The utility model provides a current mixed flow the fan low and big problem of work noise of work efficiency of airing exhaust.
Description
Technical field
The utility model relates to ventilation equipment technical field, particularly relates to a kind of high-efficiency mixed flow blower fan.
Background technique
The general airflow direction according to impeller of blower fan is classified, the airflow direction of axial-flow blower is to be basically parallel to the flowing of blower fan axial direction, the air-flow of pipeline centrifugal blower enters from the axis of impeller, discharge from the radial direction of impeller after changing direction, flow-mixing blower fan is the product between axial-flow blower and centrifugal blower, it combines the optiaml characteristics of axial-flow blower and centrifugal blower, there is high transfer efficiency, wide pressure range, the air of flow-mixing blower fan axially enters impeller, and by impeller blade with a tilt angle deflection, make from the existing axial component of impeller effluent air, also radial component is had, two very important factors when the sound level produced in the efficiency of blower fan and working procedure is Fan Selection, be used for weighing the performance of blower fan, there is the problem that ventilation efficiency is low and operational noise is large in existing flow-mixing blower fan.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of high-efficiency mixed flow blower fan, solves existing flow-mixing blower fan air draft inefficiency and the large problem of operational noise.
The utility model is achieved through the following technical solutions: a kind of high-efficiency mixed flow blower fan, comprise engine housing and be arranged on the drive motor in engine housing, one end of described engine housing is intake grill, the other end is exhaust outlet, and at the internal surface of engine housing, evenly distributing fin being set, the surface of described drive motor arranges spiral radiator, and the front end rotating shaft of described drive motor connects wind wheel, the ear end face of drive motor arranges round platform, and the side surface of round platform is circular arc concave surface.
Further, the air inlet of described engine housing arranges tubaeform outer enlarging.
Further, the exhaust outlet inner side surface of described engine housing arranges bloop.
Further, the both sides of described drive motor arrange the fixed block be connected with engine housing internal surface.
Further, described wind wheel corresponding engine housing intake grill end face arranges centrifugal film, wind wheel corresponding engine housing exhaust outlet end face arranges axial flow sheet.
Compared with prior art, the beneficial effects of the utility model are: the utility model is by arranging tubaeform outer enlarging in the air inlet of engine housing, and at the internal surface of engine housing, evenly distributing fin is set, the round platform that side surface is circular arc concave surface is set at drive motor ear end face simultaneously, in conjunction with the wind wheel in drive motor rotating shaft, when starting blower fan, the intake grill end of engine housing can be made to be formed distinguished and admirable fast, and the distinguished and admirable intake grill from engine housing is through engine housing, and discharge distinguished and admirable rapidly from exhaust outlet, effectively improve blower fan working efficiency, the radiating fin on the surface of drive motor is arranged to spirality simultaneously, not only play the effect of motor radiating, and helical design is of value to distinguished and admirable formation, further increase blower fan working effect, bloop is set at the exhaust outlet inner side surface of engine housing simultaneously, effectively reduce the operating noise of blower fan.
