Abstract
The utility model discloses a transshipment type lateral flow ventilation impeller which is suitable for the fields of low pressure ventilation, air conditioning, vehicles, household appliances, household machines, laser machinery, etc. The transshipment type lateral flow ventilation impeller comprises a shaft, a shaft sleeve, and an additional transshipment wheel which has a pitch range from 10 to 80 mm, wherein, both ends of the transshipment wheel are respectively connected with the shaft and the shaft sleeve. The utility model has the characteristics that the noise of blower fans can be effectively reduced, the aerodynamic characteristics of blower fans can be increased, etc.
Description
The utility model relates to a kind of crossing current ventilation impeller, and it is applicable to fields such as low pressure ventilation ventilation, air-conditioning, vehicle and household electric appliance, farm machinery, Laser Equipment.
In background technique, the crossflow fan impeller is formed a leafy rotor of taking turns of tubular by axle, axle sleeve, dividing plate and blade, air-flow is along the direction vertical with rotor axis, the leaf grating that forms from rotor one lateral lobe sheet enters impeller, pass vane rotor inside then, by the leaf grating of rotor opposite side air-flow is discharged for the second time, there is a vortex in its internal gas flow, affect the aerodynamic characteristic of blower fan, its eddy current crack and air-flow have constituted the main noise of blower fan to the impact noise of blade.For overcoming these defectives, it is improved.
The purpose of this utility model is that a kind of reprinting formula crossing current ventilation impeller will be provided, and it can reduce the noise of blower fan effectively, improves the aerodynamic characteristic of blower fan.
The purpose of this utility model is achieved in that
It comprises axle, axle sleeve,
It also comprise by its two ends respectively the pitch of coupling shaft and axle sleeve be the reprinting wheel of 10-80 millimeter.
It between the described reprinting wheel axially equidistant the connection.
Also can be axially between the described reprinting wheel and equidistantly do not connect.
Also can partly be axially equidistant the connection between the described reprinting wheel, part be for axially equidistantly connecting.
On the described reprinting wheel circumferentially uniform dividing plate is arranged.
The dividing plate that circumferential uneven distribution is arranged on the described reprinting wheel.
The dividing plate that partly circumferentially uniform and the circumferential uneven distribution of part are arranged on the described reprinting wheel.
Dividing plate on the described reprinting wheel is for facing plate directly.
Dividing plate on the described reprinting wheel also can be curved plate.
Block board thickness on the described reprinting wheel is the 0.5-5 millimeter, can be 1 millimeter, 2 millimeters etc.
The utility model is compared the good effect that is produced with background technique:
1, there be not the impact of air-flow to blade in the utility model owing to there is not blade, has greatly reduced noise.
2, the utility model is owing to be that the cavity of rely on reprinting between the wheel upper clapboard is carried to the side of giving vent to anger by the gas that rotatablely moves the air inlet side, in spiral case, produce pressure field, the merit of reprinting wheel rotation generation is changed into gas flow, have better aerodynamic characteristic.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a kind of structural drawing of reprinting wheel 3 of A-A among Fig. 1.
Fig. 3 is the structural drawing that the another kind of A-A among Fig. 1 is reprinted wheel 3.
Below in conjunction with accompanying drawing, the utility model is further described:
Axle sleeve 2 can adopt the rubber axle sleeve, and it is that tinsel, rubber, metal axle sleeve are formed, and links with motor in the blower fan, axle 1 can adopt metallic material, and match with bearing in the blower fan, length is not limit, and can crouch, can vertically lay, in the air channel, rotate, air-flow will enter impeller from a side along the vertical direction of rotor, through the reprinting wheel 3 drive air-flows of rotation, discharge from the opposite side of impeller, reprinting wheel 3 can be metal or nonmetallic material are made.
