In this extremely the development of society, there are many types of fan, fan are many ways of classification, such as according to the material classification, fan according to the direction of gas flow classification, according to the flow direction of the airflow into the impeller after classification, classified according to the use, according to the pressure in the form of classification, may be classified according to the wind pressure. The following key said the classified according to the direction of gas flow is how. 1, centrifugal fan, the fan in the work, airflow by axial fan into the blade space, and then under the drive of the impeller on the one hand, with the impeller rotation; On the other hand under the action of inertia, increase energy, leaving the impeller along radius direction, by centrifugal force generated by the fan of doing work is called the centrifugal fan. 2, the axial fan: use a very wide range, is the same direction of air flow and wind leaf axis, such as electric fans, air conditioning machine outside the fan is the way of axial flow fan operation. Known as the "axial flow", because gas flows parallel to the axial fan. 3, oblique flow, mixed flow fans: it is between axial flow fan and centrifugal fan fan, oblique flow fan impeller make air centrifugal exercise and axial movement, the enclosed air mixed with axial and centrifugal motion form. 4, cross-flow fan, the biggest characteristic of cross flow fan is a fluid flowing through the fan impeller twice, fluid along the radial flow along the radial flow, and then air intake and exhaust direction in the same plane, the exhaust gas along the width direction fan evenly distributed.
