Description
Technical field
This utility model is related to mechanical field, and in particular to a kind of New-type electric machine mixed flow fan.
Background technology
The effect of the interior circulation fan of medium-and-large-sized motor is to produce the gas of enough pressure and flow by motor internal,
The heat of motor internal is transported to carries out heat exchange in cooler, to reach the effect that cooling is forced to electric machine iron core and coil
Really.Therefore the structure of interior circulation fan also just affects the single-machine capacity of the radiating effect of motor, electric efficiency and motor.Tradition
Motor using interior circulation fan be centrifugal fan or tube-axial fan.Conventional centrifugal fan can produce higher wind
Pressure, but fan is inefficient；And the efficiency comparison of tube-axial fan is high, but blast is smaller.
Utility model content
This utility model purpose is to provide for a kind of processing simply, safe and reliable, efficiency high, the big medium-and-large-sized electricity of blast
Machine mixed flow fan.
To achieve these goals, this utility model is employed the following technical solutions：A kind of New-type electric machine mixed flow fan, bag
The fan base of cylindrical tube shape is included, circumference in equal parts is welded with least four lower blades on the periphery wall of the fan base, described
Lower blade is in arc-shaped, is fixed with the first fan board in the upper top cambered surface of the lower blade, first fan board it is annular in shape and
Concentric with the fan base, first fan board is in circular arc in the cross section on the fan base axis direction；Institute
The upper top cambered surface for stating lower blade is plane away from the end of the fan base, and the second fan board is fixed with the plane, described
Second fan board is in annulus lamellar, and second fan board is welded and fixed with the larger diameter distal end of first fan board, described
It is welded with blade above first fan board and the second fan board on plate, upper leaf piece is circular arc, upper leaf
Above go to the bottom cambered surface and first fan board and second fan board of piece, the surface of plate fits, upper leaf piece position
In the surface of the lower blade.
Preferably, the arc diameter of upper leaf piece and the lower blade is 480mm.
Preferably, the entrance established angle of upper leaf piece and the lower blade is 45 degree.
Preferably, the lower blade has eight, and same upper leaf piece has eight.
Preferably, the surface of the fan base, blade and lower blade is provided with anti-oxidation film layer.
Preferably, the two ends of upper leaf piece and the lower blade cut into vertical plane.
Preferably, the end of the cambered surface of going to the bottom of the lower blade cuts into plane.
This utility model is rational in infrastructure, by the shape for changing blade, effectively subtracts in the case of equal overall dimensions
Lack fan gas flow loss, improved work efficiency, reduced running noise, and process simple, low cost.
