Abstract
The invention provides a combined type structure for a fan, which comprises a motor formed by a coil and a rotor, a blade fixed or connected with the rotor and a shell with the grounding or noise-reducing functions; an advanced axial fan is adopted and the outlet of the axial fan is connected with the inlet of a centrifugal fan, and therefore the fan can satisfy the functions of the small ventilation volume, direction change angle and ventilation pressure difference.
Description
Technical field
The present invention relates to a kind of ventilator structure, especially the fabricated structure of ventilator.
Background technique
Present ventilator generally comprises motor that coil and rotor constitute, fixing or be connected the shell of epitrochanterian blade, ground connection or decrease of noise functions in structure, under large-scale ventilation and pipeline complex situations, blower fan has many-sided requirements such as direction and draught capacity, and common blower fan just can not satisfy the needs of variation.
Summary of the invention
The invention provides a kind of ventilator that can satisfy direction and ventilation.
For achieving the above object, technological scheme of the present invention is:
A kind of fabricated structure of ventilator, the motor that is made of coil and rotor, shell fixing or that be connected epitrochanterian blade, ground connection or decrease of noise functions are formed, it is characterized in that adopting the anteposition axial fan, the axial-flow blower outlet connects the import of centrifugal blower.
Ventilator just can satisfy ventilation, the angle that turns, function that leeway is little like this.
Embodiment
In concrete the enforcement,, can adopt Driven by Coaxial technology, save a motor, and make the joint contact relatively fine and close, form reliable connection, not cause the decay of energy loss and function to keep blast stable with motor according to as required.
In addition,, can keep flow velocity and ventilation like this, and not influence inside and outside air pressure balance, cause big negative pressuren zone, and bring other seondary effects by the unit combination of many groups if ventilation distance is long and tortuous many.
Claims (2)
1. the fabricated structure of a ventilator, the motor that is made of coil and rotor, shell fixing or that be connected epitrochanterian blade, ground connection or decrease of noise functions are formed, it is characterized in that adopting the anteposition axial fan, the axial-flow blower outlet connects the import of centrifugal blower.
2. according to claim 1, it is characterized in that adopting Driven by Coaxial technology with motor.
