Description
Technical field
A kind of square tube symmetric type blower fan, relates to a kind of blower fan, particularly relates to a kind of square tube blower fan.
Background technique
Traditional axial-flow blower is columnar, and the plane of rotation of its blade is vertical with the opening direction of shell, and external diameter is comparatively large, and sectional area is comparatively large, is inconvenient to the narrow space being installed on flat.Traditional single motor fan moment of torsion is comparatively large, fixedly mounts more difficult.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of square tube symmetric type blower fan being easily installed in flat narrow space is provided.
Technological scheme of the present invention is: a kind of square tube symmetric type blower fan, comprises left motor, left fan blade, left socle, right motor, right fan blade, right support, square-tube-shaped shell and guide plate.Left motor is identical with right motor, left fan blade and right blade structure and measure-alike.Left motor is arranged on the left side of the inside of square-tube-shaped shell by left socle; Right motor is arranged on the right side of the inside of square-tube-shaped shell by right support.Left fan blade is arranged on the output shaft of left motor, and right fan blade is arranged on the output shaft of right motor.Left fan blade and right fan blade symmetry are arranged on the left and right sides of square-tube-shaped enclosure.Square-tube-shaped shell is surrounded by four pieces of flat boards up and down, upper and lower two pieces of platen parallel, two pieces, left and right platen parallel, upper and lower two pieces of flat boards and two pieces, left and right slab normal.The plane of rotation of left fan blade and the plane of rotation of right fan blade all with upper and lower slab normal; Plane of rotation and the left plate of left fan blade acutangulate, and plane of rotation and the right flat board of right fan blade acutangulate; The angle of the plane of rotation of left fan blade and the plane of rotation of right fan blade is not more than 150 °.The section of left fan blade and right fan blade is all aerofoil profile.The inner circumferential of the transverse section of square-tube-shaped shell is rectangular, this rectangular wide namely width that left and right is dull and stereotyped is a bit larger tham maximum outside diameter when left fan blade rotates with left motor output shaft, the namely up and down dull and stereotyped width of this rectangular length is a bit larger tham both product following: maximum outside diameter sum when maximum outside diameter when left fan blade rotates with left motor output shaft and right fan blade rotate with right motor output shaft, the sine value of acute angle formed by the plane of rotation of left fan blade and the left plate of square-tube-shaped shell.Left fan blade and right fan blade are near installing but can not touching, and left fan blade and right fan blade all can rotate neatly in square-tube-shaped shell, the direction of rotation of left fan blade and right fan blade, torque of cancelling out each other.Left motor and right motor are all in the upstream of air-flow.Guide plate is installed on the outlet port of square-tube-shaped shell and the rear end of square-tube-shaped shell.
For raising the efficiency, the minimum clearance between the maximum outside diameter that left fan blade rotates and the inwall of square-tube-shaped shell is not more than 2mm.
A kind of square tube symmetric type of the present invention blower fan is work like this, the left fan blade of left motor driving rotates, the right fan blade of right motor driving rotates, then left fan blade and right fan blade are extruded in the gas inspiration square-tube-shaped shell in front from the rear of square-tube-shaped shell, and air-flow exports more stable under the effect of guide plate.Because left motor and right motor are in the upstream of air-flow, accelerated air-flow is less at the rear resistance of left fan blade and right fan blade.The minimum clearance of the inwall of the maximum outside diameter rotated due to left fan blade and square-tube-shaped shell is less, and left fan blade and right fan blade lean on close, therefore the efficiency of this blower fan is higher.
The advantage of a kind of square tube of the present invention symmetric type blower fan is: compared with traditional axial-flow blower, when flow is identical, the cross section of blower fan of the present invention is less, and efficiency is similar with traditional axial-flow blower; Blower fan of the present invention is easily installed in narrow space.Compared with traditional single motor drive shaft flow fan, moment of torsion is less, and installation means of fixation is simple and convenient.

Embodiment
Below in conjunction with accompanying drawing, the present invention is illustrated: with reference to accompanying drawing, a kind of square tube symmetric type blower fan, comprises left motor 1, left fan blade 2, left socle, right motor 3, right fan blade 4, right support, square-tube-shaped shell 5 and guide plate 6.Left motor 1 is identical with right motor 3, left fan blade 2 and right fan blade 4 structure and measure-alike.Left motor 1 is arranged on the left side of the inside of square-tube-shaped shell 5 by left socle; Right motor 3 is arranged on the right side of the inside of square-tube-shaped shell 5 by right support.Left fan blade 2 is arranged on the output shaft of left motor 1, and right fan blade 4 is arranged on the output shaft of right motor 3.Left fan blade 2 and right fan blade 4 symmetry are arranged on the left and right sides of square-tube-shaped shell 5 inside.Square-tube-shaped shell 5 is surrounded by four pieces of flat boards up and down, upper and lower two pieces of platen parallel, two pieces, left and right platen parallel, upper and lower two pieces of flat boards and two pieces, left and right slab normal.The plane of rotation of left fan blade 2 and the plane of rotation of right fan blade 4 all with upper and lower slab normal; The plane of rotation of left fan blade 2 becomes 50 ° of angles with left plate, the plane of rotation of right fan blade 4 becomes 50 ° of angles with right flat board; The angle α of the plane of rotation of left fan blade 2 and the plane of rotation of right fan blade 4 is 100 °.The section of left fan blade 2 and right fan blade 4 is all aerofoil profile.The inner circumferential of the transverse section of square-tube-shaped shell 5 is rectangular, this rectangular wide namely width that left and right is dull and stereotyped is a bit larger tham left fan blade 2 with maximum outside diameter during left motor 1 output shaft rotation, and the namely dull and stereotyped up and down width of this rectangular length is a bit larger tham left fan blade 2 and is multiplied by sin50 ° amassing with maximum outside diameter during left motor 1 output shaft rotation and right fan blade 4 again with maximum outside diameter sum during right motor 3 output shaft rotation.Left fan blade 2 and right fan blade 4 are near installing but can not touching, and left fan blade 2 and right fan blade 4 all can rotate neatly in square-tube-shaped shell 5, the direction of rotation of left fan blade 2 and right fan blade 4, torque of cancelling out each other.Left motor 1 and right motor 3 are all in the upstream of air-flow.Guide plate 6 is installed on the outlet port of square-tube-shaped shell 5 and the rear end of square-tube-shaped shell 5.Minimum clearance between the maximum outside diameter that left fan blade 2 rotates and the inwall of square-tube-shaped shell 5 is 2mm.
This blower fan is work like this: left motor 1 drives left fan blade 2 to rotate, and right motor 3 drives right fan blade 4 to rotate, and then left fan blade 2 and right fan blade 4 are extruded in the gas inspiration square-tube-shaped shell 5 in front from the rear of square-tube-shaped shell 5 at guide plate 6.
