Description
Technical field
A kind of electronic disk of conical profile blower fan, relates to a kind of blower fan, particularly relates to a kind of electronic disk of conical profile blower fan.
Background technique
The blade of traditional axial-flow blower is substantially at the rotation with in surface vertical with rotating shaft, and external diameter is comparatively large, and sectional area is comparatively large, is inconvenient to be installed on narrow space.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of electronic disk of conical profile blower fan being easily installed in narrow space is provided.
Technological scheme of the present invention is: a kind of electronic disk of conical profile blower fan, comprises motor, support, disk of conical profile and tubular shape shell.Motor is fixed on support, and support is connected with tubular shape shell.Motor is arranged between two parties in the diametric(al) of tubular shape shell.The output shaft of motor is consistent with the opening direction of tubular shape shell.Disk of conical profile comprises front end disk, rear end annulus and several identical blade be evenly distributed.The section of blade is aerofoil profile.Vaned root is all arranged on the disk of front end, and vaned tip is all arranged on the annulus of rear end.The length direction of blade and the angle axially at the rear of front end disk of motor are acute angle.The front end disk of disk of conical profile is connected with the output shaft of motor.There is a horn mouth front end of tubular shape shell, facilitates air-flow to enter.Motor is in the front of disk of conical profile, and motor exposes to the front of tubular shape shell.Disk of conical profile is in tubular shape enclosure completely.
For raising the efficiency, the internal diameter of tubular shape shell is a bit larger tham the external diameter of the rear end annulus of disk of conical profile.The difference of the external diameter of the internal diameter of tubular shape shell and the rear end annulus of disk of conical profile is between 1 ~ 3mm.The length direction of blade and the axial of motor are not more than 80 ° at the angle at the rear of front end disk.Support adopts tripod.
A kind of electronic disk of conical profile blower fan of the present invention is work like this, and driven by motor disk of conical profile rotates, and then blade is extruded in the gas inspiration tubular shape shell in front from the rear of tubular shape shell.Because motor is in the upstream of air-flow, air-flow can not be subject to the resistance of motor by the process that disk of conical profile accelerates to flow backward, therefore this fan efficiency is higher.The tip of blade is near the inwall of tubular shape shell, the angle of the inwall of blade and tubular shape shell is acute angle, and forwards, gas in this angle is blown to the mid-rear portion of tubular shape shell to the opening of this angle by blade, under the vaned acting in conjunction of institute, gas is pressed against rear.
The advantage of a kind of electronic disk of conical profile blower fan of the present invention is: compared with traditional axial-flow blower, when flow is identical, the external diameter of blower fan of the present invention is much smaller, and efficiency is similar with traditional axial-flow blower; Blower fan of the present invention is easily installed in narrow space.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of electronic disk of conical profile blower fan of the present invention, and Fig. 2 is the plan view of Fig. 1.In figure: 1 is motor, 2 is support, and 3 is disk of conical profile, and 31 is front end disk, and 32 is blade, and 33 is rear end annulus, and 4 is tubular shape shell, and 5 represent streamline.
Embodiment
Below in conjunction with accompanying drawing, the present invention is illustrated: with reference to accompanying drawing, a kind of disk of conical profile blower fan, comprises motor 1, support 2, disk of conical profile 3 and tubular shape shell 4.Motor 1 is fixed on support 2, and support 2 is connected with tubular shape shell 4.Motor 1 is arranged between two parties in the diametric(al) of tubular shape shell 4.The output shaft of motor 1 is consistent with the opening direction of tubular shape shell 4.Disk of conical profile 3 comprises front end disk 31, rear end annulus 33 and several identical blade 32 be evenly distributed, and the section of blade 32 is aerofoil profile.The root of all blades 32 is all arranged on front end disk 31, and the tip of all blades 32 is all arranged on rear end annulus 33.The length direction of blade 32 and the angle axially at the rear of front end disk 31 of motor 1 are 60 ° of angles.The front end disk 31 of disk of conical profile 3 is connected with the output shaft of motor 1.The external diameter 1mm larger than the internal diameter of tubular shape shell 4 of the rear end annulus 33 of disk of conical profile 3.It is inner that disk of conical profile 3 is in tubular shape shell 4 completely.Motor 1 is in the front of disk of conical profile 3, and motor 1 exposes to the front of tubular shape shell 4.There is a horn mouth front end of tubular shape shell 4.The output shaft of motor 1 is parallel with the opening direction of tubular shape shell 4.Support 2 adopts tripod.
This blower fan is work like this: motor 1 drives disk of conical profile 3 to rotate, and then blade 32 is extruded in the gas inspiration tubular shape shell 4 in front from the rear of tubular shape shell 4.Because motor 1 is in the upstream of air-flow, air-flow can not be subject to the resistance of motor 1 by the process that disk of conical profile 3 accelerates backward rear flowing, therefore this fan efficiency is higher.The tip of blade 32 is near the inwall of tubular shape shell 4, because the output shaft of motor 1 is consistent with the opening direction of tubular shape shell 4, blade 32 is 60 ° with the angle of the inwall except horn mouth of tubular shape shell 4, the opening of this angle forwards, gas in this angle is blown to the mid-rear portion of tubular shape shell by blade 32, under the acting in conjunction of all blades 32, gas is pressed against rear and exports.
