The outflow separation caused by overlarge diverging proportion or deflection angle is avoided, so that extra reflux loss is generated, and the air outlet performance of the fan is effectively improved.
When the air outlet section is required to realize deflection air outlet with alpha more than or equal to 90 degrees, the air outlet section can be divided into three sections: the area ratio of each section needs to be kept in the relation range of the area ratio of the points, and the area change amplitude and the area change rate of the deflection section along the flow direction need to be lower than the level of the two straight sections. Therefore, the pipe network resistance of deflection air outlet is controlled, and the air outlet performance of the whole machine is improved.
When the flow of the air outlet section pipe is in a straight-in and straight-out form, the air outlet section pipe is in a variable cross-section form along the flow direction, and the area size is continuously and slowly changed, and the air outlet section pipe is concretely characterized in that: the area ratio relation is 0.3-1/S2-1.2, and the deflection angles at the two sides of the flow channel cannot be too large or too small: -10 ° < β <45 °, -10 ° < γ <45 °, |β|+|γ| <70 °. Therefore, the phenomenon that the outflow is not suffocated and the flow is greatly attenuated due to overlarge taper proportion is avoided; the outflow separation is not caused by the excessive diverging proportion or the offset angle, and the outflow must overcome the extra backflow loss of the two side walls.
