'Opinion' Auto cooling fan 】 Install the difficulty level is different!
auto cooling fan is often installed in the air conditioning unit inlet and outlet, induced draft fan for boiler drum, and so on location, installation is more complex, axial flow fan is often installed in the duct, or duct export of front-end.
auto cooling fan is working, blade air moving in a direction perpendicular to the axis phase ( The radial) Flow, inlet is along the axis direction, and the gas is perpendicular to the axis direction. In most cases, the use of axial flow fan can achieve cooling effect, however, sometimes you rotate it 90 degree if need air discharge or need larger wind pressure, will choose centrifugal fan xu. Strictly speaking, fans are belong to the centrifugal fan.
auto cooling fan blade air moving in the same as the axis direction. Axial flow fan impeller and propeller is a bit similar, it at work, a large proportion of the air flow direction parallel to the axis, in other words, along the axis direction. Axial flow fan when the inlet air flow is 0 static free air, zui power loss is low, when running with airflow backpressure increases power consumption will increase. Axial flow fan is usually served on electrical equipment cabinets, sometimes integration on the motor, because of the axial flow fan, the structure is compact, can save a lot of space, easy installation at the same time, so widely used.
