shaft, at an end of running shaft wheel hub is installed, and blade is installed on the wheel hub, and described blade all is an odd number.Bearing is installed on running shaft, on the outer ring of bearing motor is installed, motor comprises stator and rotor, and stator is installed on the outer ring of bearing, and rotor is located at outside the stator, and rotor is connected with axial rotary; Be connected with support on the described stator.The condensation fan of this structure is owing to adopt odd number of blades, and therefore, noise is big.
Summary of the invention
The purpose of this utility model provides a kind of brushless condensation fan, and technical problem to be solved is the noise when reducing blower fan work.
For achieving the above object, the brush condensation fan comprises running shaft, and an end of running shaft is equipped with wheel hub, it is characterized in that: be connected with 6 blades on the outer peripheral surface of wheel hub, the width of blade is 180mm～220mm; Wheel hub is 0.369 with the diameter ratio of blade excircle.
As improvement, bearing is installed on the running shaft, on the outer ring of bearing motor is installed, motor comprises stator and rotor, and stator is installed on the outer ring of bearing, and rotor is located at outside the stator, and rotor is connected with axial rotary; Be connected with support on the described stator.
As improvement, be positioned at the outer air guide sleeve that is provided with of blade tip on the described support.
As specializing, be positioned at the outer air guide sleeve that is provided with of blade tip on the described support.
The beneficial effect of brushless condensation fan of the present utility model is: owing to adopt 6 blades, and the width of blade is 180～220mm, and therefore, the blower fan noise that works together is little.Owing to be provided with air guide sleeve, therefore, the energy of blade tip is not easy to scatter and disappear, and the air quantity of work is big; Blower fan of the present utility model is the axial-flow blower of a mixed-flow, has both had high efficiency, the low noise of centrifugal fan, has the characteristics of the big air quantity of axial fan simultaneously, so select even number sheet blade and uniform layout.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
Brushless condensation fan as shown in Figure 1 to Figure 3 comprises running shaft 1, and the middle part of running shaft 1 is equipped with bearing 2, on the outer ring of bearing 2 motor is installed, motor comprises stator 31 and rotor 32, and stator 31 is installed on the outer ring of bearing, rotor 32 is located at outside the stator, and rotor is connected with running shaft 1; Support 4 is installed on the stator 31, Direct box 5 is installed on the support 4, an end of running shaft 1 is equipped with wheel hub 6, is connected with 6 blades 7 on the outer peripheral surface of wheel hub 6, and the width of described blade is 180～220mm, and in the present embodiment, the width of blade is 201mm.Be positioned at the outer air guide sleeve that is provided with of blade tip on the described support, make the energy of blade tip be not easy to scatter and disappear, the air quantity of work is big.
The working procedure of brushless condensation fan is: Direct box 5 control motor rotations, and when motor rotation, 1 rotation of rotor 32 driven rotary axles, running shaft 1 drives the wheel hub rotation, and wheel hub drives blade 7 rotations.Owing to adopt 6 blades, and the width of blade is 201mm, and therefore, blower fan works together, and noise is little, air quantity is big.Following table is the contrast of blower fan of the present utility model and noise generated size of 5 blade blower fans and air quantity size.
Blower fan of the present utility model is the axial-flow blower of a mixed-flow, has both had high efficiency, the low noise of centrifugal fan, has the characteristics of the big air quantity of axial fan simultaneously, so select even number sheet blade and uniform layout.The wheel hub of blower fan is 0.369 with blade excircle diameter ratio, so select even number sheet blade and uniform layout, if ratio＜0.4, blade quantity is chosen between 4～8, and is the even number sheet.
