At present, the voltage of the fan we produce is DC voltage, and a fixed electronic switch (such as Hall IC) is used to replace the brush, and the current switch is implemented to drive the rotor to continue to run. It is called a "DC brushless fan", also called "DC axial fan". Xingdong mainly has 5v, 12v, 24v, 48v and other DC axial fans.

The cross-flow of a tangential fan, sometimes known as a tubular fan, was patented in 1893 by Paul Mortier and is used extensively in heating, ventilation, and air conditioning (HVAC), especially in ductless split air conditioners. The fan is usually long concerning the diameter, so the flow remains approximately two-dimensional away from the ends. The cross-flow fan uses an impeller with forward-curved blades, placed in a housing consisting of a rear wall and a vortex wall. Unlike radial machines, the main flow moves transversely across the impeller, passing the blading twice. What follows is a more detailed explanation of it and its functions. Below are some details about cross-flow fans and aluminum alloy cross flow fans.

Cross flow fan is also called as tangential blower fan, can be made with DC voltage such 12V and 24V or AC voltage such 100~240V cross flow fan, we have different sizes from smaller to bigger ones, for example, 30 series, 40 series and 60 series, the material of frame is metal and the material of impeller is aluminum alloy, color of frame is black, color of impeller is silver white, which are widely used in air conditioners and air purifiers, the characteristics is big air flow, high air pressure and easily fitted.

A cross-flow fan is a fluid that cross-flow fan through the fan impeller twice, the fluid flows in the radial direction and then flows out in the radial direction. The intake and exhaust directions are in the same plane, and the exhaust body is evenly distributed along the width of the cross-flow fan. Because of its simple structure, small size, and high dynamic pressure coefficient, it can reach a long distance. It is widely used in laser instruments, air conditioners, air curtain equipment, dryers, hairdryers, household appliances, and grain combine harvesters.
